Mine robot bogged down in mud in West Virginia rescue

January 4, 2006

A robot designed to search mines during emergencies was bogged down by mud earlier Tuesday, and was temporarily out of service in efforts to locate 13 miners trapped in a West Virginia mine.

The rescue robot, developed for the federal Mine Safety and Health Administration, is 30 inches wide, 50 inches tall and was designed to find possible escape routes for those trapped inside and determine whether it’s safe… read more

Pythagoras Solar turns windows into panels of energy

June 28, 2011

Pythagoras Solar

Pythagoras Solar, a start-up based in San Mateo, California, is working on creating “solar windows” that could generate power for office buildings and shield offices from sunlight, thus reducing air conditioning costs, according to the San Francisco Chronicle.

Thin horizontal rows of silicon cells embedded between dual panes of glass catch light from above. And through a trick of optics, the window blocks direct sunlight from… read more

Undercover genes slip into the brain

March 24, 2003

A molecular Trojan horse that can slip past the brain’s defences has proved to be very effective at delivering genes, drugs and other compounds to the brains of primates. It could be used to treat a host of brain disorders, from Parkinson’s to epilepsy.

After Hubble Repair, New Images From Space

Astronomers on Wednesday unveiled dramatic new pictures and observations from the retrofitted Hubble Space Telescope.

Therapeutic cloning used to treat brain disease in mice

March 23, 2008

An international team has restored mice with a Parkinson’s-like disease back to health, using neurons made from their own cloned skin cells.

Sloan-Kettering Institute and RIKEN Center (Japan) researchers created embryonic stem (ES) cell lines from the cells, coaxed them to develop into neurons, and transplanted them back into the mice, which got significantly better, without suppressing their immune systems to allow the grafts to survive.

Stem cell experts seek rabbit-human embryo

January 13, 2006

British scientists are seeking permission to create hybrid embryos in the lab by fusing human cells with rabbit eggs. If granted consent, the team will use the embryos to produce stem cells that carry genetic defects, in the hope that studying them will help understand the complex mechanisms behind incurable human diseases.

To make a hybrid embryo, a human skin cell would be taken from a person with motor… read more

Dream code: Programming languages for quantum computers are now being written

April 4, 2003

Researchers are already trying to work out how to write programs for almost non-existent quantum computers, in the belief that learning how to do so might help engineers to design the computers in useful ways.

Sending science down the phone

September 16, 2009

Groups of researchers may be able to quickly and easily build up and share maps of cases of a disease (or other projects) and analyze patterns that emerge, using EpiCollect, a new smartphone app developed by Imperial College London researchers that allows a scientist or member of the public to collect and record data, photos and videos and send them to a central web-based database.

‘Tree of life’ for 2.3 million species released

A “Wikipedia” for evolutionary trees
September 21, 2015

This circular family tree of Earth’s lifeforms is considered a first draft of the 3.5-billion-year history of how life evolved and diverged. (credit: Duke University)

A first draft of the “tree of life” for the roughly 2.3 million named species of animals, plants, fungi and microbes — from platypuses to puffballs — has been released.

A collaborative effort among eleven institutions, the tree depicts the relationships among living things as they diverged from one another over time, tracing back to the beginning of life on Earth more than 3.5 billion years ago.

DOOMSDAY FEARS SPARK LAWSUIT

March 28, 2008

The builders of CERN’s Large Hadron Collider are being sued in federal court over fears that the experiment might create globe-gobbling black holes or never-before-seen strains of matter that would destroy the planet.

The doomsday scenarios include runaway microscopic black holes, strangelets, and magnetic monopoles.

Is This Life?

January 25, 2006

In the past decade, individual labs have met 10 of 12 proposed requirements for creating a “protocell,” but in quite different ways. With only two steps remaining, they might achieve a synthetic organism within this decade.

Neural networks study reveals hierarchical structure

July 13, 2011

Researchers at Tel Aviv University’s School of Electrical Engineering have developed a new kind of a lab-on-a-chip platform that may help neuroscientists understand one of the deepest mysteries of our brain: how neuronal networks communicate and work together.

Using network engineering techniques, the scientists cultured different sized networks of neuronal clusters. Once they looked at these groups, they found rich and surprising behaviors that could… read more

Planning for the Next Net War

April 18, 2003

The Department of Defense is introducing network-centric warfare in Iraq, using “real-time video images to target missiles in flight, wireless PDAs to connect with stateside medical records from the battlefield, and virtual- reality simulations to provide just-in-time delivery of material to front-line troops.”

Future war technologies will include information from sensors reporting such things as the shape of radar waveforms, acoustic signals and seismic analysis, used to immediately notify… read more

Stimulating Sight: Retinal Implant Could Help Restore Useful Level Of Vision To Certain Groups Of Blind People

September 24, 2009

(Shawn Kelly)

Scientists from MIT and other organizations have developed a new prototype of a less invasive retinal prosthesis to be implanted behind the retina to take over the function of lost retinal cells by electrically stimulating retinal neurons.

A camera mounted on a pair of glasses sends images to a microchip attached to the eyeball. The glasses also contain a coil that wirelessly transmits power to receiving coils surrounding the… read more

Bugs provoke the immune system into fighting cancer

April 2, 2008

Advaxis has developed a method of deliberately infecting people with a harmless version of the bacteria that cause listeriosis to to kick-start the body’s immune system and increase its ability to destroy tumors.
