Post-mortem changes may shed light on important brain studies (3 minute read)
Certain cells in the human brain remain active for hours after we die. Some even increase their activity and grow to gargantuan proportions. Inflammatory cells called glial cells grow and sprout long arm-like appendages for many hours after death. The cells' job is to clean up things after brain injuries, so it isn't too surprising that they enlarge after death. Most studies that use post-mortem human brain tissues do not account for post-mortem gene expression or cell activity. These new findings mean that future studies will have to take into account these genetic and cellular changes and try to minimize them.
‘Last Hope’ Experiment Finds Evidence for Unknown Particles (15 minute read)
Muons are elementary particles similar to electrons. Decades ago, scientists noticed that these particles wobbled more than expected when whipping around a magnetized ring. A recent new measurement confirms these results, making it significantly likely that an unknown force was giving the muons an extra push. The discovery, if confirmed, could break down the 50-year-old Standard Model of particle physics, which describes known elementary particles and interactions.

Learning COBOL: A Journey For The Modern Programmer (12 minute read)
This article is an introduction to learning COmmon Business Oriented Language (COBOL). COBOL is a domain-specific language for business. It excels in managing and manipulating heterogeneous data in record structures, using true fixed point decimal arithmetic, and fast access to externally stored record structures. COBOL is different from what most programmers are used to as it is mostly used to operate on records. Working with COBOL likely means that the developer will need to learn how to operate a mainframe.
BleedingTooth: Linux Bluetooth Zero-Click Remote Code Execution (27 minute read)
This blog post describes the process of discovering high severity vulnerabilities in the Linux Bluetooth stack and then chaining them into a remote code execution exploit targeting Ubuntu systems. The exploit allows unauthenticated remote attackers to execute arbitrary code with kernel privileges on vulnerable devices within short distances. As a result of this discovery, the Bluetooth High Speed feature is now disabled by default.
Ask HN: What tech job would let me get away with the least real work possible? (HackerNews Thread)
The pandemic has made some realize different priorities in life. Work and building a career is no longer a priority for some. However, everybody needs shelter, calories, and resources, so income is still necessary.
