Rotifers are excellent research organisms for studying the biology of aging, DNA repair mechanisms, and other fundamental questions. Now, using an innovative application of CRISPrCas9, scientists at the Marine Biological Laboratory, Woods Hole, have devised a method for making precise, heritable changes to the rotifer genome, enabling the larger community of scientists to deploy the rotifer as a genetically tractable lab organism.
Scientists with the Huazhong University of Science and Technology have replicated LK-99’s levitation abilities at room temperature, which they showcased in a video uploaded to Billibilli.
Topology has become a critical factor in the field of modern condensed matter physics and beyond. It explains the way solid materials may possess two distinct and seemingly conflicting characteristics. An example of this is topological insulators, materials whose bulk acts as an insulator, and can still conduct electricity at their surfaces and edges.
Over the past several decades, the idea of topology has revolutionized the understanding of electronic structure and the overall properties of materials. Additionally, it has opened doors to technological advancements by facilitating the integration of topological materials into electronic applications.
At the same time, topology is quite tricky to measure, often requiring combinations of multiple experimental techniques such as photoemission and transport measurements. A method known as high harmonic spectroscopy has recently emerged as a key technique to observe the topology of a material. In this approach a material is irradiated by intense laser light.
Tropical mosquitoes are increasingly widespread across the planet, and their leap to new continents could be incubating the next global human pandemic.

Local and federal authorities spent months investigating a warehouse in Fresno County, California, that they suspect was home to an illegal, unlicensed laboratory full of lab mice, medical waste and hazardous materials.
The Fresno County Public Health Department has been “evaluating and assessing the activities of an unlicensed laboratory” in Reedley, the health department’s assistant director, Joe Prado, said in a statement Thursday. All of the biological agents were destroyed by July 7 following a legal abatement process by the agency.
“The evaluation required coordination and collaboration with multiple federal and state agencies to determine and classify biological and chemical contents onsite, in addition to assessing jurisdictional authority under this unique situation,” Prado said.
When Samuel Peralta contacts artists about putting their work on the moon, they don’t always believe him.
“I say, ‘I’d like to put your art on the moon,’ and they think this is some sort of a scam,” the semiretired physicist and author tells the New York Times’ J. D. Biersdorfer.
But it’s true. Peralta is the mastermind behind the Lunar Codex, a series of time capsules containing the work of 30,000 artists from 157 countries that will journey to the lunar surface. Peralta wants the project to honor artists after the difficulties they faced during the pandemic, he tells the Toronto Star’s Kevin Jiang.

Juno’s orbit around Jupiter will bring it even closer to Io. By year’s end, in late December, the spacecraft will make its closest pass by Io (with another in early 2024).
The Cygnus NG-19 cargo freighter arrived at the International Space Station on Friday, Aug. 4, after a two-day space ride with 8,200 pounds (3,700 kilograms) of supply, experiments and new technology aboard.
The craft, built by U.S. aerospace giant Northrop Grumman and named after astronaut Laurel Clark who perished during the Columbia space shuttle disaster in 2003, was the last to launch on a version of the company’s Antares rocket using a first stage built in Ukraine.
In April, Alibaba launched its large language model (LLM) called Tongyi Qianwen. A LLM is an artificial intelligence model trained on huge amounts of data. It is also the basis for generative AI applications, such as ChatGPT — which generate human-like responses to user prompts.
Tongyi Qianwen allows AI content generation in English and Chinese and has different model sizes, including seven billion parameters and above. A model’s parameters refer to its power.
Alibaba will be open-sourcing the seven-billion-parameter model called Qwen-7B, along with a version designed for conversational apps, called Qwen-7B-Chat. This means that researchers, academics and companies globally can use the model to create their own generative AI apps without needing to train their own systems, saving time and expense. Companies with more than 100 million monthly active users will require a royalty-free license from Alibaba to do so.
Is the Ira Rubinoff Director of the Smithsonian Tropical Research Institute (STRI https://www.si.edu/about/bios/joshua-tewksbury), part of the Smithsonian Institution, the world’s largest museum, education, and research complex. He oversees more than 400 employees, with an annual budget of $35 million. Headquartered in Panama City, Panama, with field sites around the world, STRI furthers the understanding and public awareness of tropical biodiversity and its importance to human welfare. In addition to its resident scientists and support staff, STRI’s facilities are used annually by some 1,400 visiting scientists, pre-and postdoctoral fellows and interns from around the world.
Dr. Tewksbury is an ecologist with more than two decades of research in conservation and biodiversity, as well as nearly a decade of executive leadership experience at international research institutes.
Prior to his role at the STRI, Dr. Tewksbury was serving as Executive Director at Future Earth, a global research program dedicated to sustainability and global change, where he led a network of tens of thousands of scientists and managed a wide range of conservation research projects, staff, programs and partnerships.
In this role at Future Earth, Dr. Tewksbury oversaw dozens of interdisciplinary research projects, from assessing threats to biodiversity to understanding the relationship between human and environmental health. He has also founded initiatives like the Earth Leadership Program, which supported skills development for academic researchers working to address sustainability challenges. Previously, he was the founding director of the Luc Hoffman Institute, a global research center within World Wildlife Fund International focused on conservation science.
