(Cell Press) In a study appearing April 30 in the journal Current Biology, scientists tell the story of three 16th century African slaves identified from a mass burial site in Mexico City. Using a combination of genetic, osteological, and isotope analyses, the scientists determined from where in Africa they were likely captured, the physical hardships they experienced as slaves, and what novel pathogens they may have carried with them across the Atlantic.

(University of Maryland) Many historians have claimed the Justinianic Plague (c. 541-750 CE) killed half of the population of Byzantine (Eastern Roman) Empire. New historical research and mathematical modeling challenge the death rate and severity of this first plague pandemic, named for Emperor Justinian I.

(Universitat Pompeu Fabra - Barcelona) Expansions by groups of humans were common during prehistoric times, after the adoption of agriculture. Among other factors, this is due to population growth of farmers which was greater than of that hunter-gatherers. We can find one example of this during the Neolithic period, when farming was introduced to Europe by migrations from the Middle East.

(Perot Museum of Nature and Science) Published in PLOS ONE today, a study by an international team from the Perot Museum of Nature and Science in Dallas and Hokkaido University in Japan further explores the proliferation of the most commonly occurring duck-billed dinosaur of the ancient Arctic as the genus Edmontosaurus. The findings reinforce that the hadrosaurs -- dubbed 'caribou of the Cretaceous' -- had a geographical distribution of approximately 60 degrees of latitude, spanning the North American West from Alaska to Colorado.

(University of Warwick) A microbial community is a complex, dynamic system composed of hundreds of species and their interactions, they are found in oceans, soil, animal guts and plant roots. Each system feeds the Earth's ecosystem and their own growth, as they each have their own metabolism that underpin biogeochemical cycles. Researchers from the School of Life Sciences at the University of Warwick have produced an extendable thermodynamic model for simulating the dynamics of microbial communities.

(University of Bonn) The extent to which Brazilian soy production and trade contribute to climate change depends largely on the location where soybeans are grown. This is shown by a recent study conducted by the University of Bonn together with partners from Spain, Belgium and Sweden. In some municipalities, CO2 emissions resulting from the export of soybean and derivatives are more than 200 times higher than in others.

(University of Tsukuba) Researchers from the University of Tsukuba have revealed that pectin, a carbohydrate found in plant cell walls, plays a vital part in the development of female reproductive tissues of rice plants. It was found that the presence of a gene involved in pectin modification increased plant fertility relative to a modified plant with the gene removed. These findings could have major implications in crop variety development and genetic modification.

(Smithsonian Tropical Research Institute) Oil pollution is known to cause lethal and sublethal responses on coral communities in the short-term, but its long-term effects have not been widely studied. The Bahia Las Minas oil spill, which contaminated about 40 square kilometers (about 15 square miles) near the Smithsonian's Galeta Point Marine Laboratory in Colon and became the largest recorded near coastal habitats in Panama, served as an opportunity to understand how coral reefs in tropical ecosystems recover from acute contamination over time.

(American Chemical Society) When a dead body is found, one of the first things a forensic pathologist tries to do is estimate the time of death. There are several ways to do this, including measuring body temperature or observing insect activity, but these methods don't always work for corpses found in water. Now, researchers are reporting a mouse study in ACS' Journal of Proteome Research showing that certain proteins in bones could be used for this determination.

(American Association for the Advancement of Science) Microplastic particles entering the sea surface were thought to settle to the seafloor directly below them, but now, a new study reveals that slow-moving currents near the bottom of the ocean direct the flow of plastics, creating microplastic hotpots in sediments of the deep sea.

(University of Colorado at Boulder) CU Boulder researchers have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected by ocean acidification to adapt to changing conditions in real time, improving economic and food security in the next few decades.

Palestinian officials said Friday that Israel is forcing banks in the occupied West Bank to close accounts held by the families of prisoners in Israeli jails to prevent the Palestinian Authority from providing stipends to them. Israel has long objected to the Palestinian Authority's payments to the families of prisoners and those killed in the conflict, including militants, saying it rewards terrorism. The Palestinians view the payments as a social safety net for those living under decades of military occupation.

The presumptive Democratic presidential nominee Joe Biden campaigns virtually in his Delaware home; Fox News correspondent Peter Doocy reports.

Chief Justice Patience Roggensack faced backlash for her comment, with some people calling it "elitist" to separate meatpackers from "regular folks."

Mikheil Saakashvili, the former president of Georgia, vowed on Friday to help his new boss, Ukrainian President Volodymyr Zelenskiy, clean out a political "swamp" of oligarchs' interests that he said were preventing Ukraine prospering. Twice president of Georgia, Saakashvili had a brief but stormy spell in Ukrainian politics five years ago under Zelenskiy's predecessor Petro Poroshenko in which he once clambered onto a roof to avoid law enforcement.

