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 ...

Smoking in pregnancy alters baby’s DNA, organs: study

Smoking while pregnant causes chemical changes to the DNA of the unborn baby or foetus so much that it may predispose them to lifelong health conditions, said new research sending another shockwave across the world. Changes in the chemical structure of the baby’s DNA can be detected from as early as 12 weeks into pregnancy, said the research adding significant weight ...

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 ...

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 ...

Diesel Exhaust Fumes May Harm Genes

A new study has found that exposure of air pollution caused by diesel exhaust fumes just for two hours can lead to fundamental health-related changes in the genes by switching some genes on or switching others off. The researchers stated, “This study shows how vulnerable our genetic machinery can be to air pollution and that changes are taking place even ...

Space DNA Helps to Find Extraterrestrial Life

A unique space experiment has found that DNA has the capability to survive extreme conditions of space and re-entry into Earth’s dense atmosphere – raising the possibility of finding extraterrestrial life. During the experiment, small, double-stranded DNA molecules were applied to the outer shell of the payload section of a rocket. After the launch, space flight, re-entry into Earth’s atmosphere ...

Reason for Old Age Found, Solution Possible Soon: Scientists

The scientists at Arizona State University have found a rare atomic level change at the enzyme telomerase that holds secrets as to how we grow old. The telomerase is a naturally occurring enzyme that maintains telomeres and prevents them from shortening during cell division. Telomeres are found at the ends of human chromosomes and are stretches of DNA which protect ...
