watch now"For mothers, employment and earnings conditional on being employed fall sharply around the time of birth for women, and, more ominously, may remain permanently lower well after childbirth," the authors of the PNAS study wrote. There is a dynamic that perpetuates itself, according to Jasmine Tucker, vice president of research at the National Women's Law Center. Alternatively, fathers who work full time experience a wage "bonus" when they have children, according to a separate report by the British trade union association TUC. "The gender imbalance in time spent on caregiving persists, even in marriages where wives are the breadwinners." In fact, the motherhood penalty is even greater in "female-breadwinner" families, the PNAS study also found, where higher-earning women experience a 60% drop from their pre-childbirth earnings relative to their male partners.

It’s a scene most of us might associate with an open savannah in a nature documentary, but photographer Andy Murray is watching the drama unfold from his back garden in Somerset, UK. To Murray, these microscopic soil animals are as fascinating as the lions and zebras you might see on safari – just far more accessible, if you know where to look. “They live in this tiny world; it works like our world, it’s just on a really small scale,” he tells CNN. Andy MurrayYet despite this wealth of life, the creatures living in the soil beneath our feet are relatively unknown. “He captures moments of soil life doing interesting and cool things,” says Anthony, such as laying eggs in a place where we would never expect.

☆ Brazil child cancer deaths linked to soy farming, study finds
▼ + stars: | 2023-11-01 | by ( Ana Mano | ) www.reuters.com time to read: +2 min

The U.S. researchers found a relationship between soy production and related community exposure to agrochemicals including glyphosate, a widely used weedkiller that some genetically modified soybean seeds are designed to tolerate. "We find a statistically significant increase in pediatric leukemia following expanded local soy production," the PNAS article said, based on Brazilian childhood cancer incidence and disease mortality data spanning 15 years. Specifically, the study found a correlation between soy farming and childhood blood cancers, especially acute lymphoblastic leukemia (ALL), the most common blood cancer in children. There were 123 additional deaths of children under age 10 from 2008 to 2019 from ALL following the expansion of soybean production in Brazil, the researchers found. That number would have been higher were it not for the country's high-quality cancer treatment centers, the researchers said.

"It's very disturbing," study co-author Matthew Huber of Purdue University in the U.S. state of Indiana told Reuters. It found that around 750 million people could experience one week per year of potentially deadly humid heat if temperatures rise 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels. At 4C of warming, Hodeidah, Yemen, would see around 300 days per year of potentially unsurvivable humid heat.

London CNN —A pod of more than 50 pilot whales has died after a mass stranding on a northwestern Scottish island, according to a marine charity on the ground. Pilot whales are sociable animals, so if one becomes stranded, experts believe others from the pod will follow and also become stranded. Known to be gregarious, pilot whales have “extremely strong social and emotional bonds with one another,” Jarvis told CNN. In the UK, the largest stranding of pilot whales was in Scotland in 2011, when 77 were found stuck on the country’s northerly shores, according to Jarvis. Tasmania’s largest stranding was in 2020, when more than 450 pilot whales were found.

☆ Fried food is linked to increased risk of anxiety and depression
▼ + stars: | 2023-04-24 | by ( Taylor Nicioli | ) edition.cnn.com time to read: +6 min

A research team in Hangzhou, China, found that frequent consumption of fried foods, especially fried potatoes, was linked with a 12% higher risk of anxiety and 7% higher risk of depression than in people who didn’t eat fried foods. These results “open an avenue in the significance of reducing fried food consumption for mental health,” according to the paper published Monday in the journal PNAS. Frequent consumption of fried foods was linked to higher risk of anxiety and depression. Dr. Walter Willett said the results “should be regarded as very preliminary, especially the connection with fried food and acrylamide.”“The health effects of fried food will depend greatly on what food is fried and what type of fat is used for frying,” said Willett, professor of epidemiology and nutrition at Harvard T.H. It's also possible that some people with mental health issues reach for fried food.

