Remember to watch part 1: https://youtu.be/tANAl15CCLE

Welcome to the year 2,324, where humanity has transcended its Earthly origins to build civilizations across the solar system. Mars, Titan, and even the clouds of Venus are now home to more than 2.5 billion people, thanks to anti-aging technologies and AI-driven advancements. But how did we get here? And what does life look like in this brave new world? In this continuation of my speculative future series, I explore the political structures, societal shifts, and technological innovations that define our interplanetary existence. Get ready for a journey through a transformed solar system!

Scientists discover molecules that store much of the carbon in space

A team led by researchers at MIT has discovered that a distant interstellar cloud contains an abundance of pyrene, a type of large, carbon-containing molecule known as a polycyclic aromatic hydrocarbon (PAH).

The discovery of pyrene in this far-off cloud, which is similar to the collection of dust and gas that eventually became our own solar system, suggests that pyrene may have been the source of much of the carbon in our solar system. That hypothesis is also supported by a recent finding that samples returned from the near-Earth asteroid Ryugu contain large quantities of pyrene.

A “wearable” device for individual neurons can measure electrical activity in the brain

Posted by in categories: biotech/medical, neuroscience, wearables

MIT researchers have developed a battery-free, subcellular-sized device made of polymer designed to measure and modulate a neuron’s electrical and metabolic activity. When the device is activated by light, it can gently wrap around the neuron cell’s axons and dendrites without damaging the cells.

Scientists want to inject thousands of these tiny wireless devices into a patient’s central nervous system and then actuate them noninvasively using light. The light would penetrate the tissue and allow precise control of the devices, and thereby restore function in cases of neuronal degradation like multiple sclerosis (MS).

The MIT researchers developed these thin-film devices from a azobenzene, a soft polymer that readily reacts to light. Thin sheets of azobenzene roll into a cylinder when exposed to light, which enables them to wrap around cells. Researchers can control the direction and diameter of the rolling by changing the intensity and polarization of the light, producing a microtube with a diameter smaller than one micrometer.

Gene therapy Improves Eye Health and Reduces the Need for Anti-VEGF Injections in Age-Related Macular Degeneration

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

RegenxBio, a publicly-traded biotech firm, released data this week from a Phase 2 clinical trial designed to test its leading genetic therapy product in patients with bilateral wet age-related macular degeneration (AMD). AMD is characterized by abnormal growth of blood vessels in the retina, and is a leading cause of loss of vision in elderly populations globally.

ABBV-RGX-314, developed in collaboration with AbbVie, offers the potential of a one-time treatment for wet AMD and other retinal conditions, including diabetic retinopathy. This is in contrast to existing treatments which rely on repeated intraocular injections of drugs that inhibit a protein known as Vascular Endothelial Growth Factor (VEGF), a protein responsible for the formation of new retinal blood vessels.

The ABBV-RGX-314 therapy is based on a an AAV8 viral vector as a delivery system. The AAV8 platform has been genetically engineered to encode an antibody that can inhibit VEGF for the long-term.

Scientists believe popular drug could end the mysterious outbreak of colon cancer in young people

Posted by in categories: biotech/medical, food

Most recently, 90s heartthrob and Dawson’s Creek star James Van Der Beek announced he’d been diagnosed with colorectal cancer at the age of just 47.

The rise is mysterious, but experts suspect ultra-processed foods, pollution and the over use of antibiotics could be driving microscopic cancer-causing changes in the body’s cells.

Now, a team of scientists across five nations, including at King’s College London, have been given £20 million by charities including Cancer Research UK to fund fresh studies that will begin early next year, The Times reported.

Cornell’s Breakthrough Could Mean the End of Exploding Batteries

Posted by in categories: energy, innovation

Researchers at Cornell have engineered a groundbreaking porous crystal using a unique fusion of macrocycle and molecular cage structures, enhancing lithium-ion transport in solid-state batteries.

This new crystal design features one-dimensional nanochannels that significantly increase ion conductivity, a development that promises safer batteries and has potential applications in water purification and bioelectronics.

By fusing two contorted molecular structures, Cornell researchers have developed a porous crystal capable of absorbing lithium-ion electrolytes and smoothly transporting them through one-dimensional nanochannels. This innovative design has the potential to enhance the safety of solid-state lithium-ion batteries.
