New study may have found how the Grand Canyon was formed
Published in Geology, the research links Arizona's Meteor Crater, formed 56,000 years ago, to the canyon's development.
The study hypothesises that the meteor impact triggered landslides that blocked the Colorado River, creating a paleolake within the canyon.
This theory explains the presence of 56,000-year-old driftwood and lake sediments found in Stanton's Cave, located 150 feet above the river.
The age of the driftwood matches the geologic age of the asteroid impact and the proposed landslide dam, supporting the connection.

Scientists discover new link between Mounjaro and BREAST cancer
Mounjaro could help slash the risk of breast cancer tumours developing, exciting new research has suggested. The game-changing weight loss jabs have ushered in a new era in the war on obesity, but have also been linked to other health benefits, such as reducing the risk of heart attacks, strokes and kidney disease. Now, scientists have discovered that tirzepatide—the ingredient behind Mounjaro—may 'significantly' slow the growth of breast cancer tumours. American scientists, who carried out the trial, said the findings on mice show the drugs have a 'beneficial impact' on women with the disease. However, they cautioned further research was necessary to confirm their findings. Researchers also didn't speculate why the drug, which belong to class of medications called GLP-1 agonists, might lower a patient's chances of cancer. It comes as breakthrough research in May revealed that GLP-1s could help ward off up to 14 types of cancer including breast. Studies have also suggested obesity is a major risk factor in breast cancer returning and weight loss could improve outcomes. The game-changing weight loss jabs have ushered in a new era in the war on obesity, but have also been linked to other health benefits, such as slashing the risk of heart attacks, strokes and kidney disease Amanda Kucinskas, a research fellow in obesity and breast cancer risk at the University of Michigan and study author, said: 'While it is very preliminary data, our studies in mice suggest that these new anti-obesity drugs may be a way to reduce obesity-associated breast cancer risk or improve outcomes. 'While these are very preliminary results, they suggest that this new anti-obesity drug may also have a beneficial impact on breast cancer outcomes,' In the study, researchers tracked 16 nine-week-old mice with breast cancer tumours who were fed a high-fat diet to induce obesity. At 32 weeks old—roughly middle age for a mouse—the obese animals were divided into two groups. One group received tirzepatide injections every other day for 16 weeks, and the other a placebo. Scientists then measured the mice's weight and tumour growth twice a week. They found mice on the medication lost around a fifth of their body weight—roughly the average weight lost by patients taking Mounjaro long term. The fat loss occurred mainly in adipose tissue, the body's fat-storing cells. Mice treated with tirzepatide also had significantly smaller tumors, the scientists said. There was a 'clear link' between lower body weight and smaller tumor size, while total fat mass was also 'strongly linked' to how large the tumors became, they added. However, they cautioned that exactly how tirzepatide slowed tumour growth was not yet understood and further tests, including in humans, would first be necessary. The findings were presented in full this week at ENDO 2025, the Endocrine Society's annual meeting in San Francisco. It comes as research presented at the American Society for Clinical Oncology (ASCO) annual conference in May suggested GLP-1s could slash the risk of 14 obesity-related cancer—including breast—for people with diabetes. US scientists found those on GLP-1s had a 7 per cent lower risk of developing an obesity-related cancer than patients on DDP-4 inhibitors, another diabetes medication. When other health benefits were factored in, these patients were also 8 per cent less likely to die over the 10-year period. In December, groundbreaking research presented at the San Antonio Breast Cancer Symposium also suggested the jabs could also help protect against breast cancer returning. One study of more than 1,000 patients by the University of Texas found obese patients who took the drugs for just over a year after finishing treatment on average had a 'significantly improved' chance of living longer. However, surprisingly, they also found patients taking hormone drugs such as tamoxifen—given to many women to stop breast cancer recurrence—gained weight, despite using the jabs. At the time, experts told MailOnline they were unsure why this happened. But they suggested it may be because hormone therapy typically causes patients to gain weight, meaning the jabs aren't able to work effectively. For these patients, 'we may need to go up to a higher dose', Professor Neil Iyengar, then an oncologist at the Memorial Sloan Kettering Cancer Centre, New York, said.

Study reveals true origin story of the Grand Canyon
The formation of the Grand Canyon may be tied to a meteor strike that created another astonishing Arizona feature hundreds of centuries ago, a new study suggests. While the stunning northern Arizona national park has become an iconic tourist attraction among nature-loving visitors, its history is not widely considered. In the past, the creation of the steep-sided canyon was mainly attributed to tectonic plate shifts and erosion from the Colorado River, according to the National Parks Service (NPS) . The Grand Canyon runs 277 miles along the river, which has been 'carving away rock for the past five to six million years,' the NPS wrote. But a new study by Geology published on Tuesday proposes a bold new theory that explains where that flooding may have came from. Researchers connected another Arizona geographical feature, the Meteor Crater to the Grand Canyon's formation. The Meteor Crater, located about 130 miles southeast of the Grand Canyon's South Rim, was formed more than 56,000 years ago by a large iron-nickel asteroid. The study hypothesizes that the impact triggered landslides in the Grand Canyon that accounted for a hefty portion of its shaping. These landslides supposedly blocked off the Colorado River and formed a 'paleolake,' which is ancient lake that no longer exists, in the canyon. A unanswered question about the canyon has been how and when driftwood ended up in Stanton's Cave, a formation within the national park, as the head of the cave is roughly 150 feet above the river. 'It would have required a 10-times bigger flood level than any flood that has happened in the past several thousand years,' one of the authors of the study, University of New Mexico Professor Karl Karlstrom wrote in a statement . Ultimately, researchers deemed that since all of these timelines appear to match up, the asteroid that created the massive crater also caused the landslide. The landslide led to the paleolake, which created a dam in the Colorado River. This dam allowed for water to build up and eventually cause surging floods that flooded caves in the canyon, causing further erosion.