☆ Rising sea levels may have forced the Vikings out of a successful settlement
▼ + stars: | 2023-04-18 | by ( Katie Hunt | ) edition.cnn.com time to read: +4 min

Why they abandoned a successful settlement is a mystery that historians never have been able to fully explain. The idea that sea levels would have been rising as temperatures fell is a little counterintuitive, according to the researchers. However, Earth’s oceans aren’t like a bathtub, and the study noted that changes in sea level don’t affect all areas equally. The Greenland Ice Sheet readvanced during Viking occupation of the eastern settlement and peaked in the Little Ice Age. That advance caused sea level rise near the ice margins because of the sinking of Earth’s crust, according to the study.

☆ California's 'zombie forests' are 'cheating death' as the climate has changed so drastically it's no longer able to support them

A new study found some of the forests in California's Sierra Nevada no longer match their climate. About 20% of conifers in the Sierra Nevada are experiencing "vegetation climate mismatch." The lead author said the trees are "cheating death" but that they won't survive a major disturbance. When trees or other plants are no longer suited to the environment they are in, it's called a "vegetation climate mismatch." The conifers of the Sierra Nevada include ponderosa pine, sugar pine, and Douglas fir.

That's according to two studies that were published in August and November of this year, which researched how exposure to younger kids and common colds may impact outcomes for adults after contracting Covid-19. Exposure to kids may lower your risk of hospitalization from Covid-19The study, published in Proceedings of the National Academy of Sciences (PNAS) in August, discovered an association between people who were exposed to young children and lower risk of severe illness from Covid-19. And researchers compared the severity of outcomes from Covid-19 for people without children and people with children in three different age ranges: 0-5, 6-11 and 12-18. The findings showed that chances of Veteran Affairs patients contracting Covid-19 decreased by 80% to 90% if they tested positive for any of the common coronaviruses between February 2020 and February 2021. This means developing a common cold may shield people from Covid-19 infection, even if for a short period time.

☆ Chimpanzees could share another behavior trait with humans

The closest cousin of humans, this species of great ape has effective ways of communicating what it needs. Show-and-tellFiona had been engaged in what researchers call “leaf grooming,” a common behavior in which a chimpanzee will stroke and manipulate a leaf. Slocombe and her team always maintain a 23-foot (7-meter) distance when observing the chimpanzees in the wild, so as to not disturb them. This standard practice rules out the possibility that the behavior was learned from humans. She hopes it will encourage those who work with chimpanzees, in the wild or in captivity, to look out for more examples.

☆ Money can buy happiness for households earning up to $123,000, study suggests

A recent experiment suggests that money can indeed buy happiness — at least for six months, among households making up to $123,000 a year. The group that got $10,000 reported higher levels of happiness than those who did not after their three months of spending. Then, after three more months had passed, the recipients still reported levels of happiness higher than when the experiment started. Ania Jaroszewicz, a behavioral scientist at Harvard University, said there is still no scientific consensus about whether money can buy happiness. Jaroszewicz highlighted that in any study of money and happiness, outcomes can also depend on the particular circumstances of people's lives and their expectations.

☆ Врачи назвали ключ к здоровью печени

Пожилой возраст может способствовать развитию жировой болезни печени, но чаще всего ее причиной являются нездоровые привычки питания, ожирение и другие признаки метаболического синдрома. Ученые пришли к выводу, что клинические испытания на людях будут полезны для определения того, будет ли пищевой нитрат полезным для лечения и профилактики жировой болезни печени. Будучи одним из продуктов питания, который ученые назвали отличным для вашей печени, она не только легкодоступна в магазинах и недорога, учитывая ее питательную пользу, но ее также легко выращивать. Кроме того, по данным Института Линуса Полинга, в одной чашке содержится 8,2 миллиграмма хлорофилла, что способствует заживлению ран и, что более важно, помогает предотвратить заболевание печени. Он может также быть вызван НАЖБП (у которой в названии указывается, что это «неалкогольное» заболевание печени), а также ожирением и гепатитом.

