MADISON, Wis. — Wisconsin is famous for its ice fishers — the stalwarts who drill holes through lake ice in the hope of catching a winter dinner. Less well known are the state's big-league ice drillers — specialists who design huge drills and use them to drill deep into ice in Greenland and Antarctica, places where even summer seems like winter. The quarry at these drills includes some of the biggest catches in science. A hot-water drill designed and built at the University of Wisconsin-Madison's Space Science and Engineering Center (SSEC) and the ...

Philadelphia, PA, October 30, 2014 – A common complication, gestational diabetes affects approximately 6-7% of pregnant women. Currently, screening is done in two steps to help identify patients most at risk; however, the suggested levels for additional testing were based on singleton pregnancy data. Now investigators have analyzed data from twin pregnancies and have determined that the optimal first step cutoff for additional screening appears to be a blood sugar level equal to or greater than 135 mg/dL for women carrying twins. Their findings are published in the ...

MAYWOOD, Ill. (Date) – During the first 24 hours after a stroke, attention to detail --such as hospital bed positioning -- is critical to patient outcomes. Most strokes are caused by blood clots that block blood flow to the brain. Sitting upright can harm the patient because it decreases blood flow and oxygen to the brain just when the brain needs more blood. Thus, it's reasonable to keep patients lying flat or as nearly flat as possible, according to a report in the journal MedLink Neurology by Loyola University Medical Center neurologist Murray Flaster, MD, ...

(Santa Barbara, Calif.) — Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ubiquitous membrane structure in the cells of the body. Dubbed Terasaki ramps after their discoverer, they reside in an organelle called the endoplasmic reticulum (ER), a network of membranes found throughout the cell and connected to and surrounding the cell nucleus. Now, a trio of scientists, including UC Santa Barbara biological physicist ...

The heart holds its own pool of immune cells capable of helping it heal after injury, according to new research in mice at Washington University School of Medicine in St. Louis. Most of the time when the heart is injured, these beneficial immune cells are supplanted by immune cells from the bone marrow, which are spurred to converge in the heart and cause inflammation that leads to further damage. In both cases, these immune cells are called macrophages, whether they reside in the heart or arrive from the bone marrow. Although they share a name, where they originate appears ...

BOSTON — Findings published in the Archives of Physical Medicine and Rehabilitation show that imperceptible vibratory stimulation applied to the soles of the feet improved balance by reducing postural sway and gait variability in elderly study participants. The vibratory stimulation is delivered by a urethane foam insole with embedded piezoelectric actuators, which generates the mechanical stimulation. The study was conducted by researchers from the Institute for Aging Research (IFAR) at Hebrew SeniorLife, Beth Israel Deaconess Medical Center, the Wyss Institute for ...

A significant breakthrough in laser technology has been reported by the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. Scientists led by Xiang Zhang, a physicist with joint appointments at Berkeley Lab and UC Berkeley, have developed a unique microring laser cavity that can produce single-mode lasing even from a conventional multi-mode laser cavity. This ability to provide single-mode lasing on demand holds ramifications for a wide range of applications including optical metrology and ...

Lab-grown tissues could one day provide new treatments for injuries and damage to the joints, including articular cartilage, tendons and ligaments. Cartilage, for example, is a hard material that caps the ends of bones and allows joints to work smoothly. UC Davis biomedical engineers, exploring ways to toughen up engineered cartilage and keep natural tissues strong outside the body, report new developments this week in the journal Proceedings of the National Academy of Sciences. "The problem with engineered tissue is that the mechanical properties are far from those ...

Washington, DC—The Endocrine Society today issued a Clinical Practice Guideline (CPG) for the diagnosis and treatment of acromegaly, a rare condition caused by excess growth hormone in the blood. The CPG, entitled "Acromegaly: An Endocrine Society Clinical Practice Guideline," appeared in the November 2014 issue of the Journal of Clinical Endocrinology and Metabolism (JCEM), a publication of the Endocrine Society. Acromegaly is usually caused by a non-cancerous tumor in the pituitary gland. The tumor manufactures too much growth hormone and spurs the body to overproduce ...

Chicago, October 30, 2014—Analysis of data from an institutional patient registry on stereotactic body radiotherapy (SBRT) indicates excellent long-term, local control, 79 percent of tumors, for medically inoperable, early stage lung cancer patients treated with SBRT from 2003 to 2012, according to research presented today at the 2014 Chicago Multidisciplinary Symposium in Thoracic Oncology. The Symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study ...

BUFFALO, N.Y. – You have to be at least 2 years old to be covered by U.S. dietary guidelines. For younger babies, no official U.S. guidance exists other than the general recommendation by national and international organizations that mothers exclusively breastfeed for at least the first six months. So what do American babies eat? That's the question that motivated researchers at the University at Buffalo School of Medicine and Biomedical Sciences to study the eating patterns of American infants at 6 months and 12 months old, critical ages for the development of ...

