Archaeologists slowly digging through a huge 2,300-year-old tomb in northern Greece have uncovered two life-sized marble female statues flanking the entrance to one of three underground chambers.
Researchers have created the world’s largest DNA origami, which are nanoscale constructions with applications ranging from biomedical research to nanoelectronics. These origami can be customized for use in everything from studying cell behavior to creating templates for the nanofabrication of electronic components.
Researchers have shown the use of sound to communicate with an artificial atom. They can thereby demonstrate phenomena from quantum physics with sound taking on the role of light.
There is hardly a spot on the planet where manmade noise doesn’t mix with— or intrude on, from another perspective— the sounds of the natural world. Eventually, one professor says, the only way people may be able to hear nature on its own terms is through an artificial digital world, much like “Star Trek.”
He's traveled to the sites of worrisome outbreaks of SARS, bird flu, MERS. But the Ebola outbreak that's spiraled out of control in West Africa presents new challenges for even a veteran infectious disease doctor— starting with how to stay safe.
The Nuclear Regulatory Commission has rejected a senior federal expert's recommendation to shut down California's last operating nuclear power plant until the agency can determine whether its twin reactors can withstand powerful shaking from nearby earthquake faults. In a decision, the agency concluded there is no immediate or significant safety concern at the Diablo Canyon plant.
Astronauts are studying how fires burn in microgravity and how to put them out. It's a basic safety issue: if a fire ever breaks out onboard a spacecraft, astronauts need to be able to control it.
Scientists have successfully reset human pluripotent stem cells to the earliest developmental state – equivalent to cells found in an embryo before it implants in the womb (seven to nine days old). These pristine stem cells may mark the true starting point for human development but have been impossible to replicate in the lab until now.
An interactive online tool allows users to calculate the value of an ecosystem, and lets them determine how altering a habitat can affect its economic, social and environmental worth.
New research findings point toward future approaches to fighting bacterial biofilms that foul everything from implantable medical devices to industrial pipes and boat propellers.
Salt crystals are often responsible when buildings start to show signs of ageing. Researchers have studied salt damage in greater depth and can now predict weathering processes more accurately.
From Apple's new smartwatch that tracks heartbeats to contact lenses that measure blood sugar— Silicon Valley is pouring billions into gadgets and apps designed to transform health care. But the tech giants that have famously disrupted so many industries are now facing their own unexpected disruption: regulation.
AB is the least common blood type, found in about 4 percent of the U.S. population. A new study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types.
Earth's protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported in a rare piece of good news about the health of the planet. Scientists said the development demonstrates that when the world comes together, it can counteract a brewing ecological crisis.
Doctors in many U.S. hospitals are unnecessarily prescribing multiple antibiotics for several days when just one would do the job. Health officials have sounded alarms that overuse of antibiotics is helping to breed dangerous bacteria that are increasingly resistant to treatment.
