Antarctic thaw quickens, trillions of tonnes of ice raise sea levels

Antarctic thaw quickens, trillions of tonnes of ice raise sea levelsBy Alister Doyle Environment Correspondent OSLO (Reuters) – An accelerating thaw of Antarctica has pushed up world sea levels by almost a centimeter since the early 1990s in a risk for coasts from Pacific islands to Florida, an international team of scientists said on Thursday. Antarctica has enough ice to raise seas by 58 meters (190 ft) if it ever all melted, dwarfing frozen stores in places from Greenland to the Himalayas and making its future the biggest uncertainty in understanding global warming and ocean levels. The frozen continent lost almost three trillion tonnes of ice between 1992 and 2017, the 84 scientists said in what they called the most complete overview of Antarctic ice to date.

Carbon dioxide levels grew at record pace in 2016, U.N. says

Carbon dioxide levels grew at record pace in 2016, U.N. saysBy Tom Miles GENEVA (Reuters) – The amount of carbon dioxide in the earth’s atmosphere grew at record rate in 2016 to a level not seen for millions of years, potentially fuelling a 20-metre rise in sea levels and adding 3 degrees to temperatures, the United Nations said on Monday. Atmospheric concentrations of carbon dioxide (CO2), the main man-made greenhouse gas, hit 403.3 parts per million (ppm), up from 400.0 in 2015, the U.N. World Meteorological Organization said in its annual Greenhouse Gas Bulletin.

Racism levels in US communities predict how many black people police will kill there, study shows

Racism levels in US communities predict how many black people police will kill there, study showsThe racial biases of white members of a community have a direct link to the number of black people shot and killed by police officers in that same area, new research indicates. A study published last year found that African Americans are almost three times more likely than white people to be killed by the police’s use of force. “We expected many economic or demographic variables such as the overall wealth of an area, residential segregation, average levels of education in the area, or overall crime levels, to be involved,” said the report’s lead author, Eric Hehman.

Antarctic meltwater lakes threaten sea levels: study

Antarctic meltwater lakes threaten sea levels: studyAntarctic meltwater lakes are far more common than once thought and could destabilise glaciers, potentially lifting sea levels by metres as global warming sets in, scientists said Wednesday. Most vulnerable are the massive, floating ice shelves that ring the Antarctic continent and help prevent inland glaciers from sliding toward the sea, they reported in the journal Nature. Antarctica holds enough frozen water to push up global oceans by tens of metres.

Shingles vaccination not at goal levels for U.S. seniors

By Madeline Kennedy (Reuters Health) – Just one in five people over age 60 in the U.S. have been vaccinated against a painful eruption of herpes zoster, also known as shingles, despite recommendations that all of them should get the shot. Shingles is caused by the same virus as chicken pox, which remains dormant in the body and can reactivate in times of stress or when the immune system is weakened. After age 80, half of adults have had shingles.

Stopping birth control could cause a drop in vitamin D levels, suggests new research

Stopping birth control could cause a drop in vitamin D levels, suggests new researchWomen who stop taking the pill could experience a drop in vitamin D levels, according to a new US study which looked at levels of the vitamin in African-American women. Published on Thursday, August 4 in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism, the study found that levels of vitamin D fell when women stopped using birth control pills or other contraceptives containing estrogen, which could be of particular importantance to those who stop their birth control in order to become pregnant. The researchers looked at a total of 1662 African-American women aged 23-34 years, all living in the Detroit area in Michigan, USA.

Caffeine linked with lower levels of erectile dysfunction

A few cups of coffee a day is associated with a lower incidence of ED, a new study shows.Men who drank two to three cups of coffee a day, or their equivalent in caffeine, were found to be less likely to have erectile dysfunction (ED) in a study from the University of Texas Health Science Center at Houston. In the study, which was published in PLOS ONE, men who consumed 85-170 milligrams of caffeine a day were 42 percent less likely to report ED, while those who drank 171-303 mg daily were 39 percent less likely compared to those who drank 0-7 mg a day. Caffeine sources included coffee, tea, soda and sports drinks.

Designer molecule lowers HIV levels: trial results

Designer molecule lowers HIV levels: trial resultsResearchers said Wednesday a lab-manufactured antibody "significantly" reduced HIV blood levels in a small but promising human trial, and caused no harmful side effects. This meant the designer molecule dubbed 3BNC117 may be best used in combination with other drugs, said the team — while highlighting the promise of a new, immunotherapy-based approach to fighting HIV. "This represents potentially a new class of drugs with activity against HIV," study co-author Marina Caskey of New York's Rockefeller University told AFP. So-called monoclonal antibodies like 3BNC117 which are cloned from a single parent immune cell, hold the promise of actually killing HIV-infected cells.
