Microsoft shut down Internet Explorer, but its ghosts will remain with time

Even though the browser is inactive, it can continue to be a gateway for computer attacks, especially in institutions where updates are not as regular.

After years of uselessness and decline in recent months Internet Explorer finally came to an end, marking a turning point for Microsoft and one of its most famous products. Originally released in 1995, Internet Explorer has been preinstalled on Windows computers for nearly two decades and, like Windows XP, has become pillar – to the point that when it came time for users to upgrade and upgrade to newer browsers, they often didn’t.

Despite the end introduced by the North American giant last week pushed users beyond historical browsersecurity researchers warn that security vulnerabilities are far from gone, website notes Wired.

In the coming months, Microsoft will disable the IE app on Windows 10 devices, directing users to their browser. edge the next generation, first released in 2015. However, the Internet Explorer icon will remain on users’ computers, and Edge will now include a service called “modo IEto keep access to old websites created for Internet Explorer.

Seven years after Edge’s debut, analysis computer industry indicates that Internet Explorer, as outdated as it may seem to some, may still account for more than 5% of the total global browser market share, and in the United States of America this share may be closer to 2%.

For a product that has been on the market for as long as IE, backwards compatibility something hard to find. “We can’t forget that some parts of the Internet still depend on the specific behavior and characteristics of Internet Explorer,” he explained. Sean LinderseyHead of Microsoft Edge Enterprise.

On the other hand, the official added that real need restarting with Edge instead of reviving Internet Explorer. “The Internet has evolved, as have browsers. The incremental improvements to Internet Explorer have not been able to match the general improvements to the Internet as a whole, so We have begun again”.

Microsoft explained that it will continue to support the browser engine behind Internet Explorer, known as “MSHTML”, and is looking at versions of Windows that are still “used in critical environments.” But Maddy Stone, a researcher who is part of the Google Vulnerability Group, notes that hackers are still exploit vulnerabilities Internet Explorer in real attacks. “Internet Explorer remains a mature attack surface for initial penetration on Windows machines, even if the user does not use Internet Explorer as their Internet browser.”

In his review, Stone specifically noted that while the number of new Internet Explorer vulnerabilities has remained fairly constant, over the years, attackers have increasingly attacked the MSHTML browser engine with malicious files such as Office documents. This may mean that sterilizing the IE application won’t change immediately attack tendencies that are already in motion.

It goes without saying that for a browser considered dead, Explorer still takes many alive.

Better Organ Preservation Through Advances in Cryopreservation

The development of cryopreservation technology has made it possible to rapidly advance in reproductive technologies, stem cell therapy, and even save species from extinction.

However, as part of the cryopreservation process, agents are added to protect cells from damage and dehydration during the freezing process. Physical Organization.

The two main agents used in cryopreservation in recent decades are dimethyl sulfoxide and glycerol, both of which are toxic.

These agents are also unsuitable for hundreds of cells, and so far preservation of organs and tissues has not been achieved. Because of this, up to 60% of donor hearts and lungs are discarded.

“We have a lot of organs, but most of them are just thrown away,” says RMIT’s Saffron Bryant, principal investigator on the new study. “We only have a few hours to transfer an organ from a donor to a recipient.”

The research team analyzed the effectiveness of eutectic solvents as cryoprotectants. They compared it to six different solvents in mammalian cells and tested thermal properties, toxicity, and permeability in four mammalian cell types, including skin and brain.

The researchers determined that a eutectic solvent made from proline and glycerol was the most effective cryoprotectant. effective for mammalian cells.

This solvent was also less toxic than when its components were used alone, highlighting the potential for optimizing cryopreservation using combined agents.

These cryoprotective agents can even be tailored to specific cell types and thousands of combinations could potentially be developed.

The team also did increase incubation time cells with this new cryopreservative, according to the results of the study, published no Journal of Chemistry of Materials B.

“Incubating these cells with cryoprotectant at 37°C for several hours before freezing and maintaining their viability is an important step in organ and tissue storage,” says Bryant.

“This means that we can expose organs to cryoprotectants long enough for them to penetrate deeper layers of the organ without causing damage,” he says.

s o 1850 people on the waiting list for organ transplants in Australia and more than 100,000 people awaiting transplants in the US, these new cryoprotectants could help keep donor organs viable for years, not hours.

“We have a long way to go in our studies because we only looked at individual cells, and for organs it is a much more complex process,” adds Bryant.

“But if we can create this approach to storing organs, we can eliminate their shortage – no queue“, he concludes.

Pixel 4 gets an update from Google ahead of time

Android 13 Pixel 4 Google atualização beta

Android 13 is being developed at a good pace, Google periodically releases new test versions, as expected. This system is expected in late summer to update Google smartphones first.

Still without a planned and expected release date, now a contingency arose. Unexpectedly, a Pixel 4 user received an update to Android 13, even though it is a beta version.


Google has an open testing program that anyone who wants to try Android 13 can use. It's not limited to just pixels, but has opened it up to several models from other brands so that they can evaluate this version.

What the user of this Pixel 4 did not expect is that their smartphone will receive Android 13 version TP1A.220603.002.A1. Apparently, this is reserved for Google internal testing and should not have been available outside the company.

Even stranger and even more ridiculous is that this user did not register their Pixel 4 in any of the Android 13 tests. Thus, they were far from accessing this or any other version of the new Google system that was not even released. more. .

In the description he provided on various internet channels, the owner of this Pixel 4 said that he had problems with the smartphone from that moment on. The worst of them was even a clear incompatibility with the Play Store. Reinstalling the app and even resetting the Pixel 4 didn't fix the problem.

Even though this seems to be the only known case with Android 13, this is a seemingly normal situation. In previous years and in different versions, there were reports of situations where users of Pixel smartphones inadvertently received updates.

With Android 13 almost ready, Google is accelerating its pace of development. The final version should appear soon, thus paving the way for the expected update, both for the Pixel and for all other smartphones in the Google system.

Blocks R21

Blocks R21

Portuguese 3D printer startup Blocks will release a new model, the Blocks R21, which is due to hit the market in September. Fortunately, we were able to test the device already in its final version, which showed an impressive evolution compared to the previously tested model. One MKII.

This new printer features an all-aluminum construction, an LCD touch panel that allows you to control all printer settings. Among them is the calibration of the print tray, which, in addition to heating, has a metal coating with a texture that greatly contributes to the adhesion of the filament during printing.

Another important detail is the integration of all the main printing elements in one module, such as a two-block extruder and a hot end. The latter has a threaded screw for quick replacement, which allows you to replace the module with another one with a nozzle that is compatible with a particular type of filament. The variation can be from 0.2 to 1 mm – the hot end supplied with the printer is equipped with a 0.4 mm nozzle. This is to provide better print quality based on filament type, from traditional PLA to ABS, Flex, PETG, nylon, fiberglass, carbon fiber reinforced PET, PLA with metal or wood.

In terms of use, the Blocks R21 couldn’t be simpler and more intuitive thanks to the aforementioned LCD touch screen and a new tray that is easy to calibrate and requires a minimum amount of glue liquid (varnish). The fact that it uses an almost closed rigid construction, together with the integration of all units into a single module, made it feel quieter: it was even the quietest I have tested to date. Blocks R21 is priced to be considered “premium” and is available in a basic version, already with all the accessories you need to get started printing right away. However, we can buy it with an optional connection kit which, while pushing the price up to a less than pleasant €1,800, adds a Wi-Fi controller, webcam and temperature sensor so you can monitor print status remotely.
