Robots Trained on Spatial Datasets Gain Better Awareness and Object Handling

Machines naturally lag behind humans in navigating their environments. To strengthen the visual perception skills robots need to interpret the world, researchers have created a new training dataset designed to boost their spatial awareness. RoboSpatial Boosts Robots’ Spatial Awareness In recent work, experiments revealed that robots trained on the new dataset, RoboSpatial, surpassed those using […]

IQ May Affect How Well You Understand Speech

Healthcare, Mental / Ngoma Manuel

Sometimes scientific findings reveal connections that seem surprising at first but become more understandable on closer consideration—such as a correlation between lower IQ and difficulty following conversations in noisy settings. Previous research has shown that neurodiverse individuals may struggle more than others to hear speech in noisy environments. To explore this further, a team of

The Neurotechnology Revolution: What Once Was Sci-Fi Is Now Real

Neuroscience, Science / Ana Kiesse Zeleme

Advancing from converting thoughts into speech to enabling paralyzed individuals to walk, neurotechnology has been steadily progressing, sparking hopes for medical innovations as well as significant ethical questions. Some experts believe that neurotechnology could become as transformative as the widely discussed surge of artificial intelligence (AI). “Many people don’t realize how much of our lives

A Modular Robot that Becomes one Quad or Two Bipeds — your Choice

Applied Science, Robotics / Ana Manuel

These days, quadruped robots with powered wheels for feet aren’t uncommon, letting them walk or roll depending on the terrain. The modular D1 stands out by functioning as either a quadruped or two independent bipeds. Traditional quadrupeds handle rough terrain well, stepping over obstacles and climbing stairs while keeping four points of contact for stability.

Why Your Brain Struggles to Concentrate When you’re Sleep-Deprived

Applied Science, Neuroscience / Jorge Paka

Sleep isn’t just downtime — it’s a vital biological function that keeps your mind sharp, your thoughts focused, and your reflexes quick. Yet in today’s fast-moving world, skipping sleep has become routine, even though our bodies depend on it as much as they do on oxygen. A restless night can derail your brain’s repair cycle,

Scientists Recreate Rare Pigment Behind Octopus’s Abilities

Plants & Animals, Science / Ana Kiesse Zeleme

Octopuses and other cephalopods are renowned for their remarkable camouflage abilities, using color-shifting skin to blend seamlessly into their surroundings. Now, scientists have made significant progress toward replicating this natural talent. UCSD Engineers Bacteria to Mass-Produce Cephalopod Pigment A UC San Diego–led research team has succeeded in mass-producing xanthommatin — a key pigment found in

A Grain-sized Wireless Brain Implant Fires Lasers

Applied Science, Neuroscience / Jorge Paka

If you have a brain—and know others who do—you’re aware of the countless ways our skull-bound electro-meat machines can fail us. From memory loss to migraines, depression to dementia, the brain is remarkably creative at breaking down, often turning lives into mental misery. “Good news, everyone!” Cornell and partners developed a pinhead-sized micro-neural implant that

‘Brainless’ Robots That Move Together are Driven Entirely By Air

Applied Science, Robotics / Eduardo Paulo

Researchers at the University of Oxford have created a new type of soft robot that functions without electronics, motors, or computers, relying solely on air pressure. Published in Advanced Materials, the study demonstrates that these “fluidic robots” can produce complex, rhythmic motions and even synchronize their movements automatically. Professor Antonio Forte (Department of Engineering Science,

A light-Controlled Flexible Lens may Give Soft Machines Vision

Healthcare, Medicine / Jorge Paka

Inspired by the human eye, our biomedical engineering team at Georgia Tech has developed an adaptive lens made from soft, light-sensitive materials. Traditional adjustable cameras rely on bulky, rigid lenses and a pupil to control focus and brightness. In contrast, the human eye achieves this through soft, flexible tissues in a compact design. A Soft,

Magnetic Gel May Offer a more Efficient Way To Eliminate Kidney Stones

Healthcare, Medicine / Ana Kiesse Zeleme

Stanford University has introduced a ureteroscopy-friendly device that uses a wire to magnetically capture and remove kidney stone fragments, demonstrating superior results compared to conventional methods in a pig model. Kidney stone disease impacts roughly 11% of people in the U.S. and frequently necessitates ureteroscopic laser lithotripsy. Removing fragments after lithotripsy is often inefficient, leaving
