Professor Edmund Lam, Dr. Ni Chen and their research team from the Department of Electrical and Electronic Engineering under the Faculty of Engineering at the University of Hong Kong (HKU) have developed a novel uncertainty-aware Fourier ptychography (UA-FP) technology that significantly enhances imaging system stability in complex real-world environments. The research has been published in Light: Science & Applications. /news/2025-10-uncertainty-aware-fourier-ptychography-imaging.html Optics & Photonics Mon, 13 Oct 2025 14:32:03 EDT news679584721 For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into the dry planet we see today. A new study published online on September 2, 2025, in the Geology journal, sheds light on this mystery by looking deep inside Martian craters, which act like "ice archives" that store a frozen record of the planet's past. These craters reveal that Mars went through repeated ice ages over hundreds of millions of years; however, with each cycle, the amount of remaining ice decreased steadily. /news/2025-10-frozen-clues-mars-crater-deposits.html Planetary Sciences Thu, 09 Oct 2025 09:49:04 EDT news679222141 Last year, we celebrated 50 years since the first papers on fluorescence correlation spectroscopy (FCS) were published. It wasn't a wild celebration with masses on the streets, nor was it widely celebrated in universities, but rather a quiet admiration by people in the field for one of the cornerstone methods that has advanced our understanding of many processes at the molecular scale. /news/2025-10-analysis-year-problem-molecular-fluorescence.html Biochemistry Analytical Chemistry Wed, 08 Oct 2025 12:29:13 EDT news679145341 The Gulf of Mexico, a regional ocean, is hugged by the southeastern United States and a large stretch of the Mexican coast, making it very important for both countries. The area helps bring goods to local and global markets, produces power for the country with off-shore oil rigs, and hosts a myriad of vacation-worthy beaches—so modeling and predicting its dynamics is a critical task. /news/2025-10-regional-ocean-dynamics-emulated-ai.html Earth Sciences Environment Wed, 08 Oct 2025 12:19:05 EDT news679144741 Antarctic krill, tiny shrimp-like creatures, are an important species in the Southern Ocean ecosystem and global carbon cycle, in part because of their poop. Their dense and rich fecal pellets sink rapidly, transporting carbon from surface waters to the deep ocean. In a new study published in the journal Biology Letters, scientists have discovered another way these crustaceans keep carbon locked away from the atmosphere—by ejecting carbon-rich masses of rejected food, called food boluses, that also plummet to the ocean depths. /news/2025-10-balls-krill-food-good-news.html Plants & Animals Ecology Wed, 08 Oct 2025 10:30:01 EDT news679138054 A new study co-led by the University of Oxford and Google Cloud has shown how general-purpose AI can accurately classify real changes in the night sky—such as an exploding star, a black hole tearing apart a passing star, a fast-moving asteroid, or a brief stellar flare from a compact star system—and explain its reasoning, without the need for complex training. /news/2025-10-ai-advance-astronomers-cosmic-events.html Astronomy Wed, 08 Oct 2025 05:00:05 EDT news678984481 In research that could improve weather forecasting and winter driving safety, a University of Michigan-led study distinguished nine distinct precipitation types—varieties of rain, snow and mixed-phase (e.g., sleet)—using unsupervised machine learning and nearly a decade's worth of high-speed camera data.

Reporting in iScience on October 3, the team shows that bacteria, acids, and enzymes in ants can kickstart the fermentation process that turns milk into yogurt.

However, the latter is not always the case, as a recent study in Royal Society Open Science by the University Hospital of WĂŒrzburg (UKW) shows. Prof. Dr. Grit Hein and her team at the Center for Translational Social Neuroscience at the Center for Mental Health (ZEP) investigated whether people from a particular group would approach a foreign group if they received money for doing so. /news/2025-10-money-buy-cooperation-deep-seated.html Social Sciences Economics & Business Thu, 02 Oct 2025 13:52:04 EDT news678631921 An enormous but poorly understood region of the global ocean—referred to as the abyssal benthic boundary layer—lies a few meters above the seafloor and has only been sampled a handful of times. A study by oceanographers at the University of HawaiÊ»i at Mānoa provided the first in-depth look at this habitat, revealing a dynamic community that may be more sensitive to seasonal changes than previously understood. /news/2025-10-rare-glimpse-understudied-ecosystem-prompts.html Ecology Thu, 02 Oct 2025 06:54:09 EDT news678606842 You probably learned in high school chemistry class that core electrons don't participate in chemical bonding. /news/2025-09-core-electron-bonding-require-extreme.html Analytical Chemistry Materials Science Tue, 30 Sep 2025 14:52:36 EDT news678462753 Convergent evolution—where distinct species independently evolve similar traits or functions, such as the wings of birds and bats—has long fascinated biologists. Now, a research team led by Prof. Zou Zhengting from the Institute of Zoology of the Chinese Academy of Sciences (CAS), has introduced a deep learning–based method to unravel the complex molecular mechanisms driving this phenomenon. /news/2025-09-deep-tool-unravel-molecular-mechanisms.html Evolution Molecular & Computational biology Tue, 30 Sep 2025 13:30:01 EDT news678455539 In July 2024, a 7.4-magnitude earthquake struck Calama, Chile, damaging buildings and causing power outages. The country has endured violent earthquakes, including the most powerful recorded in history: a 9.5-magnitude "megathrust" event that struck central Chile in 1960, causing a tsunami and killing between 1,000 to 6,000 people. However, the Calama quake was different from the megathrust quakes that are usually associated with the most destructive events in Chile and around the world. /news/2025-09-thermal-runaway-mechanism-ramp-magnitude.html Earth Sciences Tue, 30 Sep 2025 12:12:04 EDT news678453121 A recent study offers proof of feasibility for using cosmic radiation detectors to discover underground spaces. The detectors identify muons—particles created when cosmic radiation collides with Earth's atmosphere, which penetrate the ground before losing their energy and coming to a stop. Thus, by detecting muons, archaeologists can map hidden voids such as tunnels and channels. /news/2025-09-underground-spaces-muon-technology-3d.html Archaeology Mon, 29 Sep 2025 16:10:06 EDT news678380785 Johns Hopkins applied mathematicians and astronomers have developed a new method to render images from ground-based telescopes as clear as those taken from space, a process that stands to expand the benefits of Earth-based instruments. /news/2025-09-sharper-algorithm-stars-greater-focus.html Astronomy Mon, 29 Sep 2025 15:12:54 EDT news678377564 Scientists have sought to capture the first days of how a person comes to be, by recreating those early moments in a lab via models made up of induced pluripotent stem cells, or IPSCs. /news/2025-09-ai-reveals-hidden-features-embryo.html Cell & Microbiology Biotechnology Fri, 26 Sep 2025 11:57:04 EDT news678106622 Tens of thousands of earthquakes shook the Greek island of Santorini and the surrounding area at the beginning of the year.
