California’s governor flew in for the young bears’ debut. Throngs of media gathered inside the zoo, while the city of San Diego warned of traffic jams ahead of the much-anticipated event Thursday.

The San Diego Zoo rolled out the red carpet for the first public showing of its celebrity residents, who were already dressed in black-and-white attire. The two giant pandas, the first to enter the US in two decades, seemed unfazed by all the attention, sunbathing and chowing down on bamboo in their new home.

For years, the Chinese government has loaned pandas to zoos around the world in a practice called “panda diplomacy.” These fuzzy ambassadors have long been a symbol of the US-China friendship, ever since Beijing gifted a pair of pandas to the National Zoo in Washington, DC, in 1972.

But in recent years, China stopped renewing panda loans to zoos and calling back home the animals it had given to Western countries as relations soured. The San Diego Zoo’s previous pandas left in 2018 and 2019.

Then in February, the China Wildlife Conservation Association announced it was sending two more pandas to San Diego and also signing agreements with the zoo in the Spanish capital of Madrid, quelling fears that Beijing was ending its historic panda diplomacy. San Diego's pandas arrived in June and have been acclimating to their new home before being seen by the public.

“This is about something much deeper, much richer, than just the two beautiful pandas we celebrate,” Gov. Gavin Newsom said at the opening ceremony that included dancing, music, and remarks from Chinese ambassador Xie Feng, and other local officials. “It’s about celebrating our common humanity.”

For the occasion, Newsom proclaimed Aug. 8 as California Panda Day and recognized the San Diego Zoo as the first organization in the US to establish a cooperative panda conservation program with China.

Xie said he met someone on his flight who had traveled all the way from Washington, DC, to see the pandas.

“Two little panda fans from California wrote several letters to me proposing giving China grizzly bears to get pandas,” Xie said, eliciting laughs.

Only four other giant pandas currently reside in the United States, all at the zoo in Atlanta. However, the Smithsonian’s National Zoo will receive a new pair of pandas by the end of the year after its last bears returned to China last November. As part of the loan agreement, US zoos typically pay $1 million a year toward China’s wildfire conservation efforts, and all cubs born in the US must return to China by age 4.

Both pandas at the San Diego Zoo were born at the Wolong Shenshuping Panda Base in China’s Sichuan province.

Yun Chuan is a nearly five-year-old male panda described by the zoo as “mild-mannered, gentle and lovable.” He is the grandson of Bai Yun and Gao Gao, who both lived at the San Diego Zoo for more than a decade. His mother, Zhen Zhen, was the fourth cub born at the zoo.

Xin Bao is a nearly four-year-old female panda described by the zoo as a “gentle and witty introvert with a sweet round face and big ears.”

“Her name means a treasure of prosperity and abundance, and we hope she will bring you good luck,” Ambassador Xie said. He also spoke about China being California’s top trading partner as well as the large Chinese community in the state and the abundance of Chinese tourists.

Among the pandas' biggest fans are two kids who were proudly wearing “Panda Ridge” t-shirts and carrying plushies at the zoo Thursday morning.

“Pandas are their favorite animals, if you could only see what our house looks like in terms of stuffed animals,” their father James Metz said.

It was also his seven-year-old daughter's birthday, making it an extra special occasion. For weeks, the family has been eagerly watching live panda feeds from China in anticipation of the bears' arrival.

Yun Chuan and Xin Bao were hanging out and relaxing after eating, Metz said.

A portrait of one of the panda's grandmothers, who lived at the zoo for more than 20 years, was created by California-based artist Shepard Fairey, who is best known for designing the “Hope” imagery in former President Barack Obama’s 2008 campaign.

Australian firefighters warned people on Monday to prepare for more bushfires in a "high-risk" summer, after blazes killed one person and incinerated more than 350 buildings in the southeast.

Weather conditions have eased since strong winds and temperatures topping 40C fed dozens of wildfires in southeastern Australia's Victoria, which declared a state of disaster on Saturday.

