Best bug tracking software tools and systems: track defects efficiently with these top tools.

We are testers – in other words, bug finders. Defect/Bug/Issue/Fault/Failure/Incident – whatever we choose to call – our primary job description revolves around finding, recording, reporting, managing and tracking these. There is no harm in using an excel sheet to record/track and emails to report/alert/communicate.

At the Association for Computing Machinery’s Programming Language Design and Implementation conference this month, MIT researchers presented a new system that repairs dangerous software bugs by automatically importing functionality from other, more secure applications.

Remarkably, the system, dubbed CodePhage, doesn’t require access to the source code of the applications whose functionality it’s borrowing. Instead, it analyzes the applications’ execution and characterizes the types of security checks they perform. As a consequence, it can import checks from applications written in programming languages other than the one in which the program it’s repairing was written.

Black holes may not end in a crushing singularity as previously thought, but rather open up passageways into whole other universes.

Scientists show how quantum computing could be a game-changer in our understanding of quantum processes.

Images from the eROSITA telescope reveal X-ray–emitting blobs surrounding gamma-ray bubbles.

Michigan State University researchers have discovered that one of the most important reactions in the universe can get a huge and unexpected boost inside exploding stars known as supernovae.

This finding also challenges ideas behind how some of the Earth’s heavy elements are made. In particular, it upends a theory explaining the planet’s unusually high amounts of some forms, or isotopes, of the elements ruthenium and molybdenum.

“It’s surprising,” said Luke Roberts, an assistant professor at the Facility for Rare Isotope Beams and the Department of Physics and Astronomy, at MSU. Roberts implemented the computer code that the team used to model the environment inside a supernova. “We certainly spent a lot of time making sure the results were correct.”

The exact gene that caused stem cell aging has been identified.

Above – When mesenchymal stem/stromal cells (MSCs) age, the transcription factor GATA6 is increasingly produced in the cell to induce aging response. By transcription factor-based cellular reprogramming, aged MSCs are rejuvenated with a reduction in GATA6 effects on cellular aging. CREDIT AlphaMed Press

A shirt that monitors your blood pressure or a pair of socks that can keep track of your cholesterol levels might be just a few years away from becoming reality.

In an article published in Applied Physics Reviews, researchers examine the use of microfibers, and even smaller nanofibers, as wearable monitors that could keep track of a patient’s vital signs.

The microfiber- and nanofiber-based technology addresses growing concerns in the medical community about monitoring chronic illnesses like diabetes, asthma, obesity, and high blood pressure as the population ages.

Spider silk is a protein fiber spun by spiders, which they use to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to float through the air, or to glide away from predators.

Each spider and each type of silk has a set of mechanical properties optimized for their biological function, but in particular, their dragline silks, have exceptional mechanical properties. They exhibit a unique combination of high tensile strength and extensibility which enables a silk fiber to absorb a large amount of energy before breaking with this estimated tensile strength several times that of steel.