☆ STUDIU: Neînvăţarea matematicii afectează dezvoltarea cerebrală a adolescenţilor

Lipsa de educaţie matematică afectează negativ dezvoltarea cerebrală şi cognitivă a adolescenţilor, potrivit unui studiu care sugerează că neînvăţarea acestei materii după vârsta de 16 ani poate fi un dezavantaj, relatează EFE.Studiul, publicat de revista PNAS şi la care au participat 133 de elevi cu vârste cuprinse între 14 şi 18 ani, a fost realizat de departamentul de Psihologie Experimentală de la Universitatea Oxford, scrie agerpres.ro Studiul a relevat că elevii care nu învăţau matematica avea o cantitate mai mică a unui aminoacid crucial pentru plasticitatea cerebrală (acidul gamma-aminobutiric - GABA) dintr-o zonă cheie în care intervin multe funcţii cognitive importante, precum raţionamentul, rezolvarea problemelor, memorarea şi învăţarea.Bazându-se pe cantitatea acestui aminoacid deţinută de fiecare elev, cercetătorii au putut face o deosebire clară între cei care studiau şi cei care nu învăţau matematica, indiferent de capacităţile lor cognitive.De asemenea, cantitatea de acid gamma-aminobutiric a prognozat cu succes reuşitele în acest domeniu 19 luni mai târziu, potrivit Universităţii Oxford.Roi Cohen Kadosh, profesor de neuroştiinţă cognitivă la Oxford a explicat că abilităţile matematice sunt asociate unei serii de avantaje legate de obţinerea unui loc de muncă, de statutul socio-economic, sau de sănătatea mentală şi cea fizică. "Adolescenţa este o perioadă importantă din viaţă asociată unor schimbări cerebrale şi cognitive. Din păcate, a renunţa la matematică la această vârstă poate provoca o breşă între adolescenţii care abandonează această materie şi cei care continuă să o studieze", a spus el.Acest studiu, potrivit autorilor, oferă un nou nivel de înţelegere biologică a impactului pe care îl are educaţia în dezvoltarea creierului şi a efectului reciproc între biologie şi educaţie. Însă nu toţi adolescenţii continuă să înveţe matematica, astfel încât trebuie investigate şi posibile alternative, discipline ca logica sau raţionamentul care implică aceeaşi zonă cerebrală. "Deşi am început acest studiu înainte de pandemia de COVID-19, mă întreb cum se va repercuta lipsa accesului la educaţie, în general, şi la matematică, în particular, asupra dezvoltării cerebrale şi cognitive a copiilor şi a adolescenţilor", a mărturisit profesorul Roi Cohen Kadosh.

Încă de la începutul revoluției industriale, oamenii au fost principalul factor care a dus la criza de mediu a pământului. Există voci care susțin că schimbările climatice și dispariția speciilor de animale sunt o parte naturală a vieții și, într-un fel, este adevărat, potrivit Live Science. Cu toate acestea, tehnologia este încă la început și este limitată în zonele împădurite și nu poate monitoriza decât animalele mari. Cercetătorii lucrează la îmbunătățirea acestui algoritm, pentru a putea monitoriza și animale mai mici, și pe cele care umblă în colonii sau turme.

Итальянские онкологи обнаружили антитела на коронавирус в анализах крови, взятых в сентябре 2019 года. Считается, что коронавирус SARS-CoV-2 появился в Китае примерно год назад. Однако по последним данным, коронавирус нового типа уже существовал в сентябре 2019 года — и не в Китае, а в Италии, сильно пострадавшей потом во время первой — весенней — волны пандемии. Коронавирус был в Италии раньше, чем предполагалосьИсследование итальянских ученых, установившее, что первые бессимптомные пациенты с атипичной пневмонией, вызванной SARS-CoV-2, были в Италии еще в сентябре 2019-го, стало не единственным доказательством появления коронавируса в Европе еще в прошлом году, до официальной вспышки пандемии. Анализ сточных вод на севере Италии, результаты которого были обнародованы в июне, также указывал на то, что коронавирус циркулировал в стране еще в конце 2019 года.
