Q&A: La Nina's back and it's not good for parts of dry West

For the second straight year, the world heads into fall and winter with a La Nina weather event. This would tend to dry out parts of an already parched and fiery American West and boost an already busy Atlantic hurricane season.

For 50 years, mass incarceration has hurt American families. Here's how to change it

For nearly 50 years, the incarceration rate in the U.S. has grown at an exponential rate. Today, the U.S. has the largest prison population in the world. Incarceration is especially common in poor communities of color where nearly 70% of Black men who did not finish high school and are approaching midlife will be in prison at some point in their lives.

Facial recognition, cameras and other tools police use raise questions about accountability

Facial recognition, body cameras and other digital technologies are increasingly used by police departments, municipalities and even gated communities, but these tools manufactured by private companies raise the specter of unchecked surveillance, a University of California, Davis researcher suggests.

How bacteria create a piggy bank for the lean times

Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years ago. He saw big, dark splotches in the cells of the blue-green algae (cyanobacteria) he was studying without understanding either what they were or their purpose. Since then, scientists have realized that cyanophycin was made of a natural green biopolymer, that bacteria use it as a store of nitrogen and energy, and that it could have many biotechnological applications. They have tried producing large amounts of cyanophycin by putting the enzyme that makes it (known as cyanophycin synthetase) in everything from E. coli to tobacco, but without being able to make enough of it to be very useful.

Early modern human from Southeast Asia adapted to a rainforest environment

Although there has been evidence of our species living in rainforest regions in Southeast Asia from at least 70,000 years ago, the poor preservation of organic material in these regions limits how much we know about their diet and ecological adaptations to these habitats. An international team of scientists led by the Max Planck Institute for Evolutionary Anthropology in Leipzig and the Johannes Gutenberg University Mainz has now applied a new method to investigate the diet of fossil humans: The analysis of stable zinc isotopes from tooth enamel. This method proves particularly helpful to learn whether prehistoric humans and animals were primarily eating meat or plants.

Prince William tells space tourists: fix Earth instead

Britain's Prince William has launched an attack on space tourism, urging more attention on problems closer to home ahead of the COP26 climate summit.

Improvements in microscopy home in on biology's elusive details

In the late 1600s, the Dutch tradesman Anthoni van Leeuwenhoek began investigating the world of the very small using the first microscope, discovering a riotous world of protists, bacteria, and other previously unseen organisms. Subsequent generations of scientists have developed ever-more-sophisticated means of probing the microscopic world, bringing many mysteries of the biological realm into stunning relief.

After two hours, sunscreen that includes zinc oxide loses effectiveness, becomes toxic: study

Sunscreen that includes zinc oxide, a common ingredient, loses much of its effectiveness and becomes toxic after two hours of exposure to ultraviolet radiation, according to a collaboration that included Oregon State University scientists.
