Science brief
Seed-Grown Dairy Proteins, Global Academic Standings, and Outer Solar System Geology
Hebrew University engineers safflower seeds to yield cow's milk protein, Israeli universities maintain top global ranks, and Pluto data reveals active subterranean nitrogen flows.
Science
Molecular farming in plant seeds creates a cheap, scalable alternative to livestock, turning standard crops into factories for complex animal proteins.
BackgroundPlant molecular farming introduces animal genes into crops to manufacture specific proteins at agricultural scale without dairy farming. Casein proteins are essential for cheese production and infant formula, but traditional livestock farming generates significant greenhouse gas emissions.
- Lead researcher Prof. Oded Shoseyov identified an intracellular transport mechanism that aggregates beta-casein into dense clusters within plant seeds, maximizing extraction yields during processing.
- The molecular farming technique enables large-scale production of animal-identical dairy proteins using standard agricultural harvesting equipment, significantly lowering capital requirements for alt-protein producers.
- Initial regulatory discussions are underway with global food safety authorities to approve plant-derived casein for commercial food manufacturing, opening a path toward market entry.
Science
Webb's infrared vision pierces cosmic dust to expose stellar nurseries, showing how massive stars shape nearby environments during early solar system formation.
BackgroundCometary globules are dense, compact clouds of interstellar gas and dust where new stars collapse under gravity. Optical telescopes cannot penetrate these opaque dust barriers, requiring infrared instruments to expose the early stages of star birth.
- Infrared images identified a massive O-type star 19 times larger than the Sun shaping neighboring gas clouds with intense ultraviolet radiation.
- Astronomers estimated the young stellar cluster is 1.3 million years old, offering a clear snapshot of early star cluster development.
- The observations allow astrophysicists to evaluate how intense stellar winds from massive stars impact planetary formation in neighboring solar systems.

Top Israeli institutions maintain strong scientific influence, but dropping ranks at tech-focused universities reveal growing global competition for research funding and top faculty talent.
BackgroundThe Shanghai Ranking evaluates over 2,500 higher education institutions worldwide using standardized metrics centered on high-impact research output. Israeli universities historically punch above their weight in natural sciences and technology, but global competition for faculty talent has intensified.
- The Weizmann Institute maintained its 71st global ranking due to high citation rates across physics, chemistry, and life sciences publications.
- The Technion fell out of the top 100 for the first time since 2020, reflecting tighter international competition and research funding pressures.
- Tel Aviv University ranked in the 151–200 tier, while Ben-Gurion University maintained its position within the top 500 global research universities.
Science
Internal geothermal heating keeps nitrogen liquid beneath Pluto's icy crust, proving dwarf planets at the edge of the solar system remain geologically active today.
BackgroundPluto's surface sits near minus 230 degrees Celsius, preserving vast glaciers made primarily of frozen nitrogen and water ice. Under atmospheric exposure surface liquid nitrogen quickly evaporates, making subsurface thermal heat the only mechanism capable of sustaining active liquid flows.
- High-resolution spatial mapping revealed dark, linear fluid channels emerging through structural crustal fractures along the northern boundary of Pluto's ice basin.
- Thermal modeling suggests internal decay of radioactive elements generates enough geothermal heat to keep nitrogen liquid inside subterranean reservoirs.
- The findings demonstrate that distant dwarf planets far from solar heat can maintain dynamic geology billions of years after their formation.
