Why Some Are Left-Handed? Study Traces Cause to Gene Activity in Womb

A team of researchers from Ruhr-Universität Bochum have traced the cause of asymmetric gene activity that results in preference for left-handedness to right-handedness much before it was previously thought. Much before the development of the brain and motor cortex link with spinal cord, the baby develops preference for left or right handedness, the said. Epigenetic factors appear to be at ...

Change in body temperature can trigger unexpected cardiac arrest, deaths

Scientists have found a protein that reacts adversely to change in temperature of the body and reacts by triggering heart attacks or even deaths. Cardiac arrest occurs when the electrical routine to the heart dysfunctions and unexpectedly becomes uneven, causing ventricular fibrillation and lessening blood flow to the heart. Now a new study has found that of all the known reasons, alteration ...

Nitrogen, Water Traces on Mars Show Life Was Possible in Ancient Red Planet

The nitrogen sample analysis of Curiosity findings could have made it possible for life organism to survive on Mars. Since the nitrogen found on Mars doesn’t show any evidence of life as the surface of Mars is inhospitable for living organism, the researchers believe that the nitrates found on Mars are ancient, and could have come from non-biological processes like meteorite impacts ...

NASA Reproduces 3 Building Blocks of Life in Harsh Space Conditions

Now that NASA scientists have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory, the question is how would it help the mankind or replicate the mankind in outer space. NASA said its scientists discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions was able to produce the three ...

Biological Clock Clue in DNA Change Helps to Predict Lifespan: Study

Do you look younger than your biological age? Then you have chances of living longer than others whose looks show them older than their actual age. Scientists have identified a biological clock that could help predict your lifespan based on chemical changes in your DNA. Researchers from the University of Edinburgh studied chemical changes to DNA to know an individual’s ...

Remain Young For Long if New Treatment on Telemers Help Curb Cell-Ageing

Remaining young is on everybody’s mind and if the latest finding by scientists turns true, then a new treatment to extend telomeres — protective “end caps” for chromosomes that help keep DNA healthy — may slow the process of cell ageing, keeping us young for longer. With the time, these protective “end caps” become shorter with each DNA replication and ...

What do we Inherit From Parents? Retro-Viruses that make us smarter!

Millions of years old inherited viruses actually play an important role in making the human brain dynamic and multifaceted in its functions, says a study. These endogenous retroviruses that constitute around five percent of our DNA were earlier thought to be just a side-effect of our evolutionary journey. Retroviruses seem to play a central role in the basic functions of ...
