While small, the hypothalamus – a complex structure located deep in the brain – plays a gargantuan role in coordinating the wide array of neuronal signals that are responsible for keeping the body in a stable state. In a Special Issue of Science, authors across four Reviews unpack this key brain region’s impact on physiological and behavioral homeostasis. The hypothalamus consists of a complex collection of neural circuits. These circuits receive, process, and integrate sensory inputs to drive coordinated communication via a range of behavioral, ...

In a Perspective, Stephen Tang and Samuel Sternberg discuss retroelement-based gene editing as a safer alternative to CRISPR-Cas approaches. Precision genome editing technologies have transformed modern biology. Capabilities for programable DNA targeting have improved rapidly, largely due to the development of bacterial RNA-guided CRISPR-Cas systems, which allow precise cleavage of target DNA sequences. However, CRISPR-Cas9 systems generate a DNA double strand break (DSB), which activates cellular DNA repair pathways that can lead to unwanted and complex byproducts, ...

Key takeaways Female chimpanzees in Uganda’s Ngogo community experienced a menopausal transition similar to women. Fertility among chimpanzees studied declined after age 30, and no births were observed after age 50. The data can help researchers better understand why menopause and post-fertile survival occur in nature and how it evolved in the human species.  A team of researchers studying the Ngogo community of wild chimpanzees in western Uganda’s Kibale National Park for two decades has published a report in Science showing that females in this population can ...

The hardness of materials is determined by the strength of the chemical bonds that are formed between the electrons of the neighbouring atoms.  For example, the bonds in diamond are very strong, so it is one of the hardest materials known.  The bonding is rooted in the laws of quantum mechanics, and the complex compounds that are of most interest in forefront research today are known as ‘quantum materials.’  In many quantum materials, layers of strongly bonded atoms separate layers in ...

The basic idea is simple: unlike previous chips, where only calculations were carried out on transistors, they are now the location of data storage as well. That saves time and energy. “As a result, the performance of the chips is also boosted,” says Hussam Amrouch, a professor of AI processor design at the Technical University of Munich (TUM). The transistors on which he performs calculations and stores data measure just 28 nanometers, with millions of them placed on each of the new AI chips. The chips of the future will have to be faster and more efficient than earlier ones. Consequently, ...

DANVILLE, Pa. – Genomic screening to identify hemochromatosis—a disorder that causes iron levels in the body to rise to dangerous levels—encourages people with the condition to seek treatment and ongoing management, a Geisinger study found. Hereditary hemochromatosis type 1 (HH1), caused by a change in the HFE gene, is underdiagnosed, often resulting in missed opportunities for early and consistent treatment. Without treatment, hemochromatosis can cause iron overload, a buildup of iron that can damage many parts of the body. Treatment of hemochromatosis includes regular monitoring of iron levels and removing excess iron ...

WOODS HOLE, Mass.— At the surface, salt marshes and their windswept grasses can look deceptively simple. But those marshes are teeming with biodiversity, from the insects and migrating birds in the air all the way down to the microbes that live in the soil. Scientists from the Marine Biological Laboratory (MBL) have discovered that even among the sulfur-cycling microbes that are responsible for the “rotten egg gas” smell in salt marsh air, diversity extends all the way to genomes and even to individual nucleotides. To ...

Children who are too short for their age can suffer reduced cognitive ability arising from differences in brain function as early as six months of age, according to new research from the University of East Anglia. Researchers compared the ‘visual working memory’ – the memory capacity that holds visual cues for processing – in children who had stunted growth with those having typical growth. Published today in the journal Nature Human Behaviour, the study found that the visual ...

A team of scientists led by KOO Sagang from the Seoul National University and Center for Nanoparticle Research within the Institue for Basic Science Center (IBS), in collaboration with researchers from Korea Institute of Science and Technology (KIST) and the Seoul National University, developed a new solution for the treatment of rheumatoid arthritis (RA). RA is a chronic disease that, unfortunately, has no cure. The disease triggers a mix of troublesome symptoms like inflamed joints, harmful cytokines, and immune system imbalances, which work together to create a relentless cycle of worsening symptoms. While targeting ...

About The Study: The results of this study of 41 large U.S. children’s hospitals suggest that bronchiolitis hospitalizations decreased transiently and then increased markedly during the COVID-19 pandemic era. Patients admitted during the pandemic era were older and were more likely to be admitted to an intensive care unit. These findings suggest that bronchiolitis seasonality has not yet returned to pre-pandemic patterns, and hospitals should prepare for the possibility of atypical timing again in 2023.  Authors: Jonathan H. Pelletier, ...

About The Study: This survey study of attitudes of 1,005 parents of children and adolescents ages 9 to 15 revealed both perceived benefits (e.g., family connectedness) and concerns (e.g., cyberbullying, addiction) of internet use.

CAMBRIDGE, MA -- When babies first begin to talk, their vocabulary is very limited. Often one of the first sounds they generate is “da,” which may refer to dad, a dog, a dot, or nothing at all. How does an adult listener make sense of this limited verbal repertoire? A new study from MIT and Harvard University researchers has found that adults’ understanding of conversational context and knowledge of mispronunciations that children commonly make are critical to the ability to understand children’s early linguistic efforts.  Using ...
