குதிரை கிடைத்தால் லகானை மறந்து விடாதீர்கள்




அதிர்ஷ்டம் என்பது என்ன?

இறைவன் உருவாக்கிக் கொடுக்கும் சந்தர்ப்பம்; அவ்வளவுதான்.

கிடைக்கிற சந்தர்ப்பத்தைக் கெட்டியாக பிடித்துக் கொள்பவனையே அதிர்ஷ்டசாலி என்கிறோம்.

சந்தர்ப்பங்களைத் தேடி அலைகிறவர்கள் பலர்; அது கிடைக்கவில்லை என்று அவர்கள் வாடுவார்கள். அவர்கள் எல்லாம் மதுரைக்கு போவதாக எண்ணிக் கொண்டு சேலம் ரயிலில் ஏறி உட்கார்ந்தவர்கள்!

கிடைத்த சந்தர்ப்பத்தை நழுவ விட்டவர்கள் பலர். அவர்களெல்லாம் ரயிலைத் தவற விட்ட பிரயாணிகள்!

சரியான ரயிலுக்கு சரியான நேரத்தில் போய்ச் சேர்ந்தவனே, தான் விரும்பிய ஊருக்குப் போய் சேருகிறான்.

சரியான சந்தர்ப்பத்தைக் கெட்டியாக பிடித்துக் கொண்டவனே, தெய்வத்தின் உதவியோடு முன்னேறுகிறான்.

'எந்த நேரத்தில் எதை செய்தால் சரியாயிருக்கும்' என்ற தெளிந்த அறிவு எல்லோர்க்கும் வாய்ப்பதில்லை.

உண்மைதான்.

ஆனால் கிடைக்கின்ற சந்தர்ப்பத்தை பயன்படுத்திக் கொள்ளாதவர்கள் எந்தவிதத் தெளிவும் இல்லாதவர்கள்.

வாய்ப்பு கிடைத்ததாலே, முட்டாள் பணக்காரன் ஆனதுண்டு; வாய்ப்பு கிடைக்காததாலே திறமைசாலி தெருவில் அலைந்ததுண்டு.

'இந்த வாய்ப்பு' என்பது இறைவன் காட்டும் பச்சை விளக்கு.

கொத்தவால் சாவடியில் காய்கறி வாங்கி ஜாம் பஜாரில் கொண்டு போய் விற்றால், ஐம்பது ரூபாய் லாபம் கிடைக்கும் என்று உனக்கு தெளிவாக தோன்றினால், அதை உடனடியாக செய்து விட வேண்டும்.

அந்த முதல் லாபத்திலேயே உனக்கு இரண்டாவது யோசனை உதயமாகும்.

வியாபாரத்தில் லாபம் வந்தால் அந்த வியாபாரத்தை  தொடர்ந்து செய்யலாம்.

ஆனால் சூதாட்டத்தில் லாபம் வந்தால் தொடர்ந்து சூதாட கூடாது.

ஒருவனிடம் கத்தியைக் காட்டி நீ ஆயிரம் ரூபாய் வாங்கி விட்டால், அந்த தைரியம் போலீஸ்காரரிடமும் கத்தியைக் காட்டச் சொல்லிப் பிடித்துக்கொடுக்கும்.

சிலர் வியாபாரத்தை சூதாட்டம் போலவும், கொள்ளையடிப்பது போலவும் நடத்துவர். இதை தவிர்க்காவிடில் சர்வ நாசம்தான்.

தர்மத்துக்கு கட்டுப்பட்டு நடப்பதுடன் புத்திசாலி தனமும் வேண்டும்.

சொத்தின் மதிப்பு குறையும் போது அதை வாங்க வேண்டும்.இன்னும் குறையும் என்று எண்ணினால் அது ஏறிவிடவும் கூடும்.

மதிப்பு ஏறினால் அதை விற்று விட வேண்டும்; இன்னும் ஏறும் என்று கருதினால், அது இறங்கி விடவும் கூடும்.

