Recent theories suggesting that half of fishes’ food comes from from land-based ecosystems may not hold water. Experiments show that algae, not land-based matter, is needed to build healthy and fertile aquatic organisms.

New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions. The study shows that bacterial communities in the six rivers shifted synchronously over time, correlating with seasonal shifts in hydrology and biogeochemistry.

Richer nations with competitive crop production and few trade barriers would fare the best if climate change, weather events or other factors cause yields of grain and oilseed crops to become more volatile, a new study has found.

Mammals have evolved a complex system for controlling bone remodeling. Babies require calcium for healthy bones and they obtain it from their mother’s milk. Nursing mothers release calcium from their bones. Surprisingly, however, the same system also plays a key part in the control of fever and of female body temperature.

Researchers have identified a set of molecular brakes that stabilize the developing brain’s circuitry. Moreover, experimentally removing those brakes in mice enhanced the animals’ performance in a test of visual learning, suggesting a long-term path to therapeutic application.

Men who regularly take part in moderate-to-heavy intensity exercise such as jogging, tennis or swimming may be less likely to have a stroke than people who get no exercise or only light exercise, such as walking, golfing, or bowling, according to a new study.

In the first video showing the auroras above the northern latitudes of Saturn, Cassini has spotted the tallest known “northern lights” in the solar system, flickering in shape and brightness high above the ringed planet.

A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals. The new approach, pioneered by bioengineers and immunologists, uses plastic disks impregnated with tumor-specific antigens and implanted under the skin to reprogram the mammalian immune system to attack tumors.