There aren’t a ton of synonyms for the word “hypocrisy.” I’ve become aware of this problem ever since I began writing about the Tara Reade–Joe Biden situation. I keep gravitating towards phrases such as “despicable hypocrisy,” or “partisan hypocrisy,” or “unconscionable hypocrisy,” but you can only go to the well so often. Really, though, I’m not sure how else to describe the actions of someone like Senator Dianne Feinstein.You might recall that it was Feinstein, the ranking member of the Judiciary Committee, who withheld Christine Blasey Ford's allegation of sexual misconduct against Supreme Court nominee Brett Kavanaugh from the Senate so that it could not be properly vetted, in a last-ditch effort to sink the nomination.Feinstein knew that Ford's credibility was brittle -- the alleged victim could not tell us where or when the attack occurred, hadn’t mentioned Kavanugh’s name to anyone for over 30 years, and offered nothing approaching a contemporaneous witness.At first, Feinstein did not want to provide Ford’s name, or a place or time of the alleged attack, or allow the accused to see any evidence against him, denying him the ability to answer the charges.Henceforth this brand of justice could be referred to as “The Joe Biden Standard,” since it’s exactly the kind of show trial the presumptive Democratic nominee promises college kids via Title IX rules.When finally asked about Reade yesterday, Feinstein responded: “And I don’t know this person at all who has made the allegations. She came out of nowhere. Where has she been all these years? He was vice president.”To put this in perspective, when Ford came forward “out of nowhere,” Feinstein said: “Victims must be able to come forward only when they are ready.”What’s changed?During the Kavanaugh hearings Feinstein noted that “sharing an experience involving sexual assault — particularly when it involves a politically connected man with influence, authority and power — is extraordinarily difficult.”Is Biden not a politically connected man with influence, authority, and power? Feinstein is now arguing the opposite: She is saying we should dismiss Reade’s allegations because she failed to come forward against a powerful man earlier.But to answer Feinstein’s question about what Reade has been “up to” the past 27 years: Well, she’s been telling people that Biden had engaged in sexual misconduct. She relayed her story to her former neighbor, her brother, her former co-worker, and at least two other friends. It is also likely that her mother called Larry King Live asking for advice for her daughter the year of the alleged attack.Yesterday a document uncovered by local journalists in California -- somehow missed by Barack Obama’s crack vetting team -- shows Reade’s ex-husband bolstering her claim in 1996 divorce proceedings: “On several occasions [Reade] related a problem that she was having at work regarding sexual harassment, in U.S. Senator Joe Biden's office.”The reaction to the divorce papers has been extraordinary. Biden defenders argue that because Reade alleged “sexual harassment” -- a catch-all term used in the 1990s when men were getting away with despicable behavior far more often -- it proves her story has changed. Biden, through his deputy campaign manager Kate Bedingfield, alleges that “more and more inconsistencies” come up every day.Even if Reade didn't tell everyone everything that allegedly happened every time she mentioned the incident, that doesn’t definitively prove anything. If it did, none of us would have ever heard the name Christine Blasey Ford.Indeed, at time of Ford’s evolving story, there was a slew of journalists taking deep dives into the unreliability of memory and trauma and complexities of relaying assault allegations. I assume that science hasn’t changed in two years.Let’s also not forget that, despite Ford’s inconsistencies, Biden still argued that Kavanaugh should be presumed guilty. Why shouldn’t he?It is also quite amazing to see Biden’s defenders implicitly contending that Reade is only credibly claiming that she was sexually harassed for nearly 30 years, so her story must be politically motivated.Even if we concede that Reade is a wily Sanders operative or Putin stooge, what political motive could Reade possibly have had back in 1993 -- after working for Biden -- to smear the senator? What motive did she have to repeat that story to her family before Sanders was a candidate or Putin was running Russia?By the way, liberals have never argued that political motivations should be disqualifying. Ford came forward, by her own admission, because she did not believe the man who had allegedly assaulted her in high school should be given a seat on highest court in the land. Reade says she doesn’t want a man who allegedly assaulted her -- when he was in his 50s -- to hold the most powerful office in the world.Feinstein, of course, isn’t the only one to engage in this kind of transparent double standard. When asked about Reade, the idealist Alexandria Ocasio-Cortez, said, “I’m not sure. Frankly, this is a messy moment, and I think we need to acknowledge that -- that it is not clear-cut.”Where was all this hand-wringing and caution over the messiness of sexual-assault claims when nearly every Democrat and all their allies in the press were spreading Julie Swetnick’s alleged “gang rape” piece? Nowhere.AOC, whose position on Biden has evolved, invited Ana Maria Archila, the women who had famously cornered a weak-kneed senator Jeff Flake in an elevator and yelled at him about Kavanaugh, to the 2019 State of the Union address. Archila now says, “I feel very trapped.”I bet.People point out that there are numerous sexual-misconduct allegations leveled at Donald Trump. Indeed. If they haven’t yet, news outlets should scrutinize and investigate the credibility of those allegations, as they did for Biden but not for Kavanaugh. But it’s important to remember that Trump accuser E. Jean Carroll was given immediate and widespread coverage on cable news, while Reade reportedly wasn’t asked to tell her story by any major network -- save Fox News -- until this week.Of course, most Biden defenders are being purposely obtuse about the debate -- Mona Charen’s recent column is an excellent example. The problem isn’t that Biden is being treated unjustly, or that he should be treated unjustly; it’s that he is being treated justly by the same people who treat others unjustly. Democrats have yet to explain why Biden is afforded every benefit of the doubt but not Kavanaugh, and not millions of college students.Public figures such as Biden have every right to demand fair hearings and due process. Voters have every right to judge the credibility of both accuser and accused. Many women are victims. Many women are victims who are powerless to prove it. And some women are frauds. You can’t keep demanding that our political system adjudicate similar incidents under two completely differ set of rules. It’s untenable.

