Every summer from 2012 to 2016, Bruce MacFadden and a team of scientists accompanied K-12 teachers on an expedition to collect fossils around the Panama Canal. During this professional development program, educators learned from paleontologists how to identify fossils and worked with scientists to develop lesson plans to bring back to their classrooms. These scientist-teacher partnerships continued long after the expedition ended, as scientists made visits to the teachers' classrooms.

Millennial age groups—born mid 1980s to early 2000s—now have more money at hand than they have ever controlled before. And they are spending it, says Olivia Johnson, assistant professor in the Department of Human Development and Consumer Sciences at the University of Houston College of Technology.

Every year, families who celebrate Christmas decorate their tree and hang stockings in anticipation of the arrival of Santa Claus. But what does this have to do with the religious holiday itself?

At present, microbial fuel cells are mainly used in research laboratories to generate electricity. In order for industrial applications to be considered in the future, the fuel cells must be further developed so that they can produce consistently higher amounts of electricity than is currently the case.

Frida Kahlo, Arnold Schwarzenegger and Hercules—they are all among the namesakes of the new pseudoscorpions recently described in the Arachnology Department at the Museum der Natur Hamburg. The prominent names suit the little animals because they are reflected in their physique: They have comparatively massive "arms," the so-called pedipalps, which visually set them apart from most of their relatives. The species named after the Mexican artist is characterized by a particularly dense "fur" over the eye area.

Why do Republicans have a problem with ESG?

Future wind satellites should increase vertical resolution to better resolve gravity waves in the tropics, writes a team of researchers from the Leibniz Institute for Tropospheric Research (TROPOS), the European Space Agency (ESA), the European Centre for Medium-Range Weather Forecasts (ECMWF), the University of Hamburg and the Google company Loon. Their study has been published in the Quarterly Journal of the Royal Meteorological Society.

Fundamental technological changes often also cause profound social shifts. This is not only evident in the current case of digitalization, but also in the case of industrialization in the 19th century or the introduction of bronze as a work material about 4,000 years ago. Understanding such transitional periods in the past can therefore also help to better classify current processes.

The Bui National Park is one of the few areas where the common hippopotamus resides in Ghana. The combined resources of the Black Volta River and the abundance of grasses make the area very suitable for hippopotamus. However, in an attempt to solve the electricity crisis the country faced in 2007, the government of Ghana constructed a hydroelectric dam in the heart of their home.

Recently, scientists from the universities of Greifswald and Vienna examined skull remains of Europasaurus with high-resolution computer tomography scans. The little giant has been the ideal candidate for the researchers to investigate, since there are hardly any other sauropods with so much skull material from different ontogenetic stages. The respective study was published in eLife and suggests, among other things, that the species was precocial.

Every year, about a third of all food produced in the world—about 1.3 billion tons—is wasted in consumers' homes and retail businesses, according to the United Nations (UN). The food sector also accounts for around 30% of the world's total energy consumption and 22% of greenhouse gas emissions.

Electrochemical devices such as fuel cells are becoming indispensable for new power generation technologies because they can efficiently produce renewable energy. Ceramic proton conductors can be used in many applications, including protonic ceramic fuel cells (PCFCs), hydrogen pumps, sensors, and separation membranes. In particular, PCFCs based on ceramic proton conductors are promising, because they can work at lower temperatures compared with conventional solid oxide fuel cells (SOFCs), thanks...

The learning of digital skills is a complex process that is affected by older people's personal needs and motives as well as by societal, institutional, and learning situation related factors, according to recent international studies exploring older adults' learning of digital skills in Finland, Germany, Austria, Italy and Japan.

Where should we be building now that we are looking climate change in the face? Should we be investing in energy-intensive industries in low-lying areas of the Netherlands? How can cities be climate-resilient as they grow?

Today the international LHCb collaboration at the Large Hadron Collider (LHC) presented new measurements of rare particle transformations, or decays, that provide one of the highest-precision tests yet of a key property of the Standard Model of particle physics, known as lepton flavor universality.

Reality TV star Stephen Bear has been found guilty of two counts of disclosing private sexual photographs and films with intent to cause distress, and one of voyeurism after profiting from intimate images of his former girlfriend without her consent. Bear's conviction is a landmark moment in a climate where non-consensual sexual image sharing often goes unpunished.

Honeybee venom has been used in traditional medicine for centuries as an anti-inflammatory. Only its main component, melittin, has been scientifically well researched. However, with its strong effect, the natural substance can also damage healthy cells when used. A team of researchers from Frankfurt am Main and Giessen has now discovered milder melittin variants in evolutionarily older wild bee species that seem to be more usable for pharmacology.

Cleaning up greenhouse gases after they have been emitted should be incentivized by subsidies. New evidence from an economic analysis considering international markets suggests an important reason why subsidies should be higher than the price put on carbon emissions to incentivize their reduction.

Details of a major, updated online resource to help biomedical researchers use the best small-molecule reagents for their experiments have been published.

Buy Now, Pay Later (BNPL) services have dramatically changed the landscape of personal lending, largely by being easy to access and not charging interest—thus avoiding national credit laws.

With winter comes cold and flu season, making coughs and sneezes rife. But it isn't just humans who get struck down by these seasonal illnesses—our pets can too.

We're often told to limit our "screen time," thanks in part to the harsh blue light that screens can emit. Plants can detect blue light too, but instead of causing sleepless nights for our green friends, it could help make their fruits taste better. Researchers now report in the Journal of Agricultural and Food Chemistry that mangoes can become redder, sweeter and more ripe when exposed to blue light over several days.

Recent observations of a black hole devouring a wandering star may help scientists understand more complex black hole feeding behaviors.

It could be the end of the red dusty line for NASA's InSight lander, which has fallen silent after four years on Mars.

Canadian researchers measured wildlife overpasses around the world and found 71% in North America are narrower than recommended.
