The good news: You will get a glorious extra hour of sleep. The bad: It’ll be dark by late afternoon for the next few months in the United States.

Daylight saving time ends at 2 a.m. local time Sunday, which means you should set your clock back an hour before you go to bed. Standard time will last until March 9, when we will again “spring forward” with the return of daylight saving time. 

“Fall back” should be easier. But it still may take a while to adjust your sleep habits, not to mention the downsides of leaving work in the dark or trying to exercise while there’s still enough light. Some people with seasonal affective disorder, a type of depression usually linked to the shorter days and less sunlight of fall and winter, may struggle, too. 

Some health groups, including the American Medical Association and American Academy of Sleep Medicine, have said it’s time to do away with time switches and that sticking with standard time aligns better with the sun — and human biology. 

Two states — Arizona and Hawaii — don’t change and stay on standard time. 

Here’s what to know about the twice-yearly ritual. 

How the body reacts to light 

The brain has a master clock that is set by exposure to sunlight and darkness. This circadian rhythm is a roughly 24-hour cycle that determines when we become sleepy and when we’re more alert. The patterns change with age, one reason that early-to-rise youngsters evolve into hard-to-wake teens. 

Morning light resets the rhythm. By evening, levels of a hormone called melatonin begin to surge, triggering drowsiness. Too much light in the evening — that extra hour from daylight saving time — delays that surge and the cycle gets out of sync. 

How do time changes affect sleep? 

Even an hour change on the clock can throw off sleep schedules — because even though the clocks change, work and school start times stay the same. 

That’s a problem because so many people are already sleep deprived. About 1 in 3 U.S. adults sleep less than the recommended seven-plus hours nightly, and more than half of U.S. teens don’t get the recommended eight-plus hours on weeknights. 

How to prepare for the time change 

Some people try to prepare for a time change jolt by changing their bedtimes little by little in the days before the change. There are ways to ease the adjustment, including getting more sunshine to help reset your circadian rhythm for healthful sleep.

CALI, Colombia — After two weeks of negotiations, delegates on Saturday agreed at the United Nations conference on biodiversity to establish a subsidiary body that will include Indigenous peoples in future decisions on nature conservation, a development that builds on a growing movement to recognize the role of the descendants of some regions’ original inhabitants in protecting land and combating climate change. 

The delegates also agreed to oblige major corporations to share the financial benefits of research when using natural genetic resources. 

Indigenous delegations erupted into cheers and tears after the historic decision to create the subsidiary body was announced. It recognizes and protects the traditional knowledge systems of Indigenous peoples and local communities for the benefit of global and national biodiversity management, said Sushil Raj, Executive Director of the Rights and Communities Global Program at the Wildlife Conservation Society. 

“It strengthens representation, coordination, inclusive decision making, and creates a space for dialogue with parties to the COP,” Raj told The Associated Press, also known as the Conference of Parties. 

Negotiators had struggled to find common ground on some key issues in the final week but came to a consensus after talks went late into Friday. 

‘Historical debt’ 

The COP16 summit, hosted in Cali, Colombia, was a follow-up to the historic 2022 accord in Montreal, which included 23 measures to save Earth’s plant and animal life, including putting 30% of the planet and 30% of degraded ecosystems under protection by 2030. 

A measure to recognize the importance of the role of people of African descent in the protection of nature was also adopted in Cali. 

The Indigenous body will be formed by two co-chairs elected by COP: one nominated by U.N. parties of the regional group, and the other nominated by representatives of Indigenous peoples and local communities, the AP saw in the final document. 

At least one of the co-chairs will be selected from a developing country, taking into account gender balance, the document said. 

“With this decision, the value of the traditional knowledge of indigenous peoples, Afro-descendants and local communities is recognized, and a 26-year-old historical debt in the Convention on Biological Diversity [CBD] is settled,” Susana Muhamad, Colombia’s environment minister and COP16 president, posted on social media platform X shortly after the announcement. 

