Radio observations of a cold, dense cloud of molecular gas reveal more than a dozen unexpected molecules.

Scientists have discovered a vast, previously unknown reservoir of new aromatic material in a cold, dark molecular cloud by detecting individual polycyclic aromatic hydrocarbon molecules in the interstellar medium for the first time, and in doing so are beginning to answer a three-decades-old scientific mystery: how and where are these molecules formed in space?

“We had always thought polycyclic aromatic hydrocarbons were primarily formed in the atmospheres of dying stars,” said Brett McGuire, Assistant Professor of Chemistry at the Massachusetts Institute of Technology, and the Project Principal Investigator for GOTHAM, or Green Bank Telescope (GBT) Observations of TMC-1: Hunting Aromatic Molecules. “In this study, we found them in cold, dark clouds where stars haven’t even started forming yet.”

High-precision delivery of microrobots at the whole-body scale is of considerable importance for efforts toward targeted therapeutic intervention. However, vision-based control of microrobots, to deep and narrow spaces inside the body, remains a challenge. Here, we report a soft and resilient magnetic cell microrobot with high biocompatibility that can interface with the human body and adapt to the complex surroundings while navigating inside the body. We achieve time-efficient delivery of soft microrobots using an integrated platform called endoscopy-assisted magnetic actuation with dual imaging system (EMADIS).

Robotics researchers are developing exoskeleton legs capable of thinking and making control decisions on their own using artificial intelligence called ExoNet

THE PROBLEM

Current generation of exoskeleton legs need to be manually controlled by users via smartphones or joysticks, It has a problem where motors need to change their operating mode manually when they perform a new activity in different terrains.

A mixed-reality headset Apple is developing will be equipped with more than a dozen cameras for tracking hand movements and showing video of the real world to people wearing it, along with ultra-high-resolution 8K displays and advanced technology for eye tracking, according to a person with direct knowledge of the device.

Those are among a bevy of features Apple is planning for the headset, a device that could represent one of the company’s most ambitious efforts to build a new technology platform. The Information viewed internal Apple images of a late-stage prototype from last year, which show a sleek, curved visor attached to the face by a mesh material and swappable headbands. An artist’s rendering based on the images of the headset and created by The Information appears below.

By 2050, the number of adults over the age of 65 globally will double, reaching a staggering 1.6 billion, with the largest growth in the developing world. This growth will be one of the greatest social, economic, and political transformations of our time, that will impact existing healthcare, government and social systems, that today are largely not inclusive of the ageing population or built to the scale needed to support it.

But we can begin to make investments in our support systems (enabled and scaled by technology) that encompass a coordinated response from governments, society, academia, and the private sector.

A precursor to investing in innovative solutions will be to acknowledge the needs of older adults and identify their caregiving challenges. These are the issues that will inform the solutions agenda.

TL;DR: Last week, we kicked off a three-part series on the future of human-computer interaction (HCI). In the first post, we shared our 10-year vision of a contextually-aware, AI-powered interface for augmented reality (AR) glasses that can use the information you choose to share, to infer what you want to do, when you want to […].

Wiesendanger points out that unlike SARS and MERS, no intermediate host between bats and humans has been found more than a year since the start of the pandemic. Thus far, there is no evidence for the zoonotic theory to explain the outbreak.

Indeed, during the joint China-WHO report issued on Feb. 9, Liang Wannian, head of the Chinese National Health Commission’s Expert Panel of COVID-19 Response, stated that 50000 samples of wild animals from 300 different species (including bats) as well as 11000 farm animals in 31 Chinese provinces — taken between November 2019 and March 2020 — had all tested negative for SARS-CoV-2, the virus which causes COVID-19.

The researcher claimed that the SARS-CoV-2 virus is “astonishingly effective” at binding to human receptor cells (hACE2). He said this is due to its special hACE2 binding domains paired with the furin cleavage sites of the virus’ telltale spike protein.

He stated that this is the first time a coronavirus has exhibited both characteristics and that it points to a “non-natural origin.” Within the betacoronaviruses of sarbecovirus lineage B, the polybasic furin cleavage site is unique to SARS-CoV-2, according to News Medical Life Sciences.
