Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomic structure responsible for this activity, but it is difficult to controllably remove them. A team has now shown that single atoms can be kicked out using a scanning transmission electron microscope under ultra-high vacuum.

The first image of the structures that power human cilia -- the tiny, hairlike projections that line our airways -- has now been produced and it could lead to much-needed treatments for people with rare cilial diseases.

Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.

Scientists develop positive electrode material using an organic redox polymer based on phenothiazine. Aluminium-ion batteries containing this material stored an unprecedented 167 milliampere hours per gram, outperforming batteries using graphite as electrode material. Aluminium-ion batteries are considered a promising alternative to conventional batteries that use scarce raw materials such as lithium.

Keto diets shrink pancreatic and colorectal tumors by starving them of the glucose they need to survive. But they also speed up development of a lethal wasting disease called cachexia. In mice, researchers have found that pairing keto with a corticosteroid prevents cachexia and increases survival.

Researchers are describing the results of a recent clinical trial -- a breakthrough in glioblastoma treatment with the help of a modified cold virus injected directly into the tumor. When combined with an immunotherapy drug, the authors observed a subset of patients that appeared to be living longer as a result of this therapy.

A new study found that a new vaccine against the deadly chytrid fungus in frogs can shift the composition of the microbiome, making frogs more resilient to future exposure to the fungus.

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.
