Sugar permeation discovered in plant aquaporins      (via sciencedaily.com)     Original source 

Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.

A farsighted approach to tackle nearsightedness      (via sciencedaily.com)     Original source 

As humans age, our eyes adjust based on how we use them, growing or shortening to focus where needed, and we now know that blurred input to the eye while the eye is growing causes myopia. It is so specific that the eye grows exactly to compensate for the amount and the direction of blur. Researchers have built a high-frequency ultrasonography system to measure eye size and how quickly eyes grow to better understand myopia and its contributing factors.

Wildfires have erased two decades' worth of air quality gains in western United States      (via sciencedaily.com)     Original source 

A new study concludes that wildfires originating in the western United States and Canada have erased air quality gains over the past two decades and caused an increase of premature deaths in fire-prone areas and downwind regions, primarily in the western U.S.

New implants linked to less infection and better recovery from orthopedic surgery      (via sciencedaily.com)     Original source 

Superior knee and hip replacements are a step closer after researchers further test and develop a new orthopedic implant coating which has the strong ability to ward off infection -- as well as stimulate bone growth.   The technology consists of novel Silver-Gallium (Ag-Ga) nano-amalgamated particles that can be easily applied to medical device surfaces.

Recycling concrete using carbon can reduce emissions and waste      (via sciencedaily.com)     Original source 

Amid the rubble of large-sale earthquake, war or other disaster -- and as ageing buildings and infrastructure are replaced -- mountains of concrete are often taken to landfill or pounded into rubble for roads. For a more sustainable approach, experts are developing a 'value add' for old broken concrete to 'upcycling' coarse aggregate to produce a strong, durable and workable concrete using a small amount of a secret ingredient -- graphene.

Boiled bubbles jump to carry more heat      (via sciencedaily.com)     Original source 

The topic of water and the way it can move producing water droplets that leap -- propelled by surface tension -- and frost that jumps -- by way of electrostatics -- is a central focus of a group of scientists. Having incorporated the two phases of liquid and solid in the first two volumes of their research, their third volume investigates a third phase, with boiling water.

1.5°C pathways can still be achieved, combining fairness and global climate protection      (via sciencedaily.com)     Original source 

Global warming can still be limited to 1.5°C by 2100 while ensuring that the poor are not hit hardest by climate policies and climate impacts. This is achieved by immediately introducing broad carbon pricing together with re-distributive policies using carbon pricing revenues and further measures to reduce energy consumption, accelerate technological transitions, and transform the land sector.

Needle-free ultrasound vaccine delivery      (via sciencedaily.com)     Original source 

Researchers are investigating the potential of a painless, needle-free vaccine delivery by ultrasound. The method uses cavitation, which is the formation and popping of bubbles in response to a sound wave. Though initial in vivo tests reported 700 times fewer vaccine molecules were delivered by the cavitation approach compared to conventional injection, the cavitation approach produced a higher immune response. The researchers theorize this could be due to the immune-rich skin the ultrasonic delivery targets. The result is a more efficient vaccine that could help reduce costs and increase efficacy.

Teaching physics from the din of flying discs      (via sciencedaily.com)     Original source 

The sound a disc makes while soaring through the air is full of information about how fast the disc is flying and how quickly it spins. This inspired Kyle S. Dalton of Penn State University to combine disc golf and acoustics into an interactive acoustic signal processing lesson. He set three microphones in a line and connected them to equipment that converts each microphone's signal to a data point. Then he threw a disc with a small whistle mounted on top and recorded the flying disc's acoustical signal. The resulting dataset can be used to learn basic processing tools and practice data visualization.

Tracking undetectable space junk      (via sciencedaily.com)     Original source 

Satellite and spacecraft operators may finally be able to detect small pieces of debris orbiting Earth using a new approach. Colliding pieces of space debris emit electric signals that could help track small debris littering Earth's orbit, potentially saving satellites and spacecraft.
