Professor Ralph Keeling of Scripps Institute is worried. In fact, he's very worried. According to the data Keeling has meticulously collected since 1989 the world is running out of breathable air—and the rate that it's losing oxygen is now on the v

An accurate ionization lifetime is critical to understanding the amount of carbon released from comets, said Jeff Morgenthaler, senior scientist at PSI. A shorter lifetime suggests that the carbon content of some comets may be lower than previousl
The extremely-rare lunar eclipse which coincided with 2010's winter solstice for the first time in over 400 years happened just a few hours ago. NASA claims the last time these astronomical events took place at the same time was on Dec. 21, 1638,
According to Frank Fenner, emeritus professor of microbiology at the Australian National University, you won't live to see 2100—even if you're still in excellent health. In fact, no one else will be around to ring in the New Year 90 years from now
The sun is worrying scientists. They've been quietly asking each other what's wrong with it. They've been asking that question for some time. Now their question's about to be answered. The giant is about to awaken from its abnormal slumber and sc
Launched on Sept. 5, 1977, Voyager 1 crossed the termination shock in December 2004 into the heliosheath. Scientists have used data from Voyager 1's Low-Energy Charged Particle Instrument to deduce the solar wind's velocity. When the speed of th
In 2008 mathematician and author Michael S. Schneider put together a video explaining how mathematics used by Ancient Egyptians is identical to the math used in computers today. The Ancient Egyptians figured out how to do multiplication without me
If a superconductor is brought into contact with a ferromagnetic material, the Cooper pairs are broken up along the shortest path and the superconductor becomes a normal conductor. Cooper pairs cannot continue to exist in a singlet state in a fe
n a paper they prepared for the Journal of Geophysical Research (JGR), Schrijver and Title broke down the Great Eruption into more than a dozen significant shock waves, flares, filament eruptions, and CMEs spanning 180 degrees of solar longitude and
From the day that the existence of antimatter was first postulated, the question that haunted cosmologists became: why didn't antimatter annihilate all matter? Most scientists studying the creation of the universe believe that equal amounts of both
Many of the flight applications at the heart of our business model – orbital debris removal, satellite servicing, cargo flights to the Moon and Mars, and ejecting fast probes to the outer solar system – have required that the propulsion system achiev
The cloud starts from a point about 93 billion miles from the Sun and stretches for around three light years and contains billions of comets, most of them small and hidden.
Penrose takes issue with the inflationary picture (inflation after a big bang) and in particular believes it cannot account for the very low entropy state in which the universe was believed to have been born – an extremely high degree of order that
Bart Weetjens talks about his extraordinary project: training rats to sniff out land mines. He shows clips of his "hero rats" in action, and previews his work's next phase: teaching them to turn up tuberculosis in the lab.
A variety of MNMs can have beneficial applications in construction that encompass superior structural properties, functional paints and coatings, and high-resolution sensing/actuating dev
It would therefore be mistaken to interpret our assessment of the Bem experiments as an attack on research of unlikely phenomena; instead, our assessment suggests that something is deeply wrong with the way experimental psychologists design their stu
The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and "fixing" or storing carbon.
One of the world's greatest mysteries--the Devil's Triangle--has been solved by Professor Joseph Monaghan and honor student David May at the Monash University in Melbourne, Australia. The two brainstormed an amazing theory that they tested and prov
"As Earth orbits the sun, it creates a sort of shell or depression that dust particles fall into, creating a thickening of dust – the tail – that Earth pulls along via gravity," explains Werner. "In fact, the tail trails our planet all the way aro

The team found that when the thalloid liverwort was colonised by the fungi, it significantly enhanced photosynthetic carbon uptake, growth and asexual reproduction, factors that had a beneficial impact on plant fitness.
Subsequent discoveries of many more objects created instant buzz not only because they helped demote Pluto from a planet to just-another-Kuiper-Belt-object, but because of the Kuiper Belt's mysterious diversity. These bodies sport not just coats of
In recent months, the sun has entered an active period of its 11-year solar weather cycle after an extended lull in activity. Several powerful flares have erupted from the sun's surface in recent weeks. The Solar Dynamics Observatory and several ot
A peanut-shaped comet was spewing hundreds of tons of fluffy ice chunks every second as a NASA spacecraft swung by it two weeks ago. “To me, this whole thing looks like a snow globe that you’ve simply just shaken,” Peter H. Schultz, a Brown Unive
This section explains in basic terms the principals that are used to create the refrigeration effect. Graphics and animation's are used in an attempt to make it easy to understand the concepts involved.
In her most recent work, Grummt and her co-workers have shown for the first time that epigenetic regulation and regulation by noncoding RNAs interact.
This may be the first time the common way of making a black hole has been observed," said co-author Abraham Loeb, also of the Harvard-Smithsonian Center for Astrophysics. "However, it is very difficult to detect this type of black hole birth
