Protected nature reserves alone are insufficient for reversing biodiversity loss      (via sciencedaily.com)     Original source 

Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.

Some spiders can transfer mercury contamination to land animals      (via sciencedaily.com) 

Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.

Hot summer air turns into drinking water with new gel device      (via sciencedaily.com) 

Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.

Atmospheric scientists reveal much of Houston's ozone exceedance due to air flows from the north      (via sciencedaily.com)     Original source 

Atmospheric science researchers published findings on Houston's ozone. They found that while local emissions play a role in the rise of Houston's ozone levels, most of the pollutants are carried in from other parts of the country.

You say tomato, these scientists say evolutionary mystery      (via sciencedaily.com)     Original source 

Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.

Urban parks built on former waste incineration sites could be lead hotspots      (via sciencedaily.com) 

A new study finds that surface soil in parks and playgrounds built on former waste incineration and ash disposal sites may contain levels of lead exceeding EPA safety standards for areas where children play. The contamination, which can persist long after an incinerator is closed, stems from burning paint, pipes and other products that contained lead. Sites in hundreds of U.S. and Canadian cities could be contaminated. Increased monitoring is needed to pinpoint hotspots.

Scientific ocean drilling discovers dynamic carbon cycling in the ultra-deep-water Japan Trench      (via sciencedaily.com)     Original source 

Hadal trenches, with their deepest locations situated in the so-called hadal zone, the deepest parts of the ocean in water depth >6km, are the least-explored environment on Earth, linking the Earth's surface and its deeper interior. An international team conducting deep-subsurface sampling in a hadal trench at high spatial resolution has revealed exciting insights on the carbon cycling in the trench sediment.

Hybrid catalyst produces critical fertilizer and cleans wastewater      (via sciencedaily.com)     Original source 

Synthetically produced fertilizer urea supports half of global population. Using pure metals, researchers develop hybrid catalyst with capacity to convert waste nitrogen and carbon dioxide to urea. The process could denitrify wastewater and runoff while creating a new revenue stream for water treatment facilities.

'A crab is never just a crab'      (via sciencedaily.com)     Original source 

A herring in the North Sea, a crab in the Wadden Sea or an anemone fish on a coral reef, ... biologists like to think in terms of individual species that all have their own place within food webs in ecosystems across the world. 'But that is surely too simplistic thinking,' researchers warn.
