Did black holes form immediately after the Big Bang? How did supermassive black holes form? What is dark matter? In an alternative model for how the Universe came to be, as compared to the ‘textbook’ history of the Universe, a team of astronomers propose that both of these cosmic mysteries could be explained by so-called ‘primordial black holes’. In the graphic, the focus is on comparing the timing of the appearance of the first black holes and stars, and is not meant to imply there are no black holes considered in the standard model.

Imagine that your team is meeting to decide whether to continue an expensive marketing campaign. After a few minutes, it becomes clear that nobody has the metrics on-hand to make the decision. You chime in with a solution and ask Amazon’s virtual assistant Alexa to back you up with information: “Alexa, how many users did we convert to customers last month with Campaign A?” and Alexa responds with the answer. You just amplified your team’s intelligence with AI. But this is just the tip of the iceberg.

Intelligence amplification is the use of technology to augment human intelligence. And a paradigm shift is on the horizon, where new devices will offer less intrusive, more intuitive ways to amplify our intelligence.

Hearables, or wireless in-ear computational earpieces, are an example of intelligence amplification devices that have been adopted recently and rapidly. An example is Apple’s AirPods, which are smart earbuds that connect to Apple devices and integrate with Siri via voice commands. Apple has also filed a patent for earbuds equipped with biometric sensors that could record data such as a user’s temperature, heart rate, and movement. Similarly, Google’s Pixel Buds give users direct access to the Google Assistant and its powerful knowledge graph. Google Assistant seamlessly connects users to information stored in Google platforms, like email and calendar management. Google Assistant also provides users with highly-personalized recommendations, helps automate personal communication, and offloads monotonous tasks like setting timers, managing lists, and controlling IoT devices.

HONG KONG, Dec 17 (Reuters Breakingviews) — After conquering semiconductors, Taiwan Semiconductor Manufacturing, the world’s biggest chipmaker has a new challenge: kickstarting Taiwan’s stalled green transition. Bureaucracy and red tape have marred the island’s renewable-energy goals. The company’s (2330.TW) voracious appetite for cleaner power will offer a much-needed spark.

Referendums on whether to restart a nuclear power plant and whether to change the location of a planned $2 billion liquid fossil gas terminal highlight how politically contentious the island’s energy issues are. President Tsai Ing-wen has pledged to phase out nuclear power and is hoping gas-fired plants will supply half of the $600 billion economy’s electricity needs by 2025. At the same time, she has promised to increase the share of renewable sources to 20%, from 5.4% in 2020.

On paper that’s doable, but in practice it looks increasingly out of reach. Covid-19 disruptions held up wind and solar projects, but lengthy and complex approval processes are also to blame. Offshore wind developers, for instance, must obtain consent letters from at least eight different authorities as well as approval from the environmental watchdog even to be eligible to bid for projects. Those that make it to the second round must also detail how they can meet local procurement requirements, often onerous criteria given how new the industry is in Taiwan. According to one 2021 estimate, unfinished wind and solar projects totalled $83 billion, among the highest in Asia.

A vast system of canyons that dramatically scars the face of Mars could be harboring reserves of hidden water.

An unusually high quantity of hydrogen has been detected in the heart of the 4,000 kilometers (2,485 miles) of canyons known as Valles Marineris, nicknamed the Grand Canyon of Mars. We know this thanks to new data from the ESA-Roscosmos ExoMars Trace Gas Orbiter’s FREND instrument.

The finding suggests that, at depths up to a meter (three feet) below the surface, the soil in the region is rich in water, either bound up in minerals or as subsurface water ice, potentially offering a new way of locating the precious stuff on the apparently extremely arid world.

Cybersecurity researchers have demonstrated a new attack technique that makes it possible to leverage a device’s Bluetooth component to directly extract network passwords and manipulate traffic on a Wi-Fi chip, putting billions of electronic devices at risk of stealthy attacks.

The novel attacks work against the so-called “combo chips,” which are specialized chips that are equipped to handle different types of radio wave-based wireless communications, such as Wi-Fi, Bluetooth, and LTE.

“We provide empirical evidence that coexistence, i.e., the coordination of cross-technology wireless transmissions, is an unexplored attack surface,” a group of researchers from the Technical University of Darmstadt’s Secure Mobile Networking Lab and the University of Brescia said in a new paper.

In recent years, engineers have been trying to develop more effective sensors and tools to monitor indoor environments. Serving as the foundation of these tools, indoor positioning systems automatically determine the position of objects with high accuracy and low latency, enabling emerging Internet-of-Things (IoT) applications, such as robots, autonomous driving, VR/AR, etc.

A team of researchers recently created CurveLight, an accurate and efficient positioning system. Their technology, described in a paper presented at ACM’s SenSys 2021 Conference on Embedded Networked Sensor Systems, could be used to enhance the performance of autonomous vehicles, robots and other advanced technologies.

“In CurveLight, the signal transmitter includes an infrared LED, covered by a hemispherical and rotatable shade,” Zhimeng Yin, one of the researchers who developed the system at City University of Hong Kong, told TechXplore. “The receiver detects the light signals with a photosensitive diode. When the shade is rotating, the transmitter generates a unique sequence of light signals for each point in the covered space.”

For all that neural networks can accomplish, we still don’t really understand how they operate. Sure, we can program them to learn, but making sense of a machine’s decision-making process remains much like a fancy puzzle with a dizzying, complex pattern where plenty of integral pieces have yet to be fitted.

If a model was trying to classify an image of said puzzle, for example, it could encounter well-known, but annoying adversarial attacks, or even more run-of-the-mill data or processing issues. But a new, more subtle type of failure recently identified by MIT scientists is another cause for concern: “overinterpretation,” where algorithms make confident predictions based on details that don’t make sense to humans, like random patterns or image borders.

This could be particularly worrisome for high-stakes environments, like split-second decisions for self-driving cars, and medical diagnostics for diseases that need more immediate attention. Autonomous vehicles in particular rely heavily on systems that can accurately understand surroundings and then make quick, safe decisions. The network used specific backgrounds, edges, or particular patterns of the sky to classify traffic lights and street signs—irrespective of what else was in the image.
