Lake ecosystems: Nitrogen has been underestimated      (via sciencedaily.com)     Original source 

An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. The result: increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish kills. Until now, controls in lake management have focused primarily on phosphorus inputs to counteract this effect. Now, this dogma is shaken by a study showing that nitrogen is also a critical driver for phytoplankton growth in lakes worldwide.

Small dietary changes can cut your carbon footprint by 25%      (via sciencedaily.com)     Original source 

New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.

A new plant's name that tells a story      (via sciencedaily.com)     Original source 

A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.

Want fewer microplastics in your tap water? Try boiling it first      (via sciencedaily.com)     Original source 

Nano- and microplastics are seemingly everywhere -- water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.

Nanocarrier with escape reflex      (via sciencedaily.com)     Original source 

Protein-based drugs must be transported into cells in a way that prevents their immediate degradation. A new approach is intended to ensure that they remain intact only in certain cells, such as cancer cells. A Japanese research team has introduced a nanocarrier that can 'escape' from endosomes before its cargo is destroyed there. This ability to escape is only triggered within the endosomes of certain tumor cells.

Walleye struggle with changes to timing of spring thaw      (via sciencedaily.com)     Original source 

Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the Midwestern United States and Canada. According to a new study, part of the problem is that walleye are creatures of habit, and the seasons -- especially winter -- are changing so fast that this iconic species of freshwater fish can't keep up.

You may be breathing in more tiny nanoparticles from your gas stove than from car exhaust      (via sciencedaily.com)     Original source 

Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new study has found.

Low-Temperature Plasma used to remove E. coli from hydroponically grown crops      (via sciencedaily.com)     Original source 

In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.

Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins      (via sciencedaily.com)     Original source 

Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.

Common plant could help reduce food insecurity      (via sciencedaily.com)     Original source 

An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air -- making it a valuable green fertilizer -- and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study suggests.

Biomolecular condensates -- regulatory hubs for plant iron supply      (via sciencedaily.com)     Original source 

Iron is a micronutrient for plants. Biologists now show that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light -- an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into 'biomolecular condensates' in the cell nucleus shortly after this exposure.

Altering the circadian clock adapts barley to short growing seasons      (via sciencedaily.com)     Original source 

To ensure that plants flower at the right time of year, they possess an internal clock, which enables them to measure the amount of daylight during a day. Biologists now describe that the mutation of a specific gene makes the flowering time of barley almost entirely independent of day length. This mutation can be useful for breeding varieties adapted to altered climatic conditions with relatively mild winters and hot, dry summers.

Graphene research: Numerous products, no acute dangers found by study      (via sciencedaily.com)     Original source 

Graphene is an enormously promising material. It consists of a single layer of carbon atoms arranged in a honeycomb pattern and has extraordinary properties: exceptional mechanical strength, flexibility, transparency and outstanding thermal and electrical conductivity. If the already two-dimensional material is spatially restricted even more, for example into a narrow ribbon, controllable quantum effects can be created. This could enable a wide range of applications, from vehicle construction and energy storage to quantum computing.

New water batteries stay cool under pressure      (via sciencedaily.com)     Original source 

A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.

An environmentally friendly way to turn seafood waste into value-added products      (via sciencedaily.com)     Original source 

Reduce, reuse, recycle, and repurpose: These are all ways we can live more sustainably. One tricky aspect of recycling, though, is that sometimes the recycling process is chemically intensive, and this is the case for recycling one of the world's most abundant materials -- chitin. Researchers have tackled this problem and found a way to sustainably recover chitin from seafood waste.
