How did human culture become ecologically dominant? Morgan and Feldman re-examine existing theoretical accounts and propose that, contrary to previous belief, cumulative change and high transmission fidelity are not unique to human culture.
As quantum computing grows, researchers are urgently preparing for its impact on cybersecurity by developing quantum-resistant cryptographic protocols.
This research, led by experts at the National Center for Supercomputing Applications, focuses on safeguarding supercomputing infrastructures against quantum threats.

A 2023 epidemiological study revealed that 56% of a large Caspian tern breeding colony at Rat Island, Washington, succumbed to an outbreak of highly pathogenic avian influenza. Following this event, no birds have successfully bred on the island, heightening concerns about the outbreak’s potential impact on an already declining Pacific coast population.
As part of the study, a team including Washington Department of Fish and Wildlife (WDFW) as well as Washington State University researchers also documented that the avian flu virus H5N1was transmitted to harbor seals for the first time in the northeastern Pacific.
While there has not been another large coastal wildlife outbreak of H5N1 since, researchers estimated that about 10–14% of the Caspian tern population in the Pacific flyway have been lost to H5N1 infections.
A new technique enables data storage in synthetic polymers, allowing direct bit access without full sequence decoding, significantly increasing storage density and stability, demonstrated by encoding a university address in ASCII within a polymer.
The need for data storage is growing, with many types of data requiring long-term preservation. Synthetic polymers present an efficient alternative to traditional storage media, as they can store information using less space and energy. However, conventional retrieval methods, like mass spectrometry, limit the length—and therefore the storage capacity—of individual polymer chains. Now, as reported in Angewandte Chemie, researchers have developed a new approach that overcomes this limitation, enabling direct access to specific data bits without having to read the entire chain.
Advantages of polymer storage over DNA.
A trio of research papers from Stanford Medicine researchers and their international collaborators transforms scientists’ understanding of how small DNA circles — until recently dismissed as inconsequential — are major drivers of many types of human cancers.
The papers, published simultaneously in Nature on Nov. 6, detail the prevalence and prognostic impact of the circles, called ecDNA for extrachromosomal DNA, in nearly 15,000 human cancers; highlight a novel mode of inheritance that overthrows a fundamental law of genetics; and describe an anti-cancer therapy targeting the circles that is already in clinical trials.
The team, jointly known as eDyNAmiC, are a group of international experts led by professor of pathology Paul Mischel, MD. In 2022, Mischel and the eDyNAmiC team were awarded a $25 million grant from the Cancer Grand Challenges initiative to learn more about the circles. Cancer Grand Challenges, a research initiative co-founded by Cancer Research UK and the National Cancer Institute in the United States, supports a global community of interdisciplinary, world-class research teams to take on cancer’s toughest challenges.
New research indicates that people who contracted COVID-19 early in the pandemic faced a significantly elevated risk of heart attack, stroke, and death for up to three years post-infection.
Those with severe cases saw nearly quadruple the risk, especially in individuals with A, B, or AB blood types, while blood type O was associated with lower risk. This finding highlights long-term cardiovascular threats for COVID-19 patients and suggests that severe cases may need to be considered as a new cardiovascular risk factor. However, further studies on more diverse populations and vaccinated individuals are needed to validate these results.
Long-term cardiovascular risks linked to COVID-19 infection.
Scientists have created a compact spectral singlet lens that turns standard cameras into hyperspectral ones, reducing system size and complexity. This breakthrough could expand hyperspectral imaging into portable applications, with future improvements underway.
The information we gather shapes our understanding and perspectives of the world. For centuries, optics has sought to interpret the multidimensional data around us through the “toolbox” of light. In the 17th century, Sir Isaac Newton introduced the lens imaging formula and conducted his famous color spectrum experiment, laying foundational insights in the field.
Since then, lenses and spectrometers have been extensively studied as essential optical components for capturing information. Cascading these two components can allow us to acquire more information – both spatial and spectral data. However, such a configuration leads to tradeoffs among device footprint, spectral resolution, and imaging quality, impeding portability and miniaturization of hyperspectral cameras.
A breakthrough discovery in indium selenide could revolutionize memory storage technology by enabling crystalline-to-glass transitions with minimal energy.
Researchers found that this transformation can occur through mechanical shocks induced by continuous electric current, bypassing the energy-intensive melting and quenching process. This new approach reduces energy consumption by a billion times, potentially enabling more efficient data storage devices.

The threat actors behind the AndroxGh0st malware are now exploiting a broader set of security flaws impacting various internet-facing applications, while also deploying the Mozi botnet malware.
“This botnet utilizes remote code execution and credential-stealing methods to maintain persistent access, leveraging unpatched vulnerabilities to infiltrate critical infrastructures,” CloudSEK said in a new report.
AndroxGh0st is the name given to a Python-based cloud attack tool that’s known for its targeting of Laravel applications with the goal of sensitive data pertaining to services like Amazon Web Services (AWS), SendGrid, and Twilio.
