As head of the educational outreach arm of the Florida State University-headquartered National High Magnetic Field Laboratory, Roxanne Hughes has overseen dozens of science camps over the years, including numerous sessions of the successful SciGirls Summer Camp she co-organizes with WFSU .

In a new paper published in the Journal of Research in Science Teaching, Hughes and her colleagues took a much closer look at one of those camps, a coding camp for middle school girls.

Throughout the late 19th century, rivers across the southwestern United States were parceled out, and flows were diverted through irrigation canals and trapped behind dams. Growing populations put new demands on groundwater sources. Coupled with changing climate conditions, water tables sank and perennial streams began to run dry.

The fate of the Santa Cruz River in southeastern Arizona was no different.

CORVALLIS, Ore. - Squeezed by changing ocean conditions that limit their food options and the long-term loss of old forest needed for nesting, marbled murrelets would benefit most from conservation efforts that take both ocean and forest into account, new research by Oregon State University shows.

Published in Conservation Letters, the findings are based on two decades of murrelet surveys at nearly 20,000 sites in the Oregon Coast Range and illustrate how the elusive seabird is at risk of its habitat gradually shrinking to the point of local extinctions or worse.

TORONTO, Sept. 22, 2020 - Although less than one per cent of all water in the world is freshwater, it is what we drink and use for agriculture. In other words, it's vital to human survival. York University researchers have just created a publicly available water quality database for close to 12,000 freshwater lakes globally - almost half of the world's freshwater supply - that will help scientists monitor and manage the health of these lakes.

Biologists have long considered the origins and continued coexistence of the immense diversity of species found in our environment. How can we explain the fact that no single species predominates? A generally accepted hypothesis is that there are trade-offs, which means that no organism can do best in all conditions. One trade-off that is commonly assumed is that between gleaner organisms --which are able to acquire and consume more food than other species when resources are scarce-- and exploiters, which rapidly consume large quantities of the same resources when they are in abundance.

Confuciusornis was a crow-like fossil bird that lived in the Cretaceous ~120 million years ago. It was one of the first birds to evolve a beak (Fig. 1). Early beak evolution remains understudied. Using an imaging technique called Laser-Stimulated Fluorescence, researchers at the University of Hong Kong (HKU) address this by revealing just how different the beak and jaw of Confuciusornis were compared to birds we see today.

Based on current data measured in the energy, industry, and mobility sectors, restrictions of social life during the corona pandemic can be predicted to lead to a reduction of worldwide carbon dioxide emissions by up to eight percent in 2020. According to the Intergovernmental Panel on Climate Change (IPCC), cumulative reductions of about this magnitude would be required every year to reach the goals of the Paris Agreement by 2030.

For the first time ever the majority of Germans are limiting their consumption of meat, and many are open to the concept of eating cultured meat, according to a new study.

Liquid metals (LMs) are promising for applications in flexible electronics and biomimetic functional composites. Nanometerization and surface modification of LMs are usually used to improve their substrate affinity and processing properties. In most cases, LM nanodroplets are encapsulated into ultrathin and fragile shells of oxides or amphiphile monolayers.

However, it may be hindered from being incorporated homogeneously into various composites through conventional processing methods. Therefore, producing stable and processable LM nanodroplets remains challenging.

Doctors like to remind patients not to monkey around with their health, suggesting that a good diet and regular exercise improve longevity.

A new study on health in chimpanzees, which are the closest species to humans genetically, showed the benefits in what they eat and how they can travel and climb.

When chimpanzees have a plant-based diet and substantial opportunities to exercise, they fall into "healthy" human ranges. Lab chimpanzees, whose diet and exercise were limited, showed conditions indicative of cardiovascular disease risk, more like sedentary people.

It could be worth up to 8% of GDP per capita, exacerbate the differences between north and south, between society's rich and poor, as well as affect a number of Italy's strategic sectors: climate change is a risk accelerator for many aspects of both the economy and society. The report, "Analisi del rischio. I cambiamenti climatici in Italia – Risk Analysis. Climate Change in Italy" has been published. Realized by the CMCC Foundation, Euro-Mediterranean Center on Climate Change, it is the first integrated analysis of climate risk in Italy.

A discovery of more than a thousand dinosaur teeth, by a team of researchers from the University of Portsmouth, proves beyond reasonable doubt that Spinosaurus, the giant predator made famous by the movie Jurassic Park III as well as the BBC documentary Planet Dinosaur was an enormous river-monster.

Research published today in the journal Cretaceous Research proves that Spinosaurus aegyptiacus, a 15 metre long, six-tonne beast was in fact the most commonly found creature in the Kem Kem river system, which flowed through the Sahara Desert 100 million years ago.

Former Subtropical Storm Alpha was a short-lived storm that formed and fizzled within 24 hours. NASA-NOAA's Suomi NPP satellite found the remnants of former Subtropical storm Alpha spreading over Portugal and northwestern Spain.

Alpha formed off the coast of Portugal by 12:30 p.m. EDT (1630 UTC) on Friday, Sept. 18. Alpha made landfall in Portugal later that day around 5 p.m. EDT (2100 UTC) about 120 miles (195 km) north-northeast of Lisbon, Portugal.

The traditional rice-based diet of some east-Asian population has brought to a number of genomic adaptations that may contribute to mitigating the spread of diabetes and obesity. An international study led by the University of Bologna and published in the journal Evolutionary Applications has recently suggested this interesting hypothesis. Researchers analysed and compared the genomes of more than 2,000 subjects from 124 south-east-Asian populations.

Former Tropical Storm Wilfred weakened in the Central Atlantic Ocean and NASA-NOAA's Suomi NPP satellite provided a visible image after the storm became a trough or elongated area of low pressure.
