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

Microbiology /

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 /

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 /

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 /

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 /

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 /

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

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

Robotics, Science /

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

A Robotic Model Equipped with Real Pigeon Feathers Mimics Bird Flight

Robotics, Science /

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

RoBoa Slinks Through Disaster Areas that are Too Perilous for Other Robots

Robotics, Science /

When disaster strikes, drones and robots can search for survivors in dangerous zones. The student team at ETH Zurich designed the RoBoa to slither through debris that would stop other robots. Developed at the Autonomous Systems Lab, RoBoa aids rescue teams in disaster and war zones. Its snake-like movement allows it to navigate rubble while

Watch: Ambitious Robot Learn Show to Clean a Bathroom Sink by Observing

Robotics, Science /

From washing urinals to tidying beaches, the idea of robots helping keep our world cleaner is already becoming a reality. Now, a robot arm has successfully tackled the surprisingly intricate task of washing a sink, demonstrating its ability to learn on its own. While cleaning a wash basin might seem like a simple chore, there’s
