Experts: CO2 record illustrates ‘scary’ trend May 11, 2013 12:00 AM
Within a decade the world will never see days — even in the cleanest of places on days in the fall when greenhouse gases are at their lowest — when the carbon measurement falls below 400 ppm, said James Butler, director of global monitoring at the National Oceanic and Atmospheric Administration's Earth Science Research Lab in Boulder, Colo."The 400 is a reminder that our emissions are not only continuing, but they're accelerating; that's a scary thing," Butler said Saturday. "We're stuck. We're going to keep going up."
NASA mulls spacewalk to fix station leak May 10, 2013 12:00 AM
There may be some residual ammonia left which will help the spacewalkers find the leak, which is generating visible white flakes. If they wait longer, it will be harder to find the leak if there is no more ammonia left to come out in white flakes, spokesperson Kelly Humphries said.
Greenhouse gas milestone; CO2 levels set record May 10, 2013 12:00 AM
Carbon dioxide was measured at 400 parts per million at the oldest monitoring station, in Hawaii, which sets the global benchmark. The last time the worldwide carbon level was probably that high was about 2 million years ago, said Pieter Tans of the National Oceanic and Atmospheric Administration.
Experimental Air Force aircraft goes hypersonic May 3, 2013 12:00 AM
The Air Force said in a statement Friday the X-51A WaveRider flew for more than three minutes under power from its exotic scramjet engine and hit a speed of Mach 5.1
New maps show where the Asian carp are Apr 26, 2013 12:00 AM
The U.S. Army Corps of Engineers, Illinois Department of Natural Resources and U.S. Geological Survey have released current data on the presence of bighead carp and silver carp at all life stages, as well as black carp and grass carp occurrences, in the Mississippi River, Ohio River and Great Lakes.
Newfound hormone holds hope for diabetes treatment Apr 25, 2013 12:00 AM
Researchers identified a hormone they dubbed betatrophin in mice. When they made the liver in mice secrete more of it by inserting extra copies of the gene, the size of the beta cell population tripled in comparison to untreated mice. Tests indicated the new cells worked normally.
Liquid nitrogen, explosions and Newton’s Laws at Fermilab show Apr 14, 2013 12:00 AM
About 600 people packed Fermilab's Wonders of Science show — which has been going strong for more than a quarter-century — to see an hour's worth of experiments focused on acceleration. Chemistry and physics teachers Lee Marek, Karl Craddock and Bill Grosser ran the show, wowing kids and adults alike with fire, explosions and tricks. This year's theme focused on how to get particles to speed up or slow down and what happens when they do.
Libertyville High’s Mark Buesing working with NASA in GreenlandApr 13, 2013 12:00 AM
Veteran Libertyville High School science teacher Mark Buesing didn't go to Florida, Mexico or anywhere remotely tropical for spring break. Instead, Buesing packed some cold-weather gear and headed to glacier-filled Greenland, where he's part of a NASA mission to study ice in both of our planet's polar regions.

Big Bang gets clearer as universe ages 80M years Mar 24, 2013 12:00 AM
New results from looking at the split-second after the Big Bang indicate the universe is 80 million years older than previously thought and provide ancient evidence supporting core concepts about the cosmos — how it began, what it's made of and where it's going. The findings released bolster a key theory called inflation, which says the universe burst from subatomic size to its now-observable expanse in a fraction of a second.
Letter from DNA discoverer Crick could fetch $1 million Mar 23, 2013 12:00 AM
Sixty years ago scientist Francis Crick wrote a letter to his 12-year-old son saying he and a colleague had discovered something "very beautiful" — the structure of DNA.Now, the note and its hand-drawn diagrams are being auctioned off in New York. Christie's estimates the letter could fetch $1 million or more at the April 10 sale.
At Argonne, Obama warns federal cuts will hurt research Mar 15, 2013 12:00 AM
The impact of the federal sequester heavily influenced President Barack Obama's speech to scientists at Argonne National Laboratory Friday afternoon, as he painted a bleak picture of American research being outpaced if funding dries up. "In a time where every month you've got to replace your smartphone, imagine what that means when China, Germany and Japan are pumping up basic research and we're just sitting there doing nothing," he said.
Obama wants research to wean vehicles off oil Mar 15, 2013 12:00 AM
President Barack Obama is pushing Congress to authorize more federally funded research into clean energy technologies that can wean automobiles off oil. Obama proposed the idea of an energy security trust last month in his State of the Union address, but he was putting a price tag on the idea during a trip Friday to the Argonne National Laboratory outside Chicago — $2 billion over 10 years.
Study: Radiation for breast cancer can harm hearts Mar 13, 2013 12:00 AM
Women treated with radiation for breast cancer are more likely to develop heart problems later, even with the lower doses used today, troubling new research suggests. The risk comes from any amount of radiation, starts five years after treatment and lasts for decades, doctors found.
Tough winter forces owls south in hunt for food Mar 13, 2013 12:00 AM
It's been a tough winter for owls in parts of North America, and the evidence is turning up on roadsides, at bird feeders and at a wildlife rehab center in Minnesota.
Buffalo Creek needs more cleanup, agency saysMar 9, 2013 12:00 AM
The waters of Buffalo Creek are not very healthy, a representative of the Buffalo Creek Clean Water Partnership said this week. Jeff Weiss, the partnership's founder, said their study has shown the lake water contains phosphorous, suspended solids and dissolved oxygen; and in the creeks, fecal coliform chloride and dissolved oxygen levels that exceed EPA allowances.
