Nanocarrier delivery has huge potential in agriculture; however, there are significant scientific and societal barriers to overcome. In this Review, the authors explore the state of the field, what lessons can be learned from nanomedicine, and discuss what scientific and societal issues need to be addressed.
(Nanowerk News) Advanced technologies enable the controlled release of medicine to specific cells in the body. Scientists argue these same technologies must be applied to agriculture if growers are to meet increasing global food demands.
In a new Nature Nanotechnology journal review paper (“Towards realizing nano-enabled precision delivery in plants”), scientists from UC Riverside and Carnegie Mellon University highlight some of the best-known strategies for improving agriculture with nanotechnology.
The neurotransmitter dopamine has often been linked to pleasure-seeking behaviors and making stimuli paired with rewards (e.g., food, drinks) valuable. Nonetheless, the processes through which this key chemical messenger contributes to learning have not yet been fully elucidated.
Space lovers have an opportunity to watch two unique occurrences at the International Space Station this week, but you will have to stay up pretty late — or wake up very early — to see them live.
According to NASA, the cargo spacecraft carrying three tons of food, fuel and supplies to the ISS is for the Expedition 71 crew.
The unpiloted spacecraft – called Progress 88 – is scheduled to launch on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan on Thursday at 2:43 p.m. local time.
It’s a Saturday afternoon at a kids’ birthday party. Hordes of children are swarming between the spread of birthday treats and party games. Half-eaten cupcakes, biscuits and lollies litter the floor, and the kids seem to have gained superhuman speed and bounce-off-the-wall energy.
But is sugar to blame?
The belief that eating sugary foods and drinks leads to hyperactivity has steadfastly persisted for decades. And parents have curtailed their children’s intake accordingly.
Our guest in this episode is Dr. Mark Kotter. Mark is a neurosurgeon, stem cell biologist, and founder or co-founder of three biotech start-up companies that have collectively raised hundreds of millions of pounds: bit.bio, clock.bio, and Meatable.
In addition, Mark still conducts neurosurgeries on patients weekly at the University of Cambridge.
Lowtek Games combined the multifunctionality of a screen with the beauty of a pop-up book in a unique project that will take your imagination to another level. Codenamed Lowtek Lightbook, this interactive experience allows you to not only read stories but also play various games.
For example, you can color pictures with digital paints, find hidden objects, run away from aliens, or deliver food to them – all thanks to projection mapping and Lowtek Games’ clever thinking. Moreover, the story of Bib Goes Home can be even more engaging if you manually make Bib go home and explore his surroundings using a controller and a projector.
Users simply register by taking a selfie and then verify their identity and payment transaction by looking at the restaurant’s camera, according to CNBC.
In essence, it acts very similar to Apple’s Face ID.
The Cali-based software company explained the tech on its website, reading: ‘PopID is the universal gateway for verifying an individual’s identity based on their face for applications such as loyalty and payment.’
Dead stars known as white dwarfs, have a mass like the sun while being similar in size to Earth. They are common in our galaxy, as 97% of stars are white dwarfs. As stars reach the end of their lives, their cores collapse into the dense ball of a white dwarf, making our galaxy seem like an ethereal graveyard.
Despite their prevalence, the chemical makeup of these stellar remnants has been a conundrum for astronomers for years. The presence of heavy metal elements—like silicon, magnesium, and calcium—on the surface of many of these compact objects is a perplexing discovery that defies our expectations of stellar behavior.
“We know that if these heavy metals are present on the surface of the white dwarf, the white dwarf is dense enough that these heavy metals should very quickly sink toward the core,” explains JILA graduate student Tatsuya Akiba. “So, you shouldn’t see any metals on the surface of a white dwarf unless the white dwarf is actively eating something.”
Imagine a technology that could genetically rewire organisms in real-time, silencing critical genes across entire ecosystems with unknown effects.
