A new study published in The Open Construction & Building Technology Journal by Dr. Carlos Alejandro Diaz Schery of the Department of Industrial Engineering, Pontifical Catholic University of Rio de Janeiro, Gávea, Rio de Janeiro, Brazil — together with co-authors Flávia de Souza Costa Neves Cavazotte and Rodrigo Goyannes Gusmão Caiado — makes a pointed observation about why so many Building Information Modelling (BIM) projects fall short of expectations: the problem lies less in the software and more about how organizations are led through the change. Despite over 120,000 published studies on BIM deployment, experts estimate that between 60 and 70 percent of BIM efforts fail to deliver the benefits that were expected. Schery et al.’s study argues that the missing piece is a clear understanding of which leadership behaviors are needed at each stage of an organization’s BIM journey — and that this gap is particularly consequential in Latin America, where cultural dynamics, resource constraints, and uneven institutional support make the challenge more complex than in Europe or North America.

For decades, scientists have searched for a clear link between the Sun’s explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see sharp changes in the weather — such as declines in precipitation — and the more powerful the storm, the more dramatic the shift.

The University of Hong Kong (HKU) has solidified its position in the highest echelons of global higher education, securing the 11th spot globally for the second year running in the QS World University Rankings 2027, announced by the global higher education analytics organisation Quacquarelli Symonds (QS) on 18 June. By retaining this historic high, HKU firmly cements its standing as a premier institution both globally and locally, leading the city’s higher education sector as a beacon of academic excellence and global impact.

Astronomers have followed a faint, cosmic trail of gas to a third galaxy that has no dark matter. 

In a new study in The Astrophysical Journal, a team of Yale astronomers reports on a dwarf galaxy located45 million light-years from Earth — called NGC 1052-DF9 — that appears to have formed in a straight line with nine other galaxies. 

Two of those other galaxies, DF2 and DF4, were previously shown to lack dark matter — an invisible, theorized material that gives shape to the universe and is thought by most astronomers to be essential to galaxy formation. 

Now, DF9 has joined the no-dark-matter club. 

“A line of galaxies lacking dark matter has never been seen before,” said Michael Keim, a Ph.D. student in astrophysics in Yale’s Graduate School of Arts and Sciences and first author of the new study. “The discoveryprovides some of the strongest evidence yet that these galaxies formed through an extreme and previously unseen process and offers a rare new window into the nature of dark matter itself.” 

Keim’s advisor, Yale astronomer Pieter van Dokkum, led the original studies that analyzed DF2 and DF4, using data from the Hubble Space Telescope. Van Dokkum, the Sol Goldman Family Professor of Astronomy and professor of physics in Yale’s Faculty of Arts and Sciences, is co-author of the new study. 

A study conducted by UC Santa Barbara researchers and collaborators has found that California has lost more than half of its coastal dune systems. The researchers’ assessment — the first of its kind for the California coast — estimates that 60% of dune systems that existed from 1850, due to a combination of urban development, land-use changes and erosion.
