New technique for finding life on Mars

Thu, 18 Jan 18 00:14:40 -0800

Miniaturized scientific instruments and new microbiology techniques successfully identified and characterized microorganisms living in Arctic permafrost -- one of the closest analogs to Mars on Earth. By avoiding delays that come with having to return samples to a laboratory for analysis, the methodology could also be used on Earth to detect and identify pathogens during epidemics in remote areas.

Viruses are everywhere, maybe even in space

Thu, 18 Jan 18 00:05:50 -0800

Viruses are the most abundant and one of the least understood biological entities on Earth. They might also exist in space, but as of yet scientists have done almost no research into this possibility. Portland State University biology professor Ken Stedman and colleagues are trying to change this through their article

Cheops' pyramid: Is there an iron throne in the newly discovered chamber?

Thu, 11 Jan 18 00:02:50 -0800

A recent exploration has shown the presence of a significant void in the pyramid of Khufu at Giza. A possible explanation of this space, interpreted as a chamber connected to the lower north channel and aimed to contain a specific funerary equipment is tentatively proposed. According to the Pyramid Texts, this equipment might consist of a Iron throne, actually a wooden throne endowed with meteoritic Iron sheets.

Scientist's work may provide answer to martian mountain mystery

Thu, 11 Jan 18 00:12:50 -0800

By seeing which way the wind blows, a University of Texas at Dallas fluid dynamics expert has helped propose a solution to a Martian mountain mystery. Dr. William Anderson, an assistant professor of mechanical engineering, co-authored a paper published in the journal Physical Review E that explains the common Martian phenomenon of a mountain positioned downwind from the center of an ancient meteorite impact zone.

Analyses on a small pebble found in south-west Egypt cast significant questions on a widely-held view about the primitive pre-solar dust cloud which our Sun, Earth and other planets were formed from. Researchers found exotic micro-mineral compounds in the 'Hypatia' stone that are not known to occur on Earth, elsewhere in our solar system, or in known meteorites or comets.

Mars: Not as dry as it seems

Wed, 20 Dec 17 00:02:40 -0800

Two new Oxford University papers have shed light on why there is no life on Mars. Although today's Martian surface is barren, frozen and inhabitable, a trail of evidence points to a once warmer, wetter planet, where water flowed freely -- and life may have thrived. The conundrum of what happened to this water is long standing and unsolved. However, new research published in Nature suggests that this water is now locked in the Martian rocks.

NASA calculated Philippines rainfall from Tropical Storm Kai-Tak

Tue, 19 Dec 17 00:04:20 -0800

Tropical Storm Kai-Tak moved through the central and southern Philippines over several days and weakened to a remnant low pressure area in the South China Sea. As it moved over the country, NASA found that the storm generated heavy amounts of rainfall.

Halogens can increase solar cell performance by 25 per cent

Tue, 19 Dec 17 00:11:20 -0800

New research from the University of British Columbia and the University of North Carolina at Chapel Hill shows that using halogens--a class of elements that include fluoride, bromine, chlorine and iodine--in a dye-sensitized solar cell can increase conversion efficiency by 25 per cent. The discovery could set the stage for improved solar cell designs.

A model of Mars-like protoplanets shed light on early solar activity

Thu, 14 Dec 17 00:12:50 -0800

A scientist from Siberian Federal University (SFU) and his colleagues from Austria and Germany constructed a physical and mathematical model of Mars- and Venus-sized planet formation. The team concluded that Mars had no chances to develop a thick atmosphere and biosphere. In the case of Venus it depended on solar activity: according to the scientists, it managed to keep its atmosphere due to the fact that young Sun was not very active. The study was published in Icarus.

Spanning disciplines in the search for life beyond Earth

Wed, 13 Dec 17 00:15:20 -0800

Following a gold rush of exoplanet discovery, the next step in the search for life is determining which of the known exoplanets are proper candidates for life -- and for this, a cross-disciplinary approach is essential.

Insights from NASA's Mars Atmosphere and Volatile Evolution, or MAVEN, mission about the loss of the Red Planet's atmosphere can help scientists understand the habitability of rocky planets orbiting other stars.

NASA shows new Tongan island made of tuff stuff, likely to persist years

Mon, 11 Dec 17 00:15:40 -0800

In late December 2014, a submarine volcano in the South Pacific Kingdom of Tonga erupted, sending a violent stream of steam, ash and rock into the air. The ash plumes rose as high as 30,000 feet (9 kilometers) into the sky, diverting flights. When the ash finally settled in January 2015, a newborn island with a 400-foot (120-meter) summit nestled between two older islands -- visible to satellites in space.

Insights on fast cockroaches can help teach robots to walk

Fri, 08 Dec 17 00:14:40 -0800

A study scientists from the University of Cologne have published in Frontiers in Zoology shows for the first time that fast insects can change their gait -- like a mammal's transition from trot to gallop. These new insights could contribute to making the locomotion of robots more energy efficient.

Tue, 21 Nov 17 00:12:40 -0800

A new study led by a University of Bristol earth scientist has shown that recently reported unexpected behavior on Titan, the largest moon of Saturn, is due to its unique atmospheric chemistry.

Previous evidence of water on mars now identified as grainflows

Mon, 20 Nov 17 00:12:40 -0800

Dark features previously proposed as evidence for significant liquid water flowing on Mars have now been identified as granular flows, where sand and dust move rather than liquid water, according to a new article published in Nature Geoscience by the USGS. These findings indicate that present-day Mars may not have a significant volume of liquid water. The water-restricted conditions that exist on Mars would make it difficult for Earth-like life to exist near the surface.

Salt pond in Antarctica, among the saltiest waters on Earth, is fed from beneath

Wed, 15 Nov 17 00:14:20 -0800

One of the saltiest bodies on Earth, an analog for what water might look like on Mars, is just one piece of a larger aquifer.

Winters on Mars are shaping the Red Planet's landscape

Fri, 27 Oct 17 00:16:00 -0700

Winter temperatures on the Red Planet sublimate carbon dioxide from a gas to a solid. These solid carbon dioxide blocks are then thought responsible for making gullies and furrows on Mars' landscape based on innovative lab experiments.

September 2017's intense solar activity viewed from space

Fri, 27 Oct 17 00:05:50 -0700

September 2017 saw a spate of solar activity, with the Sun emitting 27 M-class and four X-class flares and releasing several powerful coronal mass ejections, or CMEs, between Sept. 6-10. Solar flares are powerful bursts of radiation, while coronal mass ejections are massive clouds of solar material and magnetic fields that erupt from the Sun at incredible speeds.
