The use of insects as indicators of post-mortem displacement is a familiar technique depicted on many crime investigation TV shows. In reality, this practice is far from clear-cut. To cut through the hype, researchers have looked across existing studies to review how exactly insects have been used in legal investigations and to what extent these methods have been useful.
Heart failure can quickly develop or become worse during a hospital stay, even when it isn’t the primary cause for admission. Hospitals and clinicians must be diligent to identify patients at risk for secondary heart failure as they aim to improve outcomes, contain costs and prevent readmissions, according to an article in Critical Care Nurse.
Iowa State's Edward Yu has spent years studying the structures bacteria use to resist antibiotics. He and his research group recently published two more papers describing the pumps and transporters that certain disease-causing bacteria use to keep antibiotics away.
Postmenopausal women who have a history of gum disease also have a higher risk of cancer, according to a new study of more than 65,000 women.
Despite being saddled with many factors associated with drug and alcohol problems, undocumented immigrants are not increasing the prevalence of drug and alcohol crimes and deaths in the United States, according to a new University of Wisconsin-Madison study published in the American Journal of Public Health.
For infants with skull flattening related to sleep position, starting helmet therapy at a younger age, especially before 24 weeks, increases the treatment success rate, suggests a study in the August issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
A new study published in the HSS Journal by HSS anesthesiologist Michael K. Urban, MD, PhD, sheds light on reducing cardiac complications in orthopedic surgery.
Researchers at Binghamton University have developed a new drug that may limit the progression of Parkinson’s disease while providing better symptom relief to potentially hundreds of thousands of people with the disease.
A newly discovered collective rattling effect in a type of crystalline semiconductor blocks most heat transfer while preserving high electrical conductivity – a rare pairing that scientists say could reduce heat buildup in electronic devices and turbine engines, among other possible applications.
Shrinking the annual Gulf of Mexico "dead zone" down to the size of Delaware will require a 59-percent reduction in the amount of nitrogen runoff that flows down the Mississippi River from as far away as the Corn Belt
A team of Florida State University scientists has discovered that chemical weathering, a process in which carbon dioxide breaks down rocks and then gets trapped in sediment, can happen at a much faster rate than scientists previously assumed and could potentially counteract some of the current and future climate change caused by humans.
A study by researchers at NewYork-Presbyterian/Columbia University Medical Center and published in JACC: Heart Failure, a journal of the American College of Cardiology Foundation, allays concerns among cardiologists that aspirin could increase the risk of hospitalization and death related to heart failure for patients with heart failure who take one of the first-line therapies: angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs).
The delayed arrival of immune cells after cancer therapy is well documented and critical for responses to chemotherapy and radiation, yet the events underlying their induction remain poorly understood. Now, Penn researchers have discovered how DNA damage is a clarion call for the immune system.
Los Alamos National Laboratory has produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths.
A new light-trapping sensor, developed by a University at Buffalo-led team of engineers and described in an Advanced Optical Materials study, makes infrared absorption more sensitive, inexpensive and versatile. It may improve scientists’ ability use to sleuth out performance-enhancing drugs in blood samples, tiny particles of explosives in the air and more.
A new study from the USC Viterbi School of Engineering’s Signal Analysis and Interpretation Lab (SAIL)--which creates automatic tools for signal analysis and linguistic assessment --uncovers how media communicates about gender, race and age finding that in the majority of films, females roles are not central to the plot.
Writing today in the journal Cancer Research, James DeGregori, PhD, deputy director of the University of Colorado Cancer Center offers evidence that it is forces of evolution driven by natural selection acting in the ecosystem of the body that, in the presence of tissue damage, allow cells with dangerous mutations to thrive.
A University of Washington-led study has found that for Asian Americans, those who appear heavier not only are perceived to be more "American," but also may be subject to less prejudice directed at foreigners than Asian Americans who are thin.
Lightweight composite material for energy storage in flexible electronics, electric vehicles and aerospace applications has been experimentally shown to store energy at operating temperatures well above current commercial polymers.
Lawrence Livermore scientists have developed a technique that helps extract hydrogen from water efficiently and cheaply.
