Using real neural networks to pinpoint the start of brain disease

When the symptoms of neurodegenerative diseases like Parkinson's become clear enough to make a diagnosis, there have already been significant changes in a person's brain. That's why researchers believe that finding a way to identify this turning point could be the key to better treatments.

First global statistical analysis of harmful algal blooms

The first-ever global statistical analysis of trends in harmful algal blooms (HABs) has shown that, worldwide, there is no significant increase in HABs events, but that in some regions, events that include toxic species of algae affecting humans and wildlife are on the rise. In addition, the study finds that human activity, primarily aquaculture in coastal waters, and the economic impacts that HABs event cause to the fast-growing growing industry, is likely behind the perceived increase.

Are LGBT high school students more likely to use illicit substances?

It's not easy being a teenager. Teens have to cope with the often chaotic onset of physical, psychological and emotional changes. For teens in high school, there's the added pressure to perform academically. LGB (lesbian, gay, bisexual) high school students face additional stress factors, including stigma and discrimination due to their sexual orientation and gender identity.

Why Indigenous knowledge should be an essential part of how we govern the world's oceans

,Our moana (ocean) is in a state of unprecedented ecological crisis. Multiple, cumulative impacts include pollution, sedimentation, overfishing, drilling and climate change. All affect the health of both marine life and coastal communities.

Foxconn subsidiary hit as Taiwan virus cluster grows

A subsidiary of Taiwan's tech giant Foxconn said Tuesday it has temporarily suspended operations after six foreign workers tested positive for COVID-19 in the latest outbreak within the industry.

Scientists can predict which women will have serious pregnancy complications

Women who will develop potentially life-threatening disorders during pregnancy can be identified early when hormone levels in the placenta are tested, a new study has shown.

Experiments show natural selection opposes sexual selection

Natural selection can reverse evolution that occurs through sexual selection and this can lead to better females, new research shows.

How COVID-19 wreaks havoc on human lungs

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have published the first detailed atomic-level model of the SARS-CoV-2 "envelope" protein bound to a human protein essential for maintaining the lining of the lungs. The model showing how the two proteins interact, just published in the journal Nature Communications, helps explain how the virus could cause extensive lung damage and escape the lungs to infect other organs in especially vulnerable COVID-19 patients. The findings may speed the search for drugs to block the most severe effects of the disease.

Projected acidification of the Great Barrier Reef could be offset by ten years

New research has shown that by injecting an alkalinizing agent into the ocean along the length of the Great Barrier Reef, it would be possible, at the present rate of anthropogenic carbon emissions, to offset ten years' worth of ocean acidification.

E-scooter injuries most likely at weekends and after alcohol-fueled risk-taking

E-scooter injuries are most likely to occur at the weekend and after alcohol-fuelled risk taking, such as kerb jumping, reveals an analysis of the pattern and timing of these injuries in one European city, and published online in Emergency Medicine Journal.

Plant-based and/or fish diets may help lessen severity of COVID-19 infection

Plant-based and/or fish (pescatarian) diets may help lower the odds of developing moderate to severe COVID-19 infection, suggest the findings of a six-country study, published in the online journal BMJ Nutrition Prevention & Health.

Brazil braces for third wave of COVID-19

Already reeling from one of the highest death tolls in the pandemic, Brazil is bracing for the threat of a third wave of COVID-19, fueled by vaccination delays and a lack of containment measures.

Kids 5 and up get shots in tests for COVID vaccine

Seven-year-old Russell Bright squeezed his dad's hand tightly as tests of Pfizer's COVID-19 vaccine started Monday in Louisiana for children ages 5 through 11.

Down Under criminals tricked into using FBI-run message app

Authorities in Australia and New Zealand said Tuesday they've dealt a huge blow to organized crime after hundreds of criminals were tricked into using a messaging app that was being secretly run by the FBI.

Super productive 3D bioprinter could help speed up drug development

A 3-D printer that rapidly produces large batches of custom biological tissues could help make drug development faster and less costly. Nanoengineers at the University of California San Diego developed the high-throughput bioprinting technology, which 3-D prints with record speed—it can produce a 96-well array of living human tissue samples within 30 minutes. Having the ability to rapidly produce such samples could accelerate high-throughput preclinical drug screening and disease modeling, the researchers said.

Consumers spent less on candy and desserts when shopping online

When shopping online, participants surveyed spent more money, purchased more items, and spent less on candy and desserts than when they shopped in-store, according to a new study in the Journal of Nutrition Education and Behavior.

Orphans and exiles: Research shows the impact of family separation

New research from Binghamton University, State University of New York shows the human trauma and family separation that resulted from the Trump Administration's zero tolerance policy on undocumented immigration.

A new disease called halo blight threatens Michigan hop production

If you're a beer drinker, you've noticed that hoppy beers have become increasingly popular. Most of the nation's hops come from the Pacific Northwest. However, commercial hop production regions have expanded significantly. In Michigan hop production nearly tripled between 2014 and 2017 and in 2019, Michigan growers harvested around 720 acres of hops.

A new global study of 30-day outcomes in children and adolescents with COVID-19 found that while death was uncommon, the illness produced more symptoms and complications than seasonal influenza.

Modeling study suggests that schools can safely reopen with proper mitigation strategies

A modeling study found that with controlled community transmission and moderate mitigation strategies in place, schools can reopen safely. Asymptomatic screening is one mitigation strategy identified that could facilitate reopening at higher local incidence while minimizing transmission risk. The findings are published in Annals of Internal Medicine.
