Put another way, more Black children in metro Phoenix will go through a child maltreatment investigation than won’t. Almost all described a system so omnipresent among Black families that it has created a kind of communitywide dread: of that next knock on the door, of that next warrantless search of their home. Many Black families first moved there as a result of redlining and racial covenants that blocked them from renting or owning property elsewhere. In Maricopa County, Black children experienced child welfare investigations at one of the highest rates among large counties nationally, and nearly three times the rate of their white peers, from 2015 to 2019. But throughout the country, investigations were more pervasive among Black families.
There is no evidence that food products contain cells from aborted human fetuses as flavor enhancers, contrary to a social media claim that revives a related, previously-debunked charge about cells used in biomedical research. Research by Senomyx into the use of ‘HEK-293’ aborted human fetal cells as a flavor enhancer was published in Pubmed in 2002, after which several patents were filed by them. Reuters previously factchecked false claims that PepsiCo drinks contained aborted fetal cells. AN OLD CELL LINEThe controversial cell line is derived from fetal cells dating to the 1970s. There is no evidence that any food or beverage products contain cells from human fetuses or derived from fetuses.
And Wagner’s beloved fireflies – like so many insects worldwide – have largely vanished in what scientists are calling the global Insect Apocalypse. “Insects are the food that make all the birds and make all the fish,” said Wagner, who works at the University of Connecticut. Humans, too, see some 2,000 species of insects as food. “We’d see yields dropping of all of these crops.”And in nature, about 80% of wild plants rely on insects for pollination. WINNERS AND LOSERSWhile the situation is bleak for insects at large, a few types of insects are thriving.
She suspected the gray and brown splotches spreading through the apartment were mold and had caused her son’s illness. A nationwide affordable housing crisis has wreaked havoc on the lives of low-income families, like Joseph’s, who are close to the brink. Housing instability — such as having trouble paying rent, living in crowded conditions, or moving frequently — can have negative consequences on health, according to the federal Office of Disease Prevention and Health Promotion. And there is no county in the country where a minimum-wage worker could afford a two-bedroom rental home, according to an August report from the National Low Income Housing Coalition. A few months after leaving the apartment, Joseph and her two children moved in with her sister in Orlando, Florida, with their remaining possessions — a car and some clothes.
Opinion | Science Has a Nasty Photoshopping Problem

One evening in January 2014, I sat at my computer at home, sifting through scientific papers. Manipulated imagery in scientific papers can look ordinary at first glance. However, this ability, combined with my — what some might call obsessive — personality, helped me when hunting duplications in scientific images by eye. So when a scientist’s research shows a negative result, cheating can be tempting. Legitimate criticism of scientific research should receive legal protection.
Disdain and defiance among Kyiv residents after Putin order

