Eliminating cancer cells that survive KRAS inhibition: A potential way to prevent relapse
Our cells rely on tightly regulated signaling pathways to control when they grow, divide and survive. When these regulatory systems are disrupted, cells can acquire the ability to grow uncontrollably and become cancerous. One of the most important cancer-related signaling molecul
First 3D views of human cone opsins reveal how daylight vision reacts so fast
First 3D views of human cone opsins reveal how daylight vision reacts so fast
The retina of the human eye contains 6–7 million cone cells. These cells contain light-sensitive proteins known as cone opsins. They enable us to perceive our surroundings in detail in daylight. They allow us to see the world in thousands of colors: red strawberries, green leaves
Leveraging AI can reduce time and resources in how physicians approach sepsis care
In a new clinical study from the University of California San Diego School of Medicine, researchers and physicians at UC San Diego Health have found that by utilizing artificial intelligence (AI), they could develop more timely and efficient assessments of care provided to patien

Construction sites are not ready for extreme heat: 44% of workers said they have experienc
Hot weather is already having a negative impact on U.K. construction workers' health and well-being, and most construction sites are not set up to protect them, researchers have found.

Charting palliative care priorities to recognize and support caregivers
Unpaid caregivers need greater recognition and support to continue the care they provide to their families and friends, and researchers have identified priorities outlining how to achieve this. Flinders University's Research Center for Palliative Care, Death and Dying has publish

New Alzheimer's drugs offer hope for some, but good dementia care protects the humanity of
Disease-modifying drugs for Alzheimer's offer a meaningful glimpse of hope for many people who fear dementia. Alzheimer's disease is the most common cause of dementia, but dementia itself is an umbrella term for symptoms such as memory loss, confusion and changes in thinking.
Blood vessel cells keep fixed signaling roles for weeks, reshaping view of capillary commu
Blood vessel cells keep fixed signaling roles for weeks, reshaping view of capillary commu
The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have known about this signaling for decades. What they didn't know, until now, is that
AI-guided microneedles bend at body temperature to speed diabetic wound healing
Chronic wounds remain a major health care challenge, especially for people with diabetes, who often experience delayed healing, persistent inflammation and a higher risk of infection. Traditional wound-closure methods such as sutures, staples and adhesives can help bring wound ed
Researchers develop HIV-prevention guide without the stigma of asking about risk
Researchers develop HIV-prevention guide without the stigma of asking about risk
The most useful thing about a new HIV prevention guide may be a question it never asks: Why do you want to know about pre-exposure prophylaxis, or PrEP? In a pilot study at three clinics, a two-page decision aid helped people choose between a daily pill, long used to prevent HIV,
Heat waves can leave homes dangerously hot, even for young, healthy adults
Heat waves can leave homes dangerously hot, even for young, healthy adults
Most people know that heat waves can be dangerous. What they may not realize is that the heat indoors can be much worse than outdoors.

Researchers discover a cause of neuron excitability in ALS, suggesting a new potential tre
Digging deep into the molecular mechanisms behind ALS, researchers at the Les Turner ALS Center at Northwestern Medicine have discovered why nerve cells overfire in the disease. Not only that—they have also designed a new drug to stop this overfiring, which could potentially slow

Survey finds 3 in 10 young adults don't have a doctor; if they do, most don't see them
A new survey commissioned by The Ohio State University Wexner Medical Center finds young adults are missing out on the health benefits of having a primary care doctor.
