Solar activity likely to peak next year

Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.

Minimalist or maximalist? The life of a microbe a mile underground

Researchers characterize nearly 600 microbial genomes collected from goldmine. The study illuminates 'microbial dark matter' residing below the surface. Microbes divide into two groups: minimalists that have one, specialized job or maximalists that are prepared to use any available resource. Study has implications for how underground activities, like mining and carbon storage, could affect or...

Repairing nerve cells after injury and in chronic disease

Researchers discovered a mechanism for repairing damaged nerves during peripheral neuropathy in mice, wherein the protein Mitf orchestrates nerve repair after both trauma-induced and chronic nerve damage conditions, like Charcot Marie Tooth disease. Their findings may inspire novel therapeutics that bolster repair function and heal peripheral neuropathy -- even in hereditary and developmental...

First multi-chamber heart organoids unravel human heart development and disease

Heart disease kills 18 million people each year, but the development of new therapies faces a bottleneck: no physiological model of the entire human heart exists -- so far. A new multi-chamber organoid that mirrors the heart's intricate structure enables scientists to advance screening platforms for drug development, toxicology studies, and understanding heart development.

New material reduces bacterial infection and speeds up bone healing

Researchers have developed a new surgical implant that has the potential to transform the treatment of complex bone infections. When implanted on an injured or infected bone, the material can not only speed up bone healing, it also reduces the risk of infections without the need for traditional antibiotics. 

Macaque trials offer hope in pneumonia vaccine development

A research team has successfully developed a novel pneumococcal vaccine by combining the team's proprietary mucosal vaccine technology with pneumococcal surface proteins that can cover a wide range of serotypes. Experiments were conducted using mice and macaques and it was confirmed that pneumonia caused by pneumococcal infection was clearly suppressed in the target groups of animals inoculated...

Unlocking the secrets of cells, with AI

Researchers have developed a new program that provides a more accurate understanding of the peptide sequences in cells. The researchers use machine learning to help analyze the makeup of unfamiliar cells, which could lead to more personalized medicine in the treatment of cancer and other serious diseases.  

Compact accelerator technology achieves major energy milestone

Researchers have demonstrated a compact particle accelerator less than 20 meters long that produces an electron beam with an energy of 10 billion electron volts (10 GeV). There are only two other accelerators currently operating in the U.S. that can reach such high electron energies, but both are approximately 3 kilometers long. This type of accelerator is called a wakefield laser accelerator.

Discrimination during pregnancy can affect infant's brain circuitry

Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study finds. These effects, the researchers say, are separate from those caused by general stress and depression. The study was published in the journal Neuropsychopharmacology.

New framework for using AI in health care considers medical knowledge, practices, procedures, values

  Health care organizations are looking to artificial intelligence (AI) tools to improve patient care, but their translation into clinical settings has been inconsistent, in part because evaluating AI in health care remains challenging. In a new article, researchers propose a framework for using AI that includes practical guidance for applying values and that incorporates not just the tool's...

Researchers find neurons work as a team to process social interactions

Researchers have discovered that a part of the brain associated with working memory and multisensory integration may also play an important role in how the brain processes social cues. Previous research has shown that neurons in the ventrolateral prefrontal cortex (VLPFC) integrate faces and voices -- but new research shows that neurons in the VLPFC play a role in processing both the identity of...
