A startup is employing machine learning to identify what it calls the "dark matter of nutrition."
Why it matters: More than 99% of phytonutrients — the natural chemicals produced by plants — are unknown to science. If we can illuminate that dark matter, we can identify and cultivate compounds in foods for specific health value.
A recent study found countries with certain international travel restrictions have suffered fewer COVID-19 deaths.
Why it matters: Before the novel coronavirus, most experts believed border closures weren't effective in slowing the spread of a pandemic. But it's become clear that addressing how people move is key to controlling a disease, even if closures come with serious costs.
The White House each year welcomes waves of trick-or-treaters, but festivities for the end of this October will adapt to the spookiest thing of all: COVID-19.

An announcement notes that all persons over 2-years-old will be "required to wear a face covering and practice social distancing during their visit to the White House complex."

The nation on Saturday tracked "13,628 new cases and 179 new deaths — a record number of deaths in one day since the start of pandemic," AP reports.
From high levels of obesity and opioid addiction to inequities in access to care, America's pre-existing conditionsmake the country an easy target for COVID-19, as well as future pandemics that could cripple the United States for decades to come.
Why it matters: One of the best ways the country could prepare for future threats — and boost its economy — is to improve Americans' overall health.
The U.S. confirmed at least 83,010 coronavirus cases on Friday, the country's highest daily total since the pandemic started, according to data from the COVID Tracking Project.
By the numbers: Friday's total surpassed the U.S.'s previous record set on July 17 when 76,842 cases were recorded.
Thousands of protesters turned out on Friday in cities across Poland following a Thursday court ruling banning almost all abortions, the BBC reports.
Why it matters: Opinion polls show a "clear majority" against further restricting abortions in the country, per BBC. Poland, a Roman Catholic country, was already said to have one of the strictest abortion laws in Europe.
AstraZeneca announced on Friday that the Food and Drug Administration has authorized the company to restart phase 3 clinical trials for its coronavirus vaccine, which were paused in early September.
Why it matters: All clinical trials were temporarily halted in September after a volunteer became ill with transverse myelitis upon receiving a second dose of the vaccine.
President Trump has not attended a White House coronavirus task force meeting in “several months,” NIAID director Anthony Fauci told MSNBC on Friday.
Why it matters: At the beginning of the pandemic, the task force, led by Vice President Mike Pence, met every day, but in the "last several weeks," members have held virtual meetings once a week, Fauci said, even as the number of new cases continues to surge in the country.
Nearly 130,000 fewer people will die of COVID-19 this winter if 95% of Americans wear face masks in public, according to research published Friday.

A new AI model is able to predict future onset of Alzheimer's disease around 7 years in advance of diagnosis using short speech tests, according to a new study published in The Lancet eClinicalMedicine.
The big picture: There's still no treatment for Alzheimer's, meaning that there could be limited real-world demand by patients for such a tool today. But it could also be valuable for recruiting patients for clinical trials for potential treatments.
"He's a very confused guy," Joe Biden said during the final presidential debate on Thursday after President Trump cited Sen. Bernie Sanders' attempt to make single-payer health care work in Vermont. "He thinks he's running against somebody else"
Why it matters: The Trump campaign has sought to paint Biden as an empty vessel for radical socialism, despite the former vice president's more moderate positions compared to candidates he ran against in the Democratic primary. Biden said the public health insurance option in his plan is not an example of socialized medicine, but is meant to ensure that Americans "have the right to have affordable health care."
President Trump repeated baseless claims at the final presidential debate that the coronavirus "will go away" and that the U.S. is "rounding the turn," while Joe Biden argued that any president that has allowed 220,000 Americans to die on his watch should not be re-elected.
Why it matters: The U.S. is now averaging about 59,000 new coronavirus infections a day, and added another 73,000 cases on Thursday, according to the Covid Tracking Project. The country recorded 1,038 deaths due to the virus Thursday, the highest since late September.
