Researchers improve tunability in optical differentiation
A new technique may make it easier for researchers to create real-time images of microscopic samples by considering the waves that propagate through sample surfaces as light interacts with them......»»
An AI tool for scanning sand grains opens windows into recent time and the deep past
Stanford researchers have developed an artificial intelligence-based tool—dubbed SandAI—that can reveal the history of quartz sand grains going back hundreds of millions of years. With SandAI, researchers can tell with high accuracy if wind, rive.....»»
Are white patches on whale shark skin cause for concern?
Marine scientists have been taking samples from whale shark skin to try and determine the effect of pollutants on whale health......»»
Ethics of biobanking for conservation: Researchers adjust ethical assessment tool for the use of genome research banks
In the face of the global biodiversity crisis, more and more biobanks are being set up to safeguard and potentially restore genetic diversity. Preserved tissue or cells allow scientists and conservationists to overcome spatial and even temporal fragm.....»»
Trilobite fossils from upstate New York reveal "extra" set of legs
A new study finds that a trilobite species with exceptionally well-preserved fossils from upstate New York has an additional set of legs underneath its head. The research, led by the American Museum of Natural History and Nanjing University in China,.....»»
Human "molecular map" contributes to the understanding of disease mechanisms
Scientists at Weill Cornell Medicine in Qatar (WCM-Q) have created an intricate molecular map of the human body and its complex physiological processes based on the analysis of thousands of molecules in blood, urine and saliva samples from 391 volunt.....»»
Genomic analysis confirms the uniqueness of Iberian red deer in Europe
A genome study of more than 700 European red deer has identified four distribution areas on the continent (Norway, Scotland, Spain and Central Europe), each with their own genetic characteristics that need to be preserved.....»»
Greenpeace sounds alarm on microplastics ingested by Hong Kong wildlife
Microplastic particles turned up in the vast majority of waste samples taken from Hong Kong wildlife in a Greenpeace study, the group said Monday, suggesting that animals still ingest plastics even if they are not feeding in urban areas......»»
The moon had surprisingly recent volcanic activity, samples from Chinese space mission confirm
Volcanoes were erupting on the moon as recently as 120 million years ago, evidence collected by a Chinese spacecraft suggests. Until the last few years, scientists had thought volcanic activity ended on the moon around 2 billion years ago......»»
With NASA’s plan faltering, China knows it can be first with Mars sample return
"China is likely to become the first country to return samples from Mars." Enlarge / A "selfie" photo of China's Zhurong rover and the Tianwen-1 landing platform on Mars in 2021. (credit: China National Space Administration).....»»
SF Bay area study reveals chemical levels in bottled, tap and household-treated tap water
A team of water technicians at water testing company SimpleLab has tested chemical levels in hundreds of water samples collected from bottles, household taps and treated tap water in the San Francisco Bay area. Their paper is published in the journal.....»»
Ancient viral genomes preserved in glaciers reveal climate history—and how viruses adapt to climate change
As humans alter the planet's climate and ecosystems, scientists are looking to Earth's history to help predict what may unfold from climate change. To this end, massive ice structures like glaciers serve as nature's freezers, archiving detailed recor.....»»
Novel probiotics identified in traditional Brazilian cheeses
Research conducted at the Center for Dairy Technology (Tecnolat) in Campinas, São Paulo state, Brazil, has identified lactic acid bacteria (LAB) that have probiotic properties and are beneficial to human health in samples of traditional Brazilian ch.....»»
Citizen scientists can help save Australia"s threatened species if given more direction
Across Australia and around the world, citizen scientists are protecting species by recording sightings, surveying landscapes and collecting samples. No job is too big or too small. As wildlife ecologists, we are indebted to this army of volunteers......»»
Locked in a glacier: Virus adaptations to extreme weather provide climate change insights
Ancient viruses preserved in glacial ice hold valuable information about changes in Earth's climate, a new study suggests......»»
Fossil hotspots in Africa obscure a more complete picture of human evolution, study says
Much of the early human fossil record originates from just a few places in Africa, where favorable geological conditions have preserved a trove of fossils used by scientists to reconstruct the story of human evolution......»»
Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
New leak suggests fourth iPhone 16 Pro lineup color is more "dark gold" than "brown"
A new photo from frequent leaker Maijin Bu on X.com shows color samples purported to be from the forthcoming iPhone 16 Pro lineup. The report suggests that earlier photos of a brownish "desert titanium" option may be misleading.The iPhone 16 Pro line.....»»
Rocks collected on Mars hold key to water and perhaps life on the planet: Researchers urge bringing them back to Earth
Over the course of nearly five months in 2022, NASA's Perseverance rover collected rock samples from Mars that could rewrite the history of water on the red planet and even contain evidence for past life on Mars......»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
