Dr. Rumi Chunara: “Our system learns to recognize more subtle patterns that distinguish trees from grass, even in challenging urban environments.”

How can artificial intelligence (AI) help improve city planning to account for more green spaces? This is what a recent study published in the ACM Journal on Computing and Sustainable Societies hopes to address as a team of researchers proposed a novel concept using AI with the goal of both monitoring and improving urban green spaces, which are natural public spaces like parks and gardens, and provide a myriad of benefits, including physical and mental health, combating climate change, wildlife habitats, and increased social interaction.

For the study, the researchers developed a method they refer to as “green augmentation”, which uses an AI algorithm to analyze Google Earth satellite images with the goal of improving current AI methods by more accurately identifying green vegetation like grass and trees under various weather and seasonal conditions. For example, current AI methods identify green vegetation with an accuracy and reliability of 63.3 percent and 64 percent, respectively. Using this new method, the researchers successfully identified green vegetation with an accuracy and reliability of 89.4 percent and 90.6 percent, respectively.

“Previous methods relied on simple light wavelength measurements,” said Dr. Rumi Chunara, who is an associate professor of biostatistics at New York University and a co-author on the study. “Our system learns to recognize more subtle patterns that distinguish trees from grass, even in challenging urban environments. This type of data is necessary for urban planners to identify neighborhoods that lack vegetation so they can develop new green spaces that will deliver the most benefits possible. Without accurate mapping, cities cannot address disparities effectively.”

A new algorithm, Evo 2, trained on roughly 128,000 genomes—9.3 trillion DNA letter pairs—spanning all of life’s domains, is now the largest generative AI model for biology to date. Built by scientists at the Arc Institute, Stanford University, and Nvidia, Evo 2 can write whole chromosomes and small genomes from scratch.

It also learned how DNA mutations affect proteins, RNA, and overall health, shining light on “non-coding” regions, in particular. These mysterious sections of DNA don’t make proteins but often control gene activity and are linked to diseases.

The team has released Evo 2’s software code and model parameters to the scientific community for further exploration. Researchers can also access the tool through a user-friendly web interface. With Evo 2 as a foundation, scientists may develop more specific AI models. These could predict how mutations affect a protein’s function, how genes operate differently across cell types, or even help researchers design new genomes for synthetic biology.

WCTU CLEVELAND 13 — A new study suggests that faster-than-light travel, once thought to be purely science fiction, may be achievable sooner than expected through the concept of warp drive, challenging Einstein’s Theory of Relativity. This breakthrough builds on the Alcubierre drive model proposed in 1994, which theorizes that a spacecraft could travel faster than light by contracting space-time ahead of it while expanding space-time behind it.

The idea was first introduced by Mexican theoretical physicist Miguel Alcubierre, who suggested that a space-time bubble could allow for faster-than-light travel without violating the laws of physics. However, his model was initially dismissed due to its extreme energy requirements.

Joseph Agnew, a researcher from the University of Alabama, has been re-evaluating the mathematical foundations of Alcubierre’s theory. “If you fulfill all the energy requirements, they can’t prove that it doesn’t work,” Agnew stated in a university press release. His work has rekindled interest in the feasibility of warp drive by focusing on the possibility of warping space-time around a craft.

On Wednesday, NASA and SpaceX successfully launched the Intuitive Machines IM-2 mission from Kennedy Space Center in Florida. It aims to deliver multiple payloads, including NASA’s Lunar Trailblazer, to detect water on the Moon. The lander, named Athena, will take an eight-day journey to the Moon’s South Pole, where it will conduct studies on subsurface materials and volatile substances. Data collected from the mission could inform future Artemis program missions and commercial lunar activities.

All 10 NASA payloads remain healthy as Blue Ghost approaches it’s final destination and continues to support science operations along the way! The LuGRE payload for example — developed in partnership by.
NASA Goddard and ASI_spazio — acquired and tracked Global Navigation Satellite System signals for the first time in lunar orbit – a new record! #BGM1

After a successful Trans Lunar Injection burn on Saturday, Feb. 8, Firefly’s spacecraft carrying NASA science and tech to the Moon has departed Earth’s orbit and begun its four-day transit to the Moon’s orbit. Blue Ghost will then spend approximately 16 days in lunar orbit before beginning its descent operations. Since launching more than three weeks ago, Blue Ghost has performed dozens of health tests generating 13 gigabytes of data. All 10 NASA payloads onboard are currently healthy and ready for surface operations on the Moon.

NASA’s Radiation Tolerant Computer (RadPC), developed by Montana State University, successfully operated while passing through the Earth’s Van Allen radiation belts, providing insight on how to mitigate the effects of radiation on computers. This helps improve our understanding of the radiation environment that future astronauts may experience on Artemis missions.

During an on-orbit health check, NASA’s LMS, developed by the Southwest Research Institute, accurately detected a change in magnetic fields. This is a positive sign that LMS will be able to measure the Moon’s magnetic and electrical fields, shedding light on the Moon’s interior temperature and composition on the lunar surface.

This video shows basically that trash can be turned into treasure. From recycling food waste into dye to so much more. This video shows that basically pollution can be reduced by 95 percent. Also so that all resources from trash can be reincarnated into many new forms leaving no waste and creating a fully circular economy benefiting the environment.

21_21 DESIGN SIGHT in Tokyo’s Roppongi is currently showing a “pooploop” exhibition. Our presenters chat with exhibition directors Satoh Taku and Takemura Shinichi about cycles of waste and excrement around the planet, and explore the potential of environmental design.

In a unique study carried out in drinking water pipes in Sweden, researchers from Lund University and the local water company tested what would happen if chlorine was omitted from drinking water. The result? An increase in bacteria, of course, but after a while something surprising happened: a harmless predatory bacteria grew in numbers and ate most of the other bacteria. The study suggests that chlorine is not always needed if the filtration is efficient — and that predatory bacteria could perhaps be used to purify water in the future.

Just as human intestines contain a rich bacterial flora, many types of bacteria thrive in our drinking water and the pipes that transport them. On the inside of pipe walls is a thin, slippery coating, called a biofilm, which protects and supports bacteria. These bacteria have adapted to life in the presence of chlorine, which otherwise has the primary task to kill bacteria, particularity bacteria that can make humans sick.

An ordinary glass of drinking water contains a lot of harmless bacteria. Chlorine, however, which in the studied piping system was added in the form of monochloramine, is not wholly unproblematic.
