New algorithm aces university math course questions
Posted by Saúl Morales Rodriguéz in categories: education, information science, mathematics, robotics/AI
Multivariable calculus, differential equations, linear algebra—topics that many MIT students can ace without breaking a sweat—have consistently stumped machine learning models. The best models have only been able to answer elementary or high school-level math questions, and they don’t always find the correct solutions.
Now, a multidisciplinary team of researchers from MIT and elsewhere, led by Iddo Drori, a lecturer in the MIT Department of Electrical Engineering and Computer Science (EECS), has used a neural network model to solve university-level math problems in a few seconds at a human level.
The model also automatically explains solutions and rapidly generates new problems in university math subjects. When the researchers showed these machine-generated questions to university students, the students were unable to tell whether the questions were generated by an algorithm or a human.

Machine-learning model monitors and adjusts 3D printing process to correct errors in real-time
Posted by Saúl Morales Rodriguéz in categories: 3D printing, robotics/AI
Scientists and engineers are constantly developing new materials with unique properties that can be used for 3D printing, but figuring out how to print with these materials can be a complex, costly conundrum.
Often, an expert operator must use manual trial-and-error—possibly making thousands of prints—to determine ideal parameters that consistently print a new material effectively. These parameters include printing speed and how much material the printer deposits.

Yale-developed technology restores cell, organ function in pigs after death
Posted by Omuterema Akhahenda in categories: bioengineering, biotech/medical, chemistry, ethics, life extension
Within minutes of the final heartbeat, a cascade of biochemical events triggered by a lack of blood flow, oxygen, and nutrients begins to destroy a body’s cells and organs. But a team of Yale scientists has found that massive and permanent cellular failure doesn’t have to happen so quickly.
The researchers stressed that additional studies are necessary to understand the apparently restored motor functions in the animals, and that rigorous ethical review from other scientists and bioethicists is required.
The experimental protocols for the latest study were approved by Yale’s Institutional Animal Care and Use Committee and guided by an external advisory and ethics committee.

Stroke drug improves memory and repairs injured brain tissue in mice
Posted by Raphael Ramos in categories: biotech/medical, neuroscience
Unlike existing treatments that focus on rehabilitation or reducing the risk of an additional stroke, the experimental drug targets the “stickiness” that can prevent injured brain tissue from functioning as it should.

Legitimate Cold Fusion Exists | Muon-Catalyzed Fusion
Posted by Jamie McGuigan in category: particle physics
Cold Fusion is possible by replacing Hydrogen Electrons with Muons.
- Takes 5GeV to create a Muon, they only live for 2.2 microseconds.
- Muons provide a catalyst for 150 fusion events, before sticking to Helium Atom.
- Net fusion output is 2.7GeV per 5GeV Muon.

Swiss team creates most efficient silicon-based solar cell ever
Posted by Quinn Sena in categories: solar power, sustainability
Swiss researchers have done the (theoretically) impossible, creating not one but two silicon-based solar cells with efficiencies greater than 30% — breaking a world record and potentially illuminating the path to a future of cheaper clean energy.
The status quo: Solar cells absorb light and convert it into electricity. They’re the basis of most solar power tech, and about 95% of them are made from silicon because it’s abundant, long-lasting, and relatively cheap.
Most of the silicon solar cells sold today are about 22% efficient, meaning they convert 22% of the solar energy that hits them into electricity. We don’t have too much room for improvement with silicon solar cells, either, as they have a theoretical efficiency limit of about 29%.
