Ants may hold solution to human superbug, researchers discover

Has a crucial component to the development of human medicine been hiding under our feet? Auburn University Assistant Professor of Entomology Clint Penick and a team of graduate students may have found that ants are far ahead of humans in antibiotic innovation. “In our study, we tested how ants use antibiotic compounds to fight off pathogens and asked why their chemical defenses remain effective over evolutionary time,” Penick said.

“Humans have relied on antibiotics for less than a century, yet many pathogens have already evolved resistance, giving rise to ‘superbugs.’ Ants, by contrast, have been using antibiotics for tens of millions of years, and they might hold the key to using these powerful drugs more wisely.”

Ants as a source of antibiotics The team looked at just six ant species, all found easily in the Southeastern United States.

New memristor-based converter boosts energy efficiency in AI hardware

A cross-institutional team led by researchers from the Department of Electrical and Electronic Engineering (EEE), under the Faculty of Engineering at The University of Hong Kong (HKU), have achieved a major breakthrough in the field of artificial intelligence (AI) hardware by developing a new type of analog-to-digital converter (ADC) that uses innovative memristor technology. The work is published in Nature Communications.

Challenges with conventional AI hardware Conventional AI accelerators face challenges because the essential components that convert analog signals into digital form are often bulky and power-consuming. Led by Professor Ngai Wong, Professor Can Li and Dr. Zhengwu Liu of HKU EEE, in collaboration with researchers from Xidian University and the Hong Kong University of Science and Technology, the cross-disciplinary research team developed a new type of ADC that uses innovative memristor technology. This new converter can process signals more efficiently and accurately, paving the way for faster, more energy-efficient AI chips.

Adaptive system and efficiency gains The research team created an adaptive system that automatically adjusts its settings based on the data it receives, i.e., dynamically fine-tuning how signals are converted. This results in a 15.1× improvement in energy efficiency and a 12.9× reduction in circuit area compared with state-of-the-art solutions.

Noradrenergic control of bone marrow and thymus by AgRP neurons is impaired in experimental multiple sclerosis

In this work, Vigo et al. demonstrate that norepinephrine (NE) promotes myeloid hematopoiesis in BM and regulates thymic Tregs via B3ARs in EAE. B3ARs are controlled by hypothalamic AgRP neurons, which are dysfunctional in EAE. Serum levels of AgRP are elevated in people with MS and correlate with disease severity.

Cold weather concerns: Doctor explains how winter affects children’s immunity and growth

Winter’s chill impacts children’s health, increasing illness and affecting growth due to reduced sunlight, indoor confinement, and dietary shifts. Experts advise parents to prioritize balanced nutrition, adequate sleep, and physical activity. Simple measures like hygiene, vaccinations, and sun exposure are crucial for keeping kids healthy and thriving throughout the colder months.

Symptoms of a heart attack may emerge weeks beforehand: What to know

A heart attack is a medical emergency that requires an immediate call to the emergency services. However, there are sometimes warning signs that can show up weeks in advance that should prompt you to visit your doctor.

Firstly, what exactly happens during a heart attack? A heart attack occurs when the vessels that supply the heart itself with oxygen and nutrients—known as coronary arteries—become blocked. One cause is calcium deposits building up in them, says the German Heart Foundation.

As this is a gradual process, symptoms often appear before the blockage occurs, when the vessels are already narrowed in what is referred to as coronary heart disease.

Real-life experiment shows Niels Bohr was right in a theoretical debate with Einstein

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by Niels Bohr and his school of physicists. Bohr claimed there are properties of particles that cannot simultaneously be measured. The new result backs up the Copenhagen school yet again, with the potential to shed light on other, less settled questions in quantum mechanics.

When they met at physics conferences, Albert Einstein and Niels Bohr liked to kick back and debate about quantum mechanics. Einstein, always skeptical of the standard picture of quantum mechanics then being developed, liked to claim he had found holes and inconsistencies in Bohr’s interpretation, and Bohr was always up for the challenge.

At the 1927 Solvay conference in Brussels, the two Nobel Laureates had perhaps their most famous parley, with Einstein famously proclaiming, “God does not play dice with the universe.” In particular, Einstein proposed an experiment he thought would reveal the essential contradiction in the principle of complementarity, which held that pairs of properties of particles, such as position and momentum, and frequency and lifetime, cannot be measured at the same time. Complementarity undergirds the concepts of wave-particle duality and Heisenberg’s uncertainty principle.

NASA announcement for new lunar vehicle expected ‘in coming weeks,’ Colorado company 1 of 3 in consideration

WASHINGTON, DC (KOAA) — As NASA looks to return to the moon’s surface in the near future, Colorado company Lunar Outpost is one of three companies currently competing for a multi-billion dollar contract from the space agency for a new Lunar Terrain Vehicle (LTV).

On Monday, NASA indicated to KOAA the long-awaited decision could finally be made in the coming weeks of early 2026. NASA’s contract could have a combined maximum potential value of $4.6 billion for all awards.
