UNIVERSITY PARK, Pa. — As the frequency and intensity of heatwaves increase across the U.S., a similar but more striking phenomenon is occurring in American rivers. Analysis of data from nearly 1,500 sites in the contiguous United States between 1980 and 2022 revealed that heatwaves in rivers are accelerating faster than and lasting nearly twice as long air heatwaves, according to a new study by researchers at Penn State.   “Rivers are often thought of as safe and cool havens protected from extreme temperatures,” said Li ...

STRICTLY EMBARGOED UNTIL 8PM UK TIME (3PM EASTERN TIME) ON MONDAY, SEPTEMBER 22   Hidden in plain sight, dried fish are an overlooked yet vital nutrient-packed superfood helping to feed millions of people across Africa, a new study reveals. And new evidence quantifies for the first time the essential nutrients in sun-dried and smoked fish in Africa, suggesting they could play an important role in tackling malnutrition across the tropics – provided the right policies are in place, researchers argue. Dried fish are an affordable and readily available food across the tropics. Yet despite this prevalence, because they are often ...

Tune into American politics today, and you'll hear something far more sinister than simple disagreement. The language has escalated: political parties trash talk each other—blaming rival parties for policy failures or even for causing incidents with national implications. And reducing polarization and "partisan animosity"—the distrust and hatred of the other party—is remarkably difficult, according to a new study published in the Proceedings of the National Academy of Sciences evaluating past attempts. The research was led by the Polarization ...

To the point: Conifers use resin to protect themselves against pests. This resin contains diterpenes, which are defensive substances.  Some of these diterpenes originated over 300 million years ago, before conifers evolved. Other diterpenes developed independently in different conifer species much later, presumably to protect against bark beetles. This repeated evolution was only possible because enzymes that produce diterpenes had previously undergone changes that unlocked evolutionary pathways towards certain substances. This is based on a mechanism called “epistasis”, which allows new traits to evolve once preparatory ...

Endocannabinoids are similar to the cannabinoids present in cannabis, but they are found naturally in the body. Endocannabinoids—and cannabinoids—work through a signaling system that supports neurodevelopment, but whether manipulating this system prenatally has long-lasting effects remains unclear. In a new JNeurosci paper, researchers led by Ismael Galve-Roperh, from the Complutense University of Madrid, used mice to explore this unknown.  The researchers decreased expression of an endocannabinoid receptor in the prefrontal cortex of prenatal mice and assessed the impact of this manipulation on gene expression, ...

In a collaboration between Turun yliopisto and the University of Turku, researchers led by Birgitta Paranko and Lauri Nummenmaa explored the immediate effects of bullying on the brain.  As reported in their JNeurosci paper, the researchers measured neural and attentional responses while tweens (aged 11 to 14) and adults watched first-person videos of either people being bullied or more positive social interactions. For participants of all ages, bullying triggered distressful alarm states, activating social and emotional brain networks as well as autonomic threat response systems. Measuring eye-tracking responses and pupil sizes in a separate group of adults during video viewing supported ...

Australian researchers have revealed a clear relationship between stress and increased disease risk in koalas in South East Queensland and on the New South Wales North Coast. A study led by Dr Michaela Blyton at The University of Queensland measured and tracked the level of koala retrovirus (KoRV) in groups of captive and wild koalas. “We wanted to see what happened to their KoRV loads over time and how it related to chlamydial infection and levels of the stress hormones cortisol and corticosterone in their faeces,” Dr Blyton said. “Virus load likely weakens the immune system, so those ...
