Inhaling cannabis may greatly increase your risk of getting asthma

If you’re looking to reduce your chances of developing lung disease, say experts at UC San Francisco, then it may be smart to avoid inhaling cannabis.

A new study in the Journal of General Internal Medicine found that inhaling marijuana every day is associated with a 44% increased chance of developing asthma. It also increased the odds of developing chronic obstructive pulmonary disease (COPD) by 27%.

The COPD risk may be understated, since the disease takes decades to develop, and the researchers did not have detailed information on how long people in the study had been using cannabis.

Galaxies Reveal Hidden Maps of Dark Matter in the Early Universe

Researchers uncover a key protein and a promising strategy to prevent bone damage from steroids.

The rheumatology and orthopedic researchers discovered that a protein called Basigin, which gets activated in stem cells when people take steroids, is a key reason why bones weaken and blood vessels in bone tissue become abnormal. By blocking Basigin, they were able to protect and even restore bone health in mice, suggesting a promising new treatment path.

Their findings were published in Nature Communications.

Graph neural networks learn emergent tissue properties from spatial molecular profiles

Tissue phenotypes arise from molecular states of individual cells and their spatial organisation, so spatial omics assays can help reveal how they emerge. Here, the authors apply graph neural networks to classify tissue phenotypes from spatial omics patterns, and use this approach to understand patterns in cancers and their microenvironments.

DNA Study of 117-Year-Old Woman Reveals Clues to a Long Life

There’s no escaping the unrelenting passage of time, but supercentenarians who live to see their 110th birthday have a peculiar ability to postpone the inevitable.

A thorough health evaluation of one of the world’s oldest people, Maria Branyas, suggests that one of the reasons she lived to 117 was that she possessed an exceptionally young genome.

Some of her rare genetic variants are linked to longevity, immune function, and a healthy heart and brain.

Cryosphere Chat — Strategies For Convincing Normies, Hibernation vs. Cryosleep, Organ Preservation

In this Cryosphere Chat we discuss the organ preservation to cryonics pipeline, our experiences trying to convince normies to sign up, using terms like hibernation or cryosleep instead of death, and more.

A New Eye on Earth’s Edge: UC Berkeley-Guided Space Telescope Has Liftoff

Engineers work in the Mission Operations Center at the Space Sciences Laboratory at UC Berkeley on Sept. 25, 2025. A UC Berkeley lab is controlling a NASA mission to study the farthest reaches of Earth’s atmosphere from afar.

This week, a rocket lifted off from Florida’s Kennedy Space Center carrying a new space telescope to its parking spot about 1 million miles from Earth, guided by mission operators at the Space Sciences Laboratory at UC Berkeley.

Once it reaches its permanent home, the Carruthers Geocorona Observatory will turn its eyes back to Earth to study the exosphere — the outermost layer of our atmosphere, where satellites orbit. Researchers hope that by better understanding how this region interacts with space weather from the Sun, they’ll be able to improve protections for satellites, which can be knocked offline by solar activity.

China introduces new ‘bone glue’ inspired by oysters for fast fracture repairing

A Chinese research team in East China’s Zhejiang Province unveiled an innovative product called “Bone 02” bone glue on Wednesday. Inspired by oysters, this glue can treat fractures with a single injection and bond shattered bone fragments in just three minutes, according to local media Zhejiang Online.

The team leader, Lin Xianfeng, an associate chief orthopedic surgeon at Sir Run Run Shaw Hospital affiliated with the renowned Zhejiang University, said the adhesive can achieve precise fixation within two to three minutes, even in a blood-rich environment. In one trial case, the procedure was completed in less than three minutes — whereas traditional treatment would have required a large incision to implant steel plates and screws, Zhejiang Online said.

Laboratory tests confirmed that ‘Bone-02’ performed strongly in both safety and effectiveness. It demonstrated a maximum bonding force of over 400 pounds, a shear strength of about 0.5 MPa, and a compressive strength of around 10 MPa. These properties suggest it has the potential to replace traditional metal implants, while also reducing the risks of foreign-body reactions and infection, said the report.

Physicists demonstrate 3,000 quantum-bit system capable of continuous operation

One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 quantum bits could simultaneously store more information than the number of particles in the known universe.

Now process this: Harvard scientists just unveiled a system that was 10 times bigger and the first quantum machine able to operate continuously without restarting.

In a paper published in the journal Nature, the team demonstrated a system of more than 3,000 (or qubits) that could run for more than two hours, surmounting a series of technical challenges and representing a significant step toward building the super computers, which could revolutionize science, medicine, finance, and other fields.
