Ongoing climate change driven by greenhouse gas emissions is often discussed in terms of global average warming. For example, the landmark Paris Agreement seeks to limit global warming to 1.5 degrees C, relative to pre-industrial levels. However, the extent of future warming will not be the same throughout the planet. One of the clearest regional differences in climate change is the faster warming over land than sea. This 'terrestrial amplification' of future warming has real-world implications for understanding and dealing with climate change.

Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact -- mainly fishing --, but, are they enough to recover the functioning of these systems? A study now highlights the limitations of marine reserves in restoring food webs to their pristine state prior to the impact of intensive fishing.

Despite old fears that bad effects follow excessive video game playing or questionable game choices, researchers found those factors mattered little, if any, in children's brain health. The bad news? Video games assumed to be effective learning tools showed no meaningful effects, either.

New global modelling predicts the devastating socioeconomic impacts of future extreme coastal flooding for developing nations caused by climate change, with Asia, West Africa and Egypt facing severe costs in the coming decades.

In the course of five years, citizens who went on sailing cruises to the Arctic surveyed and collected plastic debris that had washed up on the shores of Svalbard. This has now been analyzed. According to the findings, one third of the plastic debris which still bore imprints or labels allowing an analysis of their origin came from Europe, and much of that number from Germany.

Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper shows.

The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.

With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.

A new study by mathematicians shows that math borrowed from neuroscience can describe how swarms of these unique insects coordinate their light show, capturing key details about how they behave in the wild.

Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.

Electronic gaming can precipitate life-threatening cardiac arrhythmias in susceptible children whose predisposition may have been previously unrecognized, according to a new report. The investigators documented an uncommon, but distinct pattern among children who lose consciousness while playing electronic (video) games.

Mathematical models indicate that as few as one in five cases of COVID-19 which occurred during the first 29 months of the pandemic are accounted for in the half billion cases officially reported.

'You're so smart!' -- This encouraging response may actually do more harm than good to children's math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities may dampen their math motivation and achievement over time.

Children's outbursts of rage while playing digital games are causing both concern and public debate around the topic. Taking a novel approach to gamer rage, a new study examines the topic from a child's perspective, finding complex reasons for gamer rage in children.

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.

Many people and companies worry about sensitive data getting hacked, so encrypting files with digital keys has become more commonplace. Now, researchers have developed a durable molecular encryption key from sequence-defined polymers that are built and deconstructed in a sequential way. They hid their molecular key in the ink of a letter, which was mailed and then used to decrypt a file with text from a classic story.

Australia has suffered a significant drop in teenage maths proficiency in the past 20 years -- sliding from 11th in the OECD rankings to 29th place out of 38 countries, prompting widespread debate over potential curriculum changes. One researcher says hand gestures could stop the slide.
