It seems like scientists are all about immortality these days. It's not just plants and people that are getting the treatment, though. A team of Harvard engineers are developing a way of producing color that could produce paint that never fades, and displays that never go dark.
Evolutionary and developmental biologists have discovered that sea anemones display a genomic landscape with a complexity of regulatory elements similar to that of fruit flies or other animal model systems. This suggests that this principle of gene regulation is already 600 million years old and dates back to the common ancestor of human, fly and sea anemone.
Why were Neanderthals replaced by anatomically modern humans around 40,000 years ago? One popular hypothesis states that a broader dietary spectrum of modern humans gave them a competitive advantage on Neanderthals. Geochemical analyses of fossil bones seemed to confirm this dietary difference. Indeed, higher amounts of nitrogen heavy isotopes were found in the bones of modern humans compared to those of Neanderthals. However, these studies did not look at possible isotopic variation of nitrogen isotopes in the food resource themselves.
An ancient civilization built the famous, stone-hewn city of Petra so that the sun would illuminate their sacred places like celestial spotlights, a new study says.
New research on the DNA on ancient bones from domesticated chickens confirms Columbus beat Polynesians to South America, say researchers.
Efforts are under way to identify ancient human remains found on a Cornish beach.
Archaeologists have found the 3,200-year-old skeleton of a man with a spreading form of cancer, the oldest example so far of a disease often associated with modern lifestyles, scientists said Monday.
British scientists have successfully revived mosses that have been frozen under the Antarctic ice for 1,500 years.
For millions of years, nine species of large, flightless birds known as moas (Dinornithiformes) thrived in New Zealand. Then, about 600 years ago, they abruptly went extinct. Their die-off coincided with the arrival of the first humans on the islands in the late 13th century, and scientists have long wondered what role hunting by Homo sapiens played in the moas’ decline.
Without elephants, the ancient Library of Alexandria might not have existed. Every war has, as a byproduct, cultural and technological innovation: in our world, the US Civil War led to medical advancements and the Cold War put us in space. In the classical era, it was the race to build elephant armies that changed the world.
The more muscle mass older Americans have, the less likely they are to die prematurely, new research shows. The findings add to the growing evidence that overall body composition -- and not the widely used body mass index, or BMI -- is a better predictor of all-cause mortality. "In other words, the greater your muscle mass, the lower your risk of death," said the study's co-author.
The venom of earth's more exotic and dangerous creatures has long been used as medicine. Though snails aren't typically thought of as a source, one type, the cone snail, injects its prey with paralyzing poison 100 times as powerful (in terms of numbing pain) as morphine and gabapentin without the addictive qualities.
One of agricultural biotechnology’s great success stories may become a cautionary tale of how short-sighted mismanagement can squander the benefits of genetic modification.
Sunlight plus a common titanium pigment might be the secret recipe for ridding pharmaceuticals, pesticides and other potentially harmful pollutants from drinking water. Scientists combined several high-tech components to make an easy-to-use water purifier that could work with the world's most basic form of energy, sunlight, in a boon for water purification in rural areas or developing countries.
New research in Geophysical Research Letters examines earthquake swarms caused by mounting volcanic pressure which may signal an imminent eruption. The research team studied Augustine Volcano in Alaska which erupted in 2006 and found that precursory earthquakes were caused by a block in the lava flow.
The surface of Mercury is shrinking faster than previously thought, photos from a NASA spacecraft orbiting the tiny planet reveal.
After years of searching, planetary scientists think they may finally have spotted waves rippling on the seas of Titan, Saturn’s largest moon. If confirmed, this would be the first discovery of ocean waves beyond Earth.
Scientists are using a promising new theory to track down hidden water both on Earth – where fresh water is becoming dangerously scarce in some regions – and in the quest for life on the red planet, Mars.
