Largest Biochemical Circuit Built Using Small Synthetic DNA Molecules- A DNA-based Device

in technology, medicine, biology, omics

Caltech researchers say they have built the most complex biochemical circuit ever created from scratch. This biochemical circuit was made with DNA-based devices in a test tube that are analogous to the electronic transistors on a computer chip.

Selective Abortion of Female Fetuses in India- Some Questions on the Lancet Article

in medicine

A recent article in the reputed journal Lancet concluded that "selective abortion" of female fetuses, usually after a firstborn girl, has increased in India over the past few decades, and has contributed to a widening imbalance in the child sex ratio.

Flu Infection Can Cause Asthma, Boston Researchers Answer 'Why?'

in medicine

The researchers found a previously unknown biological pathway explaining why influenza induces asthma attacks. When children with asthma get the flu, they often land in the hospital with breathing difficulties. This new finding reveals another potential therapeutic target for asthma.

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.
