Apple has acquired a startup with technology that could turn iPhones into mobile payment terminals. Montreal-based Mobeewave has tech that requires only an NFC chip to work, allowing users to tap either their smartphone or a credit card to another phone for payment processing. NFC chips have been included in iPhones since the iPhone 6. And while Apple Pay lets shoppers tap their iPhones to pay at a retail store, adding Mobeewave could allow any iPhone to accept payments without extra hardware like a card reader. Apple paid about $100 million for Mobeewave, and has retained its team of employees.
Researchers have developed a machine learning system that can either make a prediction about a task, or defer the decision to an expert. Most importantly, it can adapt when and how often it defers to its human collaborator, based on factors such as its teammate’s availability and level of experience. The team trained the system on multiple tasks, including looking at chest X-rays to diagnose specific conditions such as atelectasis (lung collapse) and cardiomegaly (an enlarged heart). In the case of cardiomegaly, they found that their human-AI hybrid model performed 8 percent better than either could on their own (based on AU-ROC scores).
The freeze-dried agent, which has a physical consistency of cotton candy, can be stored at room temperature for several months and reconstituted in saline before injection. “Our goal was to give first responders a tool to stop internal bleeding that could be easily carried in a backpack or stored in an ambulance and, once injected intravenously in hemorrhagic patients, stop internal bleeding for a period long enough to get the patient to a hospital.” The researchers found that for traumatic injuries, the injection of HAPPI (Hemostatic Agents via Polymer Peptide Interfusion) increased the median survival rate beyond one hour — a critical goal for trauma care.
The new non-invasive experimental protocol developed by researchers was found to help prevent fear memories from returning. The protocol combines fear conditioning – a stimulus associated with something unpleasant, that induces a negative memory – and the neurostimulation of a specific site of the prefrontal cortex. This process alters the perception of an unpleasant (aversive) event so that it will no longer induce fear. “We’re dealing with a new technique that can be employed in different contexts and can assume a variety of functions, starting from treating PTSD, which will be the focus of our next study”.
Apple rode the company’s strong earnings report to become the world’s most valuable publicly traded company, surpassing the state oil giant Saudi Aramco. Apple shares closed up 10.47%, giving it a market valuation of $1.84 trillion. Saudi Aramco, which had been the most valuable publicly listed company since its market debut last year, now trails at $1.76 trillion as of its last close. The company has recovered from its pandemic low-point in March. Shares are up more than 44% this year. “Despite COVID-19 headwinds, Apple grew revenue in every segment and geography, beating consensus revenue by 14% as ecosystem engagement rises.”
Nvidia Corp. is in advanced talks to acquire Arm Ltd., the chip designer that SoftBank Group Corp. bought for $32 billion four years ago. This deal could be the largest ever in the semiconductor industry, with estimates stating that Nvidia would have to pay $55 billion for Arm. Nvidia is the largest maker of graphics processors and it’s spreading the use of the gaming component into new areas such as artificial intelligence processing in data centers and self-driving cars. Marrying its own capabilities with central processor units designed by Arm may enable it to take on Intel and Advanced Micro Devices in a more comprehensive way.
The United Arab Emirates has launched a nuclear energy plant on Saturday, the first such project in the oil-rich Arab world. Unit 1 is the first of the plant’s four nuclear reactors to launch. The corporation said the construction of Unit 2 has finished recently, while the other two reactors are still being built — even though the original schedule called for the plant to become operational by 2017. Once completed, the four reactors, which are using South Korean technology, should produce 5.6 gigawatts of electricity and supply up to 25% of the UAE’s electricity needs.
Official figures from Brazil have shown a big increase in the number of fires in the Amazon region in July compared with the same month last year. Satellite images compiled by Brazil’s National Space Agency revealed there were 6,803 – a rise of 28%. President Jair Bolsonaro has encouraged agricultural and mining activities in the Amazon. But under pressure from international investors in early July his government banned starting fires in the region. The latest figures raise concerns about a repeat of the huge wildfires that shocked the world in August and September last year.
