Quantifying network vulnerability, and the best way to find hidden items

...ticle What is the fastest way to locate a randomly hidden object? Animals searching for food may instinctively be following the best strategy. In this paper, the authors model a search as alternating between two phases - a slow, systematic search phase during which a forager scans an area, and a fast phase ...

Photos reveal new primate species

...e wildlife research over the last century has been hidden right under our noses." The new arboreal mangabey is brown, with a head and body length of about 3 ft (90 cm). It is characterized by a long, erect crest of hair on its head, elongated cheek whiskers, an off-white belly and tail, and an unusual call...

Secret of smallpox's success may lead to bioterror cure

...from mammalian immune systems. The ability to stay hidden allows the smallpox virus, in particular, time to grow and multiply to the point of causing devastating disease before the immune system detects it and attempts to mount a counter-attack. Jacobs notes that there have been clues to this property of th...

... have set to preserving--or so they thought. But a hidden enemy is mucking up the works. Sulfur, which naturally occurs in the mud, minerals and organic matter in the ocean, is eating away at the ship's wooden elements, even as these artifacts lay safe in a conservation center in Virginia. Now, The Academy ...

Comparative chromosome study finds breakage trends, cancer ties

... at high resolution. "This study has revealed many hidden secrets on the nature and timing of genome evolution in mammals, and it demonstrates how the study of basic evolutionary processes can lead to new insights into the origin of human diseases," said Lewin, the director of the Institute for Genomic Biol...

Field of beams

... our technology, we are able to easily see what is hidden from conventional instruments," says Finkelman. "The system eliminates interference from light reflected at a leaf's surface and allows us to see light re-emitting from within." Depending on the plant, leaves reflect, transmit and absorb varying amou...

Scientists crack 40-year-old DNA puzzle and point to 'hot soup' at the origin of life

... "There are still relics of a very old simple code hidden away in our DNA and in the structures of our cells," said Dr van den Elsen, who points to several aminoacyl-tRNA synthetases - molecules involved in protein synthesis - which only look at pairs of bases in triplet codons, as well as other physical ev...

Alteration of brain protein regulates learning

...arning and memory. They were slow to learn where a hidden platform was in murky water, among other tasks, and when the electrical activity of neurons was measured in the hippocampus of these mice there was no longer any detectable reaction to reelin. Thus, the extra string of amino acids in Apoer2 seems to...

Chickens orient using a magnetic compass

...ks' direction of movement during searching for the hidden imprinting stimulus was influenced by shifting the magnetic field. One important difference between this work and earlier attempts to train birds is that the researchers used a social stimulus to train the birds, whereas most previous attempts have u...

Measuring hidden parasites in falciparum malaria

A new technique for measuring hidden malaria parasites and assessing severity of disease is described in a paper published on Aug 23rd in PLoS Medicine . Researchers led by Professor Nick White from Mahidol University, Thailand, looked at patients with the most dangerous type of malari...

New look at DNA hints at origin of ultraviolet damage

...very of the structure of DNA that kept this secret hidden for so many years, Kohler said. Their work revealed that the DNA helix was composed of paired bases, and that discovery led researchers to focus on how UV energy might interact with base pairs. "In fact, so much attention has been paid to base pairi...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...zyme wouldn't be able to reach the dimer, which is hidden inside the coiled DNA molecule, Zhong said. But electrical interactions between the DNA molecule and the enzyme cause the portion of the DNA that contains the dimer to flip outwards from the coil and into the pocket. Then, when a photon of visible li...
