There was a known issue with xchroot v2.7.4 under Mageia 8: When xchroot did change the user no X-connection could be made without a manual xhost +SI:localuser:»targetUser« or xhost +local:. This was because Mageia did not provide an xauth token that matched the hostname likely due to an invalid /etc/hostname file. Now xchroot can generate an xauth token for the target user if none should be provided at invocation. The xauth mechanism was completely rewritten. It shall now be more stable. If there is a stale lock on the Xauthority file which makes xchroot hang you can now press Ctrl-C to force the retraction of this lock and make xchroot succeed (Otherwise xauth will display an error message after a while if it gives up on getting the lock.). Only the xauth token for the target hostname and the target display will be passed on to the chroot environment unless --alldisplays is given. The chroot environment will always have an xauth token even if the user should issue an xhost -local: later on.
The rinse aid shall achieve that your dishes shine beautifully when they come out of the dishwasher. According to a study by the University of Zurich, which has just been published in the “Journal of Allergy and Clinical Immunology”, a common ingredient in rinse aid, the alcohol ethoxylate, damages the intestinal epithelium. It is the cell layer that lines the intestine and controls, what can get into the body’s interior. A defect in this barrier is associated with diseases such as food allergies, gastritis, diabetes, obesity, liver cirrhosis, rheumatoid arthritis, multiple sclerosis, autism spectrum disorders, chronic depression, and Alzheimer’s disease. Similar protective layers can be found on the skin and in the lungs. At a high dose of alcohol ethoxylate, the epitelle cells died off in the test, at a lower one they became more permeable, so that harmful substances can enter the body. Particularly affected are commercial dishwashers, which usually do not have a sufficient rinse program to remove the rinse aid from the dishes after washing. Vinegar or citric acid are recommended as alternatives if you don’t want to do without the rinse aid at first hand.
The company Moderna has successfully completed its phase 2 study for an mRNA vaccine against skin cancer in 157 patients. They were 44% less likely to die from cancer or have a recurrence. The vaccination is individually adapted to the respective tumor and its characteristic proteins. It currently takes eight weeks from the biopsy of the melanoma to the finished vaccination, but Moderna wants to shorten this period to four weeks. In as little as 3 years, when the phase 3 trials shall be complete, there could be a vaccination ready for the market. There are preparations to test the vaccination also against lung and stomach cancer, which are said to pose a harder target. Besides Moderna, Biontech is also developing a cancer vaccine.
