For 400 years people have tracked sunspots, the dark patches that appear for weeks at a time on the sun's surface. They have observed but been unable to explain why the number of spots peaks every 11 years. A...
The world is experiencing unprecedented economic growth in low- and middle-income countries. An increasing number of people in India, China, Latin America and Africa have become wealthier, and this is reflected in their consumption of meat and dairy...
Few things on earth strike fear into the hearts of men more profoundly than hair loss. But reversing baldness could someday be as easy as wearing a hat, thanks to a noninvasive, low-cost hair-growth-stimulating technology developed by engineers...
Researchers have for the first time restructured Denisovans' skeletal features, using DNA methylation (chemical changes), to understand how the long–lost human relative looked like, the Nature reported. A team of computational biologists at the Hebrew University of Jerusalem found...
Researchers have discovered an ancient asteroid collision sparked an ice age by blasting masses of dust into the atmosphere. 446 million years ago, the Earth experienced a period of global cooling. The poles started to freeze, and life flourished...
What determines global patterns of biodiversity has been a puzzle for scientists since the days of von Humboldt, Darwin, and Wallace. Yet, despite two centuries of research, this question remains unanswered. The global pattern of mountain biodiversity, and...
Inspired by octopuses, researchers have developed a structure that senses, computes and responds without any centralized processing -- creating a device that is not quite a robot and not quite a computer, but has characteristics of both. The...
While computers have become smaller and more powerful and supercomputers and parallel computing have become the standard, we are about to hit a wall in energy and miniaturization. Now, Penn State researchers have designed a 2D device that...
In experiments in mice, Johns Hopkins Medicine researchers say they have developed a way to successfully transplant certain protective brain cells without the need for lifelong anti-rejection drugs. A report on the research, published Sept. 16 in the journal...
If the idea of flying on battery-powered commercial jets makes you nervous, you can relax a little. Researchers have discovered a practical starting point for converting carbon dioxide into sustainable liquid fuels, including fuels for heavier modes of...
