Phys.org / Engineers find a precise way to grow artificial blood vessels
Tissue engineers are finding ways to grow living organs and tissues from cells, with the aim of replacing diseased and damaged counterparts in the body. Scientists have successfully grown artificial muscles, livers, kidneys, ...
Phys.org / Study reveals Hawaiian hotspot is getting hotter
Contrary to conventional geological thinking, the Hawaiian mantle plume has gotten hotter by about 250°C (480°F) over the past 47 million years. This discovery, led by Earth scientists at the University of Hawai'i at Mānoa, ...
Dialog / Ocean acidification emerging as a planetary signal linking today's carbon emissions to Earth's deep-time memory
When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those concerns are real. But while working on our recent research, I found myself asking a different question: ...
Phys.org / Data-driven tool can find mineral biosignatures on other worlds
A technique for judging whether a common mineral formed through biological activity could aid the search for ancient life on Earth and Mars. Apatite is a ubiquitous phosphate mineral found in terrestrial and extraterrestrial ...
Phys.org / Haven or trap? Study finds sinkholes protect endangered tree at evolutionary cost
Are giant sinkholes in China's karst mountains havens or traps for the rare plants that inhabit them? A new study finds they are both—offering refuge from heat and drought while gradually eroding the evolutionary potential ...
Phys.org / Heavy-element exotic dust may solve a neutron star merger mystery
When neutron stars merge, they create a powerful explosion called a kilonova that flings out neutron-rich material, some of which decays into heavy elements through a process called the r-process. Recent observations of kilonovae ...
Phys.org / Statistical test helps judge the value of personalization
From precision medicine to personalized job training, customizing interventions for individuals is often assumed to produce better outcomes than a one-size-fits-all approach. But personalization also comes with costs: it ...
Phys.org / Six years of drought reshape soil microbiomes in tallgrass prairie, study finds
A new study tracking soil microbial communities across six years of experimental drought in a tallgrass prairie finds that prolonged water stress diminishes biodiversity, pushing communities toward less predictable, harder-to-reverse ...
Phys.org / How tides and river water combine to amplify floods
Ocean tides push upstream along coastal rivers, in some cases reaching hundreds of kilometers (hundreds of miles) inland. These inland stretches are known as tidal rivers, and they're the scene of complex interactions between ...
Phys.org / Space cargo costs could fall more than 90% by 2040, study suggests
The expense of launching cargo into space will plummet over the next few years, with the cost of reaching orbit forecast to more than halve between now and the end of the decade, and fall by around 93% by 2040, according ...
Phys.org / Twisted ultrathin magnet retains magnetization after field changes, study finds
The properties of ultrathin magnets can be specifically altered by a slight twist between two atomic monolayers. This is the conclusion reached by an international research team led by TU Darmstadt in a study published in ...
Phys.org / Disturbance has a greater effect on giant kelp productivity than resource availability
Marine scientists at UC Santa Barbara have found that disturbances to giant kelp forests have a major influence on their net primary productivity (NPP)—an indicator of an ecosystem's health and its ability to support its ...
