DoorDash is testing a feature that lets you return packages to post offices, FedEx, or UPS (3 minute read)
DoorDash is testing a feature called 'Return a Package' that allows customers to book a delivery person to return packages to the nearest post office, UPS, or FedEx location. Customers will have to have their packages fully sealed with the prepaid shipping label attached before collection. DoorDash Dashers will be paid the same way for Return a Package returns as they would be for any other marketplace order. Other companies have tested similar services in the past but weren't successful.

Apple's refusal to use the RCS standard for messaging has resulted in many users turning to third-party messaging apps. Details about the improvements to Google's Messaging app are available in the article.
A transistor made using two atomically thin materials sets size record (9 minute read)
A new record for the smallest transistor gate length has been achieved. The gate was only a single carbon atom across. The design of the whole transistor is easy to make and relatively compact. While the transistor will need more work to improve its performance, the techniques used to create it are significant as they do not require extremely precise positioning of the atomically thin materials.
A new type of killer T-cell can stop attacks on healthy tissue (3 minute read)
A new form of human T cell that suppresses attacks on healthy tissues has been discovered. T cells play a significant role in the adaptive immune response. The new T cells may be capable of killing other T cells. They were first discovered in mice, but a new study confirms that the cells also exist in humans. Enhancing the number of these T cells in the body could aid in the treatment of infections and autoimmune diseases.

How to use undocumented web APIs (8 minute read)
The information browsers send to the backend are just HTTP requests. There's no way for the backend to tell that a request isn't sent by a browser unless too many headers are removed. This article shows how anyone can access undocumented APIs by sending requests to endpoints authenticated with cookies. It uses Google Hangouts as an example and then points out some of the issues with the technique.
Your Brain Is Fooled Into Feeling Shapes and Textures On This Temperature-Changing Touchscreen (3 minute read)
Researchers from Texas A&M University have developed a touchscreen device that can increase its surface friction to create the illusion of physical shapes and textures when touched. The amount of friction on the screen can be controlled through temperature. Current prototypes aren't able to make detailed temperature adjustments, but the team hopes to eventually develop touchscreen devices that can trick the brain into thinking it is feeling real physical buttons.
