	Bacterium discovered in the Amazon is closely related to Andean species that causes human bartonellosis A new species of bacteria of the genus Bartonella has been found in the Amazon National Park in the state of Pará, Brazil, in phlebotomine insects, also known as sand flies. This type of insect is generally associated with transmitting leishmaniasis, but according to the researchers, the DNA of the newly discovered microorganism is similar to that of two other Andean species of bacteria, B. bacilliformis and B. ancashensis. These bacteria cause Carrión's disease (also known as Peruvian wart and Oroya fever) and are both transmitted by phlebotomine sand flies.
	Clinical trial shows constipation drug can treat patients with chronic kidney disease Chronic kidney disease (CKD) is a major health issue worldwide. Many patients end up requiring regular dialysis to avoid kidney failure and stay alive. Despite the severity of the condition, there are currently no drugs available that improve kidney function.
	First enzyme-targeting drug reverses damage in metabolic fatty liver disease Researchers at the University of California San Diego School of Medicine have identified a new investigational drug that shows promise in treating metabolic dysfunction-associated steatohepatitis (MASH), a serious form of fatty liver disease linked to obesity and type 2 diabetes that can lead to cirrhosis, liver failure, and even liver cancer.
	Telling the story of the Atlantic's sargassum surge with 40 years of data Researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute have released a landmark review tracing four decades of changes in pelagic sargassum—free-floating brown seaweed that plays a vital role in the Atlantic Ocean ecosystem.
	Rising deep-ocean oxygen levels likely opened up new marine habitats and spurred speciation Some 390 million years ago in the ancient ocean, marine animals began colonizing depths previously uninhabited. New research indicates this underwater migration occurred in response to a permanent increase in deep-ocean oxygen, driven by the above-ground spread of woody plants—precursors to Earth's first forests.
	When bison have room to roam, they reawaken the Yellowstone ecosystem Scientists from Washington and Lee University, the National Park Service and the University of Wyoming have published research in Science shedding new light on the value of bison recovery efforts in Yellowstone National Park.
	100-million-year-old pearl fossil found in ancient seabed in Australian outback Over 100 million years ago, long before the extinction of land-dwelling dinosaurs, there lived a group of massive clams called Inoceramus.
	Probability theorem gets quantum makeover after 250 years How likely you think something is to happen depends on what you already believe about the circumstances. That is the simple concept behind Bayes' rule, an approach to calculating probabilities, first proposed in 1763. Now, an international team of researchers has shown how Bayes' rule operates in the quantum world.
	Stubborn high blood pressure drops with an experimental drug that targets hormone imbalance A new treatment has been shown to significantly lower blood pressure in people whose levels stay dangerously high, despite taking several existing medicines, according to the results of a Phase III clinical trial led by a UCL Professor.
	'Perfect storm': UK fishermen reel from octopus invasion When veteran fisherman Brian Tapper checked his 1,200 crab pots in waters off southwest England during this year's crabbing season, he got a series of unwelcome surprises.
	When crowds left, reefs came alive at Hanauma Bay Hanauma Bay Nature Preserve, a popular snorkeling destination that attracts nearly a million annual visitors, underwent a remarkable and rapid recovery when tourism ceased during the 2020 COVID-19 pandemic.
	Mental time travel: A new case of autobiographical hypermnesia Remembering past events in minute detail, revisiting them methodically, and reliving past emotions—this is the peculiarity of people with an exceptional memory of their own lives, known as autobiographical hypermnesia, or hyperthymesia. This fascinating condition remains poorly understood, and each new case contributes to our understanding.
	Mammoth DNA from Mexico reveals a divergent lineage Long before the construction of the Felipe Ángeles International Airport, which lies northeast of Mexico City, the area was home to the former Lake Xaltocan and inhabited by a rich ecosystem of prehistoric animals. Eons later, in 2019, the somewhat controversial construction of the airport began, which led to the unearthing of at least 110 individual mammoths, as well as many other animal fossils.
	Did a single genetic mutation make horses rideable? Domestication of the horse was one of the crowning achievements of early humans. It led to advancements in transportation, warfare and agriculture, effectively galloping societies into the modern era.
	Engineers send quantum signals with standard Internet Protocol In a first-of-its-kind experiment, engineers at the University of Pennsylvania brought quantum networking out of the lab and onto commercial fiber-optic cables using the same Internet Protocol (IP) that powers today's web.
	Glow-in-the-dark succulents that recharge with sunlight could pave way to plant-based lighting systems From mushrooms that cast a soft green glow to plankton that glimmers sparkling blue, glowing plants are nothing new to nature. Now, scientists are bringing that light to houseplants.
	Optoelectronics research could bring holograms to your smartphone and closer to everyday use New research from the University of St Andrews paves the way for holographic technology, with the potential to transform smart devices, communication, gaming and entertainment.
	Ancient DNA solves Plague of Justinian mystery to rewrite pandemic history For the first time, researchers have uncovered direct genomic evidence of the bacterium behind the Plague of Justinian—the world's first recorded pandemic—in the Eastern Mediterranean, where the outbreak was first described nearly 1,500 years ago.
	Was Jesus's body wrapped in the Shroud of Turin? Newly discovered medieval document suggests not Newly uncovered medieval evidence is the latest to cast doubt on the authenticity of the Shroud of Turin, the linen cloth many believe was used to wrap the crucified body of Jesus.
	Braided magnetic flux ropes found at both human and light year scales Investigating solar corona structures has led Paul Bellan, Caltech professor of applied physics, and his former graduate student Yang Zhang (Ph.D. '24) to discover a new equilibrium state of the magnetic field and its associated plasma. The solar corona, the outermost part of the sun's atmosphere, is much less dense than the sun's surface but is a million times hotter. The corona is composed of strong magnetic fields confining plasma, a gaseous soup of charged particles (electrons and ions).
