Atherosclerosis, a condition that causes arteries to thicken, is a risk factor for a number of diseases that as a group are the leading cause of death in the U.S. What it really means, why it happens, and why it matters is unclear, since nearly half of Americans are told they have it.

Understanding its progression and possible impact of fatty buildup in the arteries is important, as is calcification. A new pilot is geared toward learning where that calcification comes from, and if perhaps its origin is inside the arteries.

A survey of over one thousand Tinder users found that were not interested in meeting anyone, and nearly two-thirds were already married or "in a relationship."

Instead of being used to find dates, people instead it has a similar appeal as social media - a source of entertainment, distraction and self-esteem.

The data were 1,387 English-speaking Tinder users, ages 17 to 84, asking about their motivations for using the app; the number of matches and offline dates they had; their relationship status; their selectiveness in choosing partners; and, among other factors, psychological measures like impulsivity, depression, loneliness and self-esteem.

Food waste is a major problem in the developed world. People new to buying organic food are annoyed at how quickly it spoils but what if that wilted brown lettuce could be converted into energy?

Anaerobic digestion hasn't been done on a large scale, the numbers don't work, but academics say it could. In a numerical model. The authors looked at supply chain logistics - potential sites, transportation, production, and facility costs, as well as revenue and return on investments.

A new study is actively recruiting men and women of African ancestry who were diagnosed with prostate or breast cancer to build a database from which researchers hope to identify genetic factors that may influence cancer risk among these groups.

A decade ago surveys showed that Millennials were less concerned about environmental claims than Baby Boomers or Generation X. The reason was speculated to be environmental fatigue. Millennials saw that government recycling was only making China rich and Americans pay higher taxes, that being miserable at home while Al Gore got rich selling carbon credits made no sense, and assurances that weather were not climate during a snowstorm but were climate during a heatwave made little sense.

The discovery of new biomarkers is important for detecting ovarian cancer, as the disease is difficult to detect in its early stages where it can most easily be treated.

One approach to detecting cancer is to look for extracellular vesicles (EVs), especially small proteins released from the tumor called exosomes. As these proteins are found outside the cancer cell, they can be isolated from body fluids, such as blood, urine, and saliva. However, the use of these biomarkers is hindered by the lack of reliable ones for the detection of ovarian cancer.
