Improved lifestyle led to decreased cholesterol and less cardiac death

Cholesterol levels — the most common risk factor for heart attacks — have decreased in northern Sweden over the last 20 years. Since medical drugs only account for a third of the decrease, the reduced risk of cardiovascular disease is greatly thanks to a change in lifestyle. This according to a study published in the European Heart Journal.

Formaldehyde exposure from 3 e-cigarette formats tested well below WHO quality guidelines

A new study shows that the daily exposure to formaldehyde from three different types of e-cigarettes is well below the levels considered safe by the World Health Organisation — at less than a sixth of the indoor air quality standard. For all products tested, formaldehyde levels were also well below a number of other formaldehyde safety benchmarks such as the threshold for throat and respiratory tract irritation, the European REACh Derived No Effect Level and occupational exposure guidelines.

Increased protein consumption linked to feelings of fullness: New study

Many people turn to high-protein foods when trying to lose weight because eating protein-rich meals is commonly believed to make dieters feel fuller. Surprisingly, this idea hadn’t been tested on a large scale. In a new study featured in the Journal of the Academy of Nutrition and Dietetics, researchers conducted a systematic review of the evidence on the effect of protein intake on perceived fullness and confirmed that protein does, in fact, make us feel fuller.

How well did an instant blood pressure app work?

A blood pressure (BP) smartphone app delivered inaccurate results in a small study, which suggests more than three-quarters of individuals with hypertensive BP levels may be falsely reassured that their BP is in the nonhypertensive range, according to an article published online by JAMA Internal Medicine.

Study explores how high-fat diet influences colon cancer

A study published in Nature reveals how a high-fat diet makes the cells of the intestinal lining more likely to become cancerous. The new study of mice suggests that a high-fat diet drives a population boom of intestinal stem cells and also generates a pool of other cells that behave like stem cells — that is, they can reproduce themselves indefinitely and differentiate into other cell types. These stem cells and ‘stem-like’ cells are more likely to give rise to intestinal tumors.

Researchers map how marine mammals interact with their prey

A team led by Northeastern University Professor Purnima Ratilal has mapped a mass feeding frenzy involving more than eight highly protected species of whales and dolphins in the US Gulf of Maine region. It is the first time researchers have observed predator and prey interactions in the wild over such a vast expanse, including specific species’ feeding behaviors. Understanding how the two relate could have important implications for conserving marine ecosystems.

Next-generation immunotherapy offers new hope for beating brain cancer

IRB Barcelona identifies GEMC1 as a master gene for the generation of multiciliated cells — cells with fine filaments that move fluids and substances — which are found exclusively in the brain, respiratory tract, and reproductive system.Defects in multiciliated cells lead to ciliopathies — rare and complex diseases that are poorly understood and for which not all causative genes have been identified.

Metamaterial separation proposed for chemical, biomolecular uses

The unique properties of metamaterials have been used to cloak objects from light, and to hide them from vibration, pressure waves and heat. Now, a Georgia Institute of Technology researcher wants to add another use for metamaterials: creating a new directional separation technique that cloaks one compound while concentrating the other.

Some bacterial CRISPRs can snip RNA, too

Did you know the CRISPR/Cas9 system was derived from bacteria, which use it to fight off foreign invaders such as viruses? It allows many bacteria to snip and store segments of DNA from an invading virus, which they can then use to ‘remember’ and destroy DNA from similar invaders if they are encountered again. Recent work demonstrates that some bacteria also use the CRISPR/Cas system to snip and recognize segments of RNA, not just DNA.
