Some brain disorders exhibit similar circuit malfunctions

Many neurodevelopmental disorders share similar symptoms, such as learning disabilities or attention deficits. A new study from MIT has uncovered a common neural mechanism for a type of cognitive impairment seen in some people with autism and schizophrenia, even though the genetic variations that produce the impairments are different for […]

Unlocking the power of the microbiome

Not only animals and humans host a complex community of microorganisms – plants do this as well. Researchers at ETH Zurich have recently published two new studies that shed light on fundamental aspects of these close – and often overlooked – relationships. Hundreds of different bacterial species live in and […]

Long Lived Mammals Exhibit Lower Plasma Methionine Levels

Mechanisms to sense levels of the essential amino acid methionine are one of the more important triggers for the beneficial calorie restriction response in mammals. Since the body doesn't manufacture methionine, it must come from the diet. Either a low calorie diet or a low methionine diet produce broadly similar […]

Autoantibodies: a possible contributor to fibromyalgia

Researchers at Karolinska Institutet and their British colleagues have identified a possible contributory cause of fibromyalgia, a difficult to treat pain condition. In a study on mice and human tissue, the researchers found that fibromyalgia patients’ antibodies played a key part in symptom development. The results, which are published in […]

Osmium activation in cancer cells

Cancer is a complex disease, and as such, there is not just a single way to tackle it. While cancer treatments are evolving towards personalised procedures, in most cases standard chemotherapy treatments are still required. In chemotherapy, platinum drugs such as cisplatin (approved 42 years ago by FDA) are used, […]

Scientists discover a new class of neurons for remembering faces

Scientists have long searched in vain for a class of brain cells that could explain the visceral flash of recognition that we feel when we see a very familiar face, like that of our grandmothers. But the proposed “grandmother neuron”—a single cell at the crossroads of sensory perception and memory, […]

New approach can add diversity to crop species without breeding GMOs

Genetic technique edits every chloroplast in a plant, but does not change nuclear DNA of offspring. Breeding better crops through genetic engineering have been possible for decades, but the use of genetically modified plants has been limited by technical challenges and popular controversies. A new approach potentially solves both of […]

Spatially resolved cellular model built of developing mouse

A new technique called sci-Space, combined with data from other technologies could lead to four-dimensional atlases of gene expression across diverse cells during the embryonic development of mammals. Such atlases would map how the gene transcripts in individual cells reflect the passage of time, cell lineages, cell migration, and location […]

Acid Ceramidase as a Potential Target for Future Senolytics

The accumulation of senescent cells is an important contributing cause of degenerative aging. This is not a recent discovery, enough was known 20 years ago for the first SENS rejuvenation research proposals to prominently feature removal of senescent cells as an approach to treating aging as a medical condition, but […]

Cell-based immunotherapy shows promise against melanoma

Immunotherapy based on supercharging the immune system’s natural killer cells has been effective in treating patients with recurrent leukemia and other difficult to treat blood cancers. Now, researchers at Washington University School of Medicine in St. Louis have shown in preclinical studies conducted in mice and human cells that this […]

Study maps effect of dietary fiber

The effect and selectivity of dietary fibers on intestinal bacteria is now demonstrated. In a series of controlled trials, researchers from DTU and Washington University School of Medicine, St. Louis (USA), show that plant-based fibers affect the microbiome of mice that host a human microbiota and as well as that […]

Eating disorder behaviors alter reward response in the brain

Researchers have found that eating disorder behaviors, such as binge-eating, alter the brain’s reward response process and food intake control circuitry, which can reinforce these behaviors. Understanding how eating disorder behaviors and neurobiology interact can shed light on why these disorders often become chronic and could aid in the future […]

Vaping increases susceptibility to coronavirus in mice

A new study finds that exposure to e-cigarette vapor leads to higher levels of the coronavirus receptor ACE-2 in lungs of mice, with nicotine enhancing that increase in male mice. The use of e-cigarettes, or vaping, causes serious damage to the lungs. After the novel coronavirus responsible for the respiratory […]

The Role of Aging Macrophages in Skin Inflammation

The immune system is complex and ages in complex ways, pressed by the lifetime burden of infection and rising levels of molecular damage that trigger many of the same innate immune responses as are produced by invading pathogens. The common innate immune cells known as macrophages play many roles in […]

COVID-19 vaccines show safety, immunity in infant model

A group of scientists led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian reported that the Moderna mRNA vaccine and a protein-based vaccine candidate elicited durable neutralizing antibody responses to SARS-CoV-2 in preclinical research. There were no adverse effects. The research, published […]

Using light to treat drug-resistant tumors

A chemist at The University of Texas at Arlington is developing a cancer medication that uses light to target and destroy tumor cells in a process known as photodynamic therapy (PDT). Sherri McFarland, professor of chemistry, and her team of researchers have developed a chemical compound containing the transition metal […]

How do sugary beverages affect the liver?

When people overconsume sugar-sweetened beverages, or SSBs, like soda, certain fruit juices, and some coffee and tea drinks, it can lead to many different health conditions, including obesity, cardiovascular disease and diabetes. Nonalcoholic fatty liver disease, or NAFLD, is the leading cause of liver disease in the United States, and […]

COVID-19 vaccine generates immune structures critical for lasting immunity

The first two COVID-19 vaccines authorized for emergency use by the Food and Drug Administration (FDA) employed a technology that had never before been used in FDA-approved vaccines. Both vaccines performed well in clinical trials, and both have been widely credited with reducing disease, but concerns remain over how long […]

New TAU method delivers therapeutic RNAs exclusively to cancer cells

Researchers at Tel Aviv University have created a new method of transporting RNA-based drugs to a subpopulation of immune cells involved in the inflammation process, and target disease-inflamed cells without causing damage to healthy cells that surround them. The new technology may revolutionize the treatment of cancer and a wide range of […]

In a dish, a mouse, crafted from stem cells, begins to form

The tiny mouse embryo has a heart that beats. Its muscles, blood vessels, gut and nervous system are beginning to develop. But this embryo is unusual: It was made in a lab, out of mouse embryonic stem cells, and represents the most sophisticated in vitro (in a dish) model of […]

Researcher seeks molecular causes for deadly lung, heart diseases

Yassine Sassi decided as a boy growing up in Tunisia that he wanted to be a scientist. He isn’t sure why. There were no scientists among his family, no friends with the same ambition. But at 18 he left home for France to study biochemistry. Two decades later, he’s on […]

Studying how microbiome affects immunity could improve vaccine effectiveness

So many microbes live in and on your body that it might be helpful to think of them functioning collectively as separate organs. That’s because these tiny organisms that live primarily in our gut, collectively known as the microbiome, often perform helpful functions that keep the body running smoothly. Scientists […]
