Data from 1,302 participants indicated that flaxseed supplements are associated with significant reductions in both systolic and diastolic blood pressure of about 2.85 mmHg and 2.39 mmHg, respectively. “The results obtained in the present meta-analysis – a decrease of 2.85/2.39 mmHg after flaxseed supplementation – might be valuable for the hypertension management using nutraceuticals, since Heart Outcome Evaluation study demonstrated …
When it comes to producing drugs like heroin and cocaine, science is on the verge of a revolutionary breakthrough that could disrupt traditional drug markets by making it possible for anyone to produce their own. Researchers working with genetically engineered yeasts are rapidly advancing toward the point where all it would take is some humble fungi and a home-brewing kit. …
Dogs’ special relationship to humans may go back 27,000 to 40,000 years, according to genomic analysis of an ancient Taimyr wolf bone reported in the Cell Press journal Current Biology on May 21. Earlier genome-based estimates have suggested that the ancestors of modern-day dogs diverged from wolves no more than 16,000 years ago, after the last Ice Age. The genome from this …
In addition to the ethical questions and the serious unintended health consequences, this would also open the door to patenting human DNA. Action Alert! Late last month, a group of Chinese scientists published a study that tried to answer the question, “Is it possible to edit the genetic makeup of human embryos?” It’s a question that has occupied scientists and medical researchers for …
We’ve always known that anxiety takes a toll on the human body. Anxious people are more likely to suffer from heart disease and other diseases, for example. To date, however, we haven’t been too sure about anxiety’s effects on aging. Interestingly enough, a new study shows anxiety shortens telomeres, the end caps of DNA. The results were published online in …
AH, MY SWEET summer child. What do you know of inflammation? Inflammation is for the winter, when genes uncoil in your blood and messengers send codes containing the blueprints for proteins to protect you from the harsh diseases of the cold. Inflammation is for those long nights, when the sun hides its face, or rain clouds block the sky, and trillions …
Researchers report that as the world population increases and food demand has grown, globalization of trade has made the food supply more sensitive to environmental and market fluctuations. This leads to greater chances of food crises, particularly in nations where land and water resources are scarce and therefore food security strongly relies on imports. The study assesses the food supply available to …
Over the past several weeks, we’ve seen so many examples of brutality played out in our cities — and mostly our most impoverished areas — that it isn’t difficult to see why so many people are in the streets. Many say white people cannot truly understand the deep racial issues that target African American people and their communities, and that …
The genetic modification of humans make many people feel very uncomfortable. Credit: Tatiana Vdb/Manuel/Flickr, CC BY It all started with a rumour. Then just six weeks ago, a warning rang out in the scientific journal Nature, expressing “grave concerns regarding the ethical and safety implications” of creating the world’s first genetically-modified human embryo. Then last week, a Chinese group from Sun Yat-sen …
Four chemicals present both inside and outside homes might disrupt our endocrine systems at levels considered safe by the U.S. Environmental Protection Agency, according to an analysis released today. The chemicals – benzene, toluene, ethylbenzene and xylene – are ubiquitous: in the air outside and in many products inside homes and businesses. They have been linked to reproductive, respiratory and heart …
