Men who live alone and have a smaller social network are less likely to be obese than women who have the same lifestyle, according to results found in the Canadian Longitudinal Study on Aging survey. This debunks the cultural trope that marriage is worse for women and better for men when it comes to health.

The data used were the social ties of 28,238 adults aged 45 to 85 and their waist circumference, body mass index and general obesity. These results are only exploratory, they cannot create a causal link and since they are based on surveys have numerous confounders.

Right now, we can play video games and feel like we are 'in the game' but it's still a lot of suspension of disbelief. If you can only see 40 degrees while driving a car in a game that's nowhere close to your peripheral vision in the real world.

Next generation gaming, beyond better graphics, requires establishing new relationships between game progress and entertainment experience. Chess is a much different experience versus another person than it is a computer, as is Poker. Many less experienced people play far more conservatively versus people because computers don't feel real. And then there are some sports where the experience is limited because you aren't very good at them, such as sports.

As of late we have been scratching the barrel of "straightforward" measurements of the properties of the Higgs boson, the particle discovered in 2012 by the Large Hadron Collider ATLAS and CMS experiments. But the one property determined in the measurement published yesterday by the CMS experiment was one that many of us were very interested to check.

If a particle is an elementary body, how many individual, distinct properties can it really have? For the word "elementary" means that it is intrinsically simple! But things are not so clear-cut in the subnuclear world. An elementary particle, while devoid of inner structure and dimensions, still has a number of measurable attributes. For the Higgs boson we may size up:

- mass (of course!)

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.

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.
