An AI that can design new proteins could help unlock new cures and materials
What’s happened?: A new AI tool could help researchers discover previously unknown proteins and design entirely new ones. When harnessed, it could help unlock the development of more efficient vaccines, speed up research into cures for cancer, or lead to completely new materials.
How it works: ProteinMPNN, developed by a group of researchers from the University of Washington, offers scientists a tool that will complement DeepMind’s AlphaFold tool’s ability to predict the shapes of all proteins known to science. ProteinMPNN will help researchers with the inverse problem. If they already have an exact protein structure in mind, it will help them find the amino acid sequence that folds into that shape.
Why it matters: Proteins are fundamental to life, and understanding their shape is vital to working with them. Traditionally researchers engineer proteins by tweaking those that occur in nature, but ProteinMPNN will open an entire new universe of possible proteins for researchers to design from scratch.

“Fingerprints” of climate change are clear in Pakistan’s devastating floods
What we know: Climate change very likely intensified the South Asian monsoon that flooded 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 who use climate models, weather observations, and other tools to determine whether global warming increased the likelihood or severity of recent extreme weather events.
What we don’t know: Precisely how big a role climate change played isn’t clear. Using climate models to pinpoint global warming’s role in amplifying the full monsoon season has proved tricky, due to some combination of the wide variability in heavy rainfall patterns over long periods, natural processes at work that the models may not fully capture, and the weather quirks of the territory. And the country’s weather is likely to become even more extreme. Read the full story.

The big story
Two sick children and a $1.5 million bill: One family’s race for a gene therapy cure
October 2018
Jennie and Gary Landsman launched an online appeal to save their sons on Thanksgiving of 2017. In a moving video, the pair describe how their two sons, Benny, then 18 months, and Josh, four months—both have a fatal genetic brain disorder called Canavan disease. It’s ultra rare—so rare, in fact, that there is no reliable understanding of how many children are born with it. Relatively few researchers study Canavan, and no drugs are approved to treat it.
The Landsmans refused to accept the doctors’ advice to make their sons comfortable until they died. Instead, they learned: there may be a way to fix the genetic error in the boys’ brains. But the family would have to pay for it themselves. And it would be expensive.
The Landsmans had discovered gene therapy, technology that uses viruses to add healthy genes to cells with defective ones. The technology’s medical logic is especially irresistible for parents of children with the rarest diseases on earth, because it suggests the ultimate bug fix. The problem is: who will pay?
