The U.S. military wants to understand the most important software on the planet

It’s no exaggeration to say that the whole world is built on the Linux kernel – even though most people have never heard of it.

It is one of the first programs that most computers load when they start up. It enables the hardware that runs a machine to interact with software, control the use of its resources, and serve as the basis for an operating system.

It’s the core building block of nearly all cloud computing, nearly every supercomputer, the entire Internet of Things, billions of smartphones, and more.

But the kernel is also open source, which means anyone can write, read and use its code. That worries cybersecurity experts within the U.S. military. Its open-source nature means that the Linux kernel — and many other critical open-source software — is exposed to malicious manipulation in ways we still barely understand. Read the full article.

Heat is not good for plant health. Here’s how gene editing can help.

news: Some of the world’s most productive agricultural regions have already broken temperature records this year, which could have worrying effects on food supplies. Even a slight increase in temperature can make crops more vulnerable to pests. To address this, the researchers identified a gene that appears to be the culprit in temperature sensitivity, and found a way to repair the plant’s immune system at higher temperatures.

How they do it: For many plants, an important immune pathway involves salicylic acid. The chemical has antibacterial properties, and it also acts as a signal to initiate other immune pathways. However, this pathway essentially shuts down under unusually hot conditions. The researchers were able to tweak the genomes of plants so that they produce more salicylic acid, thereby enhancing the plants’ protection against pests and diseases.

What does it mean: Although the experiment was conducted in a Arabidopsis Plants, including many others including wheat, corn and potatoes, share the same salicylic acid pathway, making this work potentially impactful far beyond the lab. Read the full article.

Why Gen Z is falling for online misinformation

June 2021

In November 2019, a TikTok video claiming that “Trump” would carry out mass murders of LGBT individuals and people of color if Joe Biden were elected president of the United States quickly went viral and was viewed and shared by hundreds of thousands of people , likes and comments young people.

Obviously, these claims are false. So why are so many members of Gen Z (a label that applies to people around the age of 9 to 24 who are probably more digitally savvy than their predecessors) falling into such blatant misinformation? That’s partly because young people are more likely to believe and pass on misinformation if they share a sense of identity with the person who originally shared the information.