பர்மாவிலும், சைகோனிலும், இலங்கையிலும் எங்கள் நகரத்தார்கள் சொத்துக்களை விற்காமல் கெட்டார்கள். மலேசியாவிலே விற்று கெட்டார்கள்.

கத்தரி  செடி காயைத்தான் தரும்; அதிலே குழம்பு வராது.

கைகாட்டி வழியைத்தான் காட்டும். அதுவும் கூட வராது.

தெய்வம் பாதி; திறமை பாதி.

தெய்வம் வாய்ப்பை காட்டுகிறது. திறமை அதை லாபகரமாக்குகிறது.

உன்னிடம் விதை இருக்கலாம்; உரம் இருக்கலாம். வெள்ளம் போல் தண்ணீர் தரும் கிணறும் இருக்கலாம். நிலத்தில் வளம் இல்லை என்றால் அனைத்தும் வீண்.

ஆனால் வளமான நிலம் உன்னிடம் இருந்து விட்டால் மற்ற அனைத்தையும் நீ உருவாக்கி விட முடியும்.

அந்த வளமான நிலமே வாய்ப்பு என்பது.

பாம்பு நஞ்சு  நிறைந்தது; வேங்கை பயங்கரமானது; யானையின் பலத்தின் முன்னால் மனிதன் எம்மாத்திரம்?

ஆனால், அவற்றை ஆட்டி வைக்க கூடிய திறமை சில மனிதர்களிடம் இருக்கிறது.

உங்களாலும், என்னாலும் முடியுமா? அந்த வாய்ப்பும் சிலருக்கே அமைகிறது.

அதனால்தான், வாய்ப்பு என்பது இறைவன் அளிப்பது என்றேன். அதை முறையாக பிடித்துக்கொண்டு முன்னேறுவதை அதிருஷ்டம் என்கிறேன்.

எழுதுவதற்கு பத்திரிக்கைகளோ படங்களோ இல்லை என்றால் நான் யார்?

நான் ஓர் அதிர்ஷ்டக்காரன்.

காரணம் இறைவன் எனக்கு அளித்த வாய்ப்பை மனித யத்தனதால் எவ்வளவு காப்பாற்றிக் கொள்ள முடியுமோ, அவ்வளவு காப்பாற்றிக் கொள்கிறேன்.

ஹிட்லருக்கு  கிடைத்த வாய்ப்பு, ஆணவத்தால் அழிந்தது.

சோவியத் மக்களுக்கு கிடைத்த வாய்ப்பு, திறமையினால் வளர்ந்தது.

வாய்ப்பை தவற விடுபவனே துருதிஷ்டசாலி.

அந்த வாய்ப்பு எல்லோர்க்கும் எப்போது வரும்?

அது முன் கூட்டியே தெரிந்து விட்டால் இறைவனை ஏன் நினைக்கப் போகிறீர்கள்?

