Researchers from the University of Iowa may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes two major hallmarks of type 2 diabetes, according to new findings published Oct. 6 in Cell Metabolism.
LA JOLLA--As scientists around the world develop life-saving COVID-19 vaccines and therapies, many are still wondering exactly why the disease proves deadly in some people and mild in others.
To solve this puzzle, scientists need an in-depth understanding of how the body's many types of immune cells respond to SARS-CoV-2, the virus that causes COVID-19.
The presence of diamonds in an outcrop atop an unrealized gold deposit in Canada's Far North mirrors the association found above the world's richest gold mine, according to University of Alberta research that fills in blanks about the thermal conditions of Earth's crust three billion years ago.
Engineers at the University of California San Diego have built a squid-like robot that can swim untethered, propelling itself by generating jets of water. The robot carries its own power source inside its body. It can also carry a sensor, such as a camera, for underwater exploration.
The researchers detail their work in a recent issue of Bioinspiration and Biomimetics.
With its dazzling system of icy rings, Saturn has been a subject of fascination since ancient times. Even now the sixth planet from the sun holds many mysteries, partly because its distance away makes direct observation difficult and partly because this gas giant (which is multiple times the size of our planet) has a composition and atmosphere, mostly hydrogen and helium, so unlike that of Earth. Learning more about it could yield some insights into the creation of the solar system itself.
Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of travel. Just check the stamps in Tiago R. Simões ' passport.
AURORA, Colo. -- Olfactory sensory neurons are nasal neurons that make use of hundreds of different types of odorant receptors to analyze odorous chemicals in our external world and send that information to our brain. These neurons have the unusual ability to undergo turnover throughout life - a process understood to happen due to the special vulnerability of these neurons to environmental insults, such as viruses.
NOAA/NASA's Suomi NPP satellite captured another startling image of the August Complex of fires that has grown to over 1,000,000 acres burned (1,006,140 acres total) and because of that grim milestone the complex has been dubbed a "gigafire." The August Complex is only 58% contained. Inciweb reports that: "In the northeast zone, active behavior continues. Structures in Hidden Valley, Trinity Pines/Post Mountain, Wildwood and Platina are threatened by fire spread. Short range spotting and fire spread toward Hidden Valley has increased potential for impact to structures."
A new report suggests that lingering "brain fog" and other neurological symptoms after COVID -19 recovery may be due to post-traumatic stress disorder (PTSD), an effect observed in past human coronavirus outbreaks such as SARS and MERS.
People who have recovered from COVID-19 sometimes experience lingering difficulties in concentration, as well as headaches, anxiety, fatigue or sleep disruptions. Patients may fear that the infection has permanently damaged their brains, but researchers say that's not necessarily the case.
A new study published in Arthritis Care & Research has examined patterns of 24-hour physical activity and sleep among patients with rheumatoid arthritis, lupus, and knee osteoarthritis.
In the 172-participant study, four profiles were apparent with differences characterized by variations in time spent sleeping (High and Low sleepers), non-ambulatory activities (High Sitters), and ambulatory activities (Balanced Activity).
There are concerns that exposure to general anesthesia during surgery may contribute to an increased risk of Alzheimer's disease. To investigate, researchers compared exposure to general anesthesia versus regional anesthesia during elective surgery, looking for potential links to the development of dementia.
An analysis of relevant studies published to date has identified certain risk factors associated with suicidal behavior in adolescents. The analysis also revealed certain protective factors that may reduce the likelihood of suicidal behavior.
Having a strong ethnic identity was linked with a lower risk of suicidal behaviors among Black college students in a recent study published in the Journal of Multicultural Counseling and Development.
The study examined the influence of cultural orientation (ethnic identity, Afrocentric worldview, and religiosity) and personal resources (resiliency and optimism) on suicidal behaviors among Black college students.
There's considerable risk that humans transmit SARS-CoV-2, the virus that causes COVID-19, to wildlife, according to a perspective article published in Mammal Review.
The authors noted that if SARS-CoV-2 were to infect and spread among wild mammals, it could potentially cause disease in some populations, in turn further endangering already threatened species.
CLEVELAND, Ohio -- No one knows for sure how long they will live. A new study, however, suggests that leukocyte telomere length may offer some key insights into a woman's longevity and further demonstrates how maternal age at birth of last child affects telomere length and long-term health. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
