A Robot Designed to Enhance Structural Strength Leaves its Imprint in Wet Concrete

When we imagine freshly poured concrete, we usually think of leaving it to dry smoothly. However, a new robot, the Conit Runner, rolls over wet concrete, carving grooves to strengthen structures while reducing costs. Deep layers of wet concrete can crack as they dry, so concrete is typically poured in thin layers. To improve shear […]

This Meteorite Has Uncovered an Ancient Traces of Water on Mars

There is increasing evidence that Mars was once a wet and watery world, with lakes and oceans shaping its surface, leaving behind sediments that are now being carefully analyzed by rovers exploring the planet’s dry, dusty landscape. We know water existed on Mars, but determining exactly when, how, and where it went is more complex.

A Robotic Model Equipped with Real Pigeon Feathers Mimics Bird Flight

Robotics, Science / Valeriano Ndeyi

Ever wondered why airplanes have a vertical tailfin? It stabilizes their flight. While flying without one would be more energy-efficient, efforts to achieve this in aviation have yet to succeed. Interestingly, birds manage just fine without a vertical fin—so how do they achieve stability? Pigeon-Inspired Robotics David Lentink, a Professor of Biomimetics at the University

Spinal Cord Stimulation May Help Treat Chronic Pain

Healthcare, Medicine / Evelina Jeremias

A review published on Nov. 14 in JAMA Network Open suggests that spinal cord stimulation (SCS) for treating chronic back and/or lower extremity pain leads to greater pain relief compared to conventional medical management (CMM). Frank J. P. M. Huygen, Ph.D., M.D., from Erasmus Medical Center in Rotterdam, Netherlands, and his team conducted a systematic

SpaceX Starship Flight 6: No catch, But a Banana was Involved

Astronomy, Planetary Science / Marcílio Santos

SpaceX’s Starship Flight 6 launched today, missing a second capture landing for the Super Heavy first stage. However, it featured a dramatic daylight soft landing of the Starship second stage in the Indian Ocean—along with a banana. Today’s mission experienced an unusually smooth countdown for an experimental development flight, with the final hold skipped as

Scientists Alarmed by Unprecedented Coral Death in the Great Barrier Reef

Earth Science, Environmental Science / Jorge Paka

Australian research revealed on Tuesday that certain areas of the Great Barrier Reef have experienced the highest recorded coral mortality, with scientists concerned that other parts of the reef may have been affected in the same way. Coral Mortality and Environmental Stressors on the Great Barrier Reef However, the Australian Institute of Marine Science reported

Excessive Daytime Sleepiness May Indicate Early Signs of Dementia

Healthcare, Medicine / Jorge Paka

Older adults experiencing excessive daytime sleepiness or reduced motivation for daily tasks may be at higher risk of developing motoric cognitive risk (MCR), a pre-dementia condition that can lead to dementia. Daytime Sleepiness Linked to Early Signs of MCR These findings, from a new study by researchers at the Albert Einstein College of Medicine in

Evidence Reveals Your Body Can Inhale Vitamins from the Air

Healthcare, Medicine / Jorge Paka

That refreshing sensation you experience when breathing in fresh air in nature might involve more than just the absence of pollution. While we typically associate nutrients with our diet, a closer examination of scientific studies reveals compelling evidence that humans can also absorb certain nutrients directly from the air. In a recent perspective article in

Watch: First-Ever Nanoscale Video of Hydrogen and Oxygen Atoms Forming Water

Chemistry / Mauro Lucas

We all know the basic equation: hydrogen plus oxygen equals water. Now, scientists have taken it a step further, capturing the very first molecular-scale video of this iconic reaction. This breakthrough could ultimately pave the way for innovative methods to produce large quantities of drinking water. Palladium, a rare element, is a highly effective catalyst

Solar Still Made of Old Tires Purifies Water at Less Than 1c/Liter

Earth Science, Environmental Science / Eduardo Paulo

Canadian scientists have developed an innovative device that can purify a gallon of water per day for just a few cents. Even better, this sustainable purifier is made from recycled tires and can also generate small amounts of electricity. Innovative Solar Still Turns Undrinkable Water into Safe Drinking Water While Earth has abundant water, much
