Using gene-editing technology to create virus-resistant cassava plants could have serious negative ramifications, according to new research by plant biologists at the University of Alberta, the University of Liège in Belgium and the Swiss Federal Institute of Technology.
When winter comes, populations of red-neck phalarope from the Western Palearctic migrate to two different destinations -the Pacific Ocean or the Arabian Sea- following an exceptional migratory divide strategy which has never been described in this geographical area.
Blogs, or as they were originally known, weblogs, first hit the World Wide Web back in 1997. The term "weblog" was coined in December that year and almost immediately abbreviated to "blog".

There has to be a better way of doing work.
Nearly 50 years since man first walked on the moon, the human race is once more pushing forward with attempts to land on the Earth's satellite. This year alone, China has landed a robotic spacecraft on the far side of the moon, while India is close to landing a lunar vehicle, and Israel continues its mission to touch down on the surface, despite the crash of its recent venture. NASA meanwhile has announced it wants to send astronauts to the moon's south pole by 2024.
For biologists everywhere, April 25 is auspicious. It is DNA Day and commemorates the date in 1953 when scientists Francis Crick, Rosalind Franklin, James Watson and Maurice Wilkins published seminal scientific papers describing the helical structure of the DNA molecule. In 2003, April 25 was used to announce the completion of the Human Genome Project. Now annual festivities on this day celebrate the molecule of life with new discoveries. What better time to provide a new picture of DNA.
A joint Mongol-Japanese research team from the National University of Mongolia and Kanazawa University conducted the first detailed study of organic air pollutants in Ulaanbaatar city. The polycyclic aromatic hydrocarbon (PAH) contents of airborne particulates were determined, and indicated that the degree of air pollution varies markedly by district and season.
