Roosters ‘tell time’ in to begin crowing
NAGOYA, Japan -- Roosters crowing at dawn aren‘t just reacting to the external stimulus of light, Japanese researchers say; they actually know what time of day it is.In a study reported in the journal Current Biology, scientists at Nagoya University say there is indeed a clock in “cock-a-doodle-doo” -- a biological one.“’Cock-a-doodle-doo‘ symbolizes the break of dawn in many countries,” researcher Takashi Yoshimura said. “But it wasn’t clear whether crowing is under the control of a biological

Should doctors listen to music while operating?
In last year’s smash hit TV series “Best Love,” the lead actor confirmed his love for a woman by recalling the melody he had heard during his surgery. A very romantic scene to watch, for sure. However, if it were your operation, would you allow your surgeon to enjoy listening to music while doing a very delicate operation?It’d be better to let them enjoy the music, as one recent study revealed that listening or humming to one’s favorite music helps doctors to work more effectively. The study, pu

THX, founded by George Lucas, sues Apple in patent case
Apple Inc. (AAPL) was accused by THX Ltd., a company founded by “Star Wars” producer George Lucas, of stealing speaker technology used in iPhones, iPads and iMac products. THX holds a 2008 patent for a speaker unit that can boost sound output and attach to computers or flat-screen televisions, according to a complaint filed yesterday in federal court in San Jose, California. Apple products that incorporate the speaker units infringe the THX patent, causing the company “monetary damage and irrepa

Doctors against prescribing 'study drugs'
Prescribing drugs to boost memory and thinking abilities in healthy children and teens to study is misguided, U.S. researchers say. Study author Dr. William Graf of Yale University in New Haven, Conn., said some parents request doctors to prescribe attention-deficit hyperactivity disorder drugs for their children who don't meet the criteria for ADHD, to help them study for tests."Doctors caring for children and teens have a professional obligation to always protect the best interests of the chi

Chinese zoo shows pandas ‘porn’ to get them mating
A Chinese zoo recently tried an unusual method to encourage its giant pandas to mate: showing them a panda version of a porn video.The zoo -- which is located in Chengdu -- managed to get the pandas to mate after showing them a video of other panda’s copulating, according to the English edition of Chinese daily Global Times.Zoo officials said every time male panda Yongyong tried to mate with his companion KeLin, she would fight him off. Since the mating period for a panda is relatively short, Ke

Study: Early birds possibly had four wings
Early birds evolved from feathered dinosaurs with four wings but soon ditched "training wheels" for more efficient two-winged flight, Chinese scientists say.In 2003, a group of Chinese researchers excavated six fossils of flying dinosaurs with wings on their hind legs, dubbing them Microraptors."When we published that ten years ago there was some suspicion whether the fossil was faked," Xing Xu from Linyi University in Shandong province said.Now Xu and colleagues have described another find supp

Answering messages while driving like DUI
Using a hands-free kit on a cellphone or texting affected driving as much as being above the legal alcohol limit, Australian and Spanish researchers say.

Study co-author Sumie Leung Shuk Man of the University of Barcelona said the drivers took the test having consumed alcohol, and then usin

Taking care of your lungs
I feel that more people are becoming worried about lung cancer these days. I have had students in their 20s come in with chest pain, who were found to have normal lungs, but insisted on a full check up because their uncle died of lung cancer. Of course, lung cancer can cause chest pain. This does not mean that all chest pain is caused by lung cancer. Many patients, on the other hand, can be diagnosed with lung cancer even without any symptoms.Get tested if you see blood in your phlegmThere are s

Dental microscopes boost quality of treatment
High-performance microscopes are powerful tools in dental treatment, but only a handful of university hospitals and professional clinics possess such equipment.These microscopes magnify the treatment area by 10 to 26 times, which allows dentists to detect miniscule cracks and nerve damage in the teeth that are invisible to the naked eye. In the past, it was difficult to detect the precise location of infection, and thus dentists frequently removed healthy teeth surrounding the infection point as

ITC delays Samsung-Apple decision again
A U.S. trade agency has once again delayed its decision on the high-profile patent war between Apple and Samsung, this time based on considerations of how much consumers and the U.S. economy would be hurt should it ban imports of Apple’s iPhones and iPads over a patent held by Samsung Electronics. The U.S. International Trade Commission in Washington was scheduled to issue a final decision in Samsung’s patent infringement case yesterday. Instead, it asked for comments on how a ban would affect t

Men and women smoke for different reasons

Neanderthal demise down to eye size?
Neanderthals went extinct because they had larger eyes than modern humans that monopolized brain resources to see in the long nights in Europe, scientists say.Modern humans, on the other hand, spent more time in Africa where longer, brighter days required no such adaption and allowed our frontal lobes, associated with higher-level thinking, to evolve further before we moved out of Africa and spread across the globe, they said.Eiluned Pearce of Britain's Oxford University, comparing Neanderthal s
