A Robotic Sea Turtle Might Soon Be Gliding Through an Ocean Near You

When designing a fast, agile, and adaptable underwater robot, why not take inspiration from nature? That’s precisely what China’s Beatbot did with its bio-inspired Amphibious RoboTurtle. Unveiled as a prototype at CES last week, this autonomous robot is built for tasks like ecological research, environmental monitoring, and disaster response. Equipped for Advanced Exploration It can […]

Microscopic Fossilized Embryos Unveil Fascinating Insights into Life 500 Million Years Ago

Microbiology, Science / Mauro Lucas

Tiny mineralized spheres are offering fresh insights into the history of life on Earth. These millimeter-sized fossils, over 535 million years old, are the fossilized embryos of early Cambrian animals. Belonging to the Ecdysozoa group—which includes insects, spiders, crustaceans, and worms—the embryos present a fascinating mystery. While researchers cannot definitively identify their adult forms, Mingjin

An Impressive Robotic Hand Now has the Ability to Manipulate Objects it is Holding

Robotics, Science / Jorge Paka

Sanctuary AI’s Phoenix robot is undeniably remarkable, featuring hydraulically powered hands with exceptional dexterity. These hands have recently become even more versatile, as each can now simultaneously hold and manipulate an object. Typically, robotic fingers are operated using cables connected to electric motors. This setup is relatively straightforward, efficient, and cost-effective, provided the hand is

Streamlined Robotic Manta Ray Swims Faster with a Simplified, Efficient Design

Robotics, Science / Mauro Lucas

Just two years ago, a tiny robotic manta ray set a record as the fastest-swimming soft-bodied robot. Now, its upgraded successor has shattered that record while using less energy in the process. The original 22.8-mm-long robot was developed by Assoc. Prof. Jie Yin and his team at North Carolina State University. It featured two flexible

Parasites Unearthed in 500-Year-Old Toilet Expose Surprising Medieval Disease Networks

Microbiology / Mauro Lucas

The discovery of a 500-year-old African parasite in a Bruges latrine offers new insights into how medieval trade networks facilitated the spread of infectious diseases. Linked to Spanish merchants and global commerce, this finding sheds light on historical health challenges and human migration patterns. Published in Parasitology, the study uncovers one of the earliest known

Expert Identifies Irregular Brain Wave Patterns as Potential Indicator of ADHD

Neuroscience / Mauro Lucas

Children with attention deficit hyperactivity disorder (ADHD) are not lazy, undisciplined, or lacking manners. Instead, their brains develop and function differently, marked by unique neurological activity patterns and neurochemical imbalances. These differences classify ADHD as a neurodevelopmental disorder rather than a behavioral issue. The Neurological Basis of ADHD The neurological variations in ADHD manifest as

Adults Generate New Brain Cells, Which Play a Role in Enhancing Learning Through Listening

Neuroscience, Science / Mauro Lucas

Your brain can still produce new neurons in adulthood, but how do these rare additions support cognitive function? Neurons, the cells responsible for brain function, are mostly formed before birth. While early life sees the bulk of brain development, certain regions continue generating neurons into adulthood, albeit at a slower pace. Scientists debate whether adult

Smart Microscopes Reveals the Invisible on a Tablet-Sized Touchscreen

Microbiology / Mauro Lucas

Competitions like Nikon Small World reveal how much of the microscopic world remains unseen to the naked eye. Fortunately, affordable desktop microscopes, like BeaverLab’s Darwin MX Pro, now offer a window into these hidden realms for everyday users. BeaverLab, successful on crowdfunding platforms such as Indiegogo and Kickstarter, has introduced its latest model, the Darwin

Watch: Biomimetic Robo-Bird Takes Flight with a Leap

Robotics, Science / Mauro Lucas

While autonomous flying robots hold promising potential, their usefulness is limited if they cannot navigate uneven terrain after landing. However, an experimental bio-inspired robot overcomes this limitation by mimicking the raven’s gait. Named RAVEN (Robotic Avian-inspired Vehicle for Multiple Environments), the device was developed by Won Dong Shin and his team at Switzerland’s EPFL university.

Pandrug-Resistant Bacteria Emerging From the War in Ukraine are Highly Pathogenic

Microbiology, Science / Mauro Lucas

Kristian Riesbeck, a professor of clinical bacteriology at Lund University, was approached by Ukrainian microbiologist Oleksandr Nazarchuk for help in assessing antibiotic resistance in bacteria from severely injured, infected war patients. Using samples from 141 individuals, including 133 adults and 8 newborns with pneumonia, the study revealed widespread resistance to broad-spectrum antibiotics. Alarmingly, 6% of
