A total of 1,121 injuries requiring emergency department treatment were recorded in Delaware during the past three summers for patients hurt by ocean waves. Injuries range from simple sprains and strains to extremity fractures, blunt organ trauma and fractures of the cervical spine. There were three fatalities attributed to surf zone injuries during the study period. The most common ailments were broken collarbones, dislocated and separated shoulders, neck pain, and ankle and knee sprains. (more…)
LARAMIE, Wyo. — Migratory elk are coming back from Yellowstone National Park with fewer calves due to drought and increased numbers of big predators – two landscape-level changes that are reducing the benefits of migration with broader implications for conservation of migratory animals, according to a new study published in the journal Ecology.
The new study by the Wyoming Cooperative Fish and Wildlife Research Unit – a joint program involving U.S. Geological Survey, the University of Wyoming, and the Wyoming Game and Fish Department, describes a long-term decline in the number of calves produced annually by the Clarks Fork herd, a population of about 4000 elk whose migrants travel annually between winter ranges near Cody, Wyoming and summer ranges within Yellowstone National Park. Migratory elk experienced a 19 percent depression in rates of pregnancy over the four years of the study and a 70 percent decline in calf production over 21 years of monitoring by the WGFD, while the elk that did not migrate, known as resident elk, in the same herd experienced high pregnancy and calf production and are expanding their numbers and range into private lands outside of the park.

Sixteen years ago, Jason Hill stood before some 30 students in one of his first classes as a teaching assistant at the University of Minnesota. This June, more than 14,000 students will log on to take his course, Sustainability of Food Systems: A Global Life Cycle Perspective.
Hill’s class is among the first five massive open online courses (MOOCs) the U of M is offering (for free) through a partnership with Coursera, a leading MOOC platform. (more…)
Bubble baths and soapy dishwater, the refreshing head on a beer and the luscious froth on a cappuccino. All are foams, beautiful yet ephemeral as the bubbles pop one by one. Now, two researchers from the Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley have described mathematically the successive stages in the complex evolution and disappearance of foamy bubbles, a feat that could help in modeling industrial processes in which liquids mix or in the formation of solid foams such as those used to cushion bicycle helmets.

For Other Behaviors, People Care Less about Meeting Norms
COLUMBUS, Ohio – People will lie about their sexual behavior to match cultural expectations about how men or women should act – even though they wouldn’t distort other gender-related behaviors, new research suggests.
The study found that men were willing to admit that they sometimes engaged in behaviors seen by college students as more appropriate for women, such as writing poetry. The same was true for women, who didn’t hide the fact that they told obscene jokes, or sometimes participated in other “male-type” deeds. (more…)
Researchers invent solution that seamlessly brings together 4 integrated chips and 64 antennas in a single package for mobile and transportation solutions Proven SiGe BiCMOS prototype takes advantage of under-utilized short-wavelength frequency
SEATTLE, WA – 04 Jun 2013: Scientists from IBM have achieved a milestone in creating a phased-array transceiver that contains all of the millimeter-wave components necessary for both high data-rate communications and advanced-resolution radar imaging applications. The newly demonstrated integrated circuits (ICs) tackle data bottleneck issues for mobile communications applications and allow radar-imaging technology to be scaled down to the size of a computer laptop.
Advanced radio frequency integration has been a key driver in the explosive growth of mobile device capability and sophistication. Millimeter-wave bandwidth has the ability to support Gb/s wireless communications, dramatically expanding opportunities for mobile backhaul, small cell infrastructure, and data center overlay network deployment.

There are worrisome racial, economic, educational, and gender gaps in awareness about the lifesaving vaccine for human papilloma virus (HPV), a Yale Cancer Center study has found. The study is being presented at the 2013 annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago.
HPV is a primarily sexually transmitted virus most widely known for causing cervical cancer, but it can also cause anal cancer, certain oral cancers, and cancers of the sexual organs of both women and men. (more…)
Researchers at Washington University in St., Louis, using powerful algorithms developed by computer scientists at Brown University, have assembled the most complete genetic profile yet of acute myeloid leukemia, an aggressive form of blood cancer. Findings are reported in the New England Journal of Medicine.
PROVIDENCE, R.I. [Brown University] — Powerful data-sifting algorithms developed by computer scientists at Brown University are helping to untangle the profoundly complex genetics of cancer.
In a study reported on May 1, 2013, in the New England Journal of Medicine, researchers from Washington University in St. Louis used two algorithms developed at Brown to assemble the most complete genetic profile yet of acute myeloid leukemia (AML), an aggressive form of blood cancer. The researchers hope the work will lead to new AML treatments based on the genetics of each patient’s disease. (more…)
