Astronomers have observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust.
A new study suggests that adult bone marrow stem cells can be used in the construction of artificial skin. The findings mark an advancement in wound healing and may be used to pioneer a method of organ reconstruction. The study is published in Artificial Organs.

Some researchers have blasted biofuels’ potential to increase greenhouse gas emissions, calling into question the environmental benefits of making fuel from plant material. But a new analysis says these dire predictions are based on a set of assumptions that may not be correct.

Doctors may be implanting too many artery-opening stents and could improve patient outcomes — and ultimately save lives — if they did more in-depth measurements of blood flow in the vessels to the heart, according to experts.

Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood.

Marine biologists have discovered three broad classes of camouflage body patterns. This study of cephalopod camouflage has implications for analyzing camouflage tactics throughout the animal kingdom.
A study of almost 1500 people has uncovered a genetic mutation that is almost guaranteed to lead to heart disease. The mutation is found worldwide, but appears to be restricted to people with an origin in the Indian subcontinent, where 4 percent of the population are carriers. The size and simplicity of the genetic effect [...]
Imagine a world of ‘human perfection’ where disabled people are a distant memory, edited out by medical enhancement and economic cost-benefit analysis: a world where thanks to generic selection and economic crises disabled people find themselves expendable. Is such a world desirable? Not necessarily so, says one researcher.

A new mathematical model of the physiological regulation of body weight suggests a potential mechanism underlying the difficulty of losing weight, one that includes aspects of two competing hypotheses of weight regulation.