A Killer Smile


Lord Krishna“When a devotee with all his heart and soul serves Krishna, dresses Him in nice garments and gives Him a flower, Krishna smiles. If you can get Krishna to smile upon you just once, your life's goal is fulfilled.” (Shrila Prabhupada, Teachings of Lord Kapila, Ch 7)
Shyamasundara, the original and ever existing form of the Personality of Godhead, has an inexhaustible reservoir of sweetness just ready to flow onto whoever is sincere enough to look at His wonderful face and body. The jivas, the conditioned living entities that are technically part of the marginal energy emanating from the Supreme Spirit, have exercised their freedom by turning their faces away from God. As nothing can be separated from the origin of everything, the material nature and all its miserable components are certainly non-different from the Supreme Lord, but since they are not part of His personal, internal energy, their association cannot bring anywhere near the level of satisfaction to the heart so desperately looking for eternal pleasure that one simple and sincere glance at the smiling face of the Personality of Godhead can. From the wonderful prescriptions provided by the sweetheart of a devotee and saint, His Divine Grace A.C. Bhaktivedanta Swami Prabhupada, we find an easy way to bring to our vision that enchanting smile, an image which subsequently paints a mental picture that won’t go away anytime soon. Indeed, Krishna’s smile is so beautiful that it will kill the pride of even the staunchest of atheists.
“Dear Krishna, You are the killer of all the fears of the inhabitants of Vrindavana. You are the supremely powerful hero, and we know that You can kill the unnecessary pride of Your devotee as well as the pride of women like us simply by Your beautiful smile.” (Songs of the gopis, Krishna, The Supreme Personality of Godhead, Vol 1, Ch 31)
Radha and KrishnaDoes Krishna exist? Aren’t the stories found in sacred texts like the Ramayana and Shrimad Bhagavatam just mythological? After all, what rational human being would ever believe in flying monkeys, children lifting gigantic hills, or planets managed by people? Surely these were all concoctions borne of ignorance, the mental speculations of those who didn’t have the advanced knowledge of material science available today. But if such a conclusion were to be followed, then the entire breadth and scope of Vedic literature would have to be discounted. This includes the very existence of Krishna and all the references to geographical locations that are known to exist in real life. In addition, the very tangible information pertaining to medical science and the movements and distances of the different stars in the sky would also have to be ignored. The famous teachings of the Bhagavad-gita, where knowledge pertaining to material nature, the properties of spirit, the reason for the continuation of conditioned life, and the way to get out of the clutches of illusion are very concisely and fully presented, would also have to be discarded.
To cherry-pick certain statements and label them as valid while simultaneously ignoring others as being imaginary is not a very scientific way of accepting information. Using skepticism, any theory can be debunked and thus labeled as false. After all, anyone can say anything. Even newspaper stories, which are respected because of the stature of the originating establishment and the supposed editing and fact-checking that is done prior to a paper’s release, are known to be fabricated from time to time. In actuality, authority is most often determined by first testing the validity of the prescriptions provided and the information presented. For instance, we accept the information from our parents relating to the circumstances of our birth and who our siblings are. Based on the accuracy of that information, we can then tag our parents as authority figures. The same principle applies to virtually every type of information transfer. We know that past world leaders and historical personalities existed and performed activities because of the documented sense perceptions contained within books. Anyone could easily question the authenticity of these works and thereby delegitimize both the books and the existence of the people described within the pages.
NewspaperThe proof that the documented evidence relating to the Supreme Lord and His pastimes is true can be found in the results that come from following the prescriptions provided. A principle Vedic instruction, among many other important points of fact, is that mankind is part of the spiritual energy, one which exists eternally and originally without delusion in an imperishable land. As soon as one’s sincere desire is to return to the original realm, all miseries and pains vanish. Shifting desire in the right direction requires a change in consciousness, which serves as the primary indication of pleasure or pain. Regardless of the present circumstances or the level of material accumulation, the thoughts within the mind can put the individual into a pleasant or miserable condition. As consciousness is the key to finding eternal freedom, it must be focused on something tangible, something real.
