A New Species Of “Bird-Like Dinosaur” Discovered, Preserved In Amber (Video)

A tiny new species of bird-like dinosaur has been discovered, preserved in a lump of 99-million-year-old amber. The tooth-filled skull is only 7.1mm long, suggesting that this ancient creature would have been the size of a hummingbird – far smaller than other dinosaurs known from that time. Unusual features include large, side-facing eyes and a large number of sharp teeth suggesting a predatory lifestyle. The species has been named Oculudentavis khaungraae and is evidence of previously unimagined biodiversity in the Mesozoic era.

Elderly & Coronavirus: Nursing Homes Increase Guest Symptom, Travel And Exposure Reviews

From a Harvard Gazette online article (March 10, 2020):

Harvard Gazette Elderly Coronavirus Risk Article March 10 2020There’s a symptom review, there’s a travel review, and there’s an exposure review. And if the answer to any of those questions is yes, then you’re asked to not come in. And so far people have been compliant and have left. So that is a good thing.

If you have a cough and a fever, if you’ve got respiratory symptoms and you’re short of breath, if you’ve traveled to a place of concern or if you may have been exposed to someone who did — especially if you’re symptomatic — then I would definitely ask, “Do I really need to visit my grandma today? Can I wait and can I Skype her? Can I do FaceTime?”

I know that’s hard for some of our older adults who aren’t technologically savvy, but maybe now is the time to get them hooked up. It really would be heartbreaking if, in wanting to do something positive for someone’s emotional or mental health, you ended up infecting them.

Harvard-affiliated Hebrew SeniorLife offers a continuum of care for 3,000 elderly people daily, with a range of services including residential assisted living, short-term rehabilitation, outpatient services, and long-term care for those with chronic illness. In a Q&A interview aimed at understanding the challenges involved, Harvard Medical School Assistant Professor Helen Chen, Hebrew SeniorLife’s chief medical officer, discussed steps the facility has taken to combat the virus and the outlook going forward.

The Democratic contest has effectively become a two-horse race between Biden and Sanders The former vice president’s victory in Michigan, as well as Missouri and Mississippi, dealt a serious blow to Sanders, who is urgently seeking to jump-start his flagging campaign.

Health Studies: “Spirulina” Improves Cardiovascular (CVD) Risk Factors, Aids In Weight Loss (BMJ)

From a BMJ Open Heart online study (March 8, 2020):

BMJ Open Heart JournalOverall, the evidence in the literature suggests that spirulina improves several well-established CVD risk factors including hyperlipidaemia and seems to provide benefits around weight loss. 

Although caloric restriction and exercise are the mainstay treatments for obesity, spirulina has shown significant benefits in aiding weight loss. The phycocyanin in spirulina contains a light-harvesting chromophore called phycocyanobilin, which is capable of inhibiting nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) oxidase, a significant source of oxidative stress in adipocytes playing a key role in inducing insulin resistance and shifting adipokine and cytokine production in hypertrophied adipocytes. Thus, by suppressing adipocyte oxidative stress, spirulina may lead to systemic anti-inflammatory and insulin-sensitising effects.

BMJ Open Heart Journal Study of Spirulina Health benefits March 2020

Spirulina is both a salt and fresh water blue-green algae, which is being increasingly studied recently. Spirulina was initially classified under the plant kingdom due to its rich plant pigments and its ability to photosynthesize, but was later placed into bacterial kingdom (cyanobacteria) due to its genetic, physiological and biochemical makeup. Spirulina grows naturally in high salt alkaline water reservoirs in subtropical and tropical areas of America, Mexico, Asia and Central Africa.

Studies: “Ultra-Processed Foods” Are 58% Of All Calories In U.S., & Obesity Epidemic’s Major Cause

From a The Guardian online article (Feb 12, 2020):

What characterizes ultra-processed foods is that they are so altered that it can be hard to recognize the underlying ingredients. These are concoctions of concoctions, engineered from ingredients that are already highly refined, such as cheap vegetable oils, flours, whey proteins and sugars, which are then whipped up into something more appetizing with the help of industrial additives such as emulsifiers.

From a MedPage Today online article (March 7, 2020):

The top ultra-processed foods by calorie intake were breads, beverages, cakes, Ultra-Processed Diet and Unprocessed Diet Infographiccookies and pies, salty snacks, frozen and shelf-stable dishes, pizza, and breakfast cereals.

Altogether, ultra-processed foods accounted for 58% of all calories in the U.S. diet and nearly 90% of all added sugars.

They divided foods into four categories:

  • Unprocessed or minimally processed foods: Fresh, dry, or frozen fruits or vegetables, grains, legumes, meat, fish, and milk
  • Processed culinary ingredients: Table sugar, oils, fats, salt, and other substances extracted from foods or from nature and used in kitchens to make culinary preparations
  • Processed foods: Foods manufactured with the addition of salt, sugar, or other substances of culinary use to unprocessed or minimally-processed foods, such as canned food, simple breads, and cheese
  • Ultra-processed foods: Formulations of several ingredients that — besides salt, sugar, oils, and fats — include food substances not used in culinary preparations, in particular, flavors, colors, sweeteners, emulsifiers, and other additives used to imitate sensory qualities of unprocessed or minimally-processed foods and their culinary preparations or to disguise undesirable qualities of the final product
