You may not yet have heard of chylomicrons, but a nutritional scientist at the University of Alberta believes you will soon--especially if you care about preventing a stroke or heart attack.
Dr. Spencer Proctor says chylomicrons gather on arterial walls and may be as dangerous or more dangerous than low-density lipoprotein (LDL) cholesterol in causing strokes and heart attacks. "We were the first in the world to label chylomicrons remnants with florescence and visually show that these particles can accumulate in arterial vessels," Proctor said. "Our next goal is to figure out why they get stuck and whether or not they play a significant role in the development of coronary artery disease--our suspicion now is that they do."
Chylomicrons are metabolized balls of fat and cholesterol that enter the blood stream through the intestines after a meal--usually within about 15 minutes after your last bite. However, because chylomicrons are processed so quickly, when a patient gives a blood sample after fasting for 12 hours or more, as per doctors usual orders, chylomicron cholesterol will usually comprise just three per cent of all the cholesterol in the sample. LDL cholesterol is the most prevalent type of cholesterol, usually comprising about 70 per cent of all cholesterols found in blood samples taken from patients who have fasted for 12 hours or more.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
