Between 1880 and 2006 the average global annual temperature was about 15°C. However, in the years after 1990 the frequency of years when this average value was exceeded increased. http://www.physorg.com/news150718583.html Space & Earth Fri, 09 Jan 2009 10:16:23 EST news150718583 New research indicates that the ocean could rise in the next 100 years to a meter higher than the current sea level - which is three times higher than predictions from the UN's Intergovernmental Panel on Climate Change, IPCC. The groundbreaking new results from an international collaboration between researchers from the Niels Bohr Institute at the University of Copenhagen, England and Finland are published in the scientific journal Climate Dynamics. http://www.physorg.com/news150645386.html Space & Earth Thu, 08 Jan 2009 13:56:26 EST news150645386 (PhysOrg.com) -- The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling. http://www.physorg.com/news150642726.html Biology Thu, 08 Jan 2009 13:12:06 EST news150642726 The combination of estrogen plus progestin, which women stopped taking in droves following the news that it may increase their risk of breast cancer, may decrease their risk of colorectal cancer, according to a report published in the January issue of Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research. http://www.physorg.com/news150616082.html Medicine & Health Thu, 08 Jan 2009 05:48:02 EST news150616082 (PhysOrg.com) -- Winter quarter at UC San Diego begins on Jan. 5 and many students are carrying a variety of New Year`s resolutions along with their textbooks.

Then forest fires broke out across the continent, sending up a thick layer of soot and dust that blocked out the sun. A sudden ice age ensued, and some of the Earth's largest animals went extinct in a blink of geological time. http://www.physorg.com/news150097682.html Space & Earth Fri, 02 Jan 2009 05:48:02 EST news150097682 (PhysOrg.com) -- Extremes are exciting. Does anyone really think dinosaurs would capture our imagination the way they do if they hadn't been so huge? You don't see natural history museums vying for fossil skeletons of prehistoric rodents. It's the Tyrannosaurus rex fossils they salivate and squabble over. And would the Hollywood glitterati cart around those little teacup pups if they weren't so dang tiny and cute? Not likely. http://www.physorg.com/news149188848.html Space & Earth Mon, 22 Dec 2008 17:20:48 EST news149188848 Italy's mountains, from the Apennines to the Alps, have fascinated University of California, Berkeley, geologist Walter Alvarez for more than 35 years, resulting in a new book, "The Mountains of Saint Francis," that traces Italy's billion-year geologic history with a focus on Italian geologists and their groundbreaking - and often overlooked - discoveries. http://www.physorg.com/news149170904.html Space & Earth Mon, 22 Dec 2008 12:21:44 EST news149170904 (PhysOrg.com) -- The Martian arctic soil that NASA's Phoenix Mars Lander dug into this year is very cold and very dry. However, when long-term climate cycles make the site warmer, the soil may get moist enough to modify the chemistry, producing effects that persist through the colder times. http://www.physorg.com/news148581442.html Space & Earth Mon, 15 Dec 2008 16:37:22 EST news148581442 A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine is the first to show the full clinical picture of comorbid conditions associated with obstructive sleep apnea (OSA), quantify their frequency of occurrence and reveal their possible interrelationships. http://www.physorg.com/news148543512.html Medicine & Health Mon, 15 Dec 2008 06:05:12 EST news148543512 (PhysOrg.com) -- Half of the globe has warmed at least one half of one degree Fahrenheit (0.3 C) in the past 30 years, while half of that -- a full quarter of the globe -- warmed at least one full degree Fahrenheit (0.6 C), according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville. http://www.physorg.com/news148239677.html Space & Earth Thu, 11 Dec 2008 17:41:17 EST news148239677 (PhysOrg.com) -- University of Queensland research has found one of Australia's iconic animals is not a shadow of its former self. http://www.physorg.com/news148230075.html Biology Thu, 11 Dec 2008 15:01:15 EST news148230075 (PhysOrg.com) -- Researchers have discovered that the ocean's chemical makeup is less stable and more greatly affected by climate change than previously believed. The researchers report in the December 12, 2008 issue of Science that during a time of climate change 13 million years ago the chemical makeup of the oceans changed dramatically. The researchers warn that the chemical composition of the ocean today could be similarly affected by climate changes now underway - with potentially far-reaching consequences for marine ecosystems. http://www.physorg.com/news148227653.html Space & Earth Thu, 11 Dec 2008 14:20:53 EST news148227653 Found in the nearby Large Magellanic Cloud, 30 Doradus is one of the largest massive star forming regions close to the Milky Way. Enormous stars in 30 Doradus, also known as the Tarantula Nebula, are producing intense radiation and searing winds of multimillion-degree gas that carve out gigantic bubbles in the surrounding cooler gas and dust. http://www.physorg.com/news148224290.html Space & Earth Thu, 11 Dec 2008 13:24:50 EST news148224290 More than half of younger mantle cell lymphoma patients who received an intensive regimen of chemotherapy as frontline treatment remain in remission seven years later, researchers at The University of Texas M.

Because Earth has lost almost all geological records of this era from its surface, it`s often considered the planet`s dark ages. http://www.physorg.com/news147960214.html Space & Earth Mon, 08 Dec 2008 12:03:34 EST news147960214 A new Mayo Clinic study found that patients with low-grade gliomas survived longest when they underwent aggressive surgeries to successfully remove the entire tumor. If safely removing the entire tumor was not possible, patients survived significantly longer when surgery was followed by radiation therapy. This study is available online as an advance publication in Neuro-Oncology. http://www.physorg.com/news147546162.html Medicine & Health Wed, 03 Dec 2008 17:02:42 EST news147546162 Older people tend to feel about 13 years younger than their chronological age. That is one of the findings of a study forthcoming in the Journals of Gerontology: Psychological Science. The researchers analyzed the responses of 516 men and women age 70 and older who participated in the Berlin Aging Study, tracking how their perceptions about age and their satisfaction with aging changed over a six-year period. http://www.physorg.com/news147452737.html Medicine & Health Tue, 02 Dec 2008 15:05:37 EST news147452737 The genome of a squirrel-sized, saucer-eyed lemur from Madagascar may help scientists understand how HIV-like viruses coevolved with primates, according to new research from the Stanford University School of Medicine.

Scientists at the Carnegie Institution have found that the mineral kingdom co-evolved with life, and that up to two thirds of the more than 4,000 known types of minerals on Earth can be directly or indirectly linked to biological activity. The finding, published in American Mineralogist, could aid scientists in the search for life on other planets. http://www.physorg.com/news145805221.html Space & Earth Thu, 13 Nov 2008 13:27:01 EST news145805221 All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these reactions proceed spontaneously, in the absence of enzymes - minutes, hours, days?
