Since May 2009, the tropical Pacific Ocean has switched from a cool pattern of ocean circulation known as La Niña to her warmer sibling, El Niño. This cyclical warming of the ocean waters in the central and eastern tropical Pacific generally occurs every three to seven years, and is linked with changes in the strength of the trade winds. El Niño can affect weather worldwide, including the Atlantic hurricane season, Asian monsoon season and northern hemisphere winter storm season. But while scientists agree that El Niño is back, there's less consensus about its future strength.

Woody Plants Adapted To Past Climate Change More Slowly Than Herbs
http://feeds.sciencedaily.com/~r/sciencedaily/~3/bcNs60hDyAs/090923121441.htm
Can we predict which species will be most vulnerable to climate change by studying how they responded in the past? A new study of flowering plants provides a clue. An analysis of more than 5,000 species reveals that woody plants adapted to past climate change more slowly than herbaceous plants did. If the past is any indicator of the future, woody plants may have a harder time than other plants keeping pace with global warming.

Regulating The Regulators: New Therapeutic Approach Against Cancer
http://feeds.sciencedaily.com/~r/sciencedaily/~3/bR25IzV56zU/090916092542.htm
The development of cancer involves the uncontrolled growth of normal cells of the body. Our immune system can sense the growth of the tumor cells and can usually eliminate them using direct killing mechanisms, mediated by natural killer cells and cytotoxic T lymphocytes. However, the tumor has an arsenal of strategies to counteract the immune response that seeks to eliminate it. Researchers have developed a new strategy to selectively block the tumor induced immunosuppression and thereby enhance the efficacy of tumor immunotherapeutics.

When You've Doubled Your Genes, What's One Chromosome More Or Less? How Polyploidy And Genomic Change Can Lead To Evolutionary Change
http://feeds.sciencedaily.com/~r/sciencedaily/~3/qIjPnM0THww/090914172646.htm
For animals, an extra chromosome can result in major problems, but plants are another matter. Many plants can survive an extra copy of their entire genome (polyploidy), and this process often results in a new species, making it an important mechanism in evolution. In fact, over 80 percent of plants may be a product of polyploidy. This research examines how polyploidy and genomic change can lead to evolutionary change, and affect plants' fitness and vigor.

Blood Vessels Contribute To Their Own Growth And Oxygen Delivery To Tissues And Tumors
http://feeds.sciencedaily.com/~r/sciencedaily/~3/QE9Dw_3PTCQ/090914173014.htm
Researchers have identified a new biological process that spurs the growth of new blood vessels. Vascular networks form and expand by “sprouting,” similar to the way trees grow new branches. The process allows fresh oxygen and nutrients to be delivered to tissues, whether in a developing embryo or a cancerous tumor. Up until now, scientists thought that the molecular signals to form new sprouts came from outside the vessel. But new research has shown that signals can also come from within the blood vessel, pushing new blood vessel sprouts outward.

New Method Monitors Early Sign Of Oxidative Stress In Cancer

The growth of cancerous tumors is fueled, at least in part, by the buildup of free radicals--highly reactive oxygen-containing molecules. It stands to reason, then, that cancer should respond to treatment with antioxidants, which inhibit the rogue radicals, or with pro-oxidants, which go the opposite direction, increasing "oxidative stress" on cancer cells to the point of vanquishing them. But experiments with such treatments have had mixed results, possibly because patients differ in their "redox profiles," or oxidative stress levels.

Some Mysteries Of Neonatal Seizures Explained
http://feeds.sciencedaily.com/~r/sciencedaily/~3/w_ziWhKOE_8/090909122058.htm
A new study provides new insight into the mechanism of neonatal seizures, which have features very different from seizures in older children and adults. The finding that neurons in different parts of the brains of newborn mammals respond differently to the neurotransmitter GABA may explain why seizures in the neonatal brain may not produce visible convulsions and why the antiseizure drug phenobarbital can exacerbate the invisible nature of neonatal seizures.

For Peat's Sake: Alternative Growing Media
http://feeds.sciencedaily.com/~r/sciencedaily/~3/CRB-nVmc9as/090904165253.htm
Peat, or semi-decayed vegetation matter, has been used by commercial growers and amateur gardeners since the middle of the 20th century. Peat is added to potting soil to help retain moisture and provide additional nutrients. Concerns about the environmental impact of extracting peat from wetlands are mounting. Researchers evaluated five materials as partial peat substitutes. The results show these alternatives have potential.

Why Solitary Reptiles Lay Eggs In Communal Nests
http://feeds.sciencedaily.com/~r/sciencedaily/~3/Xn2dtJFuGSI/090903093149.htm
Reptiles are not known to be the most social of creatures. But when it comes to laying eggs, female reptiles can be remarkably communal, often laying their eggs in the nests of other females. New research suggests that this curiously out-of-character behavior is far more common in reptiles than was previously thought.

Astronomers have taken a striking new image of a nearby galaxy that many astronomers think closely resembles our own Milky Way. Though the galaxy is seen edge-on, observations of NGC 4945 suggest that this hive of stars is a spiral galaxy much like our own, with swirling, luminous arms and a bar-shaped central region. These resemblances aside, NGC 4945 has a brighter center that likely harbors a supermassive black hole, which is devouring reams of matter and blasting energy out into space.
