Antarctica remains the wild card for sea-level rise estimates through 2100

by

A massive collaborative research project covered in the journal Nature this week offers projections to the year 2100 of future sea-level rise from all sources of land ice, offering the most complete projections created to date.

“This work synthesizes improvements over the last decade in climate models, ice sheet and glacier models, and estimates of future greenhouse gas emissions,” said Stephen Price, one of the Los Alamos scientists on the project.

“More than 85 researchers from various disciplines, including our team at Los Alamos National Laboratory, produced sea-level rise projections based on the most recent computer models developed within the scientific community and updated scenarios of future greenhouse gas emissions,” said Price.

    Melting ice sheets over the past 300 years raised sea levels 18 metresIt is well known that climate-induced sea level rise is a major threat. New research has found that previous ice loss events could have caused sea-level rise at rates of around 3.6 metres per century, offering vital clues as to what lies ahead should climate change continue unabated.

Researchers generate ‘the highest laser intensity ever reached’

by

Recently, laser scientists at the Center for Relativistic Laser Science (CoReLS) within the Institute for Basic Science (IBS) in South Korea realized the unprecedented laser intensity of 1023 W/cm2.

This has been a milestone that has been pursued for almost two decades by many laser institutes around the world.

An ultrahigh intensity laser is an important research tool in several fields of science, including those which explore novel physical phenomena occurring under extreme physical conditions. [Read more…] about Researchers generate ‘the highest laser intensity ever reached’

Partnerships between researchers, policymakers and practitioners improve early childhood education

by

Research-practice partnerships (RPPs), long-term collaborations between researchers, policy makers and practitioners, represent an especially promising strategy for making sure that all children benefit from early childhood education, according to a journal released today by Princeton University and the Brookings Institution.

The journal, Future of Children, edited by Daphna Bassok of the University of Virginia and Pamela Morris of New York University’s Steinhardt School, argues that RPPs are crucial for solving today’s most pressing question in early childhood education – how to deliver high-quality prekindergarten programs at scale.

“Too often there is a disconnect between the questions researchers tackle and the ones that are more urgent and salient for policy makers or practitioners,” said Bassok. “The findings from rigorous, well-designed research studies may not be particularly useful for addressing the real-life complexity that educators and policymakers face.” [Read more…] about Partnerships between researchers, policymakers and practitioners improve early childhood education

Election campaigns: Attacks and smearing backfire and can benefit other candidates

by

Candidates often give in to temptation to attack opponents in electoral campaigns through negative ads (more than 55% of the ads aired by the Clinton and Trump campaigns in 2016 were negative), even if evidence of this tactic effectiveness is, at least, mixed.

A study by Bocconi University professors Vincenzo Galasso, Tommaso Nannicini and Salvatore Nunnari, just published in the American Journal of Political Science, reveals the backlash of electoral smearing and shows that, in a three-candidate race, it’s the “idle candidate” (the one neither attacking nor being attacked) to have the upper hand.

During a three-candidate mayoral race in a mid-sized Italian town in 2015, the authors were able to randomize the door-to-door canvassing activity of volunteer supporters of one of the challengers to the incumbent mayor.

World’s first fiber-optic ultrasonic imaging probe for future nanoscale disease diagnostics

by

Scientists at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D.

The new technology produces microscopic and nanoscopic resolution images that will one day help clinicians to examine cells inhabiting hard-to-reach parts of the body, such as the gastrointestinal tract, and offer more effective diagnoses for diseases ranging from gastric cancer to bacterial meningitis.

The high level of performance the technology delivers is currently only possible in state-of-the-art research labs with large, scientific instruments – whereas this compact system has the potential to bring it into clinical settings to improve patient care.

Revealing the secret cocoa pollinators

by

The importance of pollinators to ensure successful harvests and thus global food security is widely acknowledged.

However, the specific pollinators for even major crops – such as cocoa – haven’t yet been identified and there remain many questions about sustainability, conservation and plantation management to enhance their populations and, thereby, pollination services.

Now an international research team based in Central Sulawesi, Indonesia and led by the University of Göttingen has found that in fact ants and flies – but not ceratopogonid midges as was previously thought – appear to have a crucial role to play.

Climate change impacts conservation sites across the Americas

by

A continental-scale network of conservation sites is likely to remain effective under future climate change scenarios, despite a predicted shift in key species distributions.

New research, led by Durham University and published in the journal Frontiers in Ecology and Evolution, investigates the impacts of potential climate change scenarios on the network of Important Bird and Biodiversity Areas (IBAs) across the Caribbean, and Central and South America.

The research was carried out in collaboration with Senckenberg Biodiversity and Climate Research Centre, BirdLife International and the National Audubon Society. [Read more…] about Climate change impacts conservation sites across the Americas

Six out of every 10 teachers believe that changing the design of the classroom is key to improving learning

by

The image of rows of chairs and desks facing a teacher at a blackboard has been a reality for decades. However, research reveals that this way of organizing the classroom furniture in schools is not the best way for favouring the learning process.

Especially if the needs of 21st-century students are taken into account, who, according to the OECD, require a social environment that fosters autonomy, flexibility, decision-making capacity and the connection of knowledge by individual students or through teamwork.

It is also the opinion of 6 out of every 10 teachers that changing the design of the classroom is key to improving learning. [Read more…] about Six out of every 10 teachers believe that changing the design of the classroom is key to improving learning

Small generator captures heat given off by skin to power wearable devices

by

Scientists in China have developed a small, flexible device that can convert heat emitted from human skin to electrical power.

In their research, presented April 29 in the journal Cell Reports Physical Science, the team showed that the device could power an LED light in real time when worn on a wristband.

The findings suggest that body temperature could someday power wearable electronics such as fitness trackers. [Read more…] about Small generator captures heat given off by skin to power wearable devices

Dietary amino acid determines the fate of cancer cells

by

A research group at the RIKEN Center for Biosystems Dynamics Research (BDR) has discovered molecular events that determine whether cancer cells live or die.

With this knowledge, they found that reduced consumption of a specific protein building block prevents the growth of cells that become cancerous.

These findings were published in the scientific journal eLife and open up the possibility of dietary therapy for cancer. [Read more…] about Dietary amino acid determines the fate of cancer cells
