Mining the Web for Feelings, Not Facts

August 24, 2009

An emerging field known as sentiment analysis, fueled by social networking, is taking shape around one of the computer world’s unexplored frontiers: translating human emotions into hard data, which could eventually transform the experience of searching for information online.

Unlikely graphene-nanotube combination forms high-speed digital switch

August 4, 2015

Hair-like boron nitride nanotubes intersect a sheet of graphene to create a digital switch. (credit: Michigan Tech, Yoke Khin Yap)

By themselves, graphene is too conductive while boron nitride nanotubes are too insulating, but combining them could create a workable digital switch — which can be used for controlling electrons in computers and other electronic devices.

To create this serendipitous super-hybrid, Yoke Khin Yap, a professor of physics at Michigan Technological University, and his team exfoliated (peeled off) graphene(from graphite) and modified the material’s surface… read more

Short-term stress can affect learning and memory

March 12, 2008

University of California at Irvine researchers have found that short-term stress lasting as little as a few hours can impair brain-cell communication in areas associated with learning and memory.

The acute-stress-activated selective corticotropin molecules released hormones (CRH), which disrupted the process the brain uses to collect and stores memories.

In rat and mouse studies, the researchers found that the release of CRH in the hippocampus led to rapid… read more

The Singularity Is Near ranks in top-selling science and tech books in 2005

December 17, 2005

After an extended run as #1 on the science, technology, and philosophy lists since its publication, Ray Kurzweil’s The Singularity Is Near: When Humans Transcend Biology ends 2005 as the fourth best-selling science book in 2005, even though published late in the year (September 26).

The book was also selected by the Amazon editors as #6 on their “Best Books of 2005: Science” list.… read more

House passes ban on human cloning

February 28, 2003

After a lengthy debate on science and human life, the House on Thursday passed a bill endorsed by President Bush that would ban human cloning and sentence violators to prison and fines as high as $1 million.

Tumors Feel The Deadly Sting Of Nanobees

September 1, 2009

Washington University School of Medicine researchers have attached the peptide Melittin, a major component of bee venom, to nano-sized spheres they call “nanobees”
for injection into tumors.

Melittin is strongly attracted to cell membranes, where it can form pores that break up cells and kill them. The results suggest that nanobees could lessen the growth and size of established cancerous tumors and also act at early stages to prevent… read more

Put young children on DNA list, urge police

March 17, 2008

Primary school children should be eligible for the DNA database if they exhibit behavior indicating they may become criminals in later life, according to Britain’s most senior police forensics expert.

Vitamin D May Lower Some Cancer Risk

December 29, 2005

There is growing evidence that vitamin D helps protect against colorectal cancer, and now a group of researchers who have long studied the vitamin say the same is true for breast cancer and ovarian cancer.

The researchers recommend 1,000 international units (IU) of vitamin D daily. Current recommendations call for people between the ages of 1 and 50 to consume 200 IU of vitamin D daily, with 400 IU… read more

Bone marrow cells can become heart cells

March 14, 2003

Researchers have detected the first evidence that cells originating in the bone marrow can form new heart tissue in human adults and this suggests the technique could prove useful for mending and regenerating damaged heart tissue.

Secrets of the centenarians: Life begins at 100

September 8, 2009

Researchers who study the oldest people have made a surprising discovery that presents a less bleak vision of the future than many anticipate: people who break through the 90-plus barrier represent a physical elite, markedly different from the elderly who typically die younger than them.

Far from gaining a longer burden of disability, their extra years are often healthy ones.

First 3-D view of anti-cancer agent

March 20, 2008

Indiana University and Purdue University researchers used X-ray crystallography to create the first 3D image showing how the chemotherapy agent bleomycin targets and binds to DNA.

The research may allow for developing a less toxic version. Bleomycin is used in a standard treatment for testicular cancer, but it causes lung damage, so currently it isn’t used against many other cancers.

A powerful microscale actuator for microrobotics and drug delivery

Can deliver a force 1000 times greater than human muscle of the same weight
December 18, 2012

transforms from a metal into an insulator at a critical temperature near room temperature

A powerful new microscale actuator that can flex like a miniature beckoning finger has been developed by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley.

It is based on a material that expands and contracts dramatically in response to a small (15 degrees C) temperature variation. It is smaller than the width of a human hair and… read more


January 10, 2006

The new robot designs for space exploration are part of a broader shift toward a vision of robots that are partners, not simply remote-controlled probes.

At the Computer Science and Artificial Intelligence Laboratory at MIT, robots are developing the skills they’ll need to be useful to people. The Mertz robot recognizes faces and distinguishes one person from another. Obrero, a mechanical arm, has a touch so sensitive it can… read more

Researchers Invent Computers That ‘Pay Attention’ to Users

March 31, 2003

Researchers from the Human Media Lab at Queen’s University in Kingston, Ontario have developed a new concept that allows computers to pay attention to their users’ needs.

One of the main underlying technologies is an eye contact sensor that allows each device to determine whether a user is present and whether that user is looking at the device. This allows devices to establish what the user is attending to,… read more

Google Releases News-Reading Service

September 15, 2009

Google introduced Monday an experimental news hub called Fast Flip that allows users to view news articles from about three dozen major publishers and flip through them as quickly as they would the pages of a magazine.

The mobile version of Google Fast Flip is available for the iPhone and Android devices by simply navigating to the Google Fast Flip homepage on your phone.
