Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales. A recent study quantified the lipid content in Fraser River Chinook salmon -- the southern resident's preferred meal -- and found that spring-run Chinook salmon, the earliest to arrive to the...
New antioxidants found in beef, chicken, and pork
Scientists found that 2-oxo-imidazole-containing dipeptides (2-oxo-IDPs) exhibit very high antioxidant activity. Furthermore, they established a method to selectively and sensitively detect very small amounts of 2-oxo-IDPs and revealed for the first time that several types of 2-oxo-IDPs are contained in meat, including beef, pork, and chicken.
Feedback loops make climate action even more urgent, scientists say
Researchers have identified 26 global warming accelerators known as amplifying feedback loops that the researchers say aren't being properly included in climate models. They note that the findings add urgency to the need to respond to the climate crisis and provide a roadmap for policymakers aiming to avert the most...
How to pull carbon dioxide out of seawater
Researchers may have found the key to a truly efficient and inexpensive mechanism for removing carbon dioxide from seawater. The method could be far more efficient than existing systems for removing the greenhouse gas from the air.
Newly discovered virus can kill resistant bacteria
A Danish creek has surprised researchers by containing previously unknown virus species.
Using spiders as environmentally-friendly pest control
Groups of spiders could be used as an environmentally-friendly way to protect crops against agricultural pests. That's according to new research which suggests that web-building groups of spiders can eat a devastating pest moth of commercially important crops like tomato and potato worldwide.
Before global warming, was the Earth cooling down or heating up?
A review article addresses a conflict between models and evidence, known as the Holocene global temperature conundrum.
How the fastest fish hunts its prey
Scientists have designed a novel electronic tag package incorporating high-tech sensors and a video camera in order to document a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.
Microbes play a key role in unleashing ‘forever chemicals’ from recycled-waste fertilizer
'Forever chemicals' are everywhere -- water, soil, crops, animals, the blood of 97% of Americans -- researchers are trying to figure out how they got there. Their recent findings suggest that the microbes that help break down biodegradable materials and other waste are likely complicit in the release of the...
Antibiotic consumption is currently not the main driver of aminoglycoside resistance spread, study suggests
The spread of antibiotic resistance, where infectious bacteria are able to defeat the drugs intended to kill them, may not be primarily driven by antibiotic consumption, according to a new study.