NOAA's GOES-West satellite captured an image of the birth of the Eastern Pacific Ocean's twenty-first tropical depression, located far south of Acapulco, Mexico. NOAA's GOES-West satellite gathered infrared data on newborn Tropical Depression 21E (TD 21E) and that data was made into an image by NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland. At 1200 UTC (9 a.m. EDT), the GOES-West image showed that thunderstorms circled the low-level center and extended northeast of the center indicating that southwesterly wind shear was affecting ...

Correct spatial organization of motor neurons, interneurons and dorsal interneurons along the dorsal/ventral axis was observed. This study has been published online by the American journal "Stem Cell Reports" on 30.10.2014. For many years Elly Tanaka and her research group have been studying ...

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world's energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. In many popular applications — video rendering, for instance — users probably wouldn't notice the difference, and it could significantly improve energy efficiency. At ...

Global warming is altering the reproduction of plants and animals, notably accelerating the date when reproduction and other life processes occur. A study by the University of Uppsala (Sweden), including the participation of Spanish researcher Germán Orizaola, has discovered that some amphibians are capable of making their offspring grow at a faster rate if they have been born later due to the climate. Over recent decades many organisms, both plants and animals, have experienced a notable advance in the date when many of their life processes (like reproduction, migration ...

Soon, many will turn back the hands of time as part of the twice-annual ritual of daylight savings time. That means remembering to change the alarm clock next to the bed, which will mean an extra hour of sleep before getting up in the morning. But for some diabetics who use insulin pumps, Saleh Aldasouqi, associate professor of medicine at Michigan State University, suggests that remembering to change the time on this device should be the priority. "Some diabetes patients who use insulin pumps may forget to change the clock that is found in these devices," said diabetes ...

Rochelle, NY, October 30, 2014—Several companies are developing spacecraft designed to take ordinary citizens, not astronauts, on short trips into space.

Tropical Cyclone Nilofar was closing in on the border between Pakistan and northwestern India on Oct. 30 when NASA's Terra satellite passed overhead from space. Wind shear continued to affect the storm making it appear more like a comet with a tail, than a tropical cyclone. The MODIS or Moderate Resolution Imaging Spectroradiometer instrument that flies aboard NASA's Terra satellite captured a visible image of Nilofar on Oct. 30 at 06:35 UTC (2:35 a.m. EDT). Nilofar was still being affected by southwesterly wind shear, which was blowing the clouds and showers to the northeast. ...

Chicago, October 30, 2014 – The Society of Thoracic Surgeons (STS) has released new clinical practice guidelines for treating cancer of the esophagus and gastroesophageal junction (area where the esophagus meets the stomach). The guidelines, published in the November 2014 issue of The Annals of Thoracic Surgery, include nine evidence-based recommendations that address issues related to multimodality care, including neoadjuvant therapy (chemotherapy and radiation therapy given prior to surgery). The goal of this therapy is to reduce the extent of cancer before an ...

Chicago, October 30, 2014—Analysis of 607 small cell lung cancer (SCLC) lung tumors and neuroendocrine tumors (NET) identified common molecular markers among both groups that could reveal new therapeutic targets for patients with similar types of lung cancer, according to research presented today at the 2014 Chicago Multidisciplinary Symposium in Thoracic Oncology. The Symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study of Lung Cancer (IASLC) and ...

WASHINGTON – Young adults ages 18-26 should be viewed as a separate subpopulation in policy and research, because they are in a critical period of development when successes or failures could strongly affect the trajectories of their lives, says a new report from the Institute of Medicine and National Research Council. The committee that wrote the report found that young adults' brains and behaviors continue maturing into their 20s, and they face greater challenges achieving independence than their predecessors did, have lengthened pathways into adulthood, and are ...

The lemur, Javan rhino and Santa Cruz kangaroo rat are all lonesome animals. As endemic species, they live in habitats restricted to a particular area due to climate change, urban development or other occurrences. Endemic species are often endangered, and a University of Tennessee, Knoxville, study finds that saving them is more important to biodiversity than previously thought. Joe Bailey, associate professor in the Department of Ecology and Evolutionary Biology, and his colleagues from the University of Tasmania in Australia looked at endemic eucalyptus found in ...

Chicago, October 30, 2014—Patients who received post-operative radiation therapy (PORT), radiation therapy after surgery, lived an average of four months longer when compared to the patients who had the same disease site, tumor histology and treatment criteria and who did not receive PORT, according to research presented today at the 2014 Chicago Multidisciplinary Symposium in Thoracic Oncology. The Symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the ...
