The sun ejected two huge solar flares Tuesday, and NASA says that we here on Earth will likely be affected somewhat by the magnetic fields and ionized gas that are now shooting toward the planet. But the phenomena might also bring aurora light shows to residents of the northern United States
The United States and five other nations are embarking on a new program to limit pollutants connected to global warming. But they’re not targeting carbon dioxide with this effort — instead, they’re looking at methane gas, and soot.
There may be some good news in regard to amputation rates in patients with diabetes in the United States.
A recent study in Diabetes Care found that nontraumatic lower extremity amputation rates have decreased in patients with diabetes over age 40.1 Lin and colleagues found the amputation discharge rate per 1,000 people with diabetes was 3.9 in 2008 — down from 11.2 in 1996.
Easy-to-chew foods like rice and corn may have influenced the evolution of the human jawbone. New research says it may also help account for the fact that children in the United States often need to have braces because their mouths can’t accommodate their teeth.
I was thinking recently about how we react to shared impending calamity (or challenge). The Allies worked together to battle a shared enemy in World War II. The Manhattan Project was an example of this (for better or worse). We worked together within the United States to reach the moon (as a challenge from Sputnik and our then adversaries in the U.S.S.R.). I am sure that if we faced a shared disaster such as a killer asteroid, we would all probably team up to nudge that rock into someone else’s orbit.
The 6-ton NASA satellite clung to space Friday, apparently flipping position in its ever-lower orbit and stalling its death plunge. Canada, Africa and Australia are in the potential crosshairs, although most of the satellite should burn up during re-entry. The United States wasn’t entirely out of the woods either.
Can the total ankle replacement (TAR) provide a viable alternative to ankle arthrodesis? In addition to reviewing the FDA approved TARs in the United States, advances in device design and the current literature, these authors emphasize proper patient selection, sound pre-op planning and other insights from their experience in performing total ankle arthroplasty procedures.
With plans for the Yucca Mountain nuclear waste repository scrapped, the United States has no central facility to permanently store used-up nuclear fuel from reactors. In the meantime, utilities around the country are stuck with some 65,000 tons of nuclear waste.
Google Plus isn’t Google’s first foray into social networking–Orkut and Buzz already exist, but neither caught on in the United States. Can Google Plus do better? Danny Sullivan, editor-in-chief of Search Engine Land, discusses how the new social network stacks up to Facebook and Twitter.
Given the changing population demographics in the United States, it is more important than ever to be able to recognize and treat dermatologic conditions that are more prevalent among patients with skin of color. Accordingly, this author discusses the diagnosis and treatment of skin conditions including vitiligo, melanonychia and keloids.
The devastating earthquake in Haiti, which occurred on January 12, has gotten the attention of the world-and podiatrists from across the United States have quickly jumped at the chance to provide life-saving care to those injured.
