Mimicking how the brain recognizes street scenes

...particular object that is very specific, such as a horse as opposed to a cow or a unicorn. At the same time the representation must be sufficiently "invariant" so as to discard meaningless changes in pose, illumination, size, position, and many other variations in appearances.

Trojan horse strategy defeats drug-resistant bacteria

...ery similar to iron. "Gallium acts as a Trojan horse to iron-seeking bacteria," said Singh. "Because gallium looks like iron, invading bacteria are tricked, in a way, into taking it up. Unfortunately for the bacteria, gallium can't function like iron once it's inside bacterial cells." The research...

ASU researchers test antibacterial effects of healing clays

...edies, such as dandelion, green tea, valerian, and horse chestnut, and practices like acupuncture, Tai Chi, and Reiki that fall outside conventional medicines. The ASU duo will examine the mechanisms that allow two clays mined in France to heal Buruli ulcer, a flesh-eating bacterial disease found primar...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

... chicken for weeks. Flu is a major problem in the horse racing industry and in domestic horses. It also has very recently become a problem in domestic dogs in the USA and domestic cats are susceptible to H5N1 virus. The Warwick research team has now filed a patent on the protecting virus and they are e...

Geneticists discover genes that make fruit fly hybrids sterile

...For example, a mule, the result of the mating of a horse and a donkey, is sterile. Now, Cornell researchers have made the first identification of a pair of genes in any species that are responsible for problems unique to hybrids. Specifically, the researchers have found two genes from two fruit fly specie...

Man may have caused pre-historic extinctions

...ss of fossil records mean that the survival of the horse beyond the arrival of humans cannot be ruled out. The PNAS paper develops a new statistical method to help resolve the inherent problems associated with dating fossils from the Pleistocene period. The aim is to provide a far more accurate timetable ...

NHGRI announces latest sequencing targets

... NHGRI has recently approved the sequencing of the horse (Equus caballus) to high-density genome coverage. A set of five fungi known as dermatophytes, which are the most common sources of human fungal disease, will also have their genomes sequenced. Dermatophyte fungi are highly communicable and infect m...

Widespread elephant slaughter discovered in Chad

Wisconsin scientists find a way to make human collagen in the lab

...Catgut, the biodegradable sutures made from cow or horse intestines and used in surgery to minimize scarring, is also a form of collagen. But for such a commonplace and useful protein, collagen has defied the efforts of biomedical researchers who have tried mightily to synthesize it for use in application...

Bringing the zoos to the zebras
