More research called for into HIV and schistosomiasis coinfection in African children

Researchers from LSTM have called for more research to be carried out into HIV and schistosomiasis coinfection in children in sub-Saharan Africa.

Biomedical applications of shape-memory polymers: How practically useful are they?

Polymers that exhibit shape-memory effect (SME) are an important class of materials in medicine, especially for minimally invasive deployment of devices. Professor Subbu Venkatraman and his group from School of Materials Science and Engineering, Nanyang Technological University presented a review article surveying the clinical applications of the SME and addressing critically the question of its utility in implantable devices.

More effective kidney stone treatment, from the macroscopic to the nanoscale

Researchers in France have hit on a novel method to help kidney stone sufferers ensure they receive the correct and most effective treatment possible.

Kidney stones represent a major medical problem in the western and developing world. If left untreated, apart from being particularly painful, they can lead to renal failure and other complications. In many patients treated successfully, stone recurrence is also amajor problem. Clearly a more effective pathological approach to diagnosis and treatment needs to be identified to ensure successful eradication of stones.

Chiral breathing: Electrically controlled polymer changes its optical properties

Electrically controlled glasses with continuously adjustable transparency, new polarisation filters, and even chemosensors capable of detecting single molecules of specific chemicals could be fabricated thanks to a new polymer unprecedentedly combining optical and electrical properties.

In sex-reversed cave insects, females have the penises

Researchers reporting in the Cell Press journal Current Biology on April 17 have discovered little-known cave insects with rather novel sex lives. The Brazilian insects, which represent four distinct but related species in the genus Neotrogla, are the first example of an animal with sex-reversed genitalia.

"Although sex-role reversal has been identified in several different animals, Neotrogla is the only example in which the intromittent organ is also reversed," says Kazunori Yoshizawa from Hokkaido University in Japan.

Some immune cells defend only 1 organ

Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness.

The research, in mice, suggests that some organs have the immunological equivalent of "neighborhood police" – specialized squads of defenders that patrol only one area, a single organ, instead of an entire city, the body.

Deaths from viral hepatitis surpasses HIV/AIDS as preventable cause of deaths in Australia

The analysis was conducted by Dr Benjamin Cowie and Ms Jennifer MacLachlan from the University of Melbourne and Melbourne Health, and was presented at The International Liver Congress in London earlier this month.

"Liver cancer is the fastest increasing cause of cancer deaths in Australia, increasing each year by 5 per cent, so by more than seventy people each year. In 2014 there was an estimated number of deaths of around 1,500 from liver cancer. The predominant cause is chronic viral Hepatitis," Dr Cowie said.

Scientists find new way to fight malaria drug resistance

An anti-malarial treatment that lost its status as the leading weapon against the deadly disease could be given a new lease of life, with new research indicating it simply needs to be administered differently.

The findings could revive the use of the cheap anti-malarial drug chloroquine in treating and preventing the mosquito-bourne disease, which claims the lives of more than half a million people each year around the world.

Rapid and accurate mRNA detection in plant tissues

Gene expression is the process whereby the genetic information of DNA is used to manufacture functional products, such as proteins, which have numerous different functions in living organisms. Messenger RNA (mRNA) serves as an important intermediary during gene expression, by relating the genetic information of DNA to the molecular mechanisms involved in manufacturing proteins.

Radiation therapy for cervical cancer increases risk for colorectal cancer

Researchers at the University of Texas Medical Branch at Galveston are the first to recommend that young women treated with radiation for cervical cancer should begin colorectal cancer screening earlier than traditionally recommended.

Stanford biologists help solve fungal mysteries

Pine forests are chock full of wild animals and plant life, but there's an invisible machine underground. Huge populations of fungi are churning away in the soil, decomposing organic matter and releasing carbon into the atmosphere.

Despite the vital role these fungi play in ecological systems, their identities have only now been revealed. A Stanford-led team of scientists has generated a genetic map of more than 10,000 species of fungi across North America. The work was published this week in the Proceedings of the National Academy of Sciences.

Genetic study tackles mystery of slow plant domestications

"The Modern View of Domestication," a special feature of The Proceedings of the National Academy of Sciences (PNAS) published April 29, raises a number of startling questions about a transition in our deep history that most of us take for granted. At the end of the last Ice Age, people in many spots around the globe shifted from hunting animals and gathering fruits and tubers to cultivating livestock and plants.

The story of animal domestication retold

Many of our ideas about domestication derive from Charles Darwin, whose ideas in turn were strongly influenced by British animal-breeding practices during the 19th century, a period when landowners vigorously pursued systematic livestock improvement.

It is from Darwin that we inherit the ideas that domestication involved isolation of captive animals from wild species and total human control over breeding and animal care.

Creative activities outside work can improve job performance

SAN FRANCISCO -- Employees who pursue creative activities outside of work may find that these activities boost their performance on the job, according to a new study by San Francisco State University organizational psychologist Kevin Eschleman and colleagues.

Creative pursuits away from work seem to have a direct effect on factors such as creative problem solving and helping others while on the job, said Eschleman, an assistant professor of psychology.

Research shows that bacteria survive longer in contact lens cleaning solution than thought

Each year in the UK, bacterial infections cause around 6,000 cases of a severe eye condition known as microbial keratitis – an inflammation and ulceration of the cornea that can lead to loss of vision. The use of contact lenses has been identified as a particular risk factor for microbial keratitis. New research, presented today at the Society for General Microbiology Annual Conference in Liverpool, shows that a bacterial strain associated with more severe infections shows enhanced resistance to a common contact lens disinfectant solution.