Who owns nature’s DNA was one of the most contentious and fiercely negotiated topics at the summit as tensions spiked between poorer and developed countries over digital sequence information on genetic resources, or DSI. 

Negotiators consented on Saturday morning, however, to bind big companies to share benefits when using resources from animals, plants or microorganisms in biotechnologies. 

Delegations agreed on a genetic information fee of 0.1% of companies’ revenues from products derived from such information. 

“Many of the life-saving medicines we use today come from the rainforest. It is therefore right that a portion of the income companies generate from this information goes back to protect nature,” said Toerris Jaeger, executive director of Rainforest Foundation Norway. “This is the absolute highlight from COP16.” 

Needs exceed pledges

Also adopted was an agreement to protect human health from Earth’s increasing biodiversity issues. Ecosystem degradation and loss of ecological integrity directly threaten human and animal health, environmental groups say. 

Pledges made by countries during the two weeks were far short of the billions needed to tackle plummeting global biodiversity, with only around $400 million in the fund. 

The modest pledges don’t bode well for the next U.N. climate talks, COP29, to take place in Azerbaijan beginning later this month. COP29 is expected to focus on how to generate trillions of dollars needed for the world to transition to clean energies such as solar, wind and geothermal. Raising that money will require major commitments by nations, companies and philanthropies. 

In Montreal’s biodiversity summit, wealthy nations pledged to raise $20 billion in annual conservation financing for developing nations by 2025, with that number rising to $30 billion annually by 2030. 

Global wildlife populations have plunged on average by 73% in 50 years, according to the World Wildlife Fund and the Zoological Society of London biennial Living Planet report in October.

TOKYO — A remote-controlled robot has safely returned with a tiny piece of melted fuel it collected from inside one of three damaged reactors at the tsunami-hit Fukushima Daiichi nuclear power plant for the first time since the 2011 meltdown.

Tokyo Electric Power Company Holdings, which manages the plant, said Saturday that the extendable fishing rod-like robot successfully clipped a gravel as big as 5 millimeters, the size of a tiny granola bit, from the top surface of a mound of molten fuel debris that sits on the bottom of the No. 2 reactor’s primary containment vessel.

The Telesco robot, with its frontal tongs still holding the melted fuel bit, returned to the enclosed container for safe storage after workers in full hazmat gear pulled it out of the containment vessel earlier Saturday.

The sample marks the first time that melted fuel has been retrieved out of the containment vessel. But the mission is not over until it’s certain that the sample’s radioactivity is below a set standard and safely placed into a container.

If the radioactivity exceeds the limit, the robot must go back inside the reactor to find another piece. TEPCO officials said they expect the piece is small enough to meet the requirement.

The mission initially started in August for what was supposed to be a two-week round trip but had been suspended twice due to mishaps.

The first one was the procedural mistake at the beginning that held up the work for nearly three weeks. Then the robot’s two cameras, designed to transmit views of the target areas for its operators in the remote-control room, failed. The camera problem required the robot to be pulled out all the way for replacement before the mission resumed Monday.

Fukushima Daiichi lost its key cooling systems during the 2011 earthquake and tsunami, causing meltdowns in its three reactors. An estimated 880 tons of fatally radioactive molten fuel remains in them, and TEPCO has carried out a number of robotic probes to figure out how to decommission the plant.

Telesco on Wednesday successfully clipped a piece presumably measuring less than 3 grams (0.1 ounce) from the planned area right underneath the Unit 2 reactor core, from which large amounts of melted fuel fell during the meltdown 13 years ago, TEPCO said.

Plant chief Akira Ono said only the tiny spec can provide key data to plan decommissioning strategy, develop necessary technology and robots and retroactively learn how the accident developed.

The government and TEPCO have set a 30-to-40-year target for the cleanup, which experts say is overly optimistic and should be updated.

