Huge waves measured for first time in Arctic Ocean
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle ...
Mysterious molecules in space
Over the vast, empty reaches of interstellar space, countless small molecules tumble quietly though the cold vacuum. Forged in the fusion furnaces of ancient stars and ejected into space when those stars ...
'Killer sperm' prevents mating between worm species
The classic definition of a biological species is the ability to breed within its group, and the inability to breed outside it. For instance, breeding a horse and a donkey may result in a live mule offspring, ...
Connected devices have huge security holes: study
The surge Web-connected devices—TVs, refrigerators, thermostats, door locks and more—has opened up huge opportunities for cyberattacks because of weak security, researchers said Thursday.
Audi tests its A7 driverless vehicle on Florida highway
Optimum inertial self-propulsion design for snowman-like nanorobot
Scale plays a major role in locomotion. Swimming microorganisms, such as bacteria and spermatozoa, are subjected to relatively small inertial forces compared to the viscous forces exerted by the surrounding fluid. Such low-level ...
Tough foam from tiny sheets
Tough, ultralight foam of atom-thick sheets can be made to any size and shape through a chemical process invented at Rice University.
The Quantum Cheshire Cat: Can neutrons be located at a different place than their own spin?
The Cheshire Cat featured in Lewis Caroll's novel "Alice in Wonderland" is a remarkable creature: it disappears, leaving its grin behind. Can an object be separated from its properties? It is possible in ...
Alaska fisheries and communities at risk from ocean acidification
Ocean acidification is driving changes in waters vital to Alaska's valuable commercial fisheries and subsistence way of life, according to new NOAA-led research that will be published online in Progress in ...
Researchers uncover secrets of internal cell fine-tuning
New research from scientists at the University of Kent has shown for the first time how the structures inside cells are regulated – a breakthrough that could have a major impact on cancer therapy development.
Printing the metals of the future
3-D printers can create all kinds of things, from eyeglasses to implantable medical devices, straight from a computer model and without the need for molds. But for making spacecraft, engineers sometimes need ...
Getting a jump on plant-fungal interactions
Fungal plant pathogens may need more flexible genomes in order to fully benefit from associating with their hosts. Transposable elements are commonly found with genes involved in symbioses.
Stem cell advance may increase efficiency of tissue regeneration
A new stem-cell discovery might one day lead to a more streamlined process for obtaining stem cells, which in turn could be used in the development of replacement tissue for failing body parts, according ...
Great apes face extinction: conservationist Jane Goodall
The world's great apes face extinction within decades, renowned chimpanzee expert Jane Goodall warned Tuesday, in a call to arms to ensure man's closest relatives are not wiped out.
