Study shows resistance to cocaine addiction may be passed down from father to son 
Research from the Perelman School of Medicine at the University of Pennsylvania and Massachusetts General Hospital (MGH) reveals that sons of male rats exposed to cocaine are resistant to the rewarding effects of the drug, suggesting that cocaine-induced changes in physiology are passed down from father to son.

What causes hot flushes during menopause?
Hot flushes affect millions of people, and not just women. Yet, it is still unclear what causes the episodes of temperature discomfort, often accompanied by profuse sweating.

Secrets of gentle touch revealed
Stroke the soft body of a newborn fruit fly larva ever-so-gently with a freshly plucked eyelash, and it will respond to the tickle by altering its movement—an observation that has helped scientists at the University of California, San Francisco (UCSF) uncover the molecular basis of gentle touch, one of the most fundamental but least well understood of our senses.

Targeting neurotransmitter may help treat gastrointestinal conditions
Selective targeting of the neurotransmitter that differentially affects brain cells that control the two distinct functions of the pancreas may allow for new medication therapies for conditions like diabetes, dyspepsia and gastro-esophageal reflux, according to Penn State College of Medicine researchers.

Tongues help noses smell food, and vice versa
We all know that when it comes to enjoying food, taste and smell go hand in hand. But how and where they hold hands in the neural circuits of the brain has been something of a mystery. Neuroscientists have known for a while that odor receptors in the nose send signals to the the brain’s taste center, also known as the gustatory cortex. But does the converse happen? Do taste receptors in the tongue talk to the smell center, the olfactory cortex?

Newly discovered effects of vitamin D on cancer
A team of researchers at McGill University have discovered a molecular basis for the potential cancer preventive effects of vitamin D. The team, led by McGill professors John White and David Goltzman, of the Faculty of Medicine's Department of Physiology, discovered that the active form of vitamin D acts by several mechanisms to inhibit both the production and function of the protein cMYC. cMYC dr

Researchers develop efficient, protein-based method for creating iPS cells
Coaxing a humble skin cell to become a jack-of-all-trades pluripotent stem cell is feat so remarkable it was honored earlier this month with the Nobel Prize in Physiology or Medicine. Stem cell pioneer Shinya Yamanaka, MD, PhD, showed that using a virus to add just four genes to the skin cell allowed it to become pluripotent, or able to achieve many different developmental fates

Anesthesia drugs really do put us to sleep
When patients are put under anesthesia, they are often told they will be "put to sleep," and now it appears that in some ways that's exactly what the drugs do to the brain. New evidence in mice reported online on October 25 in Current Biology, a Cell Press publication, shows that the drugs don't just turn wakefulness "off," they also force important sleep circuits in the brain "on."

Skin hair skims heat off elephants
Body hair in mammals is typically thought to have evolved to keep us warm in colder prehistoric times, but a new study suggests that it may do the opposite, at least in elephants. Epidermal hair may have evolved to help the animals keep cool in the hot regions they live in, according to new research published Oct 10 in the open access journal PLOS ONE by Conor Myhrvold and colleagues at Pr

You are feeling sleepy...
The speed and degree to which the pupil of the eye responds is a standard test for alertness. It has also been used to assess how sleepy or exhausted a person is. Now, research to be published in the International Journal of Bioinformatics Research and Applications suggests that measuring pupil response alone is not enough and that a person's rate of blinking should also be incorporated to

Research may help build a better diabetes drug
Many drugs work by "fixing" a particular biological pathway that's gone awry in a disease. But sometimes drugs affect other pathways too, producing undesirable side effects that can be severe enough to outweigh the drug's benefits.

Biologists from New York University have uncovered new ways our biological clock's neurons use electrical activity to help keep behavioral rhythms in order. The findings, which appear in the journal Current Biology, also point to fresh directions for exploring sleep disorders and related afflictions.

For newborn mice to suckle for the very first time and survive, they depend on a signature blend of scents that is unique to their mothers. The findings, published online on October 4 in Current Biology, a Cell Press publication, reveal that mom's natural perfume consists of odors emitted from the amniotic fluid, which served to nourish and protect those young mice before they were born.

New findings on the workings of the inner ear
The sensory cells of the inner ear have tiny hairs called stereocilia that play a critical part in hearing. It has long been known that these stereocilia move sideways back and forth in a wave-like motion when stimulated by a sound wave. After having designed a microscope to observe these movements, a research team at Karolinska Institutet in Sweden has discovered that the hairs not only move side