No specific plan for the full removal of the fuel debris or its final disposal has been decided.

As winter approaches and daylight hours grow shorter, people prone to seasonal depression can feel it in their bodies and brains.

“It’s a feeling of panic, fear, anxiety and dread all in one,” said Germaine Pataki, 63, of Saskatoon, Saskatchewan.

She’s among the millions of people estimated to have seasonal affective disorder, or SAD. Her coping strategies include yoga, walking and an antidepressant medication. She’s also part of a Facebook group for people with SAD.

“I try to focus on helping others through it,” Pataki said. “This gives me purpose.”

People with SAD typically have episodes of depression that begin in the fall and ease in the spring or summer. Changing the clocks back to standard time, which happens this weekend, can be a trigger for SAD. A milder form, subsyndromal SAD, is recognized by medical experts, and there’s also a summer variety of seasonal depression, though less is known about it.

In 1984, a team led by Dr. Norman Rosenthal, then a researcher at the National Institutes of Health, first described SAD and coined the term. “I believe that because it is easy to remember, the acronym has stuck,” he said.

What causes seasonal affective disorder?

Scientists are learning how specialized cells in our eyes turn the blue wavelength part of the light spectrum into neural signals affecting mood and alertness.

Sunlight is loaded with the blue light, so when the cells absorb it, our brains’ alertness centers are activated and we feel more wakeful and possibly even happier.

Researcher Kathryn Roecklein at the University of Pittsburgh tested people with and without SAD to see how their eyes reacted to blue light. As a group, people with SAD were less sensitive to blue light than others, especially during winter months. That suggests a cause for wintertime depression.

“In the winter, when the light levels drop, that combined with a lower sensitivity, might be too low for healthy functioning, leading to depression,” Roecklein said.

Miriam Cherry, 50, of Larchmont, New York, said she spent the summer planning how she would deal with her winter depression. “It’s like clockwork,” Cherry said. “The sunlight is low. The day ends at 4:45, and suddenly my mood is horrible.”

Does light therapy help?

Many people with SAD respond to light therapy, said Dr. Paul Desan of Yale University’s Winter Depression Research Clinic.

“The first thing to try is light,” Desan said. “When we get patients on exposure to bright light for a half an hour or so every morning, the majority of patients get dramatically better. We don’t even need medications.”

The therapy involves devices that emit light about 20 times brighter than regular indoor light.

Research supports using a light that’s about 10,000 lux, a measure of brightness. You need to use it for 30 minutes every morning, according to the research. Desan said this can help not only people with SAD but also those with less-severe winter blahs.

Special lights run from $70 to $400. Some products marketed for SAD are too dim to do much good, Desan said.

Yale has tested products and offers a list of recommendations, and the nonprofit Center for Environmental Therapeutics has a consumer guide to selecting a light.

If your doctor diagnosed you with SAD, check with your insurance company to see if the cost of a light might be covered, Desan suggested.

What about talk therapy or medication?

Antidepressant medications are a first-line treatment for SAD, along with light therapy. Doctors also recommend keeping a regular sleep schedule and walking outside, even on cloudy days.

Light therapy’s benefits can fade when people stop using it. One type of talk therapy — cognitive behavioral therapy, or CBT — has been shown in studies to have more durable effects, University of Vermont researcher Kelly Rohan said.

CBT involves working with a therapist to identify and modify unhelpful thoughts.

“A very common thought that people have is ‘I hate winter,'” Rohan said. “Reframe that into something as simple is ‘I prefer summer to winter,'” she suggested. “It’s a factual statement, but it has a neutral effect on mood.”

Working with a therapist can help people take small steps toward having fun again, Rohan said. Try planning undemanding but enjoyable activities to break out of hibernation mode, which “could be as simple as meeting a friend for coffee,” Rohan said.

What else might work?

People with SAD have half the year to create coping strategies, and some have found hacks that work for them — though there may be scant scientific support.

