Remembering life experiences from the visual perspective of an outside observer changes the brain’s functional connectivity and appears to make traumatic memories less intense.
The high demand on medical devices and personal protective equipment (PPE) during the COVID-19 crisis left millions of health care professionals unprotected in the middle of this situation, as governments around the world were not prepared for such pandemic. The three-dimensional printing (3DP) community, from universities to 3DP enthusiasts with printers at home, was there to support hospitals from day 1 on this demand by providing PPE and other medical supplies (e.g., face shields and valves for respiratory machines). This editorial covers the importance of 3DP in the fight against COVID-19 and how this can be used to tackle potential pandemics and support the supply chain.
After a series of cases of pneumonia in Wuhan, the capital city of Hubei province (China), the Chinese health authorities announced in January 2020 that a novel coronavirus, officially known as severe acute respiratory syndrome coronavirus (SARS-CoV)-2, was responsible for these cases.1 SARS-CoV-2, the virus that causes the coronavirus disease (COVID-19), was not detected before the recent pandemic and has been known to be genetically similar to SARS-CoV.1 The COVID-19 is transmitted mainly through contact with an infected individual, through droplets that are produced when the patient coughs or sneezes or through droplets from the saliva or nasal cavity.1,2 To avoid transmission, it is very important to implement individual hygiene measures and especially the use of personal protective equipment (PPE). However, the lack of PPE and other key resources during the COVID-19 crisis has been a constant problem, leaving many health care professionals across the world unprotected.
Dealing with a pandemic, such as COVID-19, is an unprecedented situation in this modern globalized word, which has created extraordinary emergency that is particularly affecting the supply chain.3 The supply chain disruptions, in combination with the enormous needs for medical devices and protective health care material, have created the need of new initiatives and the use of emerging technologies such as three-dimensional printing (3DP) to come forward and support the health care professionals and supply chain.
Scientists are hoping to deliver a vaccine that protects against Covid-19, and its transmission, by early 2021. In order to do that, the development process has been rapidly accelerated.
The world is betting on one thing to stop the pandemic: A vaccine. This is what it will take to bring one to the masses — and the key players behind those efforts.
Israeli hospitals were among the first anywhere to use dexamethasone, a steroid drug, to stop cytokines storms and reduce lung inflammation in severely ill Covid-19 patients. However, steroids can suppress the immune response too strongly.
Additionally, an Israeli hospital is among the first to do a randomized, double-blind, placebo-controlled clinical trial of ivermectin, a drug to treat parasitic infections in people and animals, to see if it can shorten the duration of the disease if given to Covid-19 patients immediately after diagnosis.

A new space tug, only the second-ever to extend the life of older satellites, launched into orbit Saturday on a European rocket after weeks of delays due to weather and rocket checks.
An Arianespace Ariane 5 rocket hefted the Mission Extension Vehicle-2 (MEV-2) into space Sunday (July 31), putting the vehicle en route to an Intelsat satellite waiting for a boost into a higher orbit. Riding along on the rocket were two satellites for broadband communications.
A dust devil, an avalanche, a moon and a crater all made the cut of top Mars Reconnaissance Orbiter images.
Tens of thousands of Google account holders have been warned of state-sponsored attacks targeting them.
Vast lava tubes pock the surface of the moon and Mars, and could protect explorers from the elements. But first someone needs to explore them.
To avoid this problem, the researchers came up with several shortcuts and simplifications that help focus on the most important interactions, making the calculations tractable while still providing a precise enough result to be practically useful.
To test their approach, they put it to work on a 14-qubit IBM quantum computer accessed via the company’s IBM Quantum Experience service. They were able to visualize correlations between all pairs of qubits and even uncovered long-range interactions between qubits that had not been previously detected and will be crucial for creating error-corrected devices.
They also used simulations to show that they could apply the algorithm to a quantum computer as large as 100 qubits without calculations getting intractable. As well as helping to devise error-correction protocols to cancel out the effects of noise, the researchers say their approach could also be used as a diagnostic tool to uncover the microscopic origins of noise.
