Making hydrogenation greener

Researchers from McGill University, RIKEN (The Institute of Physical and Chemical Research, Wako, Japan) and the Institute for Molecular Science (Okazaki, Japan) have discovered a way to make the widely used chemical process of hydrogenation more environmentally friendly – and less expensive.

Dynamic interplay of ecology, infectious disease, and human life

Two symposia focusing on the ecological dynamics of infectious diseases such as avian influenza, Yellow Fever, and Lyme will take place during the Ecological Society of America's 98th Annual Meeting, held this year in Minneapolis, Minnesota. One will look at human influences on viral and bacterial diseases through our alteration of landscapes and ecological processes, while the other will focus on the emerging field of eco-epidemiology that seeks to integrate biomedical and ecological research approaches to address human health threats.

Sea lampreys turning up the heat

Male sea lampreys may not be the best-looking creatures swimming in our lakes and streams, but they apparently have something going for them that the ladies may find irresistible.

Research by a team of Michigan State University scientists found that the males have a secondary sex characteristic that creates heat when they get near a female lamprey, something the females find hard to say no to.

Pneumonia revealed in a cough

A new method, which analyzes the sounds in a child's cough, could soon be used in poor, remote regions to diagnose childhood pneumonia reliably. According to Udantha Abeyratne from the University of Queensland in Australia and colleagues, this simple technique of recording coughs with a microphone on the patient's bedside table, has the potential to revolutionize the management of childhood pneumonia in remote regions around the world. Their work¹ is published online in Springer's journal Annals of Biomedical Engineering².

Beautiful but hiding unpleasant surprise: 3 new species of fetid fungi from New Zealand

With the help of phylogenetic analysis, scientists describe three new fungus species from New Zealand. The new species belong to the widespread genus Gymnopus, part of the Omphalotaceae family, the most famous representative of which, the Shiitake mushroom, is the favorite of many. The study was published in the open access journal Mycokeys.

Some like it hot: The role of heat in sea lampreys' sex lives

'Is it hot in here or is it just you?' Clichéd chat-up lines may serve some humans well, but other animals prefer more imaginative ways to captivate and attract potential suitors. Take, for example, the male sea lamprey, which will coax ovulating females into its nest by releasing enticing pheromones. Once comfortably in the nest, the male will then perform an interesting dance routine, rubbing the female's belly with a small bump of tissue on his back. Should the female be happy with what she sees and feels, the two will then spawn their gametes simultaneously.

Insulin differs between ethnicities, study finds

People have differing abilities to release and react to insulin depending on ethnicity, according to a new study from researchers at Lund University in Sweden, Stanford University and Kitasato University.

The results show that healthy subjects of all ethnicities were able to maintain a normal glucose level, but did so in different ways.

Polymer coatings a key step toward oral delivery of protein-based drugs

PROVIDENCE, R.I. [Brown University] — For protein-based drugs such as insulin to be taken orally rather than injected, bioengineers need to find a way to shuttle them safely through the stomach to the small intestine where they can be absorbed and distributed by the bloodstream.

A new bizarrely shaped spoon worm, Arhynchite hayaoi, from Japan

A new species of the peculiarly shaped spoon worms has been recently discovered in Japan, and described in the open access journal Zookeys. These animals derive their name from their elongated and spoon-like projection (the proboscis), issuing from the barrel- or sweet potato-like roundish body proper (the trunk).

Bioeconomy as a solution for South Australia's declining forest industry

South Australia's forest industry is being significantly challenged as production levels fall due to declining export competitiveness and accordingly means for improving the industry's competitiveness are being sought. The South Australian State Government's Department for Manufacturing, Innovation, Trade, Resources and Energy (DMITRE) has invited VTT Technical Research Centre of Finland experts to undertake a study that identifies potential routes by which the increased competitiveness can be achieved.

New red blood simulator invented at Queen Mary

Engineers from Queen Mary, University of London have developed the world's most precise computer simulation of how red blood cells might travel around the body to help doctors treat people with serious circulatory problems.

Red blood cells have the important task of carrying oxygen around the body but make up less than half of the total blood volume – 45 per cent in men and 40 per cent in women.

Chapman University unearths data in animal habitat selection that counters current convention

ORANGE, Calif. – Chapman University's Walter Piper, Ph.D., has published research this week in a leading science journal that shows animals choose habitat similar to where they were raised rather than that likely to maximize reproductive success. This finding runs counter to current tenets of habitat selection theory.

The paper is published in the Proceedings of the Royal Society B on June 26 and includes co-authors Michael Palmer, Nathan Banfield and Michael Meyer. Dr. Piper's research focuses on his long-term study of loons.

Spinning up antibacterial silver on glass

The antibacterial effects of silver are well established. Now, researchers at Yonsei University in Seoul, Republic of Korea, have developed a technique to coat glass with a layer of silver ions that can prevent growth of pathogenic bacteria including Escherichia coli, Salmonella typhimurium and Campylobacter jejuni. The technology could be used to protect medical equipment and be particularly useful for applications in disaster recovery and the military environment.

Link shown between Crohn's disease and virus

A new study reveals that all children with Crohn's disease that were examined had a commonly occurring virus – an enterovirus – in their intestines. This link has previously not been shown for this chronic inflammatory intestinal disorder. The findings are being published today in the latest issue of the international journal Clinical and Translational Gastroenterology.

Researchers discover human activity threatens Sumatran tiger population

Sumatran tigers, found exclusively on the Indonesian island of Sumatra, are on the brink of extinction. By optimistic estimates, perhaps 400 individuals survive. But the exact the number and locations of the island's dwindling tiger population has been up for debate.
