Students discover disturbing truth about their cafeteria meals and demand action: 'Younger generations … have to think about their future'

Yahoo01-05-2025

Students in the Houston Independent School District are challenging the area's choice of lunch trays.
According to the Houston Chronicle, a trio of fourth-grade students, Celine David, Maddie Wood, and Dora Cabarcas, are leading the charge against the district's single-use, Styrofoam lunch trays.
"We believe that HISD school district should provide schools with better, environmentally friendly, healthy and safer materials for our school cafeteria," Wood said.
Polystyrene is a serious problem for the environment; it contributes massively to the Earth's plastic pollution problem, as it sits in landfills for centuries because it doesn't fully decompose naturally. What it does do, though, is break apart, creating tiny particles of plastic that wind up in the environment, polluting the soil and waterways, and wreaking environmental havoc.
On top of that, while it can be an effective and food-safe material to make trays out of, hot or fatty foods can cause it to leach chemicals, making it far less safe.
These students aren't the only ones trying to find ways to combat plastic pollution. A company in Europe is trying to push for more recyclable plastics used in containers, while researchers in Japan are working on a biodegradable plastic that dissolves in salt water. And a Finnish company is exploring the possibility of making plastic using carbon capture technology.
The trio of students met with Houston ISD superintendent Mike Miles in early April and noted that switching to reusable or biodegradable trays would remove 22 million Styrofoam trays from landfills each year. They proposed several alternatives, including reusable plastic or bamboo trays, as well as trays made from sugar cane that could have a cheaper upfront cost.
"Older people might think, 'Oh, well, it doesn't really bother me if the world gets covered in trash, because I'm not going to be alive then,'" Cabarcas said. "But the younger generations, they have to think about their future and the future of younger generations, because they're still going to be alive on this planet for a long time to come."

Texas Man Gets First US Robotic Heart Transplant

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The first fully robotic heart transplant in the United States was performed at Baylor St. Luke's Medical Center in Houston in March this year, according to an announcement by the hospital released on Tuesday. Why It Matters According to News in Health, the monthly magazine of the federal National Institutes of Health, "robotic surgery can lead to less pain and blood loss, smaller scars, and quicker recovery" than traditional surgery. The publication also reported it can be associated with fewer complications. What To Know On Tuesday Baylor St. Luke's Medical Center said it had performed operation on March 15 on 45-year-old Tony Rosales Ibarra, a Lufkin man who had advanced heart failure. Robotic surgery is typically performed by a robotic arm, fitted with surgical instruments and a 3D camera, that is controlled by a surgeon via a joystick and foot pedals. The surgeon does not need to make any direct contact with the patient. The robots do not operate autonomously. The operation was conducted by cardiothoracic surgeon Dr Kenneth Liao who told the Houston Chronicle that there had not been any complications in Ibarra's recovery. Ibarra said he agreed to the procedure as "I want to live" after being told it could improve his recovery. According to the Houston Chronicle Baylor St. Luke's had been planning to conduct a fully robotic heart transplant for some time.

Baylor St. Luke's Medical Center They concluded Ibarra was the ideal patient as he had already spent four months in hospital, meaning a less-invasive procedure would speed up his recovery time, and had a large heart increasing the number of potential donors. Liao said he avoided performing a sternotomy, which involves cutting through the breastbone, instead making a five-inch cut above Ibarra's belly button then removing his old heart and implanting a new one via the abdomen. He commented: "If we can stay away from the breastbone, that's a huge advantage." Ibarra was admitted to Baylor St. Luke's in November 17 2024 after a 2022 stroke left him with heart failure. Earlier this month he was medically cleared to resume exercising and driving again. Newsweek contacted Baylor St. Luke's Medical Center for comment via email on Wednesday outside of regular office hours. Robotic surgery is becoming increasingly common and was described by Dr Majid Al Fayyadh, CEO of Saudi Arabia's King Faisal Specialist Hospital and Research Centre, as "the future of health care" in an article for Newsweek in April. The world's first fully robotic heart transplant took place in Saudi Arabia in 2024. The Jupiter Medical Center in Florida began performing robotic surgeries in 2010 and earlier this year completed its 10,000th operation using this technique. What People Are Saying Speaking to the Houston Chronicle Ibarra said: "I told the doctors 'Do what you've got to do to save me. restrictions. I want to live.' He added: "I didn't know I was going to be the first one. I'm amazed." Dr Liao said: "I think this will be the future, and will hopefully someday become the standard of practice." Baylor St. Luke's Medical Center President Dr Bradley T. Lembcke said: "This pinnacle in heart transplantation brings great pride to our hospital and adds to its legacy of medical achievements and caring for the most complex health conditions that only advanced health care systems can treat successfully." However robotic surgery is not without its critics. In October 2024 the Royal College of Surgeons of England published an article by Professor T.A. Rockall, a consultant general surgeon who described claims robotic surgery can improve efficiency as "ill-informed rhetoric." Rockall said: "Cash-strapped hospitals are spending large amounts of money on robotic technology that could clearly be better spent elsewhere." What Happens Next Medical experts expect fully robotic surgery will become increasingly common due to its advantages over traditional surgery in terms of patient recovery time and reduced complications.

