Applying the principle of mediocrity to the Drake equation, a probabilistic estimate of the number of intelligent species in the universe, leads to the conclusion that technological species go extinct early in their development.
Patients who choose to receive alternative therapy as treatment for curable cancers instead of conventional cancer treatment have a higher risk of death, according to researchers from the Cancer Outcomes, Public Policy and Effectiveness Research (COPPER) Center at Yale School of Medicine and Yale Cancer Center.
A team of researchers has developed a new mechanism that uses machine-learning algorithms to distinguish between genuine and counterfeit versions of the same product.
Writing Aug. 11 in the journal Environmental Research Letters, University of Wisconsin-Madison Professor Tracey Holloway, an expert on air quality, and her former graduate student Olivia Sanderfoot, sort through nearly 70 years of the scientific literature to assess the state of knowledge of how air pollution directly affects the health, well-being, reproductive success and diversity of birds.
PPPL research performed with collaborators from Princeton University and the Institute for Advanced Computational Science at the State University of New York at Stony Brook has shown how plasma causes exceptionally strong, microscopic structures known as carbon nanotubes to grow.
The ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help birds and bats near offshore wind turbines.
The opioid crisis in the United States is resulting in increased admissions to hospital intensive care units and in increased numbers of ICU deaths from opioid overdoses, according to new research published online, ahead of print in the Annals of the American Thoracic Society.
Results of a small clinical trial show promise for treating a rare neurodegenerative condition that typically kills those afflicted before they reach age 20. The disease, called Niemann-Pick type C (NPC), causes cholesterol to build up in neurons, leading to a gradual loss of brain function. In the drug trial, researchers have shown that treatment with a type of sugar molecule called cyclodextrin slows progression of the disease.
Patients with different chronic pain diagnoses recorded similar brain changes, a new study finds, suggesting a need for new treatment approaches.
• Investigators observed a step-wise increase in the risk of atrial fibrillation with decreasing kidney function. Compared with patients without kidney disease, those with severe kidney disease had a two-fold higher risk for developing atrial fibrillation. • This link held even after accounting for a range of possible contributors, including measures of cardiovascular health, and it was consistent across subgroups of participants.
Heavy drinking can have a number of negative consequences, including sex that is later regretted. Low sensitivity (LS) to alcohol’s effects – which characterizes the person who can “drink everyone under the table” – is a known risk factor for heavy drinking and its consequences. This study investigated LS and regretted sex from an unusual perspective, asking whether LS could be protective in some contexts, given that LS drinkers are generally less impaired from drinking at a given level. More specifically, the investigators tested whether LS was associated with differences in reports by men and women of alcohol-related regretted sex.
In a study published Aug. 11 in the journal Science, researchers from the University of Wisconsin-Madison and Temple University assessed what people in the United States think about the uses of human genome editing and how their attitudes may drive public discussion. They found a public divided on its uses but united in the importance of moving conversations forward.
An international team of scientists, led by University of California San Diego School of Medicine researchers, has created a human stem cell-based model of a rare, but devastating, inherited neurological autoimmune condition called Aicardi-Goutieres Syndrome (AGS). In doing so, the team was able to identify unusual and surprising underlying genetic mechanisms that drive AGS and test strategies to inhibit the condition using existing drugs.
A little-studied gene may explain how some liver cancer cells obtain the nutrition they need to proliferate, according to new research from the University of Maryland.
School-based mental health programs can reach large numbers of children, with increasing evidence of effectiveness in improving mental health and related outcomes, according to a research review in the September/October issue of the Harvard Review of Psychiatry. The journal is published by Wolters Kluwer.
Currently, testing for Zika requires that a blood sample be refrigerated and shipped to a medical center or laboratory, delaying diagnosis and possible treatment. Now, Washington University in St. Louis researchers have developed a test that quickly can detect the presence of Zika virus in blood. Although the new proof-of-concept technology has yet to be produced for use in medical situations, test results can be determined in minutes, and the materials do not require refrigeration.
An analysis of U.S. government data obtained by Northwestern University’s Deportation Research Clinic shows that the U.S. government detained more than 260 U.S. citizens for weeks and even years, most in private prisons under contract with Immigration and Customs Enforcement (ICE).
Researchers have created a small molecule that prevents or impedes tooth cavities in a preclinical model. The inhibitor blocks the function of a key virulence enzyme in an oral bacterium, a molecular sabotage that is akin to throwing a monkey wrench into machinery to jam the gears.
Researchers at the University of Wisconsin-Madison have developed a new measurement for the volume and activity of beta cells, the source of the sugar-regulating hormone insulin.
Proteins in archaea bend strands of DNA in a way that’s similar in eukaryotes, new research from HHMI investigator and colleagues reveals. That similarity hints at the evolutionary origin of the elaborate folding that eukaryotic cells use to cram their genome into a nucleus.
