A Catalyst That Improves Artificial Photosynthesis Developed

in technology, biology

According to a paper published in the journal Science, University of llinois researchers produced a catalyst that dramatically reduces the energy requirements of artificial photosynthesis. The researchers succeeded in overcoming a major obstacle to the promising artificial photosynthesis technology that simultaneously reduces atmospheric carbon dioxide and produces fuel.

Alzheimer’s Disease Without Amyloid Plaques

in medicine, biology

Amyloid plaques have long been thought to be the cause of neuron loss in Alzheimer’s disease.  Now researchers report that excess of mutated amyloid precursor protein (APP) inside the neurons is sufficient to induce neuron death.  The report challenges the notion that amyloid deposits outside of the cells are necessary for neuron death in Alzheimer’s disease.

ePetri Dish, A Smart Petri Dish From Caltech

in biology, education

The imaging sensor chips in electronic gadgets helped engineers at the California Institute of Technology  transform the way cell cultures are imaged by serving as the platform for a "smart" petri dish, named ePetri.

Dendritic Cell Scientist Wins Nobel Prize

in Medicince, biology

Dendritic cell research got a boost this week when Ralph Steinman won the Nobel Prize for Physiology or Medicine. Sadly, Steinman did not live long enough to receive the Prize, he passed away just three days before the Nobel Prize was announced.

Researchers Report DNA Modifications In Non-dividing Brain Cells

in Medicen, biology

Hopkins scientists report that changes to DNA in brain neurons do occur though these neurons do not divide. They used electric shock to stimulate the brains of live mice. A few hours after administering the brain stimulation, the scientists analyzed two million of the same type of neurons from the brains of stimulated mice.

Unveiling The Biological Clock - A New Clock Gene From Salk

in biology, omics

Researchers at the Salk Institute for Biological Studies have identified a new component of the biological clock, a gene responsible for starting the biological clock from its restful state every morning. According to Salk Institute, the new discovery fills in a missing link in the molecular mechanisms that control our daily wake-sleep cycle.

Singing After Stroke? Don’t Ignore Rhythm

in medicine, biology

When a stroke damages speech areas in the brain’s left hemisphere, sufferers often have severe difficulties speaking – a condition known as non-fluent aphasia. A new study published in the journal Brain may lead the way to new rehabilitative therapies for the speech disorders. 

Exercise During Pregnancy Protects Children From Alzheimer's Disease

in medicine, biology

Based on a study performed with specially bred mice, published in the FASEB journal, researchers say pregnant women who exercise may protect their offspring against long-term neurodegenerative diseases such as Alzheimer's disease.
