Biomarkers reveal our biological age

August 20, 2008

Scientists at Max Planck Research Group for Stem Cell Aging in Ulm have identified a group of proteins that reveal the biological age of a person.

These biomarkers could be used in medicine to adapt therapies for older people to their individual biological age

A Sci-Fi Future Awaits the Court

September 22, 2005

At John Roberts’ confirmation hearings last week, there weren’t enough discussions about science fiction. Technologies that are science fiction today will become constitutional questions before Roberts retires from the bench. The same goes for technologies that cannot even be conceived of now. And many of these questions involve privacy.

Robot Guard-dragon Unveiled in Japan

November 13, 2002

The four-legged “guard dragon” robot sense smoke and alert its owners to a smoldering fire – via a howl or a mobile phone text message. The robot is one meter long, 80 centimeters high, 70 centimeters wide and weighs 40 kilograms. It can move at a top speed of 15 meters per minute – more than fast enough for a home robot designed to travel in confined, cluttered spaces, its… read more

Cell phones could double as night vision devices

May 5, 2010

Franky So, a University of Florida engineering researcher, has developed a nickel-sized imaging device that uses organic light-emitting diode technology (similar to that found in cell phone or laptop screens) for night vision.

Unlike night vision goggles, which are heavy and expensive, the device is paper-thin, light and inexpensive, making it a possible add-on to cell phone cameras, even eyeglasses, once it is enlarged.

The imaging device replaces… read more

Ayurvedic medicines laden with toxic heavy metals

August 27, 2008

21% of 193 traditional Indian Ayurvedic medicines bought on the Internet from US or Indian sources contained high amounts of lead, mercury or arsenic, with some heavy metals deliberately added, Boston University School of Medicine researchers have found.

Nanotubes refine computer memory

October 5, 2005

Nantero has succeeded in making circular wafers, 13 centimeters in diameter, that hold 10 gigabits of data and are ten times faster than flash memory.

Nantero calls its technology NRAM, nanotube-based, non-volatile random access memory.

The design involves suspending nanotube ribbons between points above a silicon chip, so that they form tiny bridges over electrodes lying below. When a charge is applied, the nanotube bridge curves… read more

Now Here’s a Really Big Idea

November 26, 2002

Darryl Macer, associate professor at the Institute of Biological Sciences at the University of Tsukuba in Japan, plans to create a human mental map — a database that would contain a log of every human idea.

By understanding which ideas are specific to certain cultures and which ones are universal, policy-makers can make more informed decisions about such agreements, Macer said.

1 in 4 households with cell phone, no landline

May 13, 2010

One in 4 households has a cell phone but no traditional landlines, up 2 percentage points from the first half of the year, according to data reported by the federal Centers for Disease Control and Prevention.

More than a third of people under age 35, including about half of those age 25 to 29, have only cell phones.

New master switch found in the brain that regulates appetite and reproduction

September 1, 2008

A master switch has been found in the brain of mice that controls both, and researchers at the Salk Institute for Biological Studies say it may work the same way in humans.

They suggest that variations in the TORC1 gene, which produces this master switch, could contribute a genetic component to obesity and infertility, and might be regulated with a novel drug.

Cyborg cells sense humidity

October 18, 2005

Living bacteria have been incorporated into an electronic circuit to produce a sensitive humidity gauge.

The gold nanoparticles-plated “cellborg” is “essentially a first step towards a biological computer, and would have many applications,” says Ravi Saraf, a chemist from the University of Nebraska, Lincoln.

Saraf speculates that similar devices could one day be made that take greater advantage of living organisms, perhaps even using bacteria’s energy systems to… read more

Software gambler takes on the tipsters

December 12, 2002

Software developed by Australian IT researcher Alan McCabe uses a neural network to learn which features of a team’s performance make them winners. The neural network is trained with match data obtained from a national bookmaker, such as a team’s current success rate and the points scored for and against them each week.

Kurzweil to discuss the brain at H+ Summit

May 20, 2010

Ray Kurzweil will keynote the H+ Summit, to be held June 12-13 at Harvard University, with a talk on “The Democratization of Disruptive Change.”

The talk will focus on understanding the brain: Where are we on the roadmap to this goal? What are the effective routes to progress — detailed modeling, theoretical effort, improvement of imaging and computational technologies? What predictions can we make? What are the… read more

Surprising twist in debate over lab-made H5N1

March 11, 2012

H5N1 virus (credit: Lennart Nilsson)

A researcher who created one of the H5N1 mutants and a leading U.S. health official say the threat has been blown out of proportion, offering what they said were clarifications and “new data” to better gauge the risk it presents.

Contrary to widespread reports, the researcher, Ron Fouchier of Erasmus MC in Rotterdam, the Netherlands, revealed that the virus made in his lab does not kill ferrets infected by… read more

Alternative Energy Trends and Implications for GCC Countries

September 6, 2008

Masdar City aims to be the first carbon neutral city in the world, using solar power, ecological architecture with passive energy balance and high energy efficiency, extensive recycling of waste, and a modern system of public transportation.

According to Masdar officials, the total projected investment for Masdar City is $22 billion, including $15 billion for Masdar renewable energy projects. People will start to move in by 2010 and the… read more

U.S. Military Wants to Own the Weather

November 1, 2005

The U.S. military’s space-based response to Katrina may have represented the embryonic stages of an integrated military/civilian weather reaction and control system.

For example, artificial ionized plasma patterns with megawatts of power using inexpensive microwave power sources could be used to heat specific regions of the atmosphere to control hurricanes.
