In a randomized trial of 236 adults with Ph-positive acute lymphoblastic leukemia, a regimen with no chemotherapy had higher event-free survival at 24 months than imatinib plus chemotherapy, 86% against 67%. Here is what the trial shows, why overall survival differs by less, and what is still open.
Nine private funders announced the Species Recovery Alliance at COP17, committing more than $500 million over five years to species classed as extinct in the wild, critically endangered, or endangered. Here is what the pledge covers, how it sits beside total nature funding, and what the sources do not yet say.
MIT engineers coated lipid nanoparticles with antibody fragments to deliver mRNA to natural killer cells inside living mice, reprogramming about 80 percent of targeted cells. The cells worked against melanoma, T cell lymphoma, and autoimmune hepatitis. The article covers why making cell therapy inside the body could cut cost and time, and why mouse results are not yet proof for people.
A University of Sydney review of more than 70 studies of conservation success found three shared conditions: local knowledge valued alongside science, communities central in decision-making, and management adapted to local conditions. The article covers cases from Papua New Guinea, West Africa, Canada, and Tasmania, and the limits of a review of published successes.
Two Scripps Institution of Oceanography field studies found that playing healthy reef sounds underwater raised coral settlement near the speaker and drew four to 14 times more fish larvae. The article covers the living-coating and 3D-printed structure results, the limits of the effect, and the $22 million Kalaeloa Hybrid Reef planned off O'ahu.
Henri Kagan, 95, and Kenso Soai, 76, won the 2026 Nobel Prize in Chemistry for work on mirror-image molecules. The article covers Kagan's 1986 discovery, Soai's 2003 reaction, the 2001 omission that preceded this prize, and the open question of why life uses one handedness.
Francis Halzen won the 2026 Nobel Prize in Physics for the IceCube Neutrino Observatory, a cubic kilometer of Antarctic ice that catches particles from deep space. The article covers the 38 years from his 1988 sketch to the prize, the collaboration behind it, and the cost and credit questions it raises.
Biscayne Bay, the shallow urban water beside Miami, has been named an Important Shark and Ray Area after 10 years of University of Miami research. The article covers what the designation recognizes, what it does not protect, and how the bay's health compares.
The 2026 Nobel Prize in Physiology or Medicine recognizes three scientists behind optogenetics, which lets researchers switch specific nerve cells on and off with light. The article covers what it made possible for brain research and patients, and states its limits plainly.
A UCLA and Ewha Womans University study converted mixed, unsorted plastic into hydrogen of more than 90% purity, with over 75% of the carbon kept in carbonates or liquid residues. The work is still at laboratory scale, and the authors say its economic viability has yet to be evaluated.
Ninh Binh Province has created a 3,182-hectare reserve for the Delacour's langur, a Critically Endangered monkey found only in Vietnam. A 2022 to 2025 survey counted 562 to 570 of them, though quarrying and hunting remain documented threats.
HALO Trust has concluded 27 years of humanitarian landmine clearance in Kosovo. The cleared land now underpins a $14 billion economy, and the deminers who did the work are now training teams in Syria and Ukraine, even as several European nations exit the treaty that enabled this mission.
Scientists long worried that carbon released by thawing Arctic permafrost would speed up warming. A new measurement study off Canada's Herschel Island shows the seafloor buries about 90 percent of the carbon that reaches it. German and Canadian-based research teams say the finding gives climate models real numbers where they once used guesses.
Scientists have created a plastic with a built-in off switch: dormant bacteria that wake up on command and dissolve the material completely within six days, leaving no microplastics behind. It's an example of a durability problem reimagined as a design opportunity.
University of Rochester scientists have developed a solar-powered desalination device that produces fresh drinking water from seawater with zero brine waste, and can even extract lithium for batteries. Tested on three oceans, it could transform access to clean water worldwide.
MIT researchers found that cysteine, an amino acid in everyday foods, activates a natural immune pathway that helps the gut rebuild itself. The Nature-published discovery could transform recovery for cancer patients worldwide.
In the most sweeping advance against malaria in history, WHO-recommended vaccines are now rolling out across 25 African countries, 47 nations have been certified malaria-free, and a new $2.99-per-dose pricing deal aims to protect 50 million more children by 2030.
A Japan-Germany research team achieved roughly 130% quantum yield in solar energy generation using a spin-flip metal complex, with a theoretical ceiling that may reach 200%.
