The plastic tips attached to the ends of shoelaces keep them from fraying. Telomeres are repetitive DNA (deoxyribonucleic acid) sequences that serve a similar function at the end of chromosomes, protecting its accompanying genetic material against genome instability, preventing cancers and regulating the aging process.

Each time a cell divides in our body, the telomeres shorten, thus functioning like a molecular “clock” of the cell as the shortening increases progressively with aging. An accurate measure of the quantity and length of these telomeres, or “clocks,” can provide vital information if a cell is aging normally, or abnormally, as in the case of cancer.

To come up with an innovative way to diagnose telomere abnormalities, a research team led by Assistant Professor Cheow Lih Feng from the NUS Institute for Health Innovation & Technology (iHealthtech) has developed a novel method to measure the absolute telomere length of individual telomeres in less than three hours. This unique telomere profiling method can process up to 48 samples from low amounts (1 ng) of DNA.

When six-time Powerboat World Champion Erik Stark climbs aboard a boat, it’s often to rocket toward a gold medal at around 150 mph (240 km/h). But today we’re all getting a chance to go along for a ride as he tests out a very different type of boat: Candela’s electric hydrofoil boat.

The opportunity comes via Stark’s new Team Subtech video where he toured the Candela factory in Stockholm, Sweden.

At the other extreme is the massive Dyson Sphere, theorized by physicist Freeman Dyson – a metallic globe large enough to hold a star at its centre and contain a human population at a sufficient distance from the star to comfortably support their survival. This is a highly theoretical idea and is more of a thought experiment than a workable design, at least with any foreseeable technology.

Concerns have been raised about what kinds of governments might take hold in space settlements, and what possible risks they might face from ever more powerful economic and military establishments back on Earth.

This gorgeous, stainless steel and bronze toy car is simply named Toy Car, which seems an appropriately stripped-down name for such a minimalist vehicle. Without a body, or even a cover over the engine, you can see exactly how the car works.

It’s essentially a fancy version of the pull-back-and-go cars found in cereal boxes and kids’ fast-food “meals” everywhere. Pull the car backwards while pushing down and the motion of the turning wheels is stored as energy in a coiled spring inside the big central toothed wheel. Let go and it unwinds, propelling the machine forward. When the spring has fully sprung, a clutch disengages and lets the car roll free.

Testing teams have successfully completed a critical milestone focused on demonstrating that NASAs James Webb Space Telescope will respond to commands once in space.

Known as a “Ground Segment Test,” this is the first time commands to power on and test Webb’s scientific instruments have been sent to the fully-assembled observatory from its Mission Operations Center at the Space Telescope Science Institute (STScI) in Baltimore, Maryland.

Since reliably communicating with Webb when in space is a mission-critical priority for NASA, tests like these are part of a comprehensive regimen designed to validate and ensure all components of the observatory will function in space with the complex communications networks involved in both sending commands, and downlinking scientific data. This test successfully demonstrated the complete end-to-end flow from planning the science Webb will perform to posting the scientific data to the community archive.

Tesla CEO Elon Musk has updated the timeline on which he sees batteries enabling electric aircraft coming to maket. He now sees it happening in “3 to 4 years.” Several years ago, Musk, the CEO of both Tesla and SpaceX, said that he had a design for electric vertical take-off and landing (VTOL) a…

Tesla CEO Elon Musk has been talking about the electric plane for a long time. He even said he has an electric vertical take-off and landing (VTOL) aircraft project, though he never went into details about plans to launch it into production.

Summary: An estimated 13.6% of deaths in the U.S could be attributed to dementia. The number is 2.7 times higher than the official reported dementia-related deaths. The underestimation varies greatly by race, with 7.1 times more older Black adults, and 4.1 times more Hispanic adults, dying from dementia that public records indicate.

Dementia may be an underlying cause of nearly three times more deaths in the U.S. than official records show, according to a new Boston University School of Public Health (BUSPH) study.

Summary: Discovery reveals neurons can lose their individuality in some conditions. The findings contradict the conventional belief that neurons always stay separated and never fuse.

A discovery that could rewrite the textbooks on neurons could also help us understand the basis of some neurological diseases.
