Not undergoing traditional cancer therapy, such as that of Elle Macpherson, poses significant risks

Supermodel Elle Macpherson refuses chemotherapy to treat breast cancer

Australian Press Agency/Alamy

Half of us will develop cancer at some point in our lives, but how many of us can confidently reject mainstream medical advice after consulting dozens of doctors?

In a recent interview Australian Women's Weekly Australian supermodel Elle Macpherson revealed that she did just that, telling the magazine that she was diagnosed with breast cancer seven years ago but refused chemotherapy, opting for an “intuitive, heart-led, holistic approach” to her treatment.

According to the magazine, MacPherson mulled over her decision for weeks after consulting with “32 doctors and specialists,” and finally, in February 2017, she decided to pursue non-pharmaceutical treatment under the guidance of her family doctor, who specializes in “integrative medicine.”

Fortunately, MacPherson is currently in clinical remission, or as she prefers to say, “perfect health.” It's futile to try to assess the risk of her decision to forego chemotherapy without knowing important details about the extent of her cancer, her coexisting risk factors, and the advice she received. For example, she underwent a partial mastectomy, her first surgery to remove a suspicious lump, but Some doctors said That might have been enough treatment.

Nevertheless, the story has sparked outrage online, galvanizing both the growing number of people who distrust “conventional medicine” and those who seek to defend it from growing attacks.

What's behind this distrust? Some researchers say the COVID-19 pandemic “Scientific skepticism” Heated debates are taking place around the world about the severity of the illness, the merits of lockdowns, and the safety of vaccines. More and more Used To hide their anti-scientific views, Conspiracy thinking.

For members of black and minority ethnic communities, Distrust of doctors The reluctance to seek cancer testing and treatment is also being driven by public health and medical institutions. Decades of failure Engaging with them and ensuring equal care in many countries.

In the UK in particular, confidence in the National Health Service's ability to treat cancer has declined. Has fallen in recent yearsand Reports Delaying the start of vital cancer treatment for months.

All of this means that if you're diagnosed with cancer today, your options may seem less clear than they once were. Add to that the typically grueling experience of chemotherapy, and it's no wonder that MacPherson's story of a “non-pharmaceutical” alternative therapy has garnered so much attention.

But it's worth keeping in mind that MacPherson doesn't accurately represent the vast majority of cancer patients. Estimated Net Worth With a net worth of $95 million, she can afford to seek multiple second opinions and even turn down chemotherapy. Her wealth acts as a safety net. Her “ingestible health” company WELCOand her historical romantic ties Disgraced anti-vaxxer Andrew Wakefield,she From 2018 to 2019McPherson's story gets even more complicated.

For most people, refusing medical care carries real risks. 2017 Study Cancer patients who choose alternative medicines as their primary treatment have been found to have a higher risk of dying within five years than those who choose conventional treatments.

Larger studies The following year, he published a study of nearly two million American cancer patients that found that use of complementary medicines was associated with refusal of conventional cancer treatment and a doubling of the risk of death within five years.

Indeed, oncologists More and more Select Use Reduce chemotherapy or avoid it altogether – New treatments, new research The recognition that targeted, customized responses are most effective.

But for now, at least, the advice from organisations like Cancer Research UK is clear: there is no scientific or medical evidence that alternative therapies can cure cancer. At a time when distrust of medicine is widespread, Macpherson's account risks leading people down a dangerous path by trumpeting positive results without important context.

While anyone may be at risk for developing cancer, Macpherson, who was nicknamed “The Body” at the height of her modeling career, had enormous resources at her disposal and was always going to have a better chance than most of us of surviving cancer, regardless of her choices.

EPA Institutes Ban on Pesticides that Pose Risks to Unborn Babies

The Environmental Protection Agency announced on Tuesday that an emergency order has been issued. This action is the first of its kind in almost four decades and aims to halt the use of pesticides that may harm unborn babies.

The herbicide in question, dimethyltetrachloroterephthalate (DCPA or Dacthal), is commonly used to control weeds in various crops like broccoli, onions, kale, Brussels sprouts, cabbage, and strawberries.

