An 11-year old boy, Zhenya Salinder, discovered a well-preserved mammoth carcass in the permafrost of Northern Siberia, 3,500 km northeast of Moscow in Sopochnaya Karga. A team of experts from the St Petersburg Zoology Institute excavated the mammoth in five days, extracting it from the frozen mud. They sent it to Moscow for further study. […]

MIT Team Uses Carbon Nanotubes to Draw Gas Sensors

drawing-carbon-nanotubes

A team of MIT chemists revealed how they developed a method for drawing gas sensors on paper using a tailor-made, super-conductive carbon nanotube pencil. The scientists published their findings in the German journal Angewandte Chemie. Electrically charged carbon nanotubes, about 50,000 times thinner than human hair, make for great sensors. When a gas molecule disturbs […]

Cosmic Spiral Around Red Giant Star R Sculptoris Could Elucidate Stellar Evolution

unexpected spiral structure in the material around the old star R Sculptoris

R Sculptoris, an elderly star, located 1,500 light-years from Earth, has been observed in the final stages of stellar life, slowly shedding the outer layers of its atmosphere. There are intensely high temperatures at the star’s core, which create a powerful stellar wind that drive these layers out. They usually accumulate into planetary nebulae over […]

New Infrared Obscurants Will Cloak Battlefields in Greener Fog of War

New Infrared Obscurants

Obscurants, which are basically metallic dust clouds, have been in use for years in order to protect troops from heat-seeking missiles. These obscurants have never been environmentally friendly or easy to control. The army has just handed out financial awards to private companies in hopes that they might develop better obscurants. Most large military hardware […]

Humans Are Less in Control of Their Brains Than Previously Thought

brain-processes-visual-information

Most of the actions that people take for granted are the result of a set of complex decisions that the brain deals with. The decisions about how to aim the body, how hard to hold handles, and how to raise cups are something that no one often consciously thinks of, yet the brain does all […]

A new study of fossils in New Zealand has discovered that cloning dinosaurs or organisms that have been extinct for millions of years is highly improbable, since the half-life of DNA is 521 years. The scientists published their findings in the journal Proceedings of the Royal Society B. After cell death, enzymes start to break […]

Distant Exoplanets form Planetary Syzygy Celestial Alignment

exoplanetary-system

Astronomers have discovered that two exoplanets are overlapping in the skies as they cross their star. The phenomenon is new enough that it doesn’t have a name, but it’s related to a syzygy, which is when a straight line configuration of three celestial bodies is formed in a gravitational system. Astronomers used data from the […]

Graphene Membranes May Help Reduce Carbon Dioxide Emissions

Graphene membranes may lead to enhanced natural gas production

A new study shows that ultraviolet-induced oxidative etching can create pores in micrometer-sized graphene membranes, which effectively separates gas molecules of different sizes. Engineering faculty and students at the University of Colorado Boulder have produced the first experimental results showing that atomically thin graphene membranes with tiny pores can effectively and efficiently separate gas molecules […]

Cutting Food Losses Could Feed an Additional Billion People

Halving the food losses

A newly published study in Science of the Total Environment is the first to evaluate the impact of food losses and its relationship to resources on a global scale, finding that an additional one billion people can be fed from our current resources if the food losses could be halved. More efficient use of the […]

Astronomers Discover Star Orbiting the Black Hole at Center of the Milky Way

astronomers discover star racing around black hole

A team of scientists discovered a star called S0-102 that orbits the black hole at the center of our Milky Way galaxy in 11.5 years. This is the shortest known orbit of any star near this black hole and with future measurements it may provide scientists with the opportunity to test Einstein’s theory of general […]

Stanford Scientists Examine How UV Radiation Affects the Protective Functions of Human Skin

UV exposure makes human tissue more likely to tear under pressure

Scientists at Stanford University examined how varying doses of UVB radiation changes the protective functions of human skin, finding that beyond DNA damage and cancer risk, UV rays also change the way the outermost skin cells hold together and respond to strain. Reinhold Dauskardt, professor of materials science and engineering at Stanford, has been studying […]