Elizabeth Wescott, 69, of Folsom, California, believes contrast showers help her. It’s a water therapy borrowed from sports medicine that involves alternating hot and cold water while taking a shower. She also uses a light box and takes an antidepressant.

“I’m always looking for new tools,” Wescott said.

Cherry in New York is devoting a corner of her garden to the earliest blooming flowers: snowdrops, winter aconite and hellebores. These bloom as early as February.

“That’s going to be a sign to me that this isn’t going to last forever,” Cherry said. “It will get better, and spring is on its way.”

sydney — A 5.48-meter Australian crocodile that held the world record as the largest crocodile in captivity has died, a wildlife sanctuary said on Saturday. He was thought to be more than 110 years old.

Cassius, weighing in at more than one ton, had been in declining health since October 15, Marineland Melanesia Crocodile Habitat said on Facebook.

“He was very old and believed to be living beyond the years of a wild croc,” according to a post by the organization, based on Green Island near the Queensland tourist town of Cairns.

“Cassius will be deeply missed, but our love and memories of him will remain in our hearts forever.”

The group’s website said he had lived at the sanctuary since 1987 after being transported from the neighboring Northern Territory, where crocodiles are a key part of the region’s tourist industry.

Cassius, a saltwater crocodile, held the Guinness World Records title as the world’s largest crocodile in captivity.

He took the title after the 2013 death of Philippines crocodile Lolong, who measured 6.17 meters long, according to Guinness.

A regional public health department in Idaho is no longer providing COVID-19 vaccinations to residents in six counties after a narrow decision by its board.

Southwest District Health appears to be the first in the nation to be restricted from giving COVID-19 shots. Vaccinations are an essential function of a public health department.

While policymakers in Texas banned health departments from promoting COVID-19 vaccines and Florida’s surgeon general bucked medical consensus to recommend against the vaccine, governmental bodies across the country haven’t blocked the vaccines outright.

“I’m not aware of anything else like this,” said Adriane Casalotti, chief of government and public affairs for the National Association of County and City Health Officials. She said health departments have stopped offering the vaccine because of cost or low demand, but not based on “a judgment of the medical product itself.”

The six-county district along the Idaho-Oregon border includes three counties in the Boise metropolitan area. Demand for COVID-19 vaccines in the health district has declined — with 1,601 given in 2021 to 64 so far in 2024. The same is true for other vaccines: Idaho has the highest childhood vaccination exemption rate in the nation, and last year, the Southwest District Health Department rushed to contain a rare measles outbreak that sickened 10.

On Oct. 22, the health department’s board voted 4-3 in favor of the ban — despite Southwest’s medical director testifying to the vaccine’s necessity.

“Our request of the board is that we would be able to carry and offer those [vaccines], recognizing that we always have these discussions of risks and benefits,” Dr. Perry Jansen said at the meeting. “This is not a blind, everybody-gets-a-shot approach. This is a thoughtful approach.”

Opposite Jansen’s plea were more than 290 public comments, many of which called for an end to vaccine mandates or taxpayer funding of the vaccines, neither of which are happening in the district. At the meeting, many people who spoke are nationally known for making the rounds to testify against COVID-19 vaccines, including Dr. Peter McCullough, a Texas cardiologist who sells “contagion emergency kits” that include ivermectin and hydroxychloroquine — drugs that have not been approved to treat COVID-19 and can have dangerous side effects.

Board Chairman Kelly Aberasturi was familiar with many of the voices who wanted the ban, especially from earlier local protests of pandemic measures.

Aberasturi, who told The Associated Press that he’s skeptical of COVID-19 vaccines and national public health leaders, said in the meeting and in an interview with the AP that he was supportive of but “disappointed” in the board’s decision.

He said the board had overstepped the relationship between patients and their doctors — and possibly opened a door to blocking other vaccines or treatments.

