The effectiveness of the Komodo dragon bite is a combination of highly specialized serrated teeth and venom, a new study shows. The authors also dismiss the widely accepted theory that prey die from septicemia caused by toxic bacteria living in the dragon’s mouth.
Scientists have developed new insights into how one kind of memory works. The study shows that laboratory rats have “episodic-like memory” and could open novel ways to study life-robbing loss of memory in humans.

Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7 percent accurate and sensitive enough to discern the arrival of a single atom in less than one-millionth of a second, about 20 times faster than the best previous methods.
Cystic fibrosis patients may benefit from a new therapy that increases airway hydration, preventing the buildup of mucous, which is a key factor in the disease.
The answer to the looming fuel crisis in the 21st century may be found by thinking small, microscopic in fact. Microscopic organisms from bacteria and cyanobacteria, to fungi and microalgae, are biological factories that are proving to be efficient sources of inexpensive, environmentally friendly biofuels that can serve as alternatives to oil, according to new [...]

Charles Darwin described the sudden origin of flowering plants about 130 million years ago as an abominable mystery, one that scientists have yet to solve. But a new study is helping shed light on the mystery with information about what the first flowers looked like and how they evolved from nonflowering plants.

A new drug-free treatment for asthma has been shown to be effective in an international study of patients with severe, uncontrolled asthma. Conducted at 30 sites around the world, the trial tested a procedure designed to reduce the ability of the lung’s airways to contract and interfere with breathing.

A new study using advanced cardiac imaging technology indicates that cardiac abnormalities experienced by some marathon runners following competition are temporary, and do not result in damage to the heart muscle. The study marked the first use of cardiac magnetic resonance imaging, or CMR, in a post-marathon setting.
