Children not immune to coronavirus; new study from pandemic epicenter describes severe COVID-19 response in children

Children with COVID-19 often require hospitalization and intensive care due to inflammation and respiratory issues. Researchers found that obesity and asthma were not associated with increased risk of enhanced care, but over half of the children had no known contact with a positive person.

COVID-19 puts brakes on global emissions

Global carbon dioxide emissions from fossil fuel sources reached a maximum daily decline of 17 per cent in April due to the COVID-19 pandemic. The decrease was primarily driven by a 36 per cent drop in surface transport emissions, equivalent to 7.5 megatonnes CO2.

Intent defined optical network for intelligent operation and maintenance

Researchers developed an intent-defined optical network (IDON) with artificial intelligence-based automated operation and maintenance to address the challenges of manual configuration. IDON achieves intent-oriented configuration conversion, adaptive generation and optimization strategies, and closed-loop intent-guaranteed operations, d...

Depression symptoms linked to reduced cognitive control in people with autism

A new study found that depression symptoms are associated with reduced cognitive control in individuals with autism. The researchers used a picture-word Stroop test to assess proactive control, which is the ability to plan and prepare how to direct attention. Participants with autism who had more symptoms of depression showed less abil...

Less water could sustain more Californians if we make every drop count

California cities can rely on six key strategies to provide for growing populations: conserving water through behavioral changes, reusing non-potable water for irrigation, recycling water for drinking, capturing stormwater runoff, and desalinating seawater. These measures can help reduce costs while increasing the state's water supply.

Rapid screening method targets fatty acids in yeast; Key to sustainable bioproducts

Researchers at the University of Illinois have developed a high-throughput screening tool to rapidly profile medium-chain fatty acids produced in yeast. They identified seven new genetically engineered mutants that produce higher levels of those fatty acids, which are crucial components of biodiesel and other industrial chemicals.

COVID-19 tests compared

The COVID-19 pandemic requires scalable testing technologies, but current methods vary widely, taking hours to complete and requiring extensive resources. Researchers assess various nucleic acid-based tests, highlighting the need for faster and more affordable alternatives.

Uncovering Alzheimer's disease

Researchers at the University of Missouri have found that menopause can reduce cognitive function and potentially play a role in Alzheimer's development in women. Animal studies using surgically induced menopause in rats showed poor memory and learning, indicating a decline in cognitive function.

Exposure to ultrafine aerosol particles in homes depends primarily on people themselves

A long-term study found that residents' daily activities, such as cooking and heating, significantly impact indoor ultrafine particle concentrations. The study, conducted in German apartments, showed that indoor activities account for most ultrafine particles, with outdoor air pollution playing a lesser role.

Study suggests aggressive carbon taxation could help US meet targets in Paris agreement

A new study suggests that aggressive carbon taxation in the US could help meet its Paris Agreement targets by reducing greenhouse gas emissions. The research found that only limited opportunities for decarbonization exist outside of the electricity sector, but significant revenue can be generated from carbon taxes.

Nature unveiling herself before science

Scientists have developed a new prototype that amplifies signals up to 10,000-fold, enabling the monitoring of rapid chemical processes on the milliseconds timescale. This breakthrough allows for the analytical characterization of pre-nucleation species in biomineralization, challenging current theoretical frameworks.
