Common chemical reactions accelerate Brownian diffusion by sending long-range ripples into the surrounding solvent, which would mean that molecular diffusion and chemical reaction are related. Yet that would violate a central dogma of chemistry; that molecular diffusion and chemical reaction are decoupled. 

The ripples generated by chemical reactions, especially when catalyzed - accelerated by substances not themselves consumed - propagate long-range. This challenges the view that molecular motion and chemical reaction reactions affect only the nearby vicinity. 

Johnson  &  Johnson's Ad26.COV2.S COVID-19 vaccine raised neutralizing antibodies and robustly protected rhesus macaques against SARS-CoV-2, the virus that causes COVID-19.

TP53 is a gene found in every cell. It produces a protein called p53 which acts as a cell's barrier, even suppressing genetic mutations in the cell. However, if p53 becomes damaged, it no longer protects the cell as well. Perhaps even the opposite, it may drive the cancer, helping tumors spread and grow. That may be why only 2 percent of such cancers take root in the small intestine, while 98 percent take place in the colon, even though the colon is a much smaller organ.

Biologists have mapped the genome of phylloxera, an aphid-like pest capable of decimating vineyards. In so doing, they have identified nearly 3,000 genes enabling the insect to colonize and feed on grape vines by creating what are essentially nutritionally enhanced tumors.

There will never be another large telescope built in the United States, due to the influence of environmental activists, so those high-paying multicultural white collar jobs are instead going to Chile. But if we want even better conditions. Dome Angus, the highest ice dome on the Antarctic Plateau near the centre of East Antartica, is where to be, finds an analysis.

The problem is that, unlike Chile, no one wants to live there. That's due to the conditions that make it great for a telescope; high altitude, low temperature, and long periods of continuous darkness.

If you've run out of friends to give your sourdought Friendship bread to, and 'feeding' it every three days has become drudgery, you can mix things up a little during your COVID-19 baking spree by making bread the Romans made 2,000 years ago.

How do we know the recipe is real? Because during excavations of Herculaneum in 1930, a loaf of bread was discovered still inside an oven.
