Methane (CH4) is a powerful greenhouse gas: the emission of one ton of methane has an effect equivalent to 21 tons of carbon dioxide (CO2).
Given that a cow can produce up to 500 liters of gas daily, the environmental impact of livestock is quite significant: in Alberta, cattle are the second largest emitters of greenhouse gases after the oil industry. Hence the interest of a recent study conducted jointly by the Universities of Alberta, Manitoba and Guelph, AAFC (Agriculture and Agri-Food Canada) and IAEA (International Agency for Atomic Energy) and …

Iran – Researchers at the University of Tehran have found a supplement coenzyme Q10 which can improve sperm quality in men of low fertility.
A sperm must travel some distance to reach the egg. For that it needs a lot of energy. When a man produces spermatozoa in small quantity that has less mobility, its fertility is compromised.
Vitamin and antioxidant, coenzyme Q10 is found naturally in all body cells. 95% of all body energy needs are processed through this coenzyme. Because sperm are sensitive to oxidative stress, the researchers wanted to …

Taiwan – Scientists at the University National Yang-Ming discovered a gene that could hold the secret to human longevity. This discovery came during research into the identification of a gene linked to liver cancer.
The gene is called CISD2 and is located on chromosome 4. In mice deprived of this gene, signs of premature aging have been recognized as the discoloration of hair and loss of bone mass. An animal deprived of this gene is also showing signs of life expectancy decreasing by half.
A study 8 years ago had shown that …
