The Download: discovering proteins, and Pakistan’s climate crisis


This is today’s edition of Download, Our weekday newsletter provides daily coverage of what’s happening in the tech world.

An AI can design new proteins that could help unlock new cures and materials

What’s up?: A new AI tool can help researchers discover previously unknown proteins and design entirely new proteins. When harnessed, it could help unlock the development of more effective vaccines, speed up research into cancer cures, or lead to entirely new materials.

How it works: ProteinMPNN, developed by a team of researchers from the University of Washington, provides scientists with a tool that will complement the ability to predict the shape of all proteins known to science as a tool. DeepMind’s AlphaFold. ProteinMPNN will help researchers solve the inverse problem. If they had the correct protein structure in mind, it would help them figure out the amino acid sequence that folds into that shape.

Why is it important: Proteins are fundamental to life, and understanding their shape is essential to working with them. Traditionally, researchers design proteins by tweaking those that occur naturally, but ProteinMPNN opens up a whole new universe of possible proteins for researchers to design from scratch.

Climate change ‘fingerprint’ clear in devastating floods in Pakistan

What we know: Climate change is most likely to intensify the South Asian monsoon that has overwhelmed Pakistan in recent weeks, killing more than 1,000 people and destroying nearly 2 million homes. That’s according to a new analysis by World Weather Attribution, a network of scientists that uses climate models, weather observations and other tools to determine if global warming increases the likelihood of occurrence or severity of recent extreme weather events.

What we don’t know: Exactly how climate change’s role is unclear. Using climate models to pinpoint the role of global warming in amplifying the entire monsoon season has proved difficult, due to the combination of widespread variation in precipitation patterns. large periods of time, active natural processes that models may not fully capture and the changing weather of the territory. And the country’s weather could turn even more extreme. Read full story.

Two Sick Children and a $1.5 Million Bill: A Family’s Race for a Gene Therapy Cure

October 2018

Jennie and Gary Landsman launched an online appeal to save their son on Thanksgiving 2017. In a moving video, the couple describe how their two sons, Benny, 18 months, and Josh, four months – both have a fatal genetic brain disorder. Canavan disease. It is extremely rare – in fact, so rare that there is no reliable understanding of how many children are born with the disease. Relatively few researchers have studied Canavan, and there are no approved drugs to treat it.

The Landsmans refused to accept the doctors’ advice to make their sons comfortable until they died. Instead, they learned: there might be a way to correct genetic errors in boys’ brains. But the family will have to pay for it themselves. And it will be very expensive.

The Landsmans discovered gene therapy, a technology that uses viruses to add healthy genes to defective cells. The medical logic of technology is especially irresistible to parents whose children have the rarest diseases on earth, because it suggests the optimal way to correct errors. The question is: who will pay? Read full story.
