The new frontier in plasma medicine

Applications of plasmas in medicine are a new frontier in therapeutic treatment. For example, they can help in stimulating tissue regeneration in the contexts of wound healing and dermatology. Before these and further applications can be developed, it is essential to understand the processes at work in plasmas - a unique kind of gas-like state of matter containing charged particles. Now a study published in EPJ D by a team led by Zoran Petrovi? from the University of Belgrade, Serbia, provides previously unavailable data on oxygen ion transport and the likelihood of such ions interacting with water molecules. These could contribute to new models of plasmas in liquids which account for how discharges are created in water vapour.

Earth news

Scientists find tropical cyclone size controlled by relative sea-surface temperatures

A team of scientists including Minghua Zhang, Dean and Director of Stony Brook University School of Marine and Atmospheric Sciences (SoMAS), have found that the size of tropical cyclones is controlled by their underlying sea-surface temperatures (SST) relative to the conditions of the mean SST within the surrounding tropical zone of the storms. Their findings, published early online in Nature Communications, imply that under a warmer climate, the size of tropical cyclones (including hurricanes), are not based on the absolute value of SST alone.

Cascades study may rewrite the textbook on forest growth and death

A century-long study in the Oregon Cascades may cause scientists to revise the textbook on how forests grow and die, accumulate biomass and store carbon.

Amazon's carbon uptake declines as trees die faster

The most extensive land-based study of the Amazon to date reveals it is losing its capacity to absorb carbon from the atmosphere. From a peak of two billion tonnes of carbon dioxide each year in the 1990s, the net uptake by the forest has halved and is now for the first time being overtaken by fossil fuel emissions in Latin America.

Computer sims: In climatic tug of war, carbon released from thawing permafrost wins handily

There's a carbon showdown brewing in the Arctic as Earth's climate changes. On one side, thawing permafrost could release enormous amounts of long-frozen carbon into the atmosphere. On the opposing side, as high-latitude regions warm, plants will grow more quickly, which means they'll take in more carbon from the atmosphere.

Strong undersea earthquake hits eastern Indonesia

Deep-sea robot, caught in underwater avalanche, yields new scientific insights

Exploring the deep sea, and especially submarine canyons, is a risky business. The floors of many submarine canyons are periodically scoured by fast-moving underwater avalanches known as "turbidity currents." In 2013, one of MBARI's remotely operated vehicles (ROVs) was literally swept away by a turbidity current. Fortunately, the vehicle survived, giving researchers their first close-up view of one of these enigmatic events. The resulting video and data suggest that conceptual models and even textbook descriptions of turbidity currents may need to be revised.

Submarine groundwater discharge adds as much nutrients as rivers to the Mediterranean Sea

Submarine groundwater discharge (SGD) consists of a mixture of continental freshwater and seawater, which recirculates through the coastal aquifer. In addition to its importance in the water cycle, as a potentially exploitable water resource and a source of water for brackish coastal environments such as marshes and coastal lagoons, it also can serve as an important source of dissolved chemical compounds such as nutrients and trace and toxic metals.

A single-cell breakthrough

The human gut is a remarkable thing. Every week the intestines regenerate a new lining, sloughing off the equivalent surface area of a studio apartment and refurbishing it with new cells. For decades, researchers have known that the party responsible for this extreme makeover were intestinal stem cells, but it wasn't until this year that Scott Magness, PhD, associate professor of medicine, cell biology and physiology, and biomedical engineering, figured out a way to isolate and grow thousands of these elusive cells in the laboratory at one time. This high throughput technological advance now promises to give scientists the ability to study stem cell biology and explore the origins of inflammatory bowel disease, intestinal cancers, and other gastrointestinal disorders.

Anthropologists study hormonal basis of affiliation and competition among hunters in Bolivian Amazon

Absence, it seems, really does make the heart grow fonder. That's according to research conducted by UC Santa Barbara anthropologists, who found that levels of the "love" hormone oxytocin increases among Tsimane men when they come home to their families after a day of hunting. The researchers also found that the increase in oxytocin was greater for those men who were absent longer, and it positively correlated with changes in testosterone. Their findings are published in the Royal Society journal Biology Letters.

Light pollution influences the seasonal start of bird vocalisations

Under the influence of artificial night lighting, four out of six studied songbird species started dawn and dusk singing earlier in the year. This was shown by scientists of the Max Planck Institute for Ornithology when they studied bird vocalizations from winter to spring in dark sites and in sites exposed to light pollution. An earlier seasonal start of dawn and dusk singing was particularly noticeable in the early risers among the species, suggesting that they are influenced the most by artificial night lighting. Whether the observed effects have consequences for the fitness of the animals remains unknown and needs further investigation.

Evolution of the back-to-belly axis

Most animals have a dorso-ventral (back-to-belly) body axis, which determines for instance the localized position of the central nervous system, dorsal in humans, ventral in insects. Surprisingly, despite enormous morphological differences, the same signaling molecules of Bone morphogenetic protein (BMP) molecules establishes the dorso-ventral axis including the central nervous system in both insects and vertebrates, which led to the conclusion that this molecular mechanism was already present in the common ancestor.

Passive acoustic monitoring method for the detection of chimpanzees and two monkey species

Traditionally, censusing of wild primates has been conducted using transect methodology where teams of human surveyors walk kilometers of line transects to collect data on primate sightings and vocalizations. Motivated by the increasing availability of cost-efficient audio-visual technologies, researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, investigated to what extent autonomous recording devices, combined with an automated data processing approach, could be used to monitor wild forest primates. To achieve this goal they used an interdisciplinary team of sound engineers, biomonitoring specialists, statisticians, and primate vocalization experts.

