New study unveils epigenetic 'traffic lights' controlling stop and go for gene activity      (via sciencedaily.com) 

A major new study reveals a 'traffic light' mechanism controlling genetic activity within cells -- a system which could potentially be targeted by cancer drugs already in development. The research describes how 'epigenetic' changes to the structure of DNA can act as a stop-go signal in determining whether a gene should be read. Unlike our genetic make-up, which is well understood, the world of epigenetics is still largely unexplored and referred to as the 'dark matter' of the genome.

Cells avoid multitasking      (via sciencedaily.com) 

Textbooks will tell you that in dividing cells, production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level. Molecular biologists have now discovered that this is not true: protein synthesis shows two peaks and lipid synthesis peaks once.

Successful cure of HIV infection after stem cell transplantation, study suggests      (via sciencedaily.com) 

Haematopoietic stem cell transplantation for the treatment of severe blood cancers is the only medical intervention that has cured two people living with HIV in the past. An international group of physicians and researchers has now identified another case in which HIV infection has been shown to be cured in the same way. The successful healing process of this third patient was for the first time characterized in great detail virologically and immunologically over a time span of ten years.

First wearable device for vocal fatigue senses when your voice needs a break      (via sciencedaily.com) 

Researchers have developed the first smart wearable device to continuously track how much people use their voices, alerting them to overuse before vocal fatigue and potential injury set in. The soft, flexible, postage-stamp-sized device comfortably adheres to the upper chest to sense the subtle vibrations associated with talking and singing. From there, the captured data is instantaneously streamed via Bluetooth to the users' smartphone or tablet, so they can monitor their vocal activities in real time throughout the day and measure cumulative total vocal usage. Custom machine-learning algorithms distinguish the difference between speaking and singing, enabling singers to separately track each activity.

The roar and crackle of Artemis 1      (via sciencedaily.com)     Original source 

When the Artemis 1 mission was launched in November, it became the world's most powerful rocket, and with liftoff came a loud roar heard miles away. Researchers report noise measurements during the launch at different locations around Kennedy Space Center. The data collected can be used to validate existing noise prediction models, which are needed to protect equipment as well as the surrounding environment and community.
