(Press-News.org)

The research group of fungal diversity and molecular evolution at Kunming Institute of Botany, Chinese Academy of Sciences conducted in-depth research on more than 1,600 samples of macrofungi collected from 2019 to 2024 by means of species identification combining morphology and molecular systematics. The results showed that there were 480 species of macrofungi in this area, covering 7 classes, 17 orders, 67 families, and 158 genera of Ascomycota and Basidiomycota, and 8 new species were described.

 

Fungal diversity patterns revealed taxonomic dominance at both family and genus levels. Among the 67 documented families, 15 were dominant (≥10 species each), collectively representing 22.39% of families and 64.58% of all species. Russulaceae was the most species-rich (79 species), followed by Agaricaceae (25), Cortinariaceae (25), Boletaceae (21), Inocybaceae (18), Hymenogastraceae (17), and Omphalotaceae (17). At the genus level, 23 of 158 genera (14.56%) contained ≥ 5 species each, accounting for 55.21% of total species diversity. Nine genera with more than 10 species were Lactarius (39), Russula (35), Cortinarius (25), Amanita (15), Entoloma (14), Inocybe (13), Mycena (12), Gymnopus (11), and Laccaria (11).

 

This study identified 480 fungal taxa. Within this assemblage, 115 edible (23.96%), 15 medicinal (3.13%), and 53 poisonous species (11.04%) were cataloged. Notable edible species included Tricholoma matsutake, Cantharellus cibarius, Cortinarius emodensis, Lactarius deliciosus, Lentinula edodes, Pleurotus abieticola, and Ramaria pallida, etc. Eight species served dual purposes as both edible and medicinal fungi: Cordyceps militaris, Hericium erinaceus, Hericium rajendrae, Megacollybia clitocyboidea, Naematelia aurantialba, Pholiota spumosa, Sarcodon imbricatus, and Schizophyllum commune. Common poisonous fungi comprised Amanita altipes, Amanita liquii, Clitocybe phyllophila, Coprinopsis atramentaria, Cortinarius subsanguineus, Galerina marginata, Hypholoma fasciculare, Leccinum scabrum, Paragyromitra infula, and Russula emetica.

 

This study not only provides important data support for global biodiversity protection, but also helps to formulate more scientific and reasonable protection strategies. In addition, some species found in the study show remarkable economic value and medicinal potential, which opens up new possibilities for the development and utilization of biological resources. This study not only enriches our understanding of the ecosystem in southeast Xizang, but also provides a solid foundation for biodiversity protection and resource utilization in the future.

New study on hope among U.S. youth reveals key to safer schools this fall

2025-08-06
Given the current youth mental health crisis in the United States, many adolescents report experiencing low levels of hope – a longstanding concern that is even more pressing as the new school year begins. Substantial research over decades has established that higher levels of hope are linked with greater academic achievement, as well as improved emotional and physical health. Now, a new study shows that hope does even more: it acts as a powerful protective force in the lives of children, helping to reduce both bullying and cyberbullying. The study by Florida Atlantic University, in collaboration with the University of Wisconsin–Eau Claire, surveyed a nationally representative ...

AI chatbots can run with medical misinformation, study finds, highlighting the need for stronger safeguards

2025-08-06
New York, NY [August 6, 2025] — A new study by researchers at the Icahn School of Medicine at Mount Sinai finds that widely used AI chatbots are highly vulnerable to repeating and elaborating on false medical information, revealing a critical need for stronger safeguards before these tools can be trusted in health care. The researchers also demonstrated that a simple built-in warning prompt can meaningfully reduce that risk, offering a practical path forward as the technology rapidly evolves. Their findings were detailed in the August 2 online issue of Communications Medicine ...

