Evidence Of Liquid Flowing Water On Mars?

TUCSON, Aug. 4 (UPI) — A NASA probe orbiting Mars has captured images suggesting the possibility of flowing water on the red planet during its warmest months, the space agency says. In observations recorded by the Mars Reconnaissance Orbiter, dark, finger-like features appear and extend down some Martian slopes during the planet’s late spring through […]

Oil-for-food Charges Baseless, Total Says

PARIS, Aug. 4 (UPI) — U.N. investigations into the oil-for-food program determined there was no corruption regarding Total’s activity in Iraq, the company said. An independent U.N. committee led by former U.S. Federal Reserve Chairman Paul Volker found in 2005 that thousands of companies were involved in illegal activity tied to the oil-for-food program for […]

Rare Crystals Found In Meteorite

TOHOKU, Japan, Aug. 3 (UPI) — Japanese researchers say they found opal-like crystals in a meteor that fell in Canada in 2000, the first extraterrestrial discovery of such unusual crystals. Reporting the find in the Journal of the American Chemical Society, scientists from Tohoku University said the crystals may have formed in the primordial cloud […]

Survey Tracks Beliefs About Memory

CHAMPAIGN, Ill., Aug. 3 (UPI) — A U.S. survey shows many people think memory is more powerful, objective, accurate and reliable than decades of scientific research suggest. In a telephone survey by University of Illinois researchers, 1,500 respondents were asked to respond to a series of statements about memory, a university release reported Wednesday. Almost […]

Skull Shows Early Dog Domestication

NOVOSIBIRSK, Russia, Aug. 3 (UPI) — A 33,000-year-old well-preserved canine skull from a cave in Siberia shows some of the earliest evidence of man’s domestication of the dog, researchers say. The skull is unlike those of modern dogs or wolves, researchers said; while the snout is similar in size to early, fully domesticated dogs from […]

New Sensor Has An ‘eye’ For Liquids

CAMBRIDGE, Mass., Aug. 3 (UPI) — Researchers at Harvard University say they have developed a new hand-held device that can quickly and accurately identify any unknown liquid. Scientists at the university’s School of Engineering and Applied Sciences used the chemical and optical properties of precisely nanostructured materials to identify liquids by their surface tension, a […]

Did Earth Once Have Two Moons?

SANTA CRUZ, Calif., Aug. 3 (UPI) — Earth may have once had two moons that collided, leaving an asymmetry in our companion’s shape that has long puzzled scientists, a U.S. researcher says. In an article published this week in Nature, Erik Asphaug, a planetary scientist at the University of California, Santa Cruz, suggests the two […]

Microbes Involved In Colon Health Studied

CHAMPAIGN, Ill., Aug. 2 (UPI) — U.S. researchers say they’re taking the first up-close look at some microbes that, although rare in the human gut, are fundamental to colon health. The so-called “hydrogenotrophic” microbes make up less than one-hundredth of 1 percent of the microbes that live in the colon but the bacteria and archaea […]

Oxygen Molecules Found In Deep Space

PASADENA, Calif., Aug. 2 (UPI) — NASA says instruments on board the Herschel Space Observatory have provided the first confirmed finding of oxygen molecules in space. While individual atoms of oxygen are common in space, particularly around massive stars, molecular oxygen, which makes up about 20 percent of the Earth’s atmosphere, has eluded astronomers until […]

No Change For Parking? No Problem

DORTMUND, Germany, Aug. 2 (UPI) — The frustration of finally finding a parking lot only to find you have no cash for the meter or machine may be a thing of the past, German researchers say. Scientists at the Fraunhofer Institute in Dortmund have developed a small radio-frequency identification chip that can be adhered to […]