The Vedas, the ancient scriptures of India, recommend that the mind be focused on the names, pastimes, qualities and forms of the Supreme Personality of Godhead, whose original form is described as being all-attractive; hence the name “Krishna”. While the different traditions emanating from the Vedas, which can be likened to branches growing from the root that is the source of all Vedic wisdom, may ascribe different names and forms for the original entity, there is still no doubt that God is a person and that His transcendental body is attractive. Some take Vishnu, or the four-handed form of the Absolute Truth, to be the original source, while others even accept Lord Rama, the warrior prince expansion of Bhagavan, to be the fountainhead of all incarnations. Regardless of the identification, the fact remains that the Absolute Truth is capable of providing supreme bliss. Even if Vishnu, Rama, or some other non-different form of Godhead is taken as the original, there is still no doubt about Krishna’s attractiveness. His smile is as sweet as they come, so anyone who is fortunate enough to worship Him on a regular basis will reap sublime benefits.
GovindaHow can we worship Krishna if we don’t believe in His existence? Surely there will be skepticism in the beginning, as the accounts of the wonderful and amazing found within the Vedas make believing in the Supreme Spirit and His ability to hear our sincere prayers a little difficult. But anyone who is even fortunate enough to hear about Krishna from an authorized source, a person who has unflinching faith in the merciful and kind nature of Govinda, the pleasure-giver of the senses and the cows, will have their dormant Krishna consciousness aroused eventually. Even the atheists, the avowed haters of God, the disbelievers in religion, worship Krishna to some degree or another. The soul is filled with a blissful nature that never goes away. In the conditioned state, when there is separation from the personal aspect of the Supreme Spirit, the loving propensity gets misdirected towards worldly objects. Indeed, missing the proper target of service is the root cause of all pain and misery.
Love manifests in service. The attitude which seeks to put a smile on someone’s face steers activities. The hopeless romantic tries their best to bring happiness to their paramour. To this end, they will whisper sweet nothings in the ear, write love letters, compliment the appearance and attributes of their beloved, and take great measures just to maintain the pleasure of the object of their service. The pet-lover will go to great lengths to evoke just one affectionate embrace from their cat or dog. The dedicated servant of the nation will risk their lives to protect the innocent, and one simple “thank you” is enough to keep them enthusiastically committed to their service. Similarly, the politician receives satisfaction from seeing the smiling faces of their constituents after a victory in an election.
Lord KrishnaTo have the vision of a smiling face, so many avenues for service are travelled down. Not surprisingly, the same process, but in a purified form, when directed at the proper recipient of love and affection, can bring about the best result. Just one smiling glance from the face of the Supreme Lord Krishna can cause a permanent shift in consciousness. As the transcendental smile is infectious, it can cure the conditioned soul of the material disease, whose acute onslaught has led to a gradual descension into hellish life signaled by a virtual absence of spiritual awareness. The effects of Kali Yuga, the age we currently live in, are such that adherence to dharma, or religious principles, is practically nonexistent. The concept of a regulative system and its necessity are still there, but since the ultimate objective is sense gratification, or enjoyment without Krishna, the principles instituted don’t work and lead to nothing more than a more opulent animal life. The differences between the human beings and animals are subtle and can be tied directly to intelligence. The human mind has a higher potential for the acquisition of knowledge, so unless that opportunity is fully availed of, the resultant lifestyle of eating, sleeping, mating and defending will be no different from a dog’s or hog’s.
Okay, so seeing Krishna smile should be one of the main goals in life, but how do we go about making this happen? Where does Krishna live? How can we see Him? As He is all pervading, Krishna is everywhere. The key is to properly train the eyes to be able to notice His presence. Just as the microscope is required to see atoms and elements that are impossible to be noticed by the naked eye, a special training is required to detect the presence of the only person whose beauty never diminishes, the Supreme Lord who has a blissful and eternal form.
Shrila PrabhupadaIn this regard Shrila Prabhupada has provided a nice roadmap, prescriptions aimed at receiving the darshana of the smiling face of the Lord. The first requirement is that there be a willingness to serve from the devotee, a mentality that is accepted with full heart and soul. The simplest and most effective method of transcendental service is the regular chanting of the holy names, “Hare Krishna Hare Krishna, Krishna Krishna, Hare Hare, Hare Rama Hare Rama, Rama Rama, Hare Hare”. This wonderful sound vibration serves as the perfect prayer, as it is devoid of any desire for sense gratification or alleviation of distress. Who among us hasn’t prayed to God for something? “Oh please Lord, just help me out this one time. I don’t ask You for much, so if You come through for me this one time, I will never bother You again.” Chanting the holy names is different from any other religious practice because it simply requests the presence of the Supreme Spirit within the consciousness of the otherwise forgetful individual. Indeed, the recitation of the name itself brings about the requested association, as the name is not different from the Supreme Personality it represents.
