A study has identified several new forms of mosquito immune cells and could shed light on the insect immune system and how mosquitoes transmit parasites that cause malaria.

The United States has minimal regulations around the harvest and sale of wild fungi. Food products that tout “wild mushrooms” as ingredients are often vague and non-specific, making it impossible to know if the products are truly wild or just cultivated varieties Researchers used DNA barcoding techniques to test what mushroom species made up 16 food products that listed “wild mushrooms” on their labels.

Skoltech researchers and their colleagues from Russia, Germany and the US have found Prozac to reduce lipid concentrations in juvenile macaques who received the antidepressant for two years, compared to a control group of untreated animals.

Scientists have developed novel gas sensors with improved detection, sensitivity and durability by combining organic and inorganic materials.

Wastewater analysis has shown that some people turned to a variety of drugs for relief during the pandemic restrictions. A spike in consumption of easily abused prescription opioids and anti-anxiety sedatives was identified, while some illicit drug use plummeted, between March and June 2020.

The highest-ever resolution imaging of an infectious prion provides the first atomic-level data of how these abnormal proteins are assembled to cause fatal neurodegenerative diseases in people and animals—and how they can be potentially targeted by new therapies.

Many people are now open to trying plant-based alternatives, as long as they closely resemble the taste, odor, appearance and texture of real beef. Now, researchers report that the aromas of a couple of plant-based burgers come close to the real deal when they are cooking.

The same phenomenon that causes aurorae, the curtains of light often visible from polar regions of Earth, causes ozone layer depletion. This could have significance for global climate change and therefore, understanding this phenomenon is important. Now, a group of scientists has provided greater insight into this phenomenon.

Many products that require strength, durability and weather resistance are made with a type of nylon called nylon 6-6. However, producing this material requires an environmentally unfriendly process, which uses the endangered element zinc as a catalyst. Now, researchers have developed “greener” methods that use alternative metals. They might even be able to substitute waste iron in the form of rust, or ferric oxide, for the endangered element.

A team of researchers at University of California San Diego School of Medicine detail how GIV/Girdin, a ubiquitous signaling molecule plays a critical role in male fertility.
