A new study from the University of Eastern Finland shows that a relatively high intake of dietary cholesterol, or eating one egg every day, are not associated with an elevated risk of incident coronary heart disease. Furthermore, no association was found among those with the APOE4 phenotype, which affects cholesterol metabolism and is common among the Finnish population. The findings were published in the American Journal of Clinical Nutrition.

For years, scientists have failed to locate the DNA variants that control the weight-regulating hormone, leptin. However, new research has enabled the identification of four genes associated with leptin levels, which is particularly relevant within an obesity context. The study focuses on the powerful hormone leptin, which regulates humans' long-term energy balance by informing the brain about the amount of stored body fat.

While studying the abundant, yet poorly known fauna of the zoantharian Epizoanthus genus in the Indo-Pacific Ocean, Japanese graduate student Hiroki Kise and Dr. James Davis Reimer, both affiliated with University of the Ryukyus, Japan, focused on examining the species living on eunicid worm tubes. These Epizoanthus species form colonies and are only found living on the outside surfaces of tubes in which the eunicid worms live.

The huge variability among the desert tortoise populations of Mexico has finally been given an explanation after casting doubts for several decades. The puzzle was solved by an international team of researchers, led by Dr. Taylor Edwards, The University of Arizona, who teamed up to find out whether there has been a previously unknown third sister species all along. Moreover, unlike their predecessors, the team have managed to provide enough evidence to prove its existence.

A research team from the University of Liverpool has reached an important milestone towards creating a urine diagnostic test for prostate cancer that could mean that invasive diagnostic procedures that men currently undergo eventually become a thing of the past.

'The use of a gas chromatography (GC)-sensor system combined with advanced statistical methods towards the diagnosis of urological malignancies', published today in the Journal of Breath Research, describes a diagnostic test using a special tool to 'smell' the cancer in men's urine.

ROCHESTER, Minn. -- Building on previous studies, Mayo Clinic researchers have demonstrated significant health improvements in the vascular system of mice following repeated treatments to remove senescent cells. They say this is the first study to show that regular and continual clearance of senescent cells improves age-related vascular conditions - and that the method may be a viable approach to reduce cardiovascular disease and death. The findings appear online in Aging Cell.

The Oxford Dictionaries selected "vape"--as in, to smoke from an electronic cigarette--as word of the year in 2014. It turns out that Internet users' search behavior tells a similar story.

Between 2009 and 2015, the number of people in the United States seeking information online about vaping rose dramatically, according to a recent study co-led by San Diego State University Internet health expert John W. Ayers and University of North Carolina tobacco control expert Rebecca S. Williams as a part of the Internet Tobacco Vendors Study.

The UK's new alcohol guidelines are unlikely to have a direct impact on drinking, but they do raise awareness of harm and so may alter social attitudes towards alcohol, suggests an expert in The BMJ today.

Professor Theresa Marteau, Director of the Behaviour and Health Research Unit at the University of Cambridge - and a member of the committee that produced the guidelines - says while there is little direct evidence about any impact of health related guidelines on behaviour, including for alcohol, novel risk information can change behaviour.

The risk of death by age two among infants born before 28 weeks' gestation is up to 45 per cent higher when they receive targeted oxygen saturation in the range of 85-89 per cent compared to 91-95 per cent, according to a paper published today in the New England Journal of Medicine.

Conducted in Australia and the UK by the BOOST-II Collaborative Groups, the trial involved 2,108 cases and confirms similar findings from a randomised controlled trial in North America.

(Boston)--Despite the concern of an explosion of dementia cases in an aging population over the next few decades, a new study, based on data from the Framingham Heart Study (FHS), suggests that the rate of new cases of dementia actually may be decreasing.

These findings, which appear in the New England Journal of Medicine, provide hope that some cases of dementia might be preventable or delayed and encourages funding agencies and the scientific community to further explore demographic, lifestyle and environmental factors underlying this positive trend.

Here's some incentive to cover your mouth the next time you sneeze: New high-speed videos captured by MIT researchers show that as a person sneezes, they launch a sheet of fluid that balloons, then breaks apart in long filaments that destabilize, and finally disperses as a spray of droplets, similar to paint that is flung through the air.

The extremely complex geological history of New Guinea has allowed many of its animals and plants the chance to grow different enough to make a name for themselves. In the case of two newly described and unusually large gecko species - only a noble name would do. The two new species whose names respectively mean 'knight' and 'king' were discovered by a team led by Dr.

Gone are the days of spending a day to submit an article to be published. A new journal is challenging established methods in biomedical research publications. Pathogens and Immunity streamlines the current research publication process -- a well-recognized source of frustration for biomedical researchers -- from one day to five minutes.

Report describes first known case of Zika in U.S. resident returning from Costa RicaFree content: http://www.annals.org/article.aspx?doi=10.7326/L16-0075

A report published in Annals of Internal Medicine describes the first known case of Zika virus in a U.S. resident following travel to Costa Rica. The author discusses the traveler's symptoms, what his test results showed, and the health status of the family members who traveled with him.

From paper towels to cups to plastic bottles, products made from recycled materials permeate our lives. One notable exception is building materials. Why can't we recycle concrete from our deteriorating infrastructure for use as material in new buildings and bridges? It's a question that a team of researchers at the University of Notre Dame is examining.
