New research investigates how wing design, wing flexibility, power, and the role of legs influence successful aerial-aquatic locomotion. Such versatile, affordable machines could one day monitor water quality or inspect infrastructure, reaching locations that were previously inaccessible using conventional vehicles.

The bacteria that live in our bodies, particularly our guts, play key roles in immunity and development. But babies born by cesarean section don't get the rich blend of microbes that come from a vaginal birth—microbes that may help prevent disorders such as asthma and allergies. A 2020 study suggests feeding these infants a small amount of their mothers' feces could "normalize" their gut microbiome—the ecosystem of bacteria, viruses, and fungi in the digestive system—and possibly give their immune systems a healthier start.

Biologically immortal sea cucumber tissues may provide new opportunities for ethical aging research in regenerative biology, biomedical research, and tissue engineering. Learn more in @ScienceAdvances: scim.ag/4ozyKIp

Research finds that the ovaries of old mice become infiltrated with immune cells and may secrete immune signals into the body. The consequences of these changes aren’t clear, but a similar transformation in humans could have health implications after menopause. Learn more: scim.ag/4grQaoD

Researchers in Science have analyzed ancient DNA extracted from 4th to 6th century CE burials at archaeological sites in the Little Hungarian Plain along the Danube River to get a closer look at population and political shifts in the region after the fall of the Roman Empire.

New research in @SciSignal reveals how a pair of immune signaling proteins acts to protect cancer cells from cell death induced by cytotoxic T cells by countering the inflammatory effects of the cytokine interferon-γ. scim.ag/4fjP6C5

Using the Curiosity rover, researchers found stones composed of native sulfur in Gediz Vallis, within Gale crater on Mars. The researchers propose in Science that the primary source of this sulfur was magmatic vapor, which cooled in the near subsurface cryosphere and was released by decompression during the erosion of Gediz Vallis. scim.ag/44N9ENb

Homing pigeons orient themselves by the Sun’s position under sunny skies and rely on their magnetic sense when it is cloudy. Under overcast conditions, homing pigeons with their normal liver macrophages had little issue flying a 19-kilometer route for which they had been trained. When injected with clodronate liposomes that knocked out the liver macrophages, the pigeons could navigate the route without issue when it was sunny. Under overcast skies, however, homing pigeons with depleted liver macrophages struggled mightily to find their way home—suggesting the immune cells play a role in the birds’ magnetic sense.
