Obesity increases the body's need for insulin, forcing cells in the pancreas known as beta cells to ramp up insulin production to maintain blood sugar levels. Scientists have thought that this excessive insulin secretion ...

Scientists from the University of Manchester have played a leading role in the discovery of a new subatomic particle at CERN's Large Hadron Collider (LHC). The particle, known as the Ξcc⁺ (Xi‑cc‑plus), is a new type ...

Cells rely on tiny molecules called microRNAs to tune which genes are active and when. Cells must carefully control the lifespan of microRNAs to prevent widespread disruption to gene regulation. A new study led by researchers ...

Beavers could engineer riverbeds into promising carbon dioxide sinks, according to a new international study led by researchers at the University of Birmingham. The paper, published in Communications Earth & Environment, ...

Sheepdogs, bred to control large groups of sheep in open fields, have demonstrated their skills in competitions dating back to the 1870s. In these contests, a handler directs a trained dog with whistle signals to guide a ...

Cancer-fighting T cells do not simply "run out of energy." They are molecularly reprogrammed. For years, mitochondrial dysfunction has been recognized as a hallmark of exhausted T cells in tumors. Yet how metabolic stress ...

Researchers at Rensselaer Polytechnic Institute (RPI) have created a new and unusual state of matter—known as a supersolid—by engineering how light and matter interact inside a nanoscale device. The work, published in ...

Climate change is one of the most pressing global challenges in the present times. Increasing carbon dioxide (CO2) concentrations in the atmosphere are a major factor contributing to this phenomenon. Activities such as the ...

The rocks beneath our feet are leaving a hidden signature in the shells of marine snails along Australia's ancient coastline, according to new research led by Adelaide University scientists. A study published in Proceedings ...

Proteins, one of the smallest building blocks of life on Earth, hold promise for answering some of biology's biggest questions. Consisting of amino acids strung together into peptide chains, these molecules perform much of ...

For more than a century, heparin has been the go-to anticoagulant to prevent harmful blood clots in blood vessels or the heart from forming or getting larger. However, a major side effect is an increased risk of excessive ...

For over 350 years, quinine and other extracts from the cinchona tree (Cinchona spp.) were the only effective medicines against malaria, a tropical fever caused by single-celled parasites of the genus Plasmodium and transmitted ...
