Researchers have described how electrical energy naturally produced at the sea floor might have given rise to life.

According to the findings, which also can be thought of as the “water world” theory, life may have begun inside warm, gentle springs on the sea floor, at a time long ago when Earth’s oceans churned across the entire planet.

Hairs can reveal a lot, from your personality to even drug abuse or hormonal changes. Now, add foetus growth in the womb to the hair list.

In a thrilling discovery, a team of researchers including an Indian-origin scientist have found that hair can also reveal the womb environment in which an infant was formed.

They used infant hair to examine the hormonal environment to which the foetus was exposed during development – promising to unleash a wealth of new information in the fields of neonatology, psychology social science to neurology.

If you missed your chance to witness the “blood moon” grace the sky, you’re in luck, as scientists have revealed that he moon will glow red three more times in the next 18 months.

It’s all part of a lunar eclipse “tetrad”: a series of four consecutive total lunar eclipses that happen at about six-month intervals, ABC News reported.

The next one is due Oct. 8, followed by blood moons April 4, 2015, and Sept. 28, 2015, according to NASA.

A new study suggests that the way we chew and eat our food impact our overall consumption.

According to the study, people perceive food that are either hard or have a rough texture to have fewer calories.

“We studied the link between how a food feels in your mouth and the amount we eat, the types of food we choose, and how many calories we think we are consuming,” authors Dipayan Biswas, Courtney Szocs (both University of South Florida), Aradhna Krishna (University of Michigan), and Donald R. Lehmann (Columbia University) wrote.

Do planets have to have a stable tilt like earth to nurture life? Perhaps not as a fluctuating tilt in a planet’s orbit does not prohibit the possibility of life. In fact, sometimes, it helps, a promising research say.

Further, expanding the habitable zone might almost double the number of potentially habitable planets in the galaxy, according to astronomers from University of Washington, Utah-based Weber State University and NASA.

A new modeling done by researchers has suggested that pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable.

Shawn Domagal-Goldman, an astrobiologist at NASA ‘s Goddard Space Flight Center in Greenbelt, Md, said planets like these are far enough from their stars that it would be easy to write them off as frozen, and poor targets for exploration, but in fact, they might be well-suited to supporting life.

Researchers suggest that Mars’ thin atmosphere might have led to its cold, dry conditions.

The results are important because they shed light on how habitable Mars was billions of years ago, and how long any surface water persisted.

Planetary geologist Edwin Kite of the California Institute of Technology and his team measured craters made on Mars by asteroid collisions to get an idea of its past atmospheric pressure, News24 reported.

Kite’s team took a look at 319 craters in Aeolis Dorsa – a 3.6-billion-year-old region showing evidence of past rivers.

A new study suggests that the Tyrannosaurus rex did not need proper arms, because its head and neck were so powerful.

Tyrannosaurs, the family of big predatory dinosaurs that includes T. rex, had necks that were similar to those of modern birds.

So by studying how birds feed, Eric Snively of the University of Wisconsin-La Crosse and his colleagues were able to reconstruct how T. rex went about making a kill, New Scientist reported.

Total lunar eclipse will create “blood moon” for much of the central and western United States.

2014’s first total lunar eclipse, which will occur in the overnight hours, will be visible across most of North America, During a total lunar eclipse, the moon is entirely immersed in Earth shadow, and can take on a dusky “blood red” color due to the scattering of sunlight through the edges of Earth”s atmosphere.

The innocent infants choose their playmates carefully and they are not immune from ‘in-group’ bias, favouring people from same ethnicity over others, a study has found.

Infants can take into account both race and social history (how a person treats someone else) when deciding which person would make a better playmate, said the study.

Babies also value fairness – whether or not someone equally distributes toys – unless they noticed that the experimenter unevenly distributed toys in a way that benefits a person of the same race as the infant, said the study.

Researchers have said that by tracking brain activity when an animal stops to look around its environment they can mark the birth of a memory.

Using lab rats on a circular track, James Knierim, professor of neuroscience in the Zanvyl Krieger Mind/Brain Institute at Johns Hopkins, and a team of brain scientists noticed that the rats frequently paused to inspect their environment with head movements as they ran.

Total lunar eclipse will create ” blood moon” for much of the central and western United States.

2014’s first total lunar eclipse, which will occur in the overnight hours, will be visible across most of North America, South America, Hawaii and parts of Alaska, Fox News reported.

During a total lunar eclipse , the moon is entirely immersed in Earth shadow, and can take on a dusky “blood red” color due to the scattering of sunlight through the edges of Earth’s atmosphere.

If you are 24, you have already reached your peak in terms of your cognitive motor performance, a study reveals.

In one of the first social science experiments to rest on big data, the researchers investigated when we start to experience an age-related decline in our cognitive motor skills and how we compensate for that.

A new study has revealed that short RNA molecules could hold key to understand the physiological processes underlying hereditary trauma.

The study found that traumatic stress alters the amount of several microRNAs in the blood, brain and sperm, while some microRNAs were produced in excess, others were lower than in the corresponding tissues or cells of control animals, which resulted in misregulation of cellular processes normally controlled by these microRNAs.
