In new research published in BMC Medicine, the authors recruited a large cohort of participants in order to assess how plant-based foods affect aging trajectories [1].

Previous research has shown that consumption of plant-based foods is associated with healthy aging [2,3]. It can also help to decrease the risk of mortality [4], prevent the development of chronic diseases [5,6], and improve neurological health, such as by lowering the risk of dementia [7] and cognitive impairment [8].

This new study aimed to determine the influence of a plant-based diet on the aging trajectory of the middle-aged Asian population. Researchers recruited over 10,000 people 50 years and older in Taiwan. Participants provided health data four times during the eight years after enrollment, underwent physical examinations, and filled out relevant questionnaires.

AAV development for cell and gene therapy in 2023 is being impacted by manufacturing and regulation challenges, however advancing technologies offer opportunity, according to leaders in the field.

As proven by recent regulatory approvals sweeping the cell and gene therapy industry, particularly within Europe and the US, these pioneering treatments have demonstrated great capacity in helping to resolve hard-to-treat diseases.

Recently, we spoke to Shai Efrati MD, Chair of Aviv Clinics’ Medical Advisory Board and Founder and Director of the world-leading Sagol Center for Hyperbaric Medicine and Research, about the longevity and healthspan benefits of hyperbaric oxygen therapy (HBOT). The Aviv Medical Program is designed for individuals experiencing cognitive and physical decline because of a variety of conditions, including stroke, post-COVID and age-related cognitive decline, Aviv also has an increasing number of clients who wish to improve their cognitive and physical performance and increase their healthspan.

One of Aviv’s patients is Patti Finnegan, a senior living in The Villages in Florida, and we sat down with her to find out what HBOT entails for the patient.

Longevity. Technology: At Longevity. Technology, we often cover therapies and treatments that have been developed or launched, discussing the science behind them and the possible results for the patient. What is less common, however, is to hear from the patients themselves – how did they find the experience and has it made a difference? What starts in a test tube or a white board ends up in a person, so it is important to retain a focus on the end user; after all, while patient population data is important, improving outcomes for actual people is the key goal behind longevity science – real people living longer, healthier lives.

Are democratic societies ready for a future in which AI algorithmically assigns limited supplies of respirators or hospital beds during pandemics? Or one in which AI fuels an arms race between disinformation creation and detection? Or sways court decisions with amicus briefs written to mimic the rhetorical and argumentative styles of Supreme Court justices?

Decades of research show that most democratic societies struggle to hold nuanced debates about new technologies. These discussions need to be informed not only by the best available science but also the numerous ethical, regulatory and social considerations of their use. Difficult dilemmas posed by artificial intelligence are already… More.

Even AI experts are uneasy about how unprepared societies are for moving forward with the technology in a responsible fashion. We study the public and political aspects of emerging science. In 2022, our research group at the University of Wisconsin-Madison interviewed almost 2,200 researchers who had published on the topic of AI. Nine in 10 (90.3%) predicted that there will be unintended consequences of AI applications, and three in four (75.9%) did not think that society is prepared for the potential effects of AI applications.

Who gets a say on AI?

Industry leaders, policymakers and academics have been slow to adjust to the rapid onset of powerful AI technologies. In 2017, researchers and scholars met in Pacific Grove for another small expert-only meeting, this time to outline principles for future AI research. Senator Chuck Schumer plans to hold the first of a series of AI Insight Forums on Sept. 13, 2023, to help Beltway policymakers think through AI risks with tech leaders like Meta’s Mark Zuckerberg and X’s Elon Musk.

A former Google executive who helped pioneer the company’s foray into artificial intelligence fears the technology will be used to create “more lethal pandemics.”

Mustafa Suleyman, co-founder and former head of applied AI at Google’s DeepMind, said the use of artificial intelligence will enable humans to access information with potentially deadly consequences.

“The darkest scenario is that people will experiment with pathogens, engineered synthetic pathogens that might end up accidentally or intentionally being more transmissible,” Suleyman said The Diary of a CEO podcast on Monday.

Female kidneys are known to be more resilient to disease and injury, but males need not despair. A new USC Stem Cell-led study published in Developmental Cell describes not only how sex hormones drive differences in male and female mouse kidneys, but also how lowering testosterone can “feminize” this organ and improve its resilience.

“By exploring how differences emerge in male and female kidneys during development, we can better understand how to address sex-related health disparities for patients with diseases,” said Professor Andy McMahon, the study’s corresponding author, and the director of the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at the Keck School of Medicine of USC.

First authors Lingyun “Ivy” Xiong and Jing Liu from the McMahon Lab and their collaborators identified more than 1,000 genes with different levels of activity in male and female mouse kidneys, in a study supported by the National Institutes of Health. The differences were most evident in the section of the kidney’s filtering unit known as the proximal tubule, responsible for reabsorbing most of the nutrients such as glucose and amino acids back into the blood stream.

An essential protein that acts as a gatekeeper for calcium entering cells promotes the growth of oral cancer and generates pain, according to a new study published in Science Signaling led by researchers at New York University College of Dentistry.

Targeting this protein—the ORAI1 —could provide a new approach to treating oral cancer, which causes persistent that worsens as it progresses.

“Our results show that the ORAI1 channel fuels the growth of oral cancer tumors and produces an abundance of molecules that, once secreted, interact with neurons resulting in an increased sensitivity to pain,” said Ga-Yeon Son, a postdoctoral fellow in the Department of Molecular Pathobiology at NYU College of Dentistry and the study’s first author.

The current crop of AI robots has made giant leaps when it comes to tiny activities.

There are robots performing colonoscopies, conducting microsurgeries on and nerve cells, designing , constructing delicate timepieces and conducting fine touch-up operations on fading, aging classical paintings by the masters.

Robots are able to handle delicate objects thanks to what researchers call passive compliance. That is the ability to change their state in response to .
