- How global warming created tiny horses
About 56 million years ago, a massive release of carbon dioxide heated the earth's surface by about 10 degrees over 175,000 years. Many mammals responded to this by shrinking.
- CERN researchers find flaw in faster-than-light measurement
Last year, scientists at CERN clocked neutrinos traveling faster than light, a speed widely regarded as physically impossible. Now they say the measurement might have been flawed.
- Sky actually falling, report scientists
A study of clouds over the last 10 years has found that their altitude has been declining, perhaps offsetting some global warming.
- NASA telescope detects massive cloud of 'buckyballs' hurtling through space
Space carbon spheres, known as buckyballs have recently been discovered by NASA astronomers. Scientists compare these tiny particle clouds to soccer balls, or oranges in a crate.
- Einstein vindicated? Neutrinos probably not faster than light.
Researchers last year thought they witnessed neutrinos traveling faster than light – overturning a fundamental tenet of Einstein's Theory of Special Relativity. Now, they're not so sure.
- NASA clocks 20 million mph winds near black hole
Scientists report record-breaking winds arising from a black hole called IGR J17091-3624. The wind's speed, 20 million miles per hour, would be expected in much larger black holes.
- Did CERN's neutrinos break the cosmic speed limit? Faulty wiring could be more likely.
Last year CERN researchers clocked neutrinos moving faster than light, in an apparent violation of the laws of physics. Now it seems that it was actually a bad measurement caused by a loose fiber optic cable.
- Why Einstein's special theory of relativity is probably still correct
Last year, European physicists measured a neutrino moving faster than light, in apparent violation of our current understanding of physics. Now it turns out it could be a bad measurement caused by a loose fiber optic cable.
- Loose cable could explain 'faster-than-light' neutrinos
Experiments conducted in Europe in September and November appeared to show neutrinos violating Einstein's theory of special relativity. But now scientists suspect it could be a faulty measurement caused by bad connection.
- Will men go extinct? New research says it's unlikely.
A recent study from the Whitehead Institute indicates that the male Y chromosome is unlikely to disappear, as was previously thought.
- NASA's dazzling northern lights launch aims to study 'space weather'
The two-stage suborbital rocket was part of a NASA-funded study into how the northern lights can affect signals from GPS satellites and other spacecraft.
- Black hole produces 'cosmic Category 5 hurricane'
A stellar-mass black hole, which is born when an extremely massive star collapses, typically contains about five to 10 times the mass of our sun.
- Elephants in Arabia? Scientists find prehistoric footprints.
The fossilized gigantic footprints detected in the Arabian dessert belong to a herd of elephants, scientists say. The seven-million-year-old discovery marks the world’s oldest evidence on how these ancient mammals lived.
- Climategate sequel? Scientist lies to get Heartland Institute documents.
Climate scientist, Peter Gleick, lied to acquire – then leak to the press – documents from the Heartland Institute, an organization that argues that global warming poses no threat.
- John Glenn's first spaceflight was fraught with risks and unknowns
Before Glenn completed three laps of Earth on Feb. 20, 1962, no American had spent more than 15 minutes in space.
- Hubble telescope spots new class of planet: a steamy 'waterworld'
The planet GJ 1214b is a watery planet covered in a thick, steamy atmosphere, a new study of Hubble data suggests.
- How scientists brought 30,000-year-old flower back to life
In what is being hailed as the oldest successful regeneration of a living plant, researchers from the Russian Academy of Sciences used cells from a 30,000-year-old plant buried in permafrost to create living seedlings.
- 300-million-year-old 'Chinese Pompeii' found buried under volcanic ash
Researchers near Wuda, China, have uncovered a tropical forest that was preserved by ash from a volcanic eruption during the early Permian era.
- Moon may contain magma, say scientists
Although the Earth's crust is still shifting, driven by the churning semimolten rock underneath it, researchers had thought the moon had cooled off much too long ago to still have any such tectonic activity.
- John Glenn reflects on NASA's space legacy 50 years after first orbit
On Feb. 20, 1962, Glenn piloted NASA's Mercury capsule, known as Friendship 7, three times around Earth, matching the groundbreaking achievement of the rival Soviet Union, which launched cosmonaut Yuri Gagarin into orbit 10 months earlier.
