Astronomers can look back in time by gathering light from distant stars that was sent billions of years ago. Another way to learn about the past is to study similar stars to our own, but at a much younger age.

New work  studying the young star TW Hydrae, located about 190 light-years from Earth in the southern constellation Hydra the Water Snake, suggests that our Sun was both active and "feisty" in its infancy, growing in fits and starts while burping out bursts of X-rays.

In one sense, I am happy that there is enough interest in the concept of “junk DNA” (and by extension, my area of research in genome size evolution) that the subject gets regular media attention.

Studies have shown that religious people are actually helped by faith in stressful situations.

Oxford University psychologists suggest atheists are also helped by belief during times of crisis; the explanatory and revealing power of science increases in the face of stress or anxiety, they have found.

The social psychologists argue that a 'belief in science' may help non-religious people deal with adversity by offering similar comfort and reassurance that religious people get from spirituality.

Karlsruhe's Institute of Technology, Freie Universität Berlin and the University of Geneva set out to determine whether and how far laser light and plasma can influence cloud formation.

The world’s oldest known fossil primate skeleton, unearthed from an ancient lake bed in central China’s Hubei Province, near the course of the modern Yangtze River, represents a previously unknown genus and species that has been named Archicebus achilles, according to the paper in Nature. 

The new fossil takes its name from the Greek arche (meaning beginning or first; the same root as archaeology) and the Greek kebos (meaning long-tailed monkey). The species name achilles (derived from the mythological Greek warrior Achilles) highlights the new fossil’s unusual ankle anatomy.

You're an animal, says Dominique Lestel, a French philosopher who opposes the separation of human and animal life.  

In a new paper, Lestel reminds sociology readers that we are animals and says animals profoundly influence our culture – perhaps more so than they had initially thought.

Western thought that the human species is highly developed and that sets the human species apart. Lestel instead advocates animality (our animal nature) and says humanization is an ongoing performative practice, rather than a historical threshold that was crossed long ago.

A Georgia State University researcher says the Clean Air Act signed by President Richard Nixon in 1970 led to climate change - in a good way. 

Jeremy Diem, an associate professor in the Department of Geosciences, analyzed summer rainfall data from nine weather stations in the Atlanta metropolitan area from 1948 to 2009, and discovered that precipitation increased in the late 1970s after drops in the 1950s and '60s.

Cause: Passage of the Clean Air Act of 1970, he says. Pollution had been higher in the earlier decades. Some studies have found a general correlation between air pollution and rainfall, with higher concentrations of particulates in the air suppressing rainfall, they conclude.

Fuel cells can be as efficient (or more) than internal combustion engines, silent, and at least one type produces zero greenhouse emissions at the tail pipe. Car and bus manufacturers as well as makers of residential and small-business-sized generators have been testing and developing different forms of fuel cells for more than a decade but the high cost and insufficiencies of platinum catalysts have been the Achilles heel. 

An inexpensive and easily produced catalyst that performs better than platinum in oxygen-reduction reactions could be a step toward eliminating what industry regards as the largest obstacle to large-scale commercialization of fuel cell technology. 

While the Orion Nebula is one of the closest stellar nurseries to Earth and that makes for great viewing in backyard telescopes, it is not the most prolific star-forming region in our galaxy. That distinction may go to the Cat's Paw Nebula, otherwise known as NGC 6334, formally known as  NGC 6334, which is experiencing a "baby boom."

The drug aflibercept, under the trade name Eylea, has been approved in Germany since November 2012 for the treatment of wet age-related macular degeneration (AMD). 

In an early benefit assessment pursuant to the Act on the Reform of the Market for Medicinal Products (AMNOG), the German Institute for Quality and Efficiency in Health Care (IQWiG) examined whether this new drug offers an added benefit over the current standard therapy. Such an added benefit cannot be derived from the dossier, since the manufacturer did not submit data for the comparison, says the advocacy group in Germany.
