Nature's red alert: 5 species that went extinct while we watched
The last few years were quite ominous for conservationists and wildlife lovers everywhere. Climate change, deforestation, and pollution have long been known as causes of extinction, but 2019 to 2024 saw a rapid increase in species going extinct.

The official announcement of extinction is not to be taken lightly and takes years, and very often decades, of intensive surveys and ecological information.
The following are five species that were officially confirmed as extinct between 2019 and 2024, using official sources such as the International Union for Conservation of Nature (IUCN) and national environmental departments.
Chinese Paddlefish (Psephurus gladius)
Credit: Wikipedia
Confirmed extinct: July 2022 (IUCN)
Last spotted: Early 2000s
Habitat: Yangtze River, China
One of the world's largest freshwater fish, the Chinese paddlefish, was officially declared extinct in 2022.
Reaching more than 7 meters in length, it was a top predator in the Yangtze River for millions of years. But dam building (particularly the Gezhouba Dam), overfishing, and habitat fragmentation put an end to its life. No one has been seen despite exhaustive search campaigns since 2003. The paddlefish was considered "functionally extinct" in 2019 before it was delisted from the IUCN Red List in 2022.
Mountain Mist Frog (Litoria nyakalensis)
Announced extinct: October 2020 (IUCN)
Last recorded: 1990
Distribution: Queensland, Australia
This rare frog had previously inhabited the rainforests of uplands in northeastern Australia.
It started declining in the latter half of the 20th century due to the transmission of chytrid fungus, a highly lethal pathogen on amphibians globally. By 1990, the species was completely extinct. It was officially declared extinct by the IUCN in 2020, after intense surveys had failed to provide any indication of its continuation.
Poʻouli (Melamprosops phaeosoma)
Credit: Wikipedia
Declared extinct: 2021 (U.S. Fish & Wildlife), 2024 (IUCN)
Last seen: 2004
Habitat: Maui, Hawaii
The Poʻouli, a honeycreeper native to Hawaii, was a bird that inhabited forests with exceptional feeding habits and a distinctive look.

It was first discovered in 1973, and its population quickly dwindled because of habitat loss, introduced predators such as rats and cats, and disease transmitted by mosquitoes. The last recorded specimen died in captivity in 2004. In 2021, the U.S. formally recommended its delisting as an endangered species because it had gone extinct.
IUCN also verified the status of extinction in 2024.
Campo Grande Tree Frog (Boana cymbalum)
Declared extinct: 2023 (IUCN)
Last spotted: Only once in 1968
Habitat: São Paulo, Brazil
Recorded from a single locality and observation in 1968, this Brazilian tree frog has not been seen since targeted searching.
Urbanization at speed, pollution, and deforestation of forested habitats led to its suspected extinction. In 2023, the IUCN officially declared the Campo Grande tree frog to be extinct, another case of how biodiversity can be lost before a species can even be scientifically examined.
Cheongpung Blind-Beetle (Coreoblemus parvicollis)
Declared extinct: 2023 (IUCN)
Last observed: Unknown
Habitat: Cheongpung, South Korea
A subsurface cave beetle restricted to a limited region of South Korea, the beetle went unnoticed when it silently became extinct after environmental alterations due to dam construction and flooding in the area.
Its extinction was authenticated by the IUCN in 2023. Lacking its unknown nature, very little information is available, which is usually true with underground or micro-endemic organisms.
Is this nature warning us against a bigger threat?
These five species are among the hundreds that could be lost this decade. Every extinction carries a greater message: the Earth's biodiversity is in trouble. Over 47,000 species are threatened with extinction, and many will likely go silently into oblivion without ever being globally noticed, states the IUCN Red List. Whereas extinction is irreversible, activist conservation, restoration of habitats, and international cooperation can reverse this trend.
The question remains: Will we do so before the next one is erased from the list.

What is China really doing in space? Mysterious satellite maneuver stuns experts
China's activities in space have recently taken a quiet but significant turn, which might be a sign of a major evolution in how we think about satellite operations. In today's world, technology, sustainability, and national security are intertwined with one another. Such missions seem to explore the possibilities far above Earth. Recent movements by China in geostationary orbit are being closely watched by the space community, which has posted the observations on its official X handle. On January 6, 2025, a Long March 3B rocket launched from Xichang carried Shijian‑25 into geostationary transfer orbit. Built by Shanghai Academy of Spaceflight Technology (SAST), it's officially tasked with 'satellite fuel replenishment and life extension service technology verification,' reported Shijian-21 was launched in October 2021 on a Long March 3B rocket. Its mission was to dock with an old, no longer working satellite called Beidou-2 G2 and move it to a safe, out-of-the-way orbit above the regular geostationary satellites. This 'graveyard orbit' helps keep space clear and prevents collisions with active satellites. Both these Chinese satellites made a close approach in June Ground‑based tracking by S2A Systems detected Shijian‑21 and ‑25 converging in GEO during mid‑June. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 4BHK+Family Lounge+Utility room at 4.49Cr (All Incl)* ATS Triumph, Gurgaon Book Now Undo On June 14, they were 'virtually unresolvable from the other,' indicating a close rendezvous, which is likely expected to be a docking test, as reported by Observations also noted earlier manoeuvres on June 13 and 14, and an expected rendezvous around June 11 based on their orbital trajectories. How can this test be useful? Refuelling and servicing satellites in GEO could drastically extend their service life, reduce space debris, and lower launch demands. Shijian‑25 was intended to rendezvous with Shijian‑21 because they are in a phased orbit, which means sharing orbital elements but staggered in longitude, which can result in lowering the fuel needed for proximity operations. Although this mission is described as a civilian technology test, the close movements of the satellites have raised some concerns. According to COMSPOC OPS on social media, two US satellites, called USA 270 and USA 271, are nearby, probably keeping an eye on the Chinese satellites. COMSPOC explained, 'USA 270 and 271 now flank SJ-21 and SJ-25 from the east and west—potentially enabling favorable sun angles depending on the timing of closest approach. ' According to COMSPOC, the ongoing activity between China's Shijian-21 and Shijian-25 satellites is unfolding in a particularly busy and sensitive area of geostationary orbit (GEO). COMSPOC also stated clearly, 'While these U.S. assets aren't directly involved, their proximity adds complexity to the local SSA picture — and raises strategic awareness concerns.' In other words, even if there's no direct interaction, just being close in such a critical orbital region makes the dynamics more complicated and potentially riskier.

