 Progesterone May Not Lower Risk of Repeated Miscarriage Pregnant women who have had several miscarriages in the past are sometimes given progesterone supplements, in hopes of avoiding another miscarriage. In the study, researchers found no difference in birth rates between women who received progesterone treatments during their first trimester of pregnancy and those who received a placebo at that time. Among the women given the supplements, 65.8 percent maintained their pregnancy, compared to 63.3 percent of those given the placebo.

Dr. Richard Sacra, who works for the Christian mission organization SIM USA, contracted Ebola last year while caring for pregnant women in Liberia during the rise of the Ebola outbreak there. Read More »Why Menstruation Remains a Medical Mystery Humans are among the few species in which the process occurs, and although researchers have ideas about why menstruation happens, there are many unknowns. But a better understanding of the hows and whys of menstruation is needed, researchers say. "There's so much we don't understand about why this repeated event of shedding and repair happens," said Dr. Hilary Critchley, an ob-gyn and reproductive health researcher at the University of Edinburgh in Scotland.

In the study, researchers looked at an epidemic of the virus on Reunion Island, in the Indian Ocean near Madagascar, that lasted from 2005 to 2006 and sickened 300,000 people. As a result of their infections, 24 people developed encephalitis, which is inflammation of the brain, and four of these people died from their infection.

Although infectious disease experts expect to see new cases crop up shortly after a country is declared Ebola-free — often because of cases that weren't accounted for — in this case, Liberia had gone several months without any new Ebola cases, Adalja said. Liberia was first declared Ebola-free in May, but then a new case was confirmed in July.

The technology utilizes the process of photosynthesis by algae, one of the most common microorganisms on earth, according to a Concordia University engineering professor leading the research. Algae naturally creates electrons during photosynthesis, and metal probes stuck into the plant can capture that energy and transfer it into electricity for batteries, he said on Wednesday.

| Fan-Designed Lego Saturn V Moon Rocket Qualifies for Product Review Read More » U.S. Air Force official sees issues with space launch priorities By Andrea Shalal WASHINGTON (Reuters) - The United States could struggle to promote competition in its space launch program while also maintaining two independent ways to launch satellites and ending U.S. reliance on Russian rocket engines, a top U.S. Air Force official said on Tuesday. ULA, the monopoly provider of such launches since its creation in 2006, said it was unable to submit a bid in compliance with the competition's rules because of how the contest was structured, and because it lacked Russian-built RD-180 engines for its Atlas 5 rocket. The Pentagon last month refused to grant ULA a waiver from a U.S. law that banned use of the Russian engines for military and spy satellite launches after 2019.

People may feel good about themselves after acting charitably, feeling like they have a license to behave a little worse later, said study leader Marijn Meijers, a psychologist at the University of Amsterdam. "After you do something moral or laudable, you're more likely to behave a little less laudable," Meijers told Live Science.

The patients are infected with a strain of E. coli called O157:H7, which produces a harmful toxin called Shiga toxin. Five people have been hospitalized, and two of those people have developed a type of kidney failure called hemolytic uremic syndrome, which can be caused by the Shiga toxin.

Captagon is actually a combination of two drugs, theophylline and amphetamine, said Nicolas Rasmussen, a professor of history and philosophy of science at the University of New South Wales in Australia. The combination itself is inactive in the body, but when the body breaks it down into the two component parts, each part becomes active, Rasmussen told Live Science.

"The primary reason Thanksgiving can be difficult for GERD sufferers is that people tend to overstuff themselves," said Dr. Jacqueline Wolf, a gastroenterologist at Beth Israel Deaconess Medical Center in Boston. People with GERD can get into trouble by eating too much overall, eating too much within a short time and eating bothersome foods that frequently trigger reflux, Wolf said.

A kinetic device in the suit's gloves produces a tremor akin to that caused by some illicit drugs. Random flashing lights in the goggles' peripheral area, allied to hallucinogenic-type sounds in the headphones, combine to disorientate drivers.
