As Ebola rages, Moderna and others are racing to develop an mRNA vaccine for the rare Bundibugyo virus driving the current outbreak
What if some black holes aren’t black holes at all? A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the collapse could trigger the birth of a tiny new universe inside the dying star.
Millipedes may have been crawling across Earth's landscapes nearly 460 million years ago, long before vertebrates ventured onto land. A new study finally completes their evolutionary family tree, revealing surprising clues about these ancient ecosystem engineers and their early
A surprising new study suggests that completely eliminating sugar may backfire. Mice on a sucrose-free low-fat diet showed worse blood sugar control, increased inflammation, disrupted gut bacteria, and signs of fatty liver compared with mice that consumed some sucrose.
People taking popular weight-loss drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound may be losing pounds, but they could also be moving less. Researchers analyzing Fitbit data found that daily step counts and exercise levels dropped after people started these medications,
Parrots may be doing more than just repeating words—they may actually use names. By analyzing hundreds of recordings from pet parrots, researchers found evidence that many birds use specific names to identify particular people, animals, and even individual companions. Some
One of the most celebrated claims about Yellowstone’s wolves is facing a major challenge. Scientists say the study behind the famous trophic cascade story relied on flawed methods that overstated the ecological impact of wolf recovery. Their reanalysis found no evidence for a
When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them encounter manmade detectors. Recording how many of each of these elements show up
A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling
Ancient encounters between humans and the mysterious Denisovans are still shaping people today. By analyzing genomes from populations across the Pacific, researchers uncovered evidence that the ancestors of Near Oceanians interbred with at least three different Denisovan
Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected, opening a new radio astronomy frontier. A hydroxyl megamaser is a natural space laser, and this one is located in a violently merging galaxy more
Between the mid-1970s and early 1980s, two physicists, Michael Hart and Frank Tipler, published a controversial series of papers arguing that extraterrestrial intelligence didn't exist. As they argued, the likelihood that extraterrestrial civilizations (ETCs) would have had
The world relies on a modest number of countries to keep watch over the ocean. That arrangement is starting to fail. Europe and Asia must now decide whether to let the system unravel, or to take it up together.
UC researchers are investigating whether leaf protein and sugar extracted from plant fiber could help sustain people if major global shocks disrupt food production. Te Whare Wānanga o Waitaha | University of Canterbury (UC) Associate Professor David Denkenberger, who has spent
The same biological signals that help predict lifespan in humans also appear in dogs, according to new research from the Dog Aging Project—a finding that could help scientists better understand aging in both species.
Researchers at the Leibniz Centre for Agricultural Landscape Research have investigated how water from streams can be stored in the aquifer during wet periods. Using an area in the lower Spree catchment in Brandenburg as an example, the team used a computer model to show that
Physicists led by the University of Iowa have documented in the finest detail to date how energy from the sun interacts with Earth's magnetic field, which could yield greater insight into solar effects on Earth that drive space weather.
A new cellulose-based material platform developed in Finland responds to tightening regulatory requirements and industry pressure to both replace and reduce plastic in packaging, including emerging thresholds such as limiting plastic content to below 5 wt% in fiber-based
Pack enough string-like objects together, and they will begin to align with one another. But replace the strings with worms or bacteria living in your gut, and this self-organization becomes much more difficult. A team of University of Amsterdam (UvA) researchers has
Sarah Pappert is a Ph.D. candidate in astrophysics at the TUM School of Natural Sciences and conducts research at the Max Planck Institute for Extraterrestrial Physics. She is supervised by Prof. Dr. Reinhard Genzel and Prof. Dr. Frank Eisenhauer, who holds a TUM Distinguished
Previous research from the Centers for Disease Control and Prevention (CDC) found that a dangerous variety of bacteria that cause drug-resistant infections, called NDM-producing carbapenem-resistant Enterobacterales (NDM-CRE), has become much more common in the United States,
A new study has created a detailed map of the pituitary gland, often called the body's "master gland" because it controls important functions such as growth, stress and reproduction. Researchers from the Center for Craniofacial & Regenerative Biology combined data from many
In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that reactors cannot be covertly misused to produce materials for nuclear weapons.
A team of researchers has leveraged a supercomputer at the U.S. Department of Energy's (DOE) Argonne National Laboratory to reveal the internal structure of a pion in unprecedented detail. The findings are published in the Journal of High Energy Physics.
Hotter, drier conditions in the western United States have led to a rise in wildfire activity that has damaged or destroyed infrastructure, natural ecosystems and entire towns across the region. As fires grow larger and more destructive, the cost of managing them rises as well.
A new study challenges a long-standing assumption about how cyanobacteria survive environmental stress. The study, led by researchers at the Israel Oceanographic and Limnological Research (IOLR)—the Kinneret Limnological Institute (KLI), shows that survival under prolonged heat

Antimicrobial resistance (AMR) is considered one of the most urgent global public health threats, with experts predicting that AMR could cause 39 million deaths between 2025 and 2050. AMR is not a single problem, but instead involves many different genes, pathogens, hosts and
A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and
A newly identified crocodile species nicknamed “Lucy’s hunter” prowled Ethiopia’s rivers when Lucy’s species walked the Earth more than 3 million years ago. The giant predator was likely the most dangerous animal in the ecosystem and may have regularly hunted early human
Using NASA's Chandra X-ray spacecraft, astronomers have performed deep X-ray observations of a galactic globular cluster known as NGC 6540. The new observational campaign, described June 1 on the preprint server arXiv, focused on disentangling the nature of a peculiar X-ray
Globally, humanity now produces a staggering 450 million tonnes of plastic every year. From food and drink containers to cosmetics packaging, sewage pipes, window frames and polyester clothing, we use plastics in almost every area of life. And nearly one-quarter of them end up
It has long been understood that parents' income plays a major role in children's access to higher education. But a new study published in Canadian Studies in Population suggests that grandparents' income matters, too. By analyzing multigenerational tax data, researchers at
It's an insect everybody loves to hate. Pesky mosquitoes will be out in swarms as the weather warms up across the U.S.—and their bites aren't just itchy. They can transmit pathogens that can cause diseases like West Nile virus, Zika virus and malaria, to name a few.
Using the Keck Observatory, astronomers measured the spins of dozens of giant planets and brown dwarfs orbiting distant stars. They found that giant planets can spin faster than much more massive brown dwarfs, challenging simple assumptions about mass and rotation. The results
Headlines were made this week when scuba divers removing abandoned ghost nets from a shipwreck between Tunisia and Sicily filmed an adult great white shark. The footage quickly made global news, yet the real story is not that a great white was seen in the Mediterranean, but
Learning a musical instrument later in life may help keep the brain younger for longer. In a four-year study, older adults who continued practicing maintained their memory performance and showed less age-related brain shrinkage than those who quit. The benefits were especially
