Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), the University of California at Berkeley, and Aarhus University have taken an intriguing step forward by fabricating “PortaChrome,” a portable light system and design tool that can change the color and textures…

The portable light system and design tool “PortaChrome” uses UV and RGB LEDs to activate photochromic dye, reprogramming everyday objects like shirts. The MIT CSAIL researchers’ software can help users turn items into multicolor displays of fashion designs and health data.

NASA crew and ground-based scientists are sending blood cells to the International Space Station on November 4 to learn why astronauts have a higher risk of blood clots.

A study led by Umeå University, Sweden, presents new insights into how stem cells develop and transition into specialized cells. The discovery can provide increased understanding of how cells divide and grow uncontrollably so that cancer develops.

“The discovery opens a new track for future research into developing new and more effective treatments for certain cancers,” says Francesca Aguilo, associate professor at the Department of Molecular Biology at Umeå University and leader of the study in collaboration with various institutions including the University of Pavia, University of Texas Health Science Center at Houston, Universidad de Extremadura, and others.

All cells in the body arise from a single fertilized egg. From this single origin, various specialized cells with widely differing tasks evolve through a process called cellular differentiation. Although all cells share the same origin and share the same genetic information, specialized cells use the information in different ways to perform different functions. This process is regulated by genetic and epigenetic mechanisms.

On this episode, neuroscientist and author Robert Sapolsky joins Nate to discuss the structure of the human brain and its implication on behavior and our ability to change. Dr. Sapolsky also unpacks how the innate quality of a biological organism shaped by evolution and the surrounding environment — meaning all animals, including humans — leads him to believe that there is no such thing as free will, at least how we think about it today. How do our past and present hormone levels, hunger, stress, and more affect the way we make decisions? What implications does this have in a future headed towards lower energy and resource availability? How can our species manage the mismatch of our evolutionary biology with our modern day challenges — and navigate through a ‘determined’ future?

Researchers connecting pieces of the massive Alzheimer’s puzzle are closer to slotting the next one in place, with yet another link between our guts and brain.

Animal studies have demonstrated Alzheimer’s can be passed on to young mice through a transfer of gut microbes, confirming a link between the digestive system and the health of the brain.

A 2023 study adds further support to the theory that inflammation could be the mechanism through which this occurs.

At some point in your life, you must’ve experienced a lightbulb moment when an amazing idea just popped into your head out of nowhere. But what is your brain doing during these brief periods of creativity?

Researchers from the University of Utah Health and Baylor College of Medicine looked into the origin of creative thinking in the brain. They found that different parts of the brain work together to produce creative ideas, not just one particular area.

“Unlike motor function or vision, they’re not dependent on one specific location in the brain,” Ben Shofty, the senior author of the study and an assistant professor of neurosurgery at the Spencer Fox Eccles School of Medicine, said. “There’s not a creativity cortex.”

Bioengineered bacteria to eat plastic in seawater:3 Which in large quantities can eat all the plastic in the ocean:3 Yay face_with_colon_three

Poly(ethylene terephthalate) (PET) is a highly recyclable plastic that has been extensively used and manufactured. Like other plastics, PET resists natural degradation, thus accumulating in the environment. Several recycling strategies have been applied to PET, but these tend to result in downcycled products that eventually end up in landfills. This accumulation of landfilled PET waste contributes to the formation of microplastics, which pose a serious threat to marine life and ecosystems, and potentially to human health. To address this issue, our project leveraged synthetic biology to develop a whole-cell biocatalyst capable of depolymerizing PET in seawater environments by using the fast-growing, nonpathogenic, moderate halophile Vibrio natriegens. By leveraging a two-enzyme system—comprising a chimera of IsPETase and IsMHETase from Ideonella sakaiensis —displayed on V. natriegens, we constructed whole-cell catalysts that depolymerize PET and convert it into its monomers in salt-containing media and at a temperature of 30°C.

Scientists have developed a new material capable of capturing the harmful chemical benzene from the polluted air, offering a potential solution for tackling a major health and environmental risk.
