A researcher harvested two stalagmites—one 4,000 years old, the other 25,000 years old—from a cave to analyze them for isotopic and trace element variations in an effort to build a 4,000-year paleo-rainfall record.
Scientists have unearthed new evidence about ancient dry spells that suggest the future could bring even more serious water shortages.
Scientists are reporting an advance in solving the mystery of why hot dogs develop an unpleasant tough texture when vegetable oils pinch hit for animal fat.
Vesta appears in a splendid rainbow-colored palette in new images obtained by the Dawn spacecraft. The colors, assigned by scientists to show different rock or mineral types, reveal Vesta to be a world of many varied, well-separated layers and ingredients.
Using clever but elegant design, chemists have synthesized tiny, molecular cages that can be used to capture and purify nanomaterials.
In this month's Cell Podcast, we learn about why structural biologists need no longer fear the membrane, with Doug Rees (Tirado-Lee et al. and Special Reviews Collection) (0:00), why...
A team is developing a portable device to locate people in dangerous situations. It incorporates all signals of opportunity, such as GPS and WiFi. It also incorporates RF signals.
Accelerated melting of two outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result of an increase in temperatures in the tropical Pacific Ocean.
The human genome and the endowments of genes in other animals and plants are like a deck of poker cards containing a “wild card” that in a genetic sense introduces an element of variety and surprise that has a key role in life.
Specially prepared light waves interact with very small numbers of atoms in ultra-thin fiber glass, which makes it possible to build detectors that are extremely sensitive to tiny trace amounts of a substance.
A paper warns that there are limits on how smart humans can get, and any increases in thinking ability are likely to come with problems.
Bedbugs are able to inbreed with close relatives and still produce generally healthy offspring. This means that if just a few bedbugs survive in a building after treatment, they repopulate quickly.
Researchers have found optimal configurations for creating 3D geometric shapes which may lead to advances from drug-delivery containers to 3D sensors and electronic circuits.
Paul Loprinzi from Bellarmine Univ. studied how sleep and exercise interact and impact health and to see if exercise could be used as a way to help improve sleep patterns.
