This observation from NASA's Hubble Space Telescope, released on March 23, 2026, gives an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over the telescope's long lifetime.
Red-leaf lettuce is red due to anthocyanins, a class of polyphenolic pigments widely studied for their antioxidant properties. In plants, anthocyanins are synthesized through enzymatic reactions originating from the amino acid phenylalanine. Along this biosynthetic pathway,
Tens of kilometers above Earth's surface, high-energy particles from outer space constantly strike the atmosphere, creating showers of energetic secondary particles that rain down from the sky. Approximately one of these particles passes through your head every second, but the
Scientists from the Laboratory of Dermatological Photobiology of the University of Malaga, in collaboration with Cantabria Labs España, have carried out a study in which, for the first time, they have demonstrated how a natural extract—the Aspalathus linearis, the rooibos
Young children who spend more time on screen-based activities and less time talking with adults tend to have weaker language skills, according to a recent study from the University of Tartu. The findings highlight that daily interaction—rather than screen limits alone—plays a
A comprehensive new study extending the U.S. Historical Climatology Network (USHCN) record back to 1899 finds that both hot and cold temperature extremes across the contiguous United States have declined over the past 127 years. The research, performed by Dr. John R. Christy,
New research has revealed dairy calves that are fed less complete tasks faster and remember more in pursuit of milk, but miss out on play. Calves that were given more food were more inclined to play. The study, led by the University of Bristol and published in Scientific

A new species of coelacanth has been identified from a 150-year-old fossil housed at London's Natural History Museum. Former University of Portsmouth paleontology student Jack L. Norton located the coelacanth, which provides a crucial missing piece in the evolutionary history
About 30% of plastics consumed are made to last forever but are discarded after a single use. Researchers at Virginia Tech are working to change that with a new approach that could make environmentally responsible packaging more practical at scale.
Think of how many surfaces you touch every day, from your kitchen bench to the handrail on the bus or train, your work desk and your phone screen.
Millions of people around the world will pause Wednesday, at least for a moment, to mark Earth Day. It's an annual event founded by people who hoped to stir activism to clean up and preserve a planet that is now home to some 8 billion humans and assorted trillions of other
Most of Titan’s surface is oddly flat and smooth, and it may be because it is coated by as much as a metre of fluffy organic material that snowed down from the icy moon’s thick atmosphere
Antimicrobial resistance is becoming a global burden in human health and food production, so affordable new materials are needed to overcome this growing problem. To answer the call, a multidisciplinary research team led by Flinders University with U.K. experts has discovered a
The loss of our forests is one of the biggest environmental challenges of our time. Forests are key to curbing carbon emissions and protecting the plants, animals, and humans that call Earth home.
How far the Milky Way's disk extends has long been difficult to define—it doesn't end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of astronomers has identified the edge of the Milky Way's star-forming disk by studying the
An Iranian propaganda video depicts Donald Trump, Netanyahu and Satan as Lego figurines, the White House combines real footage of airstrikes with clips from films and video games, and the American president shares AI-generated videos of himself as a fighter pilot. It sounds
Researchers have developed a way to flip time to move backward in a quantum system. This level of control could lead to bizarre real-world applications
When supermarkets choose the right strategy for surplus food, they can both reduce food waste and improve their bottom line. An analysis from the University of Copenhagen shows that it is often more profitable to donate surplus food than to throw it away. In many cases, doing
Perovskite quantum dots are considered promising materials for LEDs, photocatalysis, and future quantum light sources. Researchers at LMU Munich have managed to master two major hurdles in working with these quantum dots: their stability in solution and precise control of their
Diamond is among the hardest naturally occurring substances on Earth, but if you shrink it down to the nanoscale, it is surprisingly elastic. And that could be useful for a host of applications such as quantum computing. In a paper published in the journal Physical Review X,
Some seemingly simple sequences of multiplication and addition grow so quickly that they question the very foundations of mathematics. In doing so, they demand a whole new level of logic
Following the recent successful test flight of NASA's Artemis II mission around the moon, NASA rolled out the core stage, or the largest section, of the agency's SLS (Space Launch System) rocket that will launch the crewed Artemis III mission in 2027. The stage departed from
A new gut microbiome study of bears in eastern North Carolina expands our understanding of microbial ecosystems in omnivores and contributes to the broader idea that bear feces could help scientists monitor changes in the environment. The study also found that bears may play an

More than 100 NASA astronauts have signed on to a nonpartisan effort to promote “the principles that have propelled our nation for 250 years”
Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an international team of astronomers has performed radio observations of FRB 20220912A—a highly active source of repeating fast radio bursts. Results of the monitoring campaign, published April 10 on the preprint
The extent of violence in England and Wales, especially against women, is obscured by official government statistics, a new study reveals. Researchers from Royal Holloway, University of London, and Lancaster University, have found that government statistics on violent crime
The Hubble Space Telescope turns 36 this year. And to celebrate, it released an incredible new image of the Trifid Nebula
Athletes say they hate to lose more than they love to win. New research finds the same sentiment is shared in organizations. A Virginia Tech researcher and his colleagues discovered that when managers frame work problems as a potential loss, employees are more likely to take
Superconductors, materials that can conduct electricity with a resistance of zero, have proved to be highly promising for the development of quantum technologies, medical imaging devices, particle accelerators and other advanced technologies. These materials can be divided into
