Applying shockwaves can improve conditions for fluid mixing in supersonic combustion engines, paving the way for flights at speeds five times faster than the speed of sound.
Working from home has become part of the so-called "new normal" for many people during the COVID-19 pandemic. However, there has been a move underway towards increased telecommuting for many years. Writing in the Global Business and Economics Review a research team from Portugal has set out to explore the potential of telecommuting in terms of productivity and quality of life gains, cost savings...
The COVID-19 pandemic has made it especially challenging for marine scientists to make observations and carry out experiments at sea. Research cruises have been cut back or canceled because it is difficult to keep a safe distance between scientists and crew in the tight spaces on a research vessel. In this current situation, MBARI's robotic vehicles and instruments have proven to be very useful.
A global meta-analysis led by UNSW scientists shows tiny organisms that cover desert soils—so-called biocrusts—are critically important for supporting the world's shrinking water supplies.
Mimicking the structure of the kidney, a team of scientists from Lawrence Livermore National Laboratory (LLNL) and the University of Illinois at Chicago (UIC) have created a three-dimensional nanometer (nm)-thin membrane that breaks the permeance-selectivity trade-off of artificial membranes.
Economies across the world are on course to face the worst fall in GDP figures since 2008. In the UK, GDP fell by 10.4% in the first three months of 2020, and a whopping 20.4% in the month of April, the largest fall since records began in 1997. The Bank of England predicts that GDP will fall by 14% this year, probably more. The IMF has revised downward its forecast for global economic growth from...
Conservation projects in cities are most likely to succeed when nearby residents are part of the planning and design process and feel ownership over the projects, researchers who spent seven years studying conservation in Cleveland say.

New, peer-reviewed research published today by the Social Analytics Lab at the MIT Initiative on the Digital Economy in the prestigious Proceedings of the National Academy of Sciences shows the devastating cost of the current chaotic and uncoordinated reopening of states and cities across the US. The study, which used data from mobile phones, network connections through social media and census...
This video shows Jezero crater, the landing site of the NASA Mars 2020 Perseverance rover on the Red Planet, based on images from ESA's Mars Express mission. The planned landing area is marked with an orange ellipse.
We are changing the Earth system at a unprecedented speed without knowing the consequences in detail. Increasingly detailed, physics-based models are improving steadily, but an in-depth understanding of persisting uncertainties is still lacking. The two main challenges have been to obtain the necessary amount of detail in the models and to accurately predict how anthropogenic carbon dioxide...
Had Britain devised clear, tough outbreak control measures, the latest Covid-19 restrictions wouldn’t have been necessaryCoronavirus – latest updatesSee all our coronavirus coverageMore than 4 million people in the north of England woke up on Friday morning to the news that coronavirus restrictions were being reimposed. This follows the local lockdown in Leicester. Such measures are entirely...

T lymphocyte cells develop in the thymus. They are essential for fighting infections and preventing cancer. The thymus is located just above the heart. It is large in children and gradually reduces in size with age. In the thymus, T lymphocytes develop from progenitor cells, which originate in the bone marrow and travel to the thymus through the bloodstream. This is a continuous process in which...
The primary cause of climate change is atmospheric CO2, and levels are rising every day. There is, therefore, a great need to find ways to reduce CO2 levels. On other hand, an excessive amount of plastic waste has become a serious environmental problem. In this work, published in Nature Communications, researchers dealt with both problems at one stroke, by developing nano solid acids that...
As global warming continues to escalate, there are lasting implications to consider, including the changes to biological communities in vital habitats such as coral reefs. A team of researchers, led by Simon Brandl (currently at the Center de Recherches Insulaires et Observatoire de l'Environnement, CRIOBE, France) and Jacob Johansen, an assistant research professor at Hawai'i Institute of Marine...
A team of scientists led by UK Met Office has achieved a scientific breakthrough allowing the longer-term prediction of North Atlantic pressure patterns, the key driving force behind winter weather in Europe and eastern North America. CMCC scientists Panos Athanasiadis, Alessio Bellucci, Dario Nicolì and Paolo Ruggieri from CSP—Climate Simulation and Prediction Division were also involved in...
Much of western Europe was sweltering in a heatwave on Friday, but visitors to one Belgian safari park could at least seek shelter in an igloo with a cool view.

Earth. A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like Jupiter.
In March of 2015, protests broke out at the University of Cape Town in South Africa over the campus statue of British colonialist Cecil Rhodes. Rhodes, a mining magnate who had gifted the land on which the university was built, had committed genocide against Africans and laid the foundations for apartheid. Under the rallying banner of “Rhodes Must Fall,” students demanded that the statue be...
Nasa has successfully launched its next-generation Perseverance rover on a seven-month journey to Mars in search of evidence of ancient microbial life on the red planet. The car-sized robot will attempt to land on the Jezero crater – which may have been a lake more than 3.5bn years ago – where it will gather information about Mars’s geology, atmosphere and environmental...