What's the purpose of dreaming?

We all dream — but why? As with many mysteries of the mind, science doesn't have one neat answer. 'You'll get as many answers to the question 'What is the purpose of dreaming?' as there are dream psychologists,' says Deirdre Barrett, dream researcher at Harvard University and author of The Committee of Sleep. According to Austrian neurologist and founder of psychoanalysis Sigmund Freud, dreams offered vital clues to unresolved conflicts buried deep within our psyche. But Freud's theory, introduced in his 1899 book The Interpretation of Dreams, sparked plenty of controversy. Critics argued that his dream interpretations were overly focused on sex, highly subjective, and impossible to verify—two analysts might offer entirely different readings of the same dream, with no objective way to know who was right. In the decades since Freud, other scientists have offered alternative explanations for why we dream. One of the most prominent is the threat simulation theory, proposed by Finnish neuroscientist and psychologist Antti Revonsuo in 2000. According to this view, dreaming is an ancient biological defense mechanism. By simulating dangerous situations, our brains rehearse the skills needed to recognize and avoid threats—a kind of virtual reality training ground for survival. A 2005 study lent support to this theory by examining the dreams of Kurdish children exposed to war and trauma. Compared to non-traumatized Finnish children, these children reported more frequent dreams filled with severe threats, suggesting that their minds were practicing how to cope with danger. But even the threat simulation theory is debated. A 2008 study comparing residents of high-crime areas in South Africa to those in low-crime parts of Wales found that South African participants, despite facing more real-world threats, actually reported fewer threatening dreams than their Welsh counterparts. This result challenges the idea that the brain uses dreams to simulate danger when exposed to trauma. Can tracking make my sleep worse? The quiet torment of sleep tech. Why do some people need less sleep? Poor sleep can make you more susceptible to conspiracy theories How to fix your sleep schedule without pulling an all-nighter 5 reasons you can't sleep Another theory suggests that dreams are simply a side effect of memory consolidation—the brain's way of replaying and reinforcing new memories while we sleep. As the brain's hippocampus and neocortex work together to file away fresh information, they may also blend it with older memories, creating the often strange mashups we experience as dreams. Dreams may also help us process and manage emotions, especially negative ones, according to the emotion regulation theory of dreaming. Research focusing on recently divorced individuals experiencing depression found that participants who dreamed about their ex-spouses were more likely to show significant improvement in their mood one year later, particularly if their dreams were vivid and emotionally rich. Another study found that people who dreamed about stressful events they had experienced before sleep woke up feeling more positively about the events the next day, suggesting that dreams can help transform emotional distress into resilience. Recent brain imaging studies support this idea. People who frequently experience fear-related dreams show reduced activation in fear centers of the brain during waking life, hinting that these dreams may serve as a kind of overnight therapy session, helping us better regulate our emotions when awake. Ultimately, Barrett suggests that we may be asking the wrong question. 'We'd rarely ask the analogous question: 'What is the purpose of thinking?'' she says. Just as waking thought serves many functions—from planning to problem-solving to daydreaming—dreams likely do too. 'The value of dreaming lies in its difference. It's a distinct mode of thought—one that supplements and enriches our waking cognition.' In fact, some researchers believe dreams offer a unique mental space for solving problems that stump us during the day. In this altered brain state, regions responsible for imagery become more active, allowing the mind to solve problems requiring visualisation. History is full of famous examples: Mary Shelley reportedly dreamed the central scenes of Frankenstein; German chemist August Kekulé envisioned the ring structure of benzene in a dream; and Russian chemist Dmitri Mendeleev dreamed his final form of the periodic table of the elements. In the end, dreams may serve many purposes—or none at all—but they remind us that even in sleep, the brain never truly rests.
