Psychopaths have a 10% larger striatum than non-psychopaths, suggesting biological differences in brain structure. This enlargement is tied to impulsivity and a higher craving for stimulation.
The discovery, seen in both men and women, points to psychopathy’s roots in neurodevelopment. It could lead to better understanding and interventions for antisocial behavior.
Brain scans reveal key difference in psychopaths.
Mushrooms are known for their toughness and unusual biological properties, qualities that make them attractive for bioelectronics. This emerging field blends biology and technology to design innovative, sustainable materials for future computing systems.
Turning Mushrooms Into Living Memory Devices
Researchers at The Ohio State University recently discovered that edible fungi, such as shiitake mushrooms, can be cultivated and guided to function as organic memristors. These components act like memory cells that retain information about previous electrical states.
I first explored this amazing work back when it was a preprint! Wang et al. herein developed VIPS (volumetric imaging via photochemical sectioning), a way of using UV light to remove layers of expanded tissue-hydrogel, allowing combination of high-resolution lattice-light sheet microscopy with expansion microscopy.

In my opinion, this technology has enormous future promise for high-throughput connectomics! They will need to improve their labeling density so that higher expansion factors can be used, but this problem is well-studied and I think the issue will likely be solvable with additional resources/effort.
Optical nanoscopy of intact biological specimens has been transformed by recent advancements in hydrogel-based tissue clearing and expansion, enabling the imaging of cellular and subcellular structures with molecular contrast. However, existing high-resolution fluorescence microscopes are physically limited by objective-to-specimen distance, which prevents the study of whole-mount specimens without physical sectioning. To address this challenge, we developed a photochemical strategy for spatially precise sectioning of specimens. By combining serial photochemical sectioning with lattice light-sheet imaging and petabyte-scale computation, we imaged and reconstructed axons and myelin sheaths across entire mouse olfactory bulbs at nanoscale resolution.
In this video, we explore one of the most fascinating frontiers of technology — merging humans and machines through soundwaves. Discover how scientists are using acoustic signals to transmit data, control implants, and even connect the human brain to AI systems — all without wires. From ultrasonic communication to sound-based neural interfaces, this is where biology meets next-gen tech. Watch till the end to see how this breakthrough could redefine human evolution!
A new study has revealed how phosphorus, a nutrient essential for photosynthesis, surged into ancient oceans and started Earth’s first major rise in atmospheric oxygen more than 2 billion years ago.
Dr. Matthew Dodd, from UWA’s School of Earth and Oceans, is lead author of the study published in Nature Communications. “By fueling blooms of photosynthetic microbes, these phosphorus pulses boosted organic carbon burial and allowed oxygen to accumulate in the air, a turning point that ultimately made complex life possible,” Dr. Dodd said.
The research combined a global archive of ancient carbonate rocks with modeling to simulate Earth’s climate system and show that ocean phosphorus and atmospheric oxygen rose and fell together during the Great Oxidation Event.
Photo-induced force microscopy began as a concept in the mind of Kumar Wickramasinghe when he was employed by IBM in the early years of the new millennium. After he came to the University of California, Irvine in 2006, the concept evolved into an invention that would revolutionize research by enabling scientists to study the fundamental characteristics of matter at nanoscale resolution.
Since the earliest experimental uses of PiFM around 2010, the device, which reveals the chemical composition and spatial organization of materials at the molecular level, has become a tool of choice for researchers in fields as diverse as biology, geology, materials science and even advanced electronics manufacturing.
“This is the story of a technology that was inspired by work at IBM, was invented and developed at UC Irvine, then got spun off, and now we have instruments on all continents across the world except for Antarctica,” says Wickramasinghe, Henry Samueli Endowed Chair and Distinguished Professor emeritus of electrical engineering and computer science who now holds the title of UC Irvine Distinguished Research Professor. “Almost anywhere serious research is happening, there are people out there who are using PiFM to discover new things.”
Imagine the magnificent glaciers of Greenland, the eternal snow of the Tibetan high mountains, and the permanently ice-cold groundwater in Finland. As cold and beautiful as these are, for the structural biologist Kirill Kovalev, they are more importantly home to unusual molecules that could control brain cells’ activity.
Kovalev, EIPOD Postdoctoral Fellow at EMBL Hamburg’s Schneider Group and EMBL-EBI’s Bateman Group, is a physicist passionate about solving biological problems. He is particularly hooked by rhodopsins, a group of colorful proteins that enable aquatic microorganisms to harness sunlight for energy.
“In my work, I search for unusual rhodopsins and try to understand what they do,” said Kovalev. “Such molecules could have undiscovered functions that we could benefit from.”
Because oxygen-bearing sulfate minerals trap and preserve signals from Earth’s atmosphere, scientists closely study how they form. Sulfates are stable over billions of years, so their oxygen isotopes are seen as a time capsule, reflecting atmospheric conditions while they were evolving on early Earth—and possibly on its planetary neighbor Mars.
A new study led by a University of Utah geochemist examines how sulfate forms when pyrite, commonly known as “fool’s gold,” is oxidized in environments teeming with microbes versus those without them. The researchers focused on Spain’s Rio Tinto, a contaminated river passing through a region where iron and copper were mined for thousands of years.
The paper titled, “Triple-oxygen isotopic evidence of prolonged direct bioleaching of pyrite with O2,” appears in Earth and Planetary Science Letters.
