Hydrogen, a clean fuel, is incredibly dense in energy -- three times more than diesel or gasoline. Its ability to power a sustainable future has been hindered by a lack of high performing catalysts. Now, a collaborative research group has developed nanoporous molybdenum-based intermetallic compounds that could address this conundrum.
Attack on 2 fronts leads ocean bacteria to require carbon boost
The types of ocean bacteria known to absorb carbon dioxide from the air require more energy -- in the form of carbon -- and other resources when they're simultaneously infected by viruses and face attack from nearby predators, new research has found.
Wastewater testing expected to work for most infectious diseases
Wastewater surveillance of infectious diseases is expected work for just about every infectious disease that affects humans, including monkeypox and polio. But more research is needed to apply the science for public health benefit, according to a research team led by epidemiologists.
Differences in male and female ostriches could explain how they form groups
Males and females are affected in different ways by cooperation and competition in social groups -- something that could determine which group sizes work best. According to a new study, this depends to a large extent quite simply on females and males having different interests.
Artificial intelligence answers the call for quail information
When states want to gauge quail populations, the process can be grueling, time-consuming and expensive. It means spending hours in the field listening for calls. Or leaving a recording device in the field to catch what sounds are made -- only to spend hours later listening to that audio. Then,...
Isotope data strengthens suspicions of ivory stockpile theft
A new study uses carbon isotope science to show that marked tusks in a seized ivory shipment were more than 30 years old and likely had found their way from a guarded government stockpile into the hands of illegal ivory traders. The results suggest that governments that maintain ivory stockpiles...
Impact of coral chemical compounds on reef composition and health
Stumbling upon a new source of underwater caffeine was just an added bonus of a new study examining the impact of chemical compounds that corals release into the seawater.
High exposure to glyphosate in pregnancy could cause lower birth weights in babies
Researchers are learning more about the effects of herbicide exposure during pregnancy.
New analysis of obsidian blades reveals dynamic Neolithic social networks
An analysis of obsidian artifacts excavated during the 1960s at two prominent archaeological sites in southwestern Iran suggests that the networks Neolithic people formed in the region as they developed agriculture are larger and more complex than previously believed. The study has applied state-of-the-art analytical tools to a collection of...
Economic losses from hurricanes become too big to be offset by the US if warming continues
Hurricane damages can increase due to increasing global temperatures, caused by greenhouse gas emissions from fossil fuels. Computer simulations of regional economic sectors and supply chains in the US now show that the resulting economic losses can at some point not be nationally offset under unabated warming. If too many...