Gabapentin users may face 85% higher cognitive impairment risk
Gabapentin is a medication that, in the United States, is approved to treat seizures and shingles-related neuralgia. It is also used off-label to treat other health issues, including low back pain. Past studies have also found that using gabapentin may increase a person's risk of developing cognitive impairment and dementia. A new study reports that people who receive six or more prescriptions of gabapentin for lower back pain are at a higher risk of developing dementia and mild cognitive found these risks were more than doubled in adults between the ages of 35 to 49 is a medication that is approved by the Food and Drug Administration (FDA) for the treatment of some epileptic seizures, moderate-to-severe restless legs syndrome, and postherpetic neuralgia, which is a nerve pain associated with shingles. Additionally, gabapentin is sometimes prescribed off-label for anxiety disorders, insomnia, hot flashes, alcohol use disorder, akathisia, diabetic peripheral neuropathy, and lower back pain. Like all medications, gabapentin has some potential side effects, including dizziness, tiredness, water retention, and dry mouth. Past studies have also found that using gabapentin may cause breathing difficulties, and may increase a person's risk of developing cognitive impairment and dementia. Now, a new study published in the journal Regional Anesthesia & Pain Medicine reports that people who receive six or more prescriptions of gabapentin for lower back pain are at a higher risk of developing dementia and mild cognitive impairment (MCI). Scientists also discovered these risks were more than doubled in adults between the ages of 35 to 49 How does it affect dementia, MCI risk?For this study, researchers analyzed data from more than 26,000 adults through the federated health research network selected participants who had a diagnosis of chronic pain, chronic pain syndrome, lumbar radiculopathy, and chronic low back pain. They also categorized study participants into different age groups: 18–64, 18–34, 35–49, 50–64, and 65 or older. Researchers assess 10-year outcomes on study participants to see what percentage developed dementia, generally, or specifically Alzheimer's disease, vascular dementia, or MCI. 'Currently, there is a discrepancy on whether taking gabapentin increases a patient's risk for developing dementia,' Nafis B. Eghrari, a 4th-year medical student at Case Western Reserve University School of Medicine in Cleveland, OH, and first author of this study, told Medical News Today.'Moreover, there lacks a strong understanding of how gabapentin impacts cognitive function and whether it contributes to neurodegenerative processes. Previous studies have shown mixed findings on this topic. Thus, we decided to explore this gap in the field,' explained Eghrari.6 or more gabapentin prescriptions linked to 85% higher MCI riskUpon analysis, researchers found that study participants who received six or more gabapentin prescriptions had a 29% higher risk of developing dementia, and an 85% greater chance of being diagnosed with MCI.'The significance of this finding is an association between gabapentin prescription and dementia on a nationwide level,' Eghrari explained. 'Though this does not imply causation, this warrants further investigation on the drug's long-term effects.''In terms of clinical significance, I recommend that physicians prescribing gabapentin for chronic pain perform cognitive exams on a regular basis when seeing patients,' he continued.'I'd also advise patients who are taking this drug to alert their physician if they notice any cognitive deficits, including confusion, poor memory, or slowed thinking,' said the doubled in 35–49-year-oldsEghrari and his team also discovered that when looking at participants by age groups, the risks for dementia more than doubled and more than tripled for MCI in people who were 35 to 49 years old. 'We were surprised to find this relatively higher risk in the non-elderly population,' Eghrari said.'These results indicate that gabapentin may have a greater cognitive impact on non-elderly individuals, as elderly individuals are already at risk for neurodegeneration due to their older age. This finding warrants further investigation into the underlying mechanism of how gabapentin may impact cognition.' – Nafis B. Eghrari'The key takeaway of this study is that patients prescribed gabapentin for chronic back pain should be closely monitored by their physician for cognitive decline,' he continued. 'Moreover, gabapentin should be prescribed with caution due to the associated risk of dementia/cognitive impairment.''We hope to carry this research forward and explore whether there is a true causative relationship between gabapentin and cognitive impairment,' Eghrari added. 'We also plan to investigate the underlying mechanisms of how the drug may impact cognition.'What are the drawbacks of large dataset studies?MNT had the opportunity to speak with Neel Anand, MD, MCh Orth, a board-certified orthopedic spine surgeon and director of the Cedars-Sinai Spine Center in Los Angeles, about this study. Anand, who was not involved in the research, commented that there are pros and cons to studies with big data sets as there are many variables and it is hard to determine the true causative little or no information was provided on any other illnesses participants may have had or other medications they were taking.'The best thing I would take from the study is […] [that] there's not a single drug without a side effect — they all have some issues,' Anand pointed out. 'So the answer is, if you're chronically going to take something, you better watch out — something's [potentially] going to go wrong somewhere.'Anand said the best way to prove anything is to take a cohort of study participants who take a specific medication and nothing else, and compare them to another cohort who does not take the medication. And researchers need to ensure that participants take the medication if it is prescribed to noted that, in some cases, patients do not follow the doctor's indications regarding prescription medication. 'Sometimes they do more, sometimes they'll take less,' Anand said. 'The only way to actually study [the real-life effects of long-term drug use] would be to literally take a thousand people and give them gabapentin and nothing else, and a thousand you don't, and then follow them over 5 years or more,' he he admitted that 'at least we can be cognizant' that there may be a heightened risk of dementia with prolonged gabapentin is 'a possibility that [doctors] needs to be aware [of] or at least counsel our patients [on] — that's fair,' Anand added.
