Recent study suggests that introduction of meat-eating worked as a key factor in the booming population growth of humankind and ultimately its domination, Science Daily reported Friday.A high-quality diet made possible by devouring meat caused prehistoric humankind to wean faster, allowing them to be more productive, according to a research by a group of scientists from Lund University in Sweden.“Eating meat enabled the breast-feeding period and thereby the time between births to be shortened,”

A hen in Sri Lanka gave birth to a chick without an egg, veterinary officials said.(Photo courtesy of Manula Kumarage)Instead of being laid by the hen and incubated in the nest, the egg was incubated inside the hen for 21 days and then the chick hatched inside the mother.The chick is normally formed and healthy, veterinarians say, although the mother hen died.The government veterinary officer in t

Japanese researchers have successfully grown hair on hairless mice by implanting follicles created from stem cells, they announced Wednesday, sparking new hopes of a cure for baldness.This handout picture taken on April 13, 2012 and released by the Tsuji Lab Research Institute for Science and Technology of the Tokyo University of Science shows a hairless mouse with black hair on its back at the la

The fact that land-bound dinosaurs laid eggs is what sealed their fate of mass extinction millions of years ago while live birthing mammals went on to thrive, scientists said Wednesday. Chicago White Sox pitcher Mark Buerhle has a chuckle with "Baby T Rex" animated figure which threw out the first pitch before the game against the Detroit Tigers at at U.S. Cellular Field in Chicago, Illinois, Augu

If there is life on Mars it may be lurking in craters formed by asteroid impacts on the planet's surface, as has happened on Earth, Scottish scientists say.This undated image provided by NASA shows the Gale Crater on Mars. (AP-Yonhap News)Researchers at the University of Edinburgh said organisms have been found living deep beneath a site in Chesapeake Bay in the United States where an asteroid cra

A recent study by U.S. researchers suggests that intelligence may have co-evolved with worrying, Science Daily reported Thursday. Brain activity during the intellectual process involves depletion of the nutrient choline in the sub-cortical white matter, which is also true of the process of worrying, Dr. Jeremy Coplan from SUNY Downstate Medical center and his colleagues found. This suggests that excessive worrying, which is generally viewed as a negative trait may actually be a beneficial trait

LITCHFIELD, Conn. (UPI) -- Connecticut authorities said they have been unable to locate a mysterious object seen falling from the sky by witnesses including a state trooper.The Connecticut State Police said the glowing green object, which some witnesses described as being the size of a whale, was seen falling from the sky in the Litchfield area around 2 a.m. Thursday morning, and is believed to ha

(NASA/JPL/Cornell/MCT)Scientists have concluded from reviewing data of 1976 Mars Viking rovers that bacteria existed on Mars.The original consensus of scientists has been that the experiment found geological, not biologica

Scientists have succeeded in pointing out the parts of the brain that are essential for intellectual functions, the Science Daily reported Tuesday. A multi-national study found out that coordinated works of several brain areas are necessary in order to process a thought.Lead researcher Aron Barbey said the brain’s ability to add up all the information from verbal, visual, spatial and executive processes is key to intellectual function. Study showed that the brain regions involved in the thinking

U.S. researchers say a new instrument will be a "time machine" to allow scientists to study the universe's earliest galaxies that could never be studied before.(MCT)Built by researchers at UCLA, the MOSFIRE instrument -- or Multi-Object Spectrometer for Infra-Red Exploration -- has been installed in the Keck I Telescope at the W.M.
