The nature of light puzzled some of humanity’s greatest thinkers for 2,000 years, behaving like a wave in certain conditions and as a particle in others. … […]
Researchers have recently identified a DNA region known as VNTR2-1 that appears to drive the activity of the telomerase gene, which has been shown to prevent aging in certain types of cells. Knowing how the telomerase gene is regulated and activated and why it is only active in certain cell types… […]
There are a few different methods to determine the age of a star, but none are perfect. … […]
An ancient shark bite victim died quickly, before his body was recovered and buried, a new study finds. … […]
Researchers have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition. … […]
Scientists have shown that cockatoos can learn from each other a unique skill — lifting garbage bin lids to gather food. The research confirms that cockatoos spread this novel behavior through social learning. … […]
As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight? … […]
Scientists have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age. … […]
Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date. … […]
Researchers have found a low-cost way to solve one half of the water-splitting equation to produce hydrogen as clean energy — using sunlight to efficiently split off oxygen molecules from water. The finding represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure. … […]
