Ford to take slow road on electric trucks: CEO
Tue,17 Apr 2012 08:32 PM PDT
Reuters - LOS ANGELES (Reuters) - Ford Motor Co will be slower to build electric-powered pickups and other larger vehicles because the batteries to power them are still extremely costly, Ford CEO Alan Mulally said on Tuesday. The second-largest U.S. automaker is now electrifying the platforms used to build compact cars and mid-size sedans, a move that allows Ford to curb costs by building electric, hybrid and gas-powered versions of the same car on a single assembly line. ...

Is humanity quietly abandoning a future in space?
Tue,17 Apr 2012 10:30 AM PDT
Reuters -  WASHINGTON, April 17 - As astronaut Leroy Chiao watches the space shuttles he crewed make their final journeys to become museum pieces, he worries humankind is unthinkingly ditching space exploration and a future beyond Earth. After flying its last mission into space last year, the shuttle Discovery arrived Tuesday at Dulles International Airport outside Washington, D.C., atop a NASA 747 to enter the National Air and Space Museum at its giant Udvar-Hazy facility in suburban Virginia. ...

Space shuttle Discovery makes final flight to museum
Tue,17 Apr 2012 09:12 AM PDT
Reuters -  CAPE CANAVERAL, Florida (Reuters) - The space shuttle Discovery made its final voyage on Tuesday: a piggyback jet ride to the Smithsonian National Air and Space Museum annex in Virginia. The United States retired its space shuttles last year after finishing construction of the $100 billion International Space Station, a project of 15 countries, to begin work on a new generation of spaceships that can carry astronauts to destinations beyond the station's 240-mile-high (384-km-high) orbit. ...

Dinosaur eggs said found in Russia's Chechnya
Tue,17 Apr 2012 08:37 AM PDT
Reuters -  GROZNY, Russia (Reuters) - Geologists in Russia's volatile Chechnya region have discovered what they believe to be fossilized dinosaur eggs laid by one of the huge extinct reptiles that roamed the Earth more than 60 million years ago. "We've found about 40 eggs so far, the exact number has not been established," said Said-Emin Dzhabrailov, a geologist at the Chechen State University. "There could be many more laying under the ground. ...

Turmeric extract may protect heart after surgery
Fri,13 Apr 2012 03:19 PM PDT
Reuters - NEW YORK (Reuters Health) - A new study from Thailand suggests that extracts from turmeric spice, known for their antioxidant and anti-inflammatory properties, may help ward off heart attacks in people who've had recent bypass surgery. During bypass surgery the heart muscle can be damaged from prolonged lack of blood flow, increasing patients' risk of heart attack. The new findings suggest that curcumins -- the yellow pigment in turmeric -- may be able to ease those risks when added to traditional drug treatment. ... Full Story | Top |
Scientist beams up a real "Star Trek" tricorder
Fri,13 Apr 2012 02:12 PM PDT
Reuters -  LOS ANGELES (Reuters) - Starships, warp speed, transporters, phasers. Think "Star Trek" technology is only the stuff of fiction? Think again. Dr. Peter Jansen, a PhD graduate of the Cognitive Science Laboratory at McMaster University in Hamilton, Ontario, Canada, has developed a scientific measurement device based on the tricorders used by Captain Kirk, Spock, Dr. McCoy and other space adventurers on the classic TV series that has spawned numerous spin-offs in more than 45 years. ...

Space pictures pick up lots more penguins
Fri,13 Apr 2012 02:08 PM PDT
Reuters -  LONDON (Reuters) - Scientists counting emperor penguins from space have found twice as many of the birds in Antarctica as expected. The discovery is reassuring for a species seen as under threat from global warming and will provide researchers with a benchmark for monitoring the giants of the penguin world in years to come. Using high-resolution satellite images to study each of 44 colonies around the coastline of Antarctica, experts said on Friday they put the total emperor penguin population at 595,000, or roughly double previous estimates of 270,000 to 350,000. ...

Scientists examine a hot epoch to forecast climate future
Fri,13 Apr 2012 11:31 AM PDT
Reuters -  WASHINGTON (Reuters) - To figure out what is likely to happen to Earth's climate this century, scientists are looking 3 million years into the past. They have concluded that the most revealing slice of time is the Pliocene Epoch, a warm, wet period between 3.15 million and 2.85 million years ago, when the world probably looked and felt much as it does now. Global temperatures and the amount of heat-trapping carbon dioxide in the atmosphere were similar to today's climate, according to the U.S. Geological Survey. ...

Tennessee teacher law could boost creationism, climate denial
Fri,13 Apr 2012 09:53 AM PDT
Reuters -  (Reuters) - A new Tennessee law protects teachers who explore the "scientific strengths and scientific weaknesses" of evolution and climate change, a move science education advocates say could make it easier for creationism and global warming denial to enter U.S. classrooms. The measure, which became law Tuesday, made Tennessee the second state, after Louisiana, to enable teachers to more easily teach alternative theories to the widely accepted scientific concepts of evolution and human-caused climate change. At least five other states considered similar legislation this year. ...

Satellite mapping pinpoints penguin population
Thu,12 Apr 2012 11:11 PM PDT
Reuters -  SYDNEY (Reuters) - Counting emperor penguins in their icy Antarctic habitat was not easy until researchers used new technology to map the birds from space, and they received a pleasant penguin surprise for their efforts. Using satellite mapping with resolution high enough to distinguish ice shadows from penguin poo, an international team has carried out what they say is an unprecedented penguin census from the heavens over the past three years. The good news was that the team found the Antarctic emperor penguin population numbered about 595,000, nearly double previous estimates. ...

This is Dan. Dan is a Baboon. Read, Dan, Read
Thu,12 Apr 2012 12:16 PM PDT
Reuters -  NEW YORK (Reuters) - No one is exactly using the words "reading" and "baboons" in the same sentence, but a study published Thursday comes close. Researchers report in the journal Science that they trained six Guinea baboons (Papio papio) to distinguish real, four-letter English words such as "done" and "vast" from non-words such as "dran" and "lons." After six weeks, the baboons learned to pick out dozens of words — as many as 308 in the case of the clever Dan, and 81 for Violette — from a sea of 7,832 non-words. ...

U.S. new car gas mileage up 20 percent since 2007: study
Tue,10 Apr 2012 08:06 AM PDT
Reuters -  (Reuters) - New cars and trucks sold in the United States are getting an average of 24 miles per gallon of gasoline, the highest ever, researchers at the University of Michigan said on Tuesday. The average fuel economy rating as shown by window stickers on new vehicles bought in March - including pickup trucks, SUVs, minivans and passenger cars - was 24.1 mpg, the researchers found. That was up 20 percent from the average of 20 mpg in October 2007, they said. The university's Transportation Research Institute began monthly updates on fuel economy four-and-a-half years ago. ...

CERN revs up hopes for smashing year for physics
Thu,5 Apr 2012 12:06 PM PDT
Reuters - GENEVA (Reuters) - Scientists came closer than ever to witnessing "Big Bang"-style conditions on Thursday after revving up the Large Hadron Collider at the CERN research centre to smash sub-atomic particles together faster and harder than ever before. Physicists in the control rooms punched the air as multi-colored arcs flashed across their screens, debris thrown up by the collisions of some of the millions of protons flung around the vast underground circuit at close to the speed of light. "This is a great start to the 2012 run. ... Full Story | Top |
