Predicting the next pandemic virus is harder than we think

Posted: 20 Apr 2021 03:31 PM PDT

The observation that most of the viruses that cause human diseases come from other animals has led some researchers to attempt 'zoonotic risk prediction' to second-guess the next virus to hit us. However, in a new essay, experts propose that these zoonotic risk predictions are of limited value and will not tell us which virus will cause the next pandemic.

Deregulated US Government oversight on interstate waters leaves murky implications for states

Posted: 20 Apr 2021 01:09 PM PDT

Concern tends to ratchet up a notch when pollution enters the river runoff discussion on a national scale, specifically when smaller, navigable intrastate bodies of water push pollution into larger interstate waters often involved in commerce (i.e. the Mississippi River, Great Lakes, Ohio River).

'Dead clades walking': Fossil record provides new insights into mass extinctions

Posted: 20 Apr 2021 01:09 PM PDT

Mass extinctions are known as times of global upheaval, causing rapid losses in biodiversity that wipe out entire animal groups. Some of the doomed groups linger on before going extinct, and a team of scientists found these 'dead clades walking' (DCW) are more common and long-lasting than expected.

Fixed network of smartphones provides earthquake early warning in Costa Rica

Posted: 20 Apr 2021 10:10 AM PDT

Earthquake early warnings can be delivered successfully using a small network of off-the-shelf smartphones attached to building baseboards, according to a study conducted in Costa Rica last year.

A gene finding links severe canine juvenile epilepsy to mitochondrial dysfunction

Posted: 20 Apr 2021 09:15 AM PDT

Researchers found a cause for severe epilepsy resulting in death in Parson Russell Terrier puppies at a few months of age. A change in the PITRM1 gene can lead to a dysfunction of mitochondria, the cellular energy pumps. Concurrently, amyloid-beta accumulation and widespread neurodegeneration associated with Alzheimer's disease were identified in the puppies' brains. Changes to the PITRM1 gene in humans also cause a severe but slowly progressing brain disease.

Review summarizes known links between endocrine disruptors and breast cancer risk

Posted: 20 Apr 2021 09:15 AM PDT

Exposure to certain endocrine-disrupting chemicals could elevate the risk of breast cancer, according to a new comprehensive systematic review of epidemiological research. However, for many chemicals, evidence is inconsistent or still limited.

New catalyst for lower CO2 emissions

Posted: 20 Apr 2021 09:15 AM PDT

Perovskites have so far been used for solar cells, as anode materials or electronic components rather than for their catalytic properties. Now scientists have succeeded in producing a special perovskite that is excellently suited as a catalyst for converting CO2 into other useful substances, such as synthetic fuels. The new perovskite catalyst is very stable and also relatively cheap, so it would be suitable for industrial use.

Crucial action needed for coral reefs

Posted: 20 Apr 2021 09:14 AM PDT

An international group of scientific experts has stated the requirements for coral reef survival in a recent article. Over 500 million people rely on coral reefs.

Chickens and pigs with integrated genetic scissors

Posted: 20 Apr 2021 09:14 AM PDT

Genetically engineered animals provide important insights into the molecular basis of health and disease. Research has focused mainly on genetically modified mice, although other species, such as pigs, are more similar to human physiology. Researchers have now generated chickens and pigs in which target genes in desired organs can be efficiently altered.

Oceanographers reveal links between migrating Gulf Stream and warming ocean waters

Posted: 20 Apr 2021 09:14 AM PDT

The Northwest Atlantic Shelf is one of the fastest-changing regions in the global ocean, and is currently experiencing marine heat waves, altered fisheries and a surge in sea level rise along the North American east coast. A new article reveals the causes, potential predictability and historical context for these types of rapid changes.
