Breakthroughs, discoveries, and DIY tips sent six days a week. If you're someone who mosquitoes just, we feel your pain.

At least 60 people have been killed in a drone strike at a displacement shelter in el-Fasher, a besieged Sudanese city on the brink of collapse. The resistance committee for el-Fasher, made up of local citizens and activists, said the paramilitary Rapid Support Forces (RSF) hit Dar al-Arqam camp, located within a university, with two drone strikes and eight artillery shells. Children, women and the elderly were killed in cold blood, and many were completely burned, a statement from the group said. Eyewitnesses described scenes of panic as rescuers pulled bodies from the rubble. Hospitals already struggling under months of siege have been overwhelmed, with doctors treating the wounded on floors and in corridors.

How healthy am I? My immunome knows the score. Groundbreaking new tests reveal patterns in our immune systems that can signal underlying disease and tell us how well we might recover from our next cold. I got my results in a text message. It's not often you get a text about the robustness of your immune system, but that's what popped up on my phone last spring. Sent by John Tsang, an immunologist at Yale, the text came after his lab had put my blood through a mind-boggling array of newfangled tests. The result--think of it as a full-body, high-resolution CT scan of my immune system--would reveal more about the state of my health than any test I had ever taken. And it could potentially tell me far more than I wanted to know. "David," the text read, "you are the red dot." Tsang was referring to an image he had attached to the text that showed a graph with a scattering of black dots representing other people whose immune systems had been evaluated--and a lone red one.

Breakthroughs, discoveries, and DIY tips sent every weekday. Mosquitoes may have just met their match: A prescription drug already used to treat a rare genetic disease in humans can make a person's blood poisonous to insecticide-resistant, malaria-carrying mosquitoes. New research published on July 31, 2025, in Parasites & Vectors found that the same drug, nitisinone, can even kill mosquitoes that simply land on a surface sprayed with the chemical. The findings could open up new avenues to stop the spread of diseases like malaria and dengue, especially as more mosquito populations evolve to become resistant to traditional prevention methods. Whether people will willingly offer their bodies as mosquito blood bait, though, remains less clear.

After Hall of Fame athlete Deion Sanders' announcement that he battled bladder cancer, doctors are sharing warning signs to monitor. Sanders, who is currently head football coach at the University of Colorado Boulder, spoke about his medical struggles during a Monday press conference held at Folsom Field in Boulder. The former NFL and MLB star, 57, appeared alongside his care team and representatives from University of Colorado Health (UC Health) and University of Colorado Anschutz Medical Campus (CU Anschutz). Sanders was diagnosed with "very high-risk, non-muscle invasive bladder cancer," but is now cancer-free, according to a statement from his oncologist. It was very high-grade and invading through the bladder wall," said Dr. Janet Kukreja, urological oncology director at CU Anshutz. "I am pleased to report that the results from the surgery are that he is cured from the cancer." Head coach Deion Sanders of the University of Colorado speaks about his journey beating bladder cancer during a press conference in the Touchdown Club at Folsom Field in Boulder, Colorado, on July 28, 2025. The oncologist noted that Sanders' type of cancer has a very high rate of recurrence and progression. Treating the disease within the bladder would require a long series of treatments over a three-year period, and there would still be a 50% chance of the cancer coming back. The cancer could also have spread to the muscle, the doctor said, which happens in about half of cases. "Only about 10% of people live five years, even with our current medical treatment, if it metastasizes," she said. Together with his care team, Sanders made the decision to have a bladder removal, in which surgeons performed a "full robot-assisted laparoscopic bladder removal" and created a new bladder. "It is a new way of life.
