FAI Considers Lowering Boundary of Space
Posted by Genevieve Klien in category: space travel
Well, there’s some great news for Virgin Galactic as it prepares for an attempt to send SpaceShipTwo to space. The Fédération Aéronautique Internationale (FAI), which maintains records for aviation and spaceflight, is considering lowering the boundary of space from 100 to 80 km (62.1 to 47.7 miles).
Virgin Galactic’s SpaceShipTwo probably can’t reach the 100 km boundary, which is also known as the Karman line.
FAI issued the following statement last week:

Henri Becquerel and the Serendipitous Discovery of Radioactivity
Posted by Genevieve Klien in categories: education, engineering, particle physics, transportation
Antoine Henri Becquerel (born December 15, 1852 in Paris, France), known as Henri Becquerel, was a French physicist who discovered radioactivity, a process in which an atomic nucleus emits particles because it is unstable. He won the 1903 Nobel Prize in Physics with Pierre and Marie Curie, the latter of whom was Becquerel’s graduate student. The SI unit for radioactivity called the becquerel (or Bq), which measures the amount of ionizing radiation that is released when an atom experiences radioactive decay, is also named after Becquerel.
Becquerel was born December 15, 1852 in Paris, France, to Alexandre-Edmond Becquerel and Aurelie Quenard. At an early age, Becquerel attended the preparatory school Lycée Louis-le-Grand, located in Paris. In 1872, Becquerel began attending the École Polytechnique and in 1874 the École des Ponts et Chaussées (Bridges and Highways School), where he studied civil engineering.

CRISPR has many promising applications—but the gene-edited twins represent something more troubling
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, genetics
Last week Chinese researchers rocked the world with reports that twin babies whose genes the scientists’ edited prior to birth had been born, the product of secret experiments that are being widely decried as unethical. Even as that story plays out, it is true that CRISPR gene editing is already being used in humans, in ways that illustrate just how unethical this recent use was.
“Patients’ parents have been emailing me a lot,” says Hye Young Lee, a researcher at the University of Texas San Antonio whose work looks at alternative delivery methods for CRISPR. Lee says she normally gets a few emails a month from the parents of the patients she works with, but that the number of emails went up recently—in relation, she suspects, to the news of the CRISPR babies, which is creating the illusion that CRISPR and other gene editing techniques are ready for extensive use in humans.
The scientific community’s current consensus is that they’re far from being at that stage—and it’s impossible to know now when or if they will be. But gene editing is being used in adult humans, to early trials to treat genetic diseases. In terms of gene editing for adults, “I know that there are things going on,” Lee says, but it’s nothing like this week’s news. Although her own work is at least a few years away from being ready for human testing, there are some cautiously progressing trials at drug companies using CRISPR in adult humans who have diseases that are the result on mutations in a single gene.

Research explores the ethical implications of creating sentient and self-aware sexbots
Posted by Amberley Levine in categories: robotics/AI, sex
So far, robots have primarily been developed to fulfill utilitarian purposes, assisting humans or serving as tools to facilitate the completion of particular tasks. As robots become more human-like, however, this could pose significant challenges, particularly for robots built to engage with humans socially.
Humans have used sex dolls as inanimate objects for sexual pleasure throughout history. Animated sex robots, social robots created to meet humans’ needs for sex and affection, offer more. Due to recent developments in robotics and AI, sex robots are now becoming more advanced and human-like. Purchasers can have them customised both in appearance and in how they speak and behave to simulate intimacy, warmth and emotion.
Currently, sex robots are inanimate things, able to simulate but not engage in mutual intimacies. In the future, however, technological advances might allow researchers to manufacture sentient, self-aware sex robots with feelings, or sexbots. The implications of the availability of sexbots as customisable perfect partners for intimate relationships with humans are potentially vast.
The discovery of brain structures that apparently mark time has raised a larger question: What is time, anyway?
