Scientists pull living microbes, possibly 100 million years old, from beneath the sea

Microbes buried beneath the sea floor for more than 100 million years are still alive, a new study reveals. When brought back to the lab and fed, they started to multiply. The microbes are oxygen-loving species that somehow exist on what little of the gas diffuses from the ocean surface deep into the seabed.

The discovery raises the “insane” possibility, as one of the scientists put it, that the microbes have been sitting in the sediment dormant, or at least slowly growing without dividing, for eons.

The new work demonstrates “microbial life is very persistent, and often finds a way to survive,” says Virginia Edgcomb, a microbial ecologist at the Woods Hole Oceanographic Institution who was not involved in the work

UN approves declaration banning all forms of human cloning – UN thông qua tuyên bố cấm mọi hình thức nhân bản vô tính người, năm 2005

UN.org

8 March 2005 –The United Nations General Assembly today approved a non-binding declaration calling on all UN Member States to ban all forms of human cloning, including cloning for medical treatment, as incompatible with human dignity and the protection of human life.

By a vote of 84 in favour, 34 against and 37 abstaining, with 36 absent, the Assembly acted on the recommendation of its Legal, or Sixth, Committee to adopt the text, called the United Nations Declaration on Human Cloning. But some delegates said they opposed banning therapeutic cloning.

The Declaration, negotiated by a Working Group last month, also banned “genetic engineering techniques that may be contrary to human dignity.” It called on States “to prevent the exploitation of women in the application of life sciences” and “to protect adequately human life in the application of life sciences.” Tiếp tục đọc “UN approves declaration banning all forms of human cloning – UN thông qua tuyên bố cấm mọi hình thức nhân bản vô tính người, năm 2005”

Biological research: Rethink biosafety

11 November 2015

Tim Trevan calls on those working with organisms that are hazardous, or could be so, to take lessons from the nuclear industries, hospitals and other sectors that have established a safety culture.

Nature – Two months ago, the US Department of Defense froze operations at nine biodefence laboratories where work is done on dangerous pathogens. Inspectors had discovered live anthrax outside a containment area at the US Army’s Dugway Proving Ground — a facility in Utah that tests defence systems against biological and chemical weapons.
