“just as tusks evolved because they provide a number of benefits, a striking new study shows that some populations of African elephants have rapidly evolved to become tusk–less. Published in the journal Science, the paper’s authors found that many elephants in a park in Mozambique, which were heavily hunted for their ivory during a civil war a few decades ago, have lost their tusks — presumably because tuskless elephants are more likely to survive and pass the trait on to their offspring.”
…
“In theory, it’s advantageous to be born without tusks in areas where poachers are active, Hendry said. But tusklessness also has its downsides. Elephants need their tusks to dig, lift objects, and defend themselves. The hulking incisors are not useless appendages.
The genes that seem to make female elephants tuskless also appear to prevent mothers from giving birth to male calves — that’s why all the tuskless elephants in the park are female, Pringle said. (Some mothers did give birth to males with tusks, who likely didn’t inherit the gene.) Over time, a shift in the sex of elephants could have consequences for population growth.
There are also potential costs to African grasslands, which are among the rarest and most biodiverse ecosystems on Earth, the study authors write. By turning over soil in search of food and minerals and gouging trees with their tusks, African savanna elephants prevent forests from growing too dense and help maintain grasslands. That’s why they’re considered “engineers” of the ecosystem. If they lose their tusks, a whole web of plants and animals may feel the impact.
“This evolutionary change could have massive cascading ecological influences,” Hendry said.”
“Companies across the United States can’t find enough employees. One immediate solution is simple: Bring in more foreign workers.
The US needs roughly 10 million people, including low-wage and high-skilled workers, to fill job openings nationwide — and only 8.4 million Americans are actively seeking work.
And despite job openings hitting historic highs in July and extended unemployment benefits ending in September, Americans aren’t returning to work, especially in low-wage industries. At the same time, workers are resigning in record numbers. And though consumer spending has surged this year, businesses don’t have the people to meet demand — to cope, some companies are raising their prices. Supply chain bottlenecks are even threatening to ruin Christmas.
When the economy is fragile, there’s an instinct to shut borders to protect American workers. And indeed, that’s what the US has done during the pandemic, practically bringing legal immigration to a halt and closing the southern border to migrants and asylum seekers. In a normal year, the US welcomes roughly 1 million immigrants, and roughly three-quarters of them end up participating in the labor force. In 2020, that number dropped to about 263,000.
Generally, economic research has shown that the arrival of low-wage foreign workers has little to no negative impact on native-born workers’ wages or employment. And under the current circumstances, welcoming more low-wage foreign workers could address acute labor shortages in certain industries, helping hard-hit areas of the country recover while staving off higher inflation.
The industries currently facing the worst labor shortages include construction; transportation and warehousing; accommodation and hospitality; and personal services businesses like salons, dry cleaners, repair services, and undertakers. All four industries had increases in job postings of more than 65 percent when comparing the months of May to July 2019 to the same time period in 2021, according to an analysis conducted for Vox by the pro-immigration New American Economy think tank. Immigrants make up at least 20 percent of the workforce in those industries.”
“For anyone who had followed the trial closely, this outcome is unsurprising. The prosecution simply did not meet its burden of proof, and Rittenhouse’s defense team presented considerable evidence that he reasonably feared for his life each time he pulled the trigger. A witness testified that Joseph Rosenbaum, the first man shot by Rittenhouse, had threatened Rittenhouse’s life and was attempting to wrest control of Rittenhouse’s AR-15. The second man, Anthony Huber, struck Rittenhouse with a skateboard. And the third man—Gaige Grosskreutz, who survived—admitted on the stand that he had first pointed his own gun at Rittenhouse; Rittenhouse shot him in response to this perceived threat. As former Rep. Justin Amash (L–Mich.) put it: “The Rittenhouse case was a clear case of self-defense based on the evidence presented.””
…
“it had little to do with race: Rittenhouse and all three of his victims were white.”
…
“It is not necessary to elevate Rittenhouse to hero status, or to agree with his very poor decision to involve himself in the Kenosha riots, to accept that the prosecution failed to prove the charges against him.”
“After more than two decades in orbit, NASA is preparing to retire the International Space Station. The habitable satellite only has permission to operate until 2024, and while it’s likely that the space station’s funding could be extended until 2028, NASA plans to decommission the ISS and find a replacement by the end of the decade. Cue Jeff Bezos.
The billionaire’s spaceflight company, Blue Origin, has released its proposal for a new, commercial space station called Orbital Reef. With the help of several other companies, including Sierra Space and Boeing, Blue Origin plans to build a satellite that’s slightly smaller than the ISS and houses up to 10 people. The design includes desk space, computers, laboratories, a garden, and 3D printers. The goal, the company says, is to bring the “mixed use business park” concept into orbit and lease out office space to interested parties, including government agencies, researchers, tourism companies, and even movie production crews.”

