Democratic Rep. Beto O’Rourke has repeated his previous assertions that he would vote to impeach President Donald Trump — an aggressive position that may be a tough sell as he tries to win a Senate seat in deep-red Texas.
TACOMA, Wash. (AP) — Calls to breach four hydroelectric dams in Washington state have grown louder in recent months as the plight of critically endangered Northwest orcas has captured global attention.
Running into a Tyrannosaurus rex in the wild would have been a truly frightening thing for just about any animal that roamed the earth between 65 million and 80 million years ago, and for an obvious reason. The mighty meat-eater was huge in size and had a mouth built to turn bones into powder. If it snagged you with its jaws you were probably going to have a bad time, but nobody was afraid of its puny little arms... or were they?
As Live Science reports, a new study presented at a recent meeting of the Society of Vertebrate Paleontology took a close look at how T. rex's arms would have functioned, and it makes some bold predictions.
Just how T. rex used its arms and for what purpose has been hotly debated for years and years. Some believe the arms didn't do much of anything, while others have suggested that the tiny limbs flailed wildly with sharp claws that could have seriously injured prey or foes.
This latest round of research approaches things from a different angle, seeking to determine the range of movement of the arms as a clue to their usefulness. The researchers studied the limbs of two distant modern relatives, the alligator and turkey, for hints. What the team concluded is that the T. rex could likely have turned its hands inward if it wanted to, and it may have used its arms to hold prey in place or pull it closer.
The idea here is that the T. rex knew its jaws were its most potent weapon and so it used its arms to keep prey at the perfect biting distance. We'll of course never know for sure unless we could somehow watch a T. rex or similar upright carnivore find a meal, but the researchers are confident in what the fossils and modern animals tell them about how the dinosaur could move its limbs.
Prior to his death on Monday, billionaire Microsoft co-founder Paul Allen invested large sums in technology ventures, research projects and philanthropy, some of it eclectic and highly speculative. Outside of bland assurances from his investment company, no one seems quite sure. Allen died in Seattle from complications of non-Hodgkin's lymphoma, according to his company Vulcan Inc. He was 65.
TORONTO/LONDON (Reuters) - Anglo American unit De Beers is going after lucrative, but elusive high-tech markets in quantum computing, as it aims to expand its lab-grown diamond business beyond drilling and cutting. Element Six, De Beers' synthetic diamond arm, is building a $94 million factory in Portland, Oregon, an expansion that comes as scientists from Moscow to London push to develop diamonds for futuristic applications. Now coming of age after decades of experiments, technology called chemical vapor deposition, or CVD, offers a path to higher-quality, lower-cost production of synthetic diamonds and that opens the door to potential new computing markets.
Scientists said on Thursday they have unearthed in southern Germany the fossil of a fish that, with its mouth full of razor-sharp teeth, strongly resembled today's piranhas, the stars of more than their fair share of Hollywood horror films. Named Piranhamesodon pinnatomus, it is the earliest known example of a bony fish - as opposed to cartilaginous fish like sharks - able to slice flesh rather than simply swallowing prey, enabling it to attack victims larger than itself as piranhas can. Piranhas are freshwater fish that inhabit rivers and lakes in South America.
The Moon is great, but apparently it's just not enough for the city of Chengdu in China. Not satisfied with the meager light the Moon reflects back down to Earth at night, scientists in the region plan to launch a satellite that will actually reflect sunlight back down to Earth and turn night into day... sort of.
The satellite is effectively a giant mirror that will redirect sunlight back down on Chengdu even after the Sun sets. The spacecraft will be roughly eight times brighter than the Moon, according to the Chengdu Aerospace Science and Technology Microelectronics System Research Institute, and should provide enough light that it will actually make street lights totally irrelevant for at least part of the city.
If this all sounds kind of bizarre that's because it is. It really, really is. The group planning the satellite says the mirror will produce light over an area of between 5 and 50 miles. That's, well, not a very specific, and it's unclear from current reports just how long the satellite will last.
There's also been some very real concern that the mirror's never-ending glow could seriously impact natural cycles of animals. Scientists have long been critical of human light pollution and its ability to potentially throw off the day/night rhythm of animals, and the same could be true of this fake moon plan. Some experts who support the plan suggest that it'll produce little more than a "twilight glow" that shouldn't change how animals behave, but nobody will know for certain until the satellite is up and running.
The institute working on the satellite plans to have the fake moon deployed by 2020. There seems to be some conflicting information over just how bright the light will be — something bright enough to make street lights obsolete sure sounds like it's brighter than a "glow" — so it'll be interesting to see just how well the mirror works... or doesn't.
Using nothing more than a simple vial of saliva, millions of people have created DNA profiles on genealogy websites. This problem of access is one that Bonnie Berger, a professor of mathematics at the Massachusetts Institute of Technology, and her colleagues think they can solve, with a new cryptographic system to protect the information. "We're currently at a stalemate in sharing all this genomic data," Berger told AFP.
