Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the…

A team of scientists dedicated to pinpointing the primordial origins of metabolism — a set of core chemical reactions that first powered life on Earth — has identified part of a protein that could provide scientists clues to detecting planets on the …

Recently, a research team resolved the contradiction between spatial resolution and imaging speed in optical microscopy. They achieved high-speed super-resolution by developing an effective technique termed temporal compressive super-resolution microsc…

The skeleton, tendons, and glands of a functional jaw all derive from the same population of stem cells, which arise from a cell population known as neural crest. To discover how these neural crest-derived cells know to make the right type of cell in t…

One in 10 adults suffer from the debilitating effects of chronic obstructive pulmonary disease (COPD). Research around a new breathing device developed by pulmonologists offers promise for improving their lives. The new device not only improves symptom…

Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. New research investigated the complex evolutionary history of jewel beetles’ vision.

Researchers have identified a new therapeutic target that could lead to more effective treatment of glaucoma.

When astrocyte function is disrupted, neurons in the brain’s motor cortex struggle to execute and refine motion, a new study in mice shows.

People with a third copy of chromosome 21, known as trisomy 21, are at high risk of developing acute myeloid leukemia (AML), an aggressive form of blood cancer. Scientists have now identified the cause: although the additional chromosome 21 leads to in…

Decades of poor environmental and water management turned the Nile River Delta from a unique ecological habitat in the Sahara to one of the largest polluted areas on the planet, with tens of millions of people and migrating birds at risk of exposure to…

New evidence shows that exceeding the World Health Organization (WHO) ozone limit is associated with substantial increases in hospital admissions for heart attack, heart failure and stroke. Even ozone levels below the WHO maximum were linked with worse…

A newly developed molecular catalyst specifically tailored for mechanochemical reaction conditions enables high-efficiency transformations at near room temperature.

Researchers have discovered that softer gums hinder the development of gingiva fibroblasts — the cells that help produce the fibers that hold our teeth in place.

Fluorescence is a fascinating natural phenomenon. It is based on the fact that certain materials can absorb light of a certain wavelength and then emit light of a different wavelength. Fluorescent materials play an important role in our everyday lives,…

An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