US lawmakers probe University of Michigan over Chinese nationals accused in agroterrorism fungus smuggling case
US Congress is investigating the University of Michigan. The probe focuses on research ties to Chinese nationals. These individuals are accused of smuggling a harmful fungus. The fungus poses a threat to crops. Lawmakers are concerned about security lapses. They also worry about Chinese government influence. The investigation involves multiple congressional committees. They are examining federal research funding. Tired of too many ads? Remove Ads Tired of too many ads? Remove Ads A range of congressional committees has initiated an extensive investigation into professors and research facilities at the University of Michigan associated with two Chinese nationals accused of bringing a "potential agroterrorism " fungus into the United States , as reported by The National Review (TNR).Since 2010, these professors have obtained around USD 9.6 million in federal research support and have previously held positions at institutions in both China and the US Congressional investigators also discovered that Zunyong Liu, one of the two Chinese researchers charged earlier this month with smuggling, is noted as an affiliate in a Chinese-government-sponsored research talent program, according to allegedly received funding from a province in China for research on the fungus this year, while his co-defendant and girlfriend, Yunqing Jian, was taken into custody this month. Liu is believed to be absconding in China. Letters have been sent to the University of Michigan, the National Institutes of Health, and the National Science Foundation."Taxpayer dollars should never support research associated with the Chinese Communist Party , especially when it involves dangerous biological substances. These arrests highlight serious deficiencies in oversight. We urge the NIH, NSF, and the University of Michigan to promptly take measures to safeguard our laboratories and national security," a spokesperson for the House Select Committee on the Chinese Communist Party stated, as cited by the TNR addition to the China committee led by Representative John Moolenaar, the House Committee on Education and the Workforce and the House Committee on Science, Space and Technology are also conducting the inquiry. The chairpersons of these committees are Representatives Tim Walberg and Brian Stone. The 25 Republican signatories of the letters also included Representatives Elise Stefanik, Neal Dunn, and Virginia and Jian faced charges in Michigan earlier this month for smuggling a harmful, crop-destroying fungus called Fusarium graminearum. This incident raised significant concerns regarding security lapses in university court documentation, the Justice Department referenced academic studies indicating that the fungus leads to crop diseases affecting wheat, barley, maize, and corn, resulting in economic damages amounting to billions of dollars each year, while the FBI cited academic sources describing it as a "potential agroterrorism weapon."These arrests occurred after the Trump administration declared it would take strong action to revoke visas for Chinese students linked to the CCP who were studying in critical technology fields. This hardline stance was later softened by US President Donald Trump amid trade discussions with China. Liu and Jian have both recently been associated with the University of Michigan's Molecular Plant-Microbe Interaction Laboratory, as noted in the is also identified as a researcher backed by China's "Hundred Talents Program" on the website of Zhejiang University, according to the letters. "The Hundred Talents Program is a talent recruitment initiative sponsored by the Chinese government that, according to the Federal Bureau of Investigation, 'aims to attract a younger talent pool' of individuals who exhibit 'internationally-recognised expertise,'" the letter states, as mentioned by the TNR surrounding the Chinese government's talent programs primarily relate to allegations of intellectual property and research theft from American universities by Beijing . The letter further indicates that Liu has benefited from other Chinese government funding initiatives, including a grant from Zhejiang province to advance his work on Fusarium this after the initial accusations against Liu and Jian were made, federal agents indicted a third Chinese national, Chengxuan Han, for reportedly smuggling roundworms into the US for use by recipients at the University of Michigan in what seems to be an unrelated serves as the party secretary of a CCP branch for students at Huazhong University of Science and Technology, which, like Zhejiang University, is overseen by SASTIND, according to a letter from House members, as reported by general, the lawmakers cautioned: "These incidents underscore potential instances of non-compliance and other weaknesses within the US research security framework despite years of federal efforts."
