Scientists studying the distribution of four commercial and recreational fish stocks in Northeast US waters have found that climate change can have major impacts on the distribution of fish, but the effects of fishing can be just as important and occur on a more immediate time scale. The four species studied -- black sea bass, scup, summer flounder, and southern New England/Mid-Atlantic Bight winter flounder -- have varied in abundance and have experienced heavy fishing pressure at times over the past 40 years.
Researchers have found that a Rocky Mountain mustard plant alters its physical appearance and flowering time in response to different environmental conditions, suggesting some species can quickly shape-shift to cope with climate change without having to migrate or evolve.
Online giants including Amazon and LinkedIn could be doing far more to raise awareness of the need for better password practices among their users, a study by Plymouth University has found.
In 2014, researchers at the California Academy of Sciences added 221 new plant and animal species to our family tree. The new species include 110 ants, 16 beetles, three spiders, 28 fishes, 24 sea slugs, two marine worms, 9 barnacles, two octocorals, 25 plants, one waterbear, and one tiny mammal.
High-risk patients with certain acute heart conditions are more likely to survive than other similar patients if they are admitted to the hospital during national cardiology meetings, when many cardiologists are away from their regular practices.
New laws regulating concussion treatment, bolstered by heightened public awareness, have resulted in a large increase in the treatment of concussion-related injuries for school-age athletes.
Researchers criticize reforms advocated by the IMF for chronically under-funded and insufficiently staffed health systems in Guinea, Liberia and Sierra Leone. They say these policies contributed to 'lack of preparedness' of West African health systems to cope with disease and emergencies such as Ebola.
Not all species may suffer from climate change. A new analysis shows that Dolly Varden, a species of char common in southeast Alaska, adjust their migrations so they can keep feasting on a key food source -- salmon eggs -- even as shifts in climate altered the timing of salmon spawning.
In new findings published online in the journal Annals of Surgery on Dec. 19, 2014, researchers determined the hospital costs and risk of death for emergency surgery and compared it to the same operation when performed in a planned, elective manner for three common surgical procedures: abdominal aortic aneurysm repair, coronary artery bypass graft and colon resection.
Researchers at Montana State University and Brandenburg University of Applied Sciences in Germany have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus. The model, and stunning pictures of the springs, appear today in the journal Applied Optics.
