Two new species of carabid beetles found in Ethiopia

Two new species of carabid beetles found in Ethiopia
2014-09-11
(Press-News.org) There are more than 150 species of beetles in the genus Calathus, 17 of which have only been found in the mountains of the Ethiopian Highlands. Now scientists have found two new ones — Calathus juan and Calathus carballalae — and have described them in Annals of the Entomological Society of America.

C. juan is named for Juan Novoa, the son of one of the authors, in recognition of his help on various beetle-collecting expeditions. Adults are black and shiny, and are 9.5-11.5 millimeters long. It was found under stones at the base of giant, tree-like plants called lobelias (Lobelia rhynchopetalum) at almost 3,600 meters above sea level.

C. carballalae is named for Regina Carballal, the wife of the first author, also for collaboration on Coleoptera-collecting expeditions. It was found under stones on barren soil nearly 4,150 meters above sea level.

How salt causes buildings to crumble

2014-09-11
This news release is available in German. Historic stone buildings are tourist magnets. The Jordanian rock city of Petra, the medieval town of Rhodes in the Aegean Sea and the sandstone temples at Luxor, Egypt, for example, attract hundreds of thousands of visitors each year. These cultural assets all have one thing in common: they suffer from weathering caused by salts. These crystallise inside the porous building materials and generate enough force for the stone to break or crumble. The same problem also occurs in concrete buildings in this country. Researchers at ...

Ticks that vector Lyme disease move west into North Dakota

2014-09-11
According to the U.S. Centers for Disease Control, there are more than 300,000 cases of Lyme disease in the U.S. each year. Last year, most Lyme disease cases reported to the CDC were concentrated heavily in the Northeast and upper Midwest, with 96 percent of cases in 13 states. In fact, the disease gets its name from the northeastern town of Lyme, Connecticut, where it was first discovered. However, a new article published in the Journal of Medical Entomology reports that the ticks that vector Lyme disease — Ixodes scapularis, also known as blacklegged ticks or deer ...

Study finds high protein diets lead to lower blood pressure

2014-09-11
(Boston)--Adults who consume a high-protein diet may be at a lower risk for developing high blood pressure (HBP). The study, published in the American Journal of Hypertension, by researchers from Boston University School of Medicine (BUSM), found participants consuming the highest amount of protein (an average of 100 g protein/day) had a 40 percent lower risk of having high blood pressure compared to the lowest intake level. One of three U.S. adults has hypertension and 78.6 million are clinically obese, a risk factor for the development of hypertension. Because of the ...

New defense mechanism against viruses discovered

2014-09-11
This news release is available in German. When it comes to defence against viruses, the immune system has an arsenal of weapons at its disposal including killer cells, antibodies and messenger molecules, to name just a few. When a pathogen attacks the body, the immune system usually activates the appropriate mechanisms. However, some of the mechanisms do not have to be triggered; they are continuously active as a standing army. Researchers from ETH Zurich, in collaboration with scientists from the University of Bern, have now discovered a new form of this so-called ...

UM research reveals secrets of animal weapons

2014-09-11
MISSOULA – From antlers to horns, humans have long been fascinated by animals' ability to defend themselves with their natural-born weapons. But until now, no studies have directly tested whether those weapons perform better at the animals' own style of fighting than they would using the fighting style of another species. Researchers at the University of Montana recently discovered each species' weapons are structurally adapted to meet their own functional demands of fighting. The groundbreaking research, conducted over the past year by UM doctoral student Erin McCullough ...

Excitonic dark states shed light on TMDC atomic layers

Excitonic dark states shed light on TMDC atomic layers
2014-09-11
A team of Berkeley Lab researchers believes it has uncovered the secret behind the unusual optoelectronic properties of single atomic layers of transition metal dichalcogenide (TMDC) materials, the two-dimensional semiconductors that hold great promise for nanoelectronic and photonic applications. Using two-photon excitation spectroscopy, the researchers probed monolayers of tungsten disulfide, one of the most promising of 2D materials, and found evidence for the existence of excitonic dark states – energy states in which single photons can be neither absorbed nor emitted. ...

Cutting health-care costs 1 appendix at a time

2014-09-11
(SALT LAKE CITY)—Consumer price comparison is almost nonexistent in the U.S. health care system, but a new study shows that when given the choice between a less costly "open" operation or a pricier laparoscopy for their children's appendicitis, parents were almost twice as likely to choose the less expensive procedure – when they were aware of the cost difference. The study, published in the September issue of Annals of Surgery online, shows that providing pricing information upfront can influence patient choice of surgical procedures and potentially lead to cost savings ...

Endometriosis a burden on women's lives

2014-09-11
Endometriosis often takes a long time to be diagnosed and affects all areas of a women's life, a study has found. Research led by Monash University's Kate Young published in the Journal of Family Planning and Reproductive Health Care found that endometriosis affects women's sex lives, personal relationships, work life, and emotional wellbeing. Endometriosis is a chronic, recurring disease that is experienced by approximately 10 per cent of women worldwide. Common symptoms include painful menstruation, heavy menstrual bleeding, painful sex and infertility. Ms Young, ...

Perfect focus through thick layers may bring better vision to medicine

Perfect focus through thick layers may bring better vision to medicine
2014-09-11
WASHINGTON, Sept. 11, 2014—Zooming in on diseased tissue or scanning fragile biological samples are essential tools in medicine and biological research, but this often requires peering through layers of tissue and other materials that can blur and distort the image. Certain modern microscopes can compensate for this, but only for weak aberrations or by using invasive "guide stars," imaging aids that provide a stable reference point. In a first-of-its-kind demonstration, published today in The Optical Society's (OSA) new high-impact journal Optica, a team of researchers ...
