No more giants, no more heavy handaxes: Why early humans downsized their stone tools

For more than 1 million years, early humans in the Levant region of the eastern Mediterranean used a range of heavy tools, such as massive handaxes and stone balls, for important tasks, including processing animal carcasses. ...

How surface chemistry impacts the performance of malaria nets

Insecticide-treated bed nets remain one of the most effective tools in malaria prevention, acting both as a physical barrier and as an insecticidal surface that kills or disables mosquitoes before they can transmit disease. ...

Rock bonding changes understanding of earthquake mechanics

When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is suddenly released—resulting in an earthquake. What exactly governs this behavior remains one of the ...

Fat-producing enzyme may amplify damage in Parkinson's disease

A fat-producing enzyme in brain cells may play a key role in driving damage in Parkinson's disease and could offer a new target for treatment, scientists at Nanyang Technological University, Singapore (NTU Singapore) have ...

What if dark matter came in two states?

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...

Skin can 'pre-learn': Priming cells for regeneration before injury

It is well known that students who prepare in advance perform better in exams. Now, it appears that the skin can do the same. Rather than scrambling to repair itself only after injury occurs, a Korean research team has demonstrated ...

Why treelines don't simply rise with the climate

A global study by the University of Basel, Switzerland, reveals a surprising picture: While 42% of treelines worldwide are shifting upslope, 25% are retreating. This seemingly contradictory trend involves more than just warming. ...

Twin NASA control rooms support Artemis safety, success

Twin control rooms at NASA's Marshall Space Flight Center in Huntsville, Alabama, are actively supporting real-time mission operations in lunar orbit as part of the agency's Artemis II mission, helping ensure astronaut safety ...

Emperor penguins listed as endangered species: IUCN

The emperor penguin has been declared an endangered species as climate change pushes the icon of Antarctica a step closer to extinction, the global authority on threatened wildlife announced on Thursday.

New study reveals the depth of children's nuclear anxiety

As geopolitical tensions rise globally, a new study published in Critical Studies on Security warns that the shadow of the "mushroom cloud" is weighing heavily on the next generation. The research paper, titled "Mushrooms, ...

New Hampshire ski industry concerned about climate change

New research out of the University of New Hampshire reveals that the majority of New Hampshire ski industry professionals are concerned about the effects of global warming on the ski industry, which generates close to $278.8 ...

Quantum computing without interruptions

Mid-circuit measurements are one of the biggest practical hurdles in quantum error correction on encoded qubits. Researchers in Innsbruck and Aachen have now proposed and experimentally demonstrated that a universal fault-tolerant ...

A layered approach sharpens brain signals in optical imaging

Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near-infrared light into ...

Oyster reefs stack up for shoreline protection

Oyster reef living shorelines have been found to provide a resilient and adaptive alternative to conventional hard coastal protection, reducing wave energy while supporting oyster colonization.

A color-changing phosphor can encode information

A new synthetic molecule switches between emitting green and blue light after application of a solvent or mild heat. The color-changing phosphor can be leveraged for a two-layered information encoding platform, according ...

What it takes to keep astronauts safe in deep space

The Artemis II mission launches this week as a first step toward returning to the moon and reaching Mars. Materials scientist Debbie Senesky explains the material tech that makes these missions possible.

5 reasons why the Artemis II mission is a big deal

The Artemis II mission, scheduled to launch on Wednesday, will send four astronauts on a 10-day journey from Earth around the moon—the first time humans will travel that far into space since 1972. While the crew will not ...

Could a solar storm derail the Artemis II mission?

Every mission to deep space is fraught with danger. A hardware failure during launch, an equipment malfunction far from Earth, or a small space rock hitting the vehicle are all scenarios astronauts will train for.

Is true empathy possible between humans and AI?

As artificial intelligence (AI) continues to influence all facets of our personal and professional lives, questions abound, like, "Can people have actual feelings for robots?" or "Can a chatbot comfort someone in distress?" ...
