3D-printed robotic rattlesnake triggers an avoidance response in zoo animals, especially species which share their distribution with rattlers in nature

Lipid nanoparticles, or LNPs, best known as the delivery vehicle for the COVID-19 mRNA vaccines received by billions of people, are now at the center of a much larger medical revolution. Researchers are racing to use them to ferry therapeutic mRNA into cells for cancer therapies and treatments for inflammatory diseases, as well as delivering CRISPR constructs that can correct disease-causing gene mutations. But a stubborn problem has slowed progress on all of these fronts. For LNPs to work therapeutically, they must transfer their cargo into cells by fusing with cell membranes, and they ...

**EMBARGOED UNTIL MARCH 11 AT 2 P.M. ET** Johns Hopkins Medicine scientists say they have developed a simplified version of biodegradable nanoparticles that can “educate” the immune system to find and destroy disease-causing cells throughout the body. The study, they say, advances the field of engineering immune cells within a patient’s own body to combat cancers and autoimmune diseases including lupus, among other conditions. Engineered immune cells have been successfully used to treat an array of blood cancers, using CAR-T cells, or chimeric antigen receptor T cells. The treatment ...

BIRMINGHAM, Ala. – Early pregnancy depends on a remarkable act of coordination. Before the placenta can nourish a growing fetus, the embryo must securely “land” and connect with the mother’s blood supply — a process guided by a specialized group of immune cells called uterine natural killer cells, or uNK cells. A new peer-reviewed study from the University of Alabama at Birmingham, supported by the National Institutes of Health and published today in Science Translational Medicine, has uncovered a critical role in successful pregnancies for an immune switch ...

Google Earth’ for human organs made available online An international team of scientists and clinicians has announced, in Science Advances, the launch of a new open-access 3D portal that allows users to explore intact human organs in unprecedented detail — from the whole organ down to individual cells locally. The Human Organ Atlas, created using a powerful synchrotron imaging method, brings together some of the most detailed 3D images of human organs ever produced. It enables scientists, doctors, educators, students and the wider public to interactively “fly through” organs ...

ITHACA, N.Y. – Artificial intelligence-powered writing tools such as autocomplete suggestions can definitely change the way people express themselves, but can they also change how they think? Cornell Tech researchers think so. In two large-scale experiments, participants were exposed to a biased AI writing assistant that provided autocomplete suggestions as they wrote about societal issues like whether the death penalty should be abolished or whether fracking should be allowed. Using pre- and post-experiment surveys, the researchers found that participants ...

CHAMPAIGN, Ill. — In April 2019, a marine heat wave struck a coral reef on the island of Moorea in French Polynesia, killing much of the coral and the beneficial algae that colonized it. This “bleaching” event reduced live coral populations on the reef from about 75% beforehand to less than 17% a year later and led to a series of unexpected changes that have thwarted the reef’s recovery. A long-term study of the area is challenging scientists’ understanding of the cycles of destruction and repair that can occur on a coral ...

EL PASO, Texas (March 11, 2026) – A team of researchers from The University of Texas at El Paso has uncovered new evidence explaining why the rattlesnake’s rattle – one of nature’s most iconic warning signals – has persisted and proven so effective across millions of years. The study, which was published in the journal PLOS One, shows that rattling serves as a potent deterrent for a wide range of animals and is especially effective among species that naturally coexist with rattlesnakes. Led by Océane Da Cunha, Ph.D., lecturer and graduate student coordinator in UTEP’s College of Science, the research team engineered ...

Chimpanzees have a reputation for being aggressive, while bonobos are often seen as their peaceful counterparts. This contrast has frequently been used to explain different sides of human nature. However, a new study by Utrecht University behavioural biologists Emile Bryon, Edwin van Leeuwen, Tom Roth and international colleagues shows that, in zoos, chimpanzees are not more aggressive than bonobos. The study was published today in the scientific journal Science Advances. The team of researchers compared the occurrence ...

An enigmatic type of circulating tumor cell called a dual-positive (DP) cell is associated with shorter survival time in patients with advanced breast cancer, according to a study led by investigators at Weill Cornell Medicine and NewYork-Presbyterian. The findings highlight the potential importance of these under-studied cells in breast cancer progression. Circulating tumors cells are breakaway tumor cells that can seed secondary tumors (metastases) and are commonly detected in the blood of patients with cancer. Dual-positive ...

New research could help engineer crops that recover after extreme weather events Plants pause their growth during stress, then press play when conditions improve, helping them recover and live on to produce food, according to a new study. Published today in New Phytologist UBC researchers have pinpointed the genes and pathways responsible for recovery from the environmental stress of cold snaps in winter or overloads of salt when coastal fields flood. “With a changing climate and extreme weather events becoming more frequent, the work could help create climate resilient crops, where genetically ...
