If we can't untangle this mess, Norway's blue industry will never be green      (via sciencedaily.com)     Original source 

For the first time, researchers have investigated how ropes and fishing lines are handled by the Norwegian commercial fishing industry. The fishing fleet loses almost 400 tons of rope in Norwegian waters every year.

New trial highlights incremental progress towards a cure for HIV-1      (via sciencedaily.com)     Original source 

A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far -- researchers have come to developing a cure for HIV-1.

Why do flies fall in love? Researchers tease out the signals behind fruit fly courtship songs      (via sciencedaily.com)     Original source 

Researchers have pinpointed the group of neurons in the nerve cord -- a structure analogous to our spinal cord -- that produce and pattern the fly's two major courtship songs. They've also measured neuronal activity in these cells while flies were singing to understand how these neurons control each type of song.

Polar bears unlikely to adapt to longer summers      (via sciencedaily.com)     Original source 

More time stranded on land means greater risk of starvation for polar bears, a new study indicates. During three summer weeks, 20 polar bears closely observed by scientists tried different strategies to maintain energy reserves, including resting, scavenging and foraging. Yet nearly all of them lost weight rapidly: on average around 1 kilogram, or 2.2 pounds, per day. Some have speculated that polar bears might adapt to the longer ice-free seasons due to climate warming by acting like their grizzly bear relatives and either rest or eat terrestrial food. The polar bears in this study tried versions of both strategies -- with little success.

Compounds released by bleaching reefs promote bacteria, potentially stressing coral further      (via sciencedaily.com)     Original source 

New research revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.

Nutrients direct intestinal stem cell function and affect aging      (via sciencedaily.com)     Original source 

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the aging gut.

Global deforestation leads to more mercury pollution      (via sciencedaily.com)     Original source 

Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.

Researchers unveil method to detect 'forever chemicals' in under 3 minutes      (via sciencedaily.com)     Original source 

PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.

'Legacy' phosphorus delays water quality improvements in Gulf of Mexico      (via sciencedaily.com)     Original source 

The same phosphorus that fertilizes the thriving agriculture of the Midwest is also responsible for a vast 'dead zone' in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked -- and lingering -- problem.

Ancient rocks improve understanding of tectonic activity between earthquakes      (via sciencedaily.com)     Original source 

Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.

Replacing animal-based foods with alternative proteins would unlock land for carbon removal      (via sciencedaily.com)     Original source 

Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.

New research uncovers biological drivers of heart disease risk      (via sciencedaily.com)     Original source 

Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.

New study sheds new light on forests' role in climate and water cycle      (via sciencedaily.com)     Original source 

Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.

Inexpensive, carbon-neutral biofuels are finally possible      (via sciencedaily.com)     Original source 

When it comes to making fuel from plants, the first step has always been the hardest -- breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.

New approach to tackling bacterial infections identified      (via sciencedaily.com)     Original source 

Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.
