Ethical Concerns on Face Transplant Grow

December 8, 2005

American scientists are expressing increasing concerns that the world’s first partial face transplant, performed in northern France on Nov. 27, may have been undertaken without adequate medical and ethical preparation.

Biology to make mini machines

February 16, 2003

Computers of the future will be built not by factory machines, but by living cells such as bacteria.

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.

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.

Real World Robots

March 24, 2003

The Age of Robots might finally have arrived. Robots are doing real jobs alongside humans — in homes, hospitals and on the battlefield

How to Create Quantum Superpositions of Living Things

September 10, 2009

Max-Planck-Institut fur Quantenoptik researchers have proposed an experiment to create a quantum superposition of a virus to “address fundamental questions, such as the role of life in quantum mechanics,and differences between many-world and Copenhagen interpretations.”

The experiment will first involve storing a virus in a vacuum and then cooling it to its quantum mechanical ground state in a microcavity. Zapping the virus with a laser then leaves it in… read more

‘Twisting’ light packs more information into one photon

March 24, 2008

University of Illinois at Urbana-Champaign researchers have managed to to make a photon carry 1.63 bits, and theoretically 2 bits, by using twisted light (by giving it orbital angular momentum).

The technique could help maximize the amount of information carried per unit of energy in satellite communications.

Doomsday vault to avert world famine

January 13, 2006

A “doomsday vault” designed to hold around 2 million seeds, representing all known varieties of the world’s crops, is being built 1000 kilometers from the North Pole by the Norwegian government to safeguard the world’s food supply against nuclear war, climate change, terrorism, rising sea levels, earthquakes and the ensuing collapse of electricity supplies.
