Expectant Moms: Coffee Won't Harm Kids' IQ

Pregnant women, perk up! It's okay to indulge in your morning cup of coffee without worrying about it affecting your child's IQ, a new study finds. In the study, researchers found that children born to women who consumed caffeine while pregnant did not have lower IQs or more behavior problems than those born to women who didn't indulge in coffee. "Taken as a whole, we consider our results to be reassuring for pregnant women who consume moderate amounts of caffeine, or the equivalent to one or two cups of coffee per day," Sarah Keim, an assistant professor of pediatrics and epidemiology at The Ohio State University College of Medicine and co-author of the study, said in a statement.

Speaking More Than One Language Eases Stroke Recovery

There are ways to reduce your risk of having a stroke — for example, you can exercise more and not smoke. In a new study, bilingual stroke patients were twice as likely as those who spoke one language to have normal cognitive functions after a stroke, according to findings reported today (Nov. 19) in the journal Stroke. The reason for the difference appears to be a feature of the brain called "cognitive reserve," in which a brain that has built a rich network of neural connections — highways that can can still carry the busy traffic of thoughts even if a few bridges are destroyed.

The Science of Sugar: Is Corn Syrup the Same?

Scientists are still debating whether there is a real difference between the effects on a person's health of high-fructose corn syrup and those of sugar, even as the issue features in an ongoing lawsuit. The suits stem from an earlier lawsuit that sugar refiners brought in 2011 against the corn trade group, claiming that the group's description of high-fructose corn syrup (HFCS) as "corn sugar" and "natural" in an ad campaign was false. In 2012, the U.S. Food and Drug Administration ruled that corn syrup could not be called sugar.

Attention Disorder Drugs May Harm Kids' Sleep

Some children with attention deficit hyperactivity disorder (ADHD) who take stimulant medications to treat their symptoms may develop sleep problems, according to a new analysis of previous research. Researchers analyzed nine previous studies involving a total of 246 children and teens that examined the relationship between ADHD medications and sleep.

These Ancient Monster Galaxies Have Scientists Perplexed

New research has revealed 574 massive, ancient galaxies lurking in the night sky, and their existence so close to the time of the Big Bang calls into question scientists' best understanding of how large galaxies form. A new video released Wednesday (Nov. 18) from the European Southern Observatory (ESO) reveals the ancient galaxies' locations. "We are talking about massive galaxies, twice as massive as the Milky Way today," said Karina Caputi, an astronomer at University of Groningen in the Netherlands and lead author on the new work.

Why NASA Europa Probe Will Study Jupiter Moon's Dust

BOULDER, Colo. — "Think about it as pieces of a puzzle," Zoltan Sternovsky said. NASA plans to launch a robotic Europa flyby mission in the early 2020s to address this question, and Sternovsky is part of a team developing one of the spacecraft's nine instruments — the Surface Dust Mass Analyzer (SUDA), which will determine the composition of materials ejected from the surface of the frigid moon. "Each instrument on the Europa mission is going to assess one piece of this puzzle," Sternovsky said here Nov. 4 at the university's Laboratory for Atmospheric and Space Physics, following a presentation by SUDA principal investigator Sascha Kempf, who's also based at UC Boulder.

Cyborg Roses Wired with Self-Growing Circuits

Scientists have created a kind of cyborg flower: living roses with tiny electronic circuits threaded through their vascular systems. The miniscule electronic polymers are inserted into the plant, then almost magically self-assemble thanks to the rose's internal structure. "In a sense, the plant is helping to organize the electronic devices," said study co-author Magnus Berggren, an organic electronics researcher at Linköping University in Sweden.

Antarctica Is Gaining Ice, So Why Is the Earth Still Warming?

NASA recently released a study suggesting that the Antarctic Ice Sheet is gaining more ice than it is losing — a finding that, at first blush, seems to contradict the idea of global warming. So, how can Antarctica be gaining ice mass in a warming world where ice sheets are collapsing and the melting is predicted to increase sea levels across the globe?

Green car technologies collide in Los Angeles

By Alexandria Sage LOS ANGELES (Reuters) - Asian automakers are opening up a new front in the contest to define the future of cars in California, fielding a flock of cars powered by hydrogen in a bid to woo green car buyers from Tesla Motors Inc, the battery electric vehicle leader. Toyota, Honda and Hyundai used the opening days of the Los Angeles auto show, which draws thousands of car enthusiasts in one of the world's richest vehicle markets, to tout new fuel-cell cars. Automakers plan to offer these cars in California, although the rollout will be limited.

Songbirds Woo Mates with Invisible Tap Dance

With the help of high-speed video, researchers from Hokkaido University in Japan and the Max Planck Institute for Ornithology in Germany have discovered that blue-capped cordon-bleu songbirds (Uraeginthus cyanocephalus) perform foot-stomping step dances during their courtship displays that are too quick to view with the naked eye. Because the birds only start tapping when their potential mates are on the same perch, the study authors think the dancers might punctuate the display with pleasing sounds or vibrations.

Scientists on quest for friction-free oil

By Matthew Stock Scientists from BP are applying molecular science in their laboratories to make the perfect oil blend to reduce engine friction and increase efficiency. According to the company, friction caused by various metal-to-metal contact points is a major problem for car engines; costing the UK economy an estimated 24 billion pounds (36.2 billion USD) each year through lost efficiency and damage through wear and tear. The only barrier between the high-force contacts of engine surfaces is a thin layer of lubricant, but they are coming under increasing pressure from modern engines. ...

'Letterlocked' Trove: X-Rays to Peer into Sealed 17th-Century Notes

For years, Jana Dambrogio, a conservator at MIT, has been studying the elaborate ways people used to fold and seal their letters to keep busybodies and spies from reading their secrets. The way a paleontologist analyzes fossils to reconstruct extinct creatures, Dambrogio looks at the blobs of wax and the folding patterns on flat, already-opened letters in manuscript collections so that she can reverse-engineer "letterlocking" techniques. "He asked me, 'What would you do if I told you there was a trunk with 600 unopened letters?'"Dambrogio said.
