A study at Ohio State University has uncovered more evidence that black holes form before the galaxies that contain them.

The finding could help resolve a long-standing debate, said Marianne Vestergaard, a postdoctoral fellow in astronomy at Ohio State.

Vestergaard came to this conclusion when she studied a collection of very energetic, active galaxies known as quasars as they appeared some 12 billion years ago, when the universe was only one billion years old. While the quasars wer

Finnish Miotec has increased smartcard security through biometrics, which uses physical characteristics, such as fingerprint, retinal patterns, or voice to identify an individual.

Biometric technology uses physical characteristics, such as fingerprint, retinal patterns, or voice to identify an individual. In traditional biometric technology, the biometric information was stored in databases or readers. Not only was this exposing the secure information to hacking, but was considered a violati

Studies indicate that the number of diagnosed cases of Autism, or autistic spectrum disorder, is increasing with around 0.6% of the population affected. Early infantile autism was first described almost 60 years ago and autism has been the subject of intense research activities ever since, however the origin of the condition is still not understood. This review issue of Philosophical Transactions B, a Royal Society publication, provides a comprehensive overview of the latest research on autism and hi

US fertility experts have discovered a potential new role for the wonder drug tamoxifen – helping breast cancer patients to have babies by IVF.

In a study published today (Wednesday 8 January) in Europe’s leading reproductive medicine journal Human Reproduction [1], researchers from New York’s Cornell University report the first IVF pregnancy to result from the use of tamoxifen as an ovarian stimulant.

In a study of 12 breast cancer survivors they found that stimulating the ovaries

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

Unless the pace of global warming is abated, polar bears could disappear within 100 years, says a University of Alberta expert in Arctic ecosystems.

While it has been known for some time that the polar bear is in trouble, new research shows that Arctic ice–the polar bear’s primary habitat–is melting much faster than scientists had believed, says U of A biologist Dr. Andrew Derocher.

“The climate predictions coming out are showing massive changes in sea-ice distribution,” sa
