Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a "double shot" at life and reduce waste going to landfills. [...]
Published in the Journal of Cleaner Production, the study by RMIT engineers is the first to prove that waste coffee grounds can be used to improve concrete.
— Science Daily
The study found that three different coffee ground samples each increased their concrete pour’s compressive strengths by up to 30% once their organic compounds were broken down through pyrolysis. The discovery could go a long way in combatting issues such as food waste and the carbon impact of... View full entry
Retrofitting the UK’s historical buildings, from Georgian townhouses to the mills and factories that kickstarted the Industrial Revolution, could generate £35bn of economic output a year, create jobs and play a crucial role in achieving climate targets, research has found.
The organisations behind the report are calling on the government to work with industry to [...] advice into a national retrofit strategy, as the UK only has half the skilled workers needed to retrofit all old buildings.
— The Guardian
The report from a consortium that includes the National Trust, Historic England, and property group Grosvenor also outlined Britain’s need for 105,000 additional skilled workers to help meet the country’s lagging 2050 net zero decarbonization goals. By that time, the retrofitting market is... View full entry
The abundance of feral pigeons [...] is mostly affected by the presence of modern buildings with low abundance of pigeons found in areas where there is a preponderance of modern buildings.
The study confirms the results of international studies which indicate that the densest populations of feral pigeons occur in historic town centres, as the old buildings provide ample nesting sites, while the high human population density of both locals and tourists in historic towns provides constant food

According to the authors, the Maltese study “lays the ground for further research on feral pigeon populations and their ecology in urban environments as well as contributing information for management programmes that are tailor-made to the local situation and circumstances.” Rat populations...

A new study published in Accident Analysis & Prevention shows how biometric data can be used to find potentially challenging and dangerous areas of urban infrastructure before a crash occurs. Lead author Megan Ryerson led a team of researchers in the Stuart Weitzman School of Design and the School of Engineering and Applied Science in collecting and analyzing eye-tracking data from cyclists navigating Philadelphia’s streets. — Penn Today
As explained in a piece by Penn Today, current federal rules for making safe transportation interventions require the notation of crashes. This reactive approach relies on previous human cost before new considerations are made. Seeking to minimize harmful events altogether, Ryerson and her team... View full entry

Boston continues to hold the dubious distinction of having the worst traffic in the United States, fending off the likes of Los Angeles, New York and Chicago to top traffic data analyst INRIX’s list of congested cities for the second year in a row. [...]
Chicago, Philadelphia, New York and Washington, D.C., round out the worst five U.S. cities for congestion. Wichita, Kansas, tops the study for least congestion.
— Boston Herald
The latest annual Global Traffic Scorecard published by transportation analytics company INRIX calculated that the average Boston commuter lost 149 hours — that's more than six days — per year due to traffic congestion, amounting to $2,205 per driver in time lost. Boston ranked as the... View full entry
Perhaps it’s not a surprise in a city where residential prices can reach into the stratosphere, but in Los Angeles, more than 17 percent of all homes are valued at over $1 million.
What may be more shocking is that L.A. doesn’t have the highest share of million-dollar homes. [...]
San Jose and San Francisco were No. 1 and No. 2, respectively. In San Jose, homes valued over $1 million made up 53 percent of the market. San Francisco’s million-dollar-share was at 40 percent.

Other major cities ranked in the new LendingTree survey are New York (4th place with 12 percent market share), Miami (9th, 4 percent), and Chicago (18th, 1.3 percent). View full entry

The Los Angeles region once again topped the list of areas with the worst traffic congestion for the sixth year in a row, according to a report by INRIX, a company that specializes in car services and transportation analytics.
Drivers in and around Los Angeles spent 102 hours battling traffic congestion during peak hours in 2017, INRIX's said. By contrast, New York City motorists spent 91 hours battling peak-hour congestion. New York was No. 3 on the INRIX list. No. 2 was Moscow.

Researchers from the Urban Displacement project, a joint UCLA and UC Berkeley effort, recently released a gentrification map of Los Angeles.
They examined the city from 1990 to 2000 and up to 2015, focusing on neighborhoods near transit stops. The goal was to see if these areas saw higher rents and more displacement than other areas.
The answer? Yes — with some exceptions.

Some of the UCLA researchers' key findings for Los Angeles Country (via the project's website, urbandisplacement.org):Our analysis found that areas around transit stations are changing and that many of the changes are in direction of neighborhood upscaling and gentrification.Examining the changes...
