Encapsulated Perovskite Solar Cells Show Resilience
The first outdoor test of perovskite-and-silicon solar cells lasting more than a year shows that the cells retained over 80 percent of their initial 21.6 percent solar-conversion efficiency. The encouraging results come from tests conducted in the sunny, hot, and humid climate of the Red Sea Coast of Saudi Arabia, in what is “the longest…

The soft robotic models are patient-specific and could help clinicians zero in on the best implant for an individual. — ScienceDaily
No two hearts beat alike. The size and shape of the the heart can vary from one person to the next. These differences can be particularly pronounced for people living with heart disease, as their hearts and major vessels work harder to overcome any compromised function. MIT engineers are hoping to help doctors tailor treatments…

Based on our current understanding of planet formation, TOI-5205b should not exist; it is a ‘forbidden’ planet.’ — ScienceDaily
A team of astronomers led by Carnegie’s Shubham Kanodia has discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings which are published in The Astronomical Journal, challenge long-held ideas about planet formation. Smaller and cooler than our Sun, M dwarfs are the…

Bandage also monitors the healing process, alerting clinicians to issues in real time — ScienceDaily
Northwestern University researchers have developed a first-of-its-kind small, flexible, stretchable bandage that accelerates healing by delivering electrotherapy directly to the wound site. In an animal study, the new bandage healed diabetic ulcers 30% faster than in mice without the bandage. The bandage also actively monitors the healing process and then harmlessly dissolves — electrodes and…

Meteorite crater discovered in French winery — ScienceDaily
With the aim of creating an appealing brand, the name of the ‘Domaine du Météore’ winery near the town of Béziers in Southern France points to a local peculiarity: one of its vineyards lies in a round, 200-metre-wide depression that resembles an impact crater. By means of rock and soil analyses, scientists led by cosmochemist…

James Webb spots super old, massive galaxies that shouldn’t exist — ScienceDaily
In a new study, an international team of astrophysicists has discovered several mysterious objects hiding in images from the James Webb Space Telescope: six potential galaxies that emerged so early in the universe’s history and are so massive they should not be possible under current cosmological theory. Each of the candidate galaxies may have existed…

This Particle Accelerator Makes a Substance That Has Not Existed in 13 Billion Years
By using one of the most complicated and powerful machines on the planet, scientists have found a way to glimpse back to the very beginning of time itself. This time machine is a particle accelerator, and it gives us a peek at the soup of our newborn universe. Just moments after the Big Bang, our…
