Researchers say a rare type of meteor recovered nearly three years ago from a frozen lake in the U.S. state of Michigan has offered one of the best glimpses yet into the organic compounds such objects carry.A study published in the journal Meteoritics & Planetary Science tells the story of a bright meteor, also known as fireballs for how they light up the night sky, that fell in January 2018.Researchers say the meteors that shine with such brightness are usually larger and have traveled farther into Earth’s atmosphere without breaking up, raising hopes pieces could be recovered. Using weather radar, they were able to track the meteor’s trajectory, discovering large pieces just two days after it hit a frozen lake.University of Chicago researcher Philipp Heck said finding the meteorite (what a meteor is called once it lands on Earth) pieces so quickly and on a frozen lake was significant. He said meteors often fall into dirt or water, and if they are not discovered quickly, they can be contaminated by organic Earth material.The researchers determined they’d found an “H4 chondrite” meteorite. Only 4% of all meteorites falling to Earth are of this type, at least in recent history. Heck said it had “a rich inventory of extraterrestrial organic compounds,” which contain carbon, one of the basic ingredients of life on Earth.The discovery adds evidence to the widely held theory that compounds such as these — the so-called building blocks of life — were delivered to Earth by similar meteors shortly after Earth formed.Heck said the discovery of the Michigan meteor and subsequent analysis also helped scientists develop new analytical techniques to study meteors of its kind and gain knowledge that can be shared with other scientists around the world.

A rising tide of new coronavirus cases worldwide is forcing leaders to consider new lockdown measures to contain an increase in infections.
British Foreign Minister Dominic Raab said in an interview with BBC television Friday a national lockdown in his country is not inevitable to prevent the further spread of the disease, adding that a localized approach would be efficient if rules for each area were strictly observed.
Raab’s statment followed announcements by leaders of France and Germany earlier in the week to impose new lockdowns.
French President Emmanuel Macron announced a nationwide monthlong lockdown that will take effect Friday. Macron said restaurants, bars, cafes and other nonessential businesses will be closed, while citizens will only be allowed to leave their homes for work, shopping and doctor appointments.

(Photo/Markus Schreiber)German Chancellor Angela Merkel announced a set of similar measures in her own month-long lockdown which takes effect Monday. In addition to restaurants and bars, all gyms, theaters and opera houses will be shut down under Merkel’s order, while the majority of businesses, shops and hair salons will be allowed to remain open.
Schools in both nations will remain open during their respective lockdowns.
The restrictions were announced by Macron and Merkel as both nations struggle with a record number of new COVID-19 cases practically every day.
France and Germany joined several other European nations that have been forced to impose a new set of restrictions to deal with a second and growing wave of the virus as the cold weather season approaches in the Northern Hemisphere.
Ukraine reported Friday a record 8,312 new COVID-19 cases in the previous 24 hours, up from the October 23 high of 7,517, with total infections at 378,729. The deaths also jumped by a record 173, for a toll of 7,041.
In Japan, the health ministry said Friday that the coronavirus cases topped 100,000, nine months after the first case was reported in mid-January. Japan has more than 1,700 deaths.
As of early Friday, there are more than 45 million total COVID-19 cases worldwide, including over 1.18 million deaths. India has reached the milestone of over 8 million total novel coronavirus cases, second only to the United States, with 8.94 million total confirmed cases.
As the effort to develop a safe and effective vaccine continues, U.S. President Donald Trump’s administration said it would ensure that everyone in the United States will be able to be inoculated free of charge.

