There are hundreds of types of cancers. Almost all of them are classified by the organ in which they first appear. This system made it easy for surgeons to operate, but today, we know that cancers are largely caused by genetic disorders. Unfortunately, by the time most cancers are identified in an organ, it’s too late. ... Read more »

Dogs can hear sounds we can’t, and many other animals can see light beyond our human “visual spectrum,” such as ultraviolet light waves to find prey or avoid becoming prey. But until now, the near infrared spectrum was considered off limits to animals.
New research led by Dr. Sebastian Baldauf from the University of Bonn reports on the first known fish with infrared vision. The study appears in the October 21 online edition of NaturWissenschaften. The fish, called Pelvicachr........ Read more »

You wouldn’t think that the sex life of the horseshoe crab would be that complicated, but you’d be wrong. Like every red blooded guy out there, horseshoe crabs have to think long and hard about the best way to attract a mate (even though horseshoe crab blood is actually blue). While human males have many options to choose, from say writing a romantic poem, or buying a lovely bunch of flowers for their sweetheart, crabs are generally limited to two different options....

Stem cell research promises to revolutionize the available treatments for many neurological disorders such as Parkinson’s disease and Alzheimer’s.

Numerous studies have demonstrated that inhaling tobacco smoke increases the risk on various cancers, heart complications, stroke and other health problems. Now new research adds another hazard, but this time it’s a mental one: smoking may damage memory, learning and reasoning capacities – if you’re older than 50.
Researchers at King’s College, London, asked 8,800 people over the age of 50 to perform cognitive, verbal-fluency and attention tests. They were all tested a........ Read more »

Boredom is more than just a temporary feeling. It can cause significant stress and is associated with depression, anxiety, substance abuse and even compulsive gambling. Worse, boredom often leads to fatal accidents, even among highly trained and focused professionals like airline pilots or military personnel handling nuclear-powered equipment.

Although history has often revealed itself to be cyclical, this is one cirsumstance humanity should hope to never repeat. A new paper presented last week at the Geological Society of America uncovered why plants and animals did not quickly recover from the largest mass extinction in Earth’s history.
The era passed 250 million years ago, but the culprit was a familiar offender: global warming.
The environmental impact of rising temperatures stagnated species recovery for 5 million ye........ Read more »

I love that cute is good for us. All this talk of cute, a website and some observations at home got me thinking this week. I recently saw this image posted on Facebook and I don’t mind admitting that it tugged at my emotions.

Animal-model research examines molecular mechanisms for blood-pressure lowering effect of ancient Chinese therapy

The study findings were reported online last month in the biomedical jo........ Read more »
