Engineers devise a modular system to produce efficient, scalable aquabots
Researchers developed a new approach to building deformable underwater robots, using simple repeating substructures. The team demonstrated the new system in two different example configurations, one like an eel and the other a wing-like hydrofoil.
Will revitalizing old blood slow aging?
Young blood may be an elixir for older bodies, rejuvenating aging hearts, muscles, and brains. But how can old blood become young again? Stem cell scientists may have found a way.
Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time
New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by envi…
Loss of reptiles poses threat for small islands where humans may have caused extinctions
A new examination of ancient and current species of reptiles conducted by paleobiologists reveals the serious impact of the disappearance of even a few species of reptiles in some island areas. The study has startling conclusions about how, on smaller …
‘Thrifty’ low-energy budgets of primary cancer tumors quantified
In five different types of cancers, researchers found that tumors were successful at proliferating on low-energy budgets in part because they neglect normal tissue functions that healthy organs carry out for the benefit of the body as a whole. The disc…
How the ‘construction site’ of long term memory gets built in the brain
The proteins responsible for forming memories in neurons change depending on experience, a hint at how our brains build memory.
