Synthetic proteins are being built with the help of AI models

Others are taking a slightly different tack. Profluent, in Emeryville, California and EvolutionaryScale, in New York, are building protein-design AI models that resemble not image-generating software, but large language models (LLMs) of the sort that power the world’s chatbots. These firms’ models treat the amino-acid sequences in protein chains like the words in a piece of text—analysing relationships found in zillions of exemplars to design novel useful structures. According to Ali Madani, Profluent’s chief executive, the firm is particularly focused on creating new CRISPR-Cas gene-editing tools. Here, its USP is a curated database of around 5m CRISPR-Cas protein complexes on which its AI model has been trained in order to design new versions. Read post

Aikium Wins Nebius AI Drug Discovery Award

Aikium targets “undruggable” proteins comprising half the human proteome using its Yotta-ML² platform. The company has secured partnerships with four organizations, including three top cancer hospitals, based on successful GPCR proof-of-concept work. Read post

Levitree: Lifting Cities out of Flood Danger with Robots

“San Rafael has the Bay Area’s largest flood problem,” Laurence Allen explains. “It’s a city of about 60,000 people facing a $500 to $900 million flood problem. When you run the math on that, the protection is just unaffordable.” Laurence hopes to help San Rafael and other coastal cities lift themselves out of flood danger using technology developed by Levitree, a Bakar Labs company of which he is COO. In short, Levitree uses robots to lift a property, and everything built on it, by injecting wood slurries deep beneath the surface, where it’s prevented from decomposing back into carbon dioxide. “Reshape the World” is their motto.

GigaCrop’s Chris Eiben wants to improve photosynthesis. Here’s how he’s doing it.

“The thing holding plants back today is the enzyme Rubisco,” Eiben says. “It’s the first enzyme a plant uses to take CO2 and start turning it into a sugar. But the enzyme is slow, and it has a tendency to use oxygen instead of CO2 . Which is incredibly costly for the plant to fix. I don’t have a clever way to make Rubisco better; land plants have been trying to improve it for 450 million years, which is a long time. Doing better than that is tough. So GigaCrop is inserting a parallel photosynthesis pathway into plants. “If a plant were an airplane, what we are doing is installing a more efficient engine. The trick is we have to do it while the airplane is flying. Plants must have a working engine at all times” he says. “Rubisco is part of a larger cycle called the Calvin-Benson cycle. Our pathway can exist next to the Calvin-Benson cycle, and they can both operate. But the plants will benefit because our pathway is faster and more energy efficient.” Read post

Cancer-fighting immune cells could soon be engineered inside our bodies

CAR T cells are among the most powerful therapies oncologists have to treat many types of blood cancer. And studies suggest that they might hold promise for brain cancer and other solid tumours, as well as autoimmune and other diseases. One research firm estimates that the value of the CAR-T-therapy market, expected to hit US$11 billion this year, will grow to nearly $190 billion by 2034. But CAR-T therapies come with a serious downside — they are laborious to make and difficult to administer. Some biotechnology companies have an answer: alter T cells inside the body instead…CRISPR–Cas9 pioneer and Nobel prizewinner Jennifer Doudna has co-founded a separate company, Azalea Therapeutics in Berkeley, California, that is developing in vivo CAR T.

Valitor Presents Multiple Preclinical Datasets on the Potential of its Innovative Anti-VEGF Therapy

“VLTR-559 was developed using our pioneering MVP technology platform and was designed to be an anti-VEGF therapy with increased potency and extended therapeutic duration compared to the current standard-of-care anti-VEGF biologics,” said Wesley Jackson, Ph.D., president and chief scientific officer of Valitor. “Based on our clinical modeling from preclinical results, we anticipate VLTR-559 could enable a twice-yearly dosing regimen for patients with wet AMD, thereby improving long-term outcomes while also reducing the clinical costs required to treat this disease. We are making great progress through IND-enabling activities with the goal of initiating a Phase 1 clinical study next year. Additionally, we are excited by the broader potential of our MVP platform, which is based on our proprietary methods of combining large molecular weight hyaluronic acid biopolymers with diverse active pharmaceutical ingredients to create potent and long-acting drugs.” Read post

Keylika Develops World’s First Buccal Patch for Iron Deficiency Anemia

“Most people have no idea how debilitating iron deficiency anemia can be. As a critical micronutrient, iron has a foundational role to play in multiple biological processes in the body down to the cellular level, its uncorrected deficiency has far-reaching consequences,” says Buddha Chaudhuri, Ph.D., CEO of Biotech company, Keylika. After years working on drug delivery and medical devices, Keylika’s team has pioneered what could be a breakthrough solution: the world’s first buccal (oral) patch for treating iron deficiency.
