A Single Workout Can Improve Your Brain: Here’s What Scientists Found

Posted by in categories: health, neuroscience

UC Santa Barbara researchers discovered that single, vigorous exercise sessions, especially under 30 minutes, improve cognitive functions like memory and executive function. Future studies will explore whether combining physical activity with cognitive tasks yields even greater benefits.

Years of research on exercise have long supported the idea that consistent workouts over time lead to both physical and cognitive benefits. But what about short, intense bursts of exercise? A team of scientists at UC Santa Barbara has taken a closer look.

Their study was recently published in the journal Communications Psychology.

The Science Behind Inflammation’s Hidden Role in Depression

Posted by in categories: biotech/medical, neuroscience, science

New research underscores the role of the immune system in depression, linking inflammation to poor response to standard antidepressants and highlighting the importance of personalized medicine in addressing different biological patterns in depressed individuals.

A collaborative study between researchers from the UK and Italy has uncovered new insights into the biological mechanisms of major depressive disorder (MDD), with a particular focus on the role of the immune system.

The researchers examined “gene expression,” which refers to the process by which the instructions in our genes are activated, influencing bodily functions.

Berkeley’s Magic Material: Capturing Carbon From the Air Just Got Easier

Posted by in category: materials

Researchers at the University of California, Berkeley, have developed a new material for direct air capture that outperforms existing technologies.

This covalent organic framework (COF) can effectively remove carbon dioxide from ambient air, mimicking the absorptive capacity of trees but at a significantly accelerated rate.

Brain on Fire: The Mysterious Disease That Mimics Mental Illness

Posted by in categories: biotech/medical, neuroscience

Research reveals how antibodies affect brain receptors in patients with anti-NMDAR encephalitis, a condition often misdiagnosed as schizophrenia.

The disease, vividly described in Susannah Cahalan’s memoir “Brain on Fire,” can lead to severe neurological symptoms similar to those of mental health disorders. The study underscores the importance of personalized medicine and improved diagnostics to accurately treat and diagnose this rare disease.

Zero Resistance Breakthrough: Meet the Quantum Sandwich Powering the Future

Posted by in categories: computing, quantum physics

Researchers have developed a new “sandwich” structure material that exhibits the quantum anomalous Hall effect, enabling electrons to travel with almost no resistance at higher temperatures.

This breakthrough could significantly enhance computing power while dramatically reducing energy consumption. The structure is based on a layered approach with bismuth telluride and manganese bismuth telluride, promising faster and more efficient future electronic devices.

Genomic Advances Promise New Era for Early Disease Detection in Infants

Posted by in categories: biotech/medical, health

A new study shows that using DNA analysis for newborn screening can detect far more serious, yet treatable, health conditions than traditional methods. The study, called GUARDIAN, is one of the first large-scale projects to use genome sequencing for newborns, and early results suggest that this approach could greatly improve medical care for children.

Early findings from a study on newborn screening reveal that DNA analysis detects significantly more preventable or treatable serious health conditions than traditional screening methods. Most parents offered the option of genome sequencing prefer it.

The study, called GUARDIAN, is among the first large-scale research projects globally to use genome sequencing for newborn screening. It is also the first to release preliminary results.

Lithium Supply Crisis Averted: New Technology Doubles Extraction Efficiency

Posted by in categories: chemistry, sustainability

The demand for lithium, essential for powering sustainable technologies, is rising quickly, yet current methods leave up to 75% of the world’s lithium-rich saltwater sources inaccessible.

With some predicting global lithium supply could fall short of demand as early as 2025, the innovative technology – EDTA-aided loose nanofiltration (EALNF) – sets a new standard in lithium processing. The technology uniquely extracts both lithium and magnesium simultaneously, unlike traditional methods that treat magnesium salts as waste, making it smarter, faster and more sustainable.

The work, co-led by Dr Zhikao Li, from the Monash Suzhou Research Institute and the Department of Chemical and Biological Engineering, and Professor Xiwang Zhang from the University of Queensland, promises to meet the surging demand for lithium and paves the way for more sustainable and efficient extraction practices.

Pushchino multibeam pulsar search — V. The bright FRB 20190203 detected at 111 MHz

Posted by in category: space

Abstract: We report the discovery of a bright pulse having a dispersion measure (DM) equal to 134.4 \pm 2 pc cm^{-3}, a peak flux density (S_p) equal to 20 \pm 4 Jy and a half-width (W_e) equal to 211 \pm 6 ms. The excessive DM of the pulse, after taking into account the Milky Way contribution, is 114 pc cm^{-3} that indicates its extragalactic origin. Such value of DM corresponds to the luminosity distance 713 Mpc. The above parameters make the pulse to be a reliable candidate to the fast radio burst (FRB) event, and then it is the second FRB detected at such a large \lambda \sim 2.7 m wavelength and the first one among non-repeating FRBs. The normalized luminosity L_
u of the event, which we have designated as FRB 20,190,203, estimated under assumption that the whole excessive DM is determined by the intergalactic environment toward the host galaxy, is equal to \simeq 10^{34} erg s^{-1} Hz{-1}. In addition to the study of radio data we analyzed data from the quasi-simultaneous observations of the sky in the high energy (\ge 80 keV) band by the omnidirectional detector SPI/ACS aboard the INTEGRAL orbital observatory (in order to look for a possible gamma-ray counterpart of FRB 20190203). We did not detect any transient events exceeding the background at a statistically significant level. In the INTEGRAL archive, the FRB 20,190,203 localization region has been observed many times with a total exposure of \sim 73.2 days. We have analyzed the data but were unable to find any reliable short gamma-ray bursts from the FRB 20,190,203 position. Finally we note that the observed properties of FRB 20,190,203 can be reproduced well in the framework of a maser synchrotron model operating in the far reverse shock (at a distance of \sim 10^{15} cm) of a magnetar. However, triggering the burst requires a high conversion efficiency (at the level of 1%) of the shock wave energy into the radio emission.
