Stronger coffee with fewer coffee beans (link is external)

Environmental Feed -

Researchers have worked to optimize the use of coffee grounds in pour-over coffee. They recommend pouring from as high as possible while still maintaining the water's flow. In particular, the group found the thick water jets typical of standard gooseneck kettles are ideal for achieving this necessary height and laminar flow. Displaced grounds recirculate as the water digs deeper into the coffee bed, allowing for better mixing between the water and the grounds, and thus, results in a stronger coffee with fewer beans.

Rain barrel basics: Conserving water but not mosquito habitats (link is external)

Environmental Feed -

Researchers surveyed residential rain barrels to determine how often mosquitoes took up residence in rain barrels and what preventative measures would most effectively keep mosquitoes out. Taking these preventative measures will reduce potential health risks and ensure that rain barrels remain a safe, effective, and environmentally sustainable tool for managing stormwater runoff.

Researchers discover why plastic sheds dangerous fragments (link is external)

Environmental Feed -

The world is littered with trillions of micro- and nanoscopic pieces of plastic. These can be smaller than a virus -- just the right size to disrupt cells and even alter DNA. Researchers find them almost everywhere they've looked, from Antarctic snow to human blood. In a new study, scientists have delineated the molecular process that causes these small pieces to break off in such large quantities.

The lush past of the world's largest desert (link is external)

Environmental Feed -

The vast desert of the Arabian Peninsula was not always an arid landscape. A recent study reveals that this region was once home to a vast lake and river system. These favorable conditions fostered grasslands and savannahs, enabling human migration -- until drought returned, forcing populations to move. This research highlights the impact of climate cycles on landscapes and human societies.

Best methods for growing Atlantic sea scallops (link is external)

Environmental Feed -

A new study compares two scallop farming methods, ear-hanging and lantern net culture, over a complete grow-out cycle to determine which approach yields the best results for commercial growers. The study found that scallops grown with ear-hanging culture had slightly larger shell heights, about 1-4% greater than those in lantern nets. More significantly, ear-hanging scallops had up to 12% more adductor muscle weight. Researchers also found that ear-hanging scallops grew more quickly in optimal conditions, which are between 50 and 59 degrees Fahrenheit, but were more affected by colder winter temperatures than those in lantern nets.

Oxygen is running low in inland waters, and humans are to blame (link is external)

Environmental Feed -

Rivers, streams, lakes, and reservoirs aren't just scenic parts of our landscape -- they're also vital engines for life on Earth. These inland waters 'breathe' oxygen, just like we do. But a new study shows that we've been suffocating them during the last century, an era also known as the Anthropocene. The research reveals that the way oxygen is produced and used in inland waters has dramatically changed since 1900. The culprit? Human activities.

Planetary health diet and Mediterranean diet associated with similar survival and sustainability benefits (link is external)

Environmental Feed -

A cohort study was conducted in Spain to compare the health and environmental benefits of the Planetary Health Diet (PHD) and the Mediterranean Diet. Compared to participants with low adherence, higher adherence to both diets was similarly associated with lower all-cause mortality and with comparable low environmental impact. This study highlights the advantages of the plant-based diets, with wider adoption of healthy and sustainable diets needed to prevent excess premature deaths worldwide.

Novel genomic screening tool enables precision reverse-engineering of genetic programming in cells (link is external)

Environmental Feed -

Collaborative research defines a novel approach to understanding how certain proteins called transcription factors determine which genetic programs will drive cell growth and maturation. The method, called 'Perturb-multiome,' uses CRISPR to knock out the function of individual transcription factors across many blood cells at once. The researchers then perform single-cell analyses on each cell to measure the effects of the editing, including identifying which genes have been turned on or off and which genes are accessible (based on epigenetic markers).

Century-old clues reveal hidden threat to Australian songbird (link is external)

Environmental Feed -

A hidden threat facing one of Australia's most iconic birds has been uncovered in a new study. The critically endangered regent honeyeater once numbered in the hundreds of thousands, but their population has dwindled to fewer than 300. By analysing the DNA of museum specimens more than 100 years old and comparing it to modern samples, the team discovered that despite a population decline of 99 per cent, this has not been entirely mirrored by genetics. The bird has lost 9 per cent of its genetic diversity.
