A team of researchers from Simon Fraser University and Culex Environmental, a Burnaby-based mosquito control company, are studying an invasive, disease-carrying mosquito, Aedes japonicus, after finding it for the first time in Western Canada. Their research has been published in the Journal of Medical Entomology.

Non-white race and lack of education are known risk factors for pain and poorer function after knee replacement surgery. What isn't clear is how a community's poverty level affects the outcomes of having a joint replaced. Findings from a new study conducted by researchers from Hospital for Special Surgery (HSS) suggest that lower socioeconomic status at the community level significantly increases the risk of pain and poor function following a knee replacement.

ORLANDO, Florida, Nov. 9, 2015 -- Registering with more than one organ transplant center appears to give an edge to wealthy patients over those with the most medical need, according to research presented at the American Heart Association's Scientific Sessions 2015.

Researchers studied the national database of organ donors from 2000 to 2013 and found that patients who simultaneously listed at more than one center had higher transplant rates, lower death rates while waiting, were wealthier and were more likely to be insured.

Patterned with star-like figures on their shells, Indian star tortoises can be found in private homes across Asia, where they are commonly kept as pets. One can also see them in religious temples, praised as the living incarnation of the Hindu god Vishnu. How did they get there? Suspicious of a large-scale illegal international trade of these tortoises that could in fact pose a grave threat to the survival of the Indian Star tortoise, a team of researchers, led by Dr.

A team of scientists, led by researchers at The University of Texas MD Anderson Cancer Center and University of California, San Diego Moores Cancer Center, report that a genetic biomarker called loss of heterozygosity or LOH is able to predict which patients with premalignant mouth lesions are at highest risk of developing oral cancer.

The 2015 growing season was a tough one for tomato researchers at the Boyce Thompson Institute, as bacterial speck disease descended on their field, but those infected plants may one day save others from a similar, spotted fate.

Cool weather and heavy rains in early summer created the perfect environment for speck--a bacterial disease that attacks tomatoes, causing dark spots on leaves and fruits and withered flowers. The outbreak of speck turned Boyce Thompson Institute's tomato field in Freeville, New York into a withered, mottled mess.

A new study indicates that a meat-rich diet may increase the risk of developing kidney cancer through mechanisms related to particular cooking compounds. Also, these associations may be modified by genetic susceptibility to kidney cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study illustrates how diet and genetics may interact to impact cancer risk.

They are as ubiquitous in the Arab world as camels and shifting sands, and its fruit is required eating at special occasions and during Muslim holidays. Yet as inseparable as the date palm might seem from today's Middle East, one question remains: how did they become what they are today?

Now, researchers at NYU Abu Dhabi have developed a map of genetic changes across the genome of date palms. They have also established genetic differences between Middle Eastern and North African date palms, an important discovery that sheds light on that long elusive question.

Diets high in meat may lead to an increased risk of developing renal cell carcinoma (RCC) through intake of carcinogenic compounds created by certain cooking techniques, such as barbecuing and pan-frying. As part of a new study from The University of Texas MD Anderson Cancer Center, published online this week in the journal CANCER, researchers also discovered that individuals with specific genetic mutations are more susceptible to the harmful compounds created when cooking at high temperatures.

Would your ability to resist a tantalizing cookie improve if you had to wait a few seconds before you could reach for it? The idea that natural urges 'die down' with time seems intuitive, but new research shows that it's being reminded about what not to do, not the passage of time, that actually helps young children control their impulsive behavior.

The findings are published in Psychological Science, a journal of the Association for Psychological Science.

November 9, 2015 - In the largest genomic analysis of puberty timing in men, new research conducted by scientists at the University of Cambridge and 23andMe* shows that the timing of puberty in males and females is influenced by many of the same-shared genetic factors. The study results are the first to quantify the strongly shared genetic basis for puberty timing between the sexes.

Drinking one 16-ounce energy drink boosts blood pressure and stress hormone responses in young, healthy adults, according to a study presented at the American Heart Association's Scientific Sessions 2015. These changes could conceivably trigger new cardiovascular events.

High job demands, stress and job insecurity are among the main reasons why people go to work when they are ill, according to new research by an academic at the University of East Anglia (UEA).

The study aims to improve understanding of the key causes of employees going to work when sick, known as presenteeism, and to help make managers more aware of the existence of the growing phenomenon, what triggers the behaviour and what can be done to improve employees' health and productivity.

Anna Svatikova, M.D., Ph.D., of the Mayo Clinic, Rochester, Minn., and colleagues randomly assigned 25 healthy volunteers (age 18 years or older) to consume a can (480 mL; 16 fl. oz.) of a commercially available energy drink (Rockstar; Rockstar Inc) and placebo drink within 5 minutes, in random order on 2 separate days, maximum 2 weeks apart.

Research into a simple, accurate and low risk blood test that can detect foetal blood group, sex, and genetic conditions in unborn babies has been published in the international scientific journal, Clinical Chemistry.

The research is the result of a collaboration between Plymouth Hospitals NHS Trust and Plymouth University. The DNA test costs pence and is non-invasive - as opposed to the traditional amniocentesis test that is available on the NHS, involves a needle and carries a minor (1%) risk of miscarriage.
