New study offers insights into how populations conform or go against the crowd
2025-01-17
Cultural traits — the information, beliefs, behaviors, customs, and practices that shape the character of a population — are influenced by conformity, the tendency to align with others, or anti-conformity, the choice to deliberately diverge. A new way to model this dynamic interplay could ultimately help explain societal phenomena like political polarization, cultural trends, and the spread of misinformation.
A study published in the Proceedings of the National Academy of Sciences outlines this novel approach. Presenting a mathematical model, SFI Complexity Postdoctoral Fellow Kaleda Denton with colleagues ...

The complexity of the human brain – 86 billion neurons strong with more than 100 trillion connections – enables abstract thinking, language acquisition, advanced reasoning and problem-solving, and the capacity for creativity and social interaction. Understanding how differences in brain signaling and dynamics produce unique cognition and behavior in individuals has long been a goal of neuroscience research, yet many phenomena remain unexplained.
A study from neuroscientists and ...
Technology for oxidizing atmospheric methane won’t help the climate
2025-01-17
As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to “geoengineer” climate-saving solutions, that is, alter the atmosphere at a global scale to either reduce the concentrations of carbon or mute its warming effect.
One recent proposal seeks to infuse the atmosphere with hydrogen peroxide, insisting that it would both oxidize methane (CH4), an extremely potent greenhouse gas while improving air quality.
Too good to be true?
University of Utah atmospheric scientists Alfred Mayhew and Jessica Haskins were skeptical, so they set out to test the claims behind this proposal. Their results, published on ...

EAST LANSING, Mich. – Our sun is essentially a searing hot sphere of gas. Its mix of primarily hydrogen and helium can reach temperatures between 10,000 and 3.6 million degrees Fahrenheit on its surface and its atmosphere’s outermost layer. Because of that heat, the blazing orb constantly oozes a stream of plasma, made up of charged subatomic particles — mainly protons and electrons. The sun’s gravity can’t contain them because they hold so much energy as heat, so they drift away into space as solar wind. Understanding how charged particles ...

New data shows how ‘rage giving’ boosted immigrant-serving nonprofits during the first Trump Administration
2025-01-17
As Donald Trump prepares to take office for a second term as President, research led by the University of California, Santa Cruz is demonstrating the important role nonprofits played during Trump’s first term as a counterforce that channeled public resistance to anti-immigrant policies.
The new study, published in the journal International Migration Review, shows how nonprofits that provide legal services for immigrants ended up receiving increases in public contributions in the wake of Trump's attacks on immigrants.
Previously, there had been many reported examples of this backlash effect, sometimes called ...
Unique characteristics of a rare liver cancer identified as clinical trial of new treatment begins
2025-01-17
Like many rare diseases, fibrolamellar hepatocellular carcinoma (FLC) mounts a ferocious attack against an unlucky few—in this case, children, adolescents, and young adults. Because its symptoms can vary from person to person, it’s often missed or misdiagnosed until it has metastasized and becomes lethal. Moreover, drug therapies for common liver cancers are not just useless for FLC patients but actually harmful.
But new insights about the disease, coupled with a just-launched clinical trial of a promising drug treatment, could significantly improve health outcomes. Researchers in Rockefeller University’s Laboratory of Cellular Biophysics, headed by Sanford ...

Panorama of our nearest galactic neighbor unveils hundreds of millions of stars
2025-01-17
In the decades following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way — the Andromeda Galaxy. It can be seen with the naked eye on clear autumn nights as a faint oval object roughly the size of the moon.
A century ago, astronomer Edwin Hubble first established that this so-called "spiral nebula" was approximately 2.5 million light years away from our own Milky Way galaxy.
Now, the space telescope named ...
A chain reaction: HIV vaccines can lead to antibodies against antibodies
2025-01-17
LA JOLLA, CA—Many vaccines work by introducing a protein to the body that resembles part of a virus. Ideally, the immune system will produce long-lasting antibodies recognizing that specific virus, thereby providing protection.
But Scripps Research scientists have now discovered that for some HIV vaccines, something else happens: after a few immunizations the immune system begins to produce antibodies against immune complexes already bound to the viral protein alone. They don’t yet know whether this chain reaction, described in Science ...
Bacteria in polymers form cables that grow into living gels
2025-01-17
Scientists at Caltech and Princeton University have discovered that bacterial cells growing in a solution of polymers, such as mucus, form long cables that buckle and twist on each other, building a kind of "living Jell-O."
The finding could be particularly important to the study and treatment of diseases such as cystic fibrosis, in which the mucus that lines the lungs becomes more concentrated, often causing bacterial infections that take hold in that mucus to become life threatening. This discovery ...
Rotavirus protein NSP4 manipulates gastrointestinal disease severity
2025-01-17
Researchers at Baylor College of Medicine and collaborating institutions have improved our understanding of how rotavirus, the most common cause of acute gastroenteritis in children, makes people sick. The study published in Science Advances is among the first to show that the rotavirus protein NSP4 is both necessary and sufficient for multiple aspects of rotavirus infection by disrupting calcium signaling not only within infected cells but also in nearby uninfected cells. These disruptions in calcium signaling affect rotavirus disease severity, providing new insights into how ...
‘Ding-dong:’ A study finds specific neurons with an immune doorbell
2025-01-17
Interleukin-1 (IL-1) is a key molecule involved in inflammation and plays an important role in both healthy and diseased states. In disease, high levels of IL-1 in the brain are linked to neuroinflammation, which can disrupt the body’s stress response, cause sickness-like behaviors, worsen inflammation by activating brain immune cells, and allow immune cells from the body to enter the brain. It also can lead to brain damage by causing support cells to produce harmful molecules. Elevated IL-1 levels are associated with mood disorders, ...
A major advance in biology combines DNA and RNA and could revolutionize cancer treatments
2025-01-17
Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA epigenetics comes in: a series of mechanisms that act as "markers" on genes, to control their activity without modifying the DNA or RNA sequence itself.
Until now, DNA and RNA epigenetics were studied as independent systems. These two mechanisms seemed to function separately, each playing its own role in distinct stages of the gene regulation process.
Perhaps that was a mistake.
