Tarantula Nebula glows with X-rays and infrared light Posted: 13 Nov 2011 08:21 PM PST The star-forming region 30 Doradus is one of the largest located close to the Milky Way and is found in the neighboring galaxy Large Magellanic Cloud. About 2,400 massive stars in the center of 30 Doradus, also known as the Tarantula Nebula, are producing intense radiation and powerful winds as they blow off material.

Prenatal exposure to environmental pollutants may affect weight and size of newborn Posted: 13 Nov 2011 11:27 AM PST A higher exposure to xenoestrogens -- a type of environmental pollutants acting as hormones -- might affect neonatal weight and size in term infants. Researchers have found a correlation between estrogenic burden in women's placenta and a higher neonatal weight at birth.

Climate policies can help resolve energy security and air pollution challenges Posted: 13 Nov 2011 11:27 AM PST Policies to protect the global climate and limit global temperature rise offer the most effective entry point for achieving energy sustainability, reducing air pollution, and improving energy security, according to a new article. By adopting an integrated perspective on energy and climate policy, one that simultaneously addresses three of the key objectives for energy sustainability, major synergies and cost co-benefits can be realized.

Tamoxifen resistance -- and how to defeat it Posted: 13 Nov 2011 11:14 AM PST In the last three decades, thousands of women with breast cancer have taken the drug tamoxifen, only to discover that the therapy doesn't work, either because their tumors do not respond to the treatment at all, or because they develop resistance to it over time. Now researchers have discovered the molecular basis for tamoxifen resistance and found a potential way to defeat it.

New way to target – and kill – proliferating tumors Posted: 13 Nov 2011 11:14 AM PST Researchers have identified a new drug discovery approach enabling the destruction of the most highly proliferative tumors. The discovery points to an effective, alternative method for killing fast-growing cancer cells without causing some of the negative effects of current therapies.

More flexible window into the brain Posted: 13 Nov 2011 11:14 AM PST Scientists have developed and tested a new high-resolution, ultra-thin device capable of recording brain activity from the cortical surface without having to use penetrating electrodes. The device could make possible a whole new generation of brain-computer interfaces for treating neurological and psychiatric illness and research.

Signaling pathway linked to inflammatory breast cancer may drive disease metastasis Posted: 13 Nov 2011 11:14 AM PST Amplification of anaplastic lymphoma kinase, which has been reported in other cancers such as non-small cell lung cancers, may be a primary driver of the rapid metastasis that patients with inflammatory breast cancer experience.

Benefit of novel drug in breast cancer seen in blood within weeks Posted: 13 Nov 2011 11:14 AM PST Clinical benefit from use of a novel histone deacetylase inhibitor drug may be determined by examining blood cells days after a patient receives treatment. The drug, entinostat, is the first histone deacetylase inhibitor successfully tested in a randomized, placebo-controlled study in metastatic breast cancer — and is the first to show that clinical outcome can be predicted shortly after administration.

Rising air pollution worsens drought, flooding, new study finds Posted: 13 Nov 2011 11:13 AM PST Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall and the intensity of severe storms in wet regions or seasons, says a new study. The research provides the first clear evidence of how aerosols can affect weather and climate, with important economic and water resource implications.

Wearable defibrillator can prevent death in people with arrhythmias, research finds Posted: 13 Nov 2011 11:13 AM PST A wearable defibrillator can prevent sudden death in people with dangerous heart arrhythmias, according to new research.

Intensive diabetes therapy protects Type 1 diabetics' kidneys Posted: 12 Nov 2011 11:53 AM PST Scientists looked to see if intensive diabetes therapy aimed at reducing blood sugar as close to the normal range as possible might protect Type 1 diabetics' kidney function.

Violent passions: Jealous cleaner shrimp murder their rivals Posted: 11 Nov 2011 06:55 AM PST The hermaphroditic cleaner shrimp Lysmata amboinensis usually live in monogamous pairs, but dark passions underlie their social structure. New research shows that cleaner shrimp, in any group larger than two, viciously attack and kill each other until only a single pair remains.
