Red blood cells must be flexible to squeeze through tiny capillaries to deliver oxygen. Chemists have now discovered the secret of this flexibility: a 2-D triangular mesh, like a geodesic dome, underlies the membrane, ea...

Current computer systems represent bits of information, the 1's and 0's of binary code, with electricity. Circuit elements, such as transistors, operate on these electric signals, producing outputs that are dependent on ...

An amateur astronomer appears to have made contact with the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite, which lost contact with NASA in 2005.

A new study in mice suggests that a burst of dopamine levels at the beginning of a movement only, as opposed to all the time, is what gets us going. This may have important implications for treating Parkinson's disease.

Thirty years ago it was rare for a student with ASD to enter college. But over the past decades, there has been much improvement in the detection and awareness of ASD in children. Now, with the provision of effective tre...

A research team led by physicists at LMU Munich reports a significant advance in laser-driven particle acceleration. Using tiny plastic beads as targets, they have produced proton bunches that possess unique features, op...

Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms. Now in a new study, r...

Pregnant mothers aged 40 and over may have an increased risk for preterm birth, regardless of confounding factors, according to a new study.

Researchers studied blood samples taken from patients diagnosed with sepsis and found that elevated chlorinated lipids predicted whether a patient would go on to suffer acute respiratory distress symptom (ARDS) and die w...

Researchers found human papilloma virus (HPV), the culprit behind cervical and head and neck cancers, hiding in small pockets on the surface of tonsils. They believe HPV may evade the immune system in this hiding place, ...

Researchers have discovered that the training, designed to help individuals with SCI improve motor function, also leads to improved bladder and bowel function and increased sexual desire.

Searching for clues to complex social behaviors, experiments found that laboratory rats - much like humans - will approach distressed juveniles but avoid distressed adults -- responses known as social affective behaviors...

A team of researchers has advanced the scientific understanding of abnormal mineral accumulation in arteries, a complication often seen in patients with chronic kidney disease and diabetes. Mineralized arteries may affec...

Trimming the whiskers of mice suggests that blocking off some functions of the brain can help it rewire itself around stroke damage, speeding up recovery

The bacteria that cause Lyme disease are transmitted to humans primarily by the blacklegged tick (Ixodes scapularis). Often presumed guilty by association is the lone star tick (Amblyomma americanum). However, a new revi...

Although tobacco control measures have reduced overall smoking rates in the United States, a new report says several vulnerable subpopulations continue to smoke at high rates.

Researchers have identified cells in the brains of mice that indicate when the animal is anxious.

Scientists have discovered that DNA contains a kind of built-in timer that clocks the frequency with which mutations occur. They show that DNA bases can shape-shift for a thousandth of a second, transiently morphing into...

Researchers have identified features of the influenza virus genome that affect how well the virus multiplies. These features are similar but not identical across viral strains. It's possible that the extent of similarity...

Deaths caused by accidental drug overdoses in the US now exceed those from motor vehicle incidents and guns. The government has been all talk and little action

A cache of stone tools found in south India reveals that the hominins living there over 170,000 years ago already had advanced tool-making skills

Sleep deprivation appears to be more detrimental to working memory in females, a new study reports.
