Researchers in South Korea injected grains of rice with cow muscle and fat cells to create something being called beef rice. This pink-colored substance could offer a cheaper and more sustainable protein source than standalone meat.
Tesla is now starting to account for “battery age” in its estimated range calculation for its electric vehicles.
I have long been advocating for prioritizing accurate range prediction over a longer range in curbing range anxiety.
Don’t get me wrong, a longer range can be useful, but if you know what where you are going, the main thing is that you know you can get there and your range doesn’t start dropping faster than anticipated.
Researchers at the Nanyang Technical University (NTU) in Singapore are leading the way in the development of soft electronics and have now set up a high-tech laboratory where they can rapidly prototype new devices with ultrathin and stretchable electronics.
Conventional electronics products are hard and rigid since they rely on silicon as their primary substrate. These products work well at industrial scales or even for personal use products.

The natural ends of chromosomes appear alarmingly like broken DNA, much as a snapped spaghetti strand is difficult to distinguish from its intact counterparts. Yet every cell in our bodies must have a way of differentiating between the two because the best way to protect the healthy end of a chromosome also happens to be the worst way to repair damaged DNA.
Consider the enzyme telomerase, which is responsible for maintaining protective telomeres at the natural ends of chromosomes. Were telomerase to seal off a broken strand of DNA with a telomere, it would prevent further repair of that break and delete essential genes.
Now, a new study in Science describes how cells avoid such mishaps. These findings show that telomerase can indeed run amok, adding telomeres to damaged DNA, and would do so were it not for the ATR kinase, a key enzyme that responds to DNA damage.
Remote surgery in orbit.
Earth-bound surgeons remotely controlled a small robot aboard the International Space Station over the weekend, conducting the first-ever such surgery in orbit—albeit on rubber bands.
The experiment, deemed a “huge success” by the participants, represents a new step in the development of space surgery, which could become necessary to treat medical emergencies during multi-year manned voyages, such as to Mars.

More than 4,500 heart transplants were performed in the U.S. in 2023. While the lifesaving operation improves the quality of life and longevity for most recipients, organ rejection remains a risk, with acute rejection occurring in up to 32% of recipients within the first year.
A team of researchers from Emory University, Case Western Reserve University and the University of Pennsylvania developed artificial intelligence tools to examine cardiac biopsy images to improve the prediction of rejection, helping to ensure patients receive the best possible post-transplant treatment.
Currently, clinicians rely on histologic grading of cardiac biopsies to diagnose acute rejection. However, there are limitations to the method, which assigns International Society of Heart and Lung Transplantation (ISHLT) histologic grades corresponding to no, mild, moderate and severe rejection.

In creating five new isotopes, an international research team working at the Facility for Rare Isotope Beams (FRIB) at Michigan State University has brought the stars closer to Earth.
The isotopes —known as thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190—are reported in the journal Physical Review Letters.
These represent the first batch of new isotopes made at FRIB, a user facility for the U.S. Department of Energy Office of Science, or DOE-SC, supporting the mission of the DOE-SC Office of Nuclear Physics. The new isotopes show that FRIB is nearing the creation of nuclear specimens that currently only exist when ultradense celestial bodies known as neutron stars crash into each other.
A new study, resorting to computational models, predicts that a subduction zone currently below the Gibraltar Strait will propagate further inside the Atlantic and contribute to forming an Atlantic subduction system—an Atlantic ring of fire. This will happen ‘soon’ in geological terms—in approximately 20 million years.
Oceans seem eternal to our lifespan, but they are not here for long: they are born, grow, and one day close. This process, which takes a few hundred million years, is called Wilson Cycle. The Atlantic, for example, was born when Pangea broke up around 180 million years ago and will one day close. And the Mediterranean is what remains from a big ocean—the Tethys– that once existed between Africa and Eurasia.
For an ocean like the Atlantic to stop growing and start closing, new subduction zones—places where one tectonic plate sinks below another—have to form. But subduction zones are hard to form, as they require plates to break and bend, and plates are very strong. A way out of this “paradox” is to consider that subduction zones can migrate from a dying ocean in which they already exist—the Mediterranean—into pristine oceans—such as the Atlantic. This process was dubbed subduction invasion.
