Host Andres Almeida: Image data from Earth-observing satellites like Landsat and the PACE mission helps scientists monitor everything from wildfires and hurricanes to crop health and changing coastlines. But before scientists can use those images for research, the data must be carefully calibrated to ensure the measurements are accurate and consistent over time. A lot of this happensContinue Reading

When an animal’s environment changes faster than the animal can adapt, its chances of survival can flat-line. The same is true for populations, and even entire species. Now, scientists at MIT and the University of Leicester have found that this connection between evolutionary adaptation and the pace of environmental changeContinue Reading

A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after being isolated for roughly 20,000 years. Surprisingly, despite their small population,Continue Reading

The head of the UN’s civil aviation agency, ICAO, has called for immediate global action to protect commercial flights from escalating military threats, including missiles, drones, and GPS signal jamming.Continue Reading
In 2022, global production of construction materials accounted for more than 7 percent of total carbon emissions. But how many of those materials were truly necessary to build houses, buildings, and bridges? A technique called topology optimization can design structures that reduce the amount of material used, in some casesContinue Reading