Leaf odor attracts Drosophila suzukii

In 2014, more spotted-wing Drosophila suzukii than ever before were observed in Germany. This pest lays its eggs in fresh and ripening fruits before they are harvested. Infested fruits are often additionally infected with bacteria and fungi, and become unsuitable for sale and further processing. Currently, the only way to effectively control this pest insect is through the use of insecticides. Scientists at the Max Planck Institute for Chemical Ecology have now identified a leaf odor which is highly attractive to Drosophila suzukii. Beta-cyclocitral lures the spotted-wing drosophila but no other related drosophilids. Researchers were able to measure the olfactory specialization of the insect to this leaf odor on the basis of the response of a certain sensillum.

Male fish dig pits and build sand castles at the bottom of Lake Malawi to attract females

New research shows that courtship rituals evolve very fast in cichlid fish in Lake Malawi. Whenever species evolve to feed at different depths, their courtship evolves as well. In the shallows where the light is good, males build sand castles to attract females. Males of deep-dwelling species dig less elaborate pits and compensate with longer swimming displays. The results are published in the open-access journal Frontiers in Ecology and Evolution.

Pesticides not the sole culprit in honey bee colony declines

Colony declines are a major threat to the world's honey bees, as well as the many wild plants and crops the bees pollinate. Among the lineup of possible culprits—including parasites, disease, climate stress and malnutrition—many have pointed the finger squarely at insecticides as a prime suspect. However, a new study from the University of Maryland shows that the world's most common insecticide does not significantly harm honey bee colonies at real-world dosage levels.

Rodents infected with a common parasite lose their fear of cats, resulting in easy meals for the felines. Now IU School of Medicine researchers have identified a new way the parasite may modify brain cells, possibly helping explain changes in the behavior of mice—and humans.

Study claims forensic examiners—and not plant ecologists—first to recognize 'ecological succession'

For generations, students have been taught the concept of "ecological succession" with examples from the plant world, such as the progression over time of plant species that establish and grow following a forest fire. Indeed, succession is arguably plant ecology's most enduring scientific contribution, and its origins with early 20th-century plant ecologists have been uncontested. Yet, this common narrative may actually be false. As posited in an article published in the March 2015 issue of The Quarterly Review of Biology, two decades before plant scientists explored the concept, it was forensic examiners who discovered ecological succession.

Nearly 150 trafficked animals flown to Amazon freedom

Native fish species under pressure in the Engadine and Poschiavo

From 2010 to 2014, a total of 26 prealpine lakes were studied as part of Projet Lac, with over 60 fish species being recorded. In 2012, in cooperation with Canton Graubünden's Hunting and Fishery Office, surveys were carried out on Lake Sils in the Engadine and Lago di Poschiavo. The results, now available, show that both of these lakes harbour a commercially attractive salmonid community. However, both lakes' historical diversity has been significantly affected by the introduction of fish species from several other catchments – in particular, the Arctic char (Salvelinus alpinus), Canadian lake trout (Salvelinus namaycush) and brown trout (Salmo trutta). Genetic analyses indicate that the non‑native fish have interbred with indigenous species, leading to substantial losses of biodiversity. The distinctiveness of the original Lake Poschiavo trout, for example, has largely been lost. In Lake Sils, however, an indigenous populat! ion of Black Sea trout (Salmo labrax) seems to have survived despite stocking with brown trout.

Changes in health care delivery essential to combat chronic disease

Chronic disease accounts for 7 of every 10 deaths in the United States and more than 75% of total health care costs. Among people 65 years old and older, over 92% suffer from one or more chronic diseases. By 2020, it is estimated that 48% of the total population will have chronic disease. In an article published in The American Journal of Medicine, researchers discuss how existing health care delivery models are poorly constructed to manage chronic disease, and how a reengineering of the health care system might offer some hope in meeting this challenge.

Fatal uncoupling in the epileptic brain

Epilepsy is a very prevalent neurological disorder. Approximately one-third of patients are resistant to currently available therapies. A team of researchers under the guidance of the Institute of Cellular Neurosciences at the University of Bonn has discovered a new cause to explain the development of temporal lobe epilepsy: At an early stage, astrocytes are uncoupled from each other. This results in the extracellular accumulation of potassium ions and neurotransmitters, which cause hyperexcitability of the neurons. The results are being published in advance online in the journal Brain. The print version will be published in May.

Protein sequencing solves Darwinian mystery of 'strange' South American mammals

Scientists have resolved pieces of a nearly 200-year-old evolutionary puzzle surrounding the group of mammals that Charles Darwin called the "strangest animals ever discovered." New research led by the American Museum of Natural History, the Natural History Museum in London, and the University of York shows that South America's so-called "native ungulates"—the last of which disappeared only 10,000 years ago—are actually related to mammals like horses rather than elephants and other species with ancient evolutionary ties to Africa as some taxonomists have maintained. Published today in the journal Nature, the findings are based on fossil protein sequences, which allow researchers to peek back in time up to 10 times farther than they can with DNA.

Out-of-wedlock childbearing increasingly common among educated women in Latin America

"Consensual unions," two people living in the same dwelling in a relationship akin to marriage, have been an integral part of family life in Latin America for centuries. In fact, in Latin America, legal marriages and consensual unions are seen as similarly acceptable family arrangements for bearing and raising children. However, consensual unions have historically been more common among disadvantaged populations and in rural areas than among more advantaged populations and in urban areas—indicating that such unions are rooted in limited economic and social opportunities. But a study in the March 2015 issue of Population and Development Review finds that childbearing within a consensual union among highly educated women has transitioned from rare to increasingly common in 13 Latin American countries.
