3D Virtual Catalogue Transforms Access to Artworks Online

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

Slow-Evolving Species Gains Advantage in Mutual Relationships

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

Frozen Secrets of Mammoth Skeletons Discovered in Siberia

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

New Tech Identifies Human Activity in Video Feeds

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

Minimally Invasive Fix for Heart Defect Prevents Clots

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

Insights Into Nerve Connection Machinery and Synapse Remodeling

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

OHSU Study Compares Smallpox Vaccine Efficacy Over Decades

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

Organic Foods Pack More Cancer-Fighting Antioxidants

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 Target Discovered for Lung Cancer Therapy in Embryonic Pathway

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.
