The body you inhabit is made up of lots of moving parts that need to communicate with each other.
Some of this communication – in the nervous system, for example – takes the form of bioelectrical signals that propagate through the body to trigger the appropriate response.
Now, US researchers have discovered that the epithelial cells that line our skin and organs are able to signal the same way to communicate peril. They just use a long, slow ‘scream’, rather than the rapid-fire communication of neurons.
Researchers from Kyoto University have achieved a significant advancement in materials science by developing the world’s first three-dimensional van der Waals open frameworks (WaaFs). This innovation challenges the conventional belief that van der Waals interactions are too weak for open framework materials, demonstrating their potential for stable and highly porous materials.
Published in Nature Chemistry, the study presents a strategy using octahedral metal-organic polyhedra (MOPs) as building blocks to construct WaaFs. These frameworks exhibit high thermal stability, exceptional porosity, and reversible assembly, opening new avenues for applications in gas storage, separation, and catalysis.
WaaFs utilize van der Waals interactions, which were previously considered too weak, to form robust three-dimensional frameworks. These structures maintain their integrity at temperatures up to 593 K and achieve surface areas exceeding 2,000 m2/g, making them highly stable and efficient for various industrial applications.
Brain implants hold immense promise for restoring function in patients with paralysis, epilepsy and other neurological disorders. But a team of researchers at Case Western Reserve University has discovered that bacteria can invade the brain after a medical device is implanted, contributing to inflammation and reducing the device’s long-term effectiveness.
The research, published in Nature Communications, could improve the long-term success of brain implants now that a target has been identified to address.
“Understanding the role of bacteria in implant performance and brain health could revolutionize how these devices are designed and maintained,” said Jeff Capadona, Case Western Reserve’s vice provost for innovation, the Donnell Institute Professor of Biomedical Engineering and senior research career scientist at the Louis Stokes Cleveland VA Medical Center.
Researchers have enabled a man who is paralyzed to control a robotic arm through a device that relays signals from his brain to a computer.
He was able to grasp, move and drop objects just by imagining himself performing the actions.
The device, known as a brain-computer interface (BCI), worked for a record 7 months without needing to be adjusted. Until now, such devices have only worked for a day or two.
The BCI relies on an AI model that can adjust to the small changes that take place in the brain as a person repeats a movement – or in this case, an imagined movement – and learns to do it in a more refined way.
“This blending of learning between humans and AI is the next phase for these brain-computer interfaces,” said the neurologist. “It’s what we need to achieve sophisticated, lifelike function.”

Dr. Young’s leadership in diplomacy and innovation includes roles such as Senior Director of Science Policy at the Biden Cancer Initiative and Senior Science and Innovation Policy Advisor at the British Embassy, where she facilitated international agreements to enhance research collaborations.
New research from India has made it 10 times cheaper to construct buildings on-site using a 3D printer.
A report from The Better India highlights the work of Dr. Pradeepkumar Sundarraj, who built the Kelvin6K Pro. It’s India’s first on-site construction 3D printer that can build a 2,500-square-foot home in less than 30 days.
