Mitch Protein Identified as a Switch for Fat Burning and Fat-Cell Formation

Scientists have identified a protein called Mitch as a potential switch controlling both fat metabolism and the development of new fat cells. When the protein was switched off in human cells, the cells burned more fat and were less likely to form new fat cells. The discovery builds on experiments

Kikai Caldera Shows Signs of Magma Replenishment

Scientists using underwater seismic surveys have detected a vast magma reservoir beneath Kikai caldera, a submerged volcanic system south of Japan. The magma appears to have accumulated since one of Earth’s most powerful eruptions in recent geological history, which occurred about 7,300 years ago. The discovery indicates that

Nearly 3,000 Exploding Stars Point to a Changing Dark Energy

A large-scale analysis of 2,884 exploding stars has produced evidence that dark energy may not behave as a constant force over the universe’s history. Dark energy is the mysterious component associated with the accelerating expansion of the universe. The standard cosmological picture treats its behavior as consistent

Helion raises $225 million to advance fusion plant and semiconductor technology

Fusion energy startup Helion has secured $225 million in additional funding to accelerate development of its first fusion power plant. The plant is expected to provide electricity to Microsoft in 2028. Helion is also working on new semiconductor designs intended to double the output of its power plants, potentially improving

Unexpected temperature shift challenges models of Earth’s interior

A surprising temperature boundary deep within Earth Scientists studying a rock from Papua New Guinea have identified an unexpected temperature pattern at a depth of more than 90 kilometers beneath Earth’s surface. Rather than showing the conditions expected from established models of the planet’s interior, the rock indicates

North Sea Crater Linked to Asteroid Impact and Massive Tsunami

A decades-long mystery about the Silverpit Crater, a depression buried roughly 700 meters beneath the North Sea seabed, has been resolved. Scientists determined that the crater was formed when an asteroid approximately 160 meters wide struck Earth around 43–46 million years ago. The impact ejected a column of

Quantum Error Correction Hits Major Milestone With Demonstrations Beyond Breakeven

Quantum computing has taken a significant step forward with demonstrations of error correction that go well beyond the critical "breakeven" threshold—the point at which a logical qubit becomes more reliable than the best individual physical qubit it is built from. Error correction is essential for practical quantum
