Better catch the moon’s disappearing act Tuesday — there won’t be another like it for three years. The total lunar eclipse will be visible throughout North America in the predawn hours — the farther west, the better — and across Asia, Australia and the rest of the Pacific after sunset. As an extra treat, Uranus will be visible just a finger’s width above the moon, resembling a bright star. Totality will last nearly 1 1/2 hours — from 5:16 a.m. to 6:42 a.m. EST — as Earth passes directly between the moon and sun. Known as a blood moon, it will appear a reddish orange from the light of Earth’s sunsets and sunrises. At the peak of the eclipse, the moon will be 390,653 kilometers away, according to NASA scientists. Binoculars and telescopes will enhance viewing, provided the skies are clear. South America will get a glimpse of Tuesday’s lunar eclipse, weather permitting. Striking out altogether, Africa, the Middle East and most of Europe will have to wait until 2025. Among those providing a livestream of Tuesday’s lunar extravaganza: Griffith Observatory in Los Angeles and the Italian-based Virtual Telescope Project. It’s the second total lunar eclipse this year; the first was in May. The next one won’t be until 2025. Plenty of partial lunar eclipses will be available in the meantime. …

When world leaders, diplomats, campaigners and scientists descend on Sharm el-Sheikh in Egypt for talks on tackling climate change, don’t expect them to part the Red Sea or other miracles that would make huge steps in curbing global warming. Each year there are high hopes for the two-week United Nations climate gathering and, almost inevitably, disappointment when it doesn’t deliver another landmark pact like the one agreed 2015 in Paris. But those were different days, marked by a spirit of cooperation between the world’s two biggest polluters — the United States and China — as well as a global realization that failure to reach an agreement would put humanity on a self-chosen track to oblivion. This November the geopolitical tiles have shifted: a devastating war in Ukraine, skyrocketing energy and food prices, and growing enmity between the West on the one hand and Russia and China on the other make for difficult conditions at a gathering that requires cooperation and consensus. “There’s a lot of high and low expectations around this Egypt COP, a lot of mix of ambition and fatalism,” said Avinash Persaud, special envoy for the Barbados prime minister. Here’s what to look out for during the 27th Conference of the Parties, or COP27, from Nov. 6-18 and why it might still end up being a success. Science warnings Scientists are more concerned about global warming than three decades ago, when governments first came together to discuss the problem because the pace of warming in the past decade …

World health officials are linking a significant rise in African Ebola outbreaks in this century to climate change.     Uganda’s September 20 Ebola outbreak is just the latest in a growing number of eruptions of this deadly hemorrhagic disease in Africa. Since 2000, the World Health Organization has reported 32 outbreaks of Ebola, 19 in the last decade compared to 13 in the preceding one. Ebola is one of a range of zoonotic diseases — infections originating in animals and jumping to humans. A WHO analysis finds Ebola and other viral hemorrhagic fevers constitute nearly 70% of these outbreaks. The remaining 30% include dengue fever, anthrax, plague, and monkeypox.   WHO Africa incident manager for the Ebola outbreak in Uganda, Patrick Otim, says the number of zoonotic diseases occurring in the region in the last decade has increased by more than 63%. “There have been a couple of researchers that have shown a possible link between the climatic changes that we are seeing and the increase in zoonotic diseases, and for this particular case for Ebola, for instance,” he said. Otim said diseases are caused by several factors. Ebola, he said, is strongly influenced by the human factor. As populations increase and people encroach on wildlife habitats, interaction with animals increases. This, he said, increases the spread of disease to humans. Otim said temperature and climatic changes also spur migration and movement of some Ebola virus hosts.  “For the Ebola virus, we know that the bats and other animals are hosts of …

