This puzzle challenges readers to divide a T-shaped figure into three parts that can be rearranged into a square. The figure is made up of 25 small squares, with a target square size of 5x5. The solution requires cuts that don't follow the grid lines, using diagonal cuts with a length of 5 based on the Pythagorean theorem. The puzzle encourages creative thinking and spatial reasoning skills.
Robeauté, a French startup, secured $28 million to create a tiny, self-propelled microrobot for brain surgeries, aiming to assist in biopsies, drug delivery, and electrode implantation with minimal damage, with potential human...
The new hydrogen-based energy system for underwater robots extracts oxygen from seawater using membrane technology, providing a sustainable alternative to lithium batteries and enabling longer operating times for autonomous...
SpaceX's Starship rocket exploded mid-flight, leading to an FAA investigation, flight delays, and a requirement for SpaceX to identify the cause and implement corrective measures before future Starship missions can proceed.
Researchers have developed a new lithium-sulfur battery with significantly improved performance. The battery retains over 80% capacity after 25,000 charge/discharge cycles, far surpassing typical lithium-ion batteries, by using a...
SpaceX's seventh Starship test flight ended with a successful landing of the first stage but an explosion of the upper stage over the Atlantic Ocean. Elon Musk suggested the likely cause was an oxygen/fuel leak that created...

Researchers at UC San Diego are developing robots for construction tasks, aiming to enhance safety and efficiency through 3D mapping and reconstruction. The $786,500 project, set to conclude in 2027, focuses on enabling a single...
Earth tides strongly influence electrical signals in trees, with five major tides explaining most data variability across species, suggesting an electrokinetic mechanism may drive sap flow in trees.
A groundbreaking renewable energy project in Abu Dhabi combines solar generation and energy storage on an unprecedented scale. The facility will provide 1GW of continuous power using a 5.2GW solar plant and a 19GWh battery...
The US Defense Health Agency has contracted Aptima Inc. to develop fORE, a wearable neuro-cognitive monitoring system for military pilots using fNIRS technology. This compact device provides real-time assessment of aviators'...
DeepSee, a new interactive data visualization tool, helps scientists study deep ocean ecosystems more effectively using limited sediment samples. The system integrates 2D and 3D visualizations of biogeochemical data with seafloor...
China is developing a 1-kilometer-wide space-based solar power station to collect and convert solar energy in orbit. The station would beam energy back to Earth as microwaves, potentially generating more power annually than all...
Scientists observed unexpected rapid changes in a distant galaxy's black hole. The black hole, previously slow-growing, suddenly increased activity 100-fold in 2018 and again in 2023, emitting powerful radio waves and forming...
New measurements suggest the Moon formed primarily from Earth's mantle material, with minimal contribution from the protoplanet Theia. The findings also support the idea that Earth's water arrived early in its development,...
Northwestern University researchers have developed the first 2D mechanically interlocked polymer with high flexibility and strength. The material consists of 100 trillion mechanical bonds per square centimeter and could be used...
NASA's Pandora spacecraft bus is complete, keeping the exoplanet mission on track for a fall launch. The small satellite will study at least 20 known exoplanets, focusing on their atmospheres and overcoming challenges in...
NASA is revising plans to return rock samples collected by the Perseverance rover on Mars, aiming to cut costs and accelerate the timeline to the late 2030s. New strategies include using a "sky crane" landing system or large...
Recent breakthroughs in brain-computer interfaces are bringing us closer to prosthetic limbs with a sense of touch. Scientists have developed a method to stimulate the brain's touch centers, creating more stable and localized...
Leo P, a distant dwarf galaxy, has reignited star formation after a long pause, providing insights into galaxy evolution. NASA's James Webb Space Telescope observations reveal the galaxy formed stars early, stopped during the...
A new bioprocess converts CO2 and electricity into high-quality single-cell protein using a dual-reactor system. The protein has a 74% concentration, surpassing traditional sources like fish meal. This method reduces...
Astronomers have discovered a neutron star, ASKAP J1839-075, spinning extremely slowly at one rotation every 6.45 hours, challenging previous theories about these collapsed stars. This "pulsar" emits radio waves despite its slow...
Two private lunar landers, Firefly's Blue Ghost and ispace's Resilience, are en route to the Moon on a single SpaceX Falcon 9 rocket. Blue Ghost plans to land in Mare Crisium on March 2, carrying various instruments. Resilience...
A theoretical substance resembling two intermingled magnets can maintain an orderly pattern regardless of temperature, defying conventional physics wisdom. This discovery, made by researchers over the past few years, could impact...
Astronomers used the James Webb Space Telescope to analyze the composition of exoplanet K2 22b's interior by studying dust it emits. Surprisingly, the planet's dust contains unexpected materials like nitric oxide and carbon...
