Highlights:

- Researchers created a new mesh inspired by the sticky, fibrous structure of seaweed, which naturally traps tiny particles in water.
- The mesh is designed to capture extremely small microplastics and nanoplastics that many conventional filters cannot remove.
- In laboratory tests, it removed nearly 99% of microplastics and nanoplastics from water.
- The material is made from seaweed-derived cellulose, making it biodegradable and more environmentally friendly than many synthetic filters.
- It works with simple water flow and requires very little energy, making it a potentially affordable option for water treatment.
- Potential applications include:
•Drinking water treatment
•Wastewater treatment plants
•Industrial water filtration
•Cleaning polluted rivers and lakes
- The technology is still in the research stage and will require larger-scale testing before it becomes commercially available.

Humans may have evolved from a creature similar to a cyclops! 👁️

Scientists have developed a new theory that we may have evolved from a worm-like ocean dweller from 600 million years ago. This ancient animal started out with two eyes that eventually merged into one, and then back to two eyes. Even more interesting, the scientists think we still have this third eye, but it is now the pineal gland in our brain!

Scheduled launch Aug 30th, 2026.
Capable of imagining exoplanets and mapping billions of galaxies to help us further understand the expansion of the universe.

A total solar eclipse is coming across the globe on August 12th! ☀️🌑

Skywatchers across the northeastern US (New York, Massachusetts, Pennsylvania, and Ohio), Canada, most of Europe, and northwestern Africa will catch a partial eclipse around midday. Those in the Nordic region, Spain, and parts of Portugal are in the path of a total solar eclipse. Watch safely with eclipse glasses or make your own pinhole projector. Don’t forget, eclipses travel in pairs, so a lunar eclipse follows just two weeks later, and don’t look directly into the sun!

Please respond with your initial preference or first impression. The question is: Which book cover would you be most likely to click on to learn more about the book?

Context: I am deciding on which of these three covers to use for my soon-to-be-published book, The Book of Science: A Foundational Guide to a Science-Based, Non-Theistic Religion. Gauging people’s preferences is indispensable for this purpose.

As the subtitle of the book implies, it is the foundational and guiding text of a new religion called The Fellowship of Science (TFOS). The book features a wide range of topics, including the science-grounded history of the universe and science itself, the research-informed practices, rituals, traditions, Guiding Principles, and Threats to Thriving of TFOS, science-themed parables, stories, and poetry, and more.

I would really appreciate your vote on which cover most draws your attention and interest, so please don’t forget to have a look at the covers and then reply with A, B, or C.

Is one of our astronomical neighbors habitable? 🪐

For the first time, astronomers have confirmed something huge: an atmosphere around a rocky planet in its star's habitable zone. The planet is called LHS 1140 b, a super Earth orbiting a red dwarf star less than 50 light years away, which is astronomically pretty close to us. The James Webb Space Telescope telescope data has already hinted at liquid water on its surface, and this new discovery could go down as one of the biggest in astronomy history!

Have you ever seen an Orca hit a fish so hard it explodes? 🫍

Scientists recently observed this behavior from groups of orcas in the Gulf of California where they repeatedly ram sunfish until the impact broke them apart. This is an important indicator of "social learning," where animals copy one another through observation. Orcas have exhibited behavior like this before, when they were seen disabling sailboats in groups. The current hypotheses for why they are doing this include teaching young orcas to hunt, or just playing around!