Exposure to this chemical during pregnancy can lead to changes in thyroid hormone levels in the fetus, which could result in long-term negative impacts such as low birth weight, impaired brain development, lower IQ, and diminished motor skills later in life, according to the EPA.

This risk prompted the EPA to take decisive action and suspend the use of the pesticide. Michal Friedhoff, deputy director of the Office for Chemical Safety and Pollution Prevention, stated, “DCPA is extremely dangerous and needs to be removed from the market immediately.” The agency emphasized this in a statement.

The emergency order is now in effect.

Friedhoff further emphasized the EPA’s role in safeguarding the public from hazardous chemicals, saying, “In this case, a pregnant woman who unknowingly encounters DCPA could give birth to a child with irreversible health issues.”

The DCPA has been banned in the European Union since 2009.

Miri Treviño Sauceda, executive director of the National Farmers Union, praised the EPA’s decision as “historic.”

The suspension follows years of dialogue between the EPA and AMVAC Chemical Corporation, the sole manufacturer of DCPA.

The company has not responded to requests for comment.

In 2013, the EPA requested data from AMVAC on the herbicide’s health effects, specifically requesting comprehensive studies on DCPA’s impact on thyroid development. Despite receiving multiple studies from AMVAC between 2013 and 2021, the EPA found the data inadequate and did not accept certain requests, including the thyroid study, until it was finally submitted in August 2022.

The EPA’s recent assessment of DCPA was part of a routine process to reassess registered pesticides. Inspections occur every 15 years to ensure there are no adverse health effects or environmental hazards.

California facing increased heat and fire risks leading up to Fourth of July weekend

California is bracing for a dangerous combination of extreme heat and high fire risk this week as people across the state celebrate Independence Day outdoors. Temperatures in the Sacramento Valley could soar to 115 degrees Fahrenheit, according to meteorologist Kate Forrest from the National Weather Service in Sacramento. Heat warnings have been issued for the region starting Tuesday and are expected to last through Saturday.

Forecasters anticipate the heat wave to start in inland California on Tuesday before spreading to the Pacific Northwest and Southern California later in the week. Heat watches, warnings, and advisories will be in effect across the West on Tuesday from southern Oregon to southeastern California’s low desert according to the National Weather Service.

The increase in temperatures is due to a strong high-pressure system lingering in the region. Governor Gavin Newsom has instructed emergency officials to activate the state’s operations center in response to the upcoming heatwave.

The hot weather could see nighttime temperatures exceed 80 degrees Fahrenheit in some areas, with inland California facing “extreme” conditions by Friday, as indicated on the Heat Risk Map from the Centers for Disease Control and Prevention and the National Weather Service.

Southern Oregon, including the Medford area, is also under a heat watch through Saturday. Meanwhile, Pacific Gas & Electric has warned of potential power outages in 10 California counties on Tuesday due to high winds and dry conditions.

Given the high temperatures and dry conditions, there is an increased risk of wildfires, prompting caution during Fourth of July celebrations involving fireworks. The California Department of Forestry and Fire Protection is monitoring 13 active fires in the state.

Climate change has been linked to the increased frequency and intensity of heat waves and wildfires. Analysis from Climate Central shows that regions like the Sacramento Valley are experiencing more fire-prone weather compared to previous decades.

With heat waves growing in frequency and duration, it is important for residents to take precautions to stay safe during extreme weather events.

Medical records of astronauts uncover health risks of space travel

How spaceflight affects astronauts' health may be better understood thanks to the creation of the first “space-omics” biobank, a collection of thousands of blood and tissue samples and medical information taken on multiple space missions.

These include missions to the International Space Station as well as SpaceX's Inspiration 4, the first private spaceflight to send four non-government-trained astronauts into space for three days in 2021.

The resource, called the Space Omics and Medical Atlas (SOMA), contains detailed medical data, collectively known as biomarkers, such as DNA damage and changes in people's gene activity and immune system function.

Space flight is known to pose certain health risks. For example, astronauts experience reduced bone density and muscle mass due to weightlessness, and high levels of radiation in space can damage cells and DNA, causing a variety of health effects on the body. Astronauts are more likely to develop heart disease Later years and Some people have experienced a decrease in vision After going into space.

