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
- ScienceDaily
- 23/11/28 19:23
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.

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.
A new way to see the activity inside a living cell
- ScienceDaily
- 23/11/28 19:23
A new method allows scientists to label and image many different molecules at once within a living cell. The technique relies on 'switchable fluorophores' -- fluorescent proteins that turn on and off at a specific rate.

Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment.
Fish ecologist's research indicates need to conserve iconic migratory snook in Mexico
- ScienceDaily
- 23/11/28 19:23
Biologists investigated the snook’s almost 400-mile migration up into the rainforest habitat of the Usumacinta River. They have found that the snook, which connect aquatic food webs and support fisheries, spawn and start their lives in coastal nursery habitats before moving into river habitats that offer an array of food resources.
Study reveals hidden immune defense against cancer
- ScienceDaily
- 23/11/28 19:23
Researchers have found certain immune cells can still fight cancer even when the cancer cells lack an important protein that the immune system relies on to help track down cancer cells.
New material reduces bacterial infection and speeds up bone healing
- ScienceDaily
- 23/11/28 19:22
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
- ScienceDaily
- 23/11/28 06:14
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...
Nextgen computing: Hard-to-move quasiparticles glide up pyramid edges
- ScienceDaily
- 23/11/28 06:14
A new kind of 'wire' for moving excitons could help enable a new class of devices, perhaps including room temperature quantum computers.
Unlocking the secrets of cells, with AI
- ScienceDaily
- 23/11/28 06:14
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
- ScienceDaily
- 23/11/28 02:03
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.
Kids who feel their parents are less reliable take fewer risks vital to learning and growth
- ScienceDaily
- 23/11/28 00:07
The researchers studied decisions that more than 150 children ages 10 to 13 made while playing games that offered opportunities to risk a little and explore for potential gains.
Discrimination during pregnancy can affect infant's brain circuitry
- ScienceDaily
- 23/11/28 00:07
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.