But officials said 12 major fires were still burning across the state.

Country Fire Authority chief officer Jason Heffernan said another "heating event" was expected towards the end of January, though its intensity was uncertain.

"We are early in the high-risk weather season," Heffernan told a news conference.

"There's been a lot of fire in the landscape. Much work will be done between now and then to contain these fires," he said.

"Whilst we join with community in the rebuilding and the relief and recovery of the fires that have been, we need to turn our minds to the fires that could be as the season continues."

More than 350 structures -- including over 65 homes -- have been lost so far in the state, officials said, with the number likely to rise as fire damage is assessed.

One person died in a fire near the town of Longwood, about two hours' drive north of state capital Melbourne, police say.

Emergency Management Commissioner Tim Wiebusch said weather conditions had become more favorable for firefighters.

"But that doesn't mean that the risk is over," he said.

"Whilst the conditions are easing in some parts of the state, even the slightest of winds are still causing those fires to move around."

High temperatures and dry winds combined last week to form some of the most dangerous bushfire conditions since the "Black Summer" blazes.

The Black Summer bushfires raged across Australia's eastern seaboard from late 2019 to early 2020, razing millions of hectares, destroying thousands of homes and blanketing cities in noxious smoke.

Australia's climate has warmed by an average of 1.51C since 1910, researchers have found, fueling increasingly frequent extreme weather patterns over both land and sea.

Some Supplements Can Make Your Medication Less Effective

Health experts warned that some supplements can interact with certain medications and reduce their effectiveness, according to Eating Well website.

While these supplements are usually sold over-the-counter, taking them without asking a health care provider can have dangerous impact on your health.

Naturopathic doctor Jacob Wolf said that for instance, some vitamin and mineral supplements can interfere with absorption of medications.

Other supplements can bind with medications, preventing the drug from being utilized in the body, or they may be metabolized by the same or similar pathways as medications, explains Wolf. That can have a dangerous impact on your health.

Top offenders include calcium, magnesium, iron, fiber, activated charcoal and vitamins C and K.

Minerals like calcium, magnesium and iron can bind with medications, especially levothyroxine, a drug used to treat hypothyroidism, said Wolf.

“This can impact how levothyroxine is utilized in the body, adversely affecting treatment,” he explained.

These minerals can also interact with antibiotics in the tetracycline and fluoroquinolone class, said pharmacist Amanda Corbett.

Taking these mineral supplements at the same time as antibiotics may reduce the bioavailability of the antibiotic, creating risks like bacterial resistance or ineffective treatment.

And while scientists affirm fiber is an important nutrient for digestive regularity, healthy cholesterol levels and blood sugar management, supplementing isn’t always a great idea, as large doses can impact the absorption of certain medications.

Fiber-rich foods are a cornerstone of blood sugar management, even for those taking blood sugar–lowering medications, like metformin.

Fiber may also impair the effectiveness of other drugs, including digoxin (which treats certain heart conditions) and levothyroxine for hypothyroidism, Wolf said.

Therefore, if you do choose to take a fiber supplement, Wolf recommended speaking with your health care provider about spacing out your fiber and medication doses.

As for activated charcoal, it is a form of carbon that is used in the emergency room to treat the ingestion of toxic drugs and poisons.

“Activated charcoal acts like a sponge and can bind to many medications. It is best to completely avoid activated charcoal if on any life-critical medication,” said Wolf.

For Vitamin C, it is an important antioxidant that protects cells from free radical damage and supports proper immune system function.

However, if you are undergoing chemotherapy treatment for cancer, experts strongly caution against taking vitamin C supplements.

“Vitamin C can lead to certain chemotherapies being less effective or ineffective in treating cancer,” said Corbett.

Vitamin E, another antioxidant, can also interfere with chemotherapy’s effectiveness.

