In a bid to reduce waste from the harvest and export of southern rock lobsters– a multimillion dollar industry in South Australia– Australian researchers have found innovative ways of using leftover shells and parts from the processing of this premium seafood. Lobster lovers rejoice: you could soon see lobster-infused chips, dips, crackers and seasonings stocked on your supermarket shelves.
Water-filled micropores in hot rock may have acted as the nurseries in which life on Earth began. A team of scientists has shown that temperature gradients in pore systems promote the cyclical replication and emergence of nucleic acids.
The risk of extreme La Niña events in the Pacific Ocean could double because of global warming, new research has shown. The projected twofold increase in the frequency of this potentially devastating weather phenomenon across the globe could lead to increased droughts in southwestern U.S., floods in the western Pacific regions and Atlantic hurricanes.
NASA expects to save millions of dollars sending astronauts to the International Space Station, once its commercial crew program starts flying in a couple of years. SpaceX and Boeing say they are on track to carry out their first manned test flights to the space station in 2017.
Doctor after doctor said removing the tumor causing Pamela Scott's unrelenting headaches would require cutting open the top of her skull and pushing aside her brain. Then one offered a startling shortcut— operating through her eyelid. The idea: make a small incision right in the crease and sneak past the eyeball into the hard-to-reach center of the head.
The trachea is a tube that connects the upper respiratory tract to the lungs and helps carry air to the lungs. Traditional treatments for tracheal diseases usually involve removal of the affected tracheal segment. However, 3-D printing can effectively create a biodegradable tracheal segment containing a patient’s own cells for use in complex tracheal reconstruction.
Cancer uses a little-understood element of cell signaling to hijack the communication process and spread. A new computational study shows how cancer cells take advantage of the system by which cells communicate with their neighbors as they pass messages to “be like me” or “be not like me.”
Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate conditions and the ice sheet’s potentially perilous future.
The speckled object depicted here is Callisto, Jupiter’s second largest moon. Similar in appearance to a golf ball, Callisto is covered almost uniformly with pockmarks and craters across its surface, evidence of relentless collisions. In fact, Callisto is the most heavily cratered object in the Solar System.
On Jan. 27, 1970, James Schlatter, a chemist working for G.D. Searle & Company, patented an artificial sweetener as “peptide sweetening agents.” It was later named aspartame. It remains, even today, a very popular sugar substitute but is frequently vilified.
“Living-dead” bacteria exist in limbo: biologically active but not proliferating. Buried in this zombie state, disease-causing bacteria could come back from the dead to re-infect patients. Researchers have produced the first evidence of this strange phenomenon in tuberculosis, suggesting new avenues for treatment.
Private information would be much more secure if individuals moved away from cloud-based storage toward peer-to-peer systems, where data is stored in a variety of ways and across a variety of sites. By parceling and spreading data across multiple sites, and weaving it together like a tapestry, not only would our information be safer, it would be quicker to access and could potentially be stored at a lower overall cost.
Drone technology, already used in other countries, can make farmers more efficient by helping them locate problem spots in vast fields or ranchlands. Increased efficiency could mean lower costs for consumers and less impact on the environment if farmers used fewer chemicals because drones showed them exactly where to spray.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases. Never before have insects with modified DNA come so close to being set loose in a residential U.S. neighborhood.
The inaccuracy of forecasts has personal implications for people around the world, leaving them stranded without umbrellas, snowed in or stuck in airports. But considering the technology available today, why do meteorologists continue to miss the mark?
