What I find particularly seductive about Google Street View is that it purports to be a very objective document of our world. It is simply the product of a car (or a motorbike or a hiker) driving down a street taking pictures. But, of course, it is far from an objective document. Humans get in the way, as they always do, filling each scene with stories.
There is something tantalizing about being there but not being there, about being everywhere and nowhere at once. The geospatial distance leaves us wanting, hungry for more. I’m enamored with the glitchiness of these human landscapes, the way people’s legs are sometimes separated from their bodies, the way everyone’s faces are blurred out, as if they no longer exist (sometimes they no longer do). This is our world, but it is not our world.
When your heart beats faster than usual, it can mean that you’re coming down with a cold, flu, coronavirus, or other viral infection. That’s the conclusion of recent medical research.
So wearable devices that measure your resting heart rate—made by Apple, Fitbit, Garmin, and others—might help scientists spot viral outbreaks, and also give you more insight into your own health.
Scripps Research designed DETECT (Digital Engagement & Tracking for Early Control & Treatment), a study that will monitor your heart rate and allow you to record symptoms like fever or coughing.
Researchers have developed an ultra-fast electrical switch that they hope can be used in communication and imaging applications.

The race is on to find a vaccine against the new COVID-19 coronavirus. Professor Jonathan Heeney explains why a cautious approach is needed and how his team is using new technology developed for influenza and Ebola viruses to target the new infection.
It is hard now to conceive that two months ago, few people had heard of the new coronavirus. Now, the virus, which causes the disease COVID-19, has spread to every corner of the globe. The World Health Organization has officially declared the outbreak a pandemic.
With the threat of hundreds of thousands – possibly millions – of people being infected and healthcare systems becoming overwhelmed, the race is on to develop a vaccine that will protect individuals and slow the spread of the disease. But Professor Jonathan Heeney, Head of the Laboratory of Viral Zoonotics at the University of Cambridge, and one of the people working on a vaccine, says that coronaviruses present a particular challenge to vaccine developers.
Coronaviruses are named after their appearance: they are spherical objects, on the surface of which sit ‘spike’ proteins. The virus uses these spikes to attach to and invade cells in our body. Once inside, the virus uses the cell’s own machinery to help itself replicate and spread throughout the body, causing disease and allowing it to transmit onwards.
Traditionally, scientists would develop vaccines that programme the body to produce antibodies that recognise and block these spikes. But this strategy can misfire with coronaviruses due to a phenomenon known as ‘antibody-induced enhancement’ or ‘vaccine-induced enhancement’, says Heeney.
“If you make antibodies against the spike, they can end up binding to it and helping the virus invade important immune cells known as monocyte-macrophages. Rather than destroying the virus, these cells can then end up being reprogrammed by the viruses, exacerbating the immune response and making the disease much, much worse than it would otherwise be.”
Insta Novels launched August 22, 2018 on the Library’s Instagram account (@nypl) with Part 1 of a newly digitized version of Alice’s Adventures in Wonderland by Lewis Carroll. The novel is illustrated by well-known designer Magoz (@magoz).
First, go to the Library’s Instagram account (@nypl) and tap Part 1 of Alice’s Adventures in Wonderland in the Highlights section, right under the bio.
Rest your thumb on lower right part of the screen to hold the page, and lift your thumb to turn the page. (The lower right thumb holder is designed to double as a flip book: if you lift your thumb and let the pages flip, you’ll see an animation.)

See the first laboratory on Earth – Blombos Cave. Here our ancestors conducted the first chemistry experiments.
Blombos Cave is an archaeological site located in Blomboschfontein Nature Reserve, about 300 km east of Cape Town on the Southern Cape coastline, South Africa. The cave contains Middle Stone Age (MSA) deposits currently dated at between c. 100,000 and 70,000 years Before Present (BP), and a Late Stone Age sequence dated at between 2000 and 300 years BP. The cave site was first excavated in 1991 and field work has been conducted there on a regular basis since 1997, and is ongoing.
The excavations at Blombos Cave have yielded important new information on the behavioural evolution of anatomically modern humans. The archaeological record from this cave site has been central in the ongoing debate on the cognitive and cultural origin of early humans and to the current understanding of when and where key behavioural innovations emerged among Homo sapiens in southern Africa during the Late Pleistocene. Archaeological material and faunal remains recovered from the Middle Stone Age phase in Blombos Cave – dated to ca. 100,000–70,000 years BP – are considered to represent greater ecological niche adaptation, a more diverse set of subsistence and procurements strategies, adoption of multi-step technology and manufacture of composite tools, stylistic elaboration, increased economic and social organisation and occurrence of symbolically mediated behaviour.
The most informative archaeological material from Blombos Cave includes engraved ochre, engraved bone ochre processing kits, marine shell beads, refined bone and stone tools and a broad range of terrestrial and marine faunal remains, including shellfish, birds, tortoise and ostrich egg shell and mammals of various sizes.[20][21][22] These findings, together with subsequent re-analysis and excavation of other Middle Stone Age sites in southern Africa, have resulted in a paradigm shift with regard to the understanding of the timing and location of the development of modern human behaviour.
From a New England Journal of Medicine article (March 11, 2020):
A central strategy for health care surge control is “forward triage” — the sorting of patients before they arrive in the emergency department (ED). Direct-to-consumer (or on-demand) telemedicine, a 21st-century approach to forward triage that allows patients to be efficiently screened, is both patient-centered and conducive to self-quarantine, and it protects patients, clinicians, and the community from exposure.
It can allow physicians and patients to communicate 24/7, using smartphones or webcam-enabled computers. Respiratory symptoms — which may be early signs of Covid-19 — are among the conditions most commonly evaluated with this approach. Health care providers can easily obtain detailed travel and exposure histories. Automated screening algorithms can be built into the intake process, and local epidemiologic information can be used to standardize screening and practice patterns across providers.
More than 50 U.S. health systems already have such programs. Jefferson Health, Mount Sinai, Kaiser Permanente, Cleveland Clinic, and Providence, for example, all leverage telehealth technology to allow clinicians to see patients who are at home. Systems lacking such programs can outsource similar services to physicians and support staff provided by Teladoc Health or American Well. At present, the major barrier to large-scale telemedical screening for SARS-CoV-2, the novel coronavirus causing Covid-19, is coordination of testing. As the availability of testing sites expands, local systems that can test appropriate patients while minimizing exposure — using dedicated office space, tents, or in-car testing — will need to be developed and integrated into telemedicine workflows.
Excerpts from a New York Times article (Feb 28, 2020):
“Life begins at 55, the age at which I published my first book,” he wrote in “From Eros to Gaia,” one of the collections of his writings that appeared while he was a professor of physics at the Institute for Advanced Study — an august position for someone who finished school without a Ph.D. The lack of a doctorate was a badge of honor, he said. With his slew of honorary degrees and a fellowship in the Royal Society, people called him Dr. Dyson anyway.
Freeman J. Dyson, a mathematical prodigy who left his mark on subatomic physics before turning to messier subjects like Earth’s environmental future and the morality of war, died on Friday at a hospital near Princeton, N.J. He was 96.
As a young graduate student at Cornell University in 1949, Dr. Dyson wrote a landmark paper — worthy, some colleagues thought, of a Nobel Prize — that deepened the understanding of how light interacts with matter to produce the palpable world. The theory the paper advanced, called quantum electrodynamics, or QED, ranks among the great achievements of modern science.
