Researchers found that heat stress, measured by temperature-humidity index (THI), was a significant factor in low conception rates of dairy herds. High THI values before insemination, particularly on Day 3, led to ovulation failure and reduced fertility. Conversely, cooling measures implemented when temperatures exceeded 20°C improved ...
Researchers studying 523 pairs of twins aim to understand the role of environmental stress in cardiovascular disease and type II diabetes. The study, funded by a $1.7 million grant, will evaluate twins' living environments and stress coping mechanisms over four years.
Researchers developed a self-test tool using data from an undersea mission to assess stress, fatigue and cognitive fitness in astronauts. The test involves a vigilance task and cortisol measurements to evaluate the effects of prolonged space missions on mental performance.
A recent study finds that human population size and affluence are the primary drivers of environmental stressors, whereas urbanization, economic structure, and age of population have limited impact. The researchers used global average productivity to compare environmental tradeoffs and human-induced stressors in the environment.
A recent study found that climate change impacts mussels beyond their northern and southern range limits, with temperature variations affecting thermal stress in the rocky intertidal zone. The research suggests conserving areas based on traditional methods may not be enough to protect mussel populations.
Research on civil servants reveals that high job demands and low workplace support are key factors contributing to sick building syndrome symptoms. Physical building attributes have a small influence on symptoms, suggesting that poor psychosocial conditions play a significant role.
A new study by Ohio University's Molly Morris and colleagues found that older female swordtail fish spend more time with asymmetrical males than symmetrical males. This contradicts previous studies suggesting females prefer symmetrical markings as a sign of genetic fitness.
The University of Ulster team found significantly increased levels of stress on two fault zones in Indonesia, including the Sunda trench and Sumatra fault. The analysis suggests a high risk of another earthquake, potentially triggering another tsunami.
Dietmar Kueltz's team discovered genetic switches that enable certain fish to thrive in both freshwater and saltwater environments. These switches, involving transcription factors, allow the fish to resist stress and potentially survive other environmental challenges like climate change.
The 2005 Environmental Sustainability Index (ESI) ranks countries on 21 elements of environmental sustainability. Finland scores highest, performing well on issues like air pollution and global-scale environmental efforts, while the US ranks 45th due to weaker performance on waste generation and greenhouse gas emissions.
Researchers will model the behavior of individual atoms to gain a better understanding of stress corrosion cracking in metals. The goal is to prevent damage and create more corrosion-resistant materials, leading to safer structures and potentially even improved comfort for travelers.
A twelve-year longitudinal study found that personality and learning style are key predictors of doctors' burnout and stress. Doctors with high neuroticism and lower conscientiousness tend to experience more burnout.
Researchers at University at Buffalo found that corals can take up new algal symbionts from their environments, increasing cell densities and demonstrating a mechanism for recovery from bleaching. This study provides evidence of coral resilience in the face of environmental change.
Researchers discover tiny microbes in ancient Greenland glacier that are smaller than common bacteria and can survive extreme conditions. These ultra-small cells have been found to be among the uncultured majority of microbes on Earth and hold secrets to their survival mechanisms.
Scientists have found microscopic life in ancient glacier ice, sparking interest in survival mechanisms of small cells under harsh conditions. The discovery opens up new avenues for research into growing previously unculturable organisms and understanding the limits of microbial life.
A Canadian researcher finds a strong link between sea lice from salmon farms and declining native salmon populations in BC. Meanwhile, an opposing expert suggests other factors are at play and that correlation does not necessarily imply causation.
A gene variant appears to increase the risk of depression following stressful life events, according to a new study. People with the short version of the serotonin transporter gene were more likely to develop depression if they experienced multiple stressful life events.
Scientists from University of Ulster's Geophysics Research Group warn of substantial loss of life possible in Bingol city after Thursday's earthquake, citing increased seismic risk. The team identified two highly stressed areas on the East Anatolian Fault Zone as most likely locations for future large events.
A study published in Environment and Behavior found that rural children living in homes with more nature exhibits lower levels of psychological distress. The researchers also discovered that the benefits of exposure to natural environments are not limited, even in rural settings with abundant green landscapes.
Researchers at Purdue University have discovered a crucial protein family in plants that helps them adapt to stressful conditions. The AtCPL family, which controls gene activation, plays a vital role in regulating plant responses to environmental stresses such as salinity, cold, and drought.
A new study confirms that global warming is affecting Earth's species worldwide, causing disruptions to animals and plants. The research found that even small changes in temperature have significant effects on ecosystems, leading to species migration, breeding, and population shifts.
