A SpaceX Dragon capsule that set down in the Pacific Ocean on Tuesday after having been docked at the International Space Station since late July became the first such vehicle to do three of those trips. SpaceX uses its Dragon cargo capsule to ferry experiment materials, supplies and more to and from the ISS, and it also refurbishes and reflies these capsules when possible as part of its ongoing mission to make spaceflight more reusable, and therefore more economical.

After it splashed down yesterday, SpaceX recovered the capsule from the ocean and returned it to shore. The vehicle is loaded with return cargo from the ISS, with almost 2,700 pounds of materials and results from experiments, which NASA staff on the ground will now examine and study. Dragon carried more than 5,000 pounds of stuff to the Space Station, and over half of that was related to science and research missions. One of the return cargo items is actually a spherical robot called CIMON, and is basically a space-based smart speaker companion.

The first international case of listeriosis linked to an outbreak in Spain that has sickened almost 200 people and killed two is being investigated by British public health officials.

The outbreak has been traced to contaminated chilled pork products under the brand “La Mechá” made by Magrudis, based in Seville. The potential infection is in a man from England who ate the product in Seville in mid-August. He was treated at a hospital in France before returning to the United Kingdom.

A Public Health England spokeswoman told Food Safety News the agency does not disclose patient details so she was not able to provide information on the age of the man or where in England he lives.

Researchers created ‘fettuccini-like silicone fingers’ to capture fragile marine life without damaging it.

It’s official: Android 10, the next version of the Android operating system, ships 3 September 2019. Well, it’s semi-official, at least.

Mobile site PhoneArena reports that Google’s customer support staff let the date slip to a reader during a text conversation. Expect the operating system, also known as Android Q, to hit Google’s Pixel phones first before rolling out to other models. It will include a range of privacy and security improvements that should keep Android users a little safer.

Halo: The Master Chief Collection is already pretty content-rich, containing Halo: Combat Evolved, Halo 2, Halo 3, Halo 4, the Halo ODST singleplayer campaign, and soon, Halo: Reach. The collection, in addition to giving players an easy way to access most of the franchise’s classics, offers remastered visuals and improved matchmaking.

On August 22nd, spaceflight startup Momentus Space and launch heavyweight SpaceX announced the first public launch contract to fall under the umbrella of the latter company’s recently-announced Satellite Rideshare Program.

Meant to provide a reliable, consistent, and affordable form of shuttle-like access to orbit, SpaceX’s rideshare program will – pending demand – involve no less than one dedicated Falcon 9 launch per year, capable of placing 15+ metric tons (33,000+ lbs) into low Earth orbit. Although SpaceX’s rideshare proposal is far from revolutionary, the company’s contract with Momentus Space appears to be more than a basic launch service agreement, potentially opening doors for far more flexible rideshare launches in the future.

Since its November 2017 founding, Momentus Space has been able to put money where its mouth is far more so than any comparable space tug hopeful, of which there are several. The concept that has helped Momentus raise nearly $34M in just 1.5 years is relatively simple: build a spacecraft whose sole purpose is to propel other spacecraft to their final orbit(s).

Small-scale soft continuum robots capable of active steering and navigation in a remotely controllable manner hold great promise in diverse areas, particularly in medical applications. Existing continuum robots, however, are often limited to millimeter or centimeter scales due to miniaturization challenges inherent in conventional actuation mechanisms, such as pulling mechanical wires, inflating pneumatic or hydraulic chambers, or embedding rigid magnets for manipulation. In addition, the friction experienced by the continuum robots during navigation poses another challenge for their applications. Here, we present a submillimeter-scale, self-lubricating soft continuum robot with omnidirectional steering and navigating capabilities based on magnetic actuation, which are enabled by programming ferromagnetic domains in its soft body while growing hydrogel skin on its surface. The robot’s body, composed of a homogeneous continuum of a soft polymer matrix with uniformly dispersed ferromagnetic microparticles, can be miniaturized below a few hundreds of micrometers in diameter, and the hydrogel skin reduces the friction by more than 10 times. We demonstrate the capability of navigating through complex and constrained environments, such as a tortuous cerebrovascular phantom with multiple aneurysms. We further demonstrate additional functionalities, such as steerable laser delivery through a functional core incorporated in the robot’s body. Given their compact, self-contained actuation and intuitive manipulation, our ferromagnetic soft continuum robots may open avenues to minimally invasive robotic surgery for previously inaccessible lesions, thereby addressing challenges and unmet needs in healthcare.

Small-scale soft continuum robots capable of navigating through complex and constrained environments hold promise for medical applications (1–3) across the human body (Fig. 1A). Several continuum robot concepts have been commercialized so far, offering a range of therapeutic and diagnostic procedures that are safer for patients owing to their minimally invasive nature (4–6). Surgeons benefit from remotely controlled continuum robots, which allow them to work away from the radiation source required for real-time imaging during operations (5, 6).

Despite these advantages, existing continuum robots are often limited to relatively large scales due to miniaturization challenges inherent in their conventional actuation mechanisms, such as pulling mechanical wires or controlling embedded rigid magnets for manipulation. Tendon-driven continuum robots (7–10) with antagonistic pairs of wires are difficult to scale down to submillimeter diameters due to increasing complexities in the fabrication process as the components become smaller (11–13). The miniaturization challenges have rendered even the most advanced form of commercialized continuum robots, mostly for cardiac and peripheral interventions (14), unsuited for neurosurgical applications due to the considerably smaller and more tortuous vascular structures. Magnetically steerable continuum robots (15–19) have also remained at large scale because of the finite size of the embedded magnets required to generate deflection under applied magnetic fields.

Synthetic biological circuits are promising tools for developing sophisticated systems for medical, industrial, and environmental applications. So far, circuit implementations commonly rely on gene expression regulation for information processing using digital logic. Here, we present a different approach for biological computation through metabolic circuits designed by computer-aided tools, implemented in both whole-cell and cell-free systems. We first combine metabolic transducers to build an analog adder, a device that sums up the concentrations of multiple input metabolites. Next, we build a weighted adder where the contributions of the different metabolites to the sum can be adjusted. Using a computational model fitted on experimental data, we finally implement two four-input perceptrons for desired binary classification of metabolite combinations by applying model-predicted weights to the metabolic perceptron. The perceptron-mediated neural computing introduced here lays the groundwork for more advanced metabolic circuits for rapid and scalable multiplex sensing.
