The year that was: major events in 2007
Nature`s Daniel Cressey listed several events as among the most newsworthy in 2007. Some of these events are discussed below.
Biotechnology
November was a good month for biotechnology. American and Japanese researchers derived pleuripotent stem cells from human skin. American researchers also finally succeeded cloning primate embryos in the same month. Both events are major breakthroughs in stem cell research.
This year, two big names in genomics - James Watson and Craig Venter – had their full genome sequenced. In the meantime, American start ups are offering personalized genetic information service (see October post).
Climate Change
The Intergovernmental Panel on Climate Change (IPCC) was co-winner of the Nobel Prize for Peace. In the meantime, the Northwest Passage that connects Atlantic and Pacific Oceans was practical ice-free and passable – a record low in the arctic ice cover. If the IPCC reports and this ice shrinkage do not convince people of the reality of global change, nothing ever will.
Pharmaceutical scandals
China’s former head of food and drug regulatory agency was executed in July after having been convicted of corruption. In the USA, the Avandia scandal rages on. The USA FDA required an additional black box warning for the diabetes medication Avandia (rosiglitazone) labelling last year but Avandia`s troubles didn’t stop there. The latest involved a US senate inquiry and a leak by an NEJM reviewer.
Safety issues
The July earthquake in Japan caused a leak in a major nuclear reactor, reawakening concerns over nuclear energy safety in general.
Two incidences of major biosecurity lapses were reported this year. In the UK, a leaky pipe caused an outbreak of foot-and-mouth disease. In a bioweapons research lab at the Texas A&M University, researchers were exposed to biohazards.
Space technology
Japan and China launched moon probes in 2007 though there were doubts whether China’s claims of success were authentic. China also tested a space weapon by shooting at one of its defunct satellites, scattering potentially dangerous debris in space.
Wired magazine considered the following as the top 10 scientific breakthrough of 2007:
