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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

A joint program of the computer science and philosophy departments, Embedded EthiCS has won a $150,000 grant as part of the Responsible Computer Science Challenge sponsored by Omidyar Network, Mozilla, Schmidt Futures, and Craig Newmark Philanthropies.

In a breakthrough on the road toward ultra-high-speed Wi-Fi, Harvard researchers have demonstrated for the first time a laser that can emit microwaves wirelessly, modulate them, and receive external radio frequency signals.

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.

The Weld Hill Solar Project, currently underway, is the Arnold Arboretum’s third and largest solar project and Harvard’s most ambitious sustainability initiative to date, with nearly 1,300 solar panels powering a 45,000-square-foot science laboratory and teaching facility in Roslindale.

Harvard doctoral students offered a glimpse of the future of evolutionary inquiry, outlining projects that touch on the human pelvis, butterfly hybrids, field and forest mice, and the mystery of an ancient pile of bones.

Scientists from Harvard and Princeton have teamed up to create an artificial intelligence algorithm that can predict destructive disruptions in nuclear fusion experiments

Architect and GSD Professor Scott Cohen discusses his studio course that considered how architects could help his beloved Provincetown, Mass., address the prospect of rising seas due to climate change while still retaining its quirky magic.

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.

Researchers have analyzed technical and economic viability for China to move toward carbon-negative electric power generation and found that China can do so in an economically competitive way.

Harvard researchers are proposing using a “primordial standard clock” as a probe of the primordial universe. The team laid out a method that may be used to falsify the inflationary theory experimentally.

Though they have unusual properties that could be useful in everything from superconductors to quantum computers, topological materials are frustratingly difficult to predictably produce. To speed up the process, Harvard researchers in a series of studies develop methods for efficiently identifying new materials that display topological properties.

The Wyss Institute has developed a sheet pile driving robot, Romu, that works in uneven terrain to build metal walls that can act as dams, retaining walls, or building foundations.

Harvard’s Climate Change Solutions Fund, now in its fifth year, is awarding seven research projects $1 million in grants.

A years-long effort by dozens of researchers at the Harvard-Smithsonian Center for Astrophysics reveals the first-ever image of a supermassive black hole.

Researchers at the Event Horizon Telescope (EHT) just unveiled the first-ever image of a black hole, which captures what EHT Director Sheperd Doeleman called “a one-way door from our universe.”

At Harvard, indigenous Alaskan elder Angaangaq Angakkorsuaq and Polynesian navigator Nainoa Thompson offered a close-to-the-earth perspective on climate change.

Using a statistical approach known as stylometry, which analyzes everything from the poem’s meter to the number of times different combinations of letters show up in the text, a team of researchers found new evidence that “Beowulf” is the work of a single author.

Researchers at Harvard Medical School’s Blavatnik Institute are developing an algorithm with information that is so complex, it will understand everything a first-year medical student knows.

For the past decade, scientist Greg Skomal and a team of researchers have been tagging and studying great white sharks off the Massachusetts coast. He hopes his work tracking the sharks’ movement, biology, and behavior will help shed light on the giant predators, help protection efforts, and perhaps reduce their encounters with humans.

Machine learning is an adaptive form of artificial intelligence that could allow physicians to use the collective wisdom of billions of medical decisions, patient cases, and outcomes to inform diagnosis and treatment.
