Researchers discover tissue-specific protection against protein aggregation      (via sciencedaily.com)     Original source 

Researchers have identified a backup mechanism of protein quality control which prevents the toxic effects of protein aggregation in specific tissues when normal methods of molecular monitoring fail. By understanding how different tissues tackle protein build up, this research could accelerate the identification of ways to protect tissues that are vulnerable to protein build up, possibly tackling both disease-associated protein aggregates and also age-dependent aggregates that accelerate the functional decline of tissues.

Mysterious family of microbial proteins hijack crops' cellular plumbing      (via sciencedaily.com)     Original source 

Some crop pathogens use a clever trick to multiply and spread infection: they hijack the plant's cellular plumbing. In a new study, researchers unveil a class of bacterial proteins that fold into a straw-like shape and insert themselves into the plant cell membrane, allowing the inside of the leaf to become waterlogged. The researchers also figured out a possible way to block the water channel proteins and prevent infection.

Scientists find good places to grow long-spined sea urchins, a starting point to restore 'the lawn mowers of the reefs'      (via sciencedaily.com) 

Scientists are trying to raise as many urchins as possible because they eat algae that could otherwise smother reef ecosystems and kill corals. Researchers have identified algae on which larval sea urchins grow into juveniles in a lab setting.

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.

'Dormant' HIV produces RNA and proteins during anti-retroviral therapy      (via sciencedaily.com)     Original source 

HIV anti-retroviral therapy is considered a treatment and not a cure because patients usually carry a reservoir of HIV-infected cells that can re-emerge if treatment stops. These reservoirs have long been thought to be dormant, but two independent groups of researchers report that a subset of these cells spontaneously produce HIV RNA and proteins that may impact patients' HIV-specific immune responses.

Freshwater connectivity can transport environmental DNA through the landscape      (via sciencedaily.com) 

A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.

'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.

Nutrients drive cellular reprogramming in the intestine      (via sciencedaily.com)     Original source 

Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth. The study, which was conducted on fruit flies (Drosophila), provides further insights into dedifferentiation -- where specialized cells that have specific functions transform into less specialized, undifferentiated cells like stem cells.
