A new NIH study finds that elevated stress hormones in diabetic rodents disrupt hippocampal function, leading to learning and memory deficits. Normalizing stress hormone levels reverses the negative impact and restores learning and memory.
Experts emphasize the need for global solutions to manage carbon emissions, considering the global energy system's shift and technological advancements. Accurate modeling of Earth's systems, capturing and storing CO2 are critical challenges.
Researchers suggest diversifying local ecosystems to increase resilience against climate change impacts. Local policies focus on adaptation rather than mitigation, according to Charles Perrings' research based on the Millennium Ecosystem Assessment.
A Harvard University scientist has synthesized four key differences in human and animal cognition into a hypothesis on what exactly differentiates human and animal thought. The theory of
Klaus Keller's research suggests that the North Atlantic meridional overturning circulation (MOC) may respond to human-made greenhouse gas emissions in a threshold response. Improved MOC observation systems could provide an early warning of an approaching collapse, enabling more effective climate policies.
The study proposes antimicrobial cycling and patient isolation as effective strategies to curb dual-resistant bacteria in hospitals. The model's results indicate that these methods can reduce the prevalence of dual resistance, making them crucial in combating the growing threat of superbugs.
Researchers at Penn State have developed a proof-of-concept device that can split water and produce recoverable hydrogen using sunlight. The system, which uses a catalyst complex to mimic natural photosynthesis, achieves an efficiency of about 0.3 percent but holds promise for future improvements.
Kenneth Miller, a renowned biologist, will argue at the AAAS symposium that science is grounded in the idea of 'design', highlighting the correlation between structure and function. He suggests that embracing this concept can help reclaim the language of design and make science more appealing to those seeking meaning.
Astronomers have discovered that many nearby sun-like stars may form rocky planets, with potential for life being more common than thought. The study suggests that at least 20 percent to 60 percent of stars similar to the sun are candidates for forming terrestrial worlds.
A new mathematical model has identified minimizing antibiotic treatment duration as the optimal strategy for controlling hospital-borne antibiotic-resistant bacteria epidemics. By starting treatments early and administering drugs for shorter periods, the risk of cross-infection by resistant bacteria can be significantly reduced.
Uninsured and Medicaid-insured US patients are more likely to present with advanced cancer at diagnosis than privately insured patients. The authors found that these disparities affect ethnic minorities and cancers with early detection potential, underscoring the need for adequate healthcare coverage.
Rising greenhouse gas emissions are causing ocean warming, acidification, and altering circulation patterns, posing significant threats to coral reefs and other marine ecosystems. The panelists emphasize the need for drastic action to reduce emissions to mitigate these impacts.
Physicist John Negele will discuss how quarks and gluons interact using lattice field theory on supercomputers. The tiny particles behave differently than larger particles, requiring a unique approach to study them.
Heather Leslie explains how resilience science can inform conservation efforts, recognizing connections between human communities and marine ecosystems. Her work shows promise in the Chesapeake Bay restoration project, where oyster sanctuaries and eelgrass seeding increase future resilience.
Noted UNH oceans expert Andrew A. Rosenberg will address the issue of how to protect and manage ocean resources at this year's American Association for the Advancement of Science annual meeting. He emphasizes the need to learn from past mistakes and adopt new approaches such as ecosystem-based management.
A novel mathematical model predicts a rise in drug-resistant HIV infections among men in San Francisco, but surprisingly reduces the epidemic's severity. The Amplification Cascade Model suggests that resistance to certain classes of drugs will decline, while others will rise, leading to less infectious strains.
A Dutch study found that only 17% of individuals who survive pediatric cancer receive follow-up care at age 35, highlighting the need for family doctors to be involved. The study suggests that shared care between dedicated clinics and family practitioners can increase surveillance for adverse effects.
A multidisciplinary symposium will address evidence of paternal exposure to toxins affecting fetal development, producing deficits in offspring, and expressing in subsequent generations. The event aims to raise awareness and stimulate research on the significant impact of male parents on reproductive success.
Researchers have speculated that the Foxp2 gene is linked to language ability, but MIT's Robert Berwick argues this connection is unlikely due to complexity and speculative chain of events. Language is likely the result of a subtle interplay among various factors, making direct genetic connections impossible.
Scientists are using integrated ecosystem assessments to prioritize strategies for restoring Puget Sound's ecosystem. Increasing salmon production can have negative impacts on wild Chinook salmon populations, highlighting the need for balanced management approaches.
Researchers found that muscle cells play a vital role in communicating with neurons, and when this communication is disrupted, it can lead to nerve problems. The study provides new insights into the development of neuromuscular diseases such as muscular dystrophy and ALS.
Ecological balance diverges across cultural, economic and political perspectives, according to ASU researcher Ann Kinzig. The biosphere can be both robust and fragile, with instability in one part required for stability in another.
A recent global assessment by the World Conservation Union has found that many large shark species have declined by more than half due to increased demand for shark fins and meat, as well as recreational and commercial fisheries. The scalloped hammerhead shark is among those listed as globally endangered on the IUCN Red List.
Studies show people overestimate enjoyment of experiences with better alternatives and underestimate with worse ones. Slowing down experiences allows minds to wander to alternative options, leading to more accurate predictions.
Scientists warn that small sea creatures like pteropods, which are eaten by many species, may go extinct due to ocean acidification and warming. This could have catastrophic effects on the food chain, as these organisms play a vital role in marine ecosystems.
A new study found that uninsured patients are more likely to be diagnosed with advanced stage cancer compared to those with private insurance. The study, which analyzed over 3.5 million cancer patients, also showed that Medicaid-insured patients face similar risks, particularly for cancers with early detection methods.
Researchers have discovered critical details of shark behavior, including migration routes and gathering sites. The findings suggest that open-ocean sharks are particularly threatened from overfishing, and that some species congregate at established 'stepping stone' sites, which can help inform conservation efforts.
