Immune System Affects Mind and Body, Study Indicates

Source: Washington University School of Medicine

New research at Washington University School of Medicine in St. Louis helps illuminate a surprising mind-body connection. In mice, the researchers found that immune cells surrounding the brain produce a molecule that is then absorbed by neurons in the brain, where it appears to be necessary for normal behavior.

New Treatments for Deadly Lung Disease Could Be Revealed By 3D Modeling

Source: University of Michigan

Research shows why pulmonary fibrosis drugs that target lung stiffness alone may not work in patients, even if they show promise in a Petri dish. A 3D bioengineered model of lung tissue built by University of Michigan researchers is poking holes in decades worth of flat, Petri dish observations into how the deadly disease pulmonary fibrosis progresses.

Asthma Patients Given Risky Levels of Steroid Tablets

Source: University of Queensland

More than one quarter of asthma patients have been prescribed potentially dangerous amounts of steroid tablets, with researchers warning this puts them at greater risk of serious side-effects. Researchers analysed data from the Pharmaceutical Benefits Scheme (PBS) to find out how often Australians with asthma were taking repeated courses of steroid tablets.

Study Links Skin Lightening Products with Altered Steroid Hormone Levels

Source: TimesNow News

Women that frequently used high strength steroid creams had significantly lower baseline cortisol levels, a sign of impaired cortisol function. Women who misuse corticosteroid creams for cosmetic skin lightening may be at risk of developing adrenal insufficiency, according to new research. The research was presented at e-ECE 2020.

Researchers Identify Key Role of Immune Cells in Brain Infection

Source: University of Liverpool

A new study has detailed the damaging role played by the immune system in a severe brain condition most commonly caused by the cold sore virus. Researchers have identified the specific type of immune cell that induces brain inflammation in herpes simplex virus (HSV) encephalitis. Crucially, they have also determined the signalling protein that calls this immune cell into the brain from the bloodstream.

New Research Finds People React Better to Both Negative and Positive Events with More Sleep

Source: University of British Columbia

New research from UBC finds that after a night of shorter sleep, people react more emotionally to stressful events the next day—and they don’t find as much joy in the good things. The study, led by health psychologist Nancy Sin, looks at how sleep affects our reaction to both stressful and positive events in daily life.

Reprogramming Brain Cells Enables Flexible Decision-Making

Source: University of Zurich

Humans, like other animals, have the ability to constantly adapt to new situations. Researchers at the Brain Research Institute of the University of Zurich have utilized a mouse model to reveal which neurons in the brain are in command in guiding adaptive behavior. Their new study contributes to our understanding of decision-making processes in healthy and infirm people.

“COVID-19 Is Here to Stay for The Foreseeable Future”

Source: Max Planck Institute for the Science of Human History

In a recent paper, a group of multidisciplinary authors discuss the future of field-based sciences in a COVID-19 world. The piece outlines the epidemiological characteristics of SARS-CoV-2, the virus causing the COVID-19 pandemic, details its effects on field-based sciences and identifies how working practices can be remodelled to overcome the challenges brought on by the virus.

Smoking Linked to Bleeding in The Brain in Large, Long-Term Study of Twins

Source: American Heart Association

Researchers in Finland found a link between smoking and subarachnoid hemorrhage (SAH), a type of bleeding stroke, in a study of more than 16,000 pairs of twins over 42 years. The study found that bleeding in the brain can be explained to a greater degree by environmental risk factors, such as smoking, than by genetic influence.
