Research indicates that while the most severe effects of SARS-CoV-2 were observed in patients with acute COVID-19, individuals who experienced milder cases and were not hospitalized also reported symptoms of memory loss and attention deficits lasting over 18 months post-infection. Memory loss and attention deficit are common complaints among severe COVID-19 survivors. However, these and other cognitive [...]
Vanderbilt researchers have developed a set of nanoparticles that stimulate the immune system in mice to fight cancer and may eventually do the same in humans. The research, led by John T. Wilson, associate professor of chemical and biomolecular engineering and biomedical engineering, was recently published in ACS Nano. Working with collaborators at Yale University, Wilson and his [...]
The need for innovative antimicrobial agents has become increasingly urgent due to the rise of antibiotic-resistant pathogens and the persistent threat of infections acquired during hospital stays. Traditional antibiotics and antiseptics are often ineffective against these resilient microorganisms, leading to severe health complications and increased healthcare costs. Therefore, researchers are exploring alternative solutions that [...]
Research reveals that selective expression of maternal or paternal X chromosomes varies by organ, driven by cellular competition. A new study published today (July 26) in Nature Genetics by the Lymphoid Development Group at the MRC Laboratory of Medical Sciences has revealed that the contribution of cells expressing maternal or paternal X chromosomes can be selectively [...]
Whether or not a person becomes seriously ill with COVID-19 depends, among other things, on genetic factors. With this in mind, researchers from the University Hospital Bonn (UKB) and the University of Bonn, in cooperation with other research teams from Germany, the Netherlands, Spain and Italy, investigated a particularly large group of affected individuals. [...]
Sleep and wake: They're totally distinct states of being that define the boundaries of our daily lives. For years, scientists have measured the difference between these instinctual brain processes by observing brain waves, with sleep characteristically defined by slow, long-lasting waves measured in tenths of seconds that travel across the whole organ. For the [...]
The study broadly reveals how fast brain waves, previously overlooked, establish fundamental patterns of sleep and wakefulness. Scientists have developed a new method to analyze sleep and wake states by detecting ultra-fast neuronal activity patterns, just milliseconds long, challenging traditional understandings based on slower brain waves. This research also uncovered that individual brain regions [...]
Researchers have found that different facial temperatures correlate with chronic illnesses like diabetes and high blood pressure, and these can be detected using AI with thermal cameras. They highlight the potential of this technology for promoting healthy aging by using thermal facial imaging to predict a person’s health status and biological age. The study [...]
In a recent study published in the journal Nature, a team of researchers used murine models and various pharmacological and genetic approaches to examine whether pro-inflammatory signaling involving interleukin (IL)-11, which activates signaling molecules such as extracellular signal-regulated kinase (ERK) and mammalian target of rapamycin complex 1 (mTORC1), was negatively associated with health- and lifespan. [...]
New research led by Oregon Health & Science University reveals a promising approach to developing a universal influenza vaccine—a so-called "one and done" vaccine that confers lifetime immunity against an evolving virus. The study, published today in the journal Nature Communications, tested an OHSU-developed vaccine platform against the virus considered most likely to trigger the [...]
