The Gastropoda, more commonly known as snails and slugs, are a large group of animals within the phylum Mollusca. Gastropоds species are extremely diverse in forms and sizes, ranging from microscopic to large. About 50 species of snails are currently considered to inhabit Skadar Lake, the largest on the Balkan Peninsula.

Bacteria appear to speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Certain genes are in prime collision paths for the moving molecular machineries that read the DNA code, as University of Washington scientists explain in this week's edition of Nature.
PHILADELPHIA — A new diagnostic test that uses a scientific technique known as metabolomic analysis may be a safe and easy screening method that could improve the prognosis of patients with pancreatic cancer through earlier detection.
Researchers examined the utility of metabolomic analysis as a diagnostic method for pancreatic cancer and then validated the new approach, according to study results published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
African forest elephants are being poached out of existence. A study just published in the online journal PLOS ONE and supported in part by San Diego Zoo Global shows that a staggering 62% of all forest elephants have been killed across their range in central Africa, for their ivory over the past decade. The severe decline indicates what researchers fear is the eminent extinction of this species.
Cincinnati, OH, March 29, 2013 -- Although scientific evidence suggests that vaccines do not cause autism, approximately one-third of parents continue to express concern that they do; nearly 1 in 10 parents refuse or delay vaccinations because they believe it is safer than following the Centers for Disease Control and Prevention's (CDC) schedule. A primary concern is the number of vaccines administered, both on a single day and cumulatively over the first 2 years of life.
Researchers at Papworth Hospital, the University of Cambridge and the Wellcome Trust Sanger Institute have discovered why a new type of dangerous bacterial infection has become more common among people with Cystic Fibrosis around the world.
Through their ground-breaking research, the team has developed new measures to protect Cystic Fibrosis patients.
Sometimes, little things can add up to a lot.
In short, that's the message of a research study on small dams, streams and pollution by Steve Powers, a postdoctoral researcher at the University of Notre Dame's Environmental Change Initiative (ECI).
"Small dams, reservoirs and ponds trap water pollution, which provides an important benefit to water resources," Powers said. "This is especially relevant in agricultural lands of the Midwest U.S., where there are lots of small, but aging dams."
A new research paper by a team of researchers from the University of Notre Dame's Environmental Change Initiative (ECI) demonstrates how two cutting-edge technologies can provide a sensitive and real-time solution to screening real-world water samples for invasive species before they get into our country or before they cause significant damage.
One of the leading causes of death in the United States is sudden cardiac arrest, which claims the lives of more than 325,000 people each year. In a study published in the April issue of the journal Resuscitation, Beaumont doctors found that cardiac arrests in K-12 schools are extremely rare, less than 0.2 percent, but out of 47 people who experienced cardiac arrest over a six-year period at K-12 schools, only 15 survived.
STANFORD, Calif. — When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum tubes and electricity. Today, computers use transistors made from highly engineered semiconducting materials to carry out their logical operations.
LA JOLLA, CA – March 28, 2013 – A team led by scientists from The Scripps Research Institute (TSRI) and the International AIDS Vaccine Initiative (IAVI) has unveiled a new technique for vaccine design that could be particularly useful against HIV and other fast-changing viruses.
Home hot water heater temperatures are too high, warns a team of researchers from the Johns Hopkins Bloomberg School of Public Health. Despite the adoption of voluntary standards by manufacturers to preset hot water heater temperature settings below the recommended safety standard of 120°F, temperatures remain dangerously high for a significant proportion of homes, presenting a scald hazard for young children and the elderly. The report is published in the March 2013 issue of Journal Of Burn Care Research.
Expanding Medicaid in Pennsylvania under the Affordable Care Act would boost federal revenue to the state by more than $2 billion annually and provide 340,000 residents with health insurance, according to a new RAND Corporation study.
The increased federal spending on health care in Pennsylvania would provide a $3 billion boost in economic activity and sustain more than 35,000 jobs, according to the analysis.
Physical activity and its relation to obesity has been studied for decades by researchers; however, almost no one has studied the reverse – obesity's effect on physical activity.
So BYU exercise science professor Larry Tucker decided to look at the other side of the equation to determine if obesity leads to less activity. The findings, no surprise, confirmed what everyone has assumed for years.