Board members in favor of the decision argued people can get vaccinated elsewhere, and that providing the shots was equivalent to signing off on their safety. (Some people may be reluctant to get vaccinated or boosted because of misinformation about the shots despite evidence that they’re safe and have saved millions of lives.)

The people getting vaccinated at the health department — including people without housing, people who are homebound and those in long-term care facilities or in the immigration process — had no other options, Jansen and Aberasturi said.

“I’ve been homeless in my lifetime, so I understand how difficult it can be when you’re … trying to get by and get ahead,” Aberasturi said. “This is where we should be stepping in and helping.

“But we have some board members who have never been there, so they don’t understand what it’s like.”

State health officials have said that they “recommend that people consider the COVID-19 vaccine.” Idaho health department spokesperson AJ McWhorter declined to comment on “public health district business,” but noted that COVID-19 vaccines are still available at community health centers for people who are uninsured.

Aberasturi said he plans to ask at the next board meeting if the health department can at least be allowed to vaccinate older patients and residents of long-term care facilities, adding that the board is supposed to be caring for the “health and well-being” of the district’s residents. “But I believe the way we went about this thing is we didn’t do that due diligence.”

geneva — More than 50,000 people have so far been vaccinated against mpox in the Democratic Republic of Congo and Rwanda, the World Health Organization’s chief said on Friday.

The outbreak is still not under control, the African Union’s health watchdog warned a day earlier, appealing for resources to avoid a “more severe” pandemic than Covid-19.

More than 1,100 people have died of mpox in Africa, where some 48,000 cases have been recorded since January, according to the Africa Centres for Disease Control and Prevention (Africa CDC).

The majority of deaths have been in the DRC, the epicenter of the outbreak, which launched a vaccination drive last month.

“So far, more than 50,000 people have been vaccinated against mpox in the Democratic Republic of Congo and Rwanda, thanks to donations from the United States and the European Commission,” WHO Director-General Tedros Adhanom Ghebreyesus told reporters.

He also said that nearly 900,000 vaccine doses had this week been allocated to nine countries under a mechanism set up by the WHO and its partners.

The countries in question were to be informed on Friday, he added.

“This is the first allocation of almost six million vaccine doses that we expect to be available by the end of 2024” through the Access and Allocation Mechanism (AAM), the WHO chief said.

Mpox, previously known as monkeypox, is caused by a virus transmitted to humans by infected animals that can also be passed from human to human through close physical contact.

Related to smallpox, the viral disease causes fever, body aches, swollen lymph nodes and a rash that forms into blisters.

NEW DELHI — A thick layer of toxic smog cloaked India’s capital on Friday as smoke from firecrackers used to celebrate Diwali, the Hindu festival of lights, pushed air pollution to hazardous levels.

New Delhi’s air quality index plunged into the “severe” category, according to SAFAR, India’s main environmental monitoring agency. In many areas, levels of deadly particulate matter reached seven times the World Health Organization’s safety limit.

Authorities in the capital have banned the use and sale of traditional firecrackers since 2017, asking people to opt for environmentally friendly ones or light shows instead, but the rule is often flouted.

New Delhi, home to more than 33 million people, is regularly ranked one of the most polluted cities in the world.

The air pollution crisis deepens particularly in the winter when the burning of crop residue in neighboring states coincides with cooler temperatures that trap deadly smoke. That smoke travels to New Delhi, leading to a surge in pollution and worsening the public health crisis.

Emissions from industries without pollution controls and the use of coal, which produces most of the country’s electricity, are also linked to poor air quality in urban areas.

“We may not realize it now, but later we will face lung problems,” said Manoj Kumar, a New Delhi resident who does his morning runs around the capital’s iconic India Gate monument.

Several studies have estimated that more than a million Indians die each year from air pollution-related diseases. Tiny particulate matter in polluted air can lodge deep in the lungs and cause a variety of major health problems.

Bird flu has infected three more people from Washington state after they were exposed to poultry that tested positive for the virus, according to health authorities in Washington and in Oregon, where the human cases were identified. 

