Welcome to Science News Daily, your source for the latest breakthroughs and discoveries from the world of science. I'm your host, and today we're diving into some fascinating stories that span from medical mysteries to cosmic revelations.

Let's start with a concerning development in the pharmaceutical world. Investigators have uncovered new evidence of significant misreporting related to ticagrelor, a multibillion-dollar heart medication. The BMJ has identified problems with key platelet studies that supported the drug's FDA approval over a decade ago. This discovery raises important questions about the approval process and long-term use of this widely prescribed cardiac medication. It's a reminder of why rigorous oversight and transparency in medical research are absolutely crucial.

Speaking of medical breakthroughs, researchers at UC Riverside may have found a promising new approach to treating multiple sclerosis. Their study focuses on what they call "recharging brain cells" - specifically targeting inflammation in the cerebellum, the brain region that controls movement and balance. Since about 80 percent of people with MS experience cerebellar inflammation, leading to tremors and coordination problems, this research could potentially help millions of the 2.3 million people worldwide living with this condition.

Now, here's something many of us can relate to - that dreaded feeling when we think about exercising. But scientists have revealed how we can actually train our brains to like physical activity. The research explores the science of mental strength and resilience, showing how enduring mild physical discomfort helps our brains build new reference points for tolerance. It's fascinating to think that our relationship with exercise might be more malleable than we previously believed.

On a completely different note, researchers have been investigating what makes certain smells particularly offensive to us. We all know that microwaving fish is a social faux pas, but scientists are now understanding the brain mechanisms behind why some scents trigger such powerful negative emotional responses. This research involves specialized brain cells and could lead to improvements in sensory health treatments.

In environmental science, we have some exciting developments in carbon capture technology. Scientists at ETH Zurich are developing a revolutionary living material that removes carbon dioxide directly from the air, much like a tree does. This innovative approach uses photosynthetic bacteria to trap CO2 in both organic and mineral forms, combining conventional materials with microorganisms like bacteria, algae, and fungi. It's a fascinating example of biomimicry in action.

But not all environmental news is positive. A new satellite-based study has revealed alarming information about New Orleans - parts of the city are sinking at rates of nearly two inches per year. This includes some of the very flood walls built to protect it, potentially compromising the effectiveness of the city's 15-billion-dollar storm defense system. It's a stark reminder of the ongoing challenges coastal cities face.

On a more hopeful environmental front, scientists have discovered soil bacteria that can actually devour toxic "forever chemicals" - those persistent pollutants that pose serious risks to both human and environmental health. These eternal pollutants, including various per-fluorinated compounds, have been notoriously difficult to break down, so this bacterial solution could be a game-changer.

In the realm of quantum technology, researchers at EPFL have created a revolutionary biosensor that doesn't need an external light source - it actually generates its own glow using quantum tunneling. By guiding electrons through a nanostructure of gold and aluminum oxide, this tiny sensor can detect molecules at incredibly small concentrations, down to a trillionth of a gram.

The tech world is buzzing about a potential silicon replacement. Scientists in Tokyo have developed a crystal-powered transistor using gallium-doped indium oxide that could supercharge AI applications. This new transistor design achieves remarkable electron mobility and stability, potentially revolutionizing microelectronics.

In an impressive display of green chemistry, researchers at Flinders University have found a way to extract pure gold from electronic waste using nothing more than saltwater, UV light, and a recyclable polymer. This environmentally friendly method ditches toxic chemicals like cyanide and mercury, literally turning trash into treasure.

We also have some surprising medical discoveries. Researchers studying atherosclerosis have found that cells in diseased blood vessels actually grow in a way that resembles tumor development. This unexpected finding could lead to entirely new treatment strategies for cardiovascular disease.

From the cosmos, astronomers have discovered a record-breaking radio halo that's 10 billion light-years away and dates back to when the universe was much younger. This discovery suggests that galaxy clusters in the early universe were already filled with high-energy particles, possibly from ancient black hole activity or cosmic particle collisions.

Here's a remarkable story of scientific redemption - a toxic mold once blamed for killing scientists exploring ancient tombs, including those associated with the so-called "pharaoh's curse," is now being engineered into powerful cancer-fighting molecules. Scientists at Penn have transformed compounds from Aspergillus flavus into ring-shaped peptides called asperigimycins that rival FDA-approved leukemia drugs.

Finally, researchers have discovered that our financial behavior, recorded in routine banking data, might serve as an early warning system for dementia. Changes in spending patterns and login habits can potentially signal cognitive decline up to ten years before any formal medical intervention occurs. It's a fascinating example of how everyday data might hold keys to early disease detection.

That wraps up today's Science News Daily. From quantum sensors to ancient molds turned cancer fighters, from sinking cities to bacteria that eat forever chemicals, science continues to surprise and inspire us. Keep looking up, keep asking questions, and we'll see you tomorrow with more discoveries from the amazing world of science.
