COVID-19 - The virus and the vasculature
A new international study, led by the University of Leeds, warns that even with some lockdown measures staying in place to the end of 2021, without more structural interventions global temperatures will only be roughly 0.01Â°C lower than expected by 2030. However, the study estimates that including climate policy measures as part of an economic recovery plan with strong green stimulus could...
COVID-19 crisis exposes imbalance in EU state aid for aviation sector
In severe cases of COVID-19, the infection can lead to obstruction of the blood vessels in the lung, heart and kidneys. Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have now shown that activated immune cells and blood platelets play a major role in these pathologies.
COVID-19 may have a longer incubation period, suggests probability analysis of Wuhan cases
Dr Steven Truxal, an aviation law expert in The City Law School, says state aid offered to airlines in response to the current crisis raises questions around unfair competition between European carriers and may be the subject of future challenge by carriers outside the EU.
Decline in plant breeding programs could impact food security
By applying the renewal theory in probability to reduce recall bias in initial case reports, scientists have come up with a new estimate for the incubation period of COVID-19. Their mean estimate of 7.76 days.
Deep-sea misconceptions cause underestimation of seabed-mining impacts
A team of scientists led by Kate Evans, a Washington State University horticulture professor who leads WSU's pome fruit (apples and pears) breeding program, found that public plant breeding programs are seeing decreases in funding and personnel.
Does physician burnout, depression, career satisfaction differ by race/ethnicity?
A new publication on the impacts of deep-seabed mining by 13 prominent deep-sea biologists, led by University of Hawai'i at Mānoa, seeks to dispel scientific misconceptions that have led to miscalculations of the likely effects of commercial operations to extract minerals from the seabed.
Epirubicin-loaded nanomedicines beat immune checkpoint blockade resistance in glioblastoma
This survey study of US physicians examined whether there were differences by race/ethnicity in burnout, symptoms of depression, career satisfaction and work-life balance.
Experts urge evaluation of diet at routine check-ups
A nanomedicine-based strategy for chemo-immunotherapy (CIT) of glioblastoma (GBM), which has the worst prognosis among brain tumors, was successfully developed.
Florida current is weaker now than at any point in the past century
Unhealthy dietary patterns are a leading cause of heart disease and stroke as well as other chronic diseases.Clinician-delivered diet counseling can improve diet behaviors and heart disease risk factors.Quick, simple dietary assessment tools can be a part of routine office visits and integrated into electronic health records for follow-up.
Genetic cause of congenital malformation discovered
A key component of the Gulf Stream has markedly slowed over the past century--that's the conclusion of a new research paper in Nature Communications published on August 7, 2020.
Heart attack case rates, treatment approaches, outcomes during COVID-19 pandemic
Spontaneous mutations of a single gene are likely to cause serious developmental disorders of the excretory organs and genitalia. This is shown in an international study led by the University of Bonn and published in the journal "Frontiers in Cell and Developmental Biology". The researchers also owe their findings to an unusual model organism: the zebrafish.
Heavier smoking linked to skyrocketing health risks
The increases and decreases in patient volume and associated changes in treatment experienced by individuals presenting with acute heart attack (myocardial infarction) before and immediately after the onset of the COVID-19 pandemic are examined in this observational study.
Highly sensitive dopamine detector uses 2D materials

Huge ring-like structure on Ganymede's surface may have been caused by violent impact
Taking advantage of a total lunar eclipse, astronomers using the NASA/ESA Hubble Space Telescope have detected ozone in Earth's atmosphere. This method serves as a proxy for how they will observe Earth-like planets around other stars in the search for life. This is the first time a total lunar eclipse was captured from a space telescope and the first time such an eclipse has been studied in...
Inexpensive, accessible device provides visual proof that masks block droplets
Image data reanalysis by researchers from Kobe University and the National Institute of Technology, Oshima College have revealed that ancient tectonic troughs are concentrically distributed across almost the entire surface of Ganymede. Computer simulation results suggest that this giant crater could have resulted from the impact of an asteroid with a 150km radius. If so, this the largest impact...