“NASA doesn’t mind the corporate takeover of low-Earth orbit. The agency’s first space station, SkyLab, was only in orbit for a few months before NASA let the vehicle descend and decompose into the atmosphere. The space agency has been weighing defunding the ISS, which is full of aging hardware, for several years, and has already set aside up to $400 million to fund new, privately built and operated space stations through its Commercial LEO Destinations program. Eventually, NASA hopes that it can send its astronauts to these stations instead of paying to maintain the ISS. Overall, the plan could save the government more than $1 billion every year.”
…
“”Having these commercial space stations will be a way of America keeping their foot in low-Earth orbit while focusing more of their resources on moon and Mars exploration.””
…
“Blue Origin isn’t the only company vying to replace the ISS. About 12 other firms have already sent space station proposals to NASA’s Commercial LEO Destinations program.”
…
“For NASA, it’s also critical that at least one of these companies succeeds, and the agency told Recode it could fund up to four of the proposals. After all, time is running out on the ISS, where malfunctions and outdated technology and equipment are common.”
“If Congress fails to enshrine key climate policies as federal laws, Biden’s Plan B includes executive orders and major regulations from the Environmental Protection Agency, the New York Times reported.
The problem is that executive actions aren’t an ideal substitute for federal laws, and may last only as long as Biden’s presidency. EPA regulation also “tends to lag [behind] the technological realities,” meaning it may only modestly nudge the economy in a new direction, Jesse Jenkins, an environmental engineering professor at Princeton University, told Vox. It’s also vulnerable to intervention by the Supreme Court.”
“More than 580,000 Americans are homeless. The median sale price for a home has just surpassed $400,000. Homeownership is on the decline.
This, by all accounts, is a national emergency — and one House Democrats had proposed $330 billion to tackle as part of their Build Back Better plan. This package was both a once-in-a-generation investment and also barely enough to scratch the surface. Now, even those proposed investments are being cut down as part of negotiations over the final package.”
…
“some in Congress were willing to make substantial investments, very few were willing to tackle the fundamental problem that was making homes so expensive in the first place: lack of supply.
Yes, it’s easier to try to help people afford something expensive than to try and make it less expensive to begin with. But many of the policies that try to subsidize housing can actually make it more expensive. “What you really need if you want to lower those new home prices, is you need to build more homes — and there’s not that much of that in this bill,” says Paul Williams, a fellow at the Jain Family Institute.”
“The Afghan evacuation in August was a shock to the US immigration and resettlement system, a collection of federal programs and nonprofit organizations that had already been upended by the Trump administration. Afghan evacuees are in this holding pattern for several reasons.

“Outside experts have estimated that as much as $75 billion should be spent over 10 years on public health infrastructure, preparedness, and prevention.
The revised Build Back Better legislation totals roughly $10 billion in public health infrastructure and pandemic preparedness funding over the next few years — a down payment on better readiness, in Democrats’ view, but one without assurance of future installations.
“All too often, when there’s a crisis, the reaction is to put money into public health. Once the crisis subsides, the funding tends to dry up,” Ron Bialek, president of the Public Health Foundation, told me. “This is not a recipe for success.””
“Under the Paris agreement, every country is required to publish a climate change target and a route for getting there, or what’s called a Nationally Determined Contribution (NDC). The first round of NDCs put forward in 2015 were clearly inadequate, putting the world on course for roughly 2.7°C of warming by the end of the century.
Climate leaders hoped that in the runup to COP26, countries would roll out new commitments for the coming decade, as well as long-term strategies for eliminating emissions by the middle of the century. As of October 21, 114 countries and the European Union have submitted new NDCs. Some major emitters like the US, United Kingdom, and China have proposed or submitted stronger targets. But others, like Russia, Brazil, and Australia, did not meaningfully ramp up their goals. Still others like India have yet to submit a new NDC.
The leaders at COP26 will try to create carrots and sticks to motivate the laggards and holdouts to take more aggressive action. Many countries are now adamant that the limit for warming this century should be 1.5°C, now that many countries have already suffered the tolls of disasters worsened by climate change — a sign that 2°C of warming would be far worse.”
…
“The core injustice of climate change is that the people who contributed least to the problem stand to suffer the most.”
…
“a key part of the discussion at COP26 will be around how to compensate countries facing the impacts of climate change today, from rising sea levels eroding shores to more devastating extreme weather.”

“The US has the dubious distinction of being the only country to complete a 360-degree turn on the Paris agreement. It helped convene the accord in 2015, yet former President Trump withdrew the US in 2020. President Biden signed an executive order in January to rejoin and the US was formally back in the Paris accord in February.
Since the US is the wealthiest country in the world and the largest historical emitter of greenhouse gases, it plays a prominent role in climate negotiations and has an even greater obligation to act on the crisis. At COP26, the US not only has to make up for lost time, it also has to rebuild trust with other countries and show that it’s willing to be more ambitious.”
