Dinosaurs with giant domes on their heads may have used their extra padding for head butting, new research suggests.
An analysis of pachycephalosaurid skulls revealed head wounds likely incurred during combat. The pattern of wounds, described July 16 in the journal PLOS ONE, suggest the dome-headed dinos butted heads, just as bighorn sheep do today.
If you could rewind time and watch evolution take place all over again, would it happen the same way as it did before?
This question has long puzzled thinkers like legendary evolutionary scientist Stephen Jay Gould, who proposed that evolution was "utterly unpredictable and quite unrepeatable." But a new study of Caribbean lizards published today (July 18) in the journal Science suggests that, at least in some circumstances, evolution may be more predictable than previously thought.
The U.S. East Coast is sweating through a lingering heat wave this week. The sweltering heat and humidity have combined to keep temperatures hot even at night. But relief may finally be in sight.
Heat waves are marked by at least three consecutive days of temperatures of at least 90 degrees Fahrenheit (32 degrees Celsius). In New York and Boston, temperatures hit 90 degrees F or hotter Sunday through Wednesday, and are expected to do so again today (July 18). New York has already reached 96 degrees F (36 degrees C) by 1 p.m. EDT today. Baltimore reached a record high of 98 degrees F (37 degrees C) yesterday, the National Weather Service (NWS) said.
The world may be awaiting the birth of a little royal, but in the animal kingdom, it's baby panda season. Last night (July 15), a giant panda at Zoo Atlanta gave birth to two cubs, the first panda twins to be born in the United State since 1987.
The newborns are also the first pandas to be born in the country this year. They are fourth and fifth babies for 15-year-old mom Lun Lun, according to the zoo. The female last gave birth in 2010, to a male cub named Po.
The fossilized remains of a newly identified dinosaur with horns so long they would put Triceratops to shame has been discovered in the Utah desert.
The new species, described today in the journal Proceedings of the Royal Society B, was dubbed Nasutoceratops, which translates to "big-nosed horned face." The giant beast lived roughly 76 million years ago and was part of the ceratopsid group, which consists of plant-eating, rhinoceros-like dinos, including Triceratops.
Matt Howes would never have stuck his bare hand into a beehive six months ago, but since he has taken the reins of managing the four hives on the rooftop of his office, he has become more comfortable handling the honey makers.
"You become calmer, have steadier hand movements," Howes said, after adjusting an infrared camera he installed in one of his hives so that he could watch the bees from his desk, one story below.
While cloudy, gray skies blanketed parts of New York City this weekend, some lucky New Yorkers still managed to catch a glimpse of "Manhattanhenge," a…Read More »
phenomenon where the setting sun turns the city's streets into a Stonehenge-type sundial.
Manhattanhenge occurs when the sun descends in the sky perfectly in line with Manhattan's rectangular grid of streets, lighting up the north and south sides of every cross street. The pretty spectacle happens four times a year, on two sets of two consecutive days, typically in May and July.
