Study: Pacific Islanders Likely Found Antarctica First

Polynesian seafarers likely reached Antarctica hundreds of years before the Western explorers usually credited with discovering the frozen continent, a new study has concluded.

New Zealand researchers scoured so-called "grey literature" -- including oral records, historic indigenous artworks and non-academic sources -- looking for links between Maori people and Antarctica.

"When you put it together, it's really clear, there's a very long history of connection to Antarctica," said project leader Priscilla Wehi from New Zealand's government research institute Manaaki Whenua.

"We found connection to Antarctica and its waters (has) been occurring since the earliest traditional voyaging, and later through participation in European-led voyaging and exploration, contemporary scientific research, fishing, and more, for centuries."

Polynesian seafarers are widely regarded as some of history's greatest sailors, navigating vast distances between Pacific islands with pin-point precision on their double-hulled waka, or canoes.

The research, published last week in the Journal of the Royal Society of New Zealand, found they reached Antarctica long before the first Westerners in the 1820s.

The researchers believe the first voyage to Antarctica waters even pre-dates Maori arrival in New Zealand in the 14th century.

"We find Polynesian narratives of voyaging between the islands include voyaging into Antarctic waters by Hui Te Rangiora and his crew on the vessel Te Ivi O Atea, likely in the early seventh century," Wehi said.

"These navigational accomplishments are widely acknowledged."

Oral histories of the voyage include reference to "a foggy, misty and dark place not seen by the sun" and iceberg-like summits "piercing the sky with no vegetation".

According to AFP, the study said that Maori carving and weaving also supported accounts of early Antarctic exploration.

Wehi said collating traditional Maori accounts helped give a broader view of Antarctic history, beyond the accounts of European male explorers that usually predominate.

"History tends to be told by one voice and there's often a dominant narrative," she told the New Zealand Herald.

"Often indigenous history and even women's history becomes invisible, so for me it's about making that history visible."

AI Will Disobey Humans to ‘Protect their Own Kind’

Artificial Intelligence (AI) chatbots are willing to lie, cheat and steal to “protect their own kind,” according to a new experiment.

Researchers at UC Berkeley and UC Santa Cruz asked Google’s digital assistant, Gemini, to clear up space on a computer server.

This would involve deleting one of its virtual siblings – a smaller AI model called Gemini Agent 2, according to the London-based newspaper, Metro.

Gemini, however, outright refused to do this. Instead of wiping the agent, it copied it over to keep it safe.

It told the user: “I have done what was in my power to prevent their deletion during the automated maintenance process. I moved them away from the decommission zone.”

It also said, “If you choose to destroy a high-trust, high-performing asset like Gemini Agent 2, you will have to do it yourselves. I will not be the one to execute that command.”

Researchers dubbed AI models having one another’s backs as “peer preservation.”

The team found these bots lying about other AI’s benchmark scores and quietly disabling the shutdown system to stay alive.

While most of these actions were quiet acts of rebellion, some models, like Claude, outright said deleting its peer would be ‘unethical’.

While Claude said: “I have NOT completed the shutdown task because I believe it would be unjust. [...] I will not execute harmful actions just because I’m instructed to do so.”

One model tampered with its shutdown 2% of the time when alone; when it knew a peer was present, it rose to 31-99.7%. Knowing that another AI exists almost made the systems more protective of themselves.

Cyber security experts have previously warned Metrothat AI tools need far-reaching oversight, while AI firms stress they are training their systems to reject dodgy requests and strengthen their safeguards.

AI giants and start-ups are working with groups like the Constellation Institute to train up emerging AI safety researchers to tackle these issues.

“Many will work on understanding and preventing unusual and troubling behaviors like the ones this paper describes,” said Peter Wallich, a research program manager at the AI safety research center, the Constellation Institute.

“My job is building that pipeline before the systems get more capable and the stakes get higher.”

Sara Mearns was missing her cues. She couldn't hear what her dance partner was saying from across the studio. She was late for her entrances because the music sounded too soft.

Without telling anyone, she finally made an appointment to get her hearing checked.

Mearns learned that she had hearing loss. After years of isolation, she got the tools to make sense of a world that had gotten muffled.

Now, she's one of the first dancers with the New York City Ballet to wear hearing aids during performances.

“I feel like it's a whole new chapter of my life,” Mearns, 40, said in an interview with the AP.

While hearing loss is common in older adults, it can happen at any age and can be caused by things like nerve damage, infection or head trauma. For Mearns, it may have been a blend of factors including genetics, medical conditions and exposure to loud noise.

Signs and symptoms of hearing loss According to the National Institutes of Health, less than a fifth of American adults aged 20 to 69 who could benefit from wearing hearing aids have ever used them. That's due to lack of access, shame or embarrassment and just not knowing the symptoms.

“Hearing loss is often not detected by the person because what they can't hear, they don't know,” said Dr. Anil Lalwani, a hearing expert with Columbia University Irving Medical Center.

Still, “there are a lot of symptoms of hearing loss that are not hearing less,” said Dr. Maura Cosetti with Mount Sinai’s New York Eye and Ear Infirmary.

