If humans could hijack photosynthesis — essentially, plants’ food factory — they could, in theory, capture carbon and produce hydrogen, both potentially helpful in fighting climate change. Absorbing carbon could slow climate change, and manufacturing hydrogen efficiently could create an alternative to CO2-producing fossil fuels.Figuring Out How to Harness PhotosynthesisPlants’ natural “factory” is both elegant and efficient: they absorb energy from the sun to process carbon dioxide a ...read more
When it comes to good overall health, the teeth are often overlooked. We tend to think of teeth as primarily cosmetic when in reality, oral health is linked to physical health and the risk of a number of chronic conditions.

Bacteria can travel from areas like infected gums through the bloodstream to other parts of your body,” says Shash ...read more
Climate change has already begun to alter the environment in many ways, but scientists are also vigilantly watching for the ripple effects that will spread to human health. Now, they’re raising the alarm about exposure to viruses lingering in sewage as the world gears up for more frequent storms this century. A new study published in the journal Water Research warns of virus transmission through sewage systems, a public health risk that could grow in severity as wastewater continues to spill ...read more

After discovering fossilized facial bones in Spain, researchers now say they’ve found the oldest face of Western Europe.In 2022, researchers with the Atapuerca Project uncovered facial bones from an early human ancestor at the Sima del Elefante site (Sierra de Atapuerca, Burgos) in northern Spain. The fossil date ranges from 1.1 million years to 1.4 million years old. After detailed study, researchers announced that the facial bones were not that of Homo antecessor, but of a different hominin. ...read more
