Scientist finds first evidence of a living memory trace

An international team of scientists for the first time has detected a memory trace in a living animal after it has encountered a single, new stimulus.

Sperm stem cells research provides exciting findings

New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body.

Olfactory epithelium plays a critical role in pheromone detection

Howard Hughes Medical Institute researchers have discovered that pheromones essential for mating behavior in mice are recognized by the nose and not by the vomeronasal system, as researchers had long suspected.

First step in exploring the GnRH reproduction-related circuitry in the brain

Howard Hughes Medical Institute researchers have discovered a vast network of neurons in the brain of mice that governs reproduction and controls the effects of reproductive status on other brain functions.

LGC licenses first DNA test for response to schizophrenia treatment from the Institute of Psychiatry, King’s College London

LGC, Europe's leading independent analytical laboratory providing advanced chemical, biochemical and forensic analysis, has announced an exclusive agreement with King’s College London to offer the first pharmacogenetic screening service which will predict whether a patient with schizophrenia will respond positively to the antipsychotic drug clozapine.

New Flu Chip can determine the genetic make-up of types of flu virus in 11 hours

A novel "Flu Chip" developed at the University of Colorado at Boulder that can determine the genetic signatures of specific influenza strains from patient samples within hours may help world health officials combat coming epidemics and pandemics.

Sleeping sickness parasite shows how cells divide their insides

Researchers at Yale have brought to light a mechanism that regulates the way an internal organelle, the Golgi apparatus, duplicates as cells prepare to divide, according to a report in Science Express.

Talk therapy effective treatment for seasonal affective disorder

The alterations start every year around October just after the end of daylight savings time. For most, the clock shift just adds an hour to the weekend -- but for sufferers of seasonal affective disorder, a syndrome involving recurring bouts of depression during fall and winter months, it marks the beginning of a difficult time of year when many forgo an after-work run for a nap, watch television instead of walk the dog, or sleep later in the morning.

Bouncing helicases possibly play a preventative role in keeping the genome intact

Researchers studying how proteins called helicases travel along strands of DNA have found that when the proteins hit an obstacle they snap back to where they began, repeating the process over and over, possibly playing a preventative role in keeping the genome intact.

Gold nanorods injected into the bloodstream may be used to develop an advanced medical imaging tool

Researchers at Purdue University have taken a step toward developing a new type of ultra-sensitive medical imaging technique that works by shining a laser through the skin to detect tiny gold nanorods injected into the bloodstream.

Method to count the absolute number of individual protein molecules inside a living cell

Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively.

Cervical cancer vaccine shows promising results but smear tests still vital

Hopes of an end to routine smear testing have been raised by promising results achieved by a prototype cervical cancer vaccine.

Personalized medicine to improve the outcome for breast cancer patients

As cancer remains a leading cause of death in the United States, early detection and treatment are critical keys to improving the survival rate. Yet, an individual's response to treatment varies considerably, even among cancers of the same histological type.

Glucose test device for diabetics that does not involve pricking the finger

A Syracuse University chemistry professor has patented a device that aims to make painful fingerstick testing of glucose levels a thing of the past for diabetics.

Researchers find gene that is important for the control of fundamental rhythms in nematode worms

University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping.

Scientists genetically modify male mosquitoes to express a glowing protein in their gonads - may help control the mosquito population

By providing a way to quickly sex mosquitoes, the advance paves the way for pooling large numbers of sterile males which could be used to control the mosquito population.

Researchers have successfully combined computer modeling and experimental results in folding studies for small proteins

In unprecedented new research, scientists at Rice University have combined theory and experiment for the first time to both predict theoretically and verify experimentally the protein-folding dynamics of a large, complex protein.

New method to measure circadian cycles

Everyone knows morning people and late-night owls. The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying genetic causes), scientists have had to rely on prolonged behavioural observation.
