Museum curators and researchers who need to view historical artefacts or works of art in museums and galleries such as the Louvre, the Uffizi and London’s National Gallery, should be able to save on their plane and train fares thanks to a unique project being undertaken by computer scientists at the University of Southampton.

The project, known as SCULPTEUR, involves building an advanced database to store three-dimensional representations of museum artefacts and works of art together wi

When members of two species compete directly with each other, scientists believe the one that rolls with the evolutionary punches and adapts most quickly has the upper hand. But new evidence suggests that in relationships that benefit both species, the one that evolves more slowly has the advantage.

“The idea that has been dominant for the last couple of decades is that when two species co-evolve, they try to outrun each other,” said Carl Bergstrom, a University of Washington assistant zoolo

In results presented this week at the 2003 meeting of the American Astronomical Society (AAS) in Seattle, astrophysicist Greg Aldering and colleagues report that their supernova factory project has discovered an unprecedented 34 new supernovae in its first year. The accomplishment would not have been possible without the National Science Foundation (NSF) – supported high performance wireless network link to Palomar Observatory. “This has been the best rookie year for any supernova search pro

A new type of star has been discovered lurking as a low mass component in a very compact binary star system.

Astronomers Steve B. Howell of the University of California, Riverside and Tom Harrison of New Mexico State University, Las Cruces, announced today at the American Astronomical Society Meeting in Seattle, Wash., that they have confirmed the existence of a new variety of stellar end-product. This previously unknown type of star has some properties similar to brown dwarf stars and may

Which way does a mammoth skeleton point in Siberia? No, it’s not a Christmas cracker joke. To find the answer you have to look in a rather surprising place – the Institute of Physics’ new online archive.

In an article published in the first edition of Proceedings of the Physical Society in 1874, John Rae writes about the physical properties of ice and mammoth remains. He put forward a theory as to why so many of the mammoth skeletons found near the Yenesei river in Siberia had been found wi

The secret to its strength is a ring, Weizmann Institute researchers report in Science

Weizmann Institute scientists have found what makes the bacterium Deinococcus radiodurans the most radiation-resistant organism in the world: The microbe’s DNA is packed tightly into a ring. The findings, published in the January 10 issue of Science, solve a mystery that has long engaged the scientific community.

The red bacterium can withstand 1.5 million rads – a thousand times more tha

2% of buildings capable of having solar air-conditioning installed, could stop emitting 27,000 tons of CO2 into the atmosphere

The Basque Energy Authority (BEA) has been participating in the European ALTENER programme for the encouragement of renewable energies since their creation in 1992. Along these lines, the BEA has been chosen to develop a project involving the air-conditioning of buildings using renewable energies as an alternative to the traditional systems based on energies

In a milestone for global science collaboration, CERN took delivery today of the first US-built contribution to what will be the world’s highest-energy particle accelerator. The superconducting magnet, built at the US Brookhaven National Laboratory will become a key component of the Large Hadron Collider (LHC).

It is the first of several advanced accelerator elements the US will provide for the LHC under the terms of a 1998 agreement between CERN and the US Department of Energy (DOE)

Video cameras are used to keep an eye on many indoor and outdoor locations, but to pinpoint suspicious activity, human security guards or intelligence analysts have the unenviable task of watching dozens of video monitors or many hours of recorded video.

Supported by an NSF award, Jezekiel Ben-Arie and his students at the University of Illinois at Chicago have developed a technique, much faster and more reliable than previous methods, that allows a computer to recognize a human action contai

When 29-year-old Eric Lange suddenly experienced several hours of mental confusion last July, physicians at Cedars-Sinai Medical Center naturally ordered brain scans and carotid artery studies in their first search for a cause. With the initial exams turning out OK, Eric’s neurologist pursued other clues and ended up finding a heart defect called a patent foramen ovale, or PFO. A blood clot was believed to have slipped through the defect and out of the normal route of circulation that would

A Duke University Medical Center neurobiologist has identified key mechanisms by which the intricate “protein machines” that govern the strength of connections among neurons build and remodel themselves to adjust those connections.

Such remodeling of the connections, called synapses, is central to the establishment of brain pathways during learning and memory, said the scientists. Also, malfunction of the synaptic machinery might well play a fundamental role in the pathology of neurodegenera

Scientists study those vaccinated more than 60 years ago versus one year ago

Oregon Health & Science University researchers are studying the effectiveness of the smallpox vaccine in patients who received inoculations decades ago compared with those vaccinated more recently. The universal belief has been that smallpox vaccinations provide protection for only three to five years. Until now scientists and physicians assumed that anyone vaccinated more than five years ago had little to n

Can sentient machines evolve?

It’s coming, but when? From Garry Kasparov to Michael Crichton, both fact and fiction are converging on a showdown between man and machine. But what does a leading artificial intelligence expert–the world’s first computer science PhD–think about the future of machine intelligence? Will computers ever gain consciousness and take over the world?

“Computer sentience is possible,” said John Holland, professor of electrical engineering an

Brazil’s Pantanal, a vast wetland situated in the center of South America, has become the next frontier for leading-edge eco-tourists in search of ever more exotic flora and fauna. “It’s where people go after they’ve been to Africa,” says Shannon Bouton, a Ph.D. student in the School of Natural Resources and Environment (SNRE) at the University of Michigan.

This month, Bouton is publishing the results of her unique study of a wading bird colony in the Pantanal in the February

Forget sharp metal picks or X-rays-in the future, your dentist may search for cavities using a painless laser-based technique developed at U of T that can detect cracks or defects at an early stage of development. v “Using the technique, we can see all the way to the pulp-more than five millimetres inside a tooth,” says Professor Andreas Mandelis of U of T’s Department of Mechanical and Industrial Engineering. “It can reveal suspicious regions invisible to the naked eye below the surface of

Scientists with the U.S. Department of Energy’s Joint Genome Institute (JGI) and the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a powerful new technique for deciphering biological information encoded in the human genome. Called “phylogenetic shadowing,” this technique enables scientists to make meaningful comparisons between DNA sequences in the human genome and sequences in the genomes of apes, monkeys, and other non-human primates. With phylogenetic shadowing, scientists c

New research into the origin of kidney stone formation published in the March 1 issue of the Journal of Clinical Investigation may well change the direction of the most basic level of research in that area.

The study, conducted at Indiana University School of Medicine, Clarian Health Partners and the University of Chicago, will dispel the current beliefs of where stone formation begins, said Andrew P. Evan, Ph.D., the article’s lead author. Dr. Evan, who is a professor of anatomy and c

Fruits and veggies grown organically show significantly higher levels of cancer-fighting antioxidants than conventionally grown foods, according to a new study of corn, strawberries and marionberries. The research suggests that pesticides and herbicides actually thwart the production of phenolics — chemicals that act as a plant’s natural defense and also happen to be good for our health. Fertilizers, however, seem to boost the levels of anti-cancer compounds.

The findings appear in the

New work by researchers in the Kimmel Cancer Center at Johns Hopkins may allow them to halt the smoking-induced cellular events that lead to 99 percent of all small cell lung cancers (SCLC). The research is reported in the March 5, 2003, issue of Nature.

The researchers found that a primitive cellular pathway, called Sonic Hedgehog (named for the cartoon character and spiky hairs it develops on fruit flies) stays turned on long after it should be turned off in some lung cancers.
