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.


BPA replacements in plastics cause reproductive problems in lab mice



Posted: 13 Sep 2018 08:39 AM PDT


Twenty years ago, researchers made the accidental discovery that BPA had leached out of plastic cages used to house female mice in the lab, causing an increase in chromosomally abnormal eggs. Now, the same team is back to report that the array of alternative bisphenols now used to replace BPA in BPA-free bottles, cups, cages, and other items appear to come with similar problems for their mice.


People show confirmation bias even about which way dots are moving



Posted: 13 Sep 2018 08:39 AM PDT


People have a tendency to interpret new information in a way that supports their pre-existing beliefs, a phenomenon known as confirmation bias. Now, researchers have shown that people will do the same thing even when the decision they've made pertains to a choice that is rather less consequential: which direction a series of dots is moving and whether the average of a series of numbers is greater or less than 50.


Eyes have a natural version of night vision



Posted: 13 Sep 2018 08:39 AM PDT


To see under starlight and moonlight, the retina of the eye changes both the software and hardware of its light-sensing cells to create a kind of night vision. Retinal circuits that were thought to be unchanging and programmed for specific tasks actively adapt to different light conditions, say the scientists who made the discovery.


New means to fight 'un-killable' bacteria in healthcare settings



Posted: 13 Sep 2018 08:38 AM PDT


Scientists have identified new means of fighting drug-tolerant bacteria, a growing global threat as menacing as drug-resistant microbes. Little is known about the mechanisms leading to tolerance, a strategy that makes bacteria 'indifferent' to antibiotics and almost 'un-killable,' which results in chronic infections extremely difficult to treat and cure.


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.


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.


Gut bacteria's shocking secret: They produce electricity



Posted: 12 Sep 2018 10:34 AM PDT


To date, most electricity-generating bacteria have come from weird environments, but researchers have found more than 100 in the human microbiome, both pathogenic and probiotic. They were unsuspected because they employ a different and simpler extracellular electron transfer system, which may prove useful in creating bacterial batteries. Their electrogenic ability may be important in infectivity, or in how they ferment cheese and yogurt.


Human gut study questions probiotic health benefits



Posted: 06 Sep 2018 11:16 AM PDT


New research suggests that probiotics might not be as effective as we think. Through a series of experiments looking inside the human gut, researchers show that many people's digestive tracts prevent standard probiotics from successfully colonizing them.
