From a Google AI that writes news articles to a robotic liver transplant, check out this week’s awesome tech stories from around the web.
You’ve probably heard about SpaceX’s plans to use its giant new Starship vehicle to land people on the Moon and Mars, send numerous Starlink satellites or large telescopes into space, or perhaps even serve as a high-speed point-to-point terrestrial transport for equipment or people.
There’s another application for SpaceX’s Starship architecture that the company is studying, and NASA is on board to lend expertise. Though still in a nascent phase of tech development, the effort could result in repurposing Starship into a commercial space station, something NASA has a keen interest in because there are no plans for a government-owned research lab in low-Earth orbit after the International Space Station is decommissioned after 2030.
The space agency announced last month a new round of agreements with seven commercial companies, including SpaceX. The Collaborations for Commercial Space Capabilities (CCSC) program is an effort established to advance private sector development of emerging products and services that could be available to customers—including NASA—in approximately five to seven years.
KUALA LUMPUR, July 20 (Reuters) — Malaysia has issued a license to Starlink, the satellite communications service started by Elon Musk, to provide internet services in the country, particularly in remote areas, its communications minister said on Thursday.
Minister Fahmi Fadzil said in a Facebook post that Starlink, which is operated by Musk’s SpaceX, would begin by providing its services to schools and higher education institutions.
The government was also prepared to work with satellite communications firms, including Starlink, to ensure 100 percent internet coverage in populated areas, Fahmi said.
Last night at 9:09 p.m. PT (04:09 UTC), SpaceX successfully launched 15 V2 mini Starlink satellites to low Earth orbit from Space Launch Complex 4 East at Vandenberg Space Force Base, California.
Following a last-second aborted launch attempt the previous night, SpaceX teams performed checkouts of the Falcon 9 and determined another attempt to launch the next-gen satellites was good to go. During the previous attempt, the launch was held early in the countdown due to a “perceived leak” in the second stage, then eventually, the automated abort at T-minus 5 seconds.

The technology is not aimed at streaming high-quality videos but is helping businesses become more competitive.
China built a whopping 600,000 5G base stations in the last three months as it raced to achieve its target of three million before the end of the year, the South China Morning Post.
5G is the terminology used to denote the fifth generation of mobile network technology that can support high-speed broadband internet with low latency. Unlike its predecessors, 5G mobile networks have massive network capacities and can deliver a uniform user experience.
We have implemented a nonlinear quadrature measurement of \(\hat{p}+\gamma {\hat{x}}^{2}\) using the nonlinear electro-optical feedforward and non-Gaussian ancillary states. The nonlinear feedforward makes the tailored measurement classically nonlinear, while the ancillary state pushes the measurement into highly non-classical regime and determines the excess noise of the measurement. By using a non-Gaussian ancilla we have observed 10% reduction of the added noise relative to the use of vacuum ancillary state, which is consistent with the amount of nonlinear squeezing in the ancilla. Higher reduction of the noise can be realized in the near future by a better approximation of the CPS using a superposition of higher photon number states38,42. We can now create broadband squeezed state of light beyond 1 THz8,9 and can make a broadband amplitude measurement on it with 5G technology beyond 40 GHz10, as well as a broadband photon-number measurement beyond 10 GHz11. Furthermore, the nonlinear feedforward presented here can be compatible with these technologies if an application specific integrated circuit (ASIC) is developed based on the FPGA board presented here. By using such technologies we can efficiently create non-Gaussian ancillary states with large nonlinear squeezing by heralding schemes36,43 even when the success rate is very low. It is because we can repeat heralding beyond 10 GHz and can compensate for the very low success rate.
When supplied with such high-quality ancillary state, this nonlinear measurement can be directly used in the implementation of the deterministic non-Gaussian operations required in the universal quantum computation. Our experiment is a key milestone for this development as it versatilely encompasses all the necessary elements for universal manipulation of the cluster states. Furthermore, this method is extendable to multiple ancillary states case in implementation of the higher-order quantum non-Gaussianity44 and multi-mode quantum non-Gaussianity45.
Our experiment demonstrates an active, flexible, and fast nonlinear feedforward technique applicable to traveling quantum states localized in time. If the nonlinear feedforward system is combined with the cluster states13,14 and GKP states19, all operations required for large-scale fault-tolerant universal quantum computation can be implemented in the same manner. As such, we have demonstrated a key technology needed for optical quantum computing, bringing it closer to reality.

Advantageously, the fabrication of OECTs, in particular of the conductive channel, is compatible with solution-based fabrication methods and additive manufacturing, enabling cost-efficient manufacturing and rapid prototyping on flexible substrates10. This opens new possibilities in terms of the combination of materials that can be used in the manufacturing of OECTs, in particular the use of degradable materials. Degradable electronics refer to electronic systems and components that can degrade in an environment of interest spontaneously, in a controlled amount of time, and without releasing byproducts that are harmful to that environment18. With concerning amounts of electronic waste being generated, as well as exploding numbers of connected Internet of Things (IoT) devices19, there is growing interest in transient electronic systems with a service life of a few days to a few months. Although advances have been made in the manufacturing of fully degradable functional devices, i.e. antennas20, batteries21 and physical as well as environmental sensors22,23, investigations into degradable biosensors remain relatively limited24.
Advances have been made in proposing new materials for the OECT terminals, in particular the gate electrode, as its properties play a key role in modulating the transistor’s behavior. While Ag/AgCl gates offer the advantage of being non-polarizable, Au gates present little electrochemical activity in the range of voltages typical for OECT-based biosensing. Au and PEDOT: PSS gates have been explored for OECT-based biosensors, with the advantage of expanding the possibilities for bio-functionalizing the gate electrode6,25. PEDOT: PSS gates and contacts have been investigated, simplifying notably their manufacturing26. An all-PEDOT: PSS OECT was presented and shown to measure dopamine concentrations reliably and specifically27. Various forms of carbon have also been investigated for the realization of gate electrodes for OECTs8. Activated carbon gates, for example, showed increased drain current modulation due to the large specific surface area of the carbon material9. Recently, screen-printed carbon-gated OECTs were shown to be suitable for the detection of uric acid after functionalization of the carbon gate with platinum and Uricase28. Transient or recyclable materials such as paper26 have been proposed as substrates for OECTs. Polylactic acid (PLA)24 and Poly(lactic-co-glycolic acid)29 (PLGA) have been studied as degradable substrates for OECTs30, as well as diacetate cellulose31. These studies, however, relied on non-degradable contacts for the operation of the printed OECTs. More recently, Khan et al.32 proposed a fully printed OECT on cellulose acetate (CA) for the selective detection of glucose. The OECT is made of degradable materials and CA is a biocompatible material that is suitable as a substrate for transient biosensors.
In this work, we present disposable and biocompatible OECTs based on carbon, PEDOT: PSS and PLA as substrate. Challenges in the fabrication of transient electronic devices come from the low-temperature tolerance18 of biopolymeric substrates and reaching adhesion of the PEDOT: PSS channel material on the biopolymer33, which is often deposited from an aqueous solution. A fully additive fabrication process is developed to address these challenges, leveraging screen and inkjet printing. The influence of the gate material choice, as well as the gate geometry, are studied, and these parameters are optimized for the fabrication of transient OECTs for ions and metabolite sensing. The transistor characteristics of the devices as well as their sensing behavior and reproducibility are characterized. Finally, the degradable OECTs are integrated with highly conductive transient zinc metal traces, which are of interest for interconnection with other degradable electronic circuits and could allow, for example, the wireless operation of the biochemical chemical sensors34.