Russian President Vladimir Putin makes an address on the conflict with Ukraine, in Moscow, Russia, in this still image taken from video released September 21, 2022. Register now for FREE unlimited access to Reuters.com Register"I still believe Putin isn't insane, there is some rationality in him. 'EMPTY WORDS'There was strong support among Kyiv residents for Ukraine's own armed forces, who helped by Western arms have been battling Russia's much bigger military for nearly seven months on several fronts and recaptured swathes of land in recent weeks. "I think we have to trust our armed forces and no one else. I believe in Ukraine's armed forces and hope that nothing bad will happen and that we will be defended.
The world’s vital insect kingdom is undergoing “death by a thousand cuts,” the world’s top bug experts said. Wagner said scientists need to figure out if the rate of the insect loss is bigger than with other species. “There is some reason to worry more,” he added, “because they are the target of attack” with insecticides, herbicides and light pollution. Honeybees have been in dramatic decline because of disease, parasites, insecticides, herbicides and lack of food. Scientists have identified 1 million insect species, while probably 4 million more are still to be discovered, Berenbaum said.
According to a new study, there are estimated to be 2.5 million times more ants on this planet than people. In total, that's 20 quadrillion — or 20,000,000,000,000,000 — ants. Taken together, the total mass of ants on the planet would actually outweigh all of the world’s wild birds and mammals, he added. Jorge Villalba / Getty Images / iStockphotoAnts can be found in nearly all habitats except for polar regions, according to the study. A separate study published in April 2020 in the journal Science found that the planet has lost more than one-quarter of its land-dwelling insects in the past 30 years.
Scientists have estimated the number of ants on earth, which is "unimaginable," a study author said. Per the study, there are 20 quadrillion ants on earth— 20 followed by 15 zeros. That's about 2.5 million ants per human. The astonishing number — 20,000,000,000,000,000 — means there would be about 2.5 million ants per single human living today. "We simply cannot imagine 20 quadrillion ants in one pile, for example.
No one knows what all the sperm whale codas mean, but they can have distinctive rhythms and tempos, known as “dialects,” Hersh said. They’ve now determined that there are at least seven distinct sperm whale “vocal clans” across the Pacific Ocean, each with their own identity codas, Hersh said. And the sperm whale clans may be thousands of years old. Beguš is part of Project CETI — the Cetacean Translation Initiative — which was established last year to decipher the sounds of sperm whales. “As the authors note, we still understand little about the function of sperm whale codas,” she said in an email.
Air pollution takes a toll on your lungs and can be bad for your brain, increasing psychological stress and cognitive decline in adults. At least 85 cancer cases per year in the state are due to exposure to high levels of air pollution, according to a January 2022 study from Tulane University. Nevada's status as the second-most polluted state is also seemingly well deserved: In 2021, the American Lung Association also ranked the state's air quality among "the unhealthiest for the most harmful and widespread types of air pollution." Oregon's website notes that cars and trucks are the state's largest source of air pollution, and frequent wildfires only worsen the state's poor air quality. Vermont's cities are among the cleanest by air quality in the country, and have particularly low levels of the most harmful types of air pollution, the ALA says.
Ancient Egyptians built the spectacular Giza pyramids in what is now a desert landscape. The Sphinx at the Giza Pyramids on November 20, 2019. Khufu's pyramid, known as the Great Pyramid, was the first to be built and the biggest of the three. The Great Pyramid is the oldest of the famed Seven Wonders of the Ancient World and the only one to remain largely intact. An Egyptian walks at the Giza Pyramids in Egypt, on April 26, 2021.
Here's what parents of successful kids have in common, according to research. Children with parents who stepped in to provide instructions frequently displayed more difficulty regulating their emotions later, the researchers wrote. "Too much direct engagement can come at a cost to kids' abilities to control their own attention, behavior and emotions. When parents let kids take the lead in their interactions, children practice self-regulation skills and build independence," Obradović wrote in the study. The parents tend to take parental leave.
Математические навыки связаны с рядом преимуществ, включая занятость, социально-экономический статус, а также психическое и физическое здоровье. Изучение математики стимулирует когнитивное развитие подростков. Основываясь на количестве химического вещества в мозге каждого участника эксперимента, исследователи смогли различить подростков, которые изучали или не изучали математику, независимо от их когнитивных способностей. Учитывая важность математики и то, что она нравится не каждому подростку, важно найти возможные альтернативы дисциплине, которые задействуют ту же область мозга. Кадош добавила, что исследование дает важное понимание того, "как отсутствие даже одного-единственного компонента в образовании может повлиять на мозг и поведение".

Люди не могут видеть мир объективно, доказал эксперимент исследователей из Университета Джонса Хопкинса. «В философии вопрос о влиянии собственной точки зрения на восприятие обсуждали в течение многих столетий, — сказал старший автор исследования Чаз Файрстоун. Испытуемым девять раз показывали пары монет, одна из которых была овальной, другая — круглой. «Этот результат удивил нас — мы ожидали, что "объективность" полностью подавит любое влияние точки зрения субъекта, — сказал Файрстоун. Даже когда мы пытаемся воспринимать мир таким, какой он есть на самом деле, мы не можем полностью отбросить наше видение», — добавил ведущий автор Хорхе Моралес.

