Microbiome research reveals how bacterial lipids influence liver and muscle health in mice

An interdisciplinary team of researchers from UConn and the University of Pittsburgh is filling knowledge gaps about the surprising roles that our microbiomes play in our health. The team's recent studies, published in Gastro Hep Advances and The Journal of Physiology, focus on Bacteroidota species that grow in our guts and mouths, where they produce glycine lipids that interact with our metabolism.

Silent lakes ahead? Long-term study finds common loon productivity is dropping across North America

The eerie call of the common loon has long been the sound of North America's northern lakes, but new research shows it may not be that way in the future. A new study led by Birds Canada analyzed breeding attempts across nine Canadian provinces and seven U.S. states. The researchers found a widespread, long-term plunge in loon chick production across their range.

Global accounting reveals economic toll of ecosystem losses from rising seas

A global accounting puts the value of ecosystem services that could be lost to sea level rise at well over 100 billion in 2020 international dollars (Int$2020) per year by 2100, according to a study—and the nations that are likely to lose the most are not the highest emitters.

Researchers target PFAS with lower-temperature destruction method

Removing harmful chemicals from contaminated water is only one step toward their elimination. Once collected in filtration materials, these chemicals must still be destroyed and detoxified to prevent contamination from moving into another waste stream.

Reading single vesicles reveals clues to the origin of chronic inflammation

A new technique to diagnose chronic inflammation developed at Nagoya University can read information from the surface and within individual extracellular vesicles in blood and urine. This technique could be used to develop noninvasive tests that can not only detect chronic inflammation but also provide information about the tissues where it occurs.

Wherever there are people, there is also wildlife—though not necessarily at the same time

Human-induced global change has reached an unprecedented scale and intensity. Through intensive land use and the associated loss of species, humans are permanently altering the habitats and communities of wild animals. "How do predators manage to find their way in landscapes heavily shaped by humans and establish their niche? It is precisely this question that interested us," says Kathi Kasper, a doctoral student at the MRI PAS, the EBD-CSIC and the Leibniz-IZW and an author of the study.

A single measurement makes quantum bits more reliable

Researchers at the University of Regensburg and their international partners have found a way to significantly reduce errors in quantum bits. In an experiment, they demonstrated that a single additional measurement before a series of quantum operations can cut the error rate by more than half. The results have been published in Applied Physics Reviews.

Could One Brain Region Be Tied to Feeling Sick All Over?

When you break your foot, the pain is mostly confined to your foot. When you get the flu or another systemic infection, your entire being aches: Lethargy creeps into your limbs, your appetite vanishes, your temperature jags between scorching and chilled to the bone, and you just want to pull the covers over your head. This kind of overpowering mind-body malaise is known as “sickness syndrome,” and it’s considered a distinct physiological and emotional state. Scientists believe sickness syndrome helps the body prepare to fight infections, but they don’t fully understand what is happening in the

[分享发现] Opus5.5 做视频太贵，国产开源平替来了！

大家都还在为 Claude Opus 5.5 写代码做一条 15 秒视频花掉近百美元而感到心疼的时候，开源社区已经把写代码生成视频的底座给掀了 商汤开源的 SenseNova 6.8 Code2Video ，是一个专门通过编写和修改代码来生成视频的模型，27B 参数 本次公开了全量参数模型权重和配套的创作 Skill ，还支持对生成结果进行多轮自然语言精细修改，甚至能把一段没有任何源码的参考视频直接逆向重构为可编辑的代码工程，还挺 impressive 的 项目地址： https://github.com/OpenSenseNova/SenseNova-6.8-Code2Video 一、SenseNova 6.8 Code2Video 是怎么做出视频的？ 和 Sora 、Runway 等传统视频生成模型不同，SenseNova 6.8 Code2Video 不会去猜每一帧的像素，而是用代码将创意转化为视频，核心工作机制可以拆解为： 1. 底座：27B 专精模型 + 512K 超长上下文的代码生成 传统像素扩散模型在做科普视频、动态图形（ Motion Graphics ）或排版动画（ Typography ）时，经常出现文字拼写乱码、数学公式变形、物理碰撞穿模等问题，如果要精准渲染，这就不是模型能力或者参数的问题了，而是底层实现原理不一样 代码即画面：SenseNova 6.8 C
