First Light

A game developer working on an open-source lightmapping tool tested it with a sunny outdoor scene and found it failed completely. The problem was that the sun disk is encoded as positive infinity, which broke the lighting math, so they added a clamping feature to handle extreme values. The fix is being shared with the game development and indie developer community.

Researchers claim to have identified the location and figures in Louis Daguerre's early 19th-century photograph, believed to show the first human subjects ever captured on camera. The finding sheds new light on the origins of photography and the people unwittingly immortalized in the historic daguerreotype, resolving a question that has puzzled historians for nearly two centuries.

NASA's Voyager 1, now 25.85 billion km (16.06 billion miles) from Earth, is days away from becoming the first human-made object to sit a full light-day away, with a signal from the probe taking nearly 24 hours to arrive. Voyager 2 trails at 21.65 billion km. Space enthusiasts are tracking the milestone using NASA's solar system tools.

Researchers report in Nature that the transcription factors OVOL1 and OVOL2 regulate trophectoderm differentiation as an early mammalian embryo develops from a morula into a blastocyst. The finding clarifies how the first cell lineage decisions are controlled, a key step in understanding fertility, implantation and developmental biology.

Winter weather advisories are in effect in the Pacific Northwest, with forecasters warning of up to a foot of snow in the Cascade mountains. Meanwhile, Utah's high country has seen its first snowfall of the season, with a light powder dusting mountain peaks and ski resorts. The early-season snow signals the start of winter conditions across the western United States.

The International Council on Clean Transportation has released a global electric vehicle market monitor covering light-duty vehicles in key markets for the first half of 2026. The tracker compiles registration and sales data to compare how quickly major economies are shifting away from combustion vehicles. It offers researchers and policymakers an updated snapshot of EV adoption across the world's most important car markets.

The Immigration Project, an advocacy organisation, addressed recent immigration enforcement activity and confirmed that more than 10 people were detained. The group is providing information about those affected as communities seek details on who was taken and where they are being held. The confirmation sheds light on the scale of the operation, which had otherwise not been publicly detailed.

Bangladesh opener Shadman Islam was left stranded on 99 not out when bad light halted play in the first Test against the West Indies. He anchored the innings as Bangladesh reached 213 for 3, falling one run short of a Test century on the day's play.

Astronomers have, for the first time, detected a radio signal coming from a planet orbiting the young star Beta Pictoris, about 63 light years from Earth. Italian science outlets report the finding as a milestone, since picking up radio emissions from an exoplanet could open a new way to study magnetic fields and planetary systems beyond our own.

A new retrospective highlights the NBA draft classes of the early 2000s, led by LeBron James, taken first overall by Cleveland in 2003, and Kevin Durant, selected second by Seattle in 2007. Both became all-time greats and multi-time champions, prompting fans to debate which era's draft class was the strongest in league history.

A British Columbia driver says the Hyundai Kona electric vehicle they bought last October cost just $414 to charge at home over its first year. The figure came to light while reviewing an annual BC Hydro equalized payment adjustment, which rose by $25 a month. The owner charges the car almost exclusively at home.

Retreating glaciers in the Dolomites have exposed a cache of first world war munitions, a legacy of the fighting between Italian and Austro-Hungarian forces that took place in the high mountains between 1915 and 1918. The discovery highlights how climate change is exposing long-buried artefacts and hazards from the conflict, and experts are warning of the dangers posed by the ageing ammunition.

NASA's Voyager 1, now about 25.85 billion km (16.06 billion miles) from Earth, is roughly 22 days away from reaching a distance of one light-day — the time light takes a full day to travel. Its twin Voyager 2 sits about 21.64 billion km (13.45 billion miles) away. Space enthusiasts are marking the milestone as the probe continues its 47-year journey into interstellar space.

Scientists report that the oceanic plate off Vancouver Island is fracturing, offering what researchers describe as the first clear view of a subduction zone in its final stages. The observation gives geologists a rare chance to study how tectonic plates break down over millions of years, shedding light on seismic activity in the Pacific Northwest.

A recently surfaced rare letter sheds light on how George Washington's family coped with a stepdaughter's epilepsy. The document offers a personal glimpse into the private medical struggles of the first family of American history, detailing the care and concern surrounding the young woman's condition at Mount Vernon.

Researchers have unearthed fossil evidence of what is described as the first amphibian known to live fully in the sea, according to findings reported by UC Davis scientists and circulated via EurekAlert!. The discovery sheds new light on how vertebrate ancestors transitioned from land back into marine environments. Details of the species and fossil site have not yet been widely elaborated in available coverage.
