COVID-19 testing and reporting needs improving in United States prisons

Researchers at the University of North Carolina at Chapel Hill and Cornell University have conducted a study showing that many states across the US are not reporting fully on the number of people being tested for coronavirus disease 2019 (COVID-19) in prisons, with some also not reporting on cases of fatalities.

Promising new candidate 'virus-like particle' vaccine for COVID-19

Researchers in the UK and Taiwan have demonstrated the potential of a new candidate vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the virus responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

BCG vaccine offers protection for elderly people against respiratory infections

The BCG vaccine has a broad, stimulating effect on the immune system. This gives it an effective preventive action against various infections - possibly also against COVID-19. New studies are investigating that.

Blood microRNA biomarker may have potential to detect head and neck cancer

Researchers at Flinders University are expanding work on a promising blood test model to help predict or diagnose head and neck cancer, a difficult cancer to pick up early and treat.

Cancer cells reshape, destroy or integrate into blood vessels to spread

In laboratory studies, Johns Hopkins Kimmel Cancer Center and Johns Hopkins University researchers observed a key step in how cancer cells may spread from a primary tumor to a distant site within the body, a process known as metastasis.

Growth hormone associated with early puberty and future breast cancer risk

When girls reach puberty at an unusually early age, they face a significantly higher risk of developing breast cancer later in life. Now, experts at Cincinnati Children's and the University of Cincinnati offer a new, unified explanation for why that increased risk occurs.

Study offers hope for Norwegians suffering from chronic sleep disorders

Approximately 500 000 Norwegians suffer from chronic sleep disorders, also called insomnia. Researchers have long known that cognitive behavioural therapy for insomnia is the best documented treatment, but few people have access to such therapy.

Researchers identify a new way to curb air pollution

Studies show those flashing real-time speed limit displays you see in neighborhoods are effective at telling motorists to slow down. Kerry Kelly thought: Could something like that help curb air pollution?

Brain estrogen critical for astrocyte activation and neuroprotection

When the brain isn't getting enough oxygen, estrogen produced by neurons in both males and females hyperactivates another brain cell type called astrocytes to step up their usual support and protect brain function.

Silicon nitride shows potent SARS-CoV-2 neutralization capability

A new study published on the preprint server bioRxiv* in August 2020 shows that the man-made compound silicon nitride, which is used in medical implants and high mechanical performance engineering applications, is capable of inactivating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at varying concentrations without causing cell cytotoxicity. This finding should be investigated to develop disinfectants to clear the virus from surfaces, preventing its spread.

Human antibody response to SARS-CoV-2

A new study published on the preprint server medRxiv* in August 2020 reports on the human antibody response in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which is key to developing vaccines and managing the pandemic, as well as designing and executing serologic testing and interpreting their results.

Warnings can protect memory from misleading information

Warning witnesses about the threat of misinformation - before or after an event - significantly reduces the negative impact of misinformation on memory, according to new research performed at Tufts University.

Low dose colchicine significantly reduces risk of cardiovascular death

An Australian-Dutch trial led by Perth GenesisCare cardiologists, Professor Peter Thompson and Dr Mark Nidorf, in collaboration with the Dutch Network for Cardiovascular Research (WCN) in the Netherlands, confirmed that low dose colchicine was safe, well-tolerated over the long-term, and significantly reduced the risk of cardiovascular death, heart attack, and ischemic stroke in patients with chronic coronary disease.

Patients with cancer and COVID-19 infection can experience blood clots

UC researchers and physicians are learning that COVID-19 impacts more than just the lungs. The list of potential issues multiplies when doctors also consider its impact on patients with other underlying conditions or the medications used to treat those conditions.

Spike ferritin nanoparticles show potential as SARS-CoV-2 vaccine

Now, a new study published on the preprint server bioRxiv* in August 2020 reports the induction of neutralizing antibodies in mice by a single dose of a ferritin nanoparticle-based vaccine containing the spike protein.

Diminished biological arousal before global pandemic may predict PTSD symptoms

People who did not have a large heart rate response to a stress task surprised researchers later -- after the onset of the COVID-19 pandemic -- when they showed more symptoms of post-traumatic stress disorder related to the crisis than others who also did the stress task and COVID-19 stress ratings.
