Scientists Can Now “See” Aging Through Your Eyes

The small blood vessels in the eye could reveal important clues about a person’s risk of heart disease and the rate at which they are biologically aging, according to scientists from McMaster University and the Population Health Research Institute (PHRI) – a joint institute of Hamilton Health Sciences and McMaster.

Published in the journal Science Advances, the research suggests that retinal scans may eventually become a simple, non-invasive way to assess the body’s vascular health and aging process. This approach could pave the way for earlier detection of health issues and more effective preventive care.

“By connecting retinal scans, genetics, and blood biomarkers, we have uncovered molecular pathways that help explain how aging affects the vascular system,” says Marie Pigeyre, senior author of the study and associate professor with McMaster’s Department of Medicine.

Hyundai joins US’ 11 gigawatt nuclear reactor project in Texas

Hyundai Engineering & Construction (Hyundai E&C) has taken a major step in expanding its global nuclear energy footprint.

On October 26, the company announced that it signed a basic design contract with Fermi America, a U.S.-based energy development firm, for the construction of four large nuclear reactors in Texas. The project will form part of what is expected to be the world’s largest integrated energy and artificial intelligence (AI) campus.

Taiwan-based tech company to locate first US manufacturing facility in Georgetown

Pegatron officials will start construction on the Georgetown facility before the end of the year, the news release states. The company will invest a minimum of $35 million in capital in the city, and will hire at least 100 employees within the first three years of opening.

“The jobs and investment this corporation is bringing to Georgetown mark a milestone in our community’s economic growth,” Georgetown Mayor Josh Schroeder said in the news release. “Their decision to put down roots here will have a lasting, positive impact on our community and the broader region for generations.”

“I Mapped the Invisible”: American High School Senior Baffles Scientists by Uncovering 1.5 Million Celestial Objects Hidden in Deep Space

A teenage student digging through old NASA data has uncovered a hidden trove of over a million cosmic objects using AI—reshaping what scientists thought they knew about the night sky.

Leaf arrangement steers vascular pattern evolution in ferns, research finds

Research by Assistant Professor Jacob S. Suissa at the University of Tennessee, Knoxville, is revealing complexity in how ferns have evolved. Instead of the vascular structure inside fern stems changing as a direct adaptation to the environment, he discovered that shifts in vascular bundle arrangement in the stem are developmentally covaried with leaf placement on the stem.

“As leaf number increases, we see a direct 1:1 increase in vascular bundle number, and as the placement of leaves along the stem changes, we also see a shift in the of vascular bundles in the stem,” said Suissa, a member of UT’s Department of Ecology and Evolutionary Biology.

For 150 years, researchers have focused on how vascular bundles adapt to the environment. Suissa’s new research, published in Current Biology, suggests leaves are steering the evolution of vascular patterns inside the stem.

An old fish fossil tells a new story about lamniform shark evolution

An international, multi-university research team, including scientists from Columbus State University, has unearthed a crucial new piece of the puzzle in the evolution of sharks.

A recent study published in Communications Biology, “Early gigantic lamniform marks the onset of mega-body size in modern shark evolution,” has identified a new, extinct lamniform shark—a group that includes modern-day great white and mako sharks. It marks the earliest known example of a gigantic shark, suggesting that the trend of mega-body size in modern shark evolution began much earlier than previously thought.

The team, led by Dr. Mohamad Bazzi of Stanford University, included Dr. Mike Newbrey of Columbus State’s Department of Biology and 2020 alumna Tatianna Blake. They derived their conclusions after studying specimens from the Darwin Formation that outcrops at Darwin, Australia. These specimens, collected by other researchers in the 1980s, had been stored in a museum collection and remained unstudied until recently, when the team examined them in detail.

Starship could cut the travel time to Uranus in half

The ice giants remain some of the most interesting places to explore in the solar system. Uranus in particular has drawn a lot of interest lately, especially after the 2022 Decadal Survey from the National Academies named it as the highest priority destination. But as of now, we still don’t have a fully fleshed out and planned mission ready to go for the multiple launch windows in the 2030s.

That might actually be an advantage, though, as a new system coming online might change the overall mission design fundamentally. Starship recently continued its recent string of successful tests, and a new paper presented at the IEEE Aerospace Conference by researchers at MIT looked at how this new, much more capable launch system, could impact the development of the Uranus Orbiter and Probe (UOP) that the Decadal Survey suggested.

Uranus is one of the least explored planets—the last probe to visit it was Voyager 2 during a flyby 40 years ago. Neither it, nor its ice giant cousin Neptune, have ever had an orbiter visit it, nor any consistent mission presence in their system, marking them out as the only two planets that haven’t been studied in detail up close so far.
