University of Illinois dining halls voluntarily label foods with nutrition information.Although 45 percent of students noticed the labels, only 20 percent used the labels. Rates of label awareness and use did not change over the course of the semester.Students who practice health-promoting behaviors like tracking what they eat or exercising frequently are most likely to use nutrition information on food items in the dining hall.Placement of the labels directly in front of the food or above the sneeze guard doesn't affect label awareness or use.

DALLAS - June 29, 2016 - UT Southwestern Medical Center cell biologists have identified a new method for determining the length of telomeres, the endcaps of chromosomes, which can influence cancer progression and aging.
The spread of cancer from a tumor's original location to other parts of the body can play a major role in whether the disease turns deadly. Many steps in this process, called metastasis, remain murky. But now scientists are gaining new insights into how cancer cells might squeeze through and even divide within narrow blood vessels while travelling in the body. They report their study using microtubular nanomembranes in the journal ACS Nano.
Anxiety over the Zika virus is growing as the Olympic Games in Rio de Janeiro approach. To better diagnose and track the disease, scientists are now reporting in ACS' journal Analytical Chemistry a new $2 test that in the lab can accurately detect low levels of the virus in saliva.
Overeating can lead to health issues that can shorten one's life, such as obesity, diabetes and heart disease. On the other end of the spectrum, several studies have shown that restricting calorie intake below what a normal diet would dictate may lead to a longer life. In an animal study, scientists now report in ACS' Journal of Proteome Research the metabolic reasons why these opposite diets may lead to such differences in longevity.
June 29, 2016 - Last year, the most extensive clinical face transplant to date was successfully carried out at NYU Langone Medical Center.
June 29, 2016 - Plastic surgeons see some clear advantages of using Google Glass in the operating room, reports a survey study in the July issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
Tumor DNA is cluttered with genomic alterations, the vast majority of which have little or no functional or clinical relevance. This means that even when cancer researchers discover an alteration in a tumor or a line of cancer cells, the alteration may or may not be relevant to the progression of the disease - chances are good (and history has shown) that many alterations that are correlated with cancer are not causative of cancer; many alterations are "passengers" rather than "drivers".
When a cell makes copies of DNA and translates its genetic code into proteins at the same time, the molecular machinery that carries on replication and the one that transcribes the DNA to the mRNA code move along the same DNA double strand as their respective processes take place. Sometimes replication and transcription proceed on the same direction, but sometimes the processes are in a collision course. Researchers at Baylor College of Medicine and the University of Wisconsin have determined that these collisions can significantly contribute to mutagenesis.
Zika virus infection confers protection against future infection in monkeys, but lingers in the body of pregnant animals for prolonged periods of time, according to research funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). The findings appear in the June 28 issue of Nature Communications.
In an article published online April 16, 2016 by the Journal of Neurointerventional Surgery, investigators at the Medical University of South Carolina (MUSC) report promising 90-day outcomes for stroke patients with large-vessel clots who underwent thrombectomy or clot removal using the direct-aspiration, first pass technique (ADAPT). Approximately 58% of stroke patients with a large-vessel clot removed using the technique achieved a good outcome at 90 days, defined as a Modified Rankin Score (mRS) of 0 to 2.
ANN ARBOR, Mich. -- In a western doctor's office or hospital, patients don't think twice about giving a blood or urine sample that can tell if they have a disease or infection, or show if their medicines are working. The samples get rushed to a testing lab with modern equipment that's held to high quality standards.
But in developing nations, many of those tests aren't available. Or if they are, doctors may not put much faith in them because of the state of their country's testing labs.

Researchers have used genetic sequencing to show that the 2009 global H1N1 influenza pandemic began in central Mexico, originating in pigs and spreading to humans. Mexico is not typically considered a source of novel influenza strains. The new findings appear online in the journal eLIFE. They shed light on how the novel virus evolved and stress the need for improved influenza surveillance. The research was supported by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health,
An international joint research group succeeded in developing a novel thermally activated delayed fluorescence (TADF) material which displays emission of light in colors from green to deep-red through Intersystem Crossing from the singlet to the triplet excitons, a world first. The results will contribute to R&D in white TADF light emitting devices for indoor and outdoor use through combination with TADF materials that emit light in shorter wavelengths (deep blue to yellow).
COLUMBUS, Ohio--What if testing yourself for cancer or other diseases were as easy as testing your blood sugar or taking a home pregnancy test? In a few years, it might be.
Chemists at The Ohio State University are developing paper strips that detect diseases including cancer and malaria--for a cost of 50 cents per strip.
