Gulf of Mexico bottom still coated in oil, recovery long way off

and has 1 comment.
Samantha Joye of the University of Georgia has seen the bottom of the Gulf of Mexico and the view wasn't pretty. Speaking at the American Association for the Advancement of Science, Joye told the conference that she found places where oil lay on the Gulf floor nearly 4 inches (10 centimeters) thick. Joye's findings contradict rosier pictures of the overall damage caused by the 2010 BP oil spill, including a recent statement by Kenneth Feinberg, the US government czar for oil compensation, that the Gulf would largely recover by next year.

Baby dolphins dying along Gulf Coast

and has 1 comment.
Marine scientists are examining the deaths of 20 baby dolphins whose carcasses have washed ashore in Mississippi and Alabama this year, the bulk of them since last week, researchers said on Tuesday. The unusually large number of young dolphin deaths are being looked at as possible casualties of oil that fouled the Gulf of Mexico for months after a BP PLC drilling platform exploded in April 2010, killing 11 people and rupturing a wellhead on the sea floor. The bodies of 20 infant and stillborn dolphins have been discovered since January 20, most of them during the past week, on islands and beaches along a 130-mile stretch of coastline from Gulfport, Mississippi, east to Gulf Shores, Alabama.

Sheep Brains

and has no comments yet.
Despite having a comparable brain size to other highly evolved animals, sheep have been historically perceived as unintelligent and were therefore not considered to be good animal models for studying diseases that affect learning and memory. However, new research recently published in the journal PLoS ONE shows that sheep are indeed smarter than previously believed. The researchers are hopeful the animals will prove useful for research into diseases that impair the cognitive abilities of patients, such as Huntington's disease (HD) and Alzheimer's disease. Sheep are quadrupedal, ruminant mammals typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Although the name "sheep" applies to many species in the genus Ovis, in everyday usage it almost always refers to Ovis aries. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep.

Captive Gorillas Succumbing to Human Disease

and has 1 comment.
Life for humans is much easier than for animals in the wild. On a day-to-day basis, we generally do not have to worry about being eaten or starving to death. Depending on the individual's job, some can get by just fine by sitting around all day. However, this lifestyle brings forth its own set of health issues such as diabetes and heart disease, illnesses rarely found in the wild. These "human" diseases have spread to gorillas that are raised in captivity.

Bald Men and Prostate Cancer

and has 1 comment.
Men who start to lose hair at the age of 20 are more likely to develop prostate cancer in later life and might benefit from screening for the disease, according to a new study published online in the cancer journal, Annals of Oncology. The study set out to see if early-onset androgenic alopecia (which are directly connected to androgens such as testosterone) was associated with an increased risk of prostate cancer later in life. Androgens play a role in the development of both androgenic alopecia, commonly known as male pattern baldness, and prostate cancer. Testosterone, which is a very potent androgen or male hormone, is responsible for increased muscle mass, deepened voice and strong bones characteristic of the male gender. In addition, testosterone can contribute to aggression, libido, and growth of genitalia during puberty. Male hormones also have an effect on the liver and cholesterol; however, when it is converted into another androgen, it acts on the skin and hair follicles, and in some cases, producing male pattern baldness.

Climate change creates longer ragweed season

and has 1 comment.
A changing climate means allergy-causing ragweed pollen has a longer season that extends further north than it did just 16 years ago, U.S. scientists reported on Monday. In research that gibes with projections by the U.N. Intergovernmental Panel on Climate Change, plant and allergy experts found that ragweed pollen season lasted as much as 27 days longer in 2009 than it did in 1995. The further north in the Western Hemisphere, the more dramatic the change in the length of pollen season. Ragweed pollen can cause asthma flare-ups and hay fever, and costs about $21 billion a year in the United States, according to the study published in the Proceedings of the National Academy of Sciences.

Investing in greener economy could spur growth

and has 1 comment.
Channeling 2 percent, or $1.3 trillion, of global gross domestic product into greening sectors such as construction, energy and fishing could start a move toward a low-carbon world, a report launched on Monday said. The investment would expand the global economy at the same rate, if not higher, as under present economic policies, said the report by the U.N. Environment Program (UNEP). "Investing 2 per cent of global GDP into 10 key sectors can kick-start a transition toward a low-carbon world," the Nairobi-based agency said in a statement.
