Geckos know their own odor
Geckos can use their tongue to differentiate their own odor from that of other members of their species, as researchers have shown in a new experimental study. The findings show that geckos are able to communicate socially, meaning that they are more intelligent than was previously assumed.
Food quality matters for southern resident killer whales
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 Technology Revolutionizes the Analysis of Old Ice
Ice cores are a unique climate archive. Thanks to a new method developed by researchers at the University of Bern and Empa, greenhouse gas concentrations in 1.5 million year old ice can be measured even more accurately.
Using Combustion to Make Better Batteries
An MIT team is working to harness combustion to yield valuable materials, including some that are critical in the manufacture of lithium-ion batteries.
Hazel Dormice Should Be Classified as ‘Endangered’, According to New Research
New research has highlighted issues about how the conservation status of different species is classified, and suggests the focus should be on restoring species now rather than waiting for them to become threatened with extinction before acting.
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...
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.
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.
