This groundbreaking biomaterial heals tissues from the inside out
<div>A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.</div>
Ask HN: Nice Enrichments of Turing Machines?
Turning equivalence makes me feel less inspired about computing ideas. I think I lack enough knowledge to know what is left that is interesting.Are there good examples of machines which are technically Turing equivalent but bring certain unique phenomena into reach?An example of me not really seeing fruitfulness:Suppose I were to make a variant of a turning tape machine that could store irrational numbers instead of just ones or zeros.Would it bring any interesting programs within reach that wou

Researchers work to reduce the amount of precious metals in catalytic converters
The precious metals, such as platinum, palladium and rhodium, in catalytic converters make the vehicle devices attractive to thieves, but researchers are working to reduce the amount of precious metals needed in them -- down to single atoms -- while still maximizing their effectiveness. In recent studies researchers showed that they could, respectively, use atomic platinum to control pollutants and operate the system at lower temperatures, which is crucial to removing harmful chemicals when a ve
A fairy-like robot flies by the power of wind and light
<div>The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?</div>
A neuro-chip to manage brain disorders
<div>Researchers have combined low-power chip design, machine learning algorithms, and soft implantable electrodes to produce a neural interface that can identify and suppress symptoms of various neurological disorders.</div>
Want a stronger biodegradable plastic? Add a 'pinch' of cream of tartar
<div>Cooking a delicious risotto and making plastics are actually very similar processes. In both, ingredients come together and are heated to create a product, but current recipes for synthesizing bioplastics often fall flat, producing flimsy materials. So, taking a hint from chefs, researchers now report on a way to 'season' biodegradable plastics to make them stronger. It just takes a 'pinch' of cream of tartar (tartaric acid) or citric acid.</div>
Under pressure: Breakthrough new material solves problem of wearable sensors
<div>Researchers have synthesized a new material that solves one of the most difficult problems in the quest to create wearable, unobtrusive sensitive sensors: the problem of pressure.</div>
Researchers can 'see' crystals perform their dance moves
<div>Researchers already knew the atoms in perovskites react favorably to light. Now they've seen precisely how the atoms move when the 2D materials are excited with light. Their study details the first direct measurement of structural dynamics under light-induced excitation in 2D perovskites.</div>
Will machine learning help us find extraterrestrial life?
<div>Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of interest.</div>
Powering wearable technology with MXene textile supercapacitor 'patch'
<div>Researchers are one step closer to making wearable textile technology a reality. Materials scientists have reported a new design of a flexible wearable supercapacitor patch. It uses MXene to create a textile-based supercapacitor that can charge in minutes and power an Arduino microcontroller temperature sensor and radio communication of data for almost two hours.</div>
Researchers demonstrate non-invasive method for assessing burn injuries
<div>Researchers combine a hand-held scanner with a neural network based on terahertz spectroscopy that can predict burn healing with 93% accuracy. The research has the potential to significantly improve burn healing outcomes by guiding surgical treatment plans.</div>
New ‘Mega Ranch’ Will Grow 45 Million Pounds of Mushroom Root for Plant-Based Meat
Last July, New York-based startup MyForest foods announced the opening of a vertical farm that would grow three million pounds of mycelium a year, all for plant-based bacon. Now competitor Meati Foods is blowing them out of the water with a facility that will be able to produce more than 45 million pounds of product once it’s fully scaled up. The company announced the opening of a factory it’s calling “Mega Ranch” in Thornton, Colorado (a suburb north of Denver) last week.
