By simulating early Earth conditions in the lab, researchers have found that without specific amino acids, ancient proteins would not have known how to evolve into everything alive on the planet today -- including plants, animals, and humans.

A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.

On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.

Researchers have demonstrated a switch, analogous to a transistor, made from a single molecule called fullerene. By using a carefully tuned laser pulse, the researchers are able to use fullerene to switch the path of an incoming electron in a predictable way. This switching process can be three to six orders of magnitude faster than switches in microchips, depending on the laser pulses used. Fullerene switches in a network could produce a computer beyond what is possible with electronic transistors, and they could also lead to unprecedented levels of resolution in microscopic imaging devices.

A new study explores 'balancing selection' by analyzing thousands of modern human genomes alongside ancient hominin groups, such as Neanderthal and Denisovan genomes. The research has 'implications for understanding human diversity, the origin of diseases, and biological trade-offs that may have shaped our evolution,' says evolutionary biologists.

Computer software can predict what happens to complex gene networks when individual genes are missing or dialed up more than usual. Mapping the roles of single genes in these networks is key to understanding healthy development and finding ways to regrow damaged cells and tissues. Understanding genetic errors could provide insight into birth defects, miscarriage or even cancer.

Along the shores of Africa's Lake Victoria in Kenya roughly 2.9 million years ago, early human ancestors used some of the oldest stone tools ever found to butcher hippos and pound plant material, according to new research. The study presents what are likely to be the oldest examples of a hugely important stone-age innovation known to scientists as the Oldowan toolkit, as well as the oldest evidence of hominins consuming very large animals. Excavations at the site, named Nyayanga and located on the Homa Peninsula in western Kenya, also produced a pair of massive molars belonging to the human species' close evolutionary relative Paranthropus. The teeth are the oldest fossilized Paranthropus remains yet found, and their presence at a site loaded with stone tools raises intriguing questions about which human ancestor made those tools.

Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.

New artificial intelligence technology being developed by engineers could significantly cut down on the time and cost that goes into film study for Super Bowl-bound teams (and all NFL and college football teams), while also enhancing game strategy by harnessing the power of big data.

Researchers have demonstrated that quantum bits (qubits) can directly transfer between quantum computer microchips and demonstrated this with record-breaking connection speed and accuracy. This breakthrough resolves a major challenge in building quantum computers large and powerful enough to tackle complex problems that are of critical importance to society.
