When more women are involved in group decisions about land management, the group conserves more - particularly when offered financial incentives to do so, according to a new University of Colorado Boulder study published this week in Nature Climate Change.
A world free of tuberculosis (TB) is possible by 2045 if increased political will and financial resources are directed towards priority areas including providing evidence-based interventions to everyone, especially to high risk groups, and increasing research to develop new ways to diagnose, treat, and prevent TB. Funding this response will require substantial investments, and accountability mechanisms will be necessary to ensure that promises are kept and targets are reached.
Modern analytical tools like mass spectrometers can identify many unknown substances, allowing scientists to easily tell whether foods or medicines have been altered. However, the cost, size, power consumption and complexity of these instruments often prevent their use in resource-limited regions. Now, in ACS Central Science, researchers report that they have developed a simple, inexpensive method to identify samples by seeing how they react to a change in their environment.
New or upgraded roads in the Greater Serengeti Ecosystem around Serengeti National Park will not reduce growing pressure on the ecosystem, a study shows.
Academics led by Professor Lucie Cluver at Oxford University have shown how key services in lower and middle-income countries can contribute to multiple sustainable development goals (SDGs), even for the highest-risk children and adolescents.
A new paper published in the Review of Economic Studies finds that US counties with more historical immigration have higher incomes, less poverty, and lower unemployment today.
At what age do you feel 65? New study reveals wide variations in how well or poorly people age. A 30-year gap separates countries with the highest and lowest ages at which people experience the health problems of a 65-year-old, according to a new scientific study. Researchers found 76-year-olds in Japan and 46-year-olds in Papua New Guinea have the same level of age-related health problems as an 'average' person aged 65.
A new study of animal populations inside and outside a protected area in Senegal, Niokolo-Koba National Park, shows that protecting such an area from human interaction and development preserves not only chimps but many other mammal species.
A new study co-authored by an MIT economist shows that when it comes to growth, democracy significantly increases development. Indeed, countries switching to democratic rule experience a 20 percent increase in GDP over a 25-year period, compared to what would have happened had they remained authoritarian states, the researchers report.
Beth Parks has devised an astonishingly simple way to overcome a limitation of solar cells -- a bucket of water. As she will describe at the 2019 APS March Meeting, she developed a frame that holds the solar cell with a bucket suspended on either end. By controlling the leak of water from one of the buckets, the solar cell shifts, tracking the arc of the sun throughout the day.
