[Matt] from [DIY Perks] has made a name for himself building nice custom computing machines, and his latest triple-monitor luggable PC (video after the break) is sure to give most high-performance desktop machines a run for their money.

The large central monitor folding laptop monitors mounted vertically on either size look impressive, but only just scratches the surface of this build. Hidden behind aluminum panels are Ryzen 5950X CPU and RTX 3,080 GPU with water cooling, 64 GB of RAM, and two 8 TB SSDs. A set of high-quality speaker drivers, subwoofer, and audio amps is also included. All this hardware pulls about 600 W of power from a large DC-DC converter block, which in turn receives power from either a pair of onboard AC-DC converters or a 16 V – 63 V DC source, like a battery system.

To mount everything to the back of the main monitor, [Matt] created 3D printed adaptor blocks with threaded inserts which slide under existing hooks on the back of the monitor. Aluminum angles screw to these blocks to cover the edges of the display panel, together with a large mounting plate with pre-drilled holes to mount all the components on standoffs. A set of adjustable and removable legs mount to the side of the PC. A hinged door in the back cover allows storage space for a keyboard and mouse during transport. When folded, the laptop monitors don’t fully cover the main monitor, so [Matt] created a leather cover that doubles as a cable and accessory organizer.

MASK Architects has designed the world’s first steel 3D printed structure of modular houses for Nivola Museum’s visitors, Tourists and Artists in Orani, city of Sardinia. Öznur Pınar Cer and Danilo Petta have Inspired from the work of “Costantino Nivola”, they have designed “Exosteel Mother Nature” modular houses which they have taken inspiration from him sculpture called the “La Madre”.

The studio is the first architecture and design studio in the world to use a steel 3D-printed “exoskeleton” construction system that supports and distributes all the functional elements of the building, using their new solution of construction technique which they called “EXOSTEEL”.

The house is composed firstly by a hollow central column inserted for one / third of its length into the ground and by various organic branches that support the three floors of the building. On each floor a perimeter frame divides and supports the facades made up of panels modeled to follow the organic shape of the house.

Only two new coronaviruses have spread globally the past 2 decades: SARS-CoV, which caused an outbreak of severe acute respiratory syndrome (SARS) in 2,003 and SARS-CoV-2, the virus that causes COVID-19. But that may just be the tip of the iceberg of undetected infections with related viruses emerging from bats, a new paper claims. In a preprint published yesterday researchers estimate that an average of 400,000 people are likely infected with SARS-related coronaviruses every year, in spillovers that never grow into detectable outbreaks.

The researchers, including Peter Daszak from the EcoHealth Alliance and Linfa Wang from Duke-NUS Medical School in Singapore, created a detailed map of the habitats of 23 bat species known to harbor SARS-related coronaviruses, the group to which SARS-CoV and SARS-CoV-2 belong, and then overlaid it with data on where humans live to create a map of potential infection hot spots. They found that close to 500 million people live in areas where spillovers can occur, including northern India, Nepal, Myanmar, and most of Southeast Asia. The risk is highest in southern China, Vietnam, Cambodia, and on Java and other islands in Indonesia (see map, below).

Study pinpoints Asian regions that could spark the next coronavirus pandemic.

A new Rutgers study will examine how COVID-19 is affecting individuals in a number of cognitive-related areas, including memory loss, “brain fog,” and dementia.

“Many people who recover from mild or moderate COVID-19 notice slowed thinking or memory loss, and this motivated us to leverage our experience in studying cognitive issues related to Alzheimer’s disease, multiple sclerosis, and HIV to examine this phenomenon,” said Dr. William T. Hu, associate professor and chief of cognitive neurology at Rutgers Robert Wood Johnson Medical School and the Institute for Health, Health Care Policy, and Aging Research.

A leading cognitive neurologist and neuroscientist, Dr. Hu is spearheading the characterization of cognitive impairment following mild-to-moderate COVID-19 at Rutgers.

In semiconductor device applications, there is an increasing demand for semiconductors with very high carrier concentrations. The semiconductor material parameters, namely carrier density and mobility, primarily determine device performance. Hence, it is important to accurately characterize the carrier density and mobility of a semiconductor for the development of its device applications.

