A study has revealed one reason why people who suffer from chronic inflammatory diseases such as colitis have a higher risk of mutations that cause cancer. The researchers also found that exposure to DNA-damaging chemicals after a bout of inflammation boosts these mutations even more, further increasing cancer risk.
Researchers have found further evidence to suggest that eyewitnesses to crimes remember more accurate details when they close their eyes. The team also discovered that building a rapport with witnesses also helped them to remember more.
Sea turtles migrate across thousands of miles of ocean before returning to nest on the same stretch of coastline where they hatched, but how they do this has mystified scientists for more than 50 years. Now, researchers have learned that adult sea turtles find their way home by seeking out unique magnetic signatures along the coast.
“Here’s some of the stories trending This Week at NASA!” Dragon arrives at ISS
The January issue of Laboratory Equipment features a cover story on the advancement of robotics in the lab, in society and in the world. This issue also features a list of good mobile apps for lab professionals. Other articles cover confocal microscopy, the future of UV/Vis, strategies for sustainable lab design and designing a lab around collaborative science.
Young children with disruptive behaviors have fewer opportunities to learn in school than their focused peers. But, a study found that kindergartners and first graders with high maintenance temperaments showed less disruptive behavior and more active engagement and on-task behavior in the classroom, thanks to a program that helps teachers, parents and students recognize and adapt to individual differences.
The Smithsonian Associates education program is opening its 50th year with new initiatives focused on the news and art history and speakers including Supreme Court justices and actor Martin Sheen. This week the program is launching a new series called Smithsonian Newsflash to look behind the headlines to provide context on breaking news.
Education Secretary Arne Duncan said this week that testing U.S. schoolchildren annually in math and reading is critical for measuring their educational progress, setting the stage for what is likely to be a contentious Capitol Hill debate on the federal role in education. His speech was the Obama administration's latest effort to make its case for federally mandated testing.
From 15th century, one-page hornbooks to “teaching machines” such as PLATO, to massive open online courses, or MOOCs, visionary educators long have trumpeted new technology to revolutionize classroom learning. So far, none of these heralded innovations have received an A. A research professor has analyzed why the ideas rarely became successful but remains hopeful that the pace of change today will yield better results in the near future.
In 1961, Stanley Milgram undertook a series of now infamous experiments on obedience and reprehensible behavior. About two-thirds of nearly 800 study subjects were willing to administer increasingly powerful electric shocks to an unseen stranger despite cries of agony and pleas. A researcher reexamining the results says there may be a way to prevent real-world occurrences of authority overriding ethical judgment.
A pair of Case Western Reserve Univ. engineering students are field testing their foot-powered cellphone charger in rural villages of the Kingdom of Lesotho, a small country surrounded entirely by South Africa, this week. In the country, up to 60 percent have cellphones but only a quarter have access to electricity.
Acute care nurse practitioner students, specializing in flight nursing at Case Western Reserve Univ. (CWRU), will soon be training in the nation’s first state-of-the-art simulator built in an actual helicopter. The simulator creates the sense of treating critically injured patients from takeoff to landing.
This idea is not just in its infancy, it's literally in diapers. A new trick for revealing tiny details under a microscope draws on a technology that helps make disposable diapers so absorbent.
A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood. Researchers have described a surprisingly dynamic system that offers several clues for improving bone-marrow transplants in patients with cancer, severe immune deficiencies and blood disorders, and for helping those transplants “take.”
By shedding light on the action of two naturally occurring hormones, scientists may have discovered a way to assist in the shedding of excess fat. The researchers have unraveled a molecular mechanism that depends on the combined action of two hormones— leptin, an appetite suppressant generated in fat cells, and insulin, produced in the pancreas in response to rising levels of glucose in the blood.
