54-million-year-old Skull Reveals Early Evolution Of Primate Brains Posted: 23 Jun 2009 08:00 AM PDT Researchers have developed the first detailed images of a primitive primate brain, unexpectedly revealing that cousins of our earliest ancestors relied on smell more than sight.

Curb A Cancer's Deadliness? Potent Metastasis Inhibitor Identified Posted: 23 Jun 2009 08:00 AM PDT Researchers have isolated a potent metastasis inhibitor produced by tumor cells, one that could potentially be harnessed as a cancer treatment. The protein, prosaposin, reduced metastases by 80 percent in a mouse model and significantly prolonged survival, the researchers report. Currently, there are no approved therapies for inhibiting or treating metastases.

How Aerosols Contribute To Climate Change Posted: 23 Jun 2009 08:00 AM PDT What happens in Vegas may stay in Vegas, but what happens on the way there is a different story. Scientists have analyzed the air blown by winds between San Diego and Las Vegas and now know what gives the road to Sin City a distinctive look.

Cancer Is Second Most Frequent Cause Of Death In Individuals With Schizophrenia Posted: 23 Jun 2009 08:00 AM PDT People with schizophrenia die from cancer four times as often as people in the general population. The study's results suggest that extra efforts should be made to improve cancer prevention and early detection in patients with schizophrenia.

Researchers Zero In On Ozone With Fluorescent Solution That Detects Harmful Molecule In The Air And Body Posted: 23 Jun 2009 08:00 AM PDT Researchers have developed a fluorescent substance that glows bright green when exposed to even minute amounts of ozone in the air and in biological samples such as human lung cells. A molecule consisting of three oxygen atoms, ozone is at once a harmful pollutant and lung irritant, and a possible natural weapon that certain research suggests the human body employs against infections.

United Kingdom's 'Taste Dialects' Defined For The First Time Posted: 23 Jun 2009 08:00 AM PDT Where we are born not only determines how we speak but also how we taste our food and drink.

Cold Case Techniques Bring Mummy’s Face To 'Life' Posted: 23 Jun 2009 05:00 AM PDT Thanks to the skills of artists who work on cold case investigations, people have a chance to see what the mummy Meresamun may have looked like in real life.

Transplant Drug Stimulates Immune Memory Posted: 23 Jun 2009 05:00 AM PDT Vaccination relies on cells that enable the immune system to respond faster and stronger upon second encounter with a pathogen. Rapamycin, a drug given to transplant patients to suppress their immune systems, unexpectedly stimulates cells responsible for immune memory in both mice and monkeys. The finding could lead to new ways to boost vaccine effectiveness and manipulate the different parts of the immune system.

Melatonin: The Fountain Of Youth? Posted: 23 Jun 2009 05:00 AM PDT Melatonin can slow down the effects of aging. Scientists have found that a treatment based on melatonin can delay the first signs of aging in a small mammal.

Newly Developed Antimicrobial Peptide May Protect Mice From Lethal Bacterial Infections Including MRSA Posted: 23 Jun 2009 05:00 AM PDT In a new study researchers suggest that a synthetic antimicrobial peptide identified as L5 may prevent death in mice suffering from life-threatening bacterial infections, such as MRSA, by activating the host immune response.

Alaskan Earthquake 'To Be Expected,' Says Researcher Posted: 23 Jun 2009 05:00 AM PDT As reports of a strong earthquake in Alaska continue to emerge (on June 22) a Baylor University earthquake researcher says this is not an unusual event in this area.

Physicians Frequently Fail To Inform Patients About Abnormal Test Results, Study Finds Posted: 23 Jun 2009 05:00 AM PDT New research shows that physicians failed to report clinically significant abnormal test results to patients -- or to document that they had informed them -- in one out of every 14 cases of abnormal results. In some medical groups, the failure rate is close to zero; in others it is as high as one in four abnormal results.

Bird Migration: Toxic Molecule May Help Birds 'See' North And South Posted: 23 Jun 2009 02:00 AM PDT A toxic molecule known to damage cells and cause disease may also play a pivotal role in bird migration. The molecule, superoxide, is proposed as a key player in the mysterious process that allows birds to "see" Earth's magnetic field.

Caucasians Are At Higher Risk Of Developing Ewing's Sarcoma Than Other Races Posted: 23 Jun 2009 02:00 AM PDT The largest analysis of its kind has found that Caucasians are much more likely that people in other racial/ethnic groups to develop a rare bone and soft tissue cancer called Ewing's sarcoma. In addition, among Caucasians with this cancer, men are more likely to die than women.
