Vitamin D3 supplementation shows no therapeutic benefits in severe COVID-19 patients, study finds

A team of researchers at the University of São Paulo in Brazil aimed to determine if vitamin D3 supplementation reduces the length of stay in hospitalized patients with severe COVID-19.

Around 10 SARS-CoV-2 virions per cell in human body, study finds

A new study has found that there are about ten virus particles in each cell in the body. The research team from the Weizmann Institute of Science in Israel and the University of California in the USA estimate that each infected person carries around 109-1011 virions during peak infection.

Ancient East Asian peoples may have adapted to coronavirus-like epidemic up to 25,000 years ago

A new study by researchers at the University of Adelaide and Australian National University in Australia and the University of Arizona in the US shows that an ancient coronavirus-like epidemic drove the adaptation of East Asian peoples from 25,000 to 5,000 years ago.

How weather affects SARS-CoV-2 transmission: A US-based case study

How changes in the weather affect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the topic of several studies. The preoccupation of researchers with this aspect of the coronavirus disease 2019 (COVID-19) pandemic follows from observations that the flu virus and other coronaviruses follow seasonal patterns. Understanding how SARS-CoV-2’s transmissibility is affected by seasonal changes can thus help us to develop more informed preventative measures against its spread.

CRYM protein counteracts the growth of prostate tumors

Prostate cancer is caused by elevated hormone levels, and tumors are generally treated using hormone therapy. However, after some time, tumor growth is no longer dependent on hormones, which results in resistance to treatment. As a result, new types of treatments are urgently needed.

Study sheds new light on how diabetes contributes to the development of Alzheimer’s disease

New research from the University of Eastern Finland explores the role of diabetes in the cellular and molecular changes underlying Alzheimer's disease.

Around 30 percent of Australians hesitant to accept SARS-CoV-2 vaccine, study finds

A new study published on the preprint server medRxiv* in November 2020 suggests that a significant proportion of the Australian population is likely to show vaccine hesitancy. This indicates the need for public health messaging as well as, in some cases, other policy measures.

COVID-19 during pregnancy can cause placental inflammation and impaired immunity

A new study conducted by a team of researchers at Johns Hopkins University, USA, has observed how pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) show stunted antiviral immune responses.

Severe COVID-19 complications linked to gut barrier breakdown

A new study claims that severe COVID-19 is caused by a positive feedback loop triggered by systemic inflammation and mediated by abnormal gut permeability. This finding could potentially help open up new avenues of treatment.

Neuronal population dynamics in the motor cortex are different for reach and grasp behaviors

A new study from researchers at the University of Chicago has found that neuronal population dynamics in the motor cortex are very different during reaching and grasping behavior, challenging a popular theory that indicated intrinsic, dynamic patterns control motor behaviors.

Study compares neural activity to understand language comprehension in adults

Learning a language later in life changes how the two halves of the brain contribute. As skills improve, language comprehension changes hemisphere specialization, but production does not, according to new research published in JNeurosci.

Cannabidiol oils are equally or less effective at inhibiting certain cancer cell lines

Cannabidiol (CBD) oils are equally or less effective at inhibiting the growth of certain cancer cells compared to pure CBD, according to Penn State College of Medicine researchers.

Immunological memory can protect people against new infection after COVID-19 recovery

Until now, it was unclear whether a survived SARS-CoV-2 infection or COVID-19 leads to persistent immunological memory and thus can protect against a new infection.

Fatal chain reaction in Alzheimer's disease starts much earlier than commonly assumed

Alzheimer's disease develops over decades. It begins with a fatal chain reaction in which masses of misfolded beta-amyloid proteins are produced that in the end literally flood the brain.

Study demonstrates 24-hour rat liver viability in a normothermic machine perfusion system

In a paper published in TECHNOLOGY, a team of researchers from Massachusetts General Hospital (MGH) has demonstrated 24-hour rat liver viability in a normothermic machine perfusion (NMP) system.

LOX plays a number of key roles in promoting skin and organ fibrosis in scleroderma

A team of researchers at the Medical University of South Carolina (MUSC) has found that the molecule lysyl oxidase (LOX) plays a number of important roles in promoting skin and organ fibrosis in scleroderma, a connective tissue disorder.

UCLA researchers pinpoint how smoking causes more severe COVID-19 infection

UCLA researchers using a model of airway tissue created from human stem cells have pinpointed how smoking cigarettes causes more severe infection by SARS-CoV-2, the virus that causes COVID-19, in the airways of the lungs.
