Morphological study of open clusters can provide observational evidence for tracing the formation mechanism of star clusters and help to explore the evolution of star clusters.

The morphology of open clusters on the two-dimensional (2D) projection planes mostly conforms to the core-shell structure. However, whether this layered structure actually exists in three-dimensional (3D) space is not known.

Recently, researchers from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences proposed a rose diagram overlaying method based on Gaia data to study the 3D layered structure of open samples within 500 parsec (pc) near the sun.

University of Alberta researchers have developed a new catalyst that could revolutionize how we generate power and purify water. When placed in any type of water and provided with a small amount of power, the catalyst produces hydrogen that can be fed into a fuel cell to generate electricity along with distilled water that is safe to drink.

The catalyst was discovered almost entirely by chance when Robin Hamilton was creating an electrode for an undergraduate student working on a waste biomass upcycling project. He mixed up a combination of powders and allowed them to sit overnight in water, intending to finish the cell the following day. When he returned in the morning, the mixture was bubbling—a reaction that was extremely out of the ordinary.

“It ends up being that when you mix these two things together, they interact, they work together and hydrogen comes off. It floored us,” says Hamilton, a senior research associate in the Department of Chemistry.

Suvorexant (Belsomra), a dual orexin receptor antagonist approved for insomnia, reduced levels of tau phosphorylation and amyloid beta, a small clinical trialopens in a new tab or window showed.

The ratio of phosphorylated tau-threonine-181 (p-tau-181) to unphosphorylated tau-threonine-181 decreased 10% to 15% in cognitively normal adults treated with suvorexant 20 mg compared with placebo, reported Brendan Lucey, MD, MSCI, of Washington University School of Medicine in St. Louis, and co-authors.

Amyloid-beta levels fell 10% to 20% compared with placebo starting 5 hours after suvorexant administration, the researchers wrote in Annals of Neurologyopens in a new tab or window.

— Both amyloid and tau levels fell in early trial.

Researchers from the Keck School of Medicine of USC have discovered that being exposed to a mixture of synthetic chemicals commonly present in the environment affects multiple crucial biological processes in both children and young adults. These processes include the metabolism of fats and amino acids.

<div class=””> <div class=””><br />Amino acids are a set of organic compounds used to build proteins. There are about 500 naturally occurring known amino acids, though only 20 appear in the genetic code. Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active. The amino acid sequences of proteins are encoded in the genes. Nine proteinogenic amino acids are called “essential” for humans because they cannot be produced from other compounds by the human body and so must be taken in as food.<br /></div> </div>

Researchers at Baylor College of Medicine have unraveled the processes that give astrocytes, the most abundant glial cell in the brain, their special bushy shape, which is fundamental for brain function. They report in the journal Nature that neuronal activity is necessary and sufficient for astrocytes to develop their complex shape, and interrupting this developmental process results in disrupted brain function.

“Astrocytes play diverse roles that are vital for proper ,” said first author Yi-Ting Cheng, a graduate student in Dr. Benjamin Deneen’s lab at Baylor. “For instance, they support the activity of other essential brain cells, neurons; participate in the formation and function of synapses, or neuron-to-neuron connections; release neurotransmitters, chemicals that mediate neuronal communication; and make the .”

In the adult brain, the bushy shape of is fundamentally linked to effective brain function. The ends of the branched-out astrocyte structure interact with neurons and regulate synaptic activity.

Join top executives in San Francisco on July 11–12, to hear how leaders are integrating and optimizing AI investments for success. Learn More

Today in the Moscone Center, San Francisco, at RSA Conference 2023 (RSAC), Google Cloud announced Google Cloud Security AI Workbench, a security platform powered by Sec-PaLM, a large language model (LLM) designed specifically for cybersecurity use cases.

Sec-PaLM modifies the organization’s existing PaLM model and processes Google’s proprietary threat intelligence data alongside Mandiant’s frontline intelligence to help identify and contain malicious activity, and coordinate response actions.
