3D Printing Paves Way for “Designer” Titanium Alloys

A collaborative research team has developed a new class of titanium alloys that are strong and ductile rather than brittle. The innovative design combines the use of alloy with 3D-printing processes, potentially revolutionizing applications in sectors like aerospace, biomedical, chemical engineering, space, and energy. These alloys comprise a blend of alpha-titanium and beta-titanium phases, with the added use of oxygen and iron as stabilizers and strengtheners. Researchers have developed a new class of ductile and strong titanium alloys using a combination of alloy design and 3D printing. The findings, published in Nature, could revolutionize applications in various sectors, including aerospace…

AI Battles Superbugs: Helps Find New Antibiotic Drug To Combat Drug-Resistant Infections

Lead Image: AI technology has helped MIT and McMaster University researchers identify a new antibiotic named abaucin, effective against Acinetobacter baumannii, a hospital-borne, drug-resistant bacteria. The drug, discovered through a machine-learning model, is significant due to its narrow-spectrum efficacy and unique mechanism of disrupting lipoprotein trafficking within bacterial cells. The machine-learning algorithm identified a compound that kills Acinetobacter baumannii, a bacterium that lurks in many hospital settings. Using an artificial intelligence algorithm, researchers at MIT and McMaster University have identified a new antibiotic that can kill a type of bacteria that is responsible for many drug-resistant infections. If developed for…

STING Like a Bee: MIT’s Revolutionary Approach to Cancer Immunotherapy

A cancer vaccine combining checkpoint blockade therapy and a STING-activating drug eliminates tumors and prevents recurrence in mice. MIT researchers have engineered a therapeutic cancer vaccine that targets the STING pathway, vital for immune response to cancer cells. This vaccine has shown significant potential in eliminating tumors, inhibiting metastasis, and preventing recurrence in mouse models of different cancers, with minimal side effects. The treatment is even effective in cases where the STING gene is mutated. The study also revealed an unexpected key role of CD4+ T cells in antitumor immunity. Immune checkpoint blockade therapies have been revolutionary in the treatment…

MIT’s AI System Reveals Internal Structure of Materials From Surface Observations

Lead Image: A machine-learning method developed at MIT detects internal structures, voids, and cracks inside a material, based on data about the material’s surface. On the top left cube, the missing fields are represented as a gray box. Researchers then leverage an AI model to fill in the blank (center). Then, the geometries of composite microstructures are identified based on the complete field maps using another AI model (bottom right).

MIT scientists have used…

Rare Beetle Rediscovered After 55 Years

Lead Image: UC Berkeley entomologist Kipling Will discovered a specimen of Bembidion brownorum while sampling for insects near Freshwater Creek on former Gov. Jerry Brown’s ranch. The species had not been observed by scientists in more than 55 years. Credit: David Maddison During the insect sampling expedition at Jerry Brown’s ranch, a researcher from UC Berkeley stumbled upon a beetle species that had eluded scientific observation since 1966. Upon learning that ex-Governor Jerry Brown was inviting field researchers to his Colusa County ranch, Kipling Will, a University of California, Berkeley entomologist, was eager to seize the opportunity to search for…
