Solid-state batteries use solid electrodes and solid electrolytes, unlike the more commonly known lithium-ion batteries, which use liquid electrolytes. Solid-state batteries overcome various challenges associated with liquid-based batteries, such as flammability, limited voltage, unstable reactants, and poor long-term cyclability and strength. Making advances in this field, researchers recently demonstrated an all-solid-state rechargeable air battery composed of a redox-active organic negative electrode and a proton-conductive polymer electrolyte.

Giraffes in the East African savannahs are adapting surprisingly well to the rising temperatures caused by climate change. However, they are threatened by increasingly heavy rainfall, as researchers have shown.

The largest survey and data compilation of its kind --- from more than 21,000 dog owners --- has revealed the social determinants that may be tied to healthier aging for people's beloved canine companions. Among them, a measurement of the amount of a dog's social support network proved to have the greatest influence and association on better health outcomes -- 5 times the effect of financial factors, household stability or the age of the owner.

For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals from the central nervous system (CNS) to the semi-autonomous nervous system within the gastrointestinal (GI) tract, called the enteric nervous system (ENS). These psychological stress signals can cause inflammation and exacerbate symptoms of inflammatory bowel disease (IBD).

A study finds that deficiency of taurine, a molecule produced in our bodies, drives aging, and taurine supplements can improve health and increase lifespan in animals.

A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.

Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.

Nutrition is an important part of any top athlete's training program. And now, a new study proposes that supplementing the diet of athletes with colorful fruits and vegetables could improve their visual range. The paper examines how a group of plant compounds that build up in the retina, known as macular pigments, work to improve eye health and functional vision.

Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.

Octopuses don't thermoregulate, so their powerful brains are exposed to -- and potentially threatened by -- changes in temperature. Researchers report that two-spot octopuses adapt to seasonal temperature shifts by producing different neural proteins under warm versus cool conditions. The octopuses achieve this by editing their RNA, the messenger molecule between DNA and proteins. This rewiring likely protects their brains, and the researchers suspect that this unusual strategy is used widely amongst octopuses and squid.

A new paper argues that materials like wood, bacteria, and fungi belong to a newly identified class of matter, 'hydration solids.' The new findings emerged from ongoing research into the strange behavior of spores, dormant bacterial cells.

Newly discovered biomarker signatures point to a whole range of previously unknown organisms that dominated complex life on Earth about a billion years ago. They differed from complex eukaryotic life as we know it, such as animals, plants and algae in their cell structure and likely metabolism, which was adapted to a world that had far less oxygen in the atmosphere than today.

Social ants are masters of cooperative disease defense. They collectively take care of each other to prevent the spread of infections within a colony. But how does an individual ant know whom it should groom? A multidisciplinary team of researchers combined experimental and theoretical approaches to get a detailed look into ants' sanitary decision-making.