By consistently collecting astronauts' medical data through the SOMA biobank, researchers may be able to better understand these changes and develop ways to mitigate them, the researchers say. Christopher Mason He is a professor at Weill Cornell Medicine in New York and helped establish the biobank.

“Biomarkers don't necessarily translate into anything clinically meaningful, but they're a good way to understand how this unique environment is affecting us.” Damien Bailey The researchers are from the University of South Wales in the UK, but were not involved in the study.

One of the findings from the Inspiration 4 mission was that although astronauts experienced changes in numerous biomarkers, most measurements returned to normal within a few months of returning to Earth.

This suggests that sending private citizens into space poses no greater health risks than sending professional astronauts, Mason said. “Instead of training them for decades, we can start opening up space to more people.”

Results from Inspiration 4, which had two men and two women on board, also suggested that changes in gene activity returned to normal more quickly in women. This may be because women's bodies have to be able to cope with the possibility of pregnancy, Mason says. “Being able to withstand big changes in physiology and fluid dynamics could be great for managing pregnancy, but it could also help manage the stresses of spaceflight.”

Timothy Etheridge A researcher from the University of Exeter in the UK says it would be beneficial to have a common resource that researchers around the world can use. “We need a consistent approach to collecting samples,” he says.

Thomas Smith The researcher, from King's College London, says understanding the health effects of spaceflight will become even more important if longer-term missions take place, such as trips to Mars. “Anything that leads to longer-term missions makes it even more important to know what's going on and, ideally, to be able to address it,” he says.

AI Industry Faces Risks, Employees from OpenAI and Google DeepMind Sound Alarm

A group of current and former employees from prominent artificial intelligence companies has published an open letter. The committee warned of inadequate safety oversight within the industry and called for better protection for whistleblowers.

The letter, advocating for a “right to warn about artificial intelligence,” is a rare public statement about the risks of AI from employees in a usually secretive industry. It was signed by 11 current and former employees of OpenAI and two current and former Google DeepMind employees, one of whom previously worked at Anthropic.

“AI companies have valuable non-public information about their systems’ capabilities, limitations, safeguards, and risk of harm. However, they have minimal obligations to share this information with governments and none with the public. We cannot rely on companies to share this information voluntarily,” the letter stated.

OpenAI defended its practices, stating that they have hotlines and mechanisms for issue reporting, and they do not release new technology without proper safeguards. Google did not respond immediately to a comment request.

Concerns about the potential dangers of artificial intelligence have been around for years, but the recent AI boom has heightened these concerns, leading regulators to struggle to keep up with technological advancements. While AI companies claim to be developing their technology safely, researchers and employees warn about a lack of oversight to prevent AI tools from exacerbating existing societal harms or creating new ones.

The letter also mentions a bill seeking to enhance protections for AI company employees who raise safety concerns. The bill calls for transparency and accountability principles, including not forcing employees to sign agreements that prevent them from discussing risk-related AI issues publicly.

In a recent report, it was revealed that companies like OpenAI have tactics to discourage employees from freely discussing their work, with consequences for those who speak out. OpenAI CEO Sam Altman apologized for these practices and promised changes to exit procedures.

The open letter echoes concerns raised by former top OpenAI employees about the company’s lack of transparency in its operations. It comes after recent resignations of key OpenAI employees over disagreements about the company’s safety culture.

US corporations will be required to disclose climate-related risks to the public

Companies will now be required to disclose information on how climate change could impact their financial performance, although not as detailed as initially proposed.

The Securities and Exchange Commission recently approved new climate risk disclosure rules, a significant change that mandates companies to include details about their emissions and other important risks they face in their public disclosures.

While some critics argue that the rules have been diluted due to pressure from business leaders, others believe this is an opportunity for investors to better understand the economic risks associated with climate change.

The new rules, approved by a 3-2 vote, require large publicly traded companies to disclose some aspects of their carbon footprint and how climate change could impact their business. Compared to the initial draft, the final rules apply to fewer companies and do not require disclosure of most indirect carbon emissions.

