Tear fluid is emerging as an attractive source of diagnostic information because it can be collected easily and noninvasively. Changes in tear composition often reflect underlying physiological ...

Flashes of gravitationally lensed starlight could act as cosmic lighthouses revealing the presence of binary supermassive ...

Astronomers propose a new method to detect hidden supermassive black hole pairs using warped starlight, offering early clues before gravitational wave signals arrive.

Space rarely gives up its secrets easily. For instance, what looks like a single ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

A recent SpaceNews opinion article argued that it is time to “take astronomy off Earth.” The suggestion is straightforward: If satellite constellations and commercial space activity threaten ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

Gator Bio, a pioneer in biolayer interferometry (BLI) technologies, today announced the commercial launch of its Gator HIS XT probes, the first biolayer interferometry probes to incorporate ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

Indian companies landed orders worth up to Rs 15,000 crore across key sectors—explore the latest deals and their impact now!

They developed a unique sound-sensing design that uses a vibration-sensitive membrane and an internal glass micro-beam suspended inside a single-mode optical fiber. Together, these components form a ...

What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.
