Fire ecologists and wildlife specialists at La Trobe University have made key discoveries in how wildlife restores itself after bushfires, and what conservationists can do to assist the process.
Debates over gun regulations make headlines across the world, but there's an underground operation for weapons that has drawn very little attention -- until now. Researchers from Michigan State University crept into the dark web to investigate how firearms are anonymously bought and sold around the world.
Bureaucratic quality in developing countries is endangered by the structural adjustment programs imposed by the international financial institutions, a paper by Bocconi's Alexander Kentikelenis and colleagues, in the American Journal of Sociology, states. In particular, the IMF's structural reforms mandating privatization, price deregulation, and reductions in public sector employment jeopardize state capacity by compromising the healthy relationship between state and business, as in uncertain times bureaucrats are more likely to fall prey to private interests.
What will a three-degree-warmer world look like? When experiencing stress or damage from various sources, plants use chloroplast-to-nucleus communication to regulate gene expression and help them cope. Now, Salk Institute researchers have found that GUN1 -- a gene that integrates numerous chloroplast-to-nucleus retrograde signaling pathways -- also plays an important role in how proteins are made in damaged chloroplasts, which provides a new insight into how plants respond to stress.
Researchers at the University of California, Davis, recently investigated levels of methylmercury in a small sampling of commercial dog foods and found good news for dog owners. Of the 24 diets tested, only three were positive for low concentrations of total mercury, and only one of those contained detectable methylmercury.
Researchers use GPS to track the timing and patterns of giant tortoise migration over multiple years. The tortoises often take the same migration routes over many years in order to find optimal food quality and temperatures. The timing of this migration is essential for keeping their energy levels high, and climate change could disrupt a tortoise's ability to migrate at the right time.
The brain is more resilient than previously thought. In a groundbreaking experiment published in this week's issue of Nature, neuroscientists created an artificial circulation system that successfully restored some functions and structures in pig brains. The result challenges the notion that mammalian brains are fully and irreversibly damaged by a lack of oxygen.
A new study suggests reefs suffering coral bleaching can still be productive, as fish dependent on reefs get a bulk of their food delivered via the currents flowing past.
The CRISPR Journal announces the publication of its April 2019 issue. The Journal is dedicated to validating and publishing outstanding research and commentary on all aspects of CRISPR and gene editing, including CRISPR biology, technology, and genome editing, and commentary and debate of key policy, regulatory, and ethical issues affecting the field.
Harmonization method developed to reduce site-related differences between neuroimaging data from individual imaging sites and publicly released big data of multiple psychiatric disorders from many imaging sites.
