Oliver Sacks, neurologist and writer, died on Sunday at age 82. Sacks cataloged both disease, and the diversity of human response to it, over decades. He again entered the public eye writing about his own encounter with terminal cancer – conveying a sense of gratitude for his long life in a much-heralded New York Times piece.
An international group of researchers have found that food craving activates different brain networks between obese and normal weight patients. This indicates that the tendency to want food may be “hard-wired” into the brain of overweight patients, becoming a functional brain biomarker.
In a study, researchers took 24 students with light to moderate cocaine use, and gave them either 300 mg of oral cocaine, or a placebo. After one to two hours, each participant was then subject to a series of biochemical tests, as well as the facial emotion recognition test to measure response to a series of basic emotions. The subjects who took cocaine found it more difficult to recognize negative emotions.
The editors of Laboratory Equipment want you to start your week with a smile on your face. So, here’s a science joke you might like. Q: Why did hydrogen marry carbon?
Oysters serve as a major reservoir for noroviruses– the raw ones should be avoided, according to a new study. But seafood industry experts say the shellfish danger is overstated.
Diets rich in fish oil versus diets rich in lard produce very different bacteria in the guts of mice, reports a study. The researchers transferred these microbes into other mice to see how they affected health. The results suggest that gut bacteria share some of the responsibility for the beneficial effects of fish oil and the harmful effects of lard.
A study found that two popular medical dramas show cardiopulmonary resuscitation (CPR) successfully saving a “patient’s” life in nearly 70 percent of the scenes in which it was used. Half of the fictional patients who received CPR made enough of a recovery to eventually leave the hospital. That’s almost double the actual immediate survival rate of less than 37 percent and four times the real long-term survival rate of roughly 13 percent.
Among the many things that science is, it is a system of categorization. The human fossil record is rather poorly categorized, contends a professor, leading to a narrow view of what he believes to be a more complex and expansive evolutionary history than most anthropologists recognize.
Researchers have developed a procedure to mimic in laboratory experiments a form of brain trauma commonly seen in combat veterans, and findings suggest a new diagnostic tool for early detection and a potential treatment.
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. Now, atmospheric chemists have determined just how effective rain is in cleaning the atmosphere. Given the altitude of a cloud, the size of its droplets and the diameter and concentration of aerosols, the team can predict the likelihood that a raindrop will sweep a particle out of the atmosphere.

Buzz Aldrin has gone where no man had gone before, he’s gotten a doctorate, he’s a universally loved American icon and a star of Twitter and TV. Now, at 85, he’s starting a new adventure– in Florida.
A new method of manufacturing glass could lead to the production of “designer glasses” with applications in advanced photonics, while also facilitating industrial scale carbon capture and storage. An international team of researchers has reported how they have managed to use a relatively new family of sponge-like porous materials to develop new hybrid glasses.
A large group of researchers set out to repeat 100 experiments published by leading psychology journals to see how often they would get the same results. The answer: less than half the time. But, that doesn't mean all those unconfirmed studies were wrong.
In 2011, neuroscientists reported that, in blind adults, brain regions normally dedicated to vision processing instead participate in language tasks such as speech and comprehension. Now, in a study of blind children, the same lab has found that this transformation occurs very early in life, before the age of four.
