Scientists at the U.S. Department of Energy's Ames Laboratory are revealing the mysteries of new materials using ultra-fast laser spectroscopy, similar to high-speed photography where many quick images reveal subtle movements and changes inside the materials. Seeing these dynamics is one emerging strategy to better understanding how new materials work, so that we can use them to enable new energy technologies.
A research team at Indiana University-Purdue University Indianapolis has helped determine the science behind how canines locate explosives. The study found the dogs react best to the actual explosive, calling into question the use of products designed to mimic the odor of C-4 for training purposes.
The ability to duplicate an experiment and its results is a central tenet of the scientific method, but recent research has shown an alarming number of peer-reviewed papers are irreproducible. A team of math and statistics professors has proposed a way to address one root of that problem by teaching reproducibility to aspiring scientists, using software that makes the concept feel logical rather than cumbersome.
University of Waterloo physicists have succeeded in measuring how the surfaces of glassy materials flow like a liquid, even when they should be solid. A series of simple and elegant experiments were the solution to a problem that has been plaguing condensed matter physicists for the past 20 years.
Researchers from ETH Zurich and the University of Tubingen describe a process that suppresses the formation of methane in soils that are rich in humic substances. For this process to work, the soils need to switch between having no oxygen and having oxygen.
For people whose hands shake uncontrollably due to a medical condition, just eating can be a frustrating and embarrassing ordeal – enough to keep them from sharing a meal with others. But a small new study conducted at the University of Michigan Health System suggests that a new handheld electronic device can help such patients overcome the hand shakes caused by essential tremor, the most common movement disorder.
NASA's aerospace industry partners continue to meet milestones under agreements with the agency's Commercial Crew Program (CCP), as they move forward in their development of spacecraft and rockets that will transport humans to destinations in low-Earth orbit.
In his PhD thesis, the Industrial Engineer Daniel Salcedo-Perez has studied the process to forge mechanical components using nanostructured material. Specifically, he has been able to produce matrices to forge a set of mechanical parts like cogs and gears. “These functional nanostructured components have been produced free of faults, and this is something that had not been done previously," he pointed out.
An international team of scientists led by physicists from the University of York has paved the way for a new class of magnetic materials and devices with improved performance and power efficiency. Magnetic materials are currently used to store digital information.
Real-time social media like Twitter could be used to track HIV incidence and drug-related behaviors with the aim of detecting and potentially preventing outbreaks, a new UCLA-led study shows. The study, published in Preventive Medicine, suggests it may be possible to predict sexual risk....
A new web portal – called PhenomeCentral – is being launched today to connect clinicians and scientists worldwide in an effort to speed the discovery of genes responsible for rare disorders. More than 350 million people suffer from over 7,000 rare diseases worldwide....
Astronauts floating weightlessly in the International Space Station may appear carefree, but years of research have shown that microgravity causes changes to the human body. Spaceflight also means exposure to more radiation. Together, microgravity and radiation exposure add up to pose serious health risks. But research is not only making space safer for astronauts, it's helping to improve health care for the Earth-bound as well.
The sun emitted a significant solar flare, peaking at 7:49 p.m. EST on Feb. 24, 2014. NASA's Solar Dynamics Observatory, which keeps a constant watch on the sun, captured images of the event. Solar flares are powerful bursts of radiation, appearing as giant flashes of light in the SDO images. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however...
A new report appearing in the March 2014 issue of The FASEB Journal helps shed light on what drives the evolution of pathogens, as well as how our bodies adapt to ward them off. Specifically, the report shows that our bodies naturally employ a mechanism, called "CD33rSiglecs," that not only dampens unwanted immune responses against one's own cells, but also evolves rapidly to recognize foreign invaders.
Instruments strapped onto and ingested by sharks are revealing novel insights into how one of the most feared and least understood ocean predators swims, eats and lives. Researchers at the University of Hawaii and the University of Tokyo outfitted sharks with sophisticated sensors and video recorders to measure and see where they are going, how they are getting there, and what they are doing once they reach their destinations.
