Learn why the mitotic spindle, the key cellular "machine" for separating chromosomes, can withstand large forces. A team from UC San Francisco in Current Biology describes how fibers under load quickly renew and further strengthen. In an experiment with a microneedle in living cells, self-repair was recorded that helps DNA divide precisely into two cells.
Find out how CMS physicists at CERN's LHC, along with a team from MIT, observed in lead-ion collisions that quarks leave a “wake” in quark-gluon plasma. Using the Z boson as a neutral tag, they showed that this primordial medium of the early universe behaves like a thick liquid rather than a random scattering of particles.
Here’s what ARPA-H’s $25.8 million support for UC San Diego means: Prof. Shaochen Chen’s team, under the PRINT program, aims to use 3D bioprinting, AI vascular design, and iPSC cells to create a patient-compatible liver and reduce waiting lists, the need for donors, and lifelong immunosuppression in the U.S.
Learn how Hurricane Melissa, before its devastating strike on Jamaica, lifted sediment from Pedro Bank and tinted the Caribbean Sea Maya blue. NASA Earth Observatory explains what Terra/MODIS reveals about currents, the ecosystem, and the carbon cycle.
Find out what the new MIT Energy Initiative study, published in Energy & Environmental Science, brings: the largest global database compares the cost and emissions of ammonia supply chains in 63 countries, including logistics and trade routes, and clarifies the trade-off between blue and green ammonia.
Learn how the Copernicus Sentinel-1 mission, over a decade of continuous radar measurements, reshaped our understanding of ice motion in Greenland and Antarctica, why glacier speeds are crucial for projecting global sea-level rise, and how new satellites and ROSE-L expand monitoring capabilities.
