Standard model of electroporation refuted      (via sciencedaily.com) 

Strong electric fields can be used to create pores in biomembranes. The method is known as electroporation. Inducing such defects in membranes in a targeted manner is an important technique in medicine and biotechnology, but also in the treatment of foodstuffs.

What 'Chornobyl dogs' can tell us about survival in contaminated environments      (via sciencedaily.com) 

In the first step toward understanding how dogs -- and perhaps humans -- might adapt to intense environmental pressures such as exposure to radiation, heavy metals, or toxic chemicals, researchers found that two groups of dogs living within the Chernobyl Exclusion Zone showed significant genetic differences between them. The results indicate that these are two distinct populations that rarely interbreed. While earlier studies focused on the effects of the Chernobyl Nuclear Power Plant disaster on various species of wildlife, this is the first investigation into the genetic structure of stray dogs living near the Chernobyl nuclear power plant.

Plant roots fuel tropical soil animal communities      (via sciencedaily.com) 

A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.

An internal thermometer tells the seeds when to germinate      (via sciencedaily.com) 

Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable. The survival of the young plant depends on the timing of this transition. It is therefore essential that this stage be finely controlled. Botanists have now discovered the internal thermometer of seeds that can delay or even block germination if temperatures are too high for the future seedling. This work could help optimize plant growth in a context of global warming.

Mineral particles and their role in oxygenating the Earth's atmosphere      (via sciencedaily.com) 

Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.

A mixture of trees purifies urban air best      (via sciencedaily.com) 

Conifers are generally better than broad-leafed trees at purifying air from pollutants. A new study shows that the best trees for air purification depend on the type of pollutant involved.

Rhythmic eating pattern preserves fruit fly muscle function under obese conditions      (via sciencedaily.com) 

Obese fruit flies are the experimental subjects in a study of the causes of muscle function decline due to obesity. In humans, skeletal muscle plays a crucial role in metabolism, and muscle dysfunction due to human obesity can lead to insulin resistance and reduced energy levels.

Biologists, chemical engineers collaborate to reveal complex cellular process inside petunias      (via sciencedaily.com) 

Once upon a time, prevailing scientific opinion might have pronounced recently published research as unneeded. Now, climate change implications have heightened the need for this line of research. Flowers emit scent chemicals called volatile organic compounds (VOCs). Earlier this year, a study identified a protein that plays a key role in helping petunias emit volatiles.

Earlier take-off could lead to fewer bumblebees and less pollination      (via sciencedaily.com) 

With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.