A total of 39 people have tested positive for bird flu in the U.S. this year, including nine from Washington, as the virus has infected poultry flocks and spread to more than 400 dairy herds, federal data show. All of the cases were farm workers who had known contact with infected animals, except for one person in Missouri. 

The people from Washington cleaned facilities at an infected chicken farm after birds were culled to contain the virus, the Washington State Department of Health said in an email on Thursday. 

Officials tested workers who had symptoms, including red eyes and respiratory issues, and those with potential exposure to the birds, the department said. People with symptoms were told to isolate and given antiviral treatment, it added. 

Oregon identified the three new cases after the people traveled to the state from Washington while infected, the Oregon Health Authority said in a Thursday statement. They have since returned to Washington, where public health staff are monitoring them, according to the statement. 

There have been no infections among people living in Oregon and there is no evidence of human-to-human transmission, the Oregon Health Authority said. It said the risk for infection to the general public remains low. 

Since 2022, the virus has wiped out more than 100 million poultry birds in the nation’s worst-ever bird flu outbreak. 

H5N1 bird flu was confirmed in a pig on a backyard farm in Oregon, the first detection of the virus in swine in the country, the U.S. Department of Agriculture said on Wednesday.

The United Nations, scientists and governments made an urgent call Wednesday for increased funding to protect coral reefs under threat of extinction.

Research this year shows that 77% of the world’s reefs are affected by bleaching, mainly due to warming ocean waters amid human-caused climate change. It’s the largest and fourth mass global bleaching on record and is impacting both hemispheres, United Nations Capital Development Fund said.

The findings prompted a U.N. special emergency session — typically called to address escalating conflicts or natural disasters — on corals to be convened on sidelines of the U.N. biodiversity summit, known as COP16, nearing its end after two weeks in Cali, Colombia.

Coral reefs are vital ecosystems that support over 25% of marine life and nearly a billion people, many relying on reefs for food security, coastal protection and livelihoods, the U.N. development fund said.

After the emergency session, the governments of New Zealand, the United Kingdom, Germany and France made new pledges totaling around $30 million to the U.N. fund for coral reefs established in 2020. By 2030, the fund seeks to leverage up to $3 billion in public and private finance to support coral reef conservation efforts. Around $225 million has been raised to date.

“Protecting our ocean and its precious habitats is fundamental to life on earth,” said U.K. Minister for Nature Mary Creagh. “But without urgent action, the world’s coral reefs face extinction from global heating, acidification, disease, and pollution; a vital ecosystem lost within our lifetime.”

Next year, a U.N. ocean conference will take place in Nice, France, and countries are being urged beforehand to pledge more to the U.N. global fund for coral reefs with the aim of mobilizing an additional $150 million in donations by the conference.

“In 2024, climate change and other human impacts triggered the fourth mass coral reef bleaching event, the most extensive and devastating on record,” said Peter Thomson, the U.N. Secretary-General’s Special Envoy for the Ocean. “With the window to protect these ecosystems closing rapidly, world leaders must act now.”

“We must secure a sustainable future for coral reefs and the countless lives that rely on them —before it’s too late,” Thomson said.

A change in water temperature can cause coral to drive out algae that provides nutrition, lose its color and become stressed. Coral may bleach for other reasons, such as extremely low tides, pollution or too much sunlight.

In the world’s largest coral reef ecosystem, Australia’s Great Barrier Reef, bleaching affected 90% of the coral assessed in 2022. The Florida Coral Reef, the third-largest, experienced significant bleaching last year.

The first mass bleaching happened in 1998, the second between 2011-2013, the third in 2016, said Kenyan marine ecologist David Obura, who heads Coastal Oceans Research and Development in the Indian Ocean East Africa.

“They’re lasting more than one year at a time, which is worrying,” Obura said at the U.N. emergency session at COP16.
