The uplifting effects of energy drinks are well advertised, but a new report finds consumption among teenagers may be linked with poor mental health and substance use.Researchers are calling for limits on teen's access to the drinks and reduction in the amount of the caffeine in each can.The paper by researchers at the University of Waterloo and Dalhousie University, published in Preventive Medicine, found that high school students prone to depression as well as those who are smoke marijuana or drink alcohol are more likely to consume energy drinks than their peers.
It is now common knowledge that having too much fat is bad for you, but less well known is the serious threat posed by the "hidden fat" that surrounds our vital organs. New research published in the journal Nature Cell Biology claims to have discovered where this hidden, or "visceral fat," comes from.Visceral fat and subcutaneous fat are the two main types of fat in the body. Subcutaneous fat is found directly beneath the skin - it gives our bodies cushioning and insulation and is a store of energy. Visceral fat, meanwhile, develops around the heart, intestines and vital organs.
The American Cancer Society estimate that there will be 12,360 new cases of invasive cervical cancer diagnosed this year, with 4,020 deaths from the disease. Now, a phase II trial has found that a targeted antitumor drug could prolong the survival of women with cervical cancer.The research team, led by Dr. Angélica Nogueira-Rodrigues of the Brazilian National Cancer Institute, recently published their findings in the journal Cancer.
It is no surprise that more than 91.4 million Americans use a smartphone. The devices are so much more than a phone - they are a world of knowledge right in the palms of our hands. And now, they can even monitor our health. Technology company Azoi has launched a smartphone case that can measure key vital signs.The health tracker is called Wello. It consists of a number of sensors that are embedded into a case that fits onto a smartphone.
With one in seven humans undernourished, and with the challenges of population growth and climate change, the need for efficient food production has never been greater. Eight strategies to cut the environmental and economic costs of keeping livestock, such as cows, goats and sheep, while boosting the quantity and quality of the food produced have been outlined by an international team of scientists.
The results, published in The New England Journal of Medicine and Human and Molecular Genetics journals, demonstrate for the first time that mutation in STAG3 gene is the major cause of human fertility disorders as it provokes a loss of function of the protein it encodes.STAG3 encodes a meiosis-specific subunit of the cohesin ring, the biological process through which, from a diploid somatic cell, a haploid cell or gamete is produced.
Three promising biomarkers being studied to detect Alzheimer's disease in its early stages appear to undergo a surprising shift as patients develop symptoms of dementia, researchers at Washington University School of Medicine in St. Louis report.Scientists use the biomarkers to assess brain changes linked to the disease in research volunteers.
To reconstruct phylogenetic trees from next-generation sequencing data using traditional methods requires a time-consuming combination of bioinformatic procedures including genome assembly, gene prediction, orthology identification and multiple alignment. As a consequence, more recently, scientists have relied on a simpler method where short sequence reads from each species are aligned directly to the genome sequence of a single reference sequence.The authors, Bertels, et. al.
In many primates, females mate with multiple partners, causing an often-intense competition amongst males to pass along their DNA to be king of the genome as well as the jungle.In the advanced online edition of Molecular Biology and Evolution, author Alex Wong used a published sequence dataset from 55 species of primates to test for a correlation between molecular evolutionary rates across a genome (substitution rates) and testes weights, used in the study as a proxy for increased sperm production and competition.
Ludwig researchers show that infecting just 1 tumor with a virus could boost the systemic effectiveness of cancer immunotherapy
A Ludwig Cancer Research study suggests that the clinical efficacy of checkpoint blockade, a powerful new strategy to harness the immune response to treat cancers, might be dramatically improved if combined with oncolytic virotherapy, an investigational intervention that employs viruses to destroy tumors.
Early Lapita inhabitants of Vanuatu, a South Pacific Island, ate fish, marine turtles, and wild or domestic animals, rather than relying on horticulture during early colonization, according to a study published March 5, 2014, in the open-access journal PLOS ONE by Rebecca Kinaston from University of Otago in New Zealand and colleagues.
Studies have shown that individuals who are socially anxious prefer to communicate with others online rather than face to face. Social networking sites, such as Facebook, give them the opportunity to do just that. But how does this initial virtual interaction impact face-to-face interaction later on? A new study investigates.Researchers from Benedictine University at Mesa, AZ, and the Providence College in Rhode Island published their findings in the journal Cyberpsychology, Behavior, and Social Networking.
Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme precision of measurements. The results are published in the prestigious scientific journal, Nature.
Researchers at New York University have identified the nature of brain activity that allows us to bridge time in our memories. Their findings, which appear in the latest issue of the journal Neuron, offer new insights into the temporal nature of how we store our recollections and may offer a pathway for addressing memory-related afflictions.
Human activity influences ocean beach bacterial communities, and bacterial diversity may indicate greater ecological health and resiliency to sewage contamination, according to results published March 5, 2014, in the open access journal PLOS ONE by Elizabeth Halliday from Woods Hole Oceanographic Institution and colleagues.Beaches all contain bacteria, but some bacteria are usually from sewage and may contaminate the water, posing a public health risk.
Though present in more than 6,000 living species of fish, the adipose fin, a small appendage that lies between the dorsal fin and tail, has no clear function and is thought to be vestigial. However, a new study analyzing their origins finds that these fins arose repeatedly and independently in multiple species. In addition, adipose fins appear to have repeatedly and independently evolved a skeleton, offering a glimpse into how new tissue types and structural complexity evolve in vertebrate appendages.
The extent to which alcohol impairs the driving abilities of different age groups has been put to the test using a computer simulation. The researchers behind the investigation, from the University of Florida, publish their findings in the Psychopharmacology journal.The team tested two age groups, people aged 25 to 35 and people aged 55 to 70.The participants' driving abilities were measured in a task that had them drive down a simulated winding 3-mile stretch of country road.
The main role of the kidney is to filter waste products from the blood before converting them into urine. But this process ceases for individuals who have kidney failure, causing waste to build up in their blood. Now, researchers have created a nanofiber mesh that they say could be a wearable and cheaper alternative to kidney dialysis.This is according to a study published in the journal Biomaterials Science.Kidney dialysis is the most common treatment for patients with kidney failure.
Since the days of Darwin, scientists have considered bird song to be an exclusively male trait, resulting from sexual selection. Now a team of researchers from the University of Maryland, Baltimore County (UMBC), the University of Melbourne in Australia, Leiden University in the Netherlands and The Australian National University says that's not the whole story.The team used information from several sources, including the Handbook of the Birds of the World.
Described by the Centers for Disease Control and Prevention as "physical, sexual, or psychological harm by a current or former partner or spouse," intimate partner violence (IPV) is a serious public health issue affecting millions of people in the United States. New research from sociologists at Bowling Green State University (BGSU) shows that adolescents and young adults who perpetrate or fall victim to IPV are more likely to experience an increase in symptoms of depression.
