Hand-Held Device Measures Aerosols for Coronavirus Risk Assessment

Understanding aerosol concentrations and persistence in public spaces can help determine infection risks. However, measuring these concentrations is difficult, requiring specialized personnel and equipment. Now, researchers demonstrate that a commercial hand-held particle counter can be used for this purpose and help determine the impacts of risk-reducing measures, like ventilation improvements. They describe the quick and easy, portable process in the journal Physics of Fluids.

Cornell University to Extract Energy from Manure to Meet Peak Heating Demands

Cornell University is developing a system to extract energy from cattle manure to meet the campus’s peak demands for heat in the winter months. In the Journal of Renewable and Sustainable Energy, scientists involved with the project give a detailed analysis of the issues required to make this work, including scientific, economic, and energy policy considerations.

Cormac the Llama Yields Antibodies that may Prove Effective Against COVID-19 Infection

Researchers from the Uniformed Services University (USU) recently identified pint-sized antibodies, or “nanobodies,” that could protect against COVID-19. At least one of these nanobodies – produced by a llama named Cormac – also appears to work well in either liquid or aerosol form, suggesting it could also help protect a person’s lungs from infections.

Antibiotics for C-sections Effective After Umbilical Cord Clamped

Antibiotics for cesarean section births are just as effective when they’re given after the umbilical cord is clamped as before clamping – the current practice – and could benefit newborns’ developing microbiomes, according to Rutgers co-authored research. The study, by far the largest of its kind and published in the journal Antimicrobial Resistance & Infection Control, challenges current recommendations for antibiotic use. Administering antibiotics after clamping does not increase the risk of infection at the site of C-section incisions, the study concludes.

Preventing Nurse Suicides as New Study Finds Shift in Method

In a new study, University of California San Diego School of Medicine and UC San Diego Health researchers report that the rate of firearm use by female nurses who die by suicide increased between 2014 to 2017. Published December 21, 2020 in the journal Nursing Forum, the study examined more than 2,000 nurse suicides that occurred in the United States from 2003 to 2017 and found a distinct shift from using pharmacological poisoning to firearms, beginning in 2014.

Child care facilities can be safe and are essential: New Case Western Reserve study

Child care programs can be safe within the context of low community transmission of COVID-19, according to new research from Case Western Reserve University, based on data from child care programs throughout Ohio.
The study took place from Aug. 15 to Nov. 20, during a timeframe of relatively low community transmission of COVID-19. The team found COVID-19 infection rates at child care programs have been low.

Female Athletes in WNBA Don’t Return to Elite Performance for at Least 2 Years After ACL Surgery

DETROIT – With the Michigan high school and collegiate sports season influx due to the COVID-19 pandemic, a study by Sports Medicine researchers at Henry Ford Health System provides a new perspective on performance levels of female athletes after they return from anterior cruciate ligament (ACL) injury and reconstructive surgery.

Virginia Tech researchers uncover mechanisms that wire the brain’s cerebral cortex

A research team at the Fralin Biomedical Research Institute at VTC has identified the type of brain cell that produces a protein that is crucial for the formation of inhibitory circuits in the brain. This insight could one day help scientists establish the basis for developing new drugs that mature or repair cellular networks.

Infectious disease detectives: Researchers track and analyze smallpox epidemics over three centuries

Researchers from McMaster University have studied and analyzed thousands of weekly records documenting the deaths of smallpox victims in London, England over the span of nearly 300 years. The analysis provides new and rare insights into the ecology of infectious disease, establishing that the time between epidemics, the size of the outbreaks, and even the season when the epidemics occurred, changed over the centuries.

New 3D maps reveal inner workings of immune cell gene expression

The COVID-19 pandemic has highlighted how our small genetic differences can have a tremendous effect on how our bodies respond to disease. Researchers have created 3D maps of how enhancer sequences and genes interact in several types of immune cells. Their new study opens the door to understanding individual risk for diseases from asthma to cancer.

Digging Deep For Differences In Duchenne Muscular Dystrophy

DALLAS – Dec. 21, 2020 – A UT Southwestern research team has catalogued gene activity in the skeletal muscle of mice, comparing healthy animals to those carrying a genetic mutation that causes Duchene muscular dystrophy (DMD) in humans. The findings, published online recently in PNAS, could lead to new treatments for this devastating degenerative disease and insights into factors that affect muscle development.

Prostate cancer regulator plays role in COVID-19, providing a promising treatment lead

By taking a lesson from prostate cancer, researchers now have a promising lead on a treatment for COVID-19. They found that, just like in prostate cancer, TMPRSS2 is regulated by the androgen receptor in the lungs. And notably, blocking the androgen receptor led to lower expression of TMPRSS2, which led to decreased coronavirus infection in mice and cellular models.

Moffitt Researchers Discover Potential New Drug Target to Treat Cutaneous T Cell Lymphoma

In order to improve their understanding of how CTCL develops in hopes of developing new therapies, a team of Moffitt immunologists and hematologists conducted a series of studies. In an article published in The Journal of Clinical Investigation, they demonstrate that decreased expression of the protein SATB1 contributes to CTCL development and that drugs that cause SATB1 to become re-expressed may be potential treatment options for this disease.

Discovery: How Colorado Potato Beetles Beat Pesticides

New research shows that pesticide alter how Colorado potato beetles manage their DNA. These changes were passed down two generations suggesting that rapid resistance to pesticides may not require beetles to evolve their genetic code. Instead they may simply use existing genes to tolerate toxins already found in potatoes. The scientists were surprised that these epigenetic changes, triggered by a single tiny dose of pesticide, were maintained through multiple rounds of sexual reproduction.

Researchers illuminate neurotransmitter transport using X-ray crystallography and molecular simulations

Scientists from the MIPT Research Center for Molecular Mechanisms of Aging and Age-Related Diseases have joined forces with their colleagues from Jülich Research Center, Germany, and uncovered how sodium ions drive glutamate transport in the central nervous system. Glutamate is the most important excitatory neurotransmitter and is actively removed from the synaptic cleft between neurons by specialized transport proteins called excitatory amino acid transporters (EAATs)

Big step with small whirls

Skyrmions are small magnetic objects that could revolutionize the data storage industry and also enable new computer architectures. However, before they can be utilized in such applications, there are still a number of challenges that need to be overcome. A team of Empa researchers has now succeeded for the first time in producing a tunable multilayer system in which two different types of skyrmions – the future bits for “0” and “1” – can exist at room temperature, as they recently reported in the renowned journal Nature Communications.

Stroke and Altered Mental State Increase Risk of Death for COVID-19 Patients

People hospitalized with COVID-19 and neurological problems including stroke and confusion, have a higher risk of dying than other COVID-19 patients, according to a study published online today by researchers at Montefiore Health System and Albert Einstein College of Medicine in the journal Neurology®, the medical journal of the American Academy of Neurology. These findings have the potential to identify and focus treatment efforts on individuals most at risk and could decrease COVID-19 deaths.
