Coolest Spacecraft Ever In Orbit (-273 Degrees Celsius) Posted: 04 Jul 2009 02:00 PM PDT On July 2 the detectors of Planck's High Frequency Instrument reached their amazingly low operational temperature of -273°C, making them the coldest known objects in space. The spacecraft has also just entered its final orbit around the second Lagrange point of the Sun-Earth system, L2.

'Jumping Gene' Diminishes The Effect Of New Type 2 Diabetes Risk Gene Posted: 04 Jul 2009 02:00 PM PDT Research has identified a new gene associated with diabetes, together with a mechanism that makes obese mice less susceptible to diabetes. A genomic fragment that occurs naturally in some mouse strains diminishes the activity of the risk gene Zfp69. The researchers also found that the corresponding human gene (ZNF642) is especially active in overweight individuals with diabetes.

New Treatment For Receding Gums: No Pain, Lots Of Gain Posted: 04 Jul 2009 02:00 AM PDT Dental researchers have demonstrated three-year success with a tissue regeneration application that reduces the pain and recovery time of gum grafting surgery. This specific treatment eliminates the need to take tissue from the roof of the mouth.

HIV-related Death: Predicting Fatal Fungal Infections Posted: 04 Jul 2009 02:00 AM PDT Researchers have identified cells in blood that predict which HIV-positive individuals are most likely to develop deadly fungal meningitis, a major cause of HIV-related death. This form of meningitis affects more than 900,000 HIV-infected people globally--most of them in sub-Saharan Africa and other areas of the world where antiretroviral therapy for HIV is not available.

Immunology: Interleukin-21 Keeps Defense Cells In Good Trim Posted: 04 Jul 2009 02:00 AM PDT Interleukin-21 plays a crucial role in fighting off chronic viral infections, scientists recently concluded. The discovery offers hope for specific treatments against HIV, hepatitis C and B, and tumors.

Shape Matters In The Case Of Cobalt Nanoparticles Posted: 04 Jul 2009 02:00 AM PDT New studies show that changing the shape of cobalt nanoparticles from spherical to cubic can fundamentally change their behavior.

Children With Autism Need To Be Taught In Smaller Groups, Experts Argue Posted: 04 Jul 2009 02:00 AM PDT Since the 1970s, there has been much debate surrounding the fact that individuals with autism have difficulty in understanding speech in situations where there is background speech or noise. Neuroscientists argue in favor of smaller class sizes for children with autism.

Triggering Muscle Development: A Therapeutic Cure For Muscle Wastage? Posted: 03 Jul 2009 08:00 PM PDT Scientists have shown that if elderly men who were given growth hormone and exercised their legs showed an appreciable muscle mass increase. Researchers say, "This raises the question: Can age-related loss of muscle strength and increased fragility be ameliorated by the therapeutic application of mechano growth factor?"

Police Work Undermines Cardiovascular Health, Comparison To General Population Shows Posted: 03 Jul 2009 08:00 PM PDT It is well documented that police officers have a higher risk of developing heart disease: The question is why. In the most recent results coming out of one of the few long-term studies being conducted within this tightly knit society, researchers have determined that underlying the higher incidence of subclinical atherosclerosis -- arterial thickening that precedes a heart attack or stroke -- may be the stress of police work.

Risk Of Liver Cancer In Women With Hepatitis B Virus Infection Varies With Number Of Pregnancies Posted: 03 Jul 2009 08:00 PM PDT Risk for hepatocellular carcinoma, a primary malignancy of the liver, was statistically significantly higher among women with hepatitis B virus (HBV) infection than among women without the virus, according to a new study.

Methane-producing Molecule Can Also Repair DNA Posted: 03 Jul 2009 08:00 PM PDT The Archaea are single-celled organisms and a domain unto themselves, quite apart from the so called eukaryotes (bacteria and higher organisms). Many species live under extreme conditions, and carry out unique biochemical processes shared neither with bacteria nor with eukaryotes. Methanogenic archaeans, for example, can produce methane gas out of carbon dioxide and hydrogen.

Overweight Kids Experience More Loneliness, Anxiety Posted: 03 Jul 2009 08:00 PM PDT As childhood obesity rates continue to increase, experts agree that more information is needed about the implications of being overweight as a step toward reversing current trends.