“Let there be all victory for the chanting of the holy name of Lord Krishna, which can cleanse the mirror of the heart and stop the miseries of the blazing fire of material existence. That chanting is the waxing moon that spreads the white lotus of good fortune for all living entities. It is the life and soul of all education. The chanting of the holy name of Krishna expands the blissful ocean of transcendental life. It gives a cooling effect to everyone and enables one to taste full nectar at every step.” (Lord Chaitanya, Shikshashtaka, 1)
When chanting is practiced regularly, the mirror of the heart is gradually cleansed, thus causing a purification of consciousness. The more one chants sincerely the more the heart and soul get attached to the sublime engagement of devotional service, or bhakti-yoga. Service to the Divine can involve hearing, chanting, remembering, worshiping the deity, and many other processes. The deity is the wonderful benediction granted to the souls just dying to have more outlets for their service. By taking material elements such as wood, stone or marble and crafting a statue or picture representation based on the descriptions of Krishna’s form found within the sacred texts, the resulting object becomes non-different from Krishna and thus worshipable. It is an error to think that the spiritual land is without variegatedness or form. If our perishable land was the only place that contained prakriti, or matter, then the spiritual sky would immediately become an inferior place. Though both places have visible substances, the difference lies in the makeup of the matter and its effect on consciousness. The spiritual land is filled with daivi prakriti, or divine matter. As such, the residents of the Vaikuntha planets, the spiritual sky that is free of anxieties, don’t see any difference between matter and spirit. In the conditioned state, our bodies are ever changing, with the full forms being regularly discarded and accepted through the events of birth and death. But in the spiritual sky, where there is association with daivi prakriti, there is no difference between body and spirit.
Lord KrishnaWhen the deity is constructed by devotees following authorized instructions and recommendations, its comprising material elements become completely spiritual. The previously ordinary prakriti turns into daivi prakriti through its association with Krishna. When the deity gets installed and is served regularly, the devotees have a tangible object of worship, a way to see God all the time. Those who don’t believe in Krishna or who remain insistent on their dogmatic principles will be bereft of this divine association. They will take the deity to be a mere idol, some mentally concocted object of worship. In reality, a spiritual discipline which ignores the potency and validity of deity worship must and will always be second class. After all, regardless of the spiritual tradition, the need for the purification of consciousness cannot be argued against. Even in material endeavors such as performing well on a job or graduating from school require a purification of thoughts and a steady focus on the task at hand. In spiritual life, if the ability to worship a tangible object with body, mind and soul is denied, then the consciousness is left to focus on everything except the Supreme Lord. Thus the very restriction on outward worship, which is not based on any rational thought, becomes the strongest impediment towards the stated objective, that of attaining salvation.
“If one offers Me with love and devotion a leaf, a flower, fruit, or water, I will accept it.” (Lord Krishna, Bhagavad-gita, 9.26)
After the deity is erected and the devotee maintains their steady chanting routine, if they can offer some garments, food, or a flower with sincerity, there is every chance of getting Krishna to smile. The acute observer may interject at this point and say, “How can the appearance of the deity change? Once the face is carved out and a smile is put on Krishna’s face, how can that image ever be altered?” Once again, the issue boils down to the vision of the observer, and more importantly, its level of purity. They say that a picture is worth a thousand words; so anyone who looks at an image will have different thoughts and judgments. If we were to look at the same picture at different times of the day, we may perceive different aspects and notice certain features that were previously overlooked. Our level of consciousness thus determines the nature of our vision.
Lord KrishnaWhen there is full sincerity in the bhakti attitude, and when something nice is offered to the Supreme Lord with full faith, there is no doubt that the smile seen on the deity will increase in potency and beauty. Once this smile is seen, when the vision of the observer has been purified to the point that the transcendental smile emanating from the spiritual world is perceived just once, the goal of life is fulfilled. Does this mean that seeing Krishna’s smile gives us full license to take part in sinful activities afterwards? Since only the sincere devotee gains the vision necessary to accurately perceive of the killer smile coming off the deity, there is no chance for falling down from the elevated platform of divine consciousness once the grand vision is received. Krishna’s smile is so attractive that the onlooker will want a repeat of the same miraculous vision day after day. As such, the end-goal of a shift in consciousness is automatically achieved. May that wonderful smile of the kindest person known in all the worlds be forever ingrained in our mind’s eye, and may we never again make the grievous and foolhardy transgression of neglecting His service.

