Cold War spy satellite imagery reveals Ancient Roman forts

A Dartmouth study analyzing declassified Cold War satellite imagery identified 396 previously undocumented Roman forts across the northern Fertile Crescent. The forts were constructed from east to west, contradicting Father Antoine Poidebard's north-south axis claim and suggesting a more complex distribution along Rome's eastern frontier.

The race of water droplets

A team of researchers from the University of Liège has studied the mechanisms governing water droplet speed along fibers. They found that thicker fibers result in lower speeds, but unexpected behavior occurs when two fibers are bundled together, leading to faster droplet movement.

Okinawa’s ants change their seasonal rhythms amid land-cover changes

Ant communities in Okinawa Island show reduced seasonal behavior in areas with more human development. Researchers found that ant populations in developed sites are less predictable and have diminished seasonality compared to forested areas. The study highlights the impact of human activities on insect populations and ecosystem services.

Easy diet changes can lower carbon footprint, according to Stanford Medicine-led study

Researchers identified simple food swaps that can make a big difference in an individual's carbon footprint without drastic dietary overhaul. The suggested changes include replacing beef with chicken or plant-based milk, which could reduce the nation's food-related carbon footprint by more than 35% and improve overall dietary quality.

Online games use dark designs to collect player data

A study by Aalto University reveals that online games employ deceptive data collection practices, often hiding information behind complex legal jargon. Players are often unaware of the risks and may feel compelled to conceal their identities or personal data to maintain privacy.

Meltwater flowing beneath Antarctic glaciers may be accelerating their retreat

New research suggests that meltwater flowing out to sea from beneath Antarctic glaciers is accelerating their retreat and contributing to global sea-level rise. The study's simulations indicate that this process could make a significant contribution to sea-level rise by 2300, potentially up to 15%.

Products made of plastic falsely claimed to be biodegradable are on sale at Brazilian supermarkets

Researchers found that most allegedly biodegradable plastic items sold by Brazilian supermarkets are actually oxo-degradable plastics banned in several countries. The products cost 125% more than conventional alternatives and failed to meet minimum requirements for genuine biodegradability.

Research group wins ERC Synergy grant for development of revolutionary colorectal cancer screening and treatment system

A research group led by Professor Kaspar Althoefer has been awarded a €10m ERC Synergy grant to develop a revolutionary new system for screening and treating colorectal cancer. The system, which combines medical robotics, artificial intelligence, and minimally invasive surgery, aims to improve patient outcomes and quality of life.

New quantum effect demonstrated for the first time: Spinaron, a rugby in a ball pit

Scientists at the University of Würzburg validated an alternate theory proposing the spinaron effect, where individual cobalt atoms exhibit perpetual motion and interact with electrons in a unique manner. This discovery could lead to breakthroughs in magnetic information encoding and transportation, making IT more energy-efficient.

Antibody-drug conjugate helps patients with metastatic non-small cell lung cancer live longer, delaying disease progression

A UCLA-led study shows datopotamab deruxtecan, a Trop-2 directed antibody-drug conjugate, significantly improves progression-free survival in patients with metastatic non-small cell lung cancer. The treatment primarily benefits patients with non-squamous tumors, reducing disease progression and improving overall survival.

A new era for accurate, rapid COVID-19 testing

Researchers at Osaka University have developed a novel platform that combines nanopore technology with artificial intelligence to detect different coronavirus variants quickly. The platform was tested on 241 saliva samples and detected the Omicron variant 100% of the time.

A safer alternative to CRISPR-Cas approaches?: Retroelement-based genome editing tools

Researchers propose retroelement-based gene editing as a safer alternative to CRISPR-Cas systems due to reduced risk of DNA double strand breaks and unwanted chromosomal modifications. This approach leverages endogenous mobile genetic elements, which can be programmed for targeted genomic engineering without generating DSB.

Does guideline-based treatment prevent racial disparities in cardiovascular outcomes?

Scientists find two ways that hurricanes rapidly intensify

New research identifies two modes of rapid intensification, one linked to favorable environmental conditions and warm surface waters, the other triggered by major bursts of thunderstorms far from the storm's center. These findings may lead to better understanding and prediction of catastrophic hurricanes.
