Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal transmitter for light-dependent root architecture.

A group of world leading health and scientific experts are calling on the aviation industry to take action to protect passengers and aircrew from dangerous cabin fumes which they say have led to a new emerging disease. Led by former pilot and aviation health researcher, the specialists have released the first medical protocol of its kind to help treat those effected by contamination of the aircraft cabin breathing air supply and collect data on contamination events.

Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.

A detailed plan to transform product packaging and significantly cut plastic production and pollution has been developed by researchers. The study comes as government representatives meet in Paris to negotiate a legally binding global plastics treaty with a mandate to end plastic pollution.

The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is stored then used to dry foods or create electricity. A team has found that certain soapstone and granite samples from Tanzania are well suited for storing this solar heat, featuring high energy densities and stability even at high temperatures.

Exhaust fumes probably come to mind when considering vehicle emissions, but they aren't the only source of pollutants released by a daily commute. Researchers report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. Notably, the levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles.

A survey of philosophers finds they broadly agree with economists on the best way of valuing the environment of the future in policy decisions made now -- although for different reasons.

Researchers have published new findings on how our warming climate will affect the frequency of flash droughts and the risk to croplands globally.

Applying imaging technology to plant roots, researchers have developed a new understanding of chemicals that are responsible for plant growth. The chemical 'roadmap' identifies where key molecules are distributed along corn roots and how their placement factors into the plant's maturation.

A ground-breaking study has revealed that plants can efficiently remove toxic gasoline fumes, including cancer causing compounds such as benzene, from indoor air.

New research analyzes more than 25 years of climate and biological data. The findings include shorter hibernation periods in arctic ground squirrels, as well as differences between male and female hibernation periods.

The Midwestern United States has lost 57.6 billion tons of topsoil due to farming practices over the past 160 years, and the rate of erosion, even following the U.S. Department of Agriculture's guidelines, is still 25 times higher than the rate at which topsoil forms. Yet, we need not despair: researchers recently reported that no-till farming, which is currently practiced on 40 percent of cropland acres in the Midwest, can extend our current level of soil fertility for the next several centuries. This has implications for everything from food security to climate-change mitigation.

The effects of the ground on propeller noise have now been measured experimentally.

A team of engineers has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.

A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.

Scientists have found evidence that microplastics in the digestive tract of seabirds altered the microbiome of the gut -- increasing the presence of pathogens and antibiotic-resistant microbes, while decreasing the beneficial bacteria found in the intestines.

Seaside residents and holidaymakers have felt it for centuries, but scientists have only recently started to investigate possible health benefits of the coast. Using data from 15 countries, new research confirms public intuition: Living near, but especially visiting, the seaside is associated with better health regardless of country or personal income.

A new study has revealed that drying laundry using a condenser tumble dryer leads to hundreds of tons of potentially harmful microfibers being released into waterways and oceans across the UK and Europe.

A new study tracked the ability of natural, synthetic, and blended fabrics to biodegrade directly in the ocean.

Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