The learning puzzle

The learning puzzle

 Psychology & Psychiatry 
In a collaborative study, researchers found that incentives raised IQ scores by 10 points on average, with greater gains for lower-IQ participants.
Gone are the days of using careful pen strokes to change "Ds" to "Bs" on report cards. Students now have access to far more advanced technology—Photoshop for instance, can work wonders. But what if all the effort that went into dodging academic accountability could instead be channeled into a hunger for learning? Questions like this have long been driving Angela Lee Duckworth, Assistant Professor of Psychology, to investigate new ways to improve student outcomes.
One of Duckworth's main avenues of research involves motivation and its potential effect on IQ testing. Her collaborative study on the topic was recently published in the journal Proceedings of the National Academy of Sciences, and has received wide media attention. Duckworth and her team synthesized findings from prior studies that tested the effects of incentives on IQ scores. They found that incentives raised IQ scores by 10 points on average, with greater gains for lower-IQ participants.
Duckworth's interest in self-control and motivation in young students began when she was an undergraduate at Harvard. She spent the majority of her free time volunteering as a tutor and Big Sister. Upon completion of her master's at Oxford, she worked a brief stint at a consulting firm but knew her true calling was back in education.
“I took a job as a math teacher,” she says. “These questions of motivation kept popping up, and it was like a puzzle for me: I knew if I could reach them, every single one of these kids had the potential to be an accomplished student—what I wanted to teach them was within their intellectual reach. And so I decided that in order to start solving this puzzle, I would need a background in psychology, which ultimately brought me to Penn.”
Duckworth sought out Martin Seligman, Penn faculty member and founder of positive psychology. She met with him in person, and he encouraged her to apply. As part of her Ph.D., she focused on trying to understand self-control in children. Qualities, like grit—the term Duckworth uses to describe individual perseverance—are distinct from talent or raw intelligence, she says. Self-control and grit are dispositions to put forth effort when the rewards for that effort are deferred—and such dispositions may in theory be improved through deliberate intervention.
“We have partnerships with Philadelphia and New York public schools that allow us to measure, and sometimes even intervene, in student lives,” Duckworth says. “These educators are open to any and all innovations—anything to help improve these kids'; education. What we've found, examining the way emotions play out in children, is that those who are able to take a step back from their situations and put it in perspective are much better at controlling themselves.”
Duckworth and her collaborator Gabriele Oettingen at New York University also developed an intervention program in which children are asked to articulate a wish related to their academic progress. Children are then prompted to elaborate, mentally and in writing, on why they chose that. Finally, children list an obstacle to their wish and create a short plan stating when where, and how they will get around it. This strategy, based upon years of prior research with adults, helps turn “high expectations” into actual behavior change.
“Increasing self-control would not necessarily mean children working longer and longer hours. Such a picture would be grim indeed,” Duckworth says.“If you look at world-class performers—Olympic-level athletes, for instance—their most deliberate, strenuous training takes about a four–hour period daily. This suggests that if we can improve the quality of the work children do, improve their concentration and effort, we should vastly increase the efficiency of their studying and learning time. So, paradoxically, and wonderfully, we should free up more time for play, running around and just enjoying childhood.”

A Time to Kill

A Time to Kill

on 
sn-morality.jpg
Trolleyology. People find it difficult to take actions that kill people, even if it saves more lives.

