Gene transfer, a new mechanism
Thought that genetic modification (gene transfer) was artificial? Just done by human researchers? New research now reveals that gene transfer is quite a common event even among higher plants. And even among species quite far apart. Particularly among species that form rhizomes – creeping rootstalks that develop underground and grow horizontally. Like on many grasses.
Pitfalls in nuclear energy risk analysis
Ten years ago, last month, a tsunami struck the West coast of Japan. It flooded the Fukushima nuclear reactor. This resulted in a partial meltdown and a hydrogen explosion, that released a lot of radioactivity. The media devoted many articles to this anniversary. The Conversation raised the question: in hindsight, were events really as bad
Who are we? The microbiome revisted
In the column ‘There is no such thing as an individual’ we mentioned the influence of the microorganisms in our bodies on our development. But biologists have already gone much further along this path. Our microbiome, the living guests in our bodies, number in the millions; among them bacteria, moulds and phages (although phages cannot
Nebulised interferon as a COVID-19 medicine
In a small clinical study conducted in April and May 2020, British scientists investigated the effect of inhalation of nebulised interferon-beta-1a (SNG001) on the development of COVID-19 in patients. The results are encouraging and justify further research. Lung infections Being a 71-year-old asthmatic man, I have to take great care not to run into a
A strategy to reduce animal tests
Animal tests are a controversial issue. On the one hand, many people object to actions that deliberately damage animal welfare. On the other hand, we need these tests in order to establish the safety of medicines and new materials; people demand such safety. But new scientific discoveries might turn the tide. In the Netherlands, the
Pandemics: prevention is better than cure
Our lifestyle greatly promotes the outbreak of pandemics like Covid-19, and this could have devastating consequences. Unless we take action. Says a new report by IPBES, the Intergovernmental Platform on Biodiversity and Ecosystem Services. Policy measures are required. An era of pandemics Pandemics are a modern phenomenon. Large trade networks facilitate a rapid diffusion of
There is no such thing as an individual
Modern biologists are waging a fierce debate on the meaning of the concept of the individual. Definitions of well-known phenomena like symbiosis and parasitism need to be rephrased. The debate goes beyond the world of plants and micro-organisms; the subject of the discussion includes mammals and therefore also mankind. We know for a long time
Bioweapons and super soldiers, genetic technology for warfare
The Conversation recently devoted attention to the opportunities of genetic technology for warfare. Sure, there are international agreements overseeing (and restricting) such opportunities. But technology evolves all the time. Nations tend to explore the edges of what’s allowed, so we need to update the agreements. International agreements The UN Biological Weapons Convention oversees the opportunities
