The traces we leave on the Web and on our digital devices can give advertisers and others surprising, and sometimes disturbing, insights into our psychology.
We’re used to the security risks posed by someone hacking into our computers, tablets, and smartphones, but what about pacemakers and other implanted medical devices? To help prevent possible murder-by-hacker, engineers at Purdue University have come up with a watch-like device that turns the human body into its own network as a way to keep personal technology private.
A collaboration between online technology company Enjin and the SENS Research Foundation has just been announced with the bold plan to mobilize a community of 20 million video gamers to help fight aging.
Enjin is a cryptocurrency and online video game company with a plan to change how donors and charities interact in a bid to make fundraising for globally important causes more effective.
This collaboration with SENS Research Foundation is the first program on the road to this goal. The project is essentially gamifying the fundraising experience to make it more fun and engaging for donors. To achieve this, donors get rewards for their donations in the form of blockchain-based collectibles known as “non-fungible tokens” (NFTs).
My colleague Conor Sen recently made a bold prediction: Government will be the driver of the U.S. economy in coming decades. The era of Silicon Valley will end, supplanted by the imperatives of fighting climate change and competing with China.
This would be a momentous change. The biggest tech companies — Amazon.com, Apple Inc., Facebook Inc., Google (Alphabet Inc.) and (a bit surprisingly) Microsoft Corp. — have increasingly dominated both the headlines and the U.S. stock market:
On Monday, OpenAI’s leaders said that a paltry $1 billion wouldn’t be enough to compete with the well-resourced AI labs at companies such as Google and Facebook after all. They announced the new investment vehicle, a company called OpenAI LP, as a way to raise extra money for the computing power and people needed to steer the destiny of AI. Musk left the board of OpenAI last February and is not formally involved in OpenAI LP.
OpenAI, the independent research lab cofounded by Elon Musk, created a for-profit arm to attract more funding to hire researchers and run computers.
We are learning more about fungal infection and neurological diseases. Recently we learned of gingival diseases and Alzheimer’s. My wonder is how plants such as Moringa in one’s diet, that have antifungal properties, can help.
Fungal infections are emerging as a major medical challenge, and a team led by researchers at Baylor College of Medicine has developed a mouse model to study the short-term consequences of fungal infection in the brain.
The researchers report in the journal Nature Communications the unexpected finding that the common yeast Candida albicans, a type of fungus, can cross the blood-brain barrier and trigger an inflammatory response that results in the formation of granuloma-type structures and temporary mild memory impairments in mice. Interestingly, the granulomas share features with plaques found in Alzheimer’s disease, supporting future studies on the long-term neurological consequences of sustained C. albicans infection.
“An increasing number of clinical observations by us and other groups indicates that fungi are becoming a more common cause of upper airway allergic diseases such as asthma, as well as other conditions such as sepsis, a potentially life-threatening disease caused by the body’s response to an infection,” said corresponding author Dr. David B. Corry, professor of medicine-immunology, allergy and rheumatology and Fulbright Endowed Chair in Pathology at Baylor College of Medicine.
The latest Facebook hack should have shown everyone nothing is safe. Researchers have now shown how easy it is to steal data from people doing research.
Engineers at the University of California say they have demonstrated how easy it would be to snoop on biotech companies making synthetic DNAll you need is an audio recording, they say. Place a smartphone near a DNA synthesizer, record the sound, run the recording across algorithms trained to discern the clicks and buzzes that particular machine makes, and you’ll know exactly what combination of DNA building blocks it is generating.
Researchers devise method for snooping on DNA synthesis using acoustic recordings. But is it a real threat?
There’s a good chance that in the future, microscopic robots could be swimming and crawling their way through our bodies to deliver drugs or fight infections. While some of these have been capable of manipulating individual cells, researchers at the University of Toronto have developed a new way to get nano-scale probes inside cells, and precisely control them once they’re in there.
Thirty-three older adults between the ages of 58 and 95 applied the cream all over their bodies twice a day for 30 days. After a month, the researchers measured blood levels of three cytokines—interleukin-1 beta, interleukin-6, and tumor necrosis factor (TNF) alpha—that have all been implicated in age-related inflammatory diseases. Using the cream reduced the amount of all three cytokines compared to both the participants’ levels before using the cream and the levels of similarly aged adults who did not use the cream. In fact, using the cream lowered participants’ cytokine levels to be nearly equivalent with people in their 30s, suggesting that rejuvenating the skin can reverse “inflamm-aging.” The cream also improved skin hydration, lowered pH, and repaired the permeability barrier.
Skin is the body’s largest organ, and scientists at UC San Francisco and the San Francisco Veterans Administration (VA) Health Care System think it may be to blame for body-wide inflammation linked to numerous chronic diseases of aging. The good news is that properly caring for the skin with a moisturizing cream may lower inflammation levels and potentially prevent age-related diseases, according to a new clinical pilot study.
As humans get older, we experience a low-level of inflammation—dubbed “inflamm-aging”—driven by an increase in molecules in the blood called cytokines. This age-related inflammation has been linked to serious chronic diseases, including Alzheimer’s disease, cardiovascular disease, and diabetes. Scientists initially thought that the inflammation stemmed from the immune system or the liver, but a group of dermatologists at UCSF have a different theory.
“The inflammation must come from an organ big enough that very minor inflammation can affect the whole body. Skin is a good candidate for this because of its size,” said study senior author Mao-Qiang Man, MD, a research scientist in the UCSF Department of Dermatology, who is based at the San Francisco VA Health Care System and is also a visiting professor at Southern Medical University in Guangzhou, China. “Once we get old, we have dermatological symptoms like itchiness, dryness, and changes in acidity. It could be that the skin has very minor inflammation, and because it’s such a large organ it elevates circulating cytokine levels.”
