In August 2011, thousands of dead red abalone washed up on the beaches of Sonoma County in Northern California. At the time, the cause was unknown. Now, scientists, using a new approach called forensic genomics, have learned that a harmful algal bloom was to blame: the causative agent Yessotoxin.
Investigators have been analyzing data collected by a robotic submarine that completed its first successful scan of the seabed Thursday in the hunt for the missing Malaysian plane. The tests have ruled out that a nearby oil slick came from the aircraft.
An associate professor of media arts and sciences gets about 100 emails daily from people across the world interested in his bionic limbs. He designs— and wears— bionic leg prostheses that he says, “emulate nature,” by mimicking the functions and power of biological knees, ankles and calves.
In the midst of the diabetes epidemic, a glimmer of good news: heart attacks, strokes and other complications from the disease are plummeting.
Portland officials say they are flushing away millions of gallons of treated water, for the second time in less than three years, because someone urinated into a city reservoir.
An escape route mapping system, based on the behavior of ant colonies, could give evacuees a better chance of reaching safe harbor after a natural disaster or terrorist attack. The system builds a map showing the shortest routes to shelters, and provides regular updates of current situations such as fires, blocked roads or other damage via smartphones.
Researchers have found that environmental stressors– from the Trail of Tears to the Civil War– led to significant changes in the shape of skulls in the eastern and western bands of the Cherokee people. The findings highlight the role of environmental factors in shaping our physical characteristics.
Researchers have identified a new syndrome called "osteosarcopenic obesity" that links the deterioration of bone density and muscle mass with obesity.
Positron emission tomography, which looks at energy uptake in different parts of the brain, could be particularly good at determining more accurately which people in a minimally conscious state or suffering from unresponsive wakefulness syndrome might regain consciousness.
Geologists who analyzed 40 meteorites that fell to Earth from Mars have unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6-billion-year evolution of our solar system.
A new technique has revealed the motion of energy-carrying quasiparticles, called excitons, in solid material for the first time.
A new design for nuclear plants built on floating platforms, modeled after those used for offshore oil drilling, could help avoid disasters in the future. Such floating plants would be designed to be automatically cooled by the surrounding seawater in a worst-case scenario, which would indefinitely prevent any melting of fuel rods, or escape of radioactive material.
Verano-Braga and a team from the Univ. of Southern Denmark discovered that nanosilver can penetrate our cells and cause damage.
On the scale of earth-friendly materials, you’d be hard pressed to find two that are farther apart than polyester and cork. In an unexpected twist, however, scientists are figuring out how to extract a natural, waterproof, antibacterial version of the former from the latter.
