New NASA data challenges global warming theory

July 29, 2011

Particles in upper atmosphere slow down global warming, says NASA (credit: NASA)

NASA satellite data show the Earth’s atmosphere is allowing far more heat to be released into space than current computer models have predicted, according to a new study in the peer-reviewed science journal Remote Sensing.

Data from NASA’s Terra satellite shows that when the climate warms, Earth’s atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to… read more

Big Bang or Big Chill? The ‘Quantum Graphity’ theory

August 21, 2012

Is this the hidden granular structure from lensing-like effects? (Credit: James Q. Quach et al./

The start of the Universe should be modeled not as a Big Bang but more like water freezing into ice, according to a team of theoretical physicists at the University of Melbourne and RMIT University.

They suggest that by investigating the cracks and crevices common to all crystals — including ice — our understanding of the nature of the Universe could be revolutionized.

Serious Blow to Dark Matter Theories?

April 19, 2012

galactic_halo

The most accurate study so far of the motions of stars in the Milky Way has found no evidence for dark matter in a large volume around the Sun.

According to widely accepted theories, the solar neighborhood was expected to be filled with dark matter, a mysterious invisible substance that can only be detected indirectly by the gravitational force it exerts. But a new study by a team of… read more

Extending Einstein’s theory beyond light speed

October 11, 2012

Spacetime_curvature

University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light.

Einstein’s theory holds that nothing could move faster than the speed of light, but Professor Jim Hill and Dr Barry Cox in the University’s School of Mathematical Sciences have developed new formulas that allow for travel beyond this limit.… read more

Warp drive may be more feasible than thought, scientists say

September 18, 2012

warp-drive-starship

A warp drive to achieve faster-than-light travel — a concept popularized in television’s Star Trek — may not be as unrealistic as once thought, according to scientists at the 100 Year Starship Symposium, Space.com reports.

A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving fasterread more

23-Year old with terminal brain cancer hopes to be cryopreserved (UPDATE)

October 18, 2012

As we noted previously, Kim Suozzi, 23, has terminal brain cancer that is highly aggressive and growing rapidly in a location that makes surgery impossible, and her final wish is to be cryopreserved.

Alcor Life Extension Foundation announced Wednesday that it has offered to cryopreserve Kim at a reduced cost, with the staff donating their time for her cryopreservation.

“I learned about cryonics… read more

Tesla-Manufacturing

There is great concern about China’s real-estate and infrastructure bubbles.  But these are just short-term challenges that China may be able to spend its way out of.

The real threat to China’s economy is bigger and longer term: its manufacturing bubble.

Rising costs and political pressure aren’t what’s going to rapidly change the equation. The disruption will come from a set of technologies that are advancing at exponential… read more

‘Diamonds from the sky’ approach to turn CO2 into valuable carbon nanofibers

Decreasing CO2 to pre-industrial-revolution levels is the goal

A research team of chemists at George Washington University has developed a technology that can economically convert atmospheric CO2 directly from the air into highly valued carbon nanofibers for industrial and consumer products — converting an anthropogenic greenhouse gas from a climate change problem to a valuable commodity, they say.

The team presented their research today (Aug. 19) at the 250th National Meeting & Exposition of theread more

Mobileye Vision Technologies has created a self-driving system for an Audi A7 car, John Markoff writes in The New York Times.

It is capable only of driving in a single lane at freeway speeds, as well as identifying traffic lights and automatically slowing, stopping and then returning to highway speeds.

But by blending advanced computer-vision techniques with low-cost video cameras, the company is… read more

The Milky Way galaxy is at least 50 percent larger than is commonly estimated, according to new findings that reveal that the galactic disk is contoured into several concentric ripples.

The research, conducted by an international team led by Rensselaer Polytechnic Institute Professor Heidi Jo Newberg, revisits astronomical data from the Sloan Digital Sky Survey which, in 2002, established the presence of a bulging ring of stars beyond the… read more
