A novel study of a Tibetan alpine meadow has shown a clear link between higher biodiversity and greater infectious disease resistance.
Police view blacks as 'suspects first, civilians second'

Most of the Ferguson protestors believed police view black people as worthless thugs and white people as innocent and superior - perceptions that, true or not, affect police-community relations in an era of persistent racial strife.

Researchers have discovered a 'bizarre' microorganism which plays a key role in the food web of Earth's oceans.
Genomes of chimpanzee parasite species reveal evolution of human malaria
Phys.org - latest science and technology news stories - Hace 5 horas
Understanding the origins of emerging diseases - as well as more established disease agents—is critical to gauge future human infection risks and find new treatment and prevention approaches. This holds true for malaria, which kills more than 500,000 people a year. Symptoms, including severe anemia, pregnancy-associated malaria, and cerebral malaria, have been linked to the parasite's ability to cause infected red blood cells to bind to the inner lining of blood vessels.
7 places that scientists are searching for new drugs
Phys.org - latest science and technology news stories - Hace 5 horas
Many of the drugs we use in hospitals – antibiotics, antifungals and anti-cancer drugs, to name but a few – are produced by bacteria that live in the soil beneath our feet. Most of the antibiotics we use were discovered by scientists in the mid-20th century, but as the threat of drug resistant infections increases, the race is on to find new microbes that make new drugs. Scientists have only identified a tiny fraction of the microbes living on Earth and are looking for useful new ones in wildly different locations, known as 'bioprospecting'.
Solid electrolytes open doors to solid-state batteries
Phys.org - latest science and technology news stories - Hace 5 horas
Japanese scientists have synthesized two crystal materials that show great promise as solid electrolytes. All-solid-state batteries built using the solid electrolytes exhibit excellent properties, including high power and high energy densities, and could be used in long-distance electric vehicles.
How infrared light can be captured by graphene nanostructures
Phys.org - latest science and technology news stories - Hace 5 horas
Researchers from CIC nanoGUNE, in collaboration with ICFO and Graphenea, have demonstrated how infrared light can be captured by nanostructures made of graphene. This happens when light couples to charge oscillations in the graphene. The resulting mixture of light and charge oscillations, called plasmon, can be squeezed into record-small volumes millions of times smaller than in conventional dielectric optical cavities. This process has been visualized by the researchers for the first time with the help of a state-of the-art, near-field microscope and explained by theory. The resear... más »
