Phys.org / Beyond the algorithm, online negativity takes on a life of its own as users try to stand out
It doesn't take a scientist to figure out that social media can trend toward the negative. But it might take one to figure out why. In a new paper in PNAS, professor of psychology Joshua Conrad Jackson and colleagues show ...
Phys.org / How to fine-tune molecular structures within vaccines to improve immune responses
A vaccine's molecular structure plays a key role in determining how the immune system responds and prepares to protect the body from future exposure to a specific pathogen. To develop a vaccine that offers long-term protection ...
Phys.org / Early hardship may shape how oxytocin influences altruism
While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances ...
Phys.org / India faces rising uncompensable heat stress, especially during monsoon season
Animals struggle to cool down in extreme heat and high humidity, and heat stress is rising in many regions around the world. This is especially true for people in tropical countries, including populous India. In a new paper ...
Phys.org / A new category of heat waves is melting western US snowpack faster
Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science ...
Phys.org / Active supermassive black holes may help form massive planets
A popular myth about black holes is that they act like giant cosmic vacuum cleaners, sucking in everything around them. But Wladimir Lyra's research found a new mechanism around supermassive black holes that is more like ...
Phys.org / Protein-like nanoparticles sort themselves inside growing crystals, enabling controlled release
The tiny bones in your fingers withstand countless taps and swipes thanks to a precise blend of materials. Flexible collagen fibers form the framework, reinforced by hard calcium phosphate hydroxyapatite crystals. This is ...
Phys.org / Complex suicidal somersault behavior in male redback spiders may be explained by surprisingly simple genetics
The Australian redback spider (Latrodectus hasselti), a cousin of the North American black widow spider, is known to practice sexual cannibalism, which is somewhat common among spider species. However, the male Australian ...
Phys.org / Paleontologists reconstruct forests of 56 million years ago with chilling parallels for our warming planet
If you want to know how rapidly pumping carbon dioxide into the atmosphere will affect future forest ecosystems, you have to look into the distant past. The researchers behind a new study published in Science have done just ...
Phys.org / CRISPR roadblocks: Scientists identify genes blocking gene therapy success
Like a delivery driver navigating crowded city streets, a gene-therapy-toting lipid nanoparticle faces a gauntlet of potential detours on its journey toward a cell's nucleus. First, there's entering the cell's plasma membrane; ...
Phys.org / Melting diamond could unlock triple fusion gain and the secrets of ice giant planets
Diamond is more than a dazzling gem—the extremely hard form of carbon makes up the pellet that encases fuel for inertial confinement fusion, and scientists believe it rains down deep inside ice giant planets like Neptune ...
Phys.org / Climate change decided who ruled as top predator 35 million years ago
An international team of researchers from Belgium, France, Switzerland, Spain and the U.S. has reconstructed the evolution of body mass in carnivorous mammals during the Paleogene—a crucial window in the diversification of ...
