Investing in love and affection pays off for species that mate for life
Tracking lead levels in soil over time is critical for cities to determine lead contamination risks for their youngest and most vulnerable residents, according to a new Tulane University study published in the Proceedings of the National Academy of Sciences.
New environment laws in Queen's speech
The males of species that form long-lasting pair-bonds, like many birds, often continue to make elaborate displays of plumage, colors and dances after they mate with a female. While their time and energy might be better spent taking care of their offspring, these displays also encourage the female to invest more of their energy into the brood.
Renewables overtake hydrocarbons in UK electricity generation: study
Crime and health take centre stage, but opposition parties dismiss the programme as "election manifesto".
Could cricket and worm burgers help save the planet?
Renewable sources generated more of Britain's electricity than fossil fuels for the first time last quarter, according to analysis by specialist website "Carbon Brief" published Monday. "In the third quarter of 2019, the UK's windfarms, solar panels, biomass and hydro plants generated more electricity than the combined output from power stations fired by coal, oil and gas," said the website. "During the three months of July, August and September, renewables generated an estimated total of 29.5 terawatt hours (TWh), compared with just 29.1TWh from fossil fuels," it added.
Sensory and motor brain plasticity is not limited by location
Insects are being touted as an eco-friendly protein source, but do bug burgers pass the taste test?
Not cross bunnies: can a pet rabbit ever be happy?
The new function of unused cortical regions is not necessarily determined by the function of nearby cortical regions, according to new research in adults born without one hand.
Finding joy in the 'blue hour': A photographer's ocean eye candy is on display in Quebec
A study of more than 6,000 rabbits treated by vets has found that many lead sad lives. Here’s how to make sure they stay healthy and avoid loneliness
There are thought to be more than 1.5m pet rabbits in the UK, and a large proportion of them could be leading very sad lives. A study of more than 6,000 rabbits treated by vets found alarming health conditions such as overgrown nails and teeth, digestive problems and skin issues.
Thanks to generations of stories featuring rabbits, and their sweet, cuddly appearance, they have long been a popular children’s pet but, says Dan O’Neill, senior lecturer in companion animal epidemiology at the Royal Veterinary College, and co-author of the study, “they are not a good child’s pet at all.” They are a prey animal – constantly alert to danger – so being handled by a noisy child can be stressful, especially if they are not used to it (if a child, say, only plays with the rabbit at the weekend).

Unlocking the biochemical treasure chest within microbes
When photographer Michael Winsor has his camera in hand, his ideal place to be is on the Atlantic Ocean.
Air pollution linked to 'missed' miscarriages in China: study
An international team of scientists has developed a genetic engineering tool that makes producing and analyzing microbial secondary metabolites -- the basis for many important agricultural, industrial, and medical products -- easier than ever before, and could even lead to breakthroughs in biomanufacturing.
Air pollution linked to 'missed' miscarriages in China: study
Exposure to airborne pollutants increases the risk of "missed" miscarriages in which a fetus dies without a pregnant woman experiencing any noticeable symptoms, researchers said Monday.
Scientists help immune system find hidden cancer cells
Exposure to airborne pollutants increases the risk of "missed" miscarriages in which a fetus dies without a pregnant woman experiencing any noticeable symptoms, researchers said Monday. Previous studies have shown a correlation between air pollution and pregnancy complications, but the new research -- published in Nature Sustainability journal by a team of researchers from Chinese universities -- sheds light on a little-studied impact of pollution. The study found that exposure to higher concentrations of airborne particulate matter, as well as sulfur dioxide, ozone and carbon monoxide, was associated with a higher risk of missed miscarriage in the first trimester of pregnancy.
Lakes worldwide are experiencing more severe algal blooms
Cancer cells are masters at avoiding detection, but a new system can make them stand out from the crowd and help the immune system spot and eliminate tumors that other forms of immunotherapies might miss.
Women have substantially less influence on Twitter than men in academic medicine
The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes. Researchers used 30 years of data from the Landsat 5 near-Earth satellite and created a partnership with Google Earth Engine to reveal long-term trends in summer algal blooms in 71 large lakes in 33 countries on six continents.
Microbleeds may worsen outcome after head injury
Women who are health policy or health services researchers face a significant disparity in social media influence compared to their male peers, according to a new study. Although the average number of tweets among all researchers tend to be consistent, women trail behind men in follower counts, regardless of how active they are on Twitter.
How mucus tames microbes
Using advanced imaging, researchers have uncovered new information regarding traumatic microbleeds, which appear as small, dark lesions on MRI scans after head injury but are typically too small to be detected on CT scans. The findings published in Brain suggest that traumatic microbleeds are a form of injury to brain blood vessels and may predict worse outcomes. The study was conducted in part by scientists at the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.
How to control friction in topological insulators
New research reveals that glycans -- branched sugar molecules found in mucus -- can prevent bacteria from communicating with each other and forming infectious biofilms, effectively rendering the microbes harmless.
Researchers explore spinal discs' early response to injury and ways to improve it
Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report.
The nano-guitar string that plays itself
Researchers showed in animal models that the default injury response of spinal discs can be temporarily stopped to allow for better treatment.
Dementia spreads via connected brain networks
Scientists have created a nano-electronic circuit which vibrates without any external force. Just as a guitar string vibrates when plucked, the wire -- 100,000 times thinner than a guitar string -- vibrates when forced into motion by an oscillating voltage. The surprise came when they repeated the experiment without the forcing voltage. Under the right conditions, the wire oscillated of its own accord. The nano-guitar string was playing itself.
Shipment tracking for 'fat parcels' in the body
Scientists used maps of brain connections to predict how brain atrophy would spread in individual patients with frontotemporal dementia (FTD), adding to growing evidence that the loss of brain cells associated with dementia spreads via the synaptic connections between established brain networks.
Evolutionary history of oaks
Without fat, nothing works in the body: These substances serve as energy suppliers and important building blocks -- including for the envelopes of living cells. Numerous diseases are related to disorders in the fat metabolism, such as obesity or cancer. Researchers are now demonstrating how the fat metabolism can be monitored down to the individual liver cell of a mouse with the greatest sensitivity.
Unique sticky particles formed by harnessing chaos
Oaks have a complex evolutionary history that has long eluded scientists. New research, however, provides the most detailed account to date of the evolution of oaks, recovering the 56-million-year history that has made the oaks one of the most diverse, abundant and important woody plant groups to the ecology and economy of the northern hemisphere.
Scientists pinpoint cause of harmful dendrites and whiskers in lithium batteries
New research shows that unique materials with distinct properties akin to those of gecko feet - the ability to stick to just about any surface -- can be created by harnessing liquid-driven chaos to produce soft polymer microparticles with hierarchical branching on the micro- and nanoscale.
Scientists have uncovered a root cause of the growth of needle-like structures -- known as dendrites and whiskers -- that plague lithium batteries, sometimes causing a short circuit, failure, or even a fire. Such defects are a major factor holding back the batteries from even more widespread use and further improvement.
