Cooperation under pressure: Lessons from the COVID-19 swab crisis
A major crisis that accompanied the rise of the pandemic was lack of availability of the nasopharyngeal swab — necessary for testing for COVID-19, which in turn, was necessary to get a grip on the pandemic. An account of how one group addressed that c…
Developing enhanced fish vaccines with nanocellulose
Scientists are developing new fish vaccines using nanocellulose produced from Maine’s wood pulp industry. Nanocellulose poses no known harmful effects to fish tissue and is unlikely to cause cellular damage. Fish vaccines made with nanocellulose may al…
Mystery of the seadragon solved
The genome of the seadragon, a very unusual fish, has been decoded. Seadragons (Phyllopetryx taeniolatus) live off the coast in western and southern Australia. Evolutionary biologists have now found the genetic basis for some external characteristics o…
The case for onboard carbon dioxide capture on long-range vehicles
A research team offers a practical way to make ships CO2 neutral — or even CO2 negative — with CO2-capturing solid oxide fuel cells. After ‘burning’ traditional carbon-based fuels, the fuel cell generates concentrated CO2 that can be stored on-board …
Scientists growing more complex and mature heart tissue in the lab
A team led by researchers has generated premature cells that support early heart development but vanish soon after birth.
The fewer forests, the more space giant anteaters need, study finds
Giant anteaters living in less forested habitats make use of larger home ranges, according to a new study. This behavior may allow them to incorporate forest patches into their territory, the authors say.
What if our history was written in our grammar?
Humans have been always on the move, creating a complex history of languages and cultural traditions dispersed over the globe. An international team has now traced families of related languages over more than 10,000 years by combining data from genetic…
‘Shadow waveguide’ casts complex acoustic patterns to control particles
Engineers have devised a new approach to using sound waves to conduct complex manipulations of tiny particles suspended in liquid. Dubbed a ‘shadow waveguide,’ the technique uses only two sound sources to create a tightly confined, spatially complex ac…
Key mechanisms behind synapse degeneration in Alzheimer’s brain discovered
Neurobiologists have uncovered the long-sought-after mechanisms behind the maintenance and decline of key synapses implicated in brain disorders such as Alzheimer’s disease. The researchers identified the main components driving amyloid beta-associated…
Researchers bioprint an entire active glioblastoma tumor using a 3D printer
The 3D print of glioblastoma — the deadliest type of brain cancer — is printed from human glioblastoma tissues containing all components of the malignant tumor. Researchers say the breakthrough will enable much faster prediction of best treatments fo…
Magnets could offer better control of prosthetic limbs
Researchers have developed a new strategy that could offer much more precise control of prosthetic limbs. After inserting small magnetic beads into muscle tissue, they can accurately measure the length of a muscle as it contracts, and this measurement …
Emberometer could gauge threat of wildfire-spreading embers
As wildfire fronts advance through landscapes or communities on the ground, they also attack from above, launching volleys of glowing embers into the air. Also known as firebrands, these specks of burning debris can glide for up to 40 kilometers (appro…
Package delivery robots’ environmental impacts: Automation matters less than vehicle type
Whether a robot or a person delivers your package, the carbon footprint would essentially be the same, according to a new study that could help inform the future of automated delivery as the pandemic fuels a dramatic rise in online shopping.
Transformation in the particle zoo
An international study has found evidence of a long-sought effect in accelerator data. The so-called ‘triangle singularity’ describes how particles can change their identities by exchanging quarks, thereby mimicking a new particle. The mechanism also p…
