Galactic gravity can dramatically impact wide binary stars, pushing them towards unexpected mergers or collisions.
The detection of gravitational waves.
Gravitational waves are distortions or ripples in the fabric of space and time. They were first detected in 2015 by the Advanced LIGO detectors and are produced by catastrophic events such as colliding black holes, supernovae, or merging neutron stars.

Researchers are starting to find patterns in how we sleep that could point to early signs of dementia or Parkinson’s disease.
There are some obvious signs that your loved one could be showing early signs of dementia, which affects almost seven million people in the US.
The common signs include being unable to learn new tasks, struggling to stay focussed, finding it hard to contribute in conversations, mistaking things for other objects and/or getting unusually emotional or afraid.
The Moon still holds mysteries that leave scientists in awe. A massive, heat-radiating object beneath its surface has sparked new questions about its origins.
This discovery offers a glimpse into the Moon’s hidden history, challenging what we thought we knew about our celestial neighbor.
Bryan Johnson said taking rapamycin may have done more harm than good to his health.
The Moon still holds mysteries that leave scientists in awe. A massive, heat-radiating object beneath its surface has sparked new questions about its origins.
This discovery offers a glimpse into the Moon’s hidden history, challenging what we thought we knew about our celestial neighbor.
The Moon, long considered a cold and barren landscape, has just revealed a fascinating new secret. Hidden beneath its far side lies a massive heat-emitting feature that has scientists buzzing with questions. This isn’t just any ordinary discovery—it involves a rare geological phenomenon typically associated with Earth.
“We initially expected the carbon-to-oxygen ratio in the planet might be similar to the disk,” said Dr. Chih-Chun “Dino” Hsu. “But, instead, we found the carbon, relative to oxygen, in the planet was much lower than the ratio in the disk.”
What is the official process of planetary formation and evolution and is this process uniform for all planetary bodies throughout the universe? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of researchers investigated a young exoplanet still forming within its protoplanetary disk that could offer clues into the secrets behind planetary formation and evolution. Additionally, it holds the potential to provide greater complexity with longstanding planetary formation models, which have traditionally presented simple scenarios for planetary formation and evolution.
For the study, the researchers used the W. M. Keck Observatory to observe PDS 70b, which is a gas giant planet approximately three Jupiter masses and located 369 light-years from Earth. What makes PDS 70b interesting for astronomers is its age, as it’s estimated to be approximately 5 million years old, meaning it is still gathering material from the system’s disk, also known as accretion.
Using Keck, the researchers analyzed the light spectra of PDS 70b’s atmosphere to ascertain its carbon-to-oxygen ration and compared this data to the carbon-oxygen ratio of the protoplanetary disk that PDS 70b resides. In the end, the researchers found that PDS 70b carbon-to-oxygen ratio was lower than the surrounding disk, which challenges previous notions of planetary formation models, and the methods used to build those models.
We work with a growing database of values-aligned specialists from across the world. These include scientific researchers, educators, thought-leaders, artists, companies, and nonprofits. Together, we co-create, accelerate, and amplify the impact of select projects. These projects are interdisciplinary in nature—often incorporating art, education, and research components to reach more diverse audiences, scale broader impacts, and deliver rapid change. These projects are frequently participatory, with the goal of democratizing the process of exploration and increasing the accessibility of findings, materials, and teachings. These projects are unique and may result in peer-reviewed research findings, open-source books, art exhibits, lesson plans, or innovative commercial products.
So, if all goes to plan, the Eco Rocket could become Japan’s first operational spaceplane. On its website, Space Walker explains that “we envision sustainable commercial space transportation for all, as familiar and accessible as commercial air travel today.”
The company says it has patented the technology behind a world-first lightweight-composite cryogenic propellant tank. It also emphasizes the value of reusability, which has been shown in practice by SpaceX’s incredibly successful Falcon 9 program. Space Walker will go the extra mile for sustainability, though, as the Eco Rocket will use a carbon-neutral liquefied biomethane propellant.
A team of math and AI researchers at Microsoft Asia has designed and developed a small language model (SLM) that can be used to solve math problems. The group has posted a paper on the arXiv preprint server outlining the technology and math behind the new tool and how well it has performed on standard benchmarks.
Over the past several years, multiple tech giants have been working hard to steadily improve their LLMs, resulting in AI products that have in a very short time become mainstream. Unfortunately, such tools require massive amounts of computer power, which means they consume a lot of electricity, making them expensive to maintain.
Because of that, some in the field have been turning to SLMs, which as their name implies, are smaller and thus far less resource intensive. Some are small enough to run on a local device. One of the main ways AI researchers make the best use of SLMs is by narrowing their focus—instead of trying to answer any question about anything, they are designed to answer questions about something much more specific—like math. In this new effort, Microsoft has focused its efforts on not just solving math problems, but also in teaching an SLM how to reason its way through a problem.
