(Phys.org)—In ytterbium nickel phosphide there is a quantum critical point between the ferromagnetic and non-magnetic states that was previously not thought possible.
'Stressed' bacteria become resistant to antibiotics
Bacteria become resistant to antibiotics when stressed, finds research published in BioMed Central's open access journal BMC Evolutionary Biology. In particular E. coli grown at high temperatures become resistant to rifampicin ...
Coldness triggers northward flight in migrating monarch butterflies, study shows
Each fall millions of monarch butterflies from across the eastern United States begin a southward migration in order to escape the frigid temperatures of their northern boundaries, traveling up to 2,000 miles ...
The heat is on
(Phys.org)—Physicists are getting warmer in the hunt for universal truths, thanks to a breakthrough by a team at the University of St Andrews.
Rethinking the process used to machine industrially important ceramics could reduce damaging cracks and chips
Ceramics are hard, chemically inert and can withstand high temperatures. These attributes make them ideal structural components in engines, high-performance disk brakes and medical implants. However, as ceramics ...
Shimmering water reveals cold volcanic vent in Antarctic waters
The location of an underwater volcanic vent, marked by a low-lying plume of shimmering water, has been revealed by scientists at the National Oceanography Centre, Southampton.
Scientists develop new materials for board-level photonics
Today at the Photonics West conference, Dow Corning and IBM scientists unveiled a major step in photonics, using a new type of polymer material to transmit light instead of electrical signals within supercomputers ...
The ecological badminton robot (w/ video)
A robot to play with! A childhood's dream has now come true for researchers at the Flanders' Mechatronics Technology Centre (FMTC) in Belgium. Wim Symens and his team pioneered the development of the first robot ever to play ...
Why NASA observes the Sun in different wavelengths
(Phys.org)—Taking a photo of the sun with a standard camera will provide a familiar image: a yellowish, featureless disk, perhaps colored a bit more red when near the horizon since the light must travel ...
Central America battles to save coffee from fungus
Central America is scrambling to contain a coffee-eating fungus that has invaded a third of the impoverished region's crops, threatening to cost the vital industry hundreds of millions of dollars.
NASA researchers studying advanced nuclear rocket technologies
(Phys.org)—Advanced propulsion researchers at NASA are a step closer to solving the challenge of safely sending human explorers to Mars and other solar system destinations.
Cluster mission indicates turbulent eddies may warm the solar wind
(Phys.org)—The sun ejects a continuous flow of electrically charged particles and magnetic fields in the form of the solar wind—and this wind is hotter than it should be. A new study of data obtained ...
Engineers seek ways to convert methane into useful chemicals
With natural gas production rising, engineers and scientists are seeking ways to convert methane into useful chemicals. A finding in Nature Chemistry suggests a pathway.
CMS observes melting of Upsilon particles in heavy-ion collisions
In 2011, CMS presented early evidence that Upsilon (Υ) particles produced in lead-lead collisions "melt" as a consequence of interacting with the hot nuclear matter created in these heavy-ion interaction ...
