Gentler, safer hair dye based on synthetic melanin

Researchers at Northwestern University developed a new hair dye process using synthetic melanin that mimics natural human hair pigmentation. The dye, tested under mild conditions, produces natural-looking colors that persist for at least 18 washes, avoiding toxicity and allergies associated with traditional hair dyes.

Telemedicine transforms response to COVID-19 pandemic in disease epicenter

A study by NYU Langone Health shows a massive expansion of telemedicine during the COVID-19 pandemic, with virtual urgent care visits growing by 683% and non-urgent virtual care visits increasing by 4,345%. The rapid growth was made possible by US insurers expanding coverage and state licensing relaxations.

A census of star brightness: The sun is less active and variable than similar stars

Researchers analyzed 369 solar-like stars and found that the Sun is less magnetically active and variable than similar stars. The study suggests that most stars are five times more variable than the Sun over the last 140 years, with potential explanations including long-term variability or unrecognized differences.

Cardiovascular impairment in COVID-19

Researchers recommend using cardiovascular anti-inflammatory therapies to treat COVID-19 patients with severe cardiovascular problems, citing potential risks with current treatments. The study provides guidance for clinicians on selecting specific therapies depending on disease severity and patient response.

Investors punish for social irresponsibility depending on proportion of company execs with law degrees

Research from the University of Notre Dame suggests that investors react more severely to corporate social irresponsibility (CSI) when top management executives have a higher proportion of law degrees. Firms with an average proportion of law-trained executives among their leadership teams tend to receive less punishment, while those wi...

Data from 2 space lasers comprehensively estimate polar ice loss and sea level rise

A new analysis of data from NASA's ICESat-2 and ICESat satellites estimates that polar ice losses from Greenland and Antarctica contributed to 14mm of sea level rise between 2003 and 2019. The study projects that melting ice from these regions will increasingly contribute to sea level rise within tens to hundreds of years.

COVID-19 news from Annals of Internal Medicine

Two new articles from Annals of Internal Medicine explore the availability of telemedicine services and pandemic surge modeling for COVID-19. A cross-sectional study found that many US hospitals lack existing telemedicine programs, while a podcast discussion highlights the importance of rapid investment in remote care infrastructure.