Astronomers have discovered the closest known black hole to Earth, just 1,600 light-years away. Scientists reported Friday that this black hole is 10 times more massive than our sun. And it’s three times closer than the previous record-holder. It was identified by observing the motion of its companion star, which orbits the black hole at about the same distance as Earth orbits the sun. The black hole was initially identified using the European Space Agency’s Gaia spacecraft, said Kareem El-Badry of the Harvard-Smithsonian Center for Astrophysics. El-Badry and his team followed up with the International Gemini Observatory in Hawaii to confirm their findings, which were published in Monthly Notices of the Royal Astronomical Society. The researchers are uncertain how the system formed in the Milky Way. Named Gaia BH1, it’s located in the constellation Ophiuchus, the serpent-bearer. …

More than 120 world leaders will attend this year’s U.N. climate talks, and requests by environmental activists to stage a rally during the event would be responded to “positively,” host Egypt said. Veteran diplomat Wael Aboulmagd, who heads the Egyptian delegation, told reporters Friday that his country had been working for months to set the scene for “meaningful outcomes” at the two-week meeting in the Red Sea coastal resort of Sharm el-Sheikh starting Sunday. “We have, I think about 121 maybe, and the number is growing, heads of state and government here,” he said during an online briefing. “We hope that it will be a watershed moment.” Leaders such as U.S. President Joe Biden and British Prime Minister Rishi Sunak confirmed their attendance, but Aboulmagd said other major heads of state such as China’s Xi Jinping and India’s Narendra Modi would not be going. Aboulmagd said recent scientific reports highlighted the urgency of tackling global warming. “Everyone is now aware of the gravity of the situation, of the enormity of the challenge, and have come here hopefully to work together,” he said. Greenhouse gases, financial aid Several thorny issues will be discussed at the November 6-18 talks, including further cutting greenhouse gas emissions and boosting financial aid for poor countries struggling with the impacts of climate change. It is the first such meeting held in Africa since 2016. Over 40,000 people have registered for the event. Aboulmagd appealed to negotiators to engage constructively. “We cannot afford to waste any time,” …

In South Africa, a country where ‘braai’ all-day barbecuing is a national pastime, plant-based substitutes are making surprising inroads despite a deep cultural love of meat and hostility from the regulator. That could be heartening for climate scientists, who say shifting diets from emissions-heavy meat and dairy towards more plant-based foods is vital to the fight against climate change. Plant-based meat substitutes are growing by 6.5% a year and sales are expected to reach $561 million by 2023, according to Research and Markets – more than half Africa’s share of a global market forecast to hit $162 billion by 2030. That is still pretty niche – South Africans spent $15 billion on meat products in 2018 and is now the world’s 9th biggest per capita consumer of beef. But the popularity of veggie alternatives would have been unthinkable even a decade ago and the market is outstripping forecast growth for meat. The shift has so unnerved South Africa’s processed meat industry that in June it lobbed for – and got – a government ban on plant-based products using words like ‘nugget’, ‘sausage’ or ‘burger’ on packaging. The agriculture department at the time said the move was aimed at preventing consumer confusion. A spokesperson did not respond to repeated requests for comment. Food producers remain undeterred. At meat processor Feinschmecker, staff pour powdered soy and pea protein into vats and rehydrate them to make its plant-based ‘deli slice’ – called so in anticipation of a ban on labeling it ‘ham’. “A …

The U.S. flu season is off to an unusually fast start, adding to an autumn mix of viruses that have been filling hospitals and doctors’ waiting rooms. Reports of flu are already high in 17 states, and the hospitalization rate hasn’t been this high this early since the 2009 swine flu pandemic, according to the Centers for Disease Control and Prevention. So far, there have been an estimated 730 flu deaths, including at least two children. The winter flu season usually ramps up in December or January. “We are seeing more cases than we would expect at this time,” the CDC’s Dr. José Romero said Friday. A busy flu season is not unexpected. The nation saw two mild seasons during the COVID-19 pandemic, and experts have worried that flu might come back strong as a COVID-weary public has moved away from masks and other measures that tamp the spread of respiratory viruses. Community Montessori school in New Albany, Indiana, switched to virtual teaching at the end of the week because so many students were out sick with the flu. Beginning Monday, the school’s 500 students will go back to wearing masks. “Everybody just wants kids on campus, that is for sure,” said the school’s director, Burke Fondren. “We will do what we need to do.” There may be some good news: COVID-19 cases have been trending downward and leveled off in the past three weeks, Romero said. And in a few parts of the country, health officials think they may …