The use of THz waves, or with wavelengths of around 300 µm and frequency of about 1 THz, in the nondestructive testing of semiconductors has been continuously expanding. Free carriers in a material absorb THz radiation, which makes it possible to estimate the electrical properties of semiconductors using THz waves.

Researchers at Osaka University, in collaboration with Nippo Precision Co., Ltd., developed a THz time-domain ellipsometry system (Tera Evaluator) that extends the range of carrier concentrations measurable by THz waves up to ~1020 cm-3 and potentially higher by improving the precision of said optical technique. In THz time-domain ellipsometry, linearly polarized THz pulses are incident on a sample and the electric field strength of the reflected THz waves as a function of time is measured. Specifically, the reflected waves polarized in the direction parallel ℗ and perpendicular (s) to the plane of incidence are of interest. The ratio of the p-and s-polarization components yields information on the electric permittivity of the sample, allowing for the evaluation of the carrier density and mobility. As such, unlike THz time-domain spectroscopy, THz time-domain ellipsometry does not require reference measurements through an aperture or standard mirror.

According to researchers from the Singapore University of Technology and Design (SUTD), a recently discovered family of two-dimensional (2D) semiconductors could pave the way for high-performance and energy-efficient electronics. Their findings, published in npj 2D Materials and Applications, may lead to the fabrication of semiconductor devices applicable in mainstream electronics and optoelectronics—and even potentially replace silicon-based device technology altogether.

In the quest of miniaturizing electronic devices, one well-known trend is Moore’s law, which describes how the number of components in the integrated circuits of computers doubles every two years. This trend is possible thanks to the ever-decreasing size of transistors, some of which are so small that millions of them can be crammed onto a chip the size of a fingernail. But as this trend continues, engineers are starting to grapple with the inherent material limitations of silicon-based device technology.

“Due to the quantum tunneling effect, shrinking a silicon-based transistor too small will lead to highly uncontrollable device behaviors,” said SUTD Assistant Professor Ang Yee Sin, who led the study. “People are now looking for new materials beyond the ‘silicon era’, and 2D semiconductors are a promising candidate.”

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern threatens the efficacy of existing vaccines and therapeutic antibodies and underscores the need for additional antibody-based tools that potently neutralize variants by targeting multiple sites of the spike protein. We isolated 216 monoclonal antibodies targeting SARS-CoV-2 from plasmablasts and memory B cells collected from patients with coronavirus disease 2019. The three most potent antibodies targeted distinct regions of the receptor-binding domain (RBD), and all three neutralized the SARS-CoV-2 Alpha and Beta variants. The crystal structure of the most potent antibody, CV503, revealed that it binds to the ridge region of SARS-CoV-2 RBD, competes with the angiotensin converting enzyme 2 receptor, and has limited contact with key variant residues K417, E484 and N501. We designed bispecific antibodies by combining non-overlapping specificities and identified five bispecific antibodies that inhibit SARS-CoV-2 infection at concentrations of less than 1 ng/mL. Through a distinct mode of action, three bispecific antibodies cross-linked adjacent spike proteins using dual N-terminal domain-RBD specificities. One bispecific antibody was greater than 100-fold more potent than a cocktail of its parent monoclonals in vitro and prevented clinical disease in a hamster model at a 2.5 mg/kg dose. Notably, two bispecific antibodies in our panel comparably neutralized the Alpha, Beta, Gamma and Delta variants and wild-type virus. Furthermore, a bispecific antibody that neutralized the Beta variant protected hamsters against SARS-CoV-2 expressing the E484K mutation. Thus, bispecific antibodies represent a promising next-generation countermeasure against SARS-CoV-2 variants of concern.

An army of drones descending over a city from a massive corporate airship…damn, amazon just out-cyberpunked cyberpunk itself.

While the origin of this video has something, in part, to do with April Fool’s day, there’s some truth to this concept too. Amazon has, for long, been experimenting with aerial deliveries, sending unmanned drones to fulfill package deliveries. In fact, the blimp idea isn’t completely far-fetched, either.
