Researchers used D-Wave’s quantum computing technology to explore the relationship between prefrontal brain activity and academic achievement, particularly focusing on the College Scholastic Ability Test (CSAT) scores in South Korea.

The study, published by a multi-institutional team of researchers across Korea in Scientific Reports, relied on functional near-infrared spectroscopy (fNIRS) to measure brain signals during various cognitive tasks and then applied a quantum annealing algorithm to identify patterns correlating with higher academic performance.

Solar power at US schools surges, growing fourfold over the last decade

Posted by in categories: education, solar power, sustainability

Since 2014, solar capacity at K-12 schools has more than quadrupled across the US, according to a new report from clean energy nonprofit Generation180.

The “Brighter Future: A Study of Solar on K-12 Schools” report highlights that over 6.2 million students – more than 1 in 9 – now attend schools powered by solar. In 2023 alone, more than 800 schools added solar panels, meaning that at least one school went solar every single day during the 2022–23 school year.

“The benefits of solar energy are now reaching a broad range of schools across the country, including those in under-resourced communities that stand to gain the most from the cost savings and educational opportunities that solar technology provides. We want all schools and communities, regardless of their size, geography, or wealth, to have access to affordable, clean energy,” says Tish Tablan, the report’s lead author and senior director of Generation180’s Electrify Our Schools Program.

New technique shows promise for mass fabricating an exotic quasi-1D material

Posted by in categories: computing, nanotechnology, quantum physics

Researchers have fabricated a quasi-one-dimensional van der Waals zirconium telluride thin film, which is a form of a substance that has long promised advances in quantum computing, nano-electronics and other advanced technologies. Until now, it has stumped scientists who have tried to manufacture it in large-scale quantities.

Rare Milky Way star cluster is packed with red supergiants 1 million times brighter than the sun

Posted by in categories: energy, space

“There are many open clusters in the galaxy. However, not all open clusters have the same level of interest to astronomers,” Ignacio Negueruela, a researcher at the Universidad de Alicante who was part of the team behind the discovery of supergiants in Barbá 2, told Space.com. “Clusters rich in red supergiants are very rare and tend to be very far away, but they play a crucial role in understanding key aspects in the evolution of massive stars.”

The intimidating size and power of supergiants means these monster stars burn through their nuclear fuel much faster than stars like the sun. Whereas our star will exist in its main sequence lifetime for around 10 billion years, supergiants are estimated to last just a few million years.

The short lifetime of supergiants means that while open clusters like Barbá 2 are common, with over 1,100 already discovered in the Milky Way alone, finding one packed with red supergiants is extremely rare.

NASA’s Moon Launcher Is in Big Trouble

Posted by in categories: internet, space

Reports that each of NASA’s Artemis launches could cost as much as $4.1 billion…


“Costs going up faster than the tower,” self-described internet rocket scientist Scott Manley joked at the time.

NASA used its Mobile Launcher 1 for its inaugural — albeit uncrewed — Artemis mission in late 2022. According to a 2020 audit, the tower, which was originally built for NASA’s canceled Constellation program, cost $234 million to develop.

Ketogenic Diet may Reduce Friendly Gut Bacteria and raise cholesterol levels

Posted by in categories: biotech/medical, food, health

Published in Cell Reports Medicine, the research from the Centre for Nutrition, Exercise, and Metabolism involved 53 healthy adults for up to 12 weeks. Participants followed either a moderate sugar diet (control), a low-sugar diet (less than 5% of calories from sugar), or a ketogenic (keto) low-carbohydrate diet (less than 8% of calories from carbohydrates).

Key findings include:

Increased Cholesterol: The keto diet raised cholesterol levels, particularly in small and medium sized LDL particles. The diet increased apolipoproteinB (apoB), which causes plaque buildup in arteries. In contrast, the low-sugar diet significantly reduced cholesterol in LDL particles.

Astronomers Uncover Risks to Planets that could Host Life

Posted by in categories: alien life, computing

A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed. This discovery suggests that the intense UV radiation from these flares could significantly impact whether planets around red dwarf stars can be habitable. Led by current and former astronomers from the University of Hawaii Institute for Astronomy (IfA), the research was recently published in the Monthly Notices of the Royal Astronomical Society.

“Few stars have been thought to generate enough UV radiation through flares to impact planet habitability. Our findings show that many more stars may have this capability,” said astronomer Vera Berger, who undertook the study while in the Research Experiences for Undergraduates program at IfA, an initiative supported by the National Science Foundation.

Berger and her team used archival data from the GALEX space telescope to search for flares among 300,000 nearby stars. GALEX is a now-decommissioned NASA mission that simultaneously observed most of the sky at near-and far-UV wavelengths from 2003 to 2013. Using new computational techniques, the team mined novel insights from the data.
