The space-inspired wastewater treatment uses the nutrients and loses the odor. Breakthroughs, discoveries, and DIY tips sent every weekday. When most people need to go number one, they find the nearest bathroom and don't give half a thought to what happens to their pee once it disappears down the toilet or urinal . It turns out that the nitrogen in human urine can be used in fertilizer. However, humanity's use of nitrogen is everything but efficient, according to a pair of siblings who founded the Swiss start-up company, VunaNexus.

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.

A new space suit designed by scientists at Weill Cornell Medicine and Cornell University, inspired by Frank Herbert's Dune, could make spacewalks longer and less disgusting by recycling expelled urine in a special filtration backpack. The traditional NASA spacesuit design has been in circulation since the 1970s and only has an absorbent polymer to catch astronauts' urine. This outdated waste system has also led to hygiene and medical issues, like urinary tract infections (UTIs) and gastrointestinal problems, for astronauts. The new'stillsuits' have a "vacuum-based external catheter leading to a combined forward-reverse osmosis unit" astronauts carry on their back. The suits were designed for future NASA space missions, including the Artemis II and Artemis III missions, both headed to the moon.

The idea of drinking your own urine might sound like a survival technique promoted by Bear Grylls. But it could soon become a reality for astronauts, thanks to a new Dune-inspired spacesuit. The spacesuit is the brainchild of researchers from Cornell University and features a futuristic device that can recycle urine into drinking water. While the suit is still a prototype, it could be a godsend for astronauts, who are currently forced to relieve themselves inside their spacesuits during long spacewalks. 'The design includes a vacuum-based external catheter leading to a combined forward-reverse osmosis unit, providing a continuous supply of potable water with multiple safety mechanisms to ensure astronaut wellbeing,' said Sofia Etlin, first author of the study.

For dog lovers, the idea of friendly canines as living, breathing, tail-wagging cancer detectors is a hopeful one. Not only do dogs conjure smiles, but their known olfactory abilities would offer a strange contrast to the sterile medical exam rooms many find dreadful: brushed steel countertops, white lab coats, buttercup walls, and the penetrating smell of disinfectants. But if dogs have already shown the ability to detect cancer on human breath or urine, researchers have now found one better: Ants could be a more cost-effective means of harnessing the same super-sniffing abilities of their distant cousin canines to help detect cancer and other illnesses in humans. We may eventually be able to use both dogs and ants to train artificial intelligence-powered devices to do the same thing. "Insects have a life that is much shorter than that of mammals. They have to learn fast," says Patrizia d'Ettorre, an expert in ant behavior at University Paris 13 in France.

Billionaire VC Tim Draper (via Draper Associates) has led a $6 million Series A in wellness tracking startup, Vivoo. Also participating in the funding round is ONCE Ventures, Revo Capital, 500 Startups (which backed its pre-seed), Global Ventures, and (the female-led consumer tech startup focused) Halogen Ventures. The personalized nutrition and lifestyle startup sells subscription-based at-home urine test kits that work in conjunction with an app. Its machine learning technology remotely analyzes a user's peed-on test strip to serve up custom'wellness' insights, then and there, offering recommendations across a range of areas such as nutrition and biological function. The startup's founding team is led by CEO and co-founder Miray Tayfun, a serial founder and bioengineer by background who graduated from Stanford's postgraduate programs.

Depending on the robot's work, sustainability could look different from machine to machine. In general, making a more sustainable robot starts with ethically sourced recycled or sustainable materials, functioning as energy efficiently as possible. Then the robot has to be repairable if broken and recyclable when it's time to retire. While some sensors or computer chips might not currently be recyclable or reusable, those pieces wouldn't make up a large percentage of the machine. Some definitions of sustainability include the robot's function.

Patients are determined to have prostate cancer primarily based on *PSA, a cancer factor in blood. However, as diagnostic accuracy is as low as 30%, a considerable number of patients undergo additional invasive biopsy and thus suffer from resultant side effects, such as bleeding and pains. The Korea Institute of Science and Technology (KIST) announced that the collaborative research team led by Dr. Kwan Hyi Lee from the Biomaterials Research Center and Professor In Gab Jeong from Asan Medical Center developed a technique for diagnosing prostate cancer from urine within only twenty minutes with almost 100% accuracy.

Numerous studies have shown that trained dogs can detect many kinds of disease -- including lung, breast, ovarian, bladder, and prostate cancers, and possibly Covid-19 -- simply through smell. In some cases, involving prostate cancer for example, the dogs had a 99 percent success rate in detecting the disease by sniffing patients' urine samples. But it takes time to train such dogs, and their availability and time is limited. Scientists have been hunting for ways of automating the amazing olfactory capabilities of the canine nose and brain, in a compact device. Now, a team of researchers at MIT and other institutions has come up with a system that can detect the chemical and microbial content of an air sample with even greater sensitivity than a dog's nose.
