Bacille Calmette-Guerin (BCG) is an attenuated strain of Mycobacterium bovis that is used widely as a vaccine for tuberculosis and is used as an effective treatment for superficial bladder carcinoma. Despite being the most successful cancer biotherapy, its mechanism of action and response determinants remain obscure.
The hydroxyl radical (OH) plays an important role in middle atmospheric photochemistry, particularly in ozone (O3) chemistry. Because it is mainly produced through photolysis and has a short chemical lifetime, OH is expected to show rapid responses to solar forcing [e.g., the 11-y solar cycle (SC)], resulting in variabilities in...
Certain bacterial enzymes, the diiron hydrogenases, have turnover numbers for hydrogen production from water as large as 104/s. Their much smaller common active site, composed of earth-abundant materials, has a structure that is an attractive starting point for the design of a practical catalyst for electrocatalytic or solar photocatalytic hydrogen...
The latest addition of peer-reviewed data archived to our database of marine organism responses to atmospheric CO2 enrichment is Foraminifera [Amphistegina radiata].
The precipitate crash in summer arctic sea ice that we are now witnessing is a momentous and awesome event, the consequences of which are enormous and terrifying. (see the other posts on this page)
To bear witness to this and communicate its significance to others you could organise an "Arctic Vigil" in your own town or area.
This was originally the idea of Kirklees...
