A novel reconfigurable silicon nanowire transistor

in technology

In a recently published paper, researchers report the development of a novel type of nano-transistors which are based on individually gated nanometer scale nanowire heterojunctions where electrons and holes are filtered selectively. 

Children exposed to family violence show increased brain activity

in biology

A new study shows that children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat.

A New Population of Heart Stem Cells

in medicine, biology

Researchers have discovered a new population of adult stem cells in the heart, which could augment the development of new regeneration and repair therapies for people who have suffered heart attack or heart failure, a leading cause of death.

Caltech-Led Team of Astronomers Finds 18 New Planets

in technology

The recent discovery of 18 planets by scientists at the Caltech is the largest collection of confirmed planets around stars more massive than the sun.

Phantom Limb - A New Study Using Anesthesia of the Arm

in medicine

Scientists now provide new information about how the brain generates phantom limbs.  According to the study there is no default position that the phantom moves into after it forms.

Some People Can Hallucinate Colors At Will

in medicine, biology

Scientists have found that some people have the ability to hallucinate colours at will – even without the help of hypnosis. The study focused on a group of people that had shown themselves to be ‘highly suggestible’ in hypnosis.

The study was published this week in the journal Consciousness and Cognition.

Imperfect Graphene Makes Better Chemical Sensors

in technology, environment

A new study shows that chemical sensors made with less perfect graphene may have better sensitivity. Researchers produced graphene chemical sensors with either near-perfect structures or deliberatively defective structures and found that the graphene sensors with edges and line defects were more sensitive in detecting gas analytes. 

How Silkworms Beat Polymer Scientists - The Aquamelt Secret

in technology, biology, omics

A new research shows us how silkworms beat materials scientists by spinning silk with minimum energy expenditure. Scientists demonstrate that natural silks are a thousand times more efficient than synthetic polymers when it comes to forming fibers.