Значит ли это, что Земле не грозит «шестое вымирание»? Это вымирание видов в целом уравновешивалось возникновением новых. Что такое «шестое вымирание»? Это продолжающееся вымирание видов совпадает с современной эпохой голоцена и во многом является результатом человеческой деятельности. Нынешние темпы вымирания видов оцениваются в 100 - 1000 раз выше естественных фоновых показателей.

Pământul găzduiește circa 50 de miliarde de păsări care fac parte din 9 700 de specii cunoscute, estimează un studiu australianTerra găzduieşte circa 50 de miliarde de păsări, aproape de şase ori mai mult decât numărul oamenilor, potrivit unei estimări realizate de oameni de ştiinţă australieni şi publicată în revista Proceedings of the US National Academy of Sciences. Cercetătorii au asociat sondaje ştiinţifice ale unor specii individuale care trăiesc în anumite zone de distribuţie cu cele aproape un miliard de înregistrări din baza de date ornitologică online eBird. Cercetătorii au ajuns la concluzia că există relativ puţine specii comune şi multe specii rare. Printre cele mai răspândire 10 specii de păsări din lume se numără vrabia de casă (1,6 miliarde), graurul (1,3 miliarde), pescăruşul cu inel (1,2 miliarde) şi rândunica (1,1 miliarde). „Există un număr considerabil de exemplare de păsări în lume (50 de miliarde), dar a înţelege pe deplin de ce şi cum fiecare populaţie a ajuns la mărimea actuală va fi primordial pentru studiul viitor al evoluţiei, ecologiei şi conservării”, au menţionat cercetătorii.

Ученые выявили главный фактор, влияющий на продолжительность жизни. Об этом сообщает журнал Proceedings of the National Academy of Sciences. Исследователи на протяжении 20 лет изучали замкнутую популяцию короткоживущих диких овец в Шотландии. Они проанализировали связь между длиной теломер (концевых участков хромосом), их сохранностью и продолжительностью жизни и пришли к выводу, что долголетие коррелирует с длиной теломер и не связано со степенью их истощения. Таким образом, отмечают ученые, на срок жизни больше влияет генетическая предрасположенность, нежели внешние факторы, такие как стресс или питание.

Erg Chech 002 este un obiect rar în mai multe privinţe. Însă, în cazul Erg Chech 002, „aceasta este prima dată când avem un fragment din scoarţa”acestor corpuri cereşti. Iar pentru a intra în posesia lui a fost nevoie de o combinaţie de circumstanţe la fel de excepţionale ca obiectul în sine. Singura explicaţie ar fi aceea că „roca a fost proiectată în spaţiul îngheţat”, în urma unui şoc, după cum a explicat Jean-Alix Barrat. Până în urmă cu 26 de milioane de ani, când micul asteroid care îl conţinea a fost spulberat, iar roca a fost expusă la soare în ultima sa etapă.

„Corpul-părinte” al lui Erg Chech 002 avea probabil o lungime de o sută de kilometri.

Astfel, cercetătorii au creat un scor „asemănător creditului” pentru virusuri ca o modalitate de evaluare și comparare a riscurilor lor. Pentru a obține scorul, instrumentul ia în considerare 32 de factori de risc asociați cu virusul și gazda acestuia, cum ar fi câte specii de animale infectează virusul și cât de des interacționează oamenii cu animale sălbatice în zonele în care virusul a fost detectat. Animalele principale gazdă pentru SARS-CoV-2 sunt necunoscute, dar s-a constatat că virusul infectează nurcile, leii și tigrii. ) Autorii au spus că s-au așteptat la acest rezultat - cunoscut clasamentul zoonozelor în partea de sus - și l-au folosit pentru a valida instrumentul. Un alt virus de top este coronavirusul PREDICT CoV-35, care aparține și familiei coronavirusului și infectează liliecii din Africa și Asia de Sud-Est.
