Woolly mammoths mated with Columbian mammoths, a completely different and much larger species

in biology, omics

A new study suggests that woolly mammoth mated with a completely different and much larger species, Columbian mammoth.  This interesting DNA-based finding sheds new light on the complex evolutionary history of the woolly mammoth.

Adults Are Much Less Likely Than Children to Think Someone Should Be Punished

in medicine, biology, education

Can your age influence your decisions? A new study says that people's moral responses to similar situations change as they age.  The researchers used a combination of brain scanning, eye-tracking and behavioral measures to understand how the brain responds to morally laden scenarios.

Folic Acid Eating Mother Protects Children From Colon Cancer

in environment, medicine, biology

Can folic acid prevent cancer? Colon cancer usually catches up with age; you are at a higher risk if older than 60.  A new study shows that mothers who eat folic acid during pregancy and breast feeding can protect offsprings from colon cancer. 

A New Biomaterial That More Closely Mimics Human Tissue

in technology, medicine, biology

A new biomaterial that more closely mimics the properties of native human tissue has been designed for repairing damaged human tissue. It doesn’t wrinkle up when stretched.

This invention from nanoengineers at the University of California, San Diego marks a significant breakthrough in tissue engineering.

Researchers Recreate Brain Cell Networks With Unprecedented View of Activity Behind Memory Formation

in medicine, biology

Scientists at the  University of Pittsburgh have reproduced the brain’s complex electrical impulses onto models made of living brain cells that provide an unprecedented view of the neuron activity behind memory formation.

Human Astrocytes Cultivated From Stem Cells In Lab Dish by U of Wisconsin Researchers

in medicine, biology

A group of researchers led by University of Wisconsin-Madison stem cell researcher Su-Chun Zhang reports it has been able to direct embryonic and induced human stem cells to become astrocytes in the lab dish. Astrocyte is the most common cell in the human nervous system.

Paraplegic Man Can Stand and Move Legs Voluntarily- Caltech Research, a Ray of Hope

in technology, medicine, biology

Sustained electrical stimulation of the spinal cord neurons and locomotor training sessions for over 26 months enabled a paraplegic man to achieve full weight-bearing standing with assistance and achieve control of some leg movements.

This remarkable research result was published online today in the highly reputed medical journal The Lancet.

The Science of Gut Feeling: Gut Bacteria Influence Brain Chemistry and Behavior

in environment, medicine, biology

Gut feeling has been used to describe visceral emotional reaction to something, not something thoughtful.  Now researchers at McMaster University have scientific evidence to demonstrate that bacteria residing in the gut influence brain chemistry and behavior.
