In the more than six million years since people and chimpanzees split from their common ancestor, human brains have rapidly amassed tissue that helps decision-making and self-control.
The large prefrontal cortex provides evolutionary and cognitive advantages over non-human primates — but there’s a cost.
Did you know letting crushed garlic sit for 10+ minutes before cooking it helps preserve more of its healthy polyphenols from heat? I learned a bunch of similar tidbits while researching this article on the best longevity foods!

A new material developed by Tohoku University records and stores stress history in structures through a luminescent effect, offering an innovative solution to monitor aging infrastructure without needing power or complex equipment.
Identifying deteriorating infrastructure can be as challenging as fixing it. However, researchers at Tohoku University have made this process easier with the development of an innovative new material.
The material responds to mechanical stimuli by recording stress history through a luminescent effect called an afterglow. This information is stored for a long time, and by applying the material to the surfaces of structures, researchers can observe changes in the afterglow to determine the amount of stress the material has experienced.
This new technology will give doctors a closer look. Introducing Pillbot: a tiny disposable robot that you swallow to let doctors see inside your body. In a live demo on the TED Talk stage, creators Alex Luekbe and Vivek Kumbhari show how this pill-sized device navigates the inside of your stomach with a camera, giving a direct view of the entire organ — without the discomfort of invasive procedures — paving the way for further exploration of the human body. “Inside each and every one of us holds mysteries and wonders that if unlocked, lead to better health, performance and longevity,” says Luebke.

What does the future hold? What will become of this planet and its inhabitants in the centuries to come?
We are living in a historical period that sometimes feels like the prelude to something truly remarkable or terribly dire about to unfold.
This captivating video seeks to decipher the signs and attempt to construct plausible scenarios from the nearly nothing we hold in our hands today.
As always, it will be scientific discoveries leading the dance of change, while philosophers, writers, politicians, and all the others will have the seemingly trivial task of containing, describing, and guiding.
Before embarking on our journey through time, let me state the obvious: No one knows the future!
Numerous micro and macro factors could alter this trajectory—world wars, pandemics, unimaginable social shifts, or climate disasters.
Nevertheless, we’re setting off. And we’re doing so by discussing the remaining decades of the century we’re experiencing right now.

The brain undergoes dynamic functional changes with age1,2,3.
Analyses of neuroimaging datasets from 5,306 participants across 15 countries found generally larger brain-age gaps in Latin American compared with non-Latin American populations, which were influenced by disparities in socioeconomic and health-related factors.

Proposed lunar biorepository could store genetic samples without electricity or liquid nitrogen. New research led by scientists at the Smithsonian proposes a plan to safeguard Earth’s imperiled biodiversity by cryogenically preserving biological material on the moon. The moon’s permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen, according to the researchers.
The paper, published today in BioScience and written in collaboration with researchers from the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI), Smithsonian’s National Museum of Natural History, Smithsonian’s National Air and Space Museum and others, outlines a roadmap to create a lunar biorepository, including ideas for governance, the types of biological material to be stored and a plan for experiments to understand and address challenges such as radiation and microgravity. The study also demonstrates the successful cryopreservation of skin samples from a fish, which are now stored at the National Museum of Natural History.
“Initially, a lunar biorepository would target the most at-risk species on Earth today, but our ultimate goal would be to cryopreserve most species on Earth,” said Mary Hagedorn, a research cryobiologist at NZCBI and lead author of the paper. “We hope that by sharing our vision, our group can find additional partners to expand the conversation, discuss threats and opportunities and conduct the necessary research and testing to make this biorepository a reality.”
M any prominent people in the tech industry have talked about the increasing convergence between humans and machines in coming decades. For example, Elon Musk has reportedly said he wants humans to merge with AI “to achieve a symbiosis with artificial intelligence”
His company Neuralink aims to facilitate this convergence so that humans won’t be “left behind” as technology advances in the future. While people with disabilities would be near-term recipients of these innovations, some believe technologies like this could be used to enhance abilities in everyone.
These aims are inspired by an idea called transhumanism, the belief that we should use science and technology to radically enhance human capabilities and seek to direct our own evolutionary path. Disease, aging and death are all realities transhumanists wish to end, alongside dramatically increasing our cognitive, emotional and physical capacities.
