Only slightly more likely to attract fetishists. Researchers at the University of Liverpool studies more than 25,000 steps made on a pressure-sensitive treadmill at the University's Gait Lab. The results indicate that our feet are not the wonderful mechanisms of human genetic superiority but are closer those of great apes, the other humanoids on the planet.
Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated with nanoscale structures.
One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.
Scientists have harnessed the tools needed to stage Earth’s most colorful light show, and they have brought the Aurora Borealis into a lab at NASA’s Langley Research Center in Hampton, Va.
University of Warwick scientists have shown how to tie knots in liquid crystals using a miniature Möbius strip made from silica particles.
The use of LSD, magic mushrooms, or peyote does not increase a person's risk of developing mental health problems, according to an analysis of information from more than 130,000 randomly chosen people, including 22,000 people who had used psychedelics at least once.
Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km long billowing from hydrothermal vents in the South Atlantic Ocean. The finding, soon to be published in the journal Nature Geoscience, calls past estimates of iron abundances into question, and may challenge researchers’ assumptions about iron sources in the world’s seas.
It is unclear what the impact will be on the climate, but three and half hours after the initial explosion, NASA's ozone-mapping satellite detected the plume at 25 miles altitude above the earth's surface moving at about 190 mph eastward.

Analysis of an ice core taken by the National Science Foundation- (NSF) funded West Antarctic Ice Sheet (WAIS) Divide drilling project reveals that warming in Antarctica began about 22,000 years ago, a few thousand years earlier than suggested by previous records.
Limited availability of fossil fuels stimulates the search for different energy resources. The use of biofuels is one of the alternatives. Sugars derived from the grain of agricultural crops can be used to produce biofuel but these crops occupy fertile soils needed for food and feed production.
The ability to control nanoscale imperfections in superconducting wires results in materials with unparalleled and customized performance, according to a new study from the Department of Energy’s Oak Ridge National Laboratory.
MIT researchers have engineered a new rechargeable flow battery that doesn't rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.
ETH-researchers cannot "beam" objects or humans of flesh and blood through space yet, a feat sometimes alluded to in science fiction movies. They managed, however, to teleport information from A to B – for the first time in an electronic circuit, similar to a computer chip.
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a new material to make smart windows even smarter. The material is a thin coating of nanocrystals embedded in glass that can dynamically modify sunlight as it passes through a window.
Memory devices like disk drives, flash drives and RAM play an important role in our lives. They are an essential component of our computers, phones, electronic appliances and cars.
As the day to the beginning of the World Solar Challenge this October draws near, an increasing number of college teams competing in the 3000 km (1864 mile) race across Australia are unveiling their entries.
Light traveling in a vacuum is the Universe’s ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed bump in light’s path.
A team at the University of California, Riverside Bourns College of Engineering has developed a novel way to build what many see as the next generation memory storage devices for portable electronic devices including smart phones, tablets, laptops and digital cameras.
Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. In a paper published this week in Optics Letters, they describe how they used a laser to trap nanodiamonds in space, and – using another laser – caused the diamonds to emit light at given frequencies.
Climate change alters the way in which species interact with one another--a reality that applies not just to today or to the future, but also to the past, according to a paper published by a team of researchers in this week's issue of the journal Science.
