It may be used in combination with currently available methods to produce more complex mouse models to understand disease.

Millionths Of A Second Can Cost Millions Of Dollars: A New Way To Track Network Delays Posted: 31 Aug 2009 11:00 AM PDT Computer scientists have developed an inexpensive solution for diagnosing networking delays in data center networks as short as tens of millionths of seconds -- delays that can lead to multi-million dollar losses for investment banks running automatic stock trading systems.

The Science Of Longer Lasting Lager Posted: 31 Aug 2009 11:00 AM PDT One of the long standing problems in the drinks industry is how to prevent chemical processes in the drinks compromising their taste, quality and shelf life. In particular, riboflavin (vitamin B2) is responsible for driving photooxidation reactions that affect the flavour of many drinks and so they often have to be packaged in light-shielded containers. Now scientists have developed a way of removing riboflavin.

World's Smallest Semiconductor Laser Heralds New Era In Optical Science Posted: 31 Aug 2009 08:00 AM PDT Researchers have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.

Light Shed On Cause Of Down Syndrome And Other Genetic Disorders Posted: 31 Aug 2009 08:00 AM PDT Scientists have a better understanding of what causes an abnormal number of chromosomes in offspring, a condition called aneuploidy that encompasses the most common genetic disorders in humans, such as Down syndrome, and is a leading cause of pregnancy loss.

New Analysis Details Devastating Toll Of Neglected Tropical Diseases In Sub-Saharan Africa Posted: 31 Aug 2009 08:00 AM PDT New light has been shed on the toll that neglected tropical diseases take on sub-Saharan Africa, with an estimated 500 million people suffering from these debilitating and sometimes deadly diseases. Helminth infections account for approximately 85 percent of the NTD burden. Overall, the NTD burden may be equivalent to more than double that caused by tuberculosis and up to one-half of SSA's malaria disease burden.

International Greenland Ice Coring Effort Sets New Drilling Record In 2009 Posted: 31 Aug 2009 08:00 AM PDT A new international research effort on the Greenland ice sheet has set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future.

Disease Threat May Change How Frogs Mate Posted: 31 Aug 2009 08:00 AM PDT A disease may be causing a behavioral change in frogs. The research has unearthed a surprising fact about our long-tongued friends: wild frogs in the UK may be changing their mating behavior.

Neuroscientists Find Brain Region Responsible For Our Sense Of Personal Space Posted: 31 Aug 2009 05:00 AM PDT In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists have pinpointed the brain structure responsible for our sense of personal space. The discovery could offer insight into autism and other disorders where social distance is an issue.

Protein Involved In Causing Gum Disease, Osteoporosis, Arthritis Identified Posted: 31 Aug 2009 05:00 AM PDT Investigators have discovered that a gene called interferon regulator factor-8 is involved in the development of diseases such as periodontitis, rheumatoid arthritis and osteoporosis. The study could lead to new treatments in the future.

Tiny 'MEMS' Devices To Filter, Amplify Electronic Signals Posted: 31 Aug 2009 05:00 AM PDT Researchers are developing a new class of tiny mechanical devices containing vibrating, hair-thin structures that could be used to filter electronic signals in cell phones and for other more exotic applications.

Human Breast Cancer Hit For Six: Key Role For Six1 In Tumor Development And Metastasis Posted: 31 Aug 2009 05:00 AM PDT Researchers have provided new insight into breast cancer development using mouse models and analysis of human cells, implicating the protein Six1 as central to this process.

Safer, Denser Acetylene Storage In An Organic Framework Posted: 31 Aug 2009 05:00 AM PDT The century-old challenge of storing and transporting acetylene safely may have been solved in principle by a team of scientists.

Dentists Urged To Take A Role In Identifying Children Suffering From Neglect Posted: 31 Aug 2009 05:00 AM PDT A new policy urging dentists to check for tell-tale signs of neglect when treating children with severe oral disease has been published.

New Prognostic Marker For Human Breast Cancer Posted: 31 Aug 2009 02:00 AM PDT Elevated levels of GLI1 (glioma-associated oncogene homolog 1) protein in human breast cancer are associated with unfavorable prognosis and progressive stages of disease. Researchers found increased expression of GLI1 in samples taken from more advanced and less survivable tumors.

Analysis Of Copernicus Putative Remains Support Identity Posted: 31 Aug 2009 02:00 AM PDT Researchers have published results from the analysis of the putative remains of Copernicus. A DNA-analysis of shed hairs found in a book from Museum Gustavianum, Uppsala University, was one interesting piece in the project.

Collagen-deficient Mice Show Signs Of Osteoarthritis Posted: 31 Aug 2009 02:00 AM PDT Researchers conducted a study of mice to determine the effect of Type IX collagen (Col9a1) deficiency on functional ability. The authors found that mice with the Col9a1 gene inactivated prematurely develop OA and DDD.

Mysterious Charge Transport In Self-assembled Monolayer Transistors Unraveled Posted: 31 Aug 2009 02:00 AM PDT Researchers have discovered that monolayer coverage and channel length set the mobility in self-assembled monolayer field-effect transistors (SAMFETs). This opens the door to extremely sensitive chemical sensors that can be produced in a cost-effective way.

Palliative Care Intervention For Patients With Advanced Cancer Provides Quality Of Life Benefits Posted: 31 Aug 2009 02:00 AM PDT Patients with advanced cancer who received a palliative care intervention focused on addressing physical and psychosocial issues and care coordination that was provided at the same time as cancer treatment reported improved quality of life and mood but did not experience a significant change in the number of days in the hospital or the severity of their symptoms compared to patients who received usual care, according to a new study.

Virus Enzymes Could Promote Human, Animal Health Posted: 30 Aug 2009 11:00 PM PDT Could viruses be good for you? Scientists with the Agricultural Research Service (ARS) have shown that enzymes from bacteria-infecting viruses known as phages could have beneficial applications for human and animal health.

Unique Study Isolates DNA From Linnaeus' Botanical Collections Posted: 30 Aug 2009 11:00 PM PDT Researchers have succeeded in extracting long DNA fragments from dried, pressed plant material collected in the 1700s by Linnaeus' apprentice Adam Afzelius. It is hoped that the study will shed light on whether plants growing today at Linnaeus' Hammarby estate outside Uppsala reflect the species cultivated by Linnaeus himself.

New Study Suggests An Unidentified Source As Cause Of Residual Viremia In HIV-1 Patients On HAART Posted: 30 Aug 2009 11:00 PM PDT A new study suggests that an unidentified cellular source may be responsible for residual viremia in HIV-1 patients on highly active antiretroviral therapy (HAART). This discovery disputes previous theories that attributed residual viremia to latent proviruses in resting CD4+ T cells and could significantly impact eradication efforts.

Coralline Algae In The Mediterranean Lost Their Tropical Element Between 5 And 7 Million Years Ago Posted: 30 Aug 2009 11:00 PM PDT Scientists have studied the coralline algae fossils that lived on the last coral reefs of the Mediterranean Sea between 7.24 and 5.3 million years ago. Mediterranean algae and coral reefs began to resemble present day reefs following the isolation of the Mediterranean from the Indian Ocean and global cooling 15 and 20 million years ago respectively.

Psychosocial Therapy With Antidepressants More Effective In Helping Depressed Stroke Patients Posted: 30 Aug 2009 11:00 PM PDT Depressed stroke patients who received medication and psychosocial therapy improved significantly in the short term and a year later, compared to those receiving medication alone. The psychosocial therapy focused on depression education, problem-solving and increasing pleasant experiences. Depression is common after stroke and can impede recovery.
