It seems counter-intuitive that in order to survive best as a species, not everything can live forever, but some cells in our bodies are fated to die, and a Mission Impossible-style auto-destruct program insures they do.

This elaborate cell death program, known as apoptosis, got a little more insight with a study on the evolution of caspase-8, a key cell death initiator molecule that was first identified in humans. By performing the most extensive evolutionary analysis of the Casp8 protein to date,

A recent model says it provides the first characterization of the progenitor for a hydrogen-deficient supernova. Their simulation predicts that a bright hot star, which is the binary companion to an exploding object, remains after the explosion so they secured observation time with the Hubble Space Telescope (HST) to search for such a remaining star.  

Unless you are trapped at a Larry Summers protest at Harvard in 2006, you know that male and female brains are not equal in all ways.

Another study affirms that, finding a difference when it comes to the biological response to a high-fat diet. Cedars-Sinai Diabetes and Obesity Research Institute scientist Deborah Clegg, PhD, and colleagues found that the brains of male laboratory mice exposed to the same high-fat diet as their female counterparts developed brain inflammation and heart disease that were not seen in the females.

Reading glasses have served us for centuries. Why fix a good thing? Because science and technology can. 

Presbyopia, blurriness in near vision experienced by many people over the age of 40, could one day be relegated to olden days if a thin ring inserted into the eye gains popularity.

A new study has found that people who play action video games such as the "Call of Duty" or "Assassin's Creed" seem to learn a new sensorimotor skill faster than non-gamers do. Sorry, Bungie, "Destiny" was not out when they did the study and auto-rifles would mess up the results anyway.

A new sensorimotor skill, such as learning to ride a bike or typing, often requires a new pattern of coordination between vision and motor movement. With such skills, an individual generally moves from novice performance, characterized by a low degree of coordination, to expert performance, marked by a high degree of coordination. As a result of successful sensorimotor learning, one comes to perform these tasks efficiently and perhaps even without consciously thinking about them.

When most people think of first responders, they think of paramedics or combat medics or other medically-trained personnel doing CPR and other life-saving procedures in stressful situations.

They do not think of acupuncture.
 
A review article in Medical Acupuncture - since it is a review, it is collating other articles about acupuncture, rather than science or medicine - argues that first responders should be trained in integrative medicine approaches such as acupuncture, hypnosis and biofeedback to provide adjunctive treatment to help relieve patients' pain and stress. Maybe they could teach some yoga and the benefits of organic food during the next earthquake as well.
