The invention of the laser -- more than 50 years ago -- that has turned up in everything from Compact Discs to laser pointers, now has a new enemy: the "antilaser" -- the first device capable of trapping and terminating laser beams. The device was created by a team of researchers from Yale University and is capable of absorbing an incoming laser beam entirely. But the antilaser was not developed as a defense against high-power laser weapons, said the researchers. While such a device seems...

While enthusiasts across the world pored over the Voynich manuscript, penned by an unknown author in a language no one understands, a research team at the University of Arizona solved one of its biggest mysteries: When was the book made? University of Arizona researchers have cracked one of the puzzles surrounding what has been called "the world's most mysterious manuscript" "“ the Voynich manuscript, a book filled with drawings and writings nobody has been able to make sense of to this...

The potentially deadly bacterium Salmonella possesses a molecular machine that marshals the proteins it needs to hijack cellular mechanisms and infect millions worldwide. In a paper published Feb. 3 online in Science Express, Yale University researchers describe in detail how Salmonella, a major cause of food poisoning and typhoid fever, is able to make these proteins line in up in just the right sequence to invade host cells. "These mechanisms present us with novel targets that might form...

A team of Yale University scientists has synthesized for the first time a chemical compound called lomaiviticin aglycon, leading to the development of a new class of molecules that appear to target and destroy cancer stem cells. Chemists worldwide have been interested in lomaiviticin's potential anticancer properties since its discovery in 2001. But so far, they have been unable to obtain significant quantities of the compound, which is produced by a rare marine bacterium that cannot be...

A new study published Thursday in the journal Science has found that female butterflies that grow up in colder temperatures become more aggressive as adults, actively chasing males for sex and food. "Behavior in these butterflies is changed by the temperatures experienced during development," said study co-author Kathleen Prudic of Yale University, who studied female Squinting Bush Brown Butterflies (Bicyclus anynana). Researchers were curious as to why some females had ornate wing markings...

Scientists suggest that an extinct flightless bird from Jamaica fought rivals and predators using wings which evolved into clubs. The boney bludgeons the bird carried are unlike anything else known in the bird world. The scientists report finding bones that had apparently been broken by another bird's club. The species may have survived until less than 10,000 years ago. The bird was probably about the size of a chicken, but with an infinitely more robust armory. Fossils show that the...

Researchers reported on Monday that expanding screening for the AIDS virus to include every American at least once and the highest-risk people once a year could prevent over 80,000 infections over the next 20 years. The team at Yale University and Stanford University in California reported that if treatment for infected people were integrated into a program like this then it would prevent about 212,000 new infections. The U.S. Centers for Disease Control and Prevention (CDC) recommends...

A Yale University study has determined that kids who start the day with a bowl of sugary cereal are consuming almost twice the sugar they would take in eating healthier options. Kids served sugary cereal consumed over 24 grams of refined sugar.  Those given low-sugar cereals were more likely to reach for table sugar, but still consumed about half the amount of sugar overall. The kids who ate either sugary or low-sugar cereals during the study were equally likely to say they enjoyed...

Yale University researchers have found that a single molecule not only connects brain cells but also changes how we learn. The findings, reported in the December 9 issue of the journal Neuron, may help researchers discover ways to improve memory and could lead to new therapies to correct neurological disorders. The junctions between brain cells over which nerve pulses pass "” called synapses "” are crucial for regulating learning and memory and how we think. Aberrations in the...

Lesbian, gay and bisexual (LGB) adolescents are about 40 percent more likely than other teens to be punished by school authorities, police and the courts, according to a study by Yale University researchers. Published in the January 2011 issue of the journal Pediatrics, the study is the first to document excessive punishment of LGB youth nationwide. "We found that virtually all types of punishment"”including school expulsions, arrests, juvenile convictions, adult convictions and...
