Scott Morrison will unveil $748m in new cyber security initiatives, with the planned reallocation of resources from within the defence portfolio rising to $1.35bn over a decade once the government unveils a new cyber security strategy in coming months.

Resources reallocated from defence portfolio are planned to rise to $1.35bn over a decade with 500 new jobs created.

Elon is unique.

At age 17, Elon Musk left his home in South Africa and moved to Canada, where he enrolled at Queen’s University in Kingston, Ontario. During his freshman-year in the fall of 1990, Musk befriended Navaid Farooq while living in the same dorm, according to the book “Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future,” by Ashlee Vance.

Farooq, a Canadian who grew up in Geneva, bonded with Musk over their backgrounds abroad and their interest in strategy games, according to the book. Living in such close quarters, Farooq learned a lot about Musk, including what Farooq sees as his defining trait.

Bio-Wall forms a temporary flexible film over the mucosa of the nose, throat and oral cavity. Antiviral components in the bio-adhesive matrix are meant to trap the virus and block it.

“Once Bio-Wall is sprayed over the mucosa, it masks the tissue from pathogen penetration and infectious disease such as the Covid-19 virus” for several hours, says BioChange Chairman and CEO Ishay Attar.

A nasal spray in development and a surface-disinfecting spray already on the market are intended to keep us safe from virus particles in the air.

Shutting the window is usually the last resort in mitigating environmental noise, at the expense of natural ventilation. We describe an active sound control system fitted onto the opening of the domestic window that attenuates the incident sound, achieving a global reduction in the room interior while maintaining natural ventilation. The incident sound is actively attenuated by an array of control modules (a small loudspeaker) distributed optimally across the aperture. A single reference microphone provides advance information for the controller to compute the anti-noise signal input to the loudspeakers in real-time. A numerical analysis revealed that the maximum active attenuation potential outperforms the perfect acoustic insulation provided by a fully shut single-glazed window in ideal conditions. To determine the real-world performance of such an active control system, an experimental system is realized in the aperture of a full-sized window installed on a mockup room. Up to 10-dB reduction in energy-averaged sound pressure level was achieved by the active control system in the presence of a recorded real-world broadband noise. However, attenuation in the low-frequency range and its maximum power output is limited by the size of the loudspeakers.

Evidence of SARS-CoV-2 transmission from mother to fetus 😢.

SARS-CoV-2 outbreak is the first pandemic of the century. SARS-CoV-2 infection is transmitted through droplets; other transmission routes are hypothesized but not confirmed. So far, it is unclear whether and how SARS-CoV-2 can be transmitted from the mother to the fetus. We demonstrate the transplacental transmission of SARS-CoV-2 in a neonate born to a mother infected in the last trimester and presenting with neurological compromise. The transmission is confirmed by comprehensive virological and pathological investigations. In detail, SARS-CoV-2 causes: maternal viremia, placental infection demonstrated by immunohistochemistry and very high viral load; placental inflammation, as shown by histological examination and immunohistochemistry, and neonatal viremia following placental infection. The neonate is studied clinically, through imaging, and followed up. The neonate presented with neurological manifestations, similar to those described in adult patients.

A short gamma ray burst left the most-distant optical afterglow ever detected –incredibly faint and fast signals sometimes lasting mere hours–some 10 billion light years away, 3.8 billion years after the Big Bang. Astronomers suspect that up to one-third of all short gamma ray bursts come from merging neutron stars in globular clusters of old stars blinding whole galaxies with light and destroying millions of worlds. Known as SGRB181123B, it is the second most-distant well-established SGRB ever detected and the most distant event with an optical afterglow.

The appearance of an SGRB at such an early time, report astronomers at the Keck Observatory and Northwestern University could alter theories about their origins, particularly the length of time it takes two neutron stars to merge and produce these powerful explosions, as well as the rate of neutron star mergers in the young universe.

“This was a very exciting object to study,” said Kerry Paterson, a postdoctoral associate at Northwestern University’s Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) and lead author of the study. “Our research now suggests neutron star mergers could occur surprisingly quickly for some systems — with neutron star binaries spiraling together in less than a billion years to create an SGRB.”

It turns out the moon is a little younger than scientists previously thought — about 85 million years younger, to be precise.

The PLA Navy may be poised to overcome a technological and tactical defect that has plagued it since its founding.

By James Holmes

Here’s What You Need To Remember: American submariners long lampooned Soviet and Chinese nuclear boats for being noisy and easy to detect. PLA Navy boats remained backward long after the Cold War. Ultraquiet propulsion, though, would put an end to unquestioned U.S. acoustic supremacy, opening up new operational and strategic vistas before the PLA Navy while ushering in a deadlier phase of U.S.-China strategic competition.
