A Sting Operation to Save Elephants, With No Stings

It’s a familiar, dreaded scenario in many parts of Africa and Asia: An elephant shows up, wanders into farmers’ fields, and tramples and eats crops. Sometimes farmers fight back, and elephants are killed. That series of events seemed likely to play out recently when a forest elephant bull emerged from the dense jungle surrounding Gbarnjala […]

A novel combination therapy for treating vancomycin-resistant bacterial infections

Researchers have developed a novel combination therapy using the anticancer agent mitoxantrone (MTX), together with an antibiotic, vancomycin, for treating bacteria that are resistant to the vancomycin, which are also known as vancomycin-resistant Enterococcus faecalis or VRE. The therapy uniquely targets both VRE and the host, stimulating the host immune system to more effectively clear […]

Cleaner Air Helps Everyone. It Helps Black Communities a Lot.

The Environmental Protection Agency is considering new standards for the maximum amount of fine particulate matter, tiny specks about one-thirtieth the diameter of a human hair that can penetrate the lungs, in outdoor air. A recent study examined how the benefits of stricter limits would be distributed across American society. What’s new in this research […]

The Shark ‘Didn’t Look Right.’ Was It a Plastic Toy?

Goblin sharks are deep-sea fish whose frightening, protrusile jaws served as an inspiration for the terrifying creatures in the “Alien” movie franchise. Little is known about these elusive sharks, and sightings of them are extraordinarily rare. They are known to live in deep coastal waters all over the world but have never been found in […]

A Paler Uranus Emerges in the Latest Hubble Telescope Image

With the passage of the vernal equinox a few days ago, we in the Northern Hemisphere can look forward to the warmer days of spring while those in the Southern Hemisphere will begin to feel the chill of autumn. The seasons change on other planets too, none more so than Uranus, which is essentially tipped […]

Tackling counterfeit seeds with “unclonable” labels

Average crop yields in Africa are consistently far below those expected, and one significant reason is the prevalence of counterfeit seeds whose germination rates are far lower than those of the genuine ones. The World Bank estimates that as much as half of all seeds sold in some African countries are fake, which could help […]

Learning to grow machine-learning models

It’s no secret that OpenAI’s ChatGPT has some incredible capabilities — for instance, the chatbot can write poetry that resembles Shakespearean sonnets or debug code for a computer program. These abilities are made possible by the massive machine-learning model that ChatGPT is built upon. Researchers have found that when these types of models become large […]

Fiber “barcodes” can make clothing labels that last

In the United States, an estimated 15 million tons of textiles end up in landfills or are burned every year. This waste, amounting to 85 percent of the textiles produced in a year, is a growing environmental problem. In 2022, Massachusetts became the first state to enact a law banning the disposal of textiles in […]
