When children lose their baby teeth, there is an adult set already growing beneath the gums, ready to emerge. But if we lose our permanent teeth, there aren't any more waiting in the wings. Right now, the options for replacing these lost teeth are either dentures or titanium implants, neither of which provide the same function and feedback as a real, living tooth.

Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions from the liquid. This creates two distinct charged regions: the surface itself and a counter-charged region in the liquid: the so-called electrical double layer. While pivotal to energy storage devices, the speed of its formation has remained elusive.

Solar flares accelerate energetic electrons that escape into interplanetary space, guided by the Parker spiral magnetic field, and are responsible for the generation of the interplanetary Type III solar radio bursts. With multiple spacecraft now in orbit around the sun, we are in a unique position of observing the propagation of radio emission through the heliosphere from multiple vantage points.

A team of fusion researchers at TAE Technologies, Inc., in the U.S., working with colleagues from the University of California, has developed a new type of fusion technology that the company claims produces 100 times the power of other designs while costing just half as much to run. Their study is published in the journal Nature Communications.

April 25 is International DNA Day, and it marks the completion of a decade-long project to sequence the DNA of Hong Kong's floral emblem, the Hong Kong Orchid Tree Bauhinia x blakeana Dunn.

Have you ever wondered if there is a way to heal bones without having to take bone from another part of the body? A new doctoral thesis from the University of Borås, Sweden, now presents exciting advancements in this area. It involves using bacteria to produce fibers that can help heal bones.

A celestial shadow known as the Circinus West molecular cloud creeps across this image captured from Chile with the 570-megapixel Department of Energy–fabricated Dark Energy Camera—one of the most powerful digital cameras in the world. Within this stellar nursery's opaque boundaries, infant stars ignite within cold, dense gas and dust, while outflows hurtle leftover material into space.

A research team has developed a highly stable and efficient water oxidation catalyst, marking a major advancement in the field of green hydrogen production via water splitting technology.

If an experiment is repeated under similar conditions, the results should be the same. In reality, the situation is often different—scientists speak of a "reproducibility crisis," which affects different disciplines.

Researchers from Sun Yat-sen University (SYSU) and the Institute of High Energy Physics (IHEP) have developed a novel top veto tracker system for the Taishan Antineutrino Observatory (TAO) experiment.

Skeptical Science is partnering with Gigafact to produce fact briefs — bite-sized fact checks of trending claims. You can submit claims you think need checking via the tipline. Do the 31,000 signatures of the OISM Petition Project invalidate the scientific consensus on climate change? Climatologists made up only 0.1% of signatories to a 1998 petition denying human-caused climate change — the consensus among qualified scientists stands. Anyone claiming they had a science degree could sign the petition without expertise in climate

As mentioned in the recently published prolog to EGU2025 article, I submitted an abstract to talk about some of our translation activities and the challenges we have been facing with those. This blog post is a "companion article" to that presentation in session EOS4.3 Geoethics and Global Anthropogenic Change: Geoscience for Policy, Action and Education in Addressing the Climate and Ecological Crises and will go into somewhat greater details than is possible in the 8 minutes available during the oral session which will be happening on May 2. Please note that what follows is by no means meant as a crtiicism of the many volunteer translator teams, of whom we are very appreciative for the work they did over the years, creating

This is a re-post from The Climate Brink The world has made real progress toward tacking climate change in recent years, with spending on clean energy technologies skyrocketing from hundreds of billions to trillions of dollars globally over the past decade, and global CO2 emissions plateauing. This has contributed to a reassessment of likely climate outcomes this century, with the world now likely heading toward less than 3C warming by 2100 under current policies – compared to the 4C warming that seemed more plausible 15 years ago.

A listing of 28 news and opinion articles we found interesting and shared on social media during the past week: Sun, April 13, 2025 thru Sat, April 19, 2025. This week's roundup is again published by category and sorted by number of articles included in each. The formatting is a bit different compared to previous weeks, though. We are still interested in feedback to hone the categorization, so if you spot any clear misses and/or have suggestions for additional categories, please let us know in the comments. Thanks! Stories we promoted this week, by category: Climate Policy and Politics (13 articles) EPA plans target climate change initiatives Environmental law experts say rollbacks will reverse adva

Skeptical Science is partnering with Gigafact to produce fact briefs — bite-sized fact checks of trending claims. You can submit claims you think need checking via the tipline. Is climate change a net benefit for society? Human-caused climate change has been a net detriment to society as measured by loss of life, economic harm and ecosystem damage. Between 2000 and 2019, climate change caused $2.86 trillion in damages from extreme weather like storms, floods, droughts, and wildfires. Nearly 61,000 net deaths were linked to climate cha

Open access notables Recent intensified riverine CO2 emission across the Northern Hemisphere permafrost region, Mu et al., Nature Communications: Global warming causes permafrost thawing, transferring large amounts of soil carbon into rivers, which inevitably accelerates riverine CO2 release. However, temporally and spatially explicit variations of riverine CO2 emissions remain unclear, limiting the assessment of land carbon-climate feedback. Using new and published 5685 riverine CO2 partial pressure data in the Arctic and Tibetan Plateau, we show that current riverine CO2 emission across the Northern Hemisphere permafrost zone is 200 ± 15 Tg C yr?1. The emission offsets

This video includes personal musings and conclusions of the creator climate scientist Dr. Adam Levy. It is presented to our readers as an informed perspective. Please see video description for references (if any). From "founder" of Tesla and the OG rocket man with SpaceX, and rebranding twitter as X, Musk has made a name for himself... partly as climate champion. But as his actions and words become increasingly friendly toward Donald Trump and global fascist ideas, can he still be held up as a climate expert? I take back a look at how Musk's climate speech has changed over the past decade - what's stayed the same, and what has fundamentally changed.
