Science brief
From Air-Grown Protein to Quantum Secrets
Israeli researchers engineer carbon-eating bacteria, reverse stem cell damage, and unlock a superconducting mystery.
Science
Weizmann's carbon-eating bacteria offer a theoretical path to decoupling food production from agricultural land — genetically modified microbes could soon synthesize proteins directly from industrial carbon emissions.
BackgroundProf. Ron Milo's laboratory previously made waves by programming bacteria to consume carbon dioxide instead of sugar. Traditional agricultural practices face intense land and water pressures, driving researchers to seek alternative carbon-eating organisms.
- The team programmed the bacteria to build specialized structures that allow them to absorb larger volumes of carbon dioxide and grow significantly faster, accelerating laboratory growth rates.
- Master's student Klil Halevi presented the biological breakthrough at the annual Israel Society of Ecology and Environmental Sciences conference, drawing widespread interest from environmental researchers.
- The technology aims to produce sustainable animal feed and human food supplements, potentially bypassing the need for agricultural land and reducing agricultural emissions.
Science
Chronic infection damage to blood-producing stem cells is reversible — proving that targeted antibiotics can fully restore the bone marrow niche will immediately make bone marrow transplants safer for cancer patients.
BackgroundChronic salmonella infections are known to severely deplete and damage hematopoietic stem cells, which reside in the bone marrow and generate the body's entire blood supply. The research was led by Prof. Roi Gazit and published in the journal Cell Reports.
- Using a novel mouse model that replicates chronic human infection, researchers proved that timely antibiotic interventions restored stem cell counts to healthy levels, reversing infection-induced damage.
- The study reveals a previously unknown level of resilience in the bone marrow's blood-producing niche, challenging the assumption that chronic bacterial stress causes permanent depletion.
- The discoveries are highly relevant to clinical oncology, where patients frequently suffer from persistent, transplant-sabotaging infections that complicate cancer therapies.

Hebrew University's discovery of a hidden dual-state in niobium diselenide solves a solid-state puzzle — controlling these twin quantum states will help engineers design more stable superconducting quantum computers.
BackgroundNiobium diselenide is a key two-dimensional material that has been studied globally for decades, but was previously believed to possess a single, simple superconducting energy gap. The research was guided by Professors Oded Millo and Hadar Steinberg alongside doctoral student Shahar Simon.
- The research team utilized high-resolution scanning tunneling microscopy to observe the material at its absolute thinnest limit, revealing the hidden dual-state structure for the first time.
- The discovery provides a robust physical foundation to design next-generation quantum computers, potentially reducing the error rates that currently plague advanced microelectronics.
- By explaining the material's hidden dual identity, the study resolves key mathematical discrepancies that have puzzled solid-state physicists for 20 years, streamlining future material design.
