Scientists discover natural fitness watch in fishes that records their activity levels

Scientists have shown for the first time that the energetic cost of living (the metabolic rate) of fish can be measured in structures that grow in their ears. This new tool can be used to show how fish are influenced by and adapt to changes in their environment, including climate change.

Air pollution increases ER visits for breathing problems

As levels of ozone and fine particulate pollution (PM2.5) rise, more patients end up in the ER with breathing problems, according to the largest US study of air pollution and respiratory emergency room visits of patients of all ages.

Fighting deadly drug resistant bacteria in intestines with new antibiotic

Clostridium difficile infection (CDI) is a potentially deadly infection in the large intestine most common in people who need to take antibiotics for a long period of time, particularly in Australia's ageing population. But when doses of a new antibiotic called Ramizol were given to hamsters infected with a lethal dose of the bacteria, a significant proportion of hamsters survived the infection.

Killer blows? Knockout study of pair of mouse MicroRNA provides cancer insight

Researchers used knockout mouse models created by gene editing to reveal that the miRNA miR-146b, like miR-146a, is involved in the development of cancers, with them having similar but not identical effects. The knockout mice should help in the fight against cancers involving miRNA dysregulation.

Mangrove patches deserve greater recognition no matter the size

Governments must provide stronger protection for crucial small mangrove patches, experts say.

New ways to harness wasted methane

The primary component of natural gas, methane, is itself a potent greenhouse gas. A recent study has unveiled a high performance catalyst for methane conversion to formaldehyde.

Mediterranean freshwater fish species susceptible to climate change

Climate change will strongly affect many European freshwater fish species. This is particularly the case for species in the Mediterranean region.

Orchards in natural habitats draw bee diversity, improve apple production

Apple orchards surrounded by agricultural lands are visited by a less diverse collection of bee species than orchards surrounded by natural habitats.

Artificially produced cells communicate with each other

Researchers have for the first time created artificial cell assemblies that can communicate with each other. The cells, separated by fatty membranes, exchange small chemical signaling molecules to trigger more complex reactions, such as the production of RNA and other proteins.

Gene therapy blocks peripheral nerve damage in mice

Scientists have developed a gene therapy that blocks axonal degeneration, preventing axon destruction in mice and suggesting a therapeutic strategy that could help prevent the loss of peripheral nerves in multiple conditions.