The lone volunteer in a study involving a gene-editing technique has died, and those behind the trial are now trying to figure out what killed him. Terry Horgan, a 27-year-old who had Duchenne muscular dystrophy, died last month, according to Cure Rare Disease, a Connecticut-based nonprofit founded by his brother, Rich, to try and save him from the fatal condition. Although little is known about how he died, his death occurred during one of the first studies to test a gene editing treatment built for one person. It’s raising questions about the overall prospect of such therapies, which have buoyed hopes among many families facing rare and devastating diseases. “This whole notion that we can do designer genetic therapies is, I would say, uncertain,” said Arthur Caplan, a medical ethicist at New York University who is not involved in the study. “We are out on the far edge of experimentation.” The early-stage safety study was sponsored by the nonprofit, led by Dr. Brenda Wong at the University of Massachusetts Chan Medical School and approved by the Food and Drug Administration. The hope was to use a gene-editing tool called CRISPR to treat Horgan’s form of Duchenne muscular dystrophy. The rare, genetic muscle-wasting disease is caused by a mutation in the gene needed to produce a protein called dystrophin. Most people with Duchenne die from lung or heart issues caused by it. At this point, it’s unclear whether Horgan received the treatment and whether CRISPR, other aspects of the study or …

A court in Senegal has dismissed a lawsuit by a fishermen’s collective against a fishmeal factory they had accused of polluting their village and destroying their livelihoods. Dozens of people filtered into the Thies courthouse Thursday to hear the judge’s decision. The lawsuit, filed by the Taxawu Cayar Collective against the Touba Proteine Marine fishmeal factory, accused the factory of polluting the town of Cayar’s air, soil and water. The collective had asked for the temporary closure of the factory based on urgency. During the legal proceedings, the collective presented video footage of the factory’s truck dumping fish waste into Cayar’s lake. An independent laboratory analysis revealed high levels of toxic metals in the lake, which was also found in the town’s tap water. The collective is now deciding whether to appeal the decision or to bring forward new litigation that would permanently shut down the plant. “We will pursue all possible legal avenues while respecting the laws of this country, said Alle Sy, a member of the fisherman’s collective. “We will never give up, as this is a battle close to our hearts.” Boubacar Cisse, the lawyer for the fishmeal factory, formerly known as Barna Senegal, said the factory plans to take action against the collective. “He says the factory is more than 3 km away from Cayar, so how could a business like that pollute the air and make it unbreathable?” asked Cisse. “Obviously, Barna Senegal will retaliate against these people for having discredited the factory and tarnishing …

U.S. pharmaceutical company Pfizer and its German partner BioNTech said Friday a new study indicates their COVID-19 booster vaccination provides significant antibody protection against the omicron variant and its subvariants among adults. The companies introduced a new booster targeting the omicron variant in September, and U.S. Food and Drug Administration (FDA) approved it for use last month, along with a similar vaccine produced by U.S. drug company Moderna, as have several other countries. In their statement, the companies said the new data show the COVID-19 booster, adapted to target the omicron BA.4 and BA.5 subvariants, generated four times the neutralizing antibodies against the omicron variants among adults ages 55 and older than their original vaccine. The study also showed after one month, the booster dose generated more than 13 times the number of neutralizing antibodies against the variants in patients older than 55 than patients who received the original vaccine; 9.5 times the antibodies in patients 18 to 55 years old. Pfizer Chairman and Chief Executive Officer Albert Bourla said in the statement that as the United States heads into the holiday season, the new data should encourage people who have not done so to seek out a booster shot as soon as they are eligible to receive it — six months after their last vaccination. Pfizer and BioNTech said they have shared the data with the FDA and plan to share it with the European Medicines Agency and other global health authorities as soon as possible. A booster dose …