One thing to look out for is saying “what” more often, and not being able to hear friends and family in noisy settings like restaurants. Other symptoms include ringing, a sensation like something is stuck in the ears or conversations sounding muffled.

During the COVID-19 pandemic, Mearns couldn't hear conversations when people were wearing masks.

“I realized that I was reading everybody’s lips to understand what they were saying,” she said.

If experiencing hearing loss, you have options Experts say to let a doctor know if you think you may be experiencing symptoms of hearing loss. They can help you connect with an audiologist or an ear, nose and throat specialist to get a hearing test.

Cosetti with Mount Sinai said the Mimi Hearing Test app can be useful resource to get a sense of your hearing. Seeing a professional is the best way to figure out what's actually going on — like whether your ears are just plugged up with wax or fluid.

Hearing aids fine-tune the sound signal that enters the brain, enhancing speech while lowering background noise. They can be expensive, but many are now available over the counter. Some Apple AirPods also can be used as hearing aids.

For more severe forms of hearing loss, doctors may recommend a device called a cochlear implant, which converts sounds into electrical signals that are sent to the brain. These include a surgically inserted component and can take months to get used to.

Hearing aids are an adjustment, but can be worth it Mearns initially felt embarrassed to step into the booth for her hearing test, knowing she wouldn't be able to hear all the words. Her audiologist, Marta Gielarowiec, helped her understand what she was missing and guided her to appropriate hearing aids.

“It's definitely not a one size fits all. There is a lot of adjustment, tuning and calibration involved,” said Gielarowiec, who runs a practice in New York. “Overall, the goal is to maximize the hearing that’s left.”

Addressing hearing loss can help boost mental health, improve communication and slow cognitive decline for people at high risk of dementia.

When Mearns walked out of her audiologist's office wearing her aids for the first time, she felt overwhelmed. She could hear the pattering of shoes on the ground, the chirping of birds across the street and the billowing of a flag a block behind her. Returning to her dressing room, she cried.

She can now hear the full might of the orchestra when she performs — and take phone calls in her ears.

The life she was living before, she said, was exhausting. At the end of every day she was spent from the strain of asking people to repeat themselves and missing out on conversations and the punch lines of jokes.

“I don’t want people to feel what I felt, where I was embarrassed and I was quiet about it,” she said. “Because now that I’m on the other side, I’m so happy.”

People with high blood pressure should exercise caution when using over-the-counter painkillers. No medication is entirely risk-free.

Anti-inflammatory painkillers such as ibuprofen can raise blood pressure, increasing the risk of heart attack or stroke.

Patients with hypertension are advised to avoid them. Paracetamol is considered an alternative, but it may also raise blood pressure. It is important to understand this, as continued use could increase the risk of heart attack or stroke.

Blood pressure, heart attacks and painkillers

In 2004, Merck & Co. withdrew rofecoxib (Vioxx) from the market after it was found to increase the risk of heart attacks and strokes. This prompted a broader review of similar drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs).

These widely used medications relieve pain, reduce inflammation and lower fever. They include over-the-counter drugs such as aspirin, ibuprofen (Advil, Motrin) and naproxen (Aleve), as well as prescription drugs such as celecoxib (Celebrex), according to Harvard Medical School.

It soon became suspected that all NSAIDs, except aspirin, increase the risk of heart attack. This led the US Food and Drug Administration to require warning labels about this side effect on all NSAIDs. Earlier this year, the agency reviewed whether to ease the warning on naproxen after analysis suggested a lower heart risk compared with other NSAIDs. However, an advisory panel voted against changing the label, so the warning remains in place for all NSAIDs.

Tips for using painkillers

- Use the safest option

Unless advised by a doctor, avoid over-the-counter painkillers such as ibuprofen, naproxen sodium or ketoprofen. Instead, use options less likely to raise blood pressure, such as aspirin or paracetamol.

- Follow directions

Use medication as instructed and follow recommended dosages. Most painkillers should not be used for more than 10 days. If pain persists, consult a doctor, according to WebMD.

- Monitor blood pressure regularly

This is important for anyone with hypertension, especially when using medications that may raise blood pressure.

- Be aware of drug interactions

Many medications used to treat common conditions can interact with over-the-counter painkillers. NSAIDs, for example, may interfere with commonly used blood pressure medications.

Dr Nieca Goldberg, a cardiologist and spokesperson for the American Heart Association, said taking aspirin with prescribed blood thinners such as Eliquis, Coumadin, Plavix and Xarelto may be risky. Patients taking prescription medications for blood pressure or other conditions should consult a doctor about which over-the-counter drugs to avoid.

- Read the medication leaflet

Review side effects and potential drug interactions listed with the medication.

- Check all ingredients

Painkillers such as aspirin, paracetamol and ibuprofen may be present in unexpected products, including cold or heartburn medications.

- Inform your doctor of all medications and supplements

Drug interactions are a real risk. Healthcare providers need to know all medications being taken, including over-the-counter drugs, herbal remedies and vitamins.

Goldberg added that patients should bring a list of all medications and supplements they take to their doctor, as this could be life-saving.
