A horizon-scan of chemical pollution research needs in has Antarctica has called for Antarctic Treaty consultative parties to extend their national chemical monitoring programs to their Antarctic research stations and Territories.
Title 42, the United States pandemic rule that had been used to immediately deport hundreds of thousands of migrants who crossed the border illegally over the last three years, has expired. Those migrants will have the opportunity to apply for asylum. President Biden's new rules to replace Title 42 are facing legal challenges. Border crossings have already risen sharply, as many migrants attempt to cross before the measure expires on Thursday night. Some have said they worry about tighter controls and uncertainty ahead. Immigration is once again a major focus of the media as we examine the humanitarian, political, and public health issues migrants must go through.
As the northern hemisphere heads into summer, we may be in for a COVID-19 reprieve. Not because the pandemic is over; the Omicron subvariant ‘Arcturus’ is still creeping upward and causing new symptoms. But two new studies from the University of Illinois add evidence supporting a seasonal pattern in the behavior of the SARS-CoV-2 virus.

At the 184th ASA Meeting, Colin Malloy of Ocean Network Canada will present his method to transform ocean data into captivating, solo percussion songs. He employs sound from hydrophones and introduces elements inspired by ocean-related data such as temperature, acidity, and oxygenation. For example, in his piece, Oil & Water, Malloy represents the impact of oil production on the oceans. He plays an eerily catchy melody on steel drums and inserts noise to represent oil production over the past 120 years.
Air pollution has been shown to have a negative effect on the prognosis of ischemic stroke, or stroke caused by reduced blood flow to the brain, but the exact mechanism is unknown. A team of researchers recently conducted a study to determine whether or not increased inflammation of the brain, also known as neuroinflammation, is the main culprit.
Our industrialized society releases many and various pollutants into the world. Combustion in particular produces aerosol mass including black carbon. Although this only accounts for a few percent of aerosol particles, black carbon is especially problematic due to its ability to absorb heat and impede the heat reflection capabilities of surfaces such as snow.
Finding, cultivating, and bioengineering organisms that can digest plastic not only aids in the removal of pollution, but is now also big business.

The air pollutant secondary organic aerosol (SOA) forms when ammonia and amines react with oxygenated species. When ammonia is present when alkenes react with ozone, SOA increases in size and numbers. This may be due to Criegee intermediates. New research found that a particular amine, dimethylamine, reacts 34,000 times faster with one version of the Criegee intermediate acetaldehyde oxide than with another version of the same compound.
After capturing the world’s attention on expeditions around East Africa, the Flipflopi project continues to find ways to inspire communities, governments and businesses to take action against environmental pollution.

The researchers focused on 66 PFAS compounds for their study. These can be grouped into three categories: 1) PFAS groups that have been regulated for some time; 2) new PFAS that industry uses as substitutes for regulated PFAS; and 3) precursors that can degrade to other, more persistent PFAS.
Biocides can harm the environment and hinder the work of wastewater treatment facilities. Besides this, toxic biocides can make waste unsuitable for further use as biofertilizers and biofuel production. The Russian scientists proposed the solution to this problem
99% of the world's population breathes air that exceeds the limits recommended by the World Health Organization (WHO). This scenario is exacerbated in urban areas where more than 50% of the world's population is concentrated.
While paper packaging is often seen as the sustainable, environmentally friendly alternative to plastic, new research by Aradhna Krishna has revealed that excess paper packaging often creates the illusion of sustainability without actually reducing plastic waste.
In Biointerphases, researchers develop a fabrication method to increase the efficacy and longevity of membrane separation technology. The team created a nanofibrous membrane with electrospinning, in which a liquid polymer droplet is electrified and stretched to make fibers, and increased the roughness of the membrane surface by loading it with silver nanoparticles. In water, this rough surface promotes a stable layer of water, which acts as a barrier to prevent oil droplets from entering the membrane. The technology is greater than 99% effective at separating a petroleum ether-in-water emulsion.
As Corn Belt states seek ways to curb nitrogen flow from farms into the Gulf of Mexico, new University of Illinois research adds evidence for winter cover crops as an important part of the solution.