Australia can expect another wave of COVID-19 infections in coming weeks, according to experts, as new variants circulate. Coronavirus cases are rising quickly in New South Wales and Victoria, Australia’s most populous states. The World Health Organization declared COVID-19 a global pandemic on March 11, 2020. The declaration is still active. In Australia, life is resembling what it was before the virus. Most disease-control measures, such as mandatory mask-wearing on public transport and self-isolation for people testing positive to COVID-19, have been scrapped. Some restrictions, however, still apply to health, disability and aged-care facilities. Public health authorities in the states of New South Wales and Victoria have warned that another surge in infections is approaching. Official data has shown that in the last week of October, coronavirus case numbers increased in all Australian states and territories except Queensland. There were 9,707 positive diagnoses in the week ending Oct. 29 in New South Wales, an 11% increase from the previous week. Government data has shown that more than 95% of Australians over 16 have had at least two doses of a COVID-19 vaccine. In a video posted on Twitter on Thursday, New South Wales Chief Health Officer Kerry Chant warned of a spike in infections. “By looking at all the local information we have and what is happening overseas we believe COVID cases will rise in the coming weeks,” Chant said. “The protection the New South Wales community has from vaccination and previous infection continues to reduce the risk of severe …

Tanzania’s Ministry of Tourism released a census this week showing the country’s elephant population has stabilized. Tanzania’s elephants were among the hardest hit by poaching in Africa, with numbers dropping 60 percent between 2009 and 2014. But authorities say joint efforts with conservation groups and local communities have drastically reduced poaching and helped to attract tourist dollars. Just under 20,000 elephants were recorded in a survey that covered about 90,000 square kilometers of the Katavi-Rukwa and Ruaha-Rungwa landscapes in western Tanzania, including parks, game reserves and other protected areas. The government said the results confirm that the landscape remains the most important in East Africa in terms of elephant numbers and contains the largest population on the continent outside Zimbabwe and Botswana. Ernest Mjingo, a managing director of the Tanzania Wildlife Research Institute, a department of the Ministry of Tourism, said the world would now see Tanzania as very serious about conservation and doing well at it. And if the world does see that, he said, it would be a credit to the government and would also increase revenue, because Tanzania will become a prime destination for tourists because of the animal population. He added that it could also become a U.N. World Heritage Site, since it would have species that would not be available in other places. The report said poaching had dramatically decreased over the last few years. In the last report, conducted in 2018, the ratio of elephant carcasses to live animals was 14 percent. Now, it’s …

The United Nations reports that up to 222 million people globally are facing acute hunger — and that 47 million of them in the Greater Horn of Africa. Most parts of the region are battling the worst drought in 40 years. After four consecutive years of drought and a fifth season of failed rains looming, health experts fear great loss of life. A new World Health Organization analysis of seven countries in the region finds disease outbreaks and climate-related emergencies have reached their highest level this century. Analysts have recorded a total of 39 health emergencies this year in Djibouti, Ethiopia, Kenya, Somalia, South Sudan, Sudan, and Uganda. Egmond Evers, the WHO’s Incident Manager for Greater Horn of Africa Food Insecurity and Health, said the food insecurity crisis in the region also is a health crisis, and that these twin disasters are interrelated. “Malnourished people become sick more easily and sick people become malnourished more easily. The outcomes when disease and malnutrition are combined are much worse,” he said. “We know this because the combination of cholera and malnutrition, measles and malnutrition, common childhood diseases and malnutrition — there is more severe disease and more death. We know globally already that 45 percent of all child deaths are linked to malnutrition.” Evers said lack of food also leads to increased displacement. People who suffer from food insecurity, he said, leave their homes in search of something to eat. He notes this makes the region’s more than 18 million refugees and …

