An infection with Chagas disease is only possible in Latin America since the insect species that spread the disease only occur there. Scientists at Goethe University and the Senckenberg Society for Natural Research have now used ecological niche models to calculate the extent to which habitats outside of the Americas may also be suitable for the bugs. The result: climatically suitable conditions can be found in southern Europe for two kissing bug species; along the coasts of Africa and Southeast Asia the conditions are suitable for yet another species.
All human body cells have a certain lifespan, during which they perform their essential duties. At the end of this lifespan, they reach senescence and-no longer able to perform those duties-die. This suicidal death is programmed into their genes through a process called apoptosis, causing them to self-destruct in order to make way for fresh, young, and healthy cells to replace them.
Around 194 million birds and 29 million mammals are thought to be killed each year on European roads, according to a new study that has ranked the most vulnerable species.
An international research team used 90 roadkill surveys from 24 European countries to create a new method of estimating both the birds and mammal species killed most often on roads, and the species most vulnerable to being wiped out of certain areas.
Researchers at the University of British Columbia (UBC) and Vancouver Coastal Health Research Institute (VCHRI) have identified a key enzyme that contributes to eczema, which may lead to better treatment to prevent the skin disorder's debilitating effects.
The study was recently published in the Journal of Investigative Dermatology.
First impressions can have long-term effects on people's perceptions and behavior. A new study looked at the influence among finance professionals of first impression bias of firms' performance, which spurs people to place undue weight on early experiences. The study found that equity analysts placed greater emphasis on early impressions than later ones, that negative first impressions had more power than positive ones, and that first impression bias could influence forecasts of a firm by a financial professional for up to six years.
DALLAS, June 10, 2020 -- Current cigarette smoking and the number of cigarettes smoked per day are associated with more than twice the risk for all stroke - ischemic and hemorrhagic - among African Americans compared to nonsmokers, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.
Space weather forecasters need to predict the speed of solar eruptions, as much as their size, to protect satellites and the health of astronauts, scientists have found.
BATON ROUGE, Louisiana - A new study offers the first evidence that a chemical compound named BAM15 acts as an energy uncoupler and could be an effective drug for treating obesity and related diseases.
Obesity affects more than 650 million people worldwide and drives a number of dangerous health conditions, including type 2 diabetes, heart disease and more than a dozen deadly cancers. Global spending to treat obesity and obesity-related illnesses amounts to well above $150 billion a year.
Washington, DC (June 8, 2020) - A new study from Boston University published on-line at BMC Nutrition by Lynn L. Moore and colleagues, found that drinking 100% fruit juice early in life was associated with healthier dietary patterns in later childhood without adversely impacting weight gain. The study found that consumption of 100% fruit juice during the preschool years was associated with higher intakes of whole fruit and total fruit as well as better diet quality through childhood and into middle adolescence.
The physical and chemical properties of intermetallic compounds are governed by the real structure of synthesized materials and are strongly influenced by the structural imperfections, e.g. strain, dislocations, and presence of admixture phases. This leads to inconsistent reports for known and extensively studied materials. Among such compounds is TaGeIr, which crystallizes with the MgAgAs type of structure.
A new study shows invasive native species of rushes are spreading across UK upland farms and have the potential to threaten wildlife and the livelihoods of farmers.
Scientists have used a series of Google Earth images to plot the spread of rushes in farm fields in the West Pennine Moor SSSI - an area of the Lancashire uplands between Bolton, Bury and Darwen.
The search for renewable energy sources, which include wind, solar, hydroelectric dams, geothermal, and biomass, has preoccupied scientists and policymakers alike, due to their enormous potential in the fight against climate change. A new Tel Aviv University study finds that water vapor in the atmosphere may serve as a potential renewable energy source in the future.
Once a tropical storm in the Gulf of Mexico, now a tropical depression in the Mississippi Valley, NASA's Aqua satellite is tracking Cristobal as it continues to generate large amounts of rainfall while it heads toward the Great Lakes region.

LONDON, ON - A new study from Lawson Health Research Institute and Western University suggests that fecal transplants could be used as a treatment for non-alcoholic fatty liver disease (NAFLD). The randomized controlled trial published in the American Journal of Gastroenterology found that fecal transplants in patients with NAFLD result in a reduction in how easily pathogens and other unwanted molecules pass through the human gut and into circulation, known as intestinal permeability.
The family Elmidae (riffle beetles) is well studied and the existence of 17 genera with 57 species have been reported in Japan so far.
