exercise for younger heart, arteries
Exercising four to five times a week is necessary to stop the main arteries to the heart from stiffening up, research suggests. Two or three exercise sessions a week kept only some arteries healthy, a study of 100 people in their 60s found. The researchers said any form of exercise reduced the risk of heart problems. But the right amount of exercise at the right time in life could reverse the ageing of the heart and blood vessels. The study, published in The Journal of Physiology, looked at participants' exercise history throughout their lives and measured the stiffness of their arteries. Arteries are blood vessels which transport blood in and out of the heart and to all parts of the body. Each one is shaped like a tube and as people age, they are prone to stiffening. An unhealthy lifestyle also causes the arteries to become blocked with fatty material. The researchers found that exercising two to three times a week (30 minutes per session) over a lifetime led to more youthful middle-sized arteries supplying blood to the head and neck.
trumped by the diff. b/w hiv and hpv
The top trade association for the adult entertainment industry is trolling President Trump with an open letter explaining the difference between HIV and HPV. The letter from the Free Speech Coalition comes after recently released footage of Bill Gates revealed that Trump had asked him to explain the difference between the two viruses. “We understand that science is hard, and certainly a challenging concept for people who do not believe in facts,” the letter reads. “However, your willingness to acknowledge your own ignorance is the first step in the learning process. There is no such thing as a silly question when it is coming from someone with direct access to nearly half the world’s nuclear arsenal.”
it’s robots versus cancer
The diagnosis of cancer and other diseases in the UK can be transformed by using artificial intelligence, Theresa May is to say. The NHS and technology companies should use AI as a “new weapon” in research, the PM will urge in a speech later. Experts say it can be used to help prevent 22,000 cancer deaths a year by 2033 while aiding the fight against heart disease, diabetes and dementia. High-skilled science jobs will also be created, Mrs May is to pledge. Speaking in Macclesfield, Mrs May will say: “late diagnosis of otherwise treatable illnesses is one of the biggest causes of avoidable deaths. And the development of smart technologies to analyse great quantities of data quickly and with a higher degree of accuracy than is possible by human beings opens up a whole new field of medical research.”
