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.

Reliable estimates of the mortality from SARS-CoV-2 infection are essential to understanding the COVID-19 epidemic and develop public health interventions, but we don't have them. If you realistically think that China, where the disease originated, only had a relative few deaths while, Brazil, which is both crowded and lacking in health infrastructure, has a fraction of U.S. deaths, you don't understand how disease transmission works.

But you should understand how numbers can be manipulated. There is also conspiracy theory that political activists are exaggerating or underestimating the disease in an election year.

Kids often have excitement or anxiety about the return to school. COVID-19 threw a lot of families into disarray when kids started staying home. And it be may present as they go back. School safety protocols for COVID-19 or other things highlighted in the news such as racial tension could cause increases in anxiety.

While a little anxiety is normal, it may that the usual relief found in positive student relationships may disappear along with bullying if kids are again staying home.

Here are some tips for navigating the adjustment if kids are going back to school.