A runaway trolley is about to kill five railroad workers. The only way to stop it is to shove a huge man next to you onto the tracks. Would you kill that man to save five?
That is one of the standard moral dilemmas that scientists are using to study how people decide between right and wrong. But is it the best example? When was the last time you faced a runaway trolley?
To see how people deal with more realistic choices, Joshua Greene, a psychologist at Harvard University, and his undergraduate student Katie Ransohoff, turned to medicine and public health. They recruited 84 medical doctors and 69 public health professionals—people who manage health resources such as Medicare or plan vaccination campaigns but don't treat patients—and posed the sort of moral dilemmas that can crop up in their professions. For example: To save the lives of several patients who need brief access to life support, you need to pull the plug on a more gravely ill patient and redistribute the limited supply of machines in a hospital. In another example, you must decide between saving a few lives now with very expensive treatments or preventing many more deaths with thousands of cheap diagnostic tests. The researchers also posed the standard series of dilemmas involving the runaway trolley. As a control, they also quizzed 110 people from unrelated professions.
The doctors' decisions in both the trolley and the medical dilemmas were not statistically different from the control group, Greene reported last weekend at the annual meeting of the Association for Psychological Science in Washington, D.C. Only 12% of doctors were willing to kill a man to save the five railroad workers, for example. But there was a wide gap between doctors and their administrators: 21% of the public health professionals said that killing the man was the morally correct action to take. The same trend held for medical decisions. Nearly half of public health professionals were willing to pull the plug on a patient's life support to save others, compared with less than a third of doctors.
The results make sense in light of doctors' oath to "do no harm," Greene says. He points out that some problems, such as the overprescription of antibiotics that leads to widespread resistance among bacteria, do require doctors to sacrifice the interests of their patients for the greater good—and yet doctors continue to overprescribe. The trolley dilemmas may seem artificial, Greene says, but they represent extreme versions of moral decisions "we make in our everyday lives."
The next step would be a study that tracks public health professionals before and after their training, says Daniel Wikler, a bioethicist at Harvard School of Public Health in Boston, who helped Ransohoff design the medical dilemmas. Does an education in public health make people more willing to sacrifice an individual for the greater good, he wonders, or do such people gravitate to this field in the first place? People clearly differ in their moral reasoning, but whether those differences are due to nature or nurture remains to be seen.

Hungry Worms From Hell

Hungry Worms From Hell

sn-worm.jpg

Three kilometers beneath Earth’s crust, in a realm known as the subsurface, temperatures in the thick rock are well over 40°C, and the oxygen-poor water chokes out familiar life. Here, slow-growing bacteria and other microbes flourish in masses called biofilms. A ravenous predator also survives in these hellish conditions: a roundworm that researchers describe today as the first multicellular organism to be found in the deep subsurface of Earth.
Eleven years ago, while studying the microbes that live in water-filled rock fractures in South African gold mines, geomicrobiologist Tullis Onstott of Princeton University noticed wormlike organisms living in cultures taken from 1.3 kilometers below the surface. “Well, I’m not a worm kind of guy,” Onstott says. So he contacted Gaetan Borgonie, a nematologist at Ghent University in Belgium, who collected and filtered tens of thousands of liters of water samples from five mines in the area to find the rare creatures, which belong to the worm group called nematodes. In addition to some previously described nematodes, which scientists had never before seen living at this extreme depth, the researchers discovered a new species of nematode that subsists on microbes and requires only trace amounts of oxygen. They named the deep-living, heat-loving species Halicephalobus mephisto. The name refers to Faust’s devil, Mephistopheles, and means “he who loves not the light” in Greek.
In their paper, published today in Nature, the researchers describe H. mephisto as physically similar to surface nematodes, about half a millimeter long and having evolved to be fonder of devouring subsurface bacteria than of dining on the common surface bacterium Escherichia coli. The nematodes are extremely rare because there’s so little oxygen in their environment and they need to eat about 10,000 bacteria per day to survive.
The researchers carbon-dated dissolved organic molecules in water from the vents. They found that the water had been there for somewhere between 3000 and 12,000 years, suggesting that the drillers didn’t bring the oxygen (or the worms) down with them. David Smith, an oceanographer at the University of Rhode Island, in Narragansett, says that although contamination is always a “tricky issue,” the researchers show plenty of evidence of careful handling to support their conclusions. He calls the findings “eye opening” and expects they will encourage other researchers to start looking for multicellular creatures far beneath Earth’s surface.
Marine microbiologist Andreas Teske of the University of North Carolina, Chapel Hill, was not surprised that the first multicellular subsurface organism was a nematode; the worms are among the hardiest creatures on the planet. “If all other [nonmicrobial] life was extinguished, the survivors would be nematodes,” he says.
Onstott says that his group is now working with the J. Craig Venter Institute to sequence H. mephisto’s genome. They hope to discover how the worm can cope with high temperature and low oxygen. The molecular mechanisms, Onstott speculates, may be similar to those of other subsurface organisms such as yeast and fungi. But Teske, who says that there’s a “world of difference” between a predatory worm and a yeast cell, thinks there could be huge surprises.
The study is “another step forward in finding life in places you don’t expect it,” says Michael Meyer, an astrobiologist who is the lead scientist for NASA’s Mars Exploration Program in Washington, D.C. “The discovery of multicellular organisms in the Hadean subsurface world raises the unthinkable possibility there could be multicellular life on Mars.”
But Teske cautions against “wild speculation” about the impact of the study on the search for extraterrestrial life, because H. mephisto isn’t a completely isolated species but has cousins on the surface.
As for Onstott’s group, they are trying to expand the subsurface life panoply even more. “We have worms from hell; next we’ll be looking for viruses from hell,” he says.

