From conventional methods of looking after your grain? well, traditionally, you would need a farmer to physically walk on top of the grain bulk with a heavy spear and taking samples at a few points, which is dangerous and in some situations not possible to do. ok, that sounds like a biggerjob. so do you think farmers are going to use this? right now, were focused mostly on centralised grain storage hubs, which are usually owned by grain merchants and port operators, but wed like to develop in th...

Report. now the study was published in a medical journal against this backdrop with the omicron variant going crazy, as you know. it now accounts for 99% of all of the samples that were tested in the u.s. they dont test every single sample that comes from, you know, someone who has covid, but of the ones that they tested, 99% omicron. john? >> just a remarkable number. elizabeth cohen, thanks so much. lets get perspective and insight from dr. liena wen, the former city of baltimore health commis...

More red blood cells are destroyed in space than on earth. dr guy trudel from the ottawa hospital research institute explains. we suspected something happened in the very first days in space, up to ten days. but we found that the destruction continued on for the entire duration of the six—month mission of these astronauts. and this high rate of destruction is not sustainable. so we found also robust signs of an increased production of red blood cells to match the destruction. so unsuspected to...

Yesterday. here is what he had to say about the flood they are seeing. >> two, three weeks ago across the board, we were collecting about 25, 30 covid tests per day. today we finished our day with 20,000 samples collected across the nation. were seeing sampling increases of 300% in florida, texas seeing 400%, southern california seeing 350% increases from last week alone. so definitely seeing a big increase in sample volume. >> so what were seeing here, katy, is definitely a sort of structural f...

>> the true cross is the most important relic. to have it tested in this way could reveal the story potentially true is fascinating. >> this is the first time we actually have direct data of the true cross. >> it involves a series of stages. first of which is to preclean and pretreat the samples and remove any thing that ultimately results -- >> the final stage of the process, enables us to measure particles of carbon 14. the less radio carbon -- we can

Was introduced in the 1990s, detectives were hopeful. it was compared to all of the people that had dna held on that national database, but there was no match. the first of this months reconstructions tells the story of a 25—year—old woman who lived alone in a bedsit at tunbridge wells in kent. and tunbridge wells. the team tried asking for help on the bbc�*s crimewatch programme, which was to feature the tunbridge wells murders twice over the years. we had samples from the scene. we had t...
