An artificial material that can sense, adapt to its environment

Researchers have developed an artificial material which can respond to its environment, independently make a decision, and perform an action not directed by a human being. For example, a drone making a delivery might evaluate its environment including wind direction, speed or wildlife, and automatically change course in order to complete the delivery safely. The material incorporates 3 main...

Unexpected antibody type found in people with malaria infections

Malaria, a pathogen transmitted into blood by mosquitoes in tropical climates, is typically thought of as a blood and liver infection. However researchers have detected antibodies primarily made in response to infections in the mucous membranes -- in such areas as the lungs, intestines, or vagina -- in study participants with malaria.

Pinniped craniofacial musculature provides insight on its role in aquatic feeding

Pinnipeds—a group including seals, sea lions and walruses—are relatively recently derived marine mammals that evolved from terrestrial carnivorans and reentered the marine environment. Their recent adaptations to an amphibious lifestyle make their evolutionary anatomy of particular interest to Baylor University researcher Sarah Kienle, Ph.D., assistant professor of biology.

Rocky exoplanets are even stranger than we thought

An astronomer from NSF's NOIRLab has teamed up with a geologist from California State University, Fresno, to make the first estimates of rock types that exist on planets orbiting nearby stars. After studying the chemical composition of "polluted" white dwarfs, they have concluded that most rocky planets orbiting nearby stars are more diverse and exotic than previously thought, with types of rocks...

Researchers quantify the role of the pandemic in the 2020 US elections

In the media, a prevalent narrative is that Donald Trump lost the 2020 elections because of the way he handled the COVID-19 pandemic. Several researchers determined that Trump would have won the electoral vote and lost the popular vote, as he did in 2016, if the pandemic had not occurred or if it had been mitigated.

What's Up - November 2021

Enjoy the Moon and planets after sunset all month, plus a lunar eclipse! A partial lunar eclipse will be visible to much of the world on Nov. 18 and 19. Also, the familiar stars of Northern Hemisphere winter (or Southern summer) are returning to late night skies. In particular, note that several destinations of NASA's Lucy mission are located near the Pleiades. Additional information about...

NASA’s new rovers will be a fleet of mobile robots that work together

NASA is exploring a concept for a new fleet of mini-rovers that can work together to solve problems and make decisions as a unit. If one fails or gets stuck somewhere, the others could carry on without it. As part of the Cooperative Autonomous Distributed Robotic Exploration (CADRE) project, NASA engineers are designing compact, mobile robots the size of a shoebox (for comparison, Perseverance...

Hybrid cloud adoption demands a holistic cybersecurity posture

This is the second article in a series of three. The first focused on the importance of making businesses more future-ready and how to work through common obstacles on the path to digitization. We also discussed how modernizing on-premises infrastructure as part of a hybrid cloud approach can best be managed via hyperconverged infrastructure (HCI), enabling modernization that blends the best of...

A sequence change in a single protein allowed a tomato virus to become a global crop pandemic

In the last years, a new viral tomato disease has emerged, threatening tomato production worldwide. This is caused by the Tomato brown rugose fruit virus (ToBRFV), a member of a devastating group of plant viruses called tobamoviruses. ToBRFV overcomes all known tobamovirus resistance in tomato, including the one conferred by Tm-22, a resistance gene responsible for the stable resistance to these...
