Agriculture is driving rapid evolutionary change, not just on farms but also in wild species in surrounding landscapes, new research has found.

Devastating megafires are becoming more common, in part, because the planet is warming. But a new study suggests bringing 'good fire' back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today's wildfires.

For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.

Extracting ancient DNA from teeth, an international group of scientists peered into the lives of a once-thriving medieval Ashkenazi Jewish community in Erfurt, Germany. The findings show that the Erfurt Jewish community was more genetically diverse than modern day Ashkenazi Jews.

A new article discusses vital methodological issues for humanities-based historical inquiry and argues that the challenges of the Anthropocene demand interdisciplinary research informed by a variety of historical narratives.

A team of researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.

A new study has found that organelle-like transcriptional condensates are an ancient and flexible tool used by cells to drive rapid gene expression.

With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.

The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.

The remains of a huge carp fish mark the earliest signs of cooking by prehistoric human to 780,000 years ago, predating the available data by some 600,000 years, according to researchers.

Privacy experts have created an AI algorithm that automatically tests privacy-preserving systems for potential data leaks.

Computer scientists have succeeded in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer. They have developed a systematic method that applies optimal control theory (GRAPE algorithm) to identify the theoretically optimal sequence from among all conceivable quantum operation sequences. This method is expected to become a useful tool for medium-scale quantum computers and is expected to contribute to improving the performance of quantum computers and reducing environmental impact in the near future.

Scientists have developed a mathematical description of what happens within tiny magnets as they fluctuate between states when an electric current and magnetic field are applied. Their findings could act as the foundation for engineering more advanced computers that can quantify uncertainty while interpreting complex data.

Researchers have shown that a component of modern computer processors that enables different areas of the chip to communicate with each other is susceptible to a side-channel attack. An attacker can monitor how traffic from two different cores on a processor interferes with each other to extract secret information, like a cryptographic key.

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.

An international team has successfully implemented an advanced form of quantum cryptography for the first time. Moreover, encryption is independent of the quantum device used and therefore even more secure against hacking attempts.

Many people and companies worry about sensitive data getting hacked, so encrypting files with digital keys has become more commonplace. Now, researchers have developed a durable molecular encryption key from sequence-defined polymers that are built and deconstructed in a sequential way. They hid their molecular key in the ink of a letter, which was mailed and then used to decrypt a file with text from a classic story.

Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the trick.

While quantum computers offer many novel possibilities, they also pose a threat to internet security since these supercomputers make common encryption methods vulnerable. Based on the so-called quantum key distribution, researchers have developed a new, tap-proof communication network.

A laser pulse that sidesteps the inherent symmetry of light waves could manipulate quantum information, potentially bringing us closer to room temperature quantum computing.
