Researchers have evaluated the carcinogenicity of the consumption of red meat and processed meat. They classified the consumption of red meat as probably carcinogenic to humans, based on limited evidence that the consumption of red meat causes cancer in humans and strong mechanistic evidence…

People who work in well-ventilated offices with below-average levels of indoor pollutants and carbon dioxide have significantly higher cognitive functioning scores -- in crucial areas such as responding to a crisis or developing strategy -- than those who work in offices with typical levels.

Researchers have identified a molecule that, after a stroke, signals brain tissue to form new connections to compensate for the damage and initiate repairs to the brain.

Not all academic citations are positive ones, and a new paper finds that as many as one in 50 citations in a top immunology journal were critical in nature.

Nighttime hunters like cats and owls, benefit from their big round eyes that let in plenty of light, but humans have more limited abilities to see in the dark. A new article suggests that poor night vision is a common complaint that can be particularly vexing while driving.

Researchers have identified how brain rhythms are used to process music, a finding that also shows how our perception of notes and melodies can be used as a method to better understand the auditory system.

Limited use of general anesthesia with an infant does not cause developmental problems for the child, an international team of researchers is reporting. The study is the largest of its kind and the first randomized study to compare whether general anesthesia in infancy has any effect on…

Investigators have discovered a mechanism behind the spread of neurofibrillary tangles -- one of the two hallmarks of Alzheimer's disease -- through the brains of affected individuals.

Research on the genetic factors contributing to neuropathic pain has been hindered by the lack of a standard approach to assessing its clinical characteristics or 'phenotype.' Now, a report from an expert panel presents a consensus approach to assessing the phenotype of neuropathic pain.

Proteins called cytokines are known to influence immune cell fate, but the process is complex. Researchers examined how a specific cytokine, interleukin-15, influences gene expression patterns in T helper cells.

Aging researchers are studying the connection between cholesterol level and cognitive decline in old age. Carriers of the ApoE4 genetic risk factor for Alzheimer's may be able to reduce their increased risk of cognitive decline by reducing their cholesterol level, especially if they also suffer…

Parents in areas with many immigrants have little reason to fear that a high proportion of immigrant pupils in schools in itself hampers student performance, according to new Norwegian research.

A Spanish research team is investigating how to build a system that recreates human behavior. This technology could be applied to anticipate behavior in socioeconomic crises, create more human-like robots or develop avatars of artificial intelligence which are almost indistinguishable from those…

The sociologist who found that 'A Happy Wife, Means a Happy Life' looked at sadness, worry and frustration -- among the most common negative emotions reported by older adults -- and discovered that men and women in long-term marriages deal with marriage difficulties differently.

A new combination of drugs has been discovered that may be effective against one of the deadliest cancers, malignant melanoma. The combination -- pairing a drug targeted against mutations in the BRAF gene with a second drug that targets another important signaling pathway -- was discovered through…

An evaluation of a statewide shaken baby prevention effort found that the number of calls to a nurse advice line from North Carolina parents who called because of a crying baby were reduced in the first 2 years after the intervention was implemented in 2007. However, the study did not find a…

Anyone who takes medicine to get their blood sugar or blood pressure down – or both – knows their doctor prescribed it to help them. But what if stopping, or at least cutting back on, such drugs could help even more? Two new studies suggest doctors should be doing that more.

Intrinsic neural connections -- called crossmodal mappings -- can be used by assistive devices to help the blind detect their environment without requiring intense concentration or hundreds of hours of training. This new multisensory perspective on such aids (called sensory substitution devices)…

Researchers have uncovered the role played by a family of genes, which can suppress hepatitis C virus (HCV) infection within the liver. The findings shed light on the activity of these genes and how they produce a natural immune response to the virus.

Our brains not only contain learning mechanisms but also forgetting mechanisms that erase "unnecessary" learning. A research has now been able to describe one of these mechanisms at the cellular level.

New research shows an increased risk of large bowel cancer for each 1 cm rise in waist circumference. In addition, in men, there is now evidence that increasing waist circumference in middle age is associated with increased bowel cancer risk.

Certain medications commonly used to treat heartburn and acid reflux may have damaging effects on the kidneys, according to two new studies. The drugs, proton pump inhibitors (PPIs), are among the top 10 class of prescribed medications in the United States.

A new study of more than 25,000 men has uncovered four new genetic variants associated with increased risk of testicular cancer. Testing for these variants combined with all 21 previously identified using genetic sequencing identified men with a 10-fold higher risk of testicular cancer than the…

A five week treatment with the synthetic hormone oxytocin significantly improved social, emotional and behavioral issues among young children with autism, according to new research.

Insulin, the hormone essential to all mammals for controlling blood sugar levels and a feeling of being full after eating, plays a much stronger role than previously known in regulating release of dopamine, a neurotransmitter that helps control the brain's reward and pleasure centers.