A landmark deal to allow grain exports from Ukraine, which was back on track Wednesday after being briefly suspended, has played a crucial role in easing a global food crisis sparked by the Russian invasion of Ukraine. Brokered by the United Nations and Turkey and signed by Moscow and Kyiv on July 22, the agreement established a protected sea corridor to allow grain shipments to resume for the first time since the fighting began in February Here is what we know about the deal, known as the Black Sea Grain Initiative: Why was it needed? When Russian troops attacked in late February, Moscow imposed a blockade on Ukraine’s Black Sea ports, halting all agricultural exports from one of the world’s breadbaskets. The move left 20 million metric tons of grain stranded in Ukraine’s ports, causing food prices to surge worldwide. Before the war, up to 90% of Ukraine’s wheat, corn and sunflower exports were transported by sea, mostly from Odesa, with many developing countries relying heavily on Kyiv for grain. Agricultural commodity prices were high before the war because of the post-COVID-19 economic recovery, but the conflict pushed the price of grains such as wheat and corn to levels unsustainable for countries dependent on their import, such as Egypt, Lebanon and Tunisia. What does the deal cover? The deal ensures the safe export of grain, foodstuffs and fertilizers, including ammonia, from three Black Sea ports in southwestern Ukraine: Odesa, Chornomorsk and Pivdennyi. The first grain ship to leave under the …

Europe has warmed more than twice as much as the rest of the world over the past three decades and has experienced the greatest temperature increase of any continent, according to a report by the World Meteorological Organization.  The report on the state of the climate in Europe follows a summer of extremes. A record-breaking heat wave scorched Britain, Alpine glaciers vanished at an unprecedented rate and a long-lasting marine heat wave cooked the waters of the Mediterranean.   “Europe presents a live picture of a warming world and reminds us that even well-prepared societies are not safe from impacts of extreme weather events,” WMO secretary-general Petteri Taalas said in a statement.   From 1991 to 2021, temperatures over Europe warmed at an average of 0.5 degree Celsius per decade, the report said, while the global average was just 0.2 degree C.  Last year, extreme weather events made worse by climate change — chiefly floods and storms — caused more than $50 billion worth of damage in Europe.  The reason Europe is warming faster than other continents has to do with the fact that a large part of the continent is in the sub-Arctic and Arctic — the fastest-warming region on Earth — as well as changes in climate feedbacks, scientists said.  For example, fewer clouds over Europe during the summer has meant that more sunlight and heat now reaches the continent, said Freja Vamborg, senior scientist with the Copernicus Climate Change Service.  Some scientists have called Europe a “heat wave hot …

The World Health Organization warned Wednesday that Ebola’s arrival in the Ugandan capital highlighted the high risk of further spread of the deadly virus, calling on neighboring countries to boost their preparedness.  Since Uganda’s health ministry first declared the outbreak on September 20, the country has registered more than 150 confirmed and probable cases, including 64 deaths, WHO said.  And since the deadly disease spread to Kampala last week, 17 cases have been confirmed there, WHO chief Tedros Adhanom Ghebreyesus told reporters.  “Although these cases are linked to known clusters, the very fact that there are cases in a densely populated city underscores the very real risk of further transmission,” he said, speaking from WHO headquarters in Geneva.  There is a “very urgent need for increased readiness in districts and surrounding countries,” he warned.  Ebola is spread through bodily fluids, with common symptoms being fever, vomiting, bleeding and diarrhea. It is fought through tracing, containing and quarantining. Outbreaks are difficult to contain, especially in urban environments.  “Ebola in a complex, urban city like Kampala is not easy, and we have to do everything possible to pull every chain of transmission,” WHO incident manager Abdi Mahamud told reporters.  Tedros said the U.N. health agency had on Tuesday released an additional $5.7 million from its contingency fund for emergencies, in addition to the $5 million previously released to address the Uganda crisis.  WHO, he said, was working closely with the Ugandan government and partners to respond to the outbreak and was calling …
