Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers

03-28-2007 · EurekAlert!

A new, complete "tree of life" tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.

DNA gives new perspectives to understand the mysteries of nature
02-13-2007 · EurekAlert!
Scientific breakthrough: What caused the extinction of the woolly rhinoceros ten thousand years ago from an area in Europe covering the coasts of the Arctic Ocean in the north to the coasts of the Mediterranean in the south? What caused the extinction of the mammoth while other ice age mammals like the musk ox just barely survived to present day. A new scientific methodological approach to detect genetic material will help researchers to solve the many mysteries of the past.

The delayed rise of present-day mammals
03-28-2007 · EurekAlert!
It took 10 to 15 million years after the dinosaurs were wiped out before modern mammals -- including our ancient human ancestors -- were able to diversify and rise to their present-day prominence across the globe, a landmark new study has found.

A new target for the treatment of breast cancer
01-11-2007 · EurekAlert!
The active ingredient in a drug currently being tested to treat rheumatoid arthritis might also one day serve as an effective means of treating one of the deadliest forms of breast cancer. Berkeley Lab researchers have demonstrated that inhibiting the activity of the protease enzyme known as TACE can deprive tumor cells of a key factor needed for their proliferation. TACE is strongly present in a form of breast cancer which responds poorly to current therapies.

ASU researchers test antibacterial effects of healing clays
11-01-2006 · EurekAlert!
Clay is most commonly associated with the sublime experience of the European spa where visitors have been masked, soaked and basted with this touted curative since the Romans ruled. If Arizona State University geochemist Lynda Williams and microbiologist Shelley Haydel's research on the antibacterial properties of clays realizes its full potential, smectite clay could one day rise above cosmetic use to take its place comfortably with antibacterial behemoths like penicillin.

Mobile phones can soon survive being dropped
03-25-2007 · EurekAlert!
Dutch researcher Paulette Prins has demonstrated that plastic does not have to be a poorer conductor than present-day semi-conductors. This opens up the way for a revolution in consumer electronics: Mobile phones and MP3 players will soon survive being dropped.

UD researchers race ahead with latest spintronics achievement
10-26-2007 · EurekAlert!
In a rapid follow-up to their achievement as the first to demonstrate how an electron's spin can be electrically injected, controlled and detected in silicon, electrical engineers from the University of Delaware and Cambridge NanoTech now show that this quantum property can be transported a marathon distance in the world of microelectronics -- through an entire silicon wafer. The finding confirms that silicon -- the workhorse material of present-day electronics -- now can be harnessed up for new-age spintronics applications.

Rutgers scientists discover brain cell development process implicated in mental retardation
07-31-2007 · EurekAlert!
Scientists at Rutgers University have discovered a biological process in brain cell development that may help explain some causes of mental retardation. This understanding may one day help other researchers develop therapies that can reduce specific forms of retardation. Proteins of the Rho family, when excessively present in developing brain cells known as neurons, inhibit another protein, called cypin, that promotes healthy neuron development.

Testing delays cause severe AIDS complications, Einstein researchers find
11-02-2007 · EurekAlert!
Despite the availability of life-saving antiretroviral treatment, people infected with HIV continue to die and suffer from complications of AIDS, mainly due to delayed diagnosis and initiation of treatment. A researcher at the Albert Einstein College of Medicine of Yeshiva University and colleagues at Yale University have shed light on why this problem persists. They report their findings in the November issue of the journal Medical Care.

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex
04-12-2007 · EurekAlert!
In a venture once thought to lie outside the reach of science, researchers from Harvard Medical School and Beth Israel Deaconess Medical Center have captured and sequenced tiny pieces of collagen protein from a 68 million-year-old Tyrannosaurus rex. The protein fragments -- seven in all -- appear to most closely match amino acid sequences found in collagen of present day chickens, lending support to a recent and still controversial proposal that birds and dinosaurs are evolutionarily related.

No need to thank dinosaur-killing asteroid for mammalian success
03-28-2007 · EurekAlert!
A new study published in the March 29 issue of the journal Nature challenges the prominent hypothesis that a mass extinction of dinosaurs 65 million years ago played a major role in the diversification of today’s mammals.
