While other medical systems across the country failed to maintain HIV screening volumes throughout the COVID-19 pandemic, the University of Chicago Medicine maintained screening volumes by including universal HIV screening alongside COVID-19 testing in its busy emergency department, according to a new report published April 12 in JAMA Internal Medicine.

May 6, 2021 -- A significant level of symptoms of depression, anxiety and post-traumatic stress may follow COVID-19 independent of any previous psychiatric diagnoses, according to new research by Columbia University Mailman School of Public Health with colleagues at Universidade Municipal de São Caetano do Sul in Brazil. Exposure to increased symptomatic levels of COVID-19 may be associated with psychiatric symptoms after the acute phase of the disease.

Quantum computers or quantum sensors consist of materials that are completely different to their classic predecessors. These materials are faced with the challenge of combining contradicting properties that quantum technologies entail, as for example good accessibility of quantum bits with maximum shielding from environmental influences. In this regard, so-called two-dimensional materials, which only consist of a single layer of atoms, are particularly promising.

The Marburg virus, a relative of the Ebola virus, causes a serious, often-fatal hemorrhagic fever. Transmitted by the African fruit bat and by direct human-to-human contact, Marburg virus disease currently has no approved vaccine or antivirals to prevent or treat it.

When you save an image to your smartphone, those data are written onto tiny transistors that are electrically switched on or off in a pattern of "bits" to represent and encode that image. Most transistors today are made from silicon, an element that scientists have managed to switch at ever-smaller scales, enabling billions of bits, and therefore large libraries of images and other files, to be packed onto a single memory chip.

Just as people keep their houses clean and clutter under control, a crew of cells in the body is in charge of clearing the waste the body generates, including dying cells. The housekeeping cells remove unwanted material by a process called phagocytosis, which literally means 'eating cells.' The housekeepers engulf and ingest the dying cells and break them down to effectively eliminate them.

MUSC Hollings Cancer Center researchers added to the understanding of the protective immune response against the SARS-CoV-2 virus in a study published in April in iScience. The team found that approximately 3% of the population is asymptomatic, which means that their bodies can get rid of the virus without developing signs of illness.

The researchers screened more than 60,000 blood samples from symptomless individuals in the Southeastern U.S., including Georgia, South Carolina and North Carolina, for the IgG antibody to the viral spike protein.

HOUSTON - (May 6, 2021) - A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications.

Laser-induced graphene (LIG), introduced in 2014 by Rice chemist James Tour, involves burning away everything that isn't carbon from polymers or other materials, leaving the carbon atoms to reconfigure themselves into films of characteristic hexagonal graphene.

The introduction of lithium-ion (Li-ion) batteries has revolutionized technology as a whole, leading to major advances in consumer goods across nearly all sectors. Battery-powered devices have become ubiquitous across the world. While the availability of technology is generally a good thing, the rapid growth has led directly to several key ethical and environmental issues surrounding the use of Li-ion batteries.

Early on in the COVID-19 pandemic, health officials seized on contact tracing as the most effective way to anticipate the virus's migration from the initial, densely populated hot spots and try to curb its spread. Months later, infections were nonetheless recorded in similar patterns in nearly every region of the country, both urban and rural.

As state and federal authorities decide whether to continue reimbursing for telehealth services that were suddenly adopted last spring in response to the coronavirus pandemic, a new study out of UC San Francisco has found that clinicians in the San Francisco Health Network (SFHN) overwhelmingly support using these services for outpatient primary care and specialty care visits.

Computer science researchers at the University of Central Florida have developed a sarcasm detector.

Social media has become a dominant form of communication for individuals, and for companies looking to market and sell their products and services. Properly understanding and responding to customer feedback on Twitter, Facebook and other social media platforms is critical for success, but it is incredibly labor intensive.

Even the humble fruit fly craves a dose of the happy hormone, according to a new study from the University of Sussex which shows how they may use dopamine to learn in a similar manner to humans.

Informatics experts at the University of Sussex have developed a new computational model that demonstrates a long sought after link between insect and mammalian learning, as detailed in a new paper published today in Nature Communications.

To observe the swift neuronal signals in a fish brain, scientists have started to use a technique called light-field microscopy, which makes it possible to image such fast biological processes in 3D. But the images are often lacking in quality, and it takes hours or days for massive amounts of data to be converted into 3D volumes and movies.

INDIANAPOLIS - As electronic medical records (EMRs) are increasingly used across the United States, the next generation of physicians, nurses, social workers, pharmacists and other clinicians need to acquire new knowledge and competencies related to use of EMRs early in their clinical education. But training is not routinely provided.
