Research findings may accelerate work to safely control diabetes

For those with diabetes, managing blood sugar is a balancing act -- if blood sugar is too high it raises the risk for nerve damage, blindness, kidney failure, and heart trouble, and if too low it can lead to a seizure or unconsciousness.

Altered AHNAK gene may open door to improved treatment for keloid scars

Researchers at Henry Ford Hospital in Detroit have identified a gene that may offer a better understanding of how keloid scars develop and potentially open the door to improved treatment for the often painful, itchy and tender scars.

Study suggests link between neonatal ghrelin and obesity risk

Our subconscious motivation to eat is powerfully and dynamically regulated by hormone signals. The gut-derived hormone ghrelin is one such key regulator, promoting appetite through its effects on neurons in a small region of the brain called the hypothalamus.

Johns Hopkins researchers propose novel cancer-fighting strategy

Existing cancer therapies are geared toward massacring tumor cells, but Johns Hopkins researchers propose a different strategy: subtly hardening cancer cells to prevent them from invading new areas of the body. They devised a way of screening compounds for the desired effect and have identified a compound that shows promise in fighting pancreatic cancer.

Researchers identify novel life-preserving circuit responsible for recognizing threats

Our existence depends on a bit of evolutionary genius aptly nicknamed "fight or flight." But where in our brain does the alarm first go off, and what other parts of the brain are mobilized to express fear and remember to avoid danger in the future?

CSHL researchers describe new pathway that controls fear memories in the mouse brain

Some people have no fear, like that 17-year-old kid who drives like a maniac. But for the nearly 40 million adults who suffer from anxiety disorders, an overabundance of fear rules their lives. Debilitating anxiety prevents them from participating in life's most mundane moments, from driving a car to riding in an elevator.

Researchers reveal link between the microbiome of young mice and later onset of autoimmune disease

Researchers have revealed that the colonization of the gut of young mice by certain types of bacteria can lead to immune responses later in life that are linked to disease.

Crown's first European symposium to focus on use of Translational Platforms in oncology drug discovery

Crown Bioscience, Inc., a leading global drug discovery and development service company, has announced its first European symposium, detailing the use of Translational Platforms including Patient-Derived Xenograft (PDX) models in oncology drug discovery and development. The conference will be held on Wednesday 11th February, at the headquarters of One Nucleus in Cambridge, UK and will welcome experts from renowned pharmaceutical companies and prominent academics working in oncology.

TSRI scientists identify novel synthetic compound that reduces activity of a cancer-related protein

Scientists from the Florida campus of The Scripps Research Institute have identified a novel synthetic compound that sharply inhibits the activity of a protein that plays an important role in in the progression of breast and pancreatic cancers.

Novel drug delivery technique uses graphene to deliver two anticancer drugs sequentially to cancer cells

An international team of researchers has developed a drug delivery technique that utilizes graphene strips as "flying carpets" to deliver two anticancer drugs sequentially to cancer cells, with each drug targeting the distinct part of the cell where it will be most effective. The technique was found to perform better than either drug in isolation when tested in a mouse model targeting a human lung cancer tumor.

New research sheds light on process that controls genes and determines cell fate

For a skin cell to do its job, it must turn on a completely different set of genes than a liver cell — and keep genes it doesn’t need switched off. One way of turning off large groups of genes at once is to send them to “time-out” at the edge of the nucleus, where they are kept quiet. New research from Johns Hopkins sheds light on how DNA gets sent to the nucleus’ far edge, a process critical to controlling genes and determining cell fate.

Resveratrol activates ancient stress response in human cells, shows study

Scientists at The Scripps Research Institute (TSRI) have found that resveratrol, the red-wine ingredient once touted as an elixir of youth, powerfully activates an evolutionarily ancient stress response in human cells.

UCLA researchers uncover potential to restore lost memories in patients with early Alzheimer's

New UCLA research indicates that lost memories can be restored. The findings offer some hope for patients in the early stages of Alzheimer's disease.

Eating habits and brain chemistry: an interview with Dr Kevin Hall

Several times every day, we choose when, where, what, with whom, and how much to eat. Many of these eating decisions have become automatic and don’t require cognitive effort.

Researchers say that misfiring of the brain's control system may underpin compulsions in OCD

Misfiring of the brain's control system might underpin compulsions in obsessive-compulsive disorder (OCD), according to researchers at the University of Cambridge, writing in the American Journal of Psychiatry.

Penn, UGA scientists awarded new contract to develop genome database for microbial pathogens

At the turn of the millennium, the cost to sequence a single human genome exceeded $50 million, and the process took a decade to complete. Microbes have genomes, too, and the first reference genome for a malaria parasite was completed in 2002 at a cost of roughly $15 million. But today researchers can sequence a genome in a single afternoon for just a few thousand dollars. Related technologies make it possible to capture information about all genes in the genome, in all tissues, from multiple individuals.

Broccoli can help reduce HGPS-related defects

Children who suffer from Hutchinson-Gilford Progeria syndrome age prematurely due to a defective protein in their cells. Scientists at Technische Universität München have now identified another important pathological factor: the system responsible for removing cellular debris and for breaking down defective proteins operates at lower levels in HGPS cells than in normal cells. The researchers have succeeded in reactivating protein breakdown in HGPS cells and thus reducing disease-related defects by using a substance from broccoli.
