Race, age and gender associated with experiences of harassment among gig workers‎

The gig economy is rapidly growing, and scholars are still working to understand the conditions gig workers encounter. Julieta Aguilar at the University of Kentucky, U.S., and Dr. Jeremy Reynolds at Purdue University, U.S., examined experiences of harassment in the gig economy. Their study, published on Nov. 4, 2026, in the journal PLOS One, found associations between race, gender, age and reported experiences of harassment, indicating that already precarious employment may be even more fraught for some workers.

Some cats are shy, just like human infants‎

Some cats display a complex mixture of fear and curiosity, which is similar to shyness observed in human infants, according to a study published Nov. 4, 2026, in the journal PLOS One by Madoka Hattori at Kyoto University, Japan, and colleagues.

Big extended families help adult female ground squirrels survive hibernation‎

For Belding's ground squirrels, adult females are more likely to survive from year to year if they live near more adult female kin—but neither males nor young females get the same boost from nearby family. Jill Mateo and colleagues at the University of Chicago, U.S., report these findings on Nov. 4, 2026, in the journal PLOS One.

A 7,000-year-old piece of leather reveals a deep history of Spanish goats‎

Ancient DNA reveals that denizens of the Iberian Peninsula made leather from domestic goats as far back as 7,000 years ago, according to a study published Nov. 4, 2026, in the journal PLOS One by Jolijn A. M. Erven of University College Dublin, Ireland, and colleagues.

Trained dogs detected invasive plant species in Germany with 75% accuracy‎

Invasive alien species (IAS) are one of the main causes of biodiversity loss worldwide. A study published Nov. 4, 2026, in the journal PLOS One by Annegret Grimm-Seyfarth at Helmholtz-Centre for Environmental Research—UFZ, Germany, and colleagues found that with training, volunteer dog-handler teams could locate invasive species in the wild with 75% accuracy.

Scientists discover there are way more bugs in California than you thought‎

A new study published in the journal Ecography finds that there are more than 60,000 different species of insects in California—and scientists have only described about two-thirds of them.

Five things to know about guiding sound for better communication‎

Every time someone picks up a call, the phone does a quiet bit of translation. Incoming radio signals are converted into tiny sound waves that ripple across chips before being turned back into data.

Molecular imaging reveals how shape-shifting protein complex captures DNA and holds separate sections together‎

Researchers at Kanazawa University and the National Institute of Genetics in Japan have used high-speed atomic force microscopy to observe how a group of proteins known as Smc5/6 interacts with DNA. The images reveal how this structure opens and closes, captures DNA and brings separate sections together. The researchers also observed Smc5/6 holding twisted sections of DNA in place, producing more tightly packed arrangements. The findings, published in Nature Communications, provide new insights into the molecular processes that contribute to the maintenance and repair of genetic material.

How a cell surface protein slows down the Ebola virus‎

The Ebola virus can cause severe, often life-threatening disease in humans. To replicate, it must enter human cells and exploit their cellular processes. In doing so, it encounters natural defense mechanisms that can make infection more difficult.
