Could conserving tigers in forests be an integral part of climate change solutions?

2025-05-07
(Press-News.org) Forests without top predators (such as tigers) risk being overgrazed by large herbivore prey, depleting vegetation carbon stocks and their capacity to remove carbon dioxide from the atmosphere, an essential ecosystem function for mitigating climate change. Therefore, just as forest protection and restoration can support top predator recovery “bottom-up,” large carnivore conservation likely promotes vegetation recovery “top-down” and represents an understudied component in nature-based solutions to climate change. Research published in Global Change Biology provides new insights into these relationships. 

Investigators found that tiger presence is associated with higher forest vegetation carbon stocks per unit area, as well as overall lower carbon dioxide emissions and higher carbon dioxide removal than tiger-absent forests. Also, forest vegetation or soil carbon stocks increased with tiger density in four forest habitat types studied. 

The findings reveal that tigers are both an indicator and a driver of forest ecosystem carbon stocks, depending on underlying ecological conditions, and could help safeguard against carbon emissions. 

“Our analysis indicates that tiger density can influence forest vegetation carbon stocks by controlling large herbivore prey, but there is important context-dependency and variable outcomes to consider,” said corresponding author Guangshun Jiang, PhD, of Northeast Forestry University, in China. “Rebuilding forest carbon stocks can support tiger population growth, while tiger presence also seems to have a guardian effect to protect forests from deforestation and associated carbon emissions.”

During aging, do people with Down syndrome face a higher risk of cardiovascular disease than other individuals?

2025-05-07
Because life expectancy for individuals with Down syndrome has increased dramatically, investigators assessed the risk of age-related cardiovascular diseases in this population. As reported in the Journal of Internal Medicine, the researchers found increased risks of various cardiovascular diseases compared with the general population.  In the study, 5,155 individuals with Down syndrome born in Sweden in 1946–2000 were compared with other Swedish individuals matched by sex, birthyear, and county of birth.  Down syndrome was associated with 4.41-times higher risk of ...

A pipette that can activate individual neurons

2025-05-07
Researchers at Linköping University have developed a new type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. Controlling the concentration of different ions can provide important insights into how individual braincells are affected, and how cells work together. The pipette could also be used for treatments. Their study has been published in the journal Small. “In the long term, this technology could be used to treat neurological diseases ...

Cannabis-related hospital visits rising, often tied to mental health conditions: Study

2025-05-07
By Amy Norton PISCATAWAY, NJ – More people are landing in the hospital with cannabis-related problems—and for many, a mental health condition is the primary issue, according to a new study published in the Journal of Studies on Alcohol and Drugs. The study, conducted in Arizona, found that between 2016 and 2021, cannabis-related hospital visits across the state rose by 20%. Among those visits, one quarter ended up with a primary diagnosis of a mental health condition, including bipolar disorder, depression, and psychotic disorder. That compared with only about 3% of visits unrelated to cannabis. Overall, people with a cannabis-related hospital visit ...

Humans prefer to put more effort into empathizing with groups than with individuals

2025-05-07
What makes us care about others? Scientists studying empathy have found that people are more likely to choose to empathize with groups rather than individuals, even though they find empathizing equally difficult and uncomfortable in both cases. The scientists suggest that the sight of groups of people could offer more context information which helps people decide whether to empathize, and therefore increases the chances that they choose to do so.   “People’s willingness to empathize is different depending on who the target is: a single individual ...

Development of high-performance proton exchange membrane for electrochemical LOHC hydrogen storage

2025-05-07
A Korean research team has developed a new proton exchange membrane (PEM) that significantly enhances the performance of electrochemical hydrogen storage systems. Dr. Soonyong So of the Korea Research Institute of Chemical Technology (KRICT) and Professor Sang-Young Lee of Yonsei University have developed a next-generation PEM for LOHC-based electrochemical hydrogen storage using a hydrocarbon-based polymer called SPAES (sulfonated poly(arylene ether sulfone)). This SPAES membrane reduces toluene ...

Feat of ‘dung-gineering’ turns cow manure into one of world’s most used materials

2025-05-07
The study, published in The Journal of Cleaner Production, describes the new ‘pressurised spinning’ innovation and its potential to create cellulose materials more cheaply and cleanly than some current manufacturing methods, using a waste product from the dairy farming industry, cow dung, as the raw material. The advance is the first time that manufacturing-grade cellulose has been derived from animal waste and is a prime example of circular economy, which aims to minimise waste and pollution by reusing and repurposing resources wherever possible. The ...

Women with serious mental health conditions likely ill-equipped for menopause transition

2025-05-07
CLEVELAND, Ohio (May 7, 2025)—Many women struggle to find resources to help manage their menopause symptoms. For women living with a serious mental illness, the need for additional support and education during the menopause transition is even greater. A new scoping review confirmed the paucity of research on this topic and suggested a need for more psychoeducation programs. Results of the study are published online today in Menopause, the journal of The Menopause Society. Serious mental illnesses are a group of mental health conditions often characterized by their chronicity and severity of symptoms that lead to significant functional impairment. ...

A research team led by Professor Yong-Young Noh and Dr. Youjin Reo from the Department of Chemical Engineering at POSTECH (Pohang University of Science and Technology) has developed a groundbreaking technology poised to revolutionize next-generation displays and electronic devices. The project was a collaborative effort with Professors Ao Liu and Huihui Zhu from the University of Electronic Science and Technology of China (UESTC), and the findings were published in Nature Electronics on April 28th.   Every time we stream videos or play games on our smartphones, thousands of transistors operate tirelessly ...

Sunlight unlocks secrets to how Earth works

2025-05-07
When our planet and the incoming sunlight align just right, stunning phenomena such as rainbows and halos can occur. More often, sunlight - or shortwave radiation - interacts with Earth in subtle but curious ways.   A new perspective study, published in Advances in Atmospheric Sciences, lays out how shortwave radiation research has led to improved fundamental understanding of Earth. The study also shares exciting prospects for how such advances can continue into the future. Scientific insights derived from shortwave ...

A healthy diet in childhood is linked to starting menstrual periods later, regardless of BMI or height

2025-05-07
Eating a healthy diet as a child is linked to girls having their first menstrual period at an older age than those who consumed a less healthy diet, according to a new study published today (Wednesday) in Human Reproduction [1], one of the world’s leading reproductive medicine journals. The findings remained unaltered by the girls’ body mass index (BMI) or height, both of which have been associated with the earlier onset of periods. The study has implications for health in later life as it is well known that women who started their periods at an early age may be at higher risk for diabetes, ...
