“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, Space.com 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

Tel Aviv University researchers have developed a computer algorithm that predicts which genes can be “turned off” to create the same anti-aging effect as calorie restriction*. The findings, reported in Nature Communications, could lead to the development of new drugs to treat aging.

“Most algorithms try to find drug targets that kill cells to treat cancer or bacterial infections,” says Keren Yizhak, a doctoral student in Prof.… read more

Cook affirms Apple wearable-computing scenario

May 30, 2013

FaceTime-Anders-Kjellberg

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

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

Scientists at the Universities of Sheffield and Sussex are embarking on an ambitious project to produce the first accurate computer models of a honeybee brain in a bid to advance our understanding of Artificial Intelligence (AI) and how animals think.

The team will build models of the systems in the brain that govern a honeybee’s vision and sense of smell. Using this information, the researchers… read more

Domestic drones and their unique dangers

March 31, 2013

AR Drone 2.0

The use of drones by domestic U.S. law enforcement agencies is growing rapidly, both in terms of numbers and types of usage, blogger Glenn Greenwald writes in The Guardian.

A short summary of Greenwald’s comprehensive article:

  • The belief that weaponized drones won’t be used on U.S. soil is patently irrational. Police departments are already speaking openly about how their drones “could be equipped to carry

Drug laws are ‘worst case of scientific censorship in modern times’

June 17, 2013

brain_psilocybin

Outlawing psychoactive drugs amounts to the worst case of scientific censorship in modern times, leading scientists have argued.

UN conventions on drugs in the 1960s and 1970s have not only compounded the harms of drugs but also produced the worst censorship of research for over 300 years. This has set back research in key areas such as consciousness by decades and effectively stopped the investigation of promising… read more

Green tea extract blocks formation of amyloid plaques in Alzheimer’s disease

March 8, 2013

green_tea_alzheimer

Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain.

U-M Life Sciences Institute faculty member Mi Hee Lim and an interdisciplinary team of researchers used green tea extract to control the generation of metal-associated amyloid-β aggregates associated with Alzheimer’s disease in the lab.

The specific molecule… read more

“The rise of the drone is not a case of technology run amok. It is the result of human decision: of political calculation and, too often, strategic evasion,” says author Fred Kaplan in MIT Technology Review.

“Judging from its expanded use over the past five years, the drone’s chief danger is that it makes war too easy — so easy that commanders, including the commander-in-chief, can fool themselves… read more

How science can build a better you

November 4, 2012

How far would you go to modify yourself using the latest medical technology?

In a New York Times article Saturday, author and broadcaster David Ewing Duncan offers a partial checklist of cutting-edge medical-technology therapies now under way or in an experimental phase that might lead to future enhancements, including:

Present:

  • supermemory or attention pill
  • cochlear implant to improve hearing
  • brain-boosting neuro-feedback and

Meet Zoe: a digital talking head. She can express a range of human emotions on demand with “unprecedented realism” and could herald a new era of human-computer interaction, according to researchers at Toshiba’s Cambridge Research Lab and the University of Cambridge’s Department of Engineering, who created her.

Zoe, or her offspring, could be used as a visible version of Siri, as… read more

Replacing a defective gene with a correct sequence to treat genetic disorders

NewsImage-GeneRepair

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

The findings, described in the March 30 issue of Nature Biotechnology, offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with… read more
