Phys.org / Precise giants: New research reveals how blue whales find food in a vast ocean
Despite protections, blue whales remain endangered, primarily because of the risk of collisions with ships. MBARI's Blue Whale Observatory uses a suite of technologies to study these animals and their primary food source, ...
Tech Xplore / Metal foam front rails could make cars safer in collisions
A new study finds that composite metal foam (CMF) could significantly improve automobile safety during frontal collisions. Using computational models to run detailed simulations, researchers found that incorporating CMF into ...
Phys.org / Biodegradable 'nanobone' could one day help regrow bone without painful grafts
For children born with cleft lip and palate, repairing gaps in the jawbone often means waiting until they are 10 to 12 years old before undergoing invasive bone graft surgery. University of Sydney researchers have developed ...
Phys.org / Wrinkled or smooth? Cell growth mechanics determine shape of plant organs
When inner and outer cell layers of sepals—the leaf-like plant organs that cover and protect the flower bud before it opens—all grow upward, the organs stay smooth and uniformly stiff, which is optimal for the plant, according ...
Phys.org / Underwater meadows sustain millions in extreme poverty
A study provides the first large-scale empirical evidence that seagrass meadows act as a critical safety net for millions of coastal people living in extreme poverty across the Indo-Pacific.
Phys.org / Heavy water's atmospheric fingerprints boost weather forecasts for up to five days
Weather forecasts rely on many different kinds of data, including temperature, humidity and wind. For the first time, researchers, including those at the University of Tokyo, have demonstrated that a long-theorized improvement ...
Medical Xpress / Is poor sleep contributing to the country's weight issues?
Some 70% of teens trying to adapt to a fall schedule are missing out on sleep. Early bells and tough classes combine with delayed biological clocks during adolescence, keeping their nightly sleep duration during the school ...
Dialog / A Permian fossil may reveal the oldest known flowering-plant structure
Despite the importance and dominance of angiosperms ("flowering plants") in the current ecosystem, it is rather surprising that we know so little about their origin and early evolution. Paleobotanists have been making efforts ...
Medical Xpress / More frequent cannabis use linked to poorer mental health
More frequent cannabis use is associated with fewer days of good mental health among adults, particularly men, according to a study co-authored by a University of Miami Business School professor.
Phys.org / Surf's up: How the seafloor shapes breaking waves
A new study led by surfing scientists at the Scripps Institution of Oceanography at UC San Diego revealed the physical relationships underlying a pattern familiar to generations of surfers.
Phys.org / How stressed cells put the brakes on protein 'shipping'
Cells synthesize proteins in the endoplasmic reticulum (ER), and these proteins are transported to the Golgi apparatus for distribution to their ultimate destinations inside and outside the cell. The structures that transport ...
Medical Xpress / Microdroplets may reduce colorectal tumor growth at potentially lower cost
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth ...
