A simple material can separate carbon dioxide from other gases that fly out of the smokestacks of coal-fired power plants. It lacks the shortcomings that other proposed carbon filtration materials have, rivaling designer compounds in its simplicity, overall stability and ease of preparation.
Bacterial sensors send a jolt of electricity when triggered
Scientists and engineers have developed programmable bacteria that sense contaminants and release an electronic signal in real time.
Climate change could trigger the Congo peatlands to release billions of tons of carbon
New research reveals that the world's largest tropical peatland turned from being a major store of carbon to a source of damaging carbon dioxide emissions as a result of climate change thousands of years ago. Around the time that Stonehenge was built, 5,000 years ago, the climate of central Congo...
Why fish look down when they swim
New simulations show that fish look downward when they swim because the stable riverbed below them provides more reliable information about their swimming direction and speed.
Photosynthesis: Auxiliary factor ensures efficient energy production
Biologists demonstrate how the auxiliary factor CGL160 contributes to the synthesis of crucial parts of the photosynthetic machinery.
Cracking the enigma of how plant sperm is compacted
A research team have discovered a mechanism of flowering plant sperm compaction and gathered clues as to why it is required.
Male and female travelers’ ‘transformations’
A new study has revealed men and women experience change while travelling in similar ways. Consumers are increasingly seeking activities that help them achieve new levels of enrichment and since the lift of COVID-19 travel restrictions, they are more conscious of the value they want to gain from their holidays.
Rare and iconic Atala butterflies retain an ancient pattern of wing symmetry
A new study helps bring the incredible color and pattern variation in butterflies into focus. The results align with a growing body of evidence that suggests butterfly-wing diversity really boils down to just a few simple ingredients in an ancient recipe that's stood the test of time.
A new control system for synthetic genes
Using an approach based on the CRISPR gene-editing system, researchers developed a way to precisely control the amount of a particular protein that is produced in mammalian cells.
More than one way to build a black bird
For a species of flycatcher in the remote Solomon Islands, scientists have so far found at least two genetic pathways leading to the same physical outcome: all-black feathers. This change was no random accident. It was a result of nature specifically selecting for this trait.
