As they are in many places around the globe, glaciers perched high in the Andes Mountains are shrinking. Now, researchers have uncovered evidence that the high-altitude tropical ice fields are likely smaller than they've been at any time since the last ice age ended 11,700 years ago.
Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our understanding of planetary systems.
Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
For those aged 50 and above, keeping your mind sharp is not just about memory. Overall well-being and quality of life are key factors of wellness and brain health. Brain health encompasses a wide range of factors, from cognitive function to emotional balance. It is a crucial part of maintaining independence and enjoying the golden years. By focusing on six key areas, there are practical steps you can take to enhance brain health and improve mental well-being.
TFAH is a non-profit, non-partisan organization that promotes optimal health for every person and community and makes the prevention of illness and injury a national priority. TFAH is committed to making prevention and health equity foundational to policymaking at all levels of society. Some focus areas at TFAH include public health funding and infrastructure, public health preparedness, obesity, health equity, substance misuse and suicide, and population health.
What if the 'Market Economy' always existed? Archaeologists tried to answer this question by researching how much Bronze Age people used to spend to sustain their daily lives. Their results show that, starting at least 3,500 years ago, the spending habits of prehistoric Europeans were not substantially different from what they are today.
Providers, dispensers and state governments utilizing prescription drug monitoring programs (PDMPs) can face challenges in building comprehensive views of controlled substance use. As the opioid epidemic continues to evolve, the solutions that states and providers are using to combat it must also evolve to keep communities safe and prevent further incidences of substance use disorder (SUD).
“ Many of the public health challenges faced today are global health problems and require an understanding of the global dimensions of health and its influences. Public health professionals need an understanding of the global influences on health to be able to improve the health of the population.” – Public Health Specialty Training Curriculum 2022 Demand for global public health training opportunities is high, with many registrars wishing to undertake a global health placement either in t
Photovoltaic (PV) technologies, which convert light into electricity, are increasingly applied worldwide to generate renewable energy. Researchers have now developed a molecular treatment that significantly enhances the efficiency and durability of perovskite solar cells. Their breakthrough will potentially accelerate the large-scale production of this clean energy.
The Network for Public Health Law (the Network) has released a guide on “Law and Policy Considerations for Workforce Protections from Extreme Heat,” detailing federal, state, and local legal and policy protections for both indoor and outdoor workers exposed to extreme heat on the job. The guide also addresses significant barriers to safeguarding this workforce, including the legal doctrine of preemption, which allows higher levels of government to limit the authority of lower levels; and provide
Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 C of global warming after a period of overshoot. A new study indicates that this risk can be minimized if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers write.
Public health, explained: Sign up to receive Healthbeat’s free national newsletter here. A new study lends weight to fears that more livestock workers have gotten the bird flu than has been reported. “I am very confident there are more people being infected than we know about,” said Gregory Gray, the infectious disease researcher at the University of Texas Medical Branch who led the study, posted online Wednesday and under review to be published in a leading infectious disease journal.
Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the first time a molecular complex -- called CTF18-RFC in humans and Ctf18-RFC in yeast -- that loads a 'clamp' onto DNA to keep parts of the replication machinery from falling off the DNA strand.
Scientists have devised an innovative imaging method using state-of-the-art microscopes that significantly reduces the time and radiation required. Their work represents a significant breakthrough that will benefit several disciplines, from materials science to medicine, as the method promises to deliver improved imaging for sensitive materials such as biological tissues that are especially vulnerable to damage.
