A growing body of research shows that birds' spring migration has been getting earlier and earlier in recent decades. New research from The Auk: Ornithological Advances on Black-throated Blue Warblers, a common songbird that migrates from Canada and the eastern US to Central America and back every year, uses fifty years of bird-banding data to add another piece to the puzzle, showing that little-studied fall migration patterns have been shifting over time as well.
Employing a game theory model, University of Pennsylvania researchers demonstrate how strategic decisions influence the environment in which those decisions are made, alterations which in turn influence strategy. Their analysis, which identifies how incentives can tip a strategy from one extreme to another, applies to fields as diverse as fisheries dynamics to climate change policy.
The researchers tricked photons - which are intrinsically non-magnetic - into behaving like charged electrons. They accomplished this by sending the photons through carefully designed mazes in a way that caused the light particles to behave as if they were being acted upon by what the scientists called a "synthetic" or "artificial" magnetic field.
First evidence that animal DNA methylation patterns can be passed to the next generation.
Texas teens lost access to confidential family planning services due to family planning budget cuts and loss of Title X funds, says a new study led by the University of Colorado College of Nursing just published in the Journal of Adolescent Health. This research suggests that contraception access for teens throughout the nation could worsen as new changes to Title X are implemented.
New research has identified a clear accountability gap in the current Freedom of Information (FOI) legislation when it comes to outsourced public services. The research, which focused on outsourcing through Private Finance Initiative (PFI), found high levels of non-disclosure due either to refusal/partial refusal or non-response to FOIs.
Ecological niches are a concept well known from higher animals. Apparently, bacteria act accordingly. Researchers from the Max-Planck-Institute for Marine Microbiology in Bremen have found that marine Polaribacter bacteria find their ecological niche by specializing on their favorite sugar. They now present their results in ISME Journal.
Researchers used 'dual-anonymization' techniques to close the gender gap around who gets time on the Hubble Space Telescope.
Policies regulating fishing in international waters do not sufficiently protect officials who monitor illegal fishing, the prohibited dumping of equipment, or human trafficking or other human rights abuses, finds a new analysis by a team of environmental researchers.
No single country is adequately protecting children's health, their environment and their futures, finds a landmark report released today by a Commission of over 40 child and adolescent health experts from around the world. The Commission was convened by the World Health Organization (WHO), UNICEF and The Lancet.
