Macs will now inform Apple if liquid is detected in USB-C

While Apple offers limited warranty and doesn't cover damages caused by liquids, the company has though, devised a method to detect if device has been exposed to liquids, especially on the Macs USB-C port.

MacOS Sonoma 14.1 includes a new system daemon called "liquiddetectiond" which can identify if device has been exposed to liquids, running background detection analysis from each USB-C port.

Described as a “Liquid Detection and Corrosion Mitigation Daemon," iPhones and iPads have similar daemons which immediately informs users of liquid is detected in the connector. The code on the Mac, however, suggests that the daemon is only being used for analytics and is not associated with end-user features. It seems that this detection will be more likely used for technicians to determine if a Mac is eligible for free warranty repair.

Strategically placed in the device, these dectectors change colour when in contact with liquid, indicating the presence of liquid damage.

Alzheimer's may be caused by immune cells thinking brain cells are bacteria, expert says

The pursuit of a cure for Alzheimer's disease is becoming an increasingly competitive and contentious quest with recent years witnessing several important controversies. In July 2022, Science magazine reported that a key 2006 research paper, published in the prestigious journal Nature, which identified a subtype of brain protein called beta-amyloid as the cause of Alzheimer's, may have been based on fabricated data. One year earlier, in June 2021, the U.S. Food and Drug Administration had approved aducanumab, an antibody-targeting beta-amyloid, as a treatment for Alzheimer's, even though the data supporting its use were incomplete and contradictory. Some physicians believe aducanumab never should have been approved, while others maintain it should be given a chance. With millions of people needing an effective treatment, why are researchers still fumbling in this quest for a cure for what is arguably one of the most important diseases confronting humankind?

Your heart changes in size and shape with exercise – this can lead to heart problems for some athletes and gym rats

Exercise has long been recognized by clinicians, scientists and public health officials as an important way to maintain health throughout a person’s lifespan. It improves overall fitness, helps build strong muscles and bones, reduces the risk of chronic disease, improves mood and slows physical decline. Exercise can also significantly reduce the risk of developing conditions that negatively affect heart heath, such as high blood pressure, high cholesterol and obesity. But large amounts of exercise throughout life may also harm the heart, leading to the development of a condition called athletic heart. As the Sports cardiology director at the University of Colorado Anschutz Medical Campus, I’m often asked how much and what kind of exercise is necessary to get the benefits of exercise . Many people also wonder about the risks of exercise , and what happens if you exercise too much. The American Heart Association generally recommends 150 minutes of moderate-intensity exercis...