Senator Dianne Feinstein (D., Calif.) on Thursday attacked former Joe Biden staffer Tara Reade, who alleges she was sexually assaulted by Biden in the spring of 1993.Feinstein said the allegations were “totally different” than those against Supreme Court justice Brett Kavanaugh.“Kavanaugh was under the harshest inspection that we give people over a substantial period of time,” Feinstein told CNN on Thursday. “And I don't know this person at all [Reade] who has made the allegations [against Biden]. She came out of nowhere. Where has she been all these years? He was vice president.”Christine Blasey Ford, Kavanaugh's accuser, claimed that Kavanaugh sexually assaulted her in 1982, an allegation that was known by Feinstein's office before it was publicly reported in September 2018. Feinstein later denied that she or anyone in her office had withheld Ford's allegation for political purposes or had leaked the allegation to the press.Reade, meanwhile, called on Biden to drop out of the presidential race in an interview with Megyn Kelly released Thursday.“I want to say: You were there, Joe Biden. Please, step forward and be held accountable. You should not be running on character for the president of the United States,” Reade said.

Now Swain, 40, spends her evenings having dinner with her girls, age 5 and 8, and studying for her real-estate license, which she hopes will provide more long-term stability for her family after the coronavirus crisis upended her livelihood. "I can't be put in a position like this again," said Swain, a bartender for 20 years. American women are taking an outsized hit from the early wave of unemployment caused by the pandemic, due to the nature of the jobs that were lost in the business shutdowns to control the spread of the coronavirus.

Gregory McMichael and his son, Travis, were charged with murder and aggravated assault in relation to the shooting death of Ahmaud Arbery in February.

SAVANNAH—Gregory and Travis McMichael have been arrested and charged with murder and aggravated assault in connection with the February killing of Ahmaud Arbery, the Georgia Bureau of Investigation announced Thursday. According to police, the white father and son, 64 and 34, chased Arbery, a 25-year-old black man, after he ran by Travis McMichael’s home in the Satilla Shores neighborhood of Brunswick on Feb. 23. He was unarmed and jogging at the time. “This is a start towards victory,” Thea Brooks, Arbery’s aunt, told The Daily Beast on Thursday. “This only the beginning though, but this is what we were all hoping for.”The McMichaels said they believed Arbery was a burglar responsible for a series of break-ins in their neighborhood and that they pursued him in their pickup truck while armed with a shotgun and a .357 magnum. The GBI alleges the McMichaels confronted Arbery, and that Travis shot him. A local prosecutor previously indicated a third man, William Bryan, took part in the chase and filmed the incident.‘It’s Murder’: This Shooting of an Unarmed Black Man Is Roiling GeorgiaAt least two shots hit the 25-year-old, the Glynn County Coroner’s Office told The Daily Beast last week.Video that Brooks said depicted her nephew’s death elicited a furious reaction nationwide, and residents of the area protested the initial failure to prosecute a case on Tuesday.“It’s murder. It’s heartbreaking to even look at. The whole city has seen it,” Brooks told The Daily Beast after the video was released this week.The Georgia NAACP echoed her words in a Thursday response to the McMichaels’ arrest: “The murderers of Ahmaud Arbery have been arrested.”Gregory McMichael, a former cop and investigator with a local prosecutor’s office, previously told The Daily Beast he “never would have gone after someone for their color.” He also said the “closest version of the truth” about the incident was captured in a letter effectively clearing him and his son that was written by a prosecutor who recused himself from the case, George Barnhill. McMichael also admitted he had no direct evidence that Arbery was a thief. “But he’s the guy who’s there without permission,” he said from behind the closed front door of his son’s home.The owner of an unfinished home just down the street from Travis McMichael's home, Larry English, told The Daily Beast earlier this week that he had surveillance footage that appeared to show Arbery stopping to look at the foundation of his still-under-construction home. While Gregory McMichael claimed to police that Arbery had been caught on surveillance video, it was not immediately clear what video he was referring to. English told The Daily Beast he had no knowledge of the McMichaels seeing his surveillance footage. McMichael’s ties to law enforcement helped fuel a haze of suspicion around the killing from the beginning. Barnhill was one of two area prosecutors who looked into the incident before recusing themselves. A third prosecutor—District Attorney Tom Durden—sought a GBI probe ahead of the arrests this week.Read more at The Daily Beast.Got a tip?
