Ancient volcanoes once boosted ocean carbon, but humans are now far outpacing them
- ScienceDaily
- 20/9/14 23:29
A new study of an ancient period that is considered the closest natural analog to the era of modern human carbon emissions has found that massive volcanism sent great waves of carbon into the oceans over thousands of years -- but that nature did not come close to matching what humans are doing today.
Predicting the slow death of lithium-ion batteries
- ScienceDaily
- 20/9/14 23:29
A new model offers a way to predict the condition of a battery's internal systems in real-time with far more accuracy than existing tools. In electric cars, the technology could improve driving range estimates and prolong battery life.
Human activities promote disease-spreading mosquitoes; more study needed for prevention
- ScienceDaily
- 20/9/14 23:29
Disease-spreading mosquitoes may be more likely to occupy areas impacted by human activities like pesticide use and habitat destruction, than they are areas less disturbed by humans, a recent study found.
New rules for algae species classification

A team of evolutionary biologists and ecologists has a new idea for how scientists should classify algae species.
Virtual reality trains public to reverse opioid overdoses
- ScienceDaily
- 20/9/14 22:07
The United States has seen a 200% increase in the rate of deaths by opioid overdose in the last 20 years. But many of these deaths were preventable. Naloxone, also called Narcan, is a prescription drug that reverses opioid overdoses, and in more than 40 states there is a standing order policy, which makes it available to anyone, without an individual prescription from a healthcare provider.
The two cultures within science outlined

Researchers trace the outlines of two cultures within science, one of which promotes greater equity and inclusivity.
Gene-edited livestock 'surrogate sires' successfully made fertile
- ScienceDaily
- 20/9/14 22:07
For the first time, scientists have created pigs, goats and cattle that can serve as viable 'surrogate sires,' male animals that produce sperm carrying only the genetic traits of donor animals. The advance could speed the spread of desirable characteristics in livestock and improve food production for a growing global population.
Antarctica: Cracks in the ice
- ScienceDaily
- 20/9/14 21:11
West Antarctica's Pine Island Glacier and Thwaites Glacier have been undergoing rapid changes, with potentially major consequences for rising sea levels. However, the processes that underlie these changes and their impact on these ice sheets have not been fully charted. One of these processes has now been described in detail: the emergence and development of damage/cracks in part of the glaciers...
How the brain creates the experience of time
- ScienceDaily
- 20/9/14 19:19
On some days, time flies by, while on others it seems to drag on. A new study from JNeurosci reveals why: time-sensitive neurons get worn out and skew our perceptions of time.
Dams exacerbate the consequences of climate change on river fish
- ScienceDaily
- 20/9/14 19:19
A potential response of river fish to environmental changes is to colonize new habitats. But what happens when dams and weirs restrict their movement? And are native and alien species similarly affected?
Immune system affects mind and body, study indicates
- ScienceDaily
- 20/9/14 19:19
Researchers have discovered that a molecule produced by the immune system acts on the brain to change the behavior of mice.
Botox for TMJ disorders may not lead to bone loss in the short term, but more research is needed
- ScienceDaily
- 20/9/14 19:19
Botox injections to manage jaw and facial pain do not result in clinically significant changes in jaw bone when used short term and in low doses, according to researchers. However, they found evidence of bone loss when higher doses were used.
ARPA-type funding gives green technology an 'innovation advantage', study finds
- ScienceDaily
- 20/9/14 17:59
Startups funded by the U.S. agency ARPA-E file patents at twice the rate of similar cleantech firms. The United Kingdom should trial its own climate-focused ARPA as part of COVID-19 recovery package, argue experts.
New method to design diamond lattices and other crystals from microscopic building blocks
- ScienceDaily
- 20/9/14 17:59
Researchers describe a technique for using LEGO®-like elements at the scale of a few billionths of a meter. Further, they are able to cajole these design elements to self-assemble, with each LEGO® piece identifying its proper mate and linking up in a precise sequence to complete the desired nanostructure.
Global study reveals time running out for many soils, but conservation measures can help
- ScienceDaily
- 20/9/14 17:59
Researchers found more than 90 per cent of the conventionally farmed soils in their global study were thinning, and 16 per cent had lifespans of less than a century. These rapidly thinning soils were found all over the world, including countries such as Australia, China, the UK, and the USA.
Doctors get plenty of advice on starting treatment; this could help them know when to stop
- ScienceDaily
- 20/9/14 17:59
Decades of effort have improved the chances that patients will get the scans, routine tests and medicines that can do them the most good - and avoid the ones that won't help them at all. But in the push toward evidence-based medicine, a new study says, a key step has mostly gotten overlooked: helping doctors stop or scale back - or deintensify - treatment once it has started.
Substance use disorders linked to COVID-19 susceptibility
- ScienceDaily
- 20/9/14 17:59
A recent study found that people with substance use disorders (SUDs) are more susceptible to COVID-19 and its complications. The findings suggest that health care providers should closely monitor patients with SUDs and develop action plans to help shield them from infection and severe outcomes.
Structure of ATPase, the world's smallest turbine, solved
- ScienceDaily
- 20/9/14 17:41
The chemical ATP, adenosine triphosphate, is the fuel that powers all life. Despite ATP's central role, the structure of the enzyme generating ATP, F1Fo-ATP synthase, in mammals, including humans, has not been known so far. Now, scientists report the first complete structure of the mammalian F1Fo-ATP synthase. This structure also settles a debate on how the permeability transition pore, a...
Excessive lung release of neutrophil DNA traps may explain severe complications in COVID-19 patients
- ScienceDaily
- 20/9/14 17:41
Researchers have detected significant amounts of DNA traps in distinct compartments of the lungs of patients who died from Covid-19. These traps, called NETs, are released massively into the airways, the lung tissue and the blood vessels. Such excessive release could be a major contributor to severe disease complications leading to in-hospital death.
New X-ray microscopy technique enables comprehensive imaging of dense neural circuits
- ScienceDaily
- 20/9/14 17:41
A new x-ray microscopy technique could help accelerate efforts to map neural circuits and ultimately the brain itself. Combined with artificial intelligence-driven image analysis, researchers used XNH to reconstruct dense neural circuits in 3D, comprehensively cataloging neurons and even tracing individual neurons from muscles to the central nervous system in fruit flies.

Climate change triggers migration, particularly in middle-income countries
- ScienceDaily
- 20/9/14 17:22
Environmental hazards affect populations worldwide and can drive migration under specific conditions. Changes in temperature levels, increased rainfall variability, and rapid-onset disasters, such as tropical storms, are important factors as shown by a new study. Environmental migration is most pronounced in middle-income and agricultural countries but weaker in low-income countries, where...
