All Headlines
A vitamin A discovery is changing what scientists know about vision
A surprising discovery is reshaping scientists' understanding of how humans develop sharp central vision before birth. Instead of blue cone cells migrating away from the retina's center, the study found they transform into red and green cones under the influence of vitamin A-related signals and thyroid hormones. The findings could improve lab-grown retinal tissue and lay the groundwork for future cell therapies to restore vision lost to age-related eye diseases.
Trees keep absorbing carbon long after they stop growing
Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood production are not as closely linked as scientists once believed. The finding could reshape forecasts of how much carbon forests will be able to store in a warmer future.
Rare goblin shark filmed alive for the first time in the deep sea
For the first time, researchers have filmed the elusive goblin shark alive in the deep ocean where it naturally lives. The remarkable sightings greatly expand the shark's known range and depth, showing that this 125-million-year-old "living fossil" still has plenty of secrets left to reveal.
Harvard scientists turn a silicon chip into a DNA writing machine
Scientists have created a silicon chip that can write dozens of DNA sequences simultaneously using electricity and water-based enzymes, offering a cleaner alternative to conventional DNA manufacturing. The breakthrough could eventually support portable DNA-writing devices and even massive DNA data storage, although new chemistry will be needed to scale the technology further.
Heidelberg physicists just united two opposing quantum theories
A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter.
Scientists finally solved a 150-year-old gallium mystery
Scientists have rewritten the story of gallium after discovering that its unusual atomic bonds re-form at high temperatures, contradicting decades of accepted theory. The finding changes how researchers explain why the metal melts so easily and behaves unlike almost any other metal. Beyond solving a long-standing scientific mystery, the work could lead to advances in semiconductors, nanotechnology, and liquid metal engineering.
Ancient DNA reveals the mysterious collapse of Europe's megalith builders
DNA from a 5,000-year-old French megalithic tomb reveals that the people buried before and after a population collapse were genetically unrelated, pointing to a major migration after a devastating crisis. The shift coincided with new social traditions and the disappearance of the communities that built Europe's giant stone monuments.
This Mars rover could finally reveal whether life ever existed on Mars
The hunt for ancient life on Mars just got an important test run. Scientists confirmed that the Rosalind Franklin rover's sophisticated instrument can detect subtle differences in two stable molecules that could preserve evidence of past life for billions of years. But the team also uncovered a surprise: organic molecules in the Murchison meteorite appear to have been contaminated by fossil fuel pollution during their journey through Earth's atmosphere.
These ancient quasars shouldn't exist so soon after the Big Bang
Astronomers have uncovered 31 of the oldest known quasars, including the two earliest ever detected, shining from a time when the universe was only about 670 million years old. Powered by supermassive black holes billions of times the Sun’s mass, these incredibly bright objects challenge scientists’ understanding of how such enormous black holes formed so quickly after the Big Bang.
Scientists used AI to crack one of water's biggest mysteries
Water’s odd behavior becomes even more dramatic when it is supercooled, but scientists have struggled to compare the many different ways of describing its microscopic structure. Researchers at the University of Osaka used an AI model trained on computer simulations to evaluate 16 different structural descriptors. The system identified the most effective ways to distinguish between water’s two competing liquid states, providing a clearer framework for studying one of nature’s most mysterious subs
Incredible new material makes heat programmable
A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could lead to smarter infrared sensors, better energy technologies, and memory devices that use light and heat instead of electrical charges.
NASA's Hubble spots a stellar sparkler for the Fourth of July
NASA's Hubble Space Telescope has captured a spectacular red, white, and blue view of one of the Milky Way's oldest star clusters to celebrate the nation's 250th anniversary. Hidden within the ancient cluster are clues to how exploding stars helped transform the young universe into one capable of forming planets and, eventually, life.
