Google Photos on Android gets a sleeker bottom navigation bar

Google Photos for Android is rolling out a redesigned, more compact bottom bar that keeps Photos, Collections, and Create in a single pill with a separate round Search button; the layout is persistent across views and reduces screen real estate, following an iOS update earlier in 2026, with the rollout now broad on Android (noted on Pixel devices with version 7.82).

Oman-Iran talks hint at tolls for Strait of Hormuz

Oman and Iran used a Muscat meeting to stress sovereignty over the Strait of Hormuz and to discuss services and costs for transit, signaling a potential tolls regime on ships passing through the waterway. The two nations announced plans to form a joint working group to decide the future administration of navigation. While President Trump has opposed tolls, analysts say tolls or fees are likely after the current ceasefire ends, and such fees could shape shipping, insurance requirements, and energy markets, with Oman continuing to play a key mediator role.

Honeybees Follow Personal Flight Maps with Centimeter-Precision Navigation

University of Freiburg researchers used a drone-based Fast Lock-On tracking system to attach markers to honey bees and map high-resolution 3D flight paths in a natural landscape near Kaiserstuhl, Germany. They found that individual bees follow highly consistent, personally preferred routes and repeat them with centimeter-level precision, using landmarks such as trees to stay on course; monotone areas like cornfields reduce cues and increase variability. The results imply that bees are far more accurate navigating to familiar destinations than suggested by the waggle dance, which conveys directional information that is less precise than the bees’ actual navigation to known sites.

Liver-Based Quantum Compass May Guide Pigeons Home

German researchers provide evidence that iron-rich macrophages in pigeons' livers may possess superparamagnetism and act as a liver-based quantum compass to help navigation, particularly when the Sun is obscured; experiments using clodronate to wipe these immune cells disrupted homing on overcast days, while normal navigation returned under sunny conditions, implying a liver-to-brain signaling pathway.

Pigeons rely on a liver-based compass to navigate cloudy skies

Scientists trained 34 pigeons to navigate a 12‑mile route and found iron‑rich immune cells in the liver may act as an internal magnetic compass, helping them sense Earth's magnetic field when visual cues are blocked by clouds. Pigeons depleted of these cells got lost under overcast skies, while birds with normal iron stores completed the route; after the cells naturally repopulated, navigation improved again. The cells display superparamagnetism and may relay directional information to the brain via nerves from the liver. While some scientists praise the possible new mechanism of magnetic perception, others call for more direct evidence before drawing firm conclusions. The research team plans to further investigate how immune cells communicate with the nervous system and to track pigeons globally to learn more about their navigation skills.

Apollo 13's Wristwatch Burn: Navigating Home by the Terminator Line

Facing a life-or-death power budget after Apollo 13's oxygen-tank explosion, the crew shut down nonessential systems, used the Aquarius lunar module as a lifeboat, and manually performed a 14-second trajectory burn by aligning Earth's terminator in the LM window and timing it with Swigert’s Omega Speedmaster—an improvised navigation method that ensured a splashdown and became a lasting NASA contingency lesson.

Relativity at GPS scale: why satellites are clocked slow on the ground

GPS satellites carry atomic clocks that are deliberately set to run slow on the ground so that relativistic effects in orbit bring them to the correct rate; special relativity would slow moving clocks by about 7 microseconds per day, while general relativity would speed them up by about 45 microseconds per day, for a net gain of roughly 38 microseconds per day that would cause ~10 km of positional error daily if uncorrected. The main correction is a ground-based frequency offset (about 10.22999999543 MHz instead of 10.23 MHz) so the clock is right in orbit, with smaller orbital variations corrected by the receiver.

The Price of GPS: How Our Sense of Place Is Eroded by Tech

The piece argues that widespread GPS use over the past decade and a half has shifted most people from a hippocampus-driven cognitive map to a caudate-driven, autopilot navigation style. Those who still rely on memory maintain a relational, map-like understanding of their environment and a continuous sense of being oriented in space, while others gain efficiency at the cost of declining spatial memory. Reversing this would require deliberately navigating without GPS in selected contexts to exercise the cognitive map and reclaim a felt sense of location.

Starlink drops GPS-style PNT feature, but researchers aren’t done with space-based navigation

Starlink has shut down its GPS-like positioning, navigation, and timing (PNT) capability as of May 20, 2026, ending a peripheral feature that could offer location data even where GPS is jammed. SpaceX did not give a reason, fueling speculation about liability or a paid-service path ahead of an IPO. Independent researchers have already shown how Starlink signals can be exploited to determine location—with tens of seconds to meters-level accuracy—and have extended similar techniques to include OneWeb and other LEO constellations, suggesting robust GPS alternatives may emerge even after Starlink’s own PNT access is closed.

GPS III: A Major Leap for Global Positioning

The GPS III rollout is progressing with SpaceX's launch of the 10th GPS III satellite, forming the first complete block of third‑generation satellites. Over the next decade, up to 22 GPS III satellites will replace aging units, bringing higher transmit power, a new 1176 MHz Safety of Life signal, and military spot beams to improve resistance to jamming. New interoperable signals L1C and L2C will enhance compatibility with Galileo, BeiDou, IRNSS, and QZSS, while M‑code will bolster security for military users. Looking ahead, GPS IIIF satellites will add optical reflectors, laser data links, and the Digital Rubidium Atomic Frequency Standard. For most users, improvements will be subtle, mainly faster signal locks and more accurate positioning, with upgrades largely invisible in everyday use.

Apple Maps unlocks personalized 'Suggested Places' in iOS 26.5

iOS 26.5 adds a two-item, personalized Suggested Places row in Apple Maps' search field, based on trending spots and your past searches; this builds on iOS 26's Visited Places, Preferred routes, and Apple Intelligence, which together make Maps smarter and more convenient, though ads are expected this summer and the author would like more than two suggestions (perhaps a horizontally scrolling list) once available.

Field Observations Hint Tarantulas Use Learning and Memory in Hunting

Field observations of nine hunting cases in arboreal and fossorial tarantulas across the Americas suggest these spiders can learn and remember, adapting their hunting by using spatial information. Arboreal species moved up to two meters to better-lit hunting spots, fossorial tarantulas climbed to the canopy—even in the dry season—and several spiders, including a blind cave-dwelling species, returned quickly and directly to their burrows after disturbance. While the findings point to learning and memory, it remains unclear whether external landmarks or internal cues guide navigation, and researchers call for further field work and controlled experiments to confirm the cognitive interpretation.

Storm-Struck Antarctic Mission Uncovers Uncharted Island in the Weddell Sea

During a storm-evading leg of its mission, Germany’s RV Polarstern sighted what looked like a dirty iceberg that proved to be a rocky island rising from ice in the northwestern Weddell Sea, measuring about 130 by 50 meters. The feature, hidden under ice for decades in a region labeled an ‘unexplored danger zone,’ was confirmed using multibeam sonar and a drone, and its true position differs from existing charts by roughly one nautical mile. It currently has no official name, but will be submitted for international approval and added to nautical charts, underscoring the value of direct bathymetric surveys in polar regions.