If taking Vitamin K, which is a fat-soluble vitamin that helps blood clot and shores up bone health, you should know that it can reduce the effectiveness of a blood-thinning medication called warfarin (Coumadin).

That, in turn, can make blood more likely to clot, which can lead to a heart attack or stroke.

If you are taking warfarin, you don’t necessarily need to avoid vitamin K, but it is critical to keep the amount you consume—from both foods and supplements—consistent to avoid clotting problems.

Experts advise that to take supplements safely, consult with your health care provider.

Many supplements can interact with medications, and so it’s critical to connect with your prescribing health care provider to make sure that the supplements you’re taking play nice with your medications.

Also, look for those that have been independently tested in a laboratory, recommended Corbett.

Experts say you should also know how much to take. Supplement dosages are listed on the label, but they aren’t standardized.

That means they can vary from product to product, and may far exceed safe levels.

 

 

 


Rejuvenated Human Eggs… Scientists Revolutionize IVF Success

Rejuvenated Human Eggs… Scientists Revolutionize IVF Success

German scientists claim to have “rejuvenated” human eggs for the first time in an advance that they predict could revolutionize IVF success rates for older women.

The groundbreaking research suggests that an age-related defect that causes genetic errors in embryos could be reversed by supplementing eggs with a crucial protein, according to The Guardian.

When eggs donated by fertility patients were given microinjections of the protein, they were almost half as likely to show the defect compared with untreated eggs.

If confirmed in more extensive trials, the approach has the potential to improve egg quality, which is the primary cause of IVF failure and miscarriage in older women.

The decline in egg quality is the main reason IVF success rates drop steeply with female age and is why the risk of chromosome disorders such as Down’s syndrome increases with maternal age.

“Overall we can nearly halve the number of eggs with [abnormal] chromosomes. That’s a very prominent improvement,” said Prof Melina Schuh, a director at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and a co-founder of Ovo Labs, which is aiming to commercialize the technique.

“Most women in their early 40s do have eggs, but nearly all of the eggs have incorrect chromosome numbers,” added Schuh, whose lab has been investigating egg biology for the past two decades. “This was the motivation for wanting to address this problem.”

The latest approach targets a vulnerability in eggs linked to a process called meiosis, in which sex cells (eggs or sperm) jettison half their genetic material so they can join together to make an embryo.

In eggs, this requires 23 pairs of X-shaped chromosomes to align along a single axis in the cell. On fertilization, the cell divides causing the chromosome pairs to be – ideally – neatly snapped down their centers to create a cell with precisely 23 single chromosomes from the mother, the rest being delivered by the sperm.

However, in older eggs the chromosome pairs tend to loosen at their midpoint, becoming slightly unstuck or detaching entirely before fertilization.

In this scenario, the X-shaped structures fail to line up properly and move around chaotically in the cell, so when the cell divides they are not snapped symmetrically.

This results in an embryo with too many or too few chromosomes.

Schuh and colleagues previously found that a protein, Shugoshin 1, which appears to act as a glue for the chromosome pairs, declines with age. In the latest experiments in mouse and human eggs, they found that microinjections of Shugoshin 1 appeared to reverse the problem of chromosome pairs separating prematurely.

Using eggs donated by patients at the Bourn Hall fertility clinic in Cambridge, they found that the number showing the defect decreased from 53% in control eggs to 29% in treated eggs. When they looked only at eggs from women over 35 years of age, a similar trend was seen (65% compared with 44%), although this result was not statistically significant, which the scientists said was probably due to them only having treated nine eggs in this age range.

Dr Agata Zielinska, a co-founder and co-CEO of Ovo Labs, said: “Currently, when it comes to female factor infertility, the only solution that’s available to most patients is trying IVF multiple times so that, cumulatively, your likelihood of success increases. What we envision is that many more women would be able to conceive within a single IVF cycle.”

The findings will be presented at the British Fertility Conference in Edinburgh on Friday and have been published as a preprint paper on the Biorxiv website.
