Human disease leptospirosis identified in new species, the banded mongoose, in Africa

The newest public health threat in Africa, scientists have found, is coming from a previously unknown source: the banded mongoose.

Leptospirosis, the disease is called. And the banded mongoose carries it.

Leptospirosis is the world's most common illness transmitted to humans by animals. It's a two-phase disease that begins with flu-like symptoms. If untreated, it can cause meningitis, liver damage, pulmonary hemorrhage, renal failure and death.

Illusion of control: Why sports fans prefer 'lucky' products

Consumers engage in superstitious behavior when they want to achieve something but don't have the power to make it happen, according to a new study in the Journal of Consumer Research.

"Preference for lucky products (those associated with positive outcomes) increases when a strong desire for control is combined with lower perceived ability to exert control. Consumers who make superstitious choices believe they will be effective in helping them achieve the desired outcome," write authors Eric J. Hamerman (Tulane University) and Gita V. Johar (Columbia University).

Learning to recycle: Does political ideology matter?

Some targeted messages based on political orientation are more effective at persuading consumers to recycle, according to a new study in the Journal of Consumer Research.

Multilingual survey research: Do poor translations cause bias?

Survey results may be biased in multilingual research if consumers are unfamiliar with translated terms, according to a new study in the Journal of Consumer Research.

Primary care physicians vital to complete care of prostate cancer patients

Androgen deprivation therapy is a common and effective treatment for advanced prostate cancer. However, among other side-effects, it can cause significant bone thinning in men on long-term treatment. A new study¹ by Vahakn Shahinian and Yong-Fang Kuo from the Universities of Michigan and Texas respectively, finds that although bone mineral density testing is carried out on some men receiving this therapy, it is not routine. They did note, however, that men were significantly more likely to be tested when they were being cared for by both a urologist and a primary care physician.

When green means danger: A stunning new species of palm-pitviper from Honduras

A new species of green palm-pitviper of the genus Bothriechis is described from a seriously threatened cloud forest reserve in northern Honduras. Because of similarity in color pattern and scalation, the new species (Bothriechis guifarroi) was previously confused with other Honduran palm pitvipers. Genetic analysis revealed that the closest relatives of the new species are actually found over 600 km to the south, in the mountains of Costa Rica.

Bacterium counteracts 'coffee ring effect'

Ever notice how a dried coffee stain has a thicker outer rim, while the middle of the stain remains almost unsoiled? This 'coffee ring effect' also occurs in other materials. Researchers from the Departments of Chemical Engineering and Chemistry at KU Leuven have now discovered how to counteract coffee rings with 'surfactants', i.e. soap. The key to the discovery was not a kitchen towel, but a bacterium that counteracts the coffee ring effect at the microscopic level. The findings were published in a recent edition of the leading journal Nature Communications.

Cutting-edge bacteria research leads to more effective treatment of complex infections

Bacteria are life forms, which, like all other life forms, struggle for the best living conditions for themselves. Therefore they will try to avoid getting attacked by the human immune system, and therefore they have developed various ways to protect themselves from the human immune system. When safe from the immune system, they can focus on breeding and multiplying, and if they become numerous enough, the human body will experience their presence as an infection. Some bacteria are relatively harmless, while others are fatal.

Widespread but neglected disease a health threat in Africa, Virginia Tech researchers say

The newest public health threat in developing countries may not be a cinematic-quality emerging disease but actually a disease from animals that was identified more than 100 years ago.

Advertising product results? Put images closer together

Consumers believe a product is more effective when images of the product and its desired outcome are placed closer together in advertisements, according to a new study in the Journal of Consumer Research.

Cell and environment: But what does it do?

Although we know the tool's general purpose, it can sometimes be difficult to tell if a specific pair of precision tweezers belongs to a surgeon or a master jeweler. It is now easier to solve similar conundrums about a type of protein that allows cells to react to their environment, thanks to scientists at the European Molecular Biology Laboratory (EMBL).

Do potatoes grow on vines? A review of the wild relatives of some favorite food plants

The Solanaceae, also called the potato or nightshade family, includes a wide range of flowering plants, some of which are important agricultural crops. Tomatoes, potatoes, aubergines, peppers and wolfberries are all representatives of the family present on many tables across the world. Solanum is the largest genus of the family, and with 1500 species, is one of the largest genera of flowering plants. Solanum has 13 major evolutionary groups,or clades.

From ocean to land: The fishy origins of our hips

New research has revealed that the evolution of the complex, weight-bearing hips of walking animals from the basic hips of fish was a much simpler process than previously thought.

Tetrapods, or four-legged animals, first stepped onto land about 395 million years ago. This significant change was made possible by strong hipbones and a connection through the spine via an ilium - features that were not present in the fish ancestors of tetrapods.

Flower power fights orchard pests

WENATCHEE, Wash. – Washington State University researchers have found they can control one of fruit growers' more severe pests, aphids, with a remarkably benign tool: flowers. The discovery is a boon for organic as well as conventional tree fruit growers.

The researchers recently published their study in the journal Biological Control. They found that plantings of sweet alyssum attracted a host of spiders and predator bugs that in turn preyed on woolly apple aphids, a pest that growers often control with chemical sprays.

Alligator stem cell study gives clues to tooth regeneration

Alligators may help scientists learn how to stimulate tooth regeneration in people, according to new research led by the Keck School of Medicine of the University of Southern California (USC).