Ecological destruction and unsustainable consumption have entered humanity into an “era of pandemics,” according to a new report.”Without preventative strategies, pandemics will emerge more often, spread more rapidly, kill more people, and affect the global economy with more devastating impact than ever before,” says the report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, a global expert body advising governments.The authors say roughly $50 billion per year in pandemic prevention would spare the world about $1 trillion per year on average in economic damage, not to mention the toll in human suffering.The report suggests ways to shift the focus to prevention, rather than trying to contain pandemics after they happen.SpilloverAs of July, COVID-19’s economic toll was at least $8 trillion and counting, the authors say.It’s just the latest costly emerging infectious disease, following HIV/AIDS, SARS, Ebola, Zika, H1N1 swine flu and others.All of these deadly diseases originated in animals before “spilling over” into humans. Nearly three-quarters of all emerging diseases have animal origins. And there are hundreds of thousands more possibly infectious viruses that have not been discovered yet, the report notes.But don’t blame the animals. The rate of spillover has increased because of human activities.COVID-19 is a prime example of the problem, the authors say. The coronavirus that causes the disease likely emerged from bats in China, where expanding human populations are increasingly encroaching on wildlife habitat. It probably spread through the wildlife trade, at a market where vendors sell wild animals for food and medicine.Deforestation, agricultural expansion, urbanization and other land-use changes are responsible for about a third of all new diseases to emerge since 1960, the report says. The $100 billion-plus global wildlife trade is also responsible for the spread of new and existing diseases and is a threat to biodiversity.Not too lateHowever, “this is not a doom and gloom report saying the world’s going to end and it’s too late,” said report author Peter Daszak, president of EcoHealth Alliance, a global health, conservation and development organization. “This is an optimistic call for action.”The current strategy to deal with pandemics is to wait for them to emerge and try to identify them before they spread, Daszak said.COVID-19 has demonstrated the flaws in that plan. Chinese authorities tried to contain it after the disease emerged late last year, but it was too late.”And here we are waiting for a vaccine and drugs to work,” Daszak said. “It’s not a good strategy. We need to do more.”The report calls for “transformative change towards preventing pandemics.”Some of that change needs to come from consumers.One change involves eating meat.Demand for meat drives increased pandemic risk in two ways, the report says. Feeding food animals is a major driver of deforestation. Also, intensive animal agriculture, which packs many animals into small spaces, often in close proximity to people, makes it easy for germs to jump species.”We can continue to eat meat,” Daszak said, “but we need to do it in a way that is far more sustainable if we want to get rid of pandemics.”The report suggests taxes on meat or livestock or other ways to incorporate the costs of pandemics into the price of production and consumption.Consumers also can drive change by pressuring companies to reduce deforestation, for example.”Global for-profit companies care about what we, the public, think about them,” Daszak said. “They respond when people call them out.”Government policy should focus on pandemic prevention as well, the authors say.Emerging-disease risk should be factored into any large-scale land use planning. Wildlife trade enforcement should focus on reducing or removing species at high risk of spreading diseases. And increased disease monitoring should focus on the links between human health, animal health and the environment, known as the One Health approach.All these suggestions, he noted, are “easy to say, really difficult to do.”These measures and others would cost about $40 billion to $58 billion per year, the report says.But with the bill for pandemics averaging a trillion dollars per year, Daszak said, “an ounce of prevention is worth a hundred pounds of cure.”

The White House Coronavirus Task Force warned Thursday of an “unrelenting” spread of the virus, particularly across the western half of the country, Reuters reported. Members of the task force are reportedly pushing for aggressive measures to quell the spread of the virus.The United States has confirmed more than 8.9 million cases of COVID-19 and recorded more than 228,000 deaths as of Thursday, according to data from the Johns Hopkins University Coronavirus Resource Center.”We continue to see unrelenting, broad community spread in the Midwest, Upper Midwest and West. This will require aggressive mitigation to control both the silent, asymptomatic spread and symptomatic spread,” said the task force’s report to one state, according to CNN. The task force’s most prominent member, Dr. Anthony Fauci, told CNBC Wednesday that the coronavirus outbreak in the U.S. is “going in the wrong direction.” “If things do not change, if they continue on the course we’re on, there’s going to be a whole lot of pain in this country with regard to additional cases and hospitalizations, and deaths,” Fauci said, noting that case numbers were rising in 47 states.At least seven states reported record one-day case increases Thursday, according to Reuters.
