Professor Dongsoo Har and his team in Cho Chun Shik Graduate School of Green Transportation in Korea Advanced Institute of Science and Technology (KAIST) lately developed an aerial vehicle that is able to control the main wings separately and independently.
In 2004, a tsunami devastated much of the Indonesian city of Banda Aceh. An international team of researchers has studied the long-term impact that rebuilding efforts in coastal areas have had on the community.
A new study strongly suggests that the brains of people who have died of Huntington's disease (HD) and Parkinson's disease (PD) show a similar response to a lifetime of neurodegeneration, despite being two very distinct diseases.
Water contaminated by the oil currently leaking into the ocean from the Sanchi tanker collision is likely to take at least three months to reach land, and if it does the Korean coast is the most likely location. However, the oil’s fate is highly uncertain, as it may burn, evaporate, or mix into the surface ocean and contaminate the environment for an extended duration.
In a paper published in the journal Physical Review E, a duo of fluid dynamics experts proposes a solution to one of long-standing Martian mysteries. The research shows that wind vortices can produce the common Martian phenomenon of a stratified mound positioned downwind from the center of an ancient meteorite impact zone. Mars’ Gale Crater, [...]
By combining the visible and infrared capabilities of NASA’s Spitzer and NASA/ESA Hubble space telescopes, a team of specialists at NASA’s Universe of Learning program has created a spectacular, three-dimensional, fly-through movie of the famous Orion Nebula, a diffuse nebula in the constellation Orion. The Orion Nebula can be seen with the naked eye as [...]
Scientists have characterized a protein that enables certain microorganisms to recognize and absorb ammonium in their environment. Ammonium is considered a toxin that pollutes ecosystems - but for these bacteria it represents an important nutrient and energy source.
Bioengineers have developed a tissue-based soft robot that mimics the biomechanics of a stingray. The new technology could lead to advances in bio-inspired robotics, regenerative medicine and medical diagnostics.
In a technology first, a team of engineers has demonstrated fully autonomous X-ray navigation in space -- a capability that could revolutionize NASA's ability in the future to pilot robotic spacecraft to the far reaches of the solar system and beyond.
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets.
Neuroscientists have found that even a brief episode of immune system activation within days of birth can cause persistent changes in sleep patterns concurrent with increases in epilepsy-like brain activity -- a combination of symptoms common in autism spectrum disorder (ASD) and other developmental conditions.
Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, researchers systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.
A group of researchers specializing in quantum calculations has proposed a radically new computational approach to solving the complex many-particle Schrödinger equation, which holds the key to explaining the motion of electrons in atoms and molecules.
Researchers have succeeded in the localized cooling of the heart during a heart attack, a world first. By cooling part of the heart prior to and following angioplasty, the cardiologists believe that the damage from a heart attack can be limited.
Microscopic yeast have been wreaking havoc in hospitals around the world -- creeping into catheters, ventilator tubes, and IV lines -- and causing deadly invasive infection. One culprit species, Candida auris, is resistant to many antifungals, meaning once a person is infected, there are limited treatment options. But researchers have now confirmed a new drug compound kills drug-resistant C. auris, both in the laboratory and in a mouse model that mimics human infection.
