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. 

Tennessee corn, soybean, cotton and wheat producers are estimated to have declines in income of $58.8 million, $21.4 million, $20.3 million and $1.2 million, respectively, for a total decline of $101.7 million - and that's just what is known right now.

Samples of breast milk collected by the Mommy's Milk Human Milk Research Biorepository from women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) only showed one positive for viral RNA. However, subsequent tests found that the virus was unable to replicate, and thus unable to cause infection in the breastfed infant.

There have been no documented cases to-date of an infant contracting COVID-19 as a result of consuming infected breast milk but without studies it was hard to be sure, to this is good news for families with new babies.
