How Evolution Shaped the Brain’s Understanding of Numbers

Posted by in categories: biotech/medical, evolution, mathematics, neuroscience

Summary: Human number cognition may be rooted in the putamen, a deep brain structure traditionally associated with movement rather than abstract thought. Neurosurgery patients demonstrated activity in this area while processing numbers as symbols, words, and concepts, suggesting that numerical understanding emerged early in evolution.

Researchers also observed activity in expected areas like the parietal lobe, highlighting how different brain regions collaborate in number processing. These findings could improve surgical outcomes by protecting areas crucial for number cognition and open pathways to enhancing math learning through targeted interventions.

NASA Astronaut Captures Never-Before-Seen Image of Two Galaxies from SpaceX Capsule

Posted by in category: space travel

NASA astronaut Don Pettit captured a stunning long-exposure photograph of two nearby galaxies—the Large Magellanic Cloud and the Small Magellanic Cloud—from the SpaceX Crew Dragon capsule. This rare shot offers a unique view of these galaxies, located over 160,000 light-years away, visible only from space or the Southern Hemisphere.

Webb Uncovers Growing Galactic “City” in Spiderweb Cluster

Posted by in category: space

Astronomers using the James Webb Space Telescope have made significant discoveries within the Spiderweb protocluster, revealing the formation of new galaxies and challenging previous theories about gravitational interactions.

The infrared capabilities of Webb allowed for the observation of previously obscured galaxies, enhancing our understanding of galaxy assembly in one of the largest structures of the universe during its adolescent phase.

That Time A Particle Accelerator Helped Discover The Lost Works Of Archimedes

Posted by in categories: mathematics, particle physics, sustainability

It was 1,229 CE in the monastery of St Sabas, near Jerusalem, and a monk named Johannes Myronas was in need of some parchment. He had evidently been tasked with creating a copy of the Euchologion – an important book of prayer and worship directions for Eastern Orthodox and Byzantine Catholic churches.

The problem was, parchment was expensive and hard to come by. Recycling was the name of the game, and Johannes had just the thing: a 200-year-old manuscript filled with old math notes that nobody was all that interested in anymore. Compared with the Holy Word, there was no contest: he pulled it apart, scraped the old text off, and used the pages for the new book – a technique known as palimpsesting.

You probably know where this is going. In creating his Euchologion, Johannes had – presumably unwittingly – destroyed one of the most valuable relics of Archimedes’s work. Not just some notebook or single treatise, even: the manuscript now known as “Codex C” contained multiple works from the ancient polymath, some of which now exist nowhere else in the world.

Battery breakthrough extends EV range to over 3,000 miles on a single charge

Posted by in categories: energy, sustainability, transportation

In the fast-paced world of electric vehicles (EVs), a major breakthrough in battery technology is set to significantly enhance energy storage capacity. This development arrives at a crucial moment, as the EV industry is experiencing rapid growth, making it an ideal time for such a transformative advancement.

Researchers at Pohang University of Science & Technology (POSTECH) have introduced a revolutionary technique that can amplify the energy storage capacity of batteries by an astonishing tenfold. This leap forward not only propels battery technology to new heights but also has the potential to reshape the entire landscape of electric vehicles.

The key to understanding battery function lies in the anode, the component responsible for storing power during charging and then releasing it when the battery is in use. In most modern lithium batteries, graphite is the predominant material used for anodes.

Antiferromagnetic spin-torque diode effect in a kagome Weyl semimetal

Posted by in categories: computing, electronics

In a Mn3Sn/W epitaxial bilayer, spin–orbit torque induces the coherent rotation of spins, which can couple to microwave currents. Unlike in ferromagnets, the resulting conversion of AC current to DC voltage remains robust at higher frequencies, which may facilitate the development of high-speed electronic devices.

Next-Generation Size Selection for Optimized Long-Read Sequencing Workflow

Posted by in categories: biotech/medical, health, information science

All DNA is prone to fragmentation, whether it is derived from a biological matrix or created during gene synthesis; thus, any DNA sample will contain a range of fragment sizes. To really exploit the true benefits of long read sequencing, it is necessary to remove these shorter fragments, which might other wise be sequenced preferentially.

DNA size selection can exclude short fragments, maximizing data yields by ensuring that those fragments with the most informational content are not blocked from accessing detection centers (for example, ZMWs) by shorter DNA fragments.

Next-generation size-selection solutions Starting with clean, appropriate-length fragments for HiFi reads can accelerate research by reducing the computation and data processing time needed post-sequencing. Ranger Technology from Yourgene Health is a patent-protected process for automating electrophoresis-based DNA analysis and size selection. Its fluorescence machine vision system and image analysis algorithms provide real-time interpretation of the DNA separation process.
