3D Systems announces breakthrough in bioprinting technology and expansion of its regenerative medicine initiative...

3D Systems, the company that released the first commercial 3D printer, has announced a breakthrough in bioprinting technology that could enable 3D printing of regenerative tissue. 

The US-based firm is set to significantly expand its development efforts in regenerative medicine and bioprinting solutions, a decision that was driven by the progress made in collaboration with United Therapeutics Corporation and its organ manufacturing and transplantation-focused subsidiary, Lung Biotechnology PBC, on the development of 3D printing systems for solid-organ scaffolds. 

As part of the plans 3D Systems will invest, develop, and commercialize solutions for a variety of applications n regenerative medicine, including the development of non-solid organ applications. 

In 2020, 3D Systems and United Therapeutics achieved significant progress in the development of a next-generation manufacturing platform solution for lung scaffolds. This is capable of full size, vascularized, micron-level printing. Combined, the two companies have made advances in lung modelling, 3D printing, as well as material formulation using a unique rhCollagen, used in tissue regeneration. 

The firm’s newly developed Print to Perfusion™ process enables 3D printing of high-resolution scaffolds that can be suffused with living cells to create tissues. 3D Systems is also expanding its high-speed Figure 4® technology through innovation tailored to bioprinting and regenerative medicine. 

Building on these capabilities, 3D Systems and its partners will be able to advance innovation into numerous applications within the human body. The company also believes this gives them the potential to enable novel laboratory testing methods to accelerate the development of new drug therapies while reducing the need for animal testing.

Chuck Hull, co-founder, executive vice president and chief technology officer, 3D Systems said: “Over the last years as bioprinting and regenerative medicine have evolved, we’ve seen a growing need to place cells at high-resolution in a nurturing matrix to produce complex tissues. 

“Precise 3D printing with hydrogels, followed by perfusion of cells into the printed scaffold is the best way to achieve this, and we are thankful our work with United Therapeutics has given us the opportunity to advance and perfect this technology.”

Peloton vulnerable to cyber attacks, McAfee research finds

​​​​​​​Software security experts McAfee discovered exercise bikes by Peloton are vulnerable to cyber attacks, which the company have since resolved 

Peloton, the popular exercise bikes, were found to be vulnerable to cyber attacks in the latest research from McAfee. 

Peloton is a brand of electric bikes that combines high end exercise equipment with cutting-edge technology. Its products use wi fi to connect to a large tablet that interfaces with the components of the exercise device, and provides an easy way for physical activity enthusiasts to attend virtual workout classes over the internet several times a week.

Peloton has garnered attention recently around the privacy and security of its products. So McAfee decided to take a look for themselves and purchased a Peloton Bike+.

The problem

Researchers looked at the Android devices and uncovered a vulnerability  that could allow an attacker with either physical access to the Bike+ or access during any point in the supply chain to gain to hack into the bike’s tablet, including the camera, microphone and personal data. 

For the person using it there would be no indication the Bike+ has been tampered with, potentially putting Peloton’s 16.7 million users at risk.  

The flaw was found in the Android Verified Boot (AVB) process. McAfee researchers were able to bypass the Android Verified Boot process, which normally verifies all code and data before booting. They were then able to get the device to boot bypassing this step. 

This could potentially lead to the Android OS being compromised by an attacker who is physically present. Even worse, the attacker could boot up the Peloton with a modified credential to gain privileges, granting them access to the bike remotely. 

As the attacker never has to unlock the device to boot it up, there would be no trace of their access on the device. This type of attack could also happen at any point from construction to warehouse to delivery, by installing a backdoor into the Android tablet without the user ever knowing. 

The solution

Given the simplicity and criticality of the flaw, McAfee informed Peloton while auditing was ongoing. The vendor was sent full details,  and shortly after, Peloton confirmed the issue and released a fix for it. 

Further conversations between McAfee and  Peloton confirmed that this vulnerability had also been present on the Peloton Tread exercise equipment. 

Peloton’s Head of Global Information Security Adrian Stone, commented on the research: “This vulnerability reported by McAfee would require direct, physical access to a Peloton Bike+ or Tread. Like with any connected device in the home, if an attacker is able to gain physical access to it, additional physical controls and safeguards become increasingly important.

"To keep our members safe, we acted quickly and in coordination with McAfee. We pushed a mandatory update in early June and every device with the update installed is protected from this issue.”
