A new study has found humpback whales sing louder when the wind is noisy, but don't have the same reaction to boat engines.
Evidence of Ice Age human migrations from China to the Americas and Japan
Scientists have used mitochondrial DNA to trace a female lineage from northern coastal China to the Americas. By integrating contemporary and ancient mitochondrial DNA, the team found evidence of at least two migrations: one during the last ice age, and one during the subsequent melting period. Around the same time...
Kangaroo Island ants ‘play dead’ to avoid predators
They're well known for their industrious work, but now a species of ant on Kangaroo Island is also showing that it is skilled at 'playing dead', a behavior that researchers believe is a recorded world first.
Viruses could reshuffle the carbon cycle in a warming world
The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and...
Cleanup of inactive Gulf of Mexico wells estimated at $30 billion
A new article examines the cost to plug 14,000 wells that are inactive, have not produced for five years and are unlikely to be reactivated in the Gulf of Mexico region, which is the epicenter of U.S. offshore oil and gas operations.
Scientists develop gene silencing DNA enzyme that can target a single molecule
Researchers have developed a DNA enzyme -- or DNAzyme -- that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough 'gene silencing' technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.
Tiny microbes could brew big benefits for green biomanufacturing
Scientists find new route in bacteria to decarbonize industry. The discovery could reduce greenhouse gas emissions from the manufacturing of fuels, drugs, and chemicals. A research team has engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.
New probe aids novel findings on cell functions
New research shows the use of a new cellular probe helped discover new findings about certain cellular processes.
T cells can activate themselves to fight tumors
Scientists find an auto-signaling mechanism driving the T cell anti-tumor response; findings may inspire new cancer therapeutics and biomarkers.
Researchers close to unleashing rapeseed’s protein power for human consumption
Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study, researchers have gotten closer to removing the plant's bitter substances, and in...
