Beyond the cloud
Every day, more and more information is filed in less and less space. Even the cloud will eventually run out of space, can’t thwart all hackers, and gobbles up energy. Now, a new way to store information could stably house data for millions of years.
-
No laughing matter
A recent study shows that nitrous-oxide emissions from thawing Alaskan permafrost are about 12 times higher than previously assumed. About a quarter of the Northern Hemisphere is covered in permafrost, which is thawing at an increasing rate. And, even though researchers are monitoring carbon dioxide and methane, no one seems to be monitoring N2O, the most potent greenhouse gas.

Forward thinking
Research led by scientists at Harvard and the Broad Institute has optimized the process of making human brain “organoids” — miniature 3D organ models — so they consistently follow growth patterns observed in the developing human brain.
-
Editing genes at the source
Study shows how genes could be edited in stem cells within intact organs, without having to remove them from their normal environment. The new approach could treat a variety of diseases.
-
A new vision for neuroscience
For decades scientists have been searching for a way to watch a live broadcast of neurons firing in real time. Now, a Harvard researcher has done it with mice.

Researcher connects the dots in fin-to-limb evolution
With an innovative technique called anatomical network analysis, clear patterns emerge that help solve the puzzle of how fins became limbs 420 million years ago.
-
Learning why cancer drugs work (or don’t)
Assistant Professor Brian Liau of the Chemistry and Chemical Biology Department has answered the question of why some new drugs for acute myeloid leukemia don’t work by combining CRISPR gene editing with small-molecule inhibitor treatments in a technique he calls CRISPR-suppressor scanning.
-
The evolution of flightless birds
Based on an analysis of the genomes of more than a dozen flightless birds, including an extinct moa, a team led by Harvard researchers found that while different species show wide variety in the protein-coding portions of their genomes, they appear to turn to the same regulatory pathways when evolving flight loss.

Easy on the eyes
New computer program uses artificial intelligence to determine what visual neurons like to see. The approach could shed light on learning disabilities, autism spectrum disorders, and other neurologic conditions.
-
Researchers ID molecules that rein in CRISPR systems
Scientists have identified the first chemical compounds able to inhibit and regulate CRISPR systems, which could ultimately make CRISPR gene-editing technologies more precise, efficient, and safe.

AI model predicts TB resistance
A Harvard undergrad, working with Harvard Medical School scientists, has designed an artificial intelligence model that predicts tuberculosis resistance to 10 most commonly used drugs. The new model outperforms previous machine-learning tools, and incorporating it into clinical tests could dramatically enhance early detection and prompt treatment of drug-resistant TB.

Day of the golden jackal
The surprising success story of the golden jackal in Europe holds lessons about nature’s resilience and about how nature might respond to the evolutionary pressure exerted by humans as we change the natural landscape. The Gazette spoke with doctoral student Nathan Ranc for insight.

Rocketwoman
Fifty years ago this summer, Neil Armstrong took his “giant leap for mankind” on the moon. In his wake hundreds of others have flown into space, including Ellen Ochoa, a four-time shuttle astronaut who stepped down as director of the Johnson Space Center in 2018 and is currently a visiting fellow at the Harvard Kennedy School’s Center for Public Leadership.
