JWST Maps the Weather on a Hot Gas Giant 700 Light-Years Away
Astronomers used the James Webb Space Telescope’s limb‑resolved spectroscopy to split the transit of hot gas giant WASP‑94A b into separate morning‑ and evening‑limb spectra. The morning limb is shrouded in high‑altitude aerosols, while the evening limb shows clear water‑vapor signatures, revealing a 450 K temperature contrast driven by equatorial super‑rotation. This temperature gap evaporates clouds by the evening side, altering the planet’s observed composition. When the spectra are averaged, oxygen enrichment appears 100‑times solar, but resolved data reduce it to 3‑5‑times, exposing a major bias in exoplanet atmospheric analysis.
Chickens without Eggs? De-Extinction Company Creates Artificial Egg.
Biotech startup Colossal unveiled a 3‑D‑printed artificial eggshell that lets chicken embryos develop outside a natural shell. The device preserves membrane tension, supplies oxygen through a permeable membrane, and supports normal chick hatching after transferring egg contents within a day....
A Revolutionary Cancer Treatment Could Transform Autoimmune Disease
Researchers are expanding CAR T cell therapy, originally a cancer breakthrough, to treat autoimmune diseases such as multiple sclerosis, lupus, and stiff‑person syndrome. Early trials, including a 2025 Nebraska study and a 2025 Kyverna trial of 26 stiff‑person patients, report functional...
Making Cement From a Different Type of Rock Could Clean up Emissions
A recent study proposes making Portland cement from basalt instead of limestone, eliminating the direct CO₂ released during calcination. The basalt‑based route uses acid leaching and precipitation to produce calcium hydroxide, then kilns the material with only water vapor as...
Rocket Report: Cowboy up for Data Centers in LEO; Russia's New ICBM Actually Works
The week’s Rocket Report highlighted a wave of activity across the global space sector, from SpaceX’s upcoming Starship Version 3 test flight aimed at in‑orbit refueling for Artemis III to India’s Skyroot Aerospace preparing its Vikram‑1 launch vehicle after a $60 million raise....
Once Again, SpaceX Has Set a New Record for the Tallest Rocket Ever Built
SpaceX has stacked its newest Starship Version 3, a 408‑foot vehicle that eclipses previous models, at a brand‑new launch pad in South Texas. The rocket features uprated Raptor 3 engines delivering roughly 18 million pounds of thrust—about 10% more than earlier versions—and a...
Do You Take After Your Dad’s RNA?
A 2025 mouse study showed that fathers who exercised before conception produce offspring with superior endurance, driven by elevated microRNAs in their sperm. Injecting these RNAs into unrelated embryos replicated the fitness boost, confirming a causal link at natural sperm...
SpaceX Is Starting to Move on From the World's Most Successful Rocket
SpaceX’s Falcon 9 launch cadence is beginning to taper as the company pivots toward its larger Starship system. After 165 Falcon 9 flights in 2025, the firm projects roughly 140‑145 launches in 2026, with a gradual decline thereafter. The shift is most...
Rocket Report: Falcon Heavy Is Back; Russia's Soyuz-5 Finally Debuts
SpaceX’s Falcon Heavy lifted off from Florida on April 29, marking its first flight since October 2024 and delivering a ViaSat‑3 broadband satellite. Russia debuted its new Soyuz‑5 rocket from Baikonur, a sub‑orbital test that replaces the aging Zenit family. In the same...
Professional School Grads From Diverse Classes Get Higher Salaries
A new study of roughly 3,000 business‑school and law‑school graduates finds that cohorts with higher racial diversity earn significantly higher starting salaries. The analysis, spanning 20 years and 350 institutions, shows the salary premium persists after controlling for prestige, location,...
New Robotic Control Software Avoids Jamming Their Joints
Researchers at EPFL have unveiled a framework called Kinematic Intelligence that lets robots share learned tasks across different hardware without retraining. By mathematically mapping each arm’s joint limits and singularities, the system reroutes motions around danger zones, ensuring safe execution....
This Is Who's Developing Golden Dome's Orbital Interceptors—If They're Ever Built
The U.S. Space Force announced a roster of 12 companies—including SpaceX, Lockheed Martin, Anduril, and Booz Allen—receiving up to $3.2 billion in OTA contracts to develop Space‑Based Interceptors (SBIs) for the Golden Dome missile‑defense program. The awards target early‑stage prototypes and aim...
Carbon Nanotube Wiring Gets Closer to Competing with Copper
Researchers in Spain have doped bulk double‑walled carbon‑nanotube fibers with tetrachloroaluminate, boosting their electrical conductivity up to ten times the undoped baseline and reaching about 70% of aluminum’s conductivity, roughly half of copper’s. The doped fibers retain their lightweight nature,...
We Still Don't Have a More Precise Value for "Big G"
Physicists have long struggled to pin down the gravitational constant, “Big G,” which still varies by about one part in 10,000 across experiments. A team at the National Institute of Standards and Technology (NIST) spent a decade replicating a 2007 French BIPM...
US Space Command: Russia Is Now Operationalizing Co-Orbital ASAT Weapons
U.S. Space Command announced that Russia’s Nivelir co‑orbital anti‑satellite system is now operational, targeting high‑value U.S. National Reconnaissance Office (NRO) satellites in low‑Earth orbit. The nesting‑doll architecture releases smaller craft capable of high‑velocity impacts, a capability first tested in 2020...
