The crash of Virgin Galactic’s SpaceShip Two raises serious concerns about the future of commercial human spaceflight, including the imperatives of time and money that beset all who try to fly humans in space with existing technology,” according to a statement by Alex Roland, professor emeritus of history at Duke University and former NASA historian.

“Richard Branson has been famously secretive about the finances of Virgin… read more

“By 2040 or so, astronomers will have scanned enough star systems to give themselves a great shot of discovering alien-produced electromagnetic signals,” said Seth Shostak, Senior Astronomer at the SETI Institute, reports.

Shostak spoke at the NASA Innovative Advanced Concepts (NIAC) symposium on Feb. 6 at Stanford University.

He will also speak at the Contact conference on March 21–23… read more

Evidence that our Sun could release ‘superflares’ 1000x greater than previously recorded

Could release energy equivalent to a billion megaton bombs, potentially disastrous for life on Earth

Astrophysicists have discovered a stellar “superflare” on a star observed by NASA’s Kepler space telescope with wave patterns similar to those that have been observed in the Sun’s solar flares. (Superflares are flares that are thousands of times more powerful than those ever recorded on the Sun, and are frequently observed on some stars.)

The scientists found the evidence in the star KIC9655129 in the Milky Way. They suggest… read more

A research team from The Scripps Research Institute (TSRI), Mayo Clinic and other institutions has identified a new class of drugs that in animal models dramatically slows the aging process, alleviating symptoms of frailty, improving cardiac function, and extending a healthy lifespan.

They found two drugs — the cancer drug dasatinib (sold under the trade name Sprycel) and quercetin, a natural compound found… read more

The more science you know, the less worried you are about climate

May 30, 2012


Americans with higher levels of scientific and mathematical knowledge are more skeptical regarding the dangers of climate change than their more poorly educated fellow citizens, a U.S. National Science Foundation-funded study has found.

The results of the survey are especially remarkable as the researchers were doing so from the position that the “scientific consensus” (carbon-driven global warming is ongoing and extremely dangerous) is a settled fact, and the priority is… read more

Using 22 reference populations, the feature indicates what percent of a person’s ancestry comes from various regions around the world. The analysis includes DNA inherited from all ancestors on both sides of the family. The results… read more

‘The future might be a hoot’: how Iain M. Banks imagines Utopia

January 23, 2013


For 25 years, Scottish science fiction writer Iain M. Banks, author of the Culture Series, has been writing about a utopian post-scarcity civilization managed by artificially intelligent drones known as Minds, and preoccupied by artificial intelligence, games, and interactions with other civilizations.

In the latest novel published in October, The Hydrogen Sonata, a civilization known as the Gzilt are making preparations to Sublime — in… read more

How to kill cancer cells by starving them

July 15, 2013

University of Southampton researchers have discovered a novel way of killing cancer cells by leaves healthy cells undamaged, unlike traditional therapies such as radiotherapy.

Chris Proud, Professor of Cellular Regulation in Biological Sciences at the University of Southampton says: “Cancer cells grow and divide much more rapidly than normal cells, meaning they have a much higher demand for and are often starved of, nutrients and… read more

Worldwide annual solar PV installations will double by 2020, says report

November 10, 2013

Annual solar PV

Annual installations of new solar PV capacity will more than double in capacity by 2020, growing from a total 35.9 gigawatts (GW) in 2013 to 73.4 GW in 2020, according to a recent report from Navigant Research.

Despite waning government support, the threat of international trade wars, and high-profile bankruptcies, the solar photovoltaic (PV) market continues to grow, solar PV technology costs have steadily declined, and pathways… read more

‘NAFTA on Steroids’: secret agreements to censor the Internet

September 8, 2012


Negotiators from the U.S. and eight other Pacific Rim countries are meeting at a seclude resort in Leesburg, Viriginia, working out deals in the secretive Trans-Pacific Partnership trade agreement that could hamper free speech on the Internet, Common Dreams reports.

The negotiations began in 2007 and have been carried through by the Obama administration and several Pacific nations under conditions of “extreme secrecy” without press, public, or policymaker oversight.

Recent advances in precise editing of genomes now raise the possibility that fruit and other crops might be genetically improved without the need to introduce foreign genes, as in  genetically modified organisms (GMOs), say researchers writing in the Cell Press publication Trends in Biotechnology on August 13.

The notion is that “genetically edited” fruits might be met with greater acceptance than GMOs. This could mean “super bananas” that produce more vitamin… read more

The age of enhancement

March 5, 2013


Technology is starting to give us superpowers once reserved for comic-book heroes, Slate reports.

Human enhancement is happening all the time, largely through incremental improvements on existing technologies.

Wearable technology is taking off. Muscle suits are starting to look more plausible. The military is working on “Spider-Man suits” that let the wearer scale vertical walls.

A display that makes interactive 3D seem mind-bogglingly real

The Z Space display could be revolutionary for designers and animators, but might also inspire innovation in computer gaming and augmented reality
December 19, 2012


The “Z Space” display, developed by Californian company Infinite Z, tracks a user’s eye and hand movements and adjusts the 3-D image that he or she sees in real-time, MIT Technology Review reports.

The resulting effect is stunning. Unlike the 3-D video seen in a movie theater or on a 3-D TV, you can move your head around an object — to look it from… read more

Cook affirms Apple wearable-computing scenario

May 30, 2013


Speaking at the D11 Conference on Tuesday night in the opening tête-à-tête, Apple CEO Tim Cook offered muted praise for Google Glass but dismissed its mainstream appeal while calling wearable computing on your wrist “interesting” and “natural,” Jason Hiner writes on ZDNet.

Cook also predicted that the next generation of wearable computing will do more than just one thing such as activity tracking.

That kind… read more

Graphene micro-supercapacitors to replace batteries for microelectonics devices

Will power biomedical implants, active RFID tags, embedded micro-sensors, and flexible electronics
February 27, 2013


UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate miniature graphene-based supercapacitors — devices that can charge and discharge a hundred to a thousand times faster than standard batteries.

These micro-supercapacitors, made from a one-atom–thick layer of carbon, can be easily manufactured and readily integrated into small devices, such as next-generation pacemakers.

The new cost-effective fabrication method holds promise for the… read more
