Public health officials have confirmed the first U.S. case of a mysterious coronavirus that has sickened hundreds of people in China, the Centers for Disease Control and Prevention said Tuesday.

A Snohomish County, Washington State resident who was returning from China on Jan. 15 was diagnosed with the Wuhan coronavirus, according to the CDC.

Officials said the patient, a male in his 30s, is “very healthy.” He is currently being isolated at a medical center in the state “out of caution” and “poses little risk” to the public, they said. The CDC said the man reached out to local health authorities last week once he started experiencing pneumonia-like symptoms.

SAN FRANCISCO, Jan. 21, 2020 /PRNewswire/ — Capella Space, an information services company providing Earth observation data on demand, today unveiled its evolved satellite design to enable on-demand observations of anywhere on Earth. Informed by extensive customer feedback and findings from the launch of Denali, Capella’s testbed satellite, the re-engineered design features a suite of technological innovations to deliver timely, flexible and frequent sub-0.5 meter very high quality images to the market. The enhanced technology package will deliver the most advanced offering for small satellite SAR imagery on the market.

This year marks the Eighth Review Conference (RevCon) of the Biological Toxins and Weapons Convention (BWC). At the same time, ongoing international efforts to further and more deeply investigate the brain’s complex neuronal circuitry are creating unprecedented capabilities to both understand and control neurological processes of thought, emotion, and behavior. These advances have tremendous promise for human health, but the potential for their misuse has also been noted, with most discussions centering on research and development of agents that are addressed by existing BWC and Chemical Weapons Convention (CWC) proscriptions. In this article, we discuss the dual-use possibilities fostered by employing emergent biotechnologic techniques and tools—specifically, novel gene editors like clustered regular interspaced short palindromic repeats (CRISPR)—to produce neuroweapons. Based on our analyses, we posit the strong likelihood that development of genetically modified or created neurotropic substances will advance apace with other gene-based therapeutics, and we assert that this represents a novel—and realizable—path to creating potential neuroweapons. In light of this, we propose that it will be important to re-address current categorizations of weaponizable tools and substances, so as to better inform and generate tractable policy to enable improved surveillance and governance of novel neuroweapons.

T his year marks the Eighth Review Conference (RevCon) of the Biological Toxins and Weapons Convention (BWC), the purpose of which is to ensure that the convened parties’ directives continue to be relevant to and viable for prohibiting the development, production, and stockpiling of biological weapons in the face of newly emerging scientific advancements and biotechnologies. Apropos of issues raised at previous RevCons and elsewhere, there are growing concerns about current and future weaponization of neurobiological agents and tools (ie, “neuroweapons”^1–6).

When you throw something into a black hole, its information seems to disappear. This may be a hint that black holes, as well as our entire universe, is 2-dimensional.

Scientists have long assumed that fungi exist mainly to decompose matter into chemicals that other organisms can then use. But researchers at the Albert Einstein College of Medicine of Yeshiva University have found evidence that fungi possess a previously undiscovered talent with profound implications: the ability to use radioactivity as an energy source for making food and spurring their growth.

“The fungal kingdom comprises more species than any other plant or animal kingdom, so finding that they’re making food in addition to breaking it down means that Earth’s energetics—in particular, the amount of radiation energy being converted to biological energy—may need to be recalculated,” says Dr. Arturo Casadevall, chair of microbiology & immunology at Einstein and senior author of the study, published May 23 in PLoS ONE.

The ability of fungi to live off radiation could also prove useful to people: “Since ionizing radiation is prevalent in outer space, astronauts might be able to rely on fungi as an inexhaustible food source on long missions or for colonizing other planets,” says Dr. Ekaterina Dadachova, associate professor of nuclear medicine and microbiology & immunology at Einstein and lead author of the study.

Circa 2007

The first rotational laser-driven motor has been demonstrated by Japanese researchers – it could have novel medical and scientific uses.

Circa 2019

A gamma-ray burst registered in December of 2017 turns out to be “one of the closets GRBs ever observed”. The discovery is featured in Nature – and it has yielded valuable information about the formation of the most luminous phenomenon in the universe. Scientists from the Niels Bohr Institute at the University of Copenhagen helped carrying out the analysis.

Jonatan Selsing frequently receives text messages from a certain sender regarding events in space. It happens all around the clock, and when his cell phone goes ‘beep’ he knows that yet another gamma-ray burst (GRB) notification has arrived. Which, routinely, raises the question: Does this information — originating from the death of a massive star way back, millions if not billions of years ago – merit further investigation?

Devices made with 2D semiconductors might start to appear sooner than you expected.

If there’s one thing about Moore’s Law that’s obvious to anyone, it’s that transistors have been made smaller and smaller as the years went on. Scientists and engineers have taken that trend to an almost absurd limit during the past decade, creating devices that are made of one-atom-thick layers of material.

The most famous of these materials is, of course, graphene, a hexagonal honeycomb-shaped sheet of carbon with outstanding conductivity for both heat and electricity, odd optical abilities, and incredible mechanical strength. But as a substance with which to make transistors, graphene hasn’t really delivered. With no natural bandgap—the property that makes a semiconductor a semiconductor—it’s just not built for the job.

Instead, scientists and engineers have been exploring the universe of transition metal dichalcogenides, which all have the chemical formula MX2. These are made up of one of more than a dozen transition metals (M) along with one of the three chalcogenides (X): sulfur, selenium, or tellurium. Tungsten disulfide, molybdenum diselenide, and a few others can be made in single-atom layers that (unlike graphene) are natural semiconductors. These materials offer the enticing prospect that we will be able to scale down transistors all the way to atom-thin components long after today’s silicon technology has run its course.

Retinal scanning could be a huge leap forward. Even in rich countries, 50% to 80% of Alzheimer’s cases go undiagnosed.
