Mouse study suggests response to injury-induced growth factors can be revived

Brain and spinal-cord injuries typically leave people with permanent impairment because the injured nerve fibers (axons) cannot regrow. A study from Children's Hospital Boston, published in the December 10 issue of the journal Neuron, shows that axons can regenerate vigorously in a mouse model when a gene that suppresses natural growth factors is deleted.

Embryonic signalling pathways suggest a new therapeutic approach to recover from heart attack

Almost a century after it was discovered in fruit flies with notches in their wings, the Notch signalling pathway may come to play an important role in the recovery from heart attacks. In a study published today in Circulation Research, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, are the first to prove that this signalling pathway targets heart muscle cells and thus reveal its crucial role in heart development and repair

Social scientists say compassion is humans' strongest trait

Researchers at UC Berkeley are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body of evidence to show we are evolving to become more compassionate and collaborative in our quest to survive and thrive.

Behavioral intervention can improve cognitive performance in children

Carnegie Mellon University scientists Timothy Keller and Marcel Just have uncovered the first evidence that intensive instruction to improve reading skills in young children causes the brain to physically rewire itself, creating new white matter that improves communication within the brain.

Historical study reveals stress was a apart of ancient Peruvian's daily lives

The first study of its kind, published in the Journal of Archaeological Science, detected the stress hormone cortisol in the hair of ancient Peruvians, who lived between 550 and 1532 A.D.

Genetic variations in Sonic Hedgehog pathway associated with response to standard immunotherapy

Genetic variations in the Sonic Hedgehog pathway increase the likelihood of recurrence, reduce survival time and limit response to therapy for people with non-muscle invasive bladder cancer, scientists from The University of Texas M. D. Anderson Cancer Center reported today at the American Association for Cancer Research Frontiers in Cancer Prevention Research Conference.

Dermal stem cells may be useful for treating diabetic ulcers and neurological disorders

Scientists have discovered a new type of stem cell in the skin that acts surprisingly like certain stem cells found in embryos: both can generate fat, bone, cartilage, and even nerve cells.

Robarts researcher identifies protein which regulates cell suicide

When cells experience DNA damage, they'll try to repair it. But if that fails, the damaged cells are supposed to self-destruct, a process called apoptosis. A cancer researcher at Robarts Research Institute at The University of Western Ontario has identified a protein that regulates apoptosis, a new discovery which has implications for both the diagnosis and treatment of cancer. Caroline Schild-Poulter's findings are now published online in the journal Molecular Cancer Research.

New protein discovery may serve as potential marker of drug addiction

Scientists are adding additional brush strokes to the revolutionary new image now emerging for star-shaped cells called astrocytes in the brain and spinal cord. Their report, which suggests a key role for astrocytes in morphine's ability to relieve pain and cause addiction, appears online in ACS' Journal of Proteome Research, a monthly publication.

Personality tests can predict success rate of medical students, says new study

With medical schools flooded with applications, three industrial-organizational psychologists have conducted a study to determine if giving personality tests to prospective students would enable admissions officers to better predict which applicants will be successful.

Smell and sexual reproduction

Humans have the same receptors for detecting odors related to sex as do other apes and primates. But each species uses them in different ways, stemming from the way the genes for these receptors have evolved over time, according to Duke University researchers.
