A review of more than 9,000 U.S. patients with severe COVID-19 infection showed less than 1% contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test. Those are the findings from a study conducted by researchers from the University of Missouri School of Medicine and MU Health Care.
June 15, 2021 - Canadian researchers have discovered that a bee thought to be one of the rarest in the world, as the only representative of its genus, is no more than an unusual specimen of a widespread species.
A recent UCLA clinical trial has shown encouraging results in helping daily smokers who are also heavy drinkers quit smoking and cut down their alcohol intake.
The study of 165 people tested two prescription drugs -- varenicline, for smoking addiction, and naltrexone, which is used to treat alcoholism. Studies have shown that varenicline, marketed under the brand name Chantix, may also be effective in reducing alcohol consumption.
A new model that applies artificial intelligence to carbohydrates improves the understanding of the infection process and could help predict which viruses are likely to spread from animals to humans. This is reported in a recent study led by researchers at the University of Gothenburg.
Researchers at the University of Maryland School of Medicine (UMSOM) have developed two rapid diagnostic tests for COVID-19 that are nearly as accurate as the gold-standard test currently used in laboratories. Unlike the gold standard test, which extracts RNA and uses it to amplify the DNA of the virus, these new tests can detect the presence of the virus in as little as five minutes using different methods.
WASHINGTON -- Researchers have fabricated a magnetically driven rotary microfilter that can be used to filter particles inside a microfluidic device. They made the tiny turning filter by creating a magnetic material that could be used with a very precise 3D printing technique known as two-photon polymerization.
GAINESVILLE, Fla. --- An international research team has described a new species of Oculudentavis, providing further evidence that the animal first identified as a hummingbird-sized dinosaur was actually a lizard.
PULLMAN, Wash. - You can take a fish out of toxic water, but its epigenetic mutations will remain for at least two generations.
A research team led by Washington State University scientists analyzed the epigenetics--molecular factors and processes that determine whether genes are turned on or off--of a group of Poecilia mexicana fish, or Atlantic molly, that live in springs naturally high in hydrogen sulfide, which is normally toxic to most organisms.
EVANSTON, Ill. --- The human gut is more than a source of instinct.
A new Northwestern University study is the first to explicitly address the gut microbiome as a pathway to understanding how environmental inequities could lead to health disparities.
Biological anthropologist Katherine Amato, assistant professor of anthropology at the Weinberg College of Arts and Sciences at Northwestern, is the study's lead author.
The use of 'ice' flavoured e-cigarettes may be common and positively associated with conventional smoking and nicotine dependence among young adults, suggests research published online in the journal Tobacco Control.
And it's unclear where these' hybrid' vapes, combining fruit/sweet and cooling flavours, fit into current or future regulatory frameworks, which apply restrictions according to distinct flavour categories, point out the study authors.
Reston, VA (Embargoed until 7:30 p.m. EDT, Monday, June 14, 2021)--A protein that is critical in cancer cell metabolism has been imaged for the first time with a newly developed radiopharmaceutical, 18F-DASA-23. Imaging with this novel agent has the potential to improve the assessment of treatment response for patients, specifically those with brain tumors. This study was presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.
Reston, VA (Embargoed until 7:30 p.m. EDT, Monday, June 14, 2021)--In patients with mild cognitive impairment, taking lipophilic statins more than doubles their risk of developing dementia compared to those who do not take statins. According to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting, positron emission tomography (PET) scans of lipophilic statin users revealed a highly significant decline in metabolism in the area of the brain that is first impacted by Alzheimer's disease.
When Erin Hecht was earning her Ph.D. in neuroscience more than a decade ago, she watched a nature special on the Russian farm-fox experiment, one of the best-known studies on animal domestication.
Like amyloid plaque, the genetic variant APOE4 has long been associated with Alzheimer's disease, but still little is known about the role the gene plays in the disease process.
Osaka, Japan - Researchers from the Graduate School of Engineering and the Center for Quantum Information and Quantum Biology at Osaka University unveiled a new solid state second-harmonic generation (SHG) device that converts infrared radiation into blue light. This work may lead to a practical daily-use deep ultraviolet light source for sterilization and disinfection.
