Millions of people struggle with insomnia, but the sleep disorder is now a solvable problem – and the most effective therapy might involve your smartphone rather than sleeping pills
Scientists identify a neuronal pathway in rats that drives ‘social grooming’, a behaviour that helps to hold animal communities together.
As high-level winds shift, heat and heavy rain can persist.

The trees that provide the raw material for chocolate have a higher yield when the groves are accessible to certain species.
A family tree of sea cows suggests that the dugong traversed an ocean to reach its present habitat.
Ground-based robots have potential for helping in the construction industry, but they are limited by their height. In this week’s issue, Mirko Kovac, Robert Stuart-Smith and their colleagues introduce highly manoeuvrable aerial robots that can perform additive 3D construction tasks. Inspired by natural builders such as wasps and bees, the researchers created BuilDrones (as shown on the cover) that can work in an autonomous team to perform 3D printing tasks using foam- or cement-based materials. They also created ScanDrones to assess the quality of the structures
being built. The team hopes that this approach of ‘aerial additive manufacturing’ could help to build structures in difficult to access areas.
Biomarkers are measurable indicators of what’s happening in your body. They can be found in blood, other body fluids, organs, and tissues, and can be used to track healthy processes, disease progression, or even responses to a medication. Biomarkers are an important part of dementia research.

The vaccine, called Convidecia Air, changes the liquid form of the vaccine into an aerosol using a nebuilzer. The vaccine can then be inhaled through the mouth using the nebulizer machine. The needle-free vaccine “can effectively induce comprehensive immune protection in response to SARS-CoV-2 after just one breath,” Cansino said in a statement.
Fortune.com on September 5, 2022 – China’s government approved the world’s first inhaled vaccine against COVID-19, the vaccine’s maker Cansino Biologics announced on Sunday.
In July, Chinese scientists published a pre-print study showing that people who received one booster dose of Cansino’s inhaled vaccine after two doses of the inactivated jab from Chinese maker Sinovac developed more antibodies than people who received three Sinovac shots. Four weeks after receiving the inhaled booster, 92.5% of people had developed neutralizing antibodies for Omicron.
Those who got three doses on Sinovac’s jab did not demonstrate any neutralizing antibodies for Omicron, either four weeks or six months after getting a booster.
On this week’s show: The U.S. government is partnering with academics to speed up the search for more than 80,000 soldiers who went missing in action, and how humans create their own “oxidation zone” in the air around them.
First up on the podcast this week, Tess Joosse is a former news intern here at Science and is now a freelance science journalist based in Madison, Wisconsin. Tess talks with host Sarah Crespi about attempts to use environmental DNA—free-floating DNA in soil or water—to help locate the remains of soldiers lost at sea. Also featured in this segment:
University of Wisconsin, Madison, molecular biologist Bridget Ladell Woods Hole Oceanographic Institution marine biologist Kirstin Meyer-Kaiser
Also this week, Nora Zannoni, a postdoctoral researcher in the atmospheric chemistry department at the Max Planck Institute for Chemistry, talks about people’s contributions to indoor chemistry. She chats with Sarah about why it’s important to go beyond studying the health effects of cleaning chemicals and gas stoves to explore how humans add their own bodies’ chemicals and reactions to the air we breathe. In a sponsored segment from Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for Custom Publishing, interviews Benedetto Marelli, associate professor at MIT, about winning the BioInnovation Institute & Science Prize for Innovation and how he became an entrepreneur.
