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 ...

New spider species in the Amazon mimics parasitic fungus

An international research team, including the Leibniz Institute for the Analysis of Biodiversity Change (LIB), has described a new species of spider from the Ecuadorian Amazon: Taczanowskia waska. The species is characterized ...

Researchers clarify how cells remove damaged endoplasmic reticulum

The cell's endoplasmic reticulum (ER) plays a central role in protein synthesis, folding, and calcium (Ca²⁺) storage. When damaged, ER-phagy (self-eating) removes affected ER regions via double-membrane vesicles called autophagosomes. ...

Earth from space: Eyes on our moon

In an unusual perspective for an Earth-observing satellite, the Copernicus Sentinel-2 mission captured this image of the moon, Earth's only natural satellite. The Sentinel-2 mission acquired this lunar image by rolling one ...

Webb eyes a pair of planet-forming disks

This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with some potential planets thrown in as well. This visual highlights Webb's views of the protoplanetary ...

Map shows scale of ecosystem disturbance across Australia

University of Queensland researchers are urging governments to use newly created national data to protect the country's last remaining ecosystems free of human pressures. The two new datasets map the extent of ecosystem disturbance ...
