Much of common pharmaceutical development today is the product of laborious cycles of tweaking and optimization. In each drug, a carefully concocted formula of natural and synthetic enzymes and ingredients works together to catalyze a desired reaction. But in early development, much of the process is spent determining what quantities of each enzyme to use to ensure a reaction occurs at a specific...

Prime Minister Justin Trudeau will announce stepped up efforts to reduce Canada's carbon footprint when he meets other world leaders at a virtual climate summit hosted by US President Joe Biden this week, a media report said Wednesday.

When marine biologist Eleanor Caves of the University of Exeter thinks back to her first scuba dives, one of the first things she recalls noticing is that colors seem off underwater. The vivid reds, oranges, purples and yellows she was used to seeing in the sunlit waters near the surface look increasingly dim and drab with depth, and before long the whole ocean loses most of its rainbow leaving...

When deciding whether to have children, there are many factors to consider: finances, support systems, personal values. For a growing number of people, climate change is also being added to the list of considerations, says a University of Arizona researcher.

We've all heard the news stories of how what you eat can affect your microbiome. Changing your diet can shift your unique microbial fingerprint. This shift can cause a dramatic effect on your health. But what about the microbiome of the plants you eat? Scientists are beginning to see how shifts in plant microbiomes also impact plant health. Unlocking the factors in plant microbial assemblage can...

UC Riverside engineers are developing methods to estimate the impact of California's destructive wildfires on air quality in neighborhoods affected by the smoke from these fires. Their research, funded by NASA and the results published in Atmospheric Pollution Research, fills in the gaps in current methods by providing air quality information at the neighborhood scales required by public health...

In nature, many molecules possess a property called chirality, which means that they cannot be superimposed on their mirror images (like a left and right hand).

It's a common sight: pelicans gliding along the waves, right by the shore. These birds make this kind of surfing look effortless, but actually the physics involved that give them a big boost are not simple.

Like humans, certain plants are treated with antibiotics to ward off pathogens and protect the host. Saving millions, antibiotics are one of the 20th century's greatest scientific discoveries, but repeated use and misuse of these life-saving microbial products can disrupt the human microbiome and can have severe effects on an individual's health. Overuse has led to several microbes developing...

Women who experience partner violence at a young age don't always show physical signs of abuse and don't always disclose—or recognize—the dangerous position they're in. A new study from Michigan State University is one of the first to examine multiple factors that influence young women's disclosure of partner violence that occurred during their first relationships, when they were just under 15...

A national strategy to ensure that families have access to food could revolutionize Canada's farms, according to a new study from Simon Fraser University's Food Systems Lab. The study proposes implementing a "right to food" framework that would support the needed funding, infrastructure, and stability that can reduce losses of edible food at the farm, while creating better access to local foods...

The milestone, which the MOXIE instrument achieved by converting carbon dioxide into oxygen, points the way to future human exploration of the Red Planet.

Scientists detect small pockets of carbon dioxide-rich liquid water in a meteorite dating from the early solar system.

Researchers have found that artificial intelligence algorithms can influence people's preferences for fictitious political candidates or potential romantic partners, depending on whether recommendations were explicit or covert.

When air quality in China is poor, locally reported air pollution measurements diverge from U.S. embassy-reported measurements more than would be expected by random chance, finds an analysis of air pollution data from five large Chinese cities.

Researchers have found out that ultrafast switches in material properties can be prompted by laser pulses -- and why. This knowledge may enable new transistor concepts.

Researchers from the Physical Chemistry Department of the Fritz Haber Institute and the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg have found out that ultrafast switches in material properties can be prompted by laser pulses—and why. This knowledge may enable new transistor concepts.
