An increasing amount of genetic engineering in agriculture closely resembles the conventional crop breeding that has been done for thousands of years, and unnecessarily stringent regulation of this type of gene research is choking off its usefulness, one expert says in a new policy forum in Science.
Government regulations that lump all types of genetic engineering together, instead of making reasonable distinctions between differing technologies, is stifling research, favors the efforts of
Is there life on Mars? It’s possible, but it may not be Martian, say scientists. New research, published in the open access journal BMC Microbiology, suggests that conditions on Mars are capable of supporting dormant bacteria, known as endospores. This raises concern about future attempts to detect Martian life forms because endospores originating on Earth could potentially hitch a ride to Mars and survive on its surface.
Soil on Mars is thought to be rich in oxidising chemicals that are known
Our post-ice-age climate is not nearly as stable as is commonly believed. New evidence for this is reported by geoscientists of the DFG Research Center Ocean Margins in the upcoming issue of the journal Science. Investigating marine sediments from the northern Red Sea, they discovered that this currently very dry region was influenced by a long wet period between 9,000 and 6,500 years ago. It was characterized by a monsoon-like system during that time. The possibility that this Mediterranean monsoon
A bit of Earth-bound chemistry has led scientists at the University of California, Berkeley, to conclude that there is an unsuspected wind of low-energy cosmic ray particles blowing through the galaxy.
The cosmic rays arent energetic enough to make headway against the solar wind to reach Earth, but they appear to have a big impact on the chemistry within tenuous clouds of gas between stars, so-called diffuse interstellar clouds.
“This implies a new population of cosmic rays no
Many shark species, including the great white and mako, swim at speeds greater than their morphology should allow. Dr. Adam Summers (University of California) has discovered they achieve this speed by changing the stiffness of their body by pressurising their thick, inflexible skin. “This study could help answer questions about the evolution of the shark, especially why sharks abandoned a bony skeleton in favour of a cartilage structure,” said Dr. Summers who will be presenting his findings on Frida
Special modification of reverse genetics created at St. Jude allowed vaccine to be custom-made within weeks of emergence of virus
Scientists at St. Jude Childrens Research Hospital announced today the development of a vaccine against H5N1, a new lethal influenza virus that triggered the World Health Organization (WHO) to declare a pandemic alert in February 2003.
The virus appeared in birds in Hong Kong late last year and subsequently killed one of two infected people
