Some Arctic regions regain their “greenness” within a decade of a sudden permafrost collapse, while others can take a century or more to recover, researchers report.

Scientists at Oregon Health & Science University have uncovered a previously unknown system of internal “trade winds” that help cells rapidly move essential proteins to the front of the cell, reshaping how researchers understand cell migration, cancer spread and wound healing.

The discovery, published today in Nature Communications, reshapes what researchers thought they knew about how cells direct proteins to the right place at the right time.

A new squeezed phonon laser developed by researchers at the University of Rochester and Rochester Institute of Technology provides precise control over phonons at the nanoscale level. This could give new insights into the nature of gravity, particle acceleration, and quantum physics.

In a recent paper published in Scientific Reports, a UW-led team documented new habits and habitats for Nautilus and Allonautilus species. 

The breakthrough enables larger capacities for quantum information using complex states of light that are less affected by imperfections, paving the way for potential innovations in medicine, materials science, data management and security.

A research team led by Purdue University’s W. Andy Tao has discovered of a new type of protein modification related to cellular mutation that impairs a crucial enzyme’s ability to help drive energy processes. Their discovery, reported in Nature Chemistry, opens a new route to therapeutic cancer intervention.

Diversification and specialization are central to complex adaptive systems, yet overarching principles across domains remain elusive. Vicky Chuqiao Yang, assistant professor at the MIT Sloan School of Management, and James Holehouse, a mathematical biologist with the Santa Fe Institute led a research project that has  introduced a general theory that unifies diversity and specialization across disparate systems, including microbes, federal agencies, companies, universities, and cities, characterized by two key parameters. The research team show from extensive data that function diversity scales with system size as a sublinear power law-resembling Heaps’ law-in all but cities, where it is logarithmic. Their theory explains both behaviors and suggests that function creation depends on system goals and structure: federal agencies tend to ensure functional coverage; cities slow new function growth as old ones expand; and cells occupy an intermediate position. Once functions are introduced, their growth follows a remarkably universal pattern across all systems.
