ヒ素への曝露と米の消費 - それらすべての中で最も有毒な穀物

Researchers at USF Health have discovered a new way opioid receptors can work that may lead to safer pain medications. Their findings show that certain experimental compounds can amplify pain relief without intensifying dangerous side effects like suppressed breathing. This research offers a fresh blueprint for designing opioids that last longer, work better, and pose fewer risks. It also opens doors to safer treatments for other brain disorders.

Many people with multiple sclerosis struggle with balance and coordination, and this study uncovers a hidden reason why. Researchers found that inflammation in the brain disrupts the energy supply of vital movement-controlling neurons. As their mitochondria fail, these cells weaken and eventually die, worsening motor problems over time. Protecting brain energy systems could open the door to slowing these symptoms.

Scientists have found that combining silybin with carvedilol works far better against liver fibrosis than either drug alone. The duo targets the root drivers of liver scarring, sharply reducing collagen buildup and liver damage in experimental models. Importantly, both drugs are already approved and commonly prescribed. That makes this discovery especially promising for rapid clinical translation.

Scientists have uncovered a surprising viral shortcut that turns moving cells into delivery vehicles for infection. Instead of spreading one virus at a time, infected cells bundle viral material into large structures called Migrions and pass them directly to new cells. This collective delivery jump-starts viral replication and boosts disease severity. The finding reveals a migration-based route of viral spread that defies classic models of infection.

A long-running debate over Tamiflu’s safety in children may finally be settled. Researchers found that influenza, not the antiviral medication, was linked to serious neuropsychiatric events like seizures and hallucinations. Even more striking, kids treated with Tamiflu had about half the risk of these events compared to untreated children with the flu. The results suggest the drug may be protective rather than harmful.

Nearly all women in STEM graduate programs report feeling like impostors, despite strong evidence of success. This mindset leads many to dismiss their achievements as luck and fear being “found out.” Research links impostorism to worse mental health, higher burnout, and increased thoughts of dropping out. Supportive environments and shifting beliefs about intelligence may help break the cycle.

The idea that we make over 200 unconscious food choices a day has been repeated for years, but new research shows the number is more illusion than insight. The famous figure comes from a counting method that unintentionally exaggerates how many decisions people really make. Researchers warn that framing eating as mostly “mindless” can undermine confidence and self-control. A more realistic view focuses on meaningful choices—and practical strategies that make healthy decisions easier.
