Wikipedia: “With Folded Hands…” is a 1947 science fiction novelette by American writer Jack Williamson. Willamson’s influence for this story was the aftermath of World War II and the atomic bombing of Hiroshima and Nagasaki and his concern that “some of the technological creations we had developed with the best intentions might have disastrous consequences in the long run.”

The novelette, which first appeared in the July 1947 issue of Astounding Science Fiction, was included in The Science Fiction Hall of Fame, Volume Two (1973) after being voted one of the best novellas up to 1965. It was the first of several Astounding stories adapted for NBC’s radio series Dimension X.

New “exascale” supercomputers will bring breakthroughs in science. But the technology also exists to study nuclear weapons.

In recent years, cloud computing has proven itself as one of the fundamental technologies empowering modern enterprises with on-demand connectivity. Without it, the widespread move toward hybrid work wouldn’t have been possible during the COVID–19 pandemic. Yet what about cybersecurity in this new cloud-centric world?

The convenience of instant connectivity has created new vulnerabilities for security teams to confront, and many organizations are still playing catchup, with 81% of organizations experiencing cloud-related security incidents in the past year.

H5N1 avian flu has existed for a quarter century. Only rarely have human cases occurred, with no sustained transmission reported. But “we cannot assume that will remain the case,” WHO Director General Tedros Adhanom Ghebreyesus said at a news conference. New, frequent reports that the disease has crossed into small mammals like minks, otters, foxes, and sea lions are cause for alarm, given the species’ similarities with humans, he noted.

While the risk to people remains low, public health officials must prepare “to face outbreaks in humans, and be ready also to control them as soon as possible,” Dr. Sylvie Briand, director of Global Infectious Hazard Preparedness and Emergency Preparedness at the WHO, told Fortune.

Ghebreyesus cautioned against touching or collecting sick or dead animals, and encouraged those who encounter such to report them to local authorities. Countries must strengthen their avian flu surveillance in areas where humans and wild animals interact, he insisted. And public health officials must work with manufacturers to ensure that vaccines and antivirals are available for global use, he said.

Bias in juries pose a serious challenge for judges and attorneys to conduct fair, equal and impartial trials. A recent paper published in Social Cognitive and Affective Neuroscience considers the overlap between social cognitive processes such as cultural and racial stereotyping and brain activity associated with bias against defendants accused of severe crimes.

R. McKell Carter, one of the paper’s co-authors, is an assistant professor of psychology and neuroscience at the University of Colorado Boulder. He is an expert on social cognition: the processes of the brain that interpret the actions, intentions and expectations of others.

Carter’s study examines the role of social cognition in crime-type bias, when jurors perceive the prosecutor’s case stronger based on the severity of the charges against the defendant. Using functional magnetic resonance imaging (fMRI) scans on mock jurors, researchers mapped out regions of the brain that activated when jurors were presented with fictional case narratives and evidence.

Scientists from the Tsukuba Research Center for Energy Materials Science at the University of Tsukuba demonstrated a simple method to produce ionic liquid microdroplets that work as flexible, long-lasting, and pneumatically tunable lasers. Unlike existing “droplet lasers” that cannot operate under atmosphere, this new development may enable lasers that can be used in everyday settings.

Lotus plants are prized for their beauty, and have a remarkable self-cleaning property. Instead of flattening on the surface of a lotus leaf, water droplets will form near-perfect spheres and roll off, taking dust with them. This “lotus effect” is caused by microscopic bumps in the leaf. Now, a team of researchers at the University of Tsukuba have taken advantage of an artificial lotus effect to create liquid droplets that can act like lasers, while remaining stable for up to a month. Currently available “droplet lasers” cannot be used under ambient conditions, since they will simply evaporate unless enclosed inside a container.

In this new research, an ionic liquid called 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF₄) was mixed with a dye that allows it to become a laser. This liquid was chosen because it evaporates very slowly and has a relatively large surface tension. Then, a quartz substrate is coated with tiny fluorinated silica nanoparticles to make the surface repel liquids. When the EMIBF₄ is deposited on it from a pipette, the tiny droplets remain almost completely spherical. The researchers showed that the droplet could remain stable for 30 days at least.
