A medical robot can guide a flexible needle through the lungs of living pigs without requiring human surgeons to directly control the robot’s actions. Over several additional tests on lungs removed from the pigs, the robot placed the needle more precisely than human doctors using a standard straight needle procedure.

“There are many procedures, including biopsy or directed drug delivery or localised radiation cancer treatment, that involve using a needle to get to a specific target to perform the procedure where you’re manoeuvring that needle inside …

An Existentialist Guide to Feeling Nothing

In retrospect, the title alone should have been a sufficient warning: Jeanne Dielman, 23 Quai du Commerce, 1080 Bruxelles . Alas, I’m old enough to be a bit nostalgic about massive telephone address books. And massive it is.

What Are SQL Stored Procedures and How Do You Create Them?

Stored procedures: like functions for your SQL. A stored procedure is a batch of SQL statements created and stored on a database. You can reuse a stored procedure over and over again. A stored procedure can accept parameters, run a query, and return results. Many users can call a stored procedure and different applications can call it with different parameter values. What Are the Benefits of Using Stored Procedures? Apart from allowing multiple users and applications to reuse it, a stored procedure has other benefits. It is easy to modify. You can change a stored procedure when necessary and these updates will be reflected for all users. Furthermore, you don’t need to redeploy your application when you modify the stored procedure. It reduces network traffic because the server only passes the procedure’s name over the network and not the entire query. It improves database security since users don’t have direct access to tables. To make...
