Medical Xpress / How T cells amplify signals: New study reveals key molecular switch
Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be precisely amplified to mount an effective defense against invasive threats. New research by immunologists ...
Phys.org / Should wildlife parks be fenced? We studied 60 African examples for an answer
Fences are among conservation's most controversial interventions. To some, they are essential for conserving wildlife, minimizing encroachment, and preventing the type of conflict that happens when humans come into contact ...
Medical Xpress / About 80% of breast cancer biopsies turn out benign. New imaging tool promises clearer diagnoses and fewer biopsies
Ultrasound is widely used in breast cancer diagnosis. While it can effectively show that a lump is filled with fluid—indicating it is unlikely to be cancer—it cannot reliably determine whether a solid mass is benign or cancerous. ...
Medical Xpress / Sun safety ad balancing visuals and messaging gets young people to listen
Research behind the skin cancer prevention campaign "If You Could See UV" has found that evoking fear of ultraviolet (UV) radiation exposure—through a visually striking metaphor—helped motivate young adults to protect their ...
Phys.org / What to know about the Artemis 2 mission's moon flyby
For the first time in more than half a century, astronauts will fly around the moon on Monday, marking the high point of the Artemis 2's lunar mission.
Medical Xpress / New therapeutic target identified for neuroendocrine tumors in the gastrointestinal tract
Neuroendocrine cells are unique in their ability to act both as nerve cells and hormone-making cells. They're scattered throughout the body, including the stomach, intestines, pancreas and lungs. Tumors that arise from these ...
Medical Xpress / US sexual health report card: High pleasure, low testing, stark gender disparities
A new sexual health survey reveals a mix of progress and persistent gaps. Overall, many Americans report positive experiences—interest in having sex, sexual pleasure, and good communication with partners—yet women and gender-diverse ...
Medical Xpress / Toxic dust from California's Salton Sea is harming children's lung growth—study tracks the impact in 700 kids
Southern California's Salton Sea was once a resort playground, with sunny beaches, celebrities and people waterskiing on the vast inland lake in the 1950s and '60s.
Phys.org / Gaia analysis finds Messier 35 is larger and older than earlier estimates
Astronomers from Egypt and Turkey have conducted a comprehensive analysis of kinematic, structural, and astrophysical parameters of a nearby open cluster known as NGC 2168. Results of the new study, published March 23 on ...
Tech Xplore / Opening the door to more efficient orbitronic devices
Electrons have three intrinsic properties: spin, charge and orbital angular momentum. Researchers have long studied how to use spin to more efficiently create an electrical current. But the field of orbitronics—which is based ...
Medical Xpress / Getting a scan? Time to results has doubled since 2014
A look at millions of medical imaging orders finds Americans are waiting twice as long now for their results as they did in 2014, with the biggest surge in wait times occurring recently.
Phys.org / New catalyst enables targeted antibiotic redesign to beat resistant bacteria
Antibiotics, our infantry against bacteria, are losing their ability to fight against bacterial infections due to the rise of superbugs—microbes that have developed resistance to medications that are designed to kill them. ...