Nanoparticles for rheumatoid arthritis prevention, flare control

2025-08-06
As a chronic condition, rheumatoid arthritis (RA) can’t be cured, so treatment focuses on managing the disease and controlling its progression. Although current treatments help control RA symptoms in most people, they cannot prevent the onset of RA or painful flare-ups. Now, researchers publishing in ACS Central Science have developed nanoparticles that could slow disease progression and reduce flare severity, based on results from tests with human blood and mice models with RA-like disease. For a person diagnosed with RA, their immune system attacks tissue that makes up the joints, causing inflammation, swelling and pain. ...

Small-world networks can mitigate ESG controversies for multinationals, suggests new study

2025-08-06
Multinational enterprises (MNEs) can negate supplier-induced environmental, social and governance (ESG) controversies by setting up ‘small-world’ networks, according to new research co-authored by Bayes Business School. Globalising supply chains has become a dominant strategy for MNEs. Benefits include lower costs of labour and distribution, and greater scope for innovation. However, long-distance operations also carry associated risks. Contrasting ethical standards of suppliers in different areas of the world can lead to ...

Yonsei University researchers directly measure quantum metric tensor in real material

2025-08-06
Quantum distance refers to a measure of quantum mechanical similarity between two quantum states. A quantum distance of one means that the two quantum states are the same, whereas a quantum distance of zero implies that they are exactly the opposite. Physicists introduced this concept in the realm of theoretical science a long time ago, but its importance has been increasingly recognized in the field of physics only in recent times. In the last few years, many experimental physicists have tried to measure the quantum distance of electrons ...

TEER associated with improved survival in the elderly patients with AFMR

2025-08-06
The mitral valve controls blood flow between the heart’s left atrium and ventricle. When structural changes affect the atrium or valve, it may not close fully—causing blood to leak backwards, a condition known as atrial functional mitral regurgitation (AFMR). Common in frail or elderly patients, AFMR often leads to heart failure, and standard surgery is typically too risky due to other health issues.   Transcatheter edge-to-edge repair (TEER), a minimally invasive surgery, has emerged as a low-risk treatment option for various ...

Excessive screen time among youth may pose heart health risks

2025-08-06
Research Highlights: Increased time on electronic devices or watching TV among children and young adults was associated with higher cardiometabolic disease risk, such as high blood pressure, high cholesterol and insulin resistance, based on data from over 1,000 study participants in Denmark. The link between screen time and cardiometabolic risks was strongest among youth who slept fewer hours, suggesting that screen use may harm health by “stealing” time from sleep, researchers said. Researchers said the findings underscore the ...

Pure quantum state without the need for cooling

2025-08-06
  Three nano glass spheres cling to one another. They form a tower-like cluster, similar to when you pile three scoops of ice cream on top of one another – only much smaller. The diameter of the nano cluster is ten times smaller than that of a human hair. With the help of an optical device and laser beams, researchers at ETH Zurich have succeeded in keeping such objects almost completely motionless in levitation. This is significant when it comes to the future development of quantum sensors, which, together with quantum computers, constitute the most promising applications of quantum research. As part of their levitation ...

NHS Active 10 walking tracker users are more active after using the app

2025-08-06
Users of the NHS Active 10 app, designed to encourage people to become more active, immediately increased their amount of brisk and non-brisk walking upon using the app, according to researchers from the University of Cambridge. In a study published today in npj Digital Medicine, the researchers found that while activity levels then slowly declined over time, even after 30 months those users who were still using the app were more active than they had been beforehand. Lack of physical activity ...

Ultraviolet light reveals the aftermath of rare star collision

2025-08-06
University of Warwick astronomers have uncovered compelling evidence that a nearby white dwarf is in fact the remnant of two stars merging — a rare stellar discovery revealed through Hubble Space Telescope ultraviolet observations of carbon in the star’s hot atmosphere.  White dwarfs are the dense cores left behind when stars exhaust their fuel and collapse. They are Earth-sized stellar embers weighing typically half as much as the Sun, made up of carbon-oxygen cores with surface layers of helium and hydrogen. While white dwarfs ...
