Researchers have discovered what causes the sleep homeostat -- a switch in our brains -- to flip and wake us up. The discovery brings us closer to understanding the mystery of sleep.

For a cell in an embryo, the secret to becoming part of the baby's body instead of the placenta is to contract more and carry on dancing, scientists have found. The study could one day have implications for assisted reproduction.

Outpatient cutaneous surgical procedures are common and surgical gloves are standard practice to prevent postoperative surgical site infection. But, is there a difference in SSIs when sterile vs. nonsterile gloves are used for these minor procedures? A systematic review and meta-analysis of the…

A groundbreaking scientific study has found one way an RNA binding protein may contribute to ALS disease progression.

In work that aims to protect soldiers, a team of scientists has created a material that is highly breathable yet protective from biological agents. This material is the first key component of futuristic smart uniforms that also will respond to and protect from environmental chemical hazards.

Researchers have unraveled the structure and function of bacterial decapping enzyme. These structural investigations open up a new field of research, say the investigators.

Cancer treatments based on laser irridation of tiny nanoparticles that are injected directly into the cancer tumor are working and can destroy the cancer from within. Researchers have developed a method that kills cancer cells using nanoparticles and lasers. The treatment has been tested on mice…

Patients who suffer heart attacks, or flare-ups of congestive heart failure, can be cared for in a variety of hospital locations. But a new study suggests that they'll fare worse in hospitals that rely heavily on their intensive care units to care for patients like them. In fact, depending on where…

Parents are vital in encouraging their children to obey the road rules and young drivers are keen to show their parents they can be trusted, which means they may hold greater power in enforcing driver restrictions compared with traditional policing, according to new research.

A cardiac imaging study uncovers a correlation between the high prevalence of coronary artery disease in men infected with HIV and in increase in inflammatory biomarkers, report researchers.

Researchers today unveiled results from a new blood test to help identify which patients are at an elevated risk of Alzheimer's disease. The findings showed that the biochip test, which allows multiple tests to be run on one blood sample, was as accurate as existing molecular tests that analyze DNA.

New research demonstrates that a first-of-its-kind next-generation sequencing test can detect HIV drug resistance mutations that conventional tests fail to identify. This test could play a critical role in helping clinicians to optimize HIV treatment regimens, while also helping public health…

New research connects several pesticides commonly used by farmers with both allergic and non-allergic wheeze, which can be a sensitive marker for early airway problems.

As part of a phase II study, two obese patients with a rare genetic disorder were given a drug treatment to stimulate the satiety center in the brain.

A proof-of-concept study finds that the density of bones in the skull affects the size of bullet holes in the skull. The finding is useful for law enforcement officials and medical examiners seeking to identify the caliber of firearms that have been used to commit murder.

Wuerzburg neurologists have discovered an antibody that is involved in triggering certain forms of neuropathies. This discovery also allowed them to show a way to treat these diseases successfully.

Scientists have developed nanoparticles which can serve as efficient contrast agents for magnetic resonance imaging. This new type of nanoparticles produce around ten times more contrast than the actual contrast agents and are responsive to specific environments.

Hysterectomy doubles the odds of a woman enduring persistent hot flashes and night sweats, even if they retain their ovaries, new research confirms.

Having a positive attitude about aging makes older adults more resilient when faced with stressful situations, new psychology research finds.

Glucose transporters, which transfer glucose from the blood to the brain, are inhibited by E. coli K1 during bacterial meningitis, leaving insufficient fuel for immune cells to fight off infection, report researchers. Their findings may lead to a novel way of treating children with meningitis and…

Researchers have identified evidence of bacteria in sterilely obtained breast tissue and found differences between women with and without breast cancer.

The research into global concepts of selfhood, involving 73 researchers working in 35 nations, reveals that the self-beliefs of members of Western cultural groups have much more in common with the rest of the world than was previously suggested, contradicting the generally accepted view of a 'West…

Researchers have found that medium-sized HDL particles (MS-HDL-P) and the number of HDL particles (HDL-P) are better markers of coronary artery disease than high-density lipoprotein cholesterol (HDL-C). The researchers say it is possible to move past HDL-C to measures that better reflect HDL's role…

A new non-invasive PET scanning technique has been used by researchers to obtain images of neuron proliferation in the subventricular zone and subgranular zone of the hippocampal dentate gyrus. Neurogenesis in the hippocampal dentate gyrus is known to be particularly affected by depression.

The Food and Drug Administration (FDA) is advising consumers not to purchase or use Slim Fit X, a product promoted for weight loss and increasing energy. This product was identified by FDA during an examination of international mail shipments.
