president of Friends of the Earth, an environmental group that opposes nuclear power, argues that nuclear plants take too long to build and that the problems of waste and aging reactors haven’t been solved
This has been an incredible year of scientific achievement. Even the lay public is coming to the realization that profoundly extended health spans may be just around the corner. A concern expressed by our older members is whether they can remain alive long enough to benefit from the upcoming bi...
Each one has a nucleus, energy production equipment, etc. Bacteria are single-celled organisms that are much simpler. For example, they have no nucleus. They are perhaps 1/100th the size of a human cell and might measure 1 micrometer long. Bacteria are completely independent organisms able ...
Scientists have wondered about this question for a long time, and new research published this week in Nature revealed the process that viral proteins use to replicate—which could lead to better gene therapy delivery and other new therapeutics. In this chicken o...
All living things use the genetic code to "translate" DNA-based genetic information into proteins, which are the main working molecules in cells. Precisely how the complex process of translation arose in the earliest stages of life on Earth more than four billion years ago has long been mysteri...

we're still a long way off from the type of sensation seen in the artificial limbs in star wars. this hand only provides rough sensations, but they're still useful, because now a patient can feel when there's an object in their hand and if that object is slipping away. but what ...
“In the 20 years of permanent ISS habitation, no health conditions requiring medical evacuation have presented to date on orbit,” he said, adding that this has been helped by the careful selection of astronauts who are at the peak of health and who are monitored for at least two years be...
in fields like nuclear fusion and quantum computing, where the odds are long but the payoffs potentially huge. “Sam believed he was the best at everything he took on,” says Mark Jacobstein, a veteran tech investor and startup adviser who worked with Altman at Loopt. “I am pretty sure...
Bathe or shower daily to cleanse the skin around the anus. Decrease straining with bowel movements. Increase fiber in the diet with supplements such as Metamucil, Benefiber, or foods such as prunes. Avoid sitting on the toilet too long. Apply ice packs to the affected area to decrease pain...
