Significance of astrocyte–neuron interactions in fine-tuning brain function

Humans learn to handle a variety of skilled movements throughout their lives, from driving a car to swinging a tennis racket. Neurons are not the only ones who implement this learning, but a new study from The Picower Institute for Learning and Memory at MIT shows that astrocytes play an important role as well.

Experts unravel a vast network that shows how cells adjust in real-time to withstand stresses

Every minute of every day, our body adapts to meet the needs of each moment. When we binge on carbs, exercise, or become sick, chemical reactions inside our cells switch on, slow down, or shift strategy so that we have the energy and strength we need.

Demonstrating the effects of wildflowers on the health and reproduction rate of bumblebees

University of Massachusetts Amherst biologist Lynn Adler has won the Mahoney Life Sciences Prize for her research demonstrating that different kinds of wildflowers can have markedly different effects on the health and reproduction rate of bumblebees.

Analyzing the antimicrobial resistance profile of the main agent of urinary tract infections

The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora. In most people, it contributes to wellness. A healthy gut indicates a stronger immune system, improved metabolism, and a healthy brain and heart, among other functions.

Developing new therapies that leverage the host immune system

Yersinia bacteria cause a variety of human and animal diseases, the most notorious being the plague, caused by Yersinia pestis. A relative, Yersinia pseudotuberculosis, causes gastrointestinal illness and is less deadly but naturally infects both mice and humans, making it a useful model for studying its interactions with the immune system.

Protecting normal cells from chemotherapy, while eliminating drug-resistant cancer cells

A new review paper was published in Oncotarget's Volume 14 on March 11, 2023, entitled, "Selective protection of normal cells from chemotherapy, while killing drug-resistant cancer cells."

Understanding the relationship between gut microbiome and CAR T-cell therapy response

Microorganisms live in or on almost every part of the human body and play an important role in the regulation of normal human processes. As a result, changes in the number or type of microorganisms, also known as the microbiome, can contribute to disease and altered responses to therapy, including cancer treatment.

Study investigates schizophrenia risk across African ancestry

Researchers have identified two previously unknown genes linked to schizophrenia and newly implicated a third gene as carrying risk for both schizophrenia and autism. Led by the Icahn School of Medicine at Mount Sinai, the multi-center study further demonstrated that the schizophrenia risk conferred by these rare damaging variants is conserved across ethnicities. The study may also point to new therapeutics.

Bacteriophages might hold the key to fighting antibiotic resistance

As conventional antibiotics continue to lose effectiveness against evolving pathogens, scientists are keen to employ the bacteria-killing techniques perfected by bacteriophages, the viruses that infect bacteria.

Neural-network-based image recognition models for examining SCC defects

Scientists from Tokyo Metropolitan University have used machine learning to automate the identification of defects in sister chromatid cohesion. They trained a convolutional neural network (CNN) with microscopy images of individual stained chromosomes, identified by researchers as having or not having cohesion defects. After training, it was able to successfully classify 73.1% of new images. Automation promises better statistics, and more insight into the wide range of disorders which cause cohesion defects.

New class of oral drugs inhibits a diverse range of SARS-CoV-2 strains

The constant evolution of new COVID-19 variants makes it critical for clinicians to have multiple therapies in their arsenal for treating drug-resistant infections. Researchers have now discovered that a new class of oral drugs that acts directly on human cells can inhibit a diverse range of pathogenic SARS-CoV-2 strains.

Study investigates the complex evolutionary history of jewel beetles' vision

Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. Possessing large, well-developed eyes, jewel beetles use vision and color for a range of different behaviors, including finding mates and host plants.

Rest boosts the immune system of migratory birds, study finds

Exercising too much and not getting enough rest is bad for your health. A new study from Lund University in Sweden shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system.

Novel platform identifies genes that control biologic processes

Inflammatory neurological diseases, such as multiple sclerosis (MS), can arise when cell-to-cell communication between cells in the central nervous system (CNS) goes awry. But exactly how this cellular crosstalk leads to the molecular changes that drive disease remain unknown.

A reliable way to downregulate gene translation in plants

By carefully constructing upstream open reading frames (uORFs), Caixia Gao’s team at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) has created a new technique for downregulating gene translation to a predictable and desirable level in plants.

Antibiotic usage in livestock leaves an impact on soil carbon and climate

Soils are dependable carbon sinks, which is critical for minimizing the consequences of climate change. Grazing by large mammals promotes soil carbon storage in grasslands, but livestock is progressively replacing wild herbivores across the world.
