Overflowing crater lakes carved canyons across Mars

Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research has found evidence that sometimes the lakes would take on so much water that they overflowed and burst from the sides of their basins, creating catastrophic floods that carved canyons very rapidly, perhaps in a matter of weeks.

Through mechanical measurements and mathematical modeling, they were able to use their findings to greatly enhance Affetto's range of emotional expression.

Orangutan populations are still declining rapidly, despite claims by the Indonesian Government that things are looking better for the red apes. Scientists criticize the use of inappropriate methods for assessing management impacts on wildlife trends. The researchers call for scientifically sound measures to be employed in order to ensure that wildlife monitoring provides reliable numbers.

Oldest evidence of dairying on the East Asian Steppe

Although dairy pastoralism once made Mongolian steppe herders successful enough to conquer most of Asia and Europe, the origins of this way of life on the East Asian steppe are still unclear. Now an international team of researchers has uncovered evidence that dairying arrived in Mongolia as early as 1300 BC through a process of cultural transmission rather than population replacement or migration.

More affordable and effective conservation of species

No one had reported seeing the strange creature -- a cross between a bear and a monkey -- since before the Great Depression. Then, this past summer, an amateur biologist stumbled upon the presumed-extinct Wondiwoi tree kangaroo while trekking through Papua New Guinea. The revelation underscored how little we still know about the natural world -- a major obstacle to conservation.

Laser tech could be fashioned into Earth's 'porch light' to attract alien astronomers

If extraterrestrial intelligence exists somewhere in our galaxy, a new study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light -- a beacon strong enough to attract attention from as far as 20,000 light years away.

Children's sleep not significantly affected by screen time, new study finds

As young people spend an increasing amount of time on electronic devices, the effects of these digital activities has become a prevalent concern among parents, caregivers, and policy-makers. Research indicating that between 50 percent to 90 percent of school-age children might not be getting enough sleep has prompted calls that technology use may be to blame. However, new research from the Oxford Internet Institute at the University of Oxford, has shown that screen time has very little practical effect on children's sleep.

Evidence of outburst flooding indicates plentiful water on early Mars

The presence of water on Mars has been theorized for centuries. Early telescopes revealed ice caps, and early astronomers noted channels that were hypothesized to be natural rivers or creature-created canals.

New material cleans and splits water

Researchers have developed a photocatalytic system based on a material in the class of metal-organic frameworks. The system can be used to degrade pollutants present in water while simultaneously producing hydrogen that can be captured and used further.

'Robust' corals primed to resist coral bleaching

A world-first study reveals that 'robust' reef-building corals are the only known organisms in the animal kingdom to make one of the 'essential' amino acids, which may make them less susceptible than other corals to global warming.

Editing nature: A call for careful oversight of environmental gene editing

Researchers makes the case for a new global governance to assure a neutral and informed evaluation of the potential benefits and risks of gene editing. The complex nature of these technologies, they write, requires a careful and judicious decision-making process that includes the local communities that would feel the biggest and most immediate effects.

Artificial intelligence bot trained to recognize galaxies

Researchers have taught an artificial intelligence program used to recognize faces on Facebook to identify galaxies in deep space. The result is an AI bot named ClaRAN that scans images taken by radio telescopes. Its job is to spot radio galaxies -- galaxies that emit powerful radio jets from supermassive black holes at their centres.

Immigration to the United States changes a person's microbiome

Researchers new evidence that the gut microbiota of immigrants and refugees rapidly Westernize after a person's arrival in the United States. The study of communities migrating from Southeast Asia to the US could provide insight into some of the metabolic health issues, including obesity and diabetes, affecting immigrants to the country.

High exposure to radio frequency radiation associated with cancer in male rats

The National Toxicology Program (NTP) concluded there is clear evidence that male rats exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones developed cancerous heart tumors, according to final reports released today.

Signs of interactive form of quantum matter observed

Researchers have, for the first time, isolated groups of a few atoms and precisely measured their multi-particle interactions within an atomic clock. The advance will help scientists control interacting quantum matter, which is expected to boost the performance of atomic clocks, many other types of sensors, and quantum information systems.

Breakthrough in treating paralysis

Three patients with chronic paraplegia were able to walk over ground thanks to precise electrical stimulation of their spinal cords via a wireless implant. In new research, Swiss scientists show that, after a few months of training, the patients were able to control previously paralyzed leg muscles even in the absence of electrical stimulation.
