Continuous non-invasive glucose sensing on the horizon with the development of a new optical sensor

For decades, people with diabetes have relied on finger pricks to withdraw blood or adhesive microneedles to measure and manage their glucose levels. In addition to being painful, these methods can cause itching, inflammation ...

Hormonally up-regulated neu-associated kinase (HUNK) unveils a new function in cellular transport regulation

Endocytosis is a crucial cellular process that facilitates cells to take up cargos by enclosing them in membrane-bound vesicles, which are transported to different parts of the cell via the endosomal system and deliver cargos ...

SpaceX's 3rd Starship launch makes it to space without exploding, but is lost on reentry

SpaceX's powerful Starship and Super Heavy rocket completed a more successful third orbital test flight from Texas on Thursday morning with no explosive endings on the way up that marred the first two test flights in 2023.

Total solar eclipses provide an opportunity to engage with science, culture and history

On April 8, 2024, there will be a total solar eclipse in Canada. This is an opportunity to experience, learn from and participate in the excitement and wonder. And rather than hiding inside, researchers have been communicating ...

Explaining a supernova's 'string of pearls'

Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around supernova 1987A, research from ...

Researchers generate super-fast electrons with table-top laser systems

In massive particle accelerators, sub-atomic particles (like electrons) are sped up to super-high speeds comparable to the speed of light towards a target surface. The collision of accelerated sub-atomic particles gives rise ...

Study shows inverting fusion plasmas improves performance

To become commercially viable, fusion power plants must create and sustain the plasma conditions necessary for fusion reactions. However, at high temperatures and densities, plasmas often develop gradients in those temperatures ...

During the 2024 solar eclipse, Texans will aid a national research effort to study the sun

On a sunny February day at Dallas' Frontiers of Flight Museum, a cluster of students lifted telescope equipment out of a bulky briefcase. A sticker on the case read: "stand back—we're going to science!"

Giving particle detectors a boost: New device acts like a superconductivity switch

In particle colliders that reveal the hidden secrets of the tiniest constituents of our universe, minute particles leave behind extremely faint electrical traces when they are generated in enormous collisions. Some detectors ...

Preventing magnet meltdowns before they can start

The particle accelerators that enable high-energy physics and serve many fields of science, such as materials, medical, and fusion research, are driven by superconducting magnets that are, to put it simply, quite finicky.
