Sniffing out error in detection dog data



Posted: 14 Sep 2018 07:04 AM PDT


New research finds three alternative answers beyond errors in handler or dog training that can explain why dogs trained to identify scat for conservation purposes sometimes collect non-target scats.


The walking dead: Fossils on the move can distort patterns of mass extinctions



Posted: 14 Sep 2018 07:03 AM PDT


Using the fossil record to accurately estimate the timing and pace of past mass extinctions is no easy task, and a new study highlights how fossil evidence can produce a misleading picture if not interpreted with care.


Gut microbes' role in mammals' evolution starts to become clearer



Posted: 14 Sep 2018 05:48 AM PDT


Scientists have made a key advance toward understanding which of the trillions of gut microbes may play important roles in how humans and other mammals evolve.


Geologists reveal ancient connection between England and France



Posted: 14 Sep 2018 05:48 AM PDT


The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research.


Trees reveal the evolution of environmental pollution



Posted: 13 Sep 2018 11:20 AM PDT


Chemical analysis of tipuana tree rings and bark by Brazilian researchers shows falling levels of heavy metal pollution in the air of São Paulo City, Southern Hemisphere's largest metropolis.


Most fire in Florida goes undetected



Posted: 13 Sep 2018 10:45 AM PDT


A new study indicates that common satellite imaging technologies have vastly underestimated the number of fires in Florida, detecting only 25 percent of burned area.


Conservation dairy farming could help Pa. meet Chesapeake target



Posted: 13 Sep 2018 10:45 AM PDT


If the majority of dairy farms in Pennsylvania fully adopt conservation best-management practices, the state may be able to achieve its total maximum daily load water-quality target for the Chesapeake Bay, according to researchers.


Mixed chemicals in beauty products may harm women's hormones



Posted: 13 Sep 2018 10:45 AM PDT


Researchers have discovered links between chemicals that are widely used in cosmetic and personal care products and changes in reproductive hormones.


Appetite for shark fin soup serious risk to threatened sharks



Posted: 13 Sep 2018 08:38 AM PDT


Fishing pressure on threatened shark populations has increased dramatically in recent years and it is urgent that consumers reject shark fin products altogether, new study asserts.


Heat-related deaths likely to increase significantly as global temperatures rise, warn researchers



Posted: 13 Sep 2018 05:21 AM PDT


In a new article, experts argue that the world needs to keep global temperatures in check by meeting the goals set out in the Paris Agreement, or more people could die because of extreme temperatures.


Rural and urban communities need different policies to boost economic mobility



Posted: 12 Sep 2018 10:35 AM PDT


The farther away from a city a person is raised, the more likely they are to climb the economic ladder, according to economists, who also found that community characteristics associated with upward mobility actually have different effects in rural and urban locations.


The world needs death and decomposition



Posted: 12 Sep 2018 10:35 AM PDT


Thanks to a new study, scientists now have a better way to investigate decomposing plants' and animals' contributions to the ecosystem.


Air purifiers may benefit fetal growth



Posted: 12 Sep 2018 10:35 AM PDT


A new study reveals fetal growth may improve if pregnant women use portable air purifiers inside their homes.


Halting biodiversity loss: Political actions are required, not additional scientific knowledge



Posted: 12 Sep 2018 10:35 AM PDT


Over 15 years, almost 13,000 scientific papers have been published in the leading conservation science journals. Yet biodiversity remains threatened at a global scale. Researchers have now focused on this worrisome paradox by taking a deeper look at this large volume of literature. One of the major problems is that decisions are usually more favorable to human activities than to nature protection.


Fire weather prediction improving



Posted: 12 Sep 2018 10:27 AM PDT


Scientists have created a new fire-weather prediction tool that works with the same weather models that are used every day in fire weather forecasts, and thus can be applied anywhere in the world, regardless of fuel conditions or topography.
