'4-D' Microscope Revolutionizes The Way We Look At Nano World
|
More than a century ago, the development of the earliest motion picture technology made what had been previously thought "magical" a reality: capturing and recreating the movement and dynamism of the world around us. A breakthrough technology based on new concepts has now accomplished a similar feat, but on an atomic scale by allowing, for the first time, the real-time, real-space visualization of fleeting changes in the structure and shape of matter barely a billionth of a meter in size.

Uncertainty Can Be More Stressful Than Clear Negative Feedback
|
We are faced with uncertainty every day. Will our investments pay off? Will we get the promotions we are hoping for? When faced with the unknown, most people experience some degree of anxiety and discomfort. Exactly how much anxiety someone experiences during uncertain times depends on his or her personality profile.

Beta Pictoris Planet Finally Imaged?
|
A team of French astronomers have discovered an object located very close to the star Beta Pictoris, and which apparently lies inside its disc. With a projected distance from the star of only 8 times the Earth-Sun distance, this object is most likely the giant planet suspected from the peculiar shape of the disc and the previously observed infall of comets onto the star. It would then be the first image of a planet that is as close to its host star as Saturn is to the Sun.

Simple Blood Test For Colon Cancer: New Early-warning Test Detects Polyps Before Cancer Sets In
|
Researchers in Israel have developed a simple early-warning test that can detect colon cancer in the blood. Using biomarkers, it is the first test on the market that can detect cells of colon polyps the precursors to colon cancer in the blood, with a very high degree of sensitivity and accuracy.

Male Birth Defect Associated With Certain Genetic Mutations, Study Finds
|
A small percentage of males born with cryptorchidism (failure of one or both testicles to descend into the scrotum), the most frequent congenital birth defect in male children, are more likely to have genetic mutations, including for a syndrome that is a common genetic cause of infertility, according to new study.

Quantum Computers Could Excel In Modeling Chemical Reactions
|
Quantum computers would likely outperform conventional computers in simulating chemical reactions involving more than four atoms, according to scientists. Such improved ability to model and predict complex chemical reactions could revolutionize drug design and materials science, among other fields.

Research Sheds Light On Benefits Of Multiple Mates
|
New research could explain why females of many species have multiple partners. Females of most species, including many mammals, mate with multiple partners. The driving forces for this practice, known as 'polyandry', have been a mystery for evolutionary biologists for decades. This research suggests that polyandry could be the result of females adapting to avoid producing offspring carrying selfish genetic elements that reduce male fertility.

Concealed Glaciers Discovered On Mars At Mid-latitudes
|
Vast Martian glaciers of water ice under protective blankets of rocky debris persist today at much lower latitudes than any ice previously identified on Mars, says new research using ground-penetrating radar on NASA's Mars Reconnaissance Orbiter. The discovery is an encouraging sign for scientists searching for life beyond Earth. The water ice might also provide a useful resource for human explorers visiting the red planet.

Brain Reorganizes To Adjust For Loss Of Vision
|
A new study shows that when patients with macular degeneration focus on using another part of their retina to compensate for their loss of central vision, their brain seems to compensate by reorganizing its neural connections. Age--related macular degeneration is the leading cause of blindness in the elderly. The study appears in the journal Restorative Neurology and Neuroscience.
