A fossil creature buried in an “invertebrate version of Pompeii” more than half a billion years ago reveals the first-known cardiovascular system in exquisitely preserved detail.

An international team of researchers from the University of Arizona, China and the United Kingdom has discovered the earliest known cardiovascular system, and the first to clearly show a sophisticated system complete with heart and blood vessels, in fossilized remains of an extinct marine creature that lived over half a billion years ago. The finding sheds new light on the evolution of body organization in the animal kingdom and shows that even the earliest creatures had internal organizational systems that strongly resemble those found in their modern descendants.

COLUMBUS, Ohio – Taking enough omega-3 fatty acid supplements to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests.

The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve tiny segments of DNA in their white blood cells. (more…)

Pollution is an unfortunate by-product of our ever-changing society. Air, water and even noise pollution can take a toll on any person’s body, without their knowledge. Fortunately, there ARE ways to fight the effects of pollution in your body, in order to maintain a healthy lifestyle. There are also helpful tips to decrease the toxins that are invading your body, which could potentially cause harmful consequences later in life. Here’s what you need to know!

The Consequences of Pollution

Impure surroundings affect the lungs, heart, cardiovascular system, immune system, and organs when dangerous toxins are inhaled, consumed or absorbed by the skin or airways. Respiratory ailments, such as colds, flu, pneumonia, emphysema and bronchitis occur often because of these. The chances of contracting asthma and COPD or Chronic Obstructive Pulmonary Disease are also more likely. Tainted environments also contribute to allergies, headaches, migraines, and skin disorders such as eczema, acne, melanoma cancer and premature aging. (more…)

New research into the health benefits of beetroot juice suggests it’s not only athletes who can benefit from its performance enhancing properties – its physiological effects could help the elderly or people with heart or lung-conditions enjoy more active lives.

Beetroot juice has been one of the biggest stories in sports science over the past year after researchers at the University of Exeter found it enables people to exercise for up to 16% longer. (more…)
