14-year-old Indian American girl builds system to predict driver fatigue, eyes $25,000 prize

31/07/2026
Fourteen-year-old Indian-American student Sharvi Mahajan has developed NeuroDrive Alert, an EEG-based machine learning system that tracks brain activity to predict driver fatigue before microsleep occurs. Her innovation has earned her a place among the 10 finalists of the 2026 3M Young Scientist Challenge, where she will compete for a $25,000 prize.

Texas engineers are building fish-like nano-robots that could harvest lithium from seawater and transform the future of clean energy

31/07/2026
Texas A&M engineers are developing fish-like nano-robots to harvest lithium from seawater. These autonomous microscopic robots use specialised particles activated by light for movement. This innovative approach offers a sustainable alternative to traditional land-based mining methods.

Tiny reef fish thrived near seabird islands; where rats wiped birds out, marine food chains changed

31/07/2026
Tropical islands are facing a surprising ecological shift as invasive rats disrupt the balance of coral reef ecosystems. By decimating seabird numbers, these rats cut down on essential nutrient contributions to the reefs. As a result, tiny cryptobenthic fish flourish in nutrient-rich spots, while invertebrates find success in less fertile regions, reshaping the food web and highlighting the vulnerable nature of these priceless underwater habitats.

Scientists transplanted 42 sea sponges into a polluted Spanish marina; 91.7% of one species survived

30/07/2026
In a remarkable experiment, scientists have introduced sea sponges into a polluted marina in Spain to investigate their resilience. The chicken kidney sponge, a particularly robust species, not only survived for an impressive 455 days but also showcased its remarkable ability to reproduce mobile clones. These developments indicate that sponges may play a critical role in ecological restoration, potentially aiding in the detoxification of contaminated coastal areas.

Meet Hikaru Kuribayashi: The 18-year-old teen who started with paper folds and ended with a $100,000 global science win

30/07/2026
A Japanese student explored origami to understand structural movement. His research focused on ladybug wings and their complex folding patterns. He developed a new model to represent multiple possible motions simultaneously. This innovative approach earned him international recognition and significant awards. His work connects traditional paper folding with modern physics and engineering.

Boreal forests shade permafrost so effectively that summer thaw stays about one metre shallower

30/07/2026
Thick forest canopies keep northern permafrost cool, safeguarding vast carbon stores. This natural shade prevents soil thawing and the release of greenhouse gases. Researchers discovered this vital cooling service has been largely overlooked in climate models. Losing these forests means losing this crucial protection for underground carbon. Protecting these boreal forests is therefore extremely important for global climate stability.

Scientists drilled 1,640 feet beneath Michigan and found 689 kinds of fungi living in water

30/07/2026
A fascinating discovery in Michigan reveals 689 fungal species living in ancient groundwater that hasn't touched the surface since the last Ice Age 11,000 years ago. This unique ecosystem, concealed within deep rocks and water, also harbors tiny organisms like worms and tardigrades. Such findings could revolutionize our understanding of subsurface life and fundamentally alter how scientists track the movement of underground carbon.

The 16,000-year-old Pando appears to be a forest, but scientists say all 47,000 trees belong to a single living organism

30/07/2026
Pando, a Utah aspen colony, is a single ancient organism. This massive organism spans 106 acres and weighs approximately 6,000 tonnes. Scientists estimate its root system is at least 16,000 years old. Grazing animals and altered natural patterns threaten new tree growth. Conservation efforts now focus on protecting young shoots for its survival.

New study suggests many dinosaurs may have died within hours, not months, after the asteroid struck Earth

30/07/2026
New research suggests asteroid impact caused immediate, intense heat pulses. Fine dust trapped thermal radiation, increasing surface temperatures significantly. This rapid heating killed many animals within hours of the impact. Burrowing creatures survived, while exposed animals faced lethal conditions. Heat and fire likely triggered the extinction before climate change effects.

Saturn’s largest moon Titan experiences clouds, rain, rivers and changing seasons like Earth

30/07/2026
Titan showcases an intriguing, elongated seasonal pattern due to Saturn's leisurely orbit. This fascinating moon is shrouded in a dense atmosphere with liquid methane rapidly flowing on its surface. Insights gathered from the Cassini spacecraft highlight not only the dynamic weather changes but also the enigmatic disappearance of lakes on Titan. Observations of varied wind directions and shifting sand dunes unveil the moon's remarkable seasonal climate transformations.

Scientists warn that more than 1.7 million planned satellites could create a new form of space pollution and permanently change the night sky

30/07/2026
Massive satellite constellations are changing the night sky's appearance and accessibility. New studies reveal over 1.7 million planned objects could compromise scientific observations. These satellites pose a significant threat to professional telescopes and data collection. Urgent international regulations are needed to protect the future of astronomical observation.

Why flamingos aren't born pink: The 1960s breakthrough that solved the mystery

30/07/2026
Flamingos obtain their striking pink color from dietary carotenoids found in algae and brine shrimp. These pigments are converted by the birds into compounds that accumulate in their feathers. Young flamingos hatch with muted colors and gradually develop pink as they mature. Different species exhibit varying shades of pink based on their specific food sources. This coloration plays a vital role in their survival and reproductive success.

New Zealand is investing $202 million in a mega-operation aimed at restoring three islands destroyed by invasive species

30/07/2026
In an inspiring ecological restoration project, New Zealand is teaming up with Māori natives to tackle invasive mammal populations on three major islands, including Maukahuka, Rakiura, and the Chatham archipelago. This extensive collaboration among governmental bodies, local communities, and Indigenous organizations aims to breathe new life into native wildlife. The success of this project could highlight New Zealand's pioneering methods in environmental restoration on the world stage.

Arika Kundu, 13, turns peanut shell waste into pesticide remover, competes for $25,000 prize

30/07/2026
Thirteen-year-old Minnesota student Arika Kundu has designed a method that uses discarded peanut shells to help remove pesticide residues from fresh fruits and vegetables. Her project, called LIGNEX, has made her one of 10 finalists in the 2026 3M Young Scientist Challenge. She will now compete for the $25,000 grand prize with guidance from a 3M scientist.
