In contrast to the energy balance model, the carbohydrate-insulin model makes a bold claim: overeating isn’t the main cause of obesity. Instead, the carbohydrate-insulin model lays much of the blame for the current obesity epidemic on modern dietary patterns characterized by excessive consumption of foods with a high glycemic load: in particular, processed, rapidly digestible carbohydrates. These foods cause hormonal responses that fundamentally change our metabolism, driving fat storage, weight gain, and obesity.

Perspective published in The American Journal of Clinical Nutrition argues the root causes of the obesity epidemic are more related to what we eat rather than how much we eat.

Statistics from the Centers for Disease Control and Prevention (CDC) show that obesity affects more than 40% of American adults, placing them at higher risk for heart disease, stroke, type 2 diabetes, and certain types of cancer. The USDA’s Dietary Guidelines for Americans 2020 – 2025 further tells us that losing weight “requires adults to reduce the number of calories they get from foods and beverages and increase the amount expended through physical activity.”

Pollution creates particulate matter (tiny floating particles) and aerosols that can be harmful to our health. With missions like the Multi-Angle Imager for Aerosols (MAIA), public health officials can start to map this particulate matter around the world, understand its effect on diseases, and know where the most risk is. In this month’s talk, we’ll chat with the instrument operations systems engineer for MAIA and discuss how vital positions like hers are for mission success and for making sure important data gets back to us on Earth.

Automation will drag on at the normal pace. 2025 i think will be the key year, where Human Level hands could turn up on the humanoid robots, and an early phase of Human Level AI turns up; if those 2 things happen automation of jobs will really start to move fast.

Ask for a roast beef sandwich at an Arby’s drive-thru east of Los Angeles and you may be talking to Tori — an artificially intelligent voice assistant that will take your order and send it to the line cooks.

“It doesn’t call sick,” says Amir Siddiqi, whose family installed the AI voice at its Arby’s franchise this year in Ontario, California. “It doesn’t get corona. And the reliability of it is great.”

Israeli scientists are harnessing the “destructive” qualities of allergy-causing cells, as part of a bold attempt to pioneer a new immunotherapy for fighting cancer. A research team from Tel Aviv University has found that eosinophils, white blood cells that induce allergies, significantly reduce the growth of human tumors in vitro, and mouse tumors in the body. Nine days after mice were injected with eosinophils, the overall size of tumors per mouse averaged half that of mice who weren’t injected.

Tumors in mice lost half their size when injected with eosinophils, best known for inducing allergies; promising results also seen in human tumor cells in vitro.

The NHS has launched the world’s largest trial of a potentially gamechanging blood test that aims to detect more than 50 types of cancer before symptoms appear.

More than 100,000 volunteers are being sought to provide blood samples at mobile test clinics in regions across England from Monday to assess how well the test works in the health service.

More treatments are available for Covid-19 as hospitalizations spike, but some drugs are sitting on the shelves unused.

As record daily Covid-19 hospitalizations and deaths this month in the US have pushed the pandemic to new crisis levels, senior government health officials have lamented that many patients are not getting the drugs — including monoclonal antibodies, antivirals, and corticosteroids — available to treat the disease, leaving many doses unused.

“Even with a vaccine, we know we will not prevent every infection,” said US Surgeon General Jerome Adams on January 14 during a press conference. “So today we want to remind everyone that for those of you who do contract Covid, we have excellent treatments to keep you out of the hospital, to keep you out of the ICU, to help you recover quickly.”

Scientists will soon have the tools to rewrite the book of life, and in doing so, edit out sections that cause disease, piece by piece. But is the technology safe and will all of us get the benefits, or will it be the preserve of those who can afford it?

“Identification of these compounds means that we are one step closer to being able to molecularly diagnose dementia,” said senior author of the study, Professor Mitsuhiro Yanagida, who leads the G0 Cell Unit at OIST.

Summary: Researchers identified 33 metabolic compounds in blood samples that differed between those with dementia and cognitively healthy older adults. 7 of the metabolites were elevated in dementia patients, while 26 were at lower levels compared to samples of those without dementia. Elevating levels of those metabolites could have a neuroprotective effect against dementia.
