Historically, lung cancer incidence rates have been higher in Black people than White people among men of all ages and among younger women, likely reflecting historically higher smoking rates in Black adults.

That is no longer the case, and in women the trend has even reversed.

That is a big win for science and health nonprofit groups like ours, which have warned about the perils of smoking for our entire existence.

The majority of today's plant-based food was created using scientific optimization of traits - genetic engineering. Watermelons, bananas, tomatoes, lettuce, and corn are all great examples of genetically engineered foods that few realize are not natural even if they carry an "organic" manufacturing process sticker.

Despite that success, government-funded scientists are reporting less funding than ever and the reason is largely because the private sector has done so well. It may also be because the war against agriculture is being waged by those often in the same political tribe as those who want to pursue a career in academia. No one wants to be shamed at parties because they do science that a giant chunk of people educated by marketing dislike.

If you or someone you know have gotten a cancer diagnosis, you know one of the first tests is to see if it has spread to your lymph nodes.

That is because they will often be a harbinger of spread to distant organs. Most cancer deaths happen after cancer spreads to other parts of the body through a process known as metastasis. This occurs when cancer cells from the primary tumor spread through blood vessels or migrate through lymphatic vessels before entering the blood.

Are smiles, scowls, or sympathetic sighs universal across cultures? Studies from Namibia to Bhutan have attempted to find out, but the findings have been too inconsistent to take seriously.

It may be because asking asking participants in a remote culture to match depictions of Western facial, bodily, or vocal expressions to situations or words in their native language is not the way to go.

Fear of thunder or other loud noises, nervousness about new areas, and fear of slippery surfaces and heights are common among dogs but a new paper says these non-social fears can be mitigated.

Not for all dogs, the typical Cairn Terrier will remain more fearful than the average Chinese Crested Dog, but living environment and lifestyle will help.

What works, according to 14,000 dog owners surveyed? Exposure to new things as puppies. Insufficient socialization of puppies to various situations and new environments were a link with fearfulness related to novel situations, loud noises as well as different walking surfaces. The company of other dogs reduced the occurrence of non-social fear.

Data from 737,839 people with dementia find that 73.5 percent of them filled at least one prescription for an antidepressant, opioid painkiller, epilepsy drug, anxiety medication or antipsychotic drug in a one-year period. 

The percentages generally were even higher among women, non-Hispanic white patients, people in their late 60s and early 70s, and people with low incomes.

The problem; there is no evidence they work, they are not approved for off-label use in dementia, and some of the drugs have been linked to worse cognitive symptoms in old adults.
