A glasswing butterfly feeding at flowers in Costa Rica. The remarkable transparency of these butterflies allows them to be “invisible,” and the antiglare coating of their wings helps to prevent them from being given away by any glare of sunlight off their wings.

In a paper published in Science, biologists at Baylor College of Medicine, the Netherlands Cancer Institute and Rice University studying the tree of life unveil a new classification system for cell nuclei and the discovery of a method for transmuting one type of cell nucleus into another. This illustration shows […]

Illustration of fat cells. Nuclear power offers an efficient, reliable way to provide energy to large populations — as long as all goes well. Accidents involving nuclear reactors such as those that took place in 1986 at Chernobyl and at Fukushima Daiichi after the March 2011 tsunami raise major concerns […]

ANIMATION Proof-of-concept study represents first successful attempt to reverse the aging clock in animals through epigenetic reprogramming. Scientists turned on embryonic genes to reprogram cells of mouse retinas. Approach reversed glaucoma-induced eye damage in animals. Approach also restored age-related vision loss in elderly mice. Work spells promise for using same […]

There are notable impacts on the biology of living things in the harsh environment of space. A team of scientists has now identified a possible […]

ANIMATION For the first time, researchers describe how Rho protein really stops gene expression. New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now — precisely how the copying of genetic material that, once started, is properly turned off. […]

Turning off a newly identified enzyme could reverse a natural aging process in cells. Research findings by a KAIST team provide insight into the complex mechanism of cellular senescence and present a potential therapeutic strategy for reducing age-related diseases associated with the accumulation of senescent cells. Simulations that model molecular interactions have […]