Many large companies already voluntarily disclose this information, and experts believe that the new rules could help reduce greenwashing, establish a common disclosure standard, and improve transparency for investors.

The adoption of these rules reflects a growing recognition within the business community about the economic risks of climate change, shifting from a previously abstract issue to a tangible threat that requires regulatory attention.

According to Cynthia Hanawalt, from Columbia University’s Sabin Center on Climate Change Law, the rules represent a significant step towards standardizing information for investors and enhancing transparency regarding the risks posed by climate change.

The rules were proposed in 2022 and have faced significant scrutiny, resulting in a final version that excludes the disclosure of Scope 3 emissions, which are indirect emissions associated with a company’s supply chain and product use.

As the rules are phased in, only large companies with a market value of at least $75 million will be required to disclose their emissions information, potentially impacting sectors such as automotive, agriculture, and cement.

Despite the limitations of the final rules, experts believe that they will set a new standard for climate risk disclosure globally and influence expectations in capital markets.

While the rules have been praised for promoting transparency and accountability, they may face legal and political challenges from groups seeking stricter disclosure requirements and opponents of such regulations.

Overall, the new rules aim to help companies manage their climate and emissions goals, prevent greenwashing, and provide investors with crucial information about the risks associated with climate change.

Legal challenges are anticipated, and resolution could take years, as the SEC works to address concerns from both sides of the debate.

Unveiling the unexpected potential and serious risks of AI feigning empathy

It has been 100 days since the war in Gaza began, and it has become increasingly difficult to read the news. Her husband told me it might be time to talk to a therapist. Instead, on a cold winter morning, after fighting back tears as I read another tale of human tragedy, I turned to artificial intelligence.

“I’m pretty depressed about the state of the world,” I typed into ChatGPT. “It’s natural to feel overwhelmed,” the magazine responded, offering a list of practical advice, including limiting media exposure, focusing on the positive and practicing self-care.

I closed the chat. I was sure that I would benefit from doing all this, but at that moment I didn’t feel much better.

It may seem strange that an AI would even try to provide this kind of assistance. But millions of people have already turned to his ChatGPT, a professional therapy chatbot that provides convenient and inexpensive mental health support. Even doctors are said to be using AI to create more empathetic notes for patients.

Some experts say this is a boon. After all, AI may be able to express empathy more openly and tirelessly than humans, unhindered by shame or burnout. “We admire empathetic AI” by a group of psychological researchers I wrote recently.

But others are not so sure. Many people question the idea that AI can be empathetic and worry about the consequences if people seek emotional support from machines that can only pretend to care. Some even wonder if the rise of so-called empathic AI might change the way we think…

The Risks and Health Benefits of Cold Water Swimming

Immersing your body in cold water stimulates the release of an invigorating cocktail of chemicals.

“It's like pressing Control-Alt-Del on your computer,” says Cath Pendleton. “When I'm in the water, I get so focused on my body that my brain switches off. It's just swimming with me.”

Pendleton, an ice swimmer based in Merthyr Tydfil, England, is as tough as anyone. In 2020, five years after she realized she didn't mind swimming in very cold water, she became the first person to swim one mile inside the Antarctic Circle. Part of her training included sitting in a freezer in a shed.

But she's not the only one passionate about cold water. Rivers, lakes, and oceans that were once home to a handful of serious year-round swimmers are now on the verge of extinction, thanks to media reports about the mental health impact of frigid dips and pool closures due to COVID-19. The number of people visiting is rapidly increasing. An estimated 7.5 million people swim outdoors in the UK alone, and more and more people swim outdoors during the winter. Global numbers are hard to come by, but the International Winter Swimming Association is seeing a boom in winter swimmer registrations around the world, including in China, Russia and Finland, where water temperatures can drop below 0C.

But what could be better than the joy of being in nature and the perverted feeling of happiness that defies the cold? According to the latest research, the answer is probably: Recent studies are beginning to uncover evidence that cold water immersion can reduce stress and depression, and may help deal with autoimmune diseases.