Ancient Female Ancestors Roamed Far and Wide for Mates

Ancient Female Ancestors Roamed Far and Wide for Mates

When it came time for members of the human family to find a mate in South Africa about 2 million years ago, it was the females, not the males, who made the first move. A new study of the teeth of 19 australopithecines from cave sites in South Africa suggests that females moved away from their birthplaces far more often than the larger males, who stayed surprisingly close to home and kin.
For several decades, researchers have debated whether early human ancestors lived in close-knit social groups made up of related brothers and fathers, with new genes introduced by female mates gathered from other groups. Chimpanzees follow this pattern too, but in most primates, new males move into groups of related females; in gorillas, for example, one male lives in a harem with many related females. It has been a “monumental task” to test models of the social organization of early members of the human family, known as hominins, says Matt Sponheimer, a co-author of the new study and a paleoanthropologist at the University of Colorado, Boulder. “It’s as if someone told you to investigate the ecology of a giraffe but you were forbidden to observe them in the wild and confined to a room that contained a relatively small number of giraffe bones.”
In recent years, though, scientists have refined a nondestructive method that can reveal what ancient hominins ate and what type of ecological zones they inhabited. Researchers use lasers to ablate tiny sections of tooth enamel, less than 1 millimeter long, which releases two isotopes (or two forms) of the element strontium, so-called 87SR and 86SR. The ratio of those two isotopes reflects the region where individuals lived as children—when their teeth were forming—because the strontium from soil is incorporated into the plants and animals that they ate.
Lead author Sandi Copeland, a paleoanthropologist at the University of Colorado, Boulder, along with Sponheimer and international colleagues, analyzed tooth enamel in 19 individuals from two species,Australopithecus africanus and Paranthropus robustus, two members of the human family that were closely related to our direct australopithecine ancestor. The teeth came from two famous South African caves, Sterkfontein and Swartkrans. When they measured the ratio in the larger molars and canines, presumably from males, they found that before age 8, males fed primarily on dolomite soils around the caves. But at least half of the individuals with smaller teeth, presumably females, fed elsewhere, away from the local dolomite soils, when they were young. The pattern held for both species.
“This is the first direct evidence that exists for dispersal patterns among early hominins,” Copeland says. The findings, reported online today in Nature, suggest that such patrilocal organization of social groups is ancient in human ancestors, perhaps dating back to the common ancestor we shared with chimpanzees, as some researchers have proposed.
Copeland isn’t sure why males would move less than females in a region where there were no natural barriers. She plans to see if the pattern holds in australopithecines in other parts of Africa to see if this was the usual way australopithecines organized their clans. Regardless, “Copeland and her colleagues have come up with an innovative way to test this model, and in the process, they have developed the very first direct evidence of early hominin social organization,” says paleoanthropologist Peter Ungar of the University of Arkansas, Fayetteville. The new method should also reveal other ancient behaviors. “These results have implications for understanding australopithecine diet, group size, predator avoidance, and home-range size,” paleoanthropologist Margaret Schoeninger writes in a commentary published online today in Nature.
