Many animals obtain information about others from scent marks left in the environment, including urine. Because these marks remain after the sender has left, they allow animals to communicate across space and time. But odor ...

Although increased cell proliferation is a hallmark of cancerous tissues, in some cases it may actually protect against tumor growth, according to a new study by Caltech researchers. Using mathematical models, the work suggests ...

Between 2021 and 2023, Antarctica appeared to be growing. Heavy snowfall fueled by wetter weather caused parts of the continent to gain mass, leading some to question whether climate change is really causing the ice to melt. ...

A new analysis of ice cores collected from the Andes in Peru has produced the first global record of historical tropical methane, filling a critical gap in our understanding of the origins of Earth's greenhouse gases.

Researchers at Nagoya University in Japan in collaboration with FUJIFILM have developed a novel way of delivering circular RNA (cirRNA) into cells, paving the way for longer-lasting mRNA-based therapeutics including cancer ...

Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids known to have beneficial effects and are popular as functional foods and dietary supplements. They are polyunsaturated fatty acids (PUFAs); ...

In the coming years, increasingly larger and more powerful quantum systems are expected to tackle problems that are difficult or impossible to solve using conventional computers. However, the more powerful quantum simulations ...

Niobium-94, an isotope of niobium with 41 protons and 53 neutrons, is a critical crossroads in the complex nuclear processes that forge heavy elements under the intense pressures and temperatures of dying stars. In an article ...

Archaeologists on Tuesday unveiled the skeletal remains of an adult they believe was buried as an offering near the base of Huaca Pucllana, an ancient adobe pyramid in Peru's capital of Lima.

Scientists have found evidence that a colossal cliff stretching thousands of kilometers across ancient North America may have exposed the heart of the Grand Canyon nearly a billion years before it was carved by the Colorado ...

Optical fibers are already the backbone of global communication systems. Recently, however, physicists have started to explore how their functionality could be boosted further by conveying information via entangled quantum ...

A team of researchers reports that they may have found rock containing some of the earliest forms of microbial life on Earth. Their study, published in the Proceedings of the National Academy of Sciences, describes the biosignatures ...
