Forensic experts began excavating graves and examining bones this weekend in a tiny chapel in Madrid, hoping to solve the centuries-old mystery of exactly where the great Spanish writer Miguel de Cervantes was laid to rest. The author of "Don Quixote" was buried in 1616 at the Convent of the Barefoot Trinitarians in Madrid's historic Barrio de las Letras, but the exact whereabouts of his grave within the convent chapel are unknown.
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 south-western 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 that 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, a chemist working for G.D. Searle & Company, named James Schlatter, 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?
It’s great that it’s so easy to keep in contact with close friends and family, almost anywhere in the world. Yet, at a time when we are battling to keep carbon emissions under control, can we really justify the energy consumption involved in streaming cat videos in ever-higher definition?
The World Health Organization has proposed reforms that could overhaul its structure after botching the response to the biggest-ever Ebola outbreak, a sluggish performance that experts say cost thousands of lives. Several dozen of WHO's member countries have approved a resolution aimed at strengthening the U.N. health agency's ability to respond to emergencies.
