Neuroscience Breakthrough: In-Vitro Neurons Exhibit Advanced Brain-Like Behavior

Posted by in categories: neuroscience, robotics/AI

Tohoku University scientists created lab-grown neural networks using microfluidic devices, mimicking natural brain activity and enabling advanced studies of learning and memory.

The phrase “Neurons that fire together, wire together” encapsulates the principle of neural plasticity in the human brain. However, neurons grown in a laboratory dish do not typically adhere to these rules. Instead, cultured neurons often form random, unstructured networks where all cells fire simultaneously, failing to mimic the organized and meaningful connections seen in a real brain. As a result, these in-vitro models provide only limited insights into how learning occurs in living systems.

What if, however, we could create in-vitro neurons that more closely replicate natural brain behavior?

Stretchable, Flexible, Recyclable: Princeton Scientists Develop Fantastic New Material

Posted by in categories: 3D printing, biotech/medical, chemistry, cyborgs, robotics/AI

Princeton engineers have developed a scalable 3D printing technique to produce soft plastics with customizable stretchiness and flexibility, while also being recyclable and cost-effective—qualities rarely combined in commercially available materials.

In a study published in Advanced Functional Materials, a team led by Emily Davidson detailed how they used thermoplastic elastomers—a class of widely available polymers—to create 3D-printed structures with adjustable stiffness. By designing the 3D printer’s print path, the engineers could program the plastic’s physical properties, allowing devices to stretch and flex in one direction while remaining rigid in another.

Scientists Warn: Synthetic “Mirror Life” Could Pose Unprecedented Risks

Posted by in category: biotech/medical

Researchers are warning of potential risks from the development of synthetic organisms called mirror bacteria, which have reversed molecular chirality.

These organisms could evade immune systems, disrupt natural ecosystems, and pose threats to human, animal, plant, and environmental health.

Mapping the Heliosphere: NASA’s Ambitious 2025 IMAP Mission Explained

Posted by in categories: mapping, space travel

NASA and SpaceX have rescheduled the launch of the IMAP spacecraft to September 2025 to allow more time for preparing its flight systems.

The mission will explore the heliosphere to understand the Sun’s protective bubble and its effects on space weather and life. Accompanying IMAP are two rideshare missions: the Carruthers Geocorona Observatory and NOAAs Space Weather Follow On – Lagrange 1, which will study Earth’s outer atmosphere and monitor solar activity, respectively. All three spacecraft will operate from Lagrange point 1 to efficiently monitor space conditions.

Stanford’s Vaccine Breakthrough Boosts Flu Protection Like Never Before

Posted by in categories: biotech/medical, innovation

Stanford Medicine researchers have developed a new method for influenza vaccination that encourages a robust immune response to all four common flu subtypes, potentially increasing the vaccine’s efficacy.

In laboratory tests using human tonsil organoids, the modified vaccine showed promising results in combating both seasonal and bird flu strains. The approach involves a combined antigen methodology that might also protect against emerging flu variants with pandemic potential.

Breakthrough in Pain Relief: Scientists Unveil a Safer, Non-Addictive Approach

Posted by in categories: biotech/medical, innovation

NUS researchers found that deuterated water (D₂O) reduces pain by modulating the TRPV1 ion channel, offering a non-addictive alternative to conventional painkillers.

Researchers from the National University of Singapore (NUS), in partnership with Peking University, China, have uncovered new insights into the TRPV1 (transient receptor potential vanilloid 1) ion channel and its role in pain perception. Their findings demonstrate how solvent molecules can influence pain signals, paving the way for potential development of safer, non-addictive pain management strategies.

Effective pain management is vital for improving quality of life and overall well-being. The TRPV1 ion channel, which plays a key role in detecting pain, expands its pore when activated, enabling ions and larger molecules to pass through. However, the ability of water molecules to permeate the TRPV1 channel has remained uncertain.

MAUVE: An Ultraviolet Astrophysics Probe Mission Concept

Posted by in categories: physics, space

For the past 30 years, NASA’s Great Observatories—the Hubble, Spitzer, Compton, and Chandra space telescopes—have revealed some amazing things about the universe. In addition to some of the deepest views of the universe provided by the Hubble Deep Fields campaign, these telescopes have provided insight into the unseen parts of the cosmos—i.e., in the infrared, gamma-ray, and ultraviolet spectrums.

With the success of these observatories and the James Webb Space Telescope (JWST), NASA is contemplating future missions that would reveal even more of the “unseen universe.”

This includes the UltraViolet Explorer (UVEX), a space telescope NASA plans to launch in 2030 as its next Astrophysics Medium-Class Explorer mission. In a recent study, a team led by researchers from the University of Michigan proposed another concept known as the Mission to Analyze the UltraViolet universE (MAUVE). This telescope and its sophisticated instruments were conceived during the inaugural NASA Astrophysics Mission Design School. According to the team’s paper, this mission would hypothetically be ready for launch by 2031.

Your Brain Flushes Out Waste Every Night… Here’s How To Help It Clean Up

Posted by in categories: biotech/medical, neuroscience

The glymphatic system becomes more active during sleep, especially during deep sleep, allowing for more effective waste clearance, said psychiatrist Dr. Jingduan Yang, founder of the Yang Institute of Integrative Medicine in Pennsylvania.

In a mouse study published in Science, researchers used tracers to monitor changes in cerebrospinal fluid flow. They found that during sleep, the interstitial, or intervening, space expanded by more than 60 percent, and the tracer influx increased. The brain’s clearance rate of beta-amyloid doubled during sleep (or under anesthesia) compared to the awake state.
