Researchers found a correlation between words used in media coverage related to weather or air quality, and transit ridership. It's not enough yet to say that media coverage causes changes in ridership. But it's enough to explore what factors in to a person's decision to ride transit and whether that decision can be nudged.

People who did not have a large heart rate response to a stress task surprised researchers later -- after the onset of the COVID-19 pandemic -- when they showed more symptoms of post-traumatic stress disorder related to the crisis than others who also did the stress task and COVID-19 stress ratings.
Cognitive flexibility, which refers to the brain's ability to switch between mental processes in response to external stimuli and different task demands, seems to begin developing during the first two years of life, which is much earlier than previously thought. Researchers used magnetic resonance imaging techniques to show the emergence of a functional flexible brain during early infancy.
In a new article, researchers propose reforms that the U.S. Food and Drug Administration (FDA) could implement to improve the emergency use authorization process and drug approvals during public health crises, which could increase the FDA's credibility and the public's trust in it.
Surveys and network analyses of 192 STEM faculty at three universities revealed that frequent users of evidence-based instructional practices are far more likely to engage one another than colleagues less familiar with the practices. The finding suggests that faculty networks alone are not enough to disseminate and drive the adoption of evidence-based practices that could improve undergraduate...
Researchers have investigated how the parasitic dodder Cuscuta australis controls flower formation. They showed that the parasite eavesdrops on the flowering signals of its host plants in order to activate its own flowering machinery. By synchronizing flowering with its host plant, the parasite makes sure that it can grow on its host long enough to produce the optimal amount of seeds.
Two studies provide empirical evidence to settle the question of whether being aggressively Machiavellian helps people get ahead. The studies concluded that being a jerk provides no advantage in career advancement. Any power boost disagreeable people get from being intimidating is offset by their poor interpersonal relationships, the studies concluded.
Researchers found that satellite imagery can identify non-native and invasive Amur honeysuckle, an ornamental shrub introduced from Asia that has spread in forests across much of the United States.
Structural biology techniques helped researchers target the nuclear receptor-binding SET domain family for the first time; its malfunction is associated with several types of cancer.
A new study identifies a specific gene's previously unknown role in fertility. When the gene is missing in fruit flies, roundworms, zebrafish and mice, the animals are infertile or lose their fertility unusually early but appear otherwise healthy. Analyzing genetic data in people, the researchers found an association between mutations in this gene and early menopause.
Researchers have developed a new material that could be used to make flexible X-ray detectors that are less harmful to the environment and cost less than existing technologies.

Exercise fights off stress by increasing levels of the brain protein galanin.
A study has found evidence for quantum fluctuations near a quantum critical point in a superconductor. Theory suggests that these quantum critical points may be analogous to black holes as places where all sorts of strange phenomena can exist in a quantum material.
Specific fungi in the gut associated with a higher risk of Alzheimer's disease and found in people with mild cognitive impairment (MCI) can be altered in a beneficial manner by eating a modified Mediterranean diet, researchers have found.
A team has discovered a missing link in the evolution of photosynthesis and carbon fixation. Dating back more than 2.4 billion years, a newly discovered form of the plant enzyme rubisco could give new insight into plant evolution and breeding.
Quantum-physical fundamentals can be studied particularly well by the interactions between electrons and photons. Excited with laser light, for example, the energy, mass or velocity of the electrons changes. A professor has invented a new toolbox to extend the theoretical description of electron-light interactions to the highest accurate level possible.
Researchers have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption.
A new solution to the problem of spring cleaning on the moon: Why not zap away the grime using a beam of electrons?
Elephant trails may lead the way to better conservation approaches. 'Think of elephants as engineers of the forests. Elephants shape the landscape in many ways that benefit humans. We're talking thousands of miles of trails. If we think about the loss of elephants over time, then we will see the forest structure change and human activities also would shift.'
A new study finds that reef-building corals emerged only when ocean conditions supported the construction of these creatures' stony skeletons, whereas diverse softer corals and sea anemones flourished at other times. Without a significant change to anthropogenic carbon emissions, the new findings present stark implications for the present and future of hard-bodied corals while suggesting a silver...
Cell phone location data shows that in counties where activity declined at workplaces and increased at home, coronavirus infection rates were lower.
A key to surviving in the wild is fighting off infection -- and not just once. For plants, as with humans, one infection may or may not leave a plant with lasting immunity. Biologists conducted a series of elegant experiments that capture how pathogen strains naturally accumulate on plants over a growing season. Their findings reveal the importance of understanding interactions among pathogens...
Repeated exposure to influenza viruses may undermine the effectiveness of the annual flu vaccine. A team of researchers has developed an approach to assess whether a vaccine activates the kind of immune cells needed for long-lasting immunity against new influenza strains. The findings could aid efforts to design an improved flu vaccine.
Researchers have identified specific sub-populations of brain cells in the prefrontal cortex, a key part of the brain that regulates social behavior, that are required for normal sociability in adulthood and are profoundly vulnerable to juvenile social isolation in mice.
Patients with newly diagnosed atrial fibrillation benefit from early rhythm control therapy, according to new results.
Researchers have developed a new microgel drug delivery method that could extend the effectiveness of pancreatic islet transplantations -- from several years to possibly the entire lifespan of a recipient.
