A study by researchers at Hospital for Special Surgery and Harvard Medical School suggests new guidelines may be in order for evaluating and treating lower extremity pain. Investigators set out to determine if there was a relation between foot pain and lower extremity joint pain, and they found a significant association between foot pain and knee or hip pain.
Significantly fewer African-Americans, Hispanics, Asians and non-Hispanic whites say 'lack of trust' is a reason why individuals do not participate in clinical trials, indicating a more favorable perception of this research. In a recent public opinion survey commissioned by Research!America, the percentage of respondents citing 'lack of trust' as a reason declined by as much as 15% among minority groups and the population overall, compared to the results of a 2013 survey.
For the first time, scientists have used Positron Emission Tomography (PET) imaging to study brain inflammation following Zika virus infection in mice, according to a study recently published online in Molecular Imaging and Biology. Traditional methods of infectious disease research using animal models provide limited information about disease progression until the study's endpoint, when investigators can analyze tissues from those animals. Imaging studies allow longitudinal studies of the same animal during the course of infection.
Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have reported. Analysis of satellite data by NSIDC and NASA showed that at 1.79 million square miles (4.64 million square kilometers), this year's Arctic sea ice minimum extent is the eighth lowest in the consistent long-term satellite record, which began in 1978.
Astrophysicists from Moscow State University have found a new way to estimate the mass of supermassive black holes outside our galaxy, even if these holes are barely detectable. The results of the study were published in the Astronomy and Astrophysics journal
A deadly amphibian disease called severe Perkinsea infections, or SPI, is the cause of many large-scale frog die-offs in the United States, according to a new study by the US Geological Survey.
More than 40 percent of American teens are now getting vaccinated against human papillomavirus (HPV). But, despite HPV infection being associated with reduced semen quality and lower pregnancy rates, there is still public concern about whether the HPV vaccine itself could affect future fertility.
Whispering gallery mode resonators rely on a phenomenon similar to an effect observed in circular galleries, and the same phenomenon applies to light. When light is stored in ring-shaped or spherical active resonators, the waves superimpose in such a way that it can result in laser light. This week in APL Photonics, investigators report a new type of dye-doped WGM micro-laser that produces light with tunable wavelengths.
Workers who were likely exposed to dispersants while cleaning up the 2010 Deepwater Horizon oil spill experienced a range of health symptoms including cough and wheeze, and skin and eye irritation, according to scientists at the National Institutes of Health (NIH). The study appeared online Sept. 15 in Environmental Health Perspectives and is the first research to examine dispersant-related health symptoms in humans.
The cyber team led by Dr. Mordechai Guri, head of research and development for BGU's Cyber Security Research Center (CSRC), shows how IR can be used to create a covert communication channel between malware installed on an internal computer network and an attacker located hundreds of yards outside or even miles away with direct line of sight. The attacker can use this channel to send commands and receive response messages.
