The whirring sound of Hyperloop UC's hover engines filled the conference room as an anxious crowd shuffled closer for a better view. Would this student-designed prototype actually levitate? The answer came in a matter of moments as the eight miniature engines gained revolutions per minute -- emitting noises reminiscent of Star Wars sound effects -- and the 14-foot-long Hyperloop UC pod achieved roughly a quarter-inch of magnetic levitation.
Populations of coral reef fish in shallower, more vulnerable habitats likely owe at least some of their sustainability to the prodigious reproductive abilities of large, old counterparts that dwell at greater depths, a recent study suggests.
Creating a 3-D replica of someone's hand complete with all five fingerprints and breaking into a secure vault sounds like a plot from a James Bond movie. But researchers recently discovered this may not be as far-fetched as once thought and wants security companies and the public to be aware.
Transforming data about the structure of proteins into melodies gives scientists a completely new way of analyzing the molecules that could reveal new insights into how they work -- by listening to them. A new study shows how musical sounds can help scientists analyze data using their ears instead of their eyes.
An anonymous reader writes: Europe's Schiaparelli lander did not behave as expected as it headed down to the surface of Mars on Wednesday. Telemetry data recovered from the probe during its descent indicates that its parachute was jettisoned too early. The rockets it was supposed to use to bring itself to a standstill just above the ground also appeared to fire for too short a time. The European Space Agency (Esa) has not yet conceded that the lander crashed but the mood is not positive. Experts will continue to analyse the data and they may also try to call out to Schiaparelli in the blind hope that it is actually sitting on the Red Planet intact. In addition, the Americans will use one of their satellites at Mars to image the targeted landing zone to see if they can detect any hardware. Although, the chances are slim because the probe is small. For the moment, all Esa has to work with is the relatively large volume of engineering data Schiaparelli managed to transmit back to the "mothership" that dropped it off at Mars - the Trace Gas Orbiter.
Biologists who study the mechanics of cell division have for years disagreed about how much force is at work when the cell's molecular engines are lining chromosomes up in the cell, preparing to winch copies to opposite poles across a bridge-like structure called the kinetochore to form two new cells. The question is fundamental to understanding how cells divide, says a cell biologist.
Bolivian glaciers shrunk by 43% between 1986 and 2014, and will continue to diminish if temperatures in the region continue to increase. Glacier recession is leaving lakes that could burst and wash away villages or infrastructure downstream, warns one expert.
Finding meaning outside of work and proactively tailoring duties on the job may help people who fail to gel with a company's culture stay engaged and become more productive workers, according to researchers.
Eukaryotic cells, including human cells, form paired condensed chromosomes before cell division. The paired chromosomes are then equally divided into the daughter cells. Prokaryotic cells, including bacteria, do not have such a DNA distribution system. Researchers have discovered that the photosynthetic cyanobacterium Synechococcus elongatus shows eukaryotic condensed chromosome-like DNA compaction prior to cell division and were able to reveal details of the transiently formed structure.
Researcher pored through more than 10 years of existing Chandra X-ray Observatory data and found stars that repeatedly survive quick, massive surges in space energy. There are no such instances in our galaxy, as stars are destroyed by similar conditions.
New insight about how cells dispose of their waste has been discovered by researchers. They show the necessity of a regulation in space and time of a key protein involved in cellular waste disposal. Dysfunctions in the waste disposal system of a cell are linked to cancer and Alzheimer’s disease.
A potential new strategy may be utilized to correct hypospadias, a birth defect which occurs when boys are born with a urinary opening on the underside of the penis, found in up to one in every 200 boys. Current treatment involves surgical reconstruction with a graft using tissue taken from the inside of a child’s cheek. This approach is associated with multiple complications and sometimes requires repeated surgeries.
Doctors are more likely to prescribe growth hormones for a child who does not meet federal guidelines for the therapy if the child’s family requests it or if the physician believes in its intangible benefits, such as the patient’s emotional well-being, new research finds.
A study into freshwater lake management along the Amazon’s most meandering river has demonstrated astounding benefits to local livelihoods in replenishing vitally important fish stocks — a source of much-needed food and income.
