Citizen science is public participation in research, enabling volunteers to collect or analyze data for ecology, astronomy, and biodiversity studies.
McGill researchers found urban areas near the equator hold 42% fewer bird species than natural ones nearby, versus 12% at 65 degrees latitude. The tropics' usual lead in species richness is therefore smaller in cities.
Reality
Amateur astronomer Pavel Rabtsevich searched TESS data for more than 126,000 stars with AI agents and flagged TIC 4206066 as a super-Earth candidate. Three other searches had also picked up the signal, and thruster firings may explain some of the dips, so the planet is unconfirmed.
Reality
Max Planck researchers report that New Zealand banded dotterels reached Australia about four days later each year from 2014 to 2025, judging by eBird sightings. The authors say the trend could eventually end the Tasman Sea crossing, a forecast they have yet to test on individual birds.
Reality
University of Michigan researchers prompted Claude and ChatGPT to extract species interactions from eBird and iNaturalist comments, in a PNAS paper. The proof-of-concept found nonnative plants creeping into West Coast ecosystems that might otherwise go unnoticed.
Reality
Carlos Magdalena, Maarten Christenhusz and colleagues have named Victoria colombiana, one of three new giant waterlily species found in a few years. As far as the team knows it grows in one small area, where, Christenhusz says, a single pollution spill could wipe out the whole species.

University of Galway researchers comparing more than 450 snake species found venomous ones more likely to stand out against their habitats. That supports warning colouration across snakes, beyond textbook coral snakes, as a tendency with many drab venomous exceptions.
Reality
University of Miami researchers mapped Guam's Tumon Bay from the air and measured a 59% decline in massive coral cover after Typhoon Mawar. Maps that cover a whole bay at the scale of single colonies could guide where restoration money goes, if the classifier holds up on reef it was never trained on.
Reality
Cornell's WildFin team found standard vision models still misread fish behavior after tuning on nine hours of reef video that took about 2,000 hours to make. The team blames scarce wildlife footage in model training and is asking ecologists to release their field video, a remedy this study has not yet tested.
Reality
Southampton's Black Hole Hunters project wants volunteers to vet AI-screened telescope data for black holes beyond the roughly 70 whose locations are known. A volunteer's flag picks a target for telescope follow-up, and the team counts a discovery only once it detects gravitational self-lensing.
Reality
University of Sydney researchers have split Australia's Anchiale stick insects from two species into five, one laying eggs with a lidlike structure new to the group. The insects already had more than 1000 citizen-science records, and telling them apart took DNA analysis checked against museum specimens.
Reality
UConn researchers surveyed 233 plant enthusiasts and found they want expert training to identify emerging plant diseases and invasive species. Because respondents came through garden clubs and extension newsletters, the survey shows willing helpers exist but cannot size demand across the country.
Reality
Volunteers buried more than 2,000 pairs at about 1,000 Swiss sites and dug them up two months later, and land use predicted how much fabric vanished better than most of the soil chemistry measured. That makes cotton a usable, if coarse, field assay.

SLF's Flora Raetica project is resurveying Graubünden's plants on 1,104 one-hectare squares and comparing them with records made in the early 1930s. So far, the evidence that plants are moving uphill comes from one plot near Davos and a treeline estimate from co-leader Christian Rixen.
Reality
Sydney residents weight their bin lids and jam the hinges, and the birds still get in, so Lucy Aplin's team has taken a plexiglass box of unfamiliar latches to the Royal Botanic Garden to see what one cockatoo can work out alone.

An introduced population of Macquarie River turtles is moving through the Manning catchment in New South Wales. The researchers now tracking it with water samples are monitoring a species that two other states list as threatened.
Reality
The site holds about 17,000 tagged feeding observations covering some 5,700 species, contributed by roughly 2,000 observers in more than 100 countries. The team is still building tools to validate submissions.

Joel Lapointe noticed a circle near Lake Marsal while planning a 2024 camping trip in Quebec. A floatplane and a 50-metre wade later, Gordon Osinski's team found the shatter cones that decided its origin.

Cameron Peace's lab at Washington State matched leaves collected from old Maine farms to an apple ancestor his pedigree had inferred but never sampled. The tree that supplied them is still standing.
Reality
NC State researchers surveyed 1,854 Americans and found 60% or more interested in science or convinced it benefits society, 43% calling it credible and 39% feeling they belong in it. The fix they propose rests on about 260 self-selected participants.
Reality
Sarah Meier and Eric Strobl matched wildfire particulate data to volunteer bird counts on about 2,800 US survey routes from 2008 to 2022, and the diversity dip held on routes where nothing had burned within five kilometres.
