"Paul, can we have some dialing music?" David Letterman would ask, and his bandleader would twinkle a melody on the keyboard as the host plopped a rotary phone on his desk and began calling whomever: CBS chief Les Moonves; an office drone named Meg in a building across the street; his mom, Dorothy, in her kitchen in Indiana. In the span of one hour, he could ask for dialing music and then commission the destruction of an automobile by dropping bowling balls off the Ed Sullivan Theater. Markoe, a writer...

If Trump is so pro-Israel, why are Israelis nervous about his upcoming visit?

Next time on Global Ethics Forum, best-selling author Yuval Noah Harari discusses the ethical implications of the next phase of human development. In this excerpt, Harari explains how new technologies and intelligent design will have unintended consequences.

Er flüstert mir irgendwas ins Ohr, aber ich hab KEIN VERDAMMTES WORT verstanden.

This week we have stories on blocking dangerous or annoying distractions in augmented reality, gene therapy applied with ultrasound to heal bone breaks, and giving robots geckolike gripping power with Online News Editor David Grimm. Deputy News Editor Elizabeth Culotta joins Sarah Crespi to discuss a special package on human migrations—from the ancient origins of Europeans to the restless and wandering scientists of today.

What do Trump and the Saudis have in common? Can Americans who oppose intervention hope for much out of this international trip? Emma Ashford comments.

Give your daily routine an organic-over with the help of these certified beauty heroes

In this week's news, we celebrate Andy Murray’s 30th birthday with his finest doubles moments

Chris Cornell, who tragically passed away Wednesday age 52, was one of the greatest rock vocalists (or vocalists, period) ever to pick up a mic. A Robert Plant for the grunge generation, he was named rock’s greatest singer by Guitar World and fourth-best singer in heavy metal history by Hit Parader, and he came in at No. 9 on Rolling Stone’s “Best Lead Singers of All Time” list. Whether fronting Seattle heroes Soundgarden and supergroups Temple of the Dog and Audioslave, or belting out an epic Bond theme with a license to thrill... Читать дальше...

Abstract: To aid in the design of surfaces that prevent icing, a model and computational simulation of impact ice formation at the single droplet scale was implemented. The nucleation of a single supercooled droplet impacting on a substrate, in rime ice conditions, was simulated. Open source computational fluid dynamics (CFD) software was used for the simulation. To aid in the design of surfaces that prevent icing, a model of impact ice formation at the single droplet scale was proposed•No existing... Читать дальше...

Launched in 2016, Tentrr lets users find and book upscale campsites on private land. The company has just announced its first geographical expansion outside the East Coast, with more than 50 campsites in the San Francisco Bay Area in the pipeline.

It should be a joyous, with thousands of Reds getting ready for the Europa League final in Stockholm next week.

BE CAREFUL what you wish for. Traders were bored last week and now they have got some excitement. The US equity market suffered its worst trading day in eight months, falling 1.8%, with banks dropping 4%. The Volatility index, or Vix, which recently dipped below 10, jumped above 15. The dollar has lost most of its gains since Donald Trump was elected in November (see chart).

Abstract: In 2016, the Integrated Medical Model (IMM) v4.0 underwent an extensive external review in preparation for transition to an operational status. In order to insure impartiality of the review process, the Exploration Medical Capabilities Element of NASA's Human Research Program convened the review through the Systems Review Office at NASA Goddard Space Flight Center (GSFC). The review board convened by GSFC consisted of persons from both NASA and academia with expertise in the fields of statist...

Abstract: Significant progress has been made in the research and development of boundary layer ingesting (BLI) propulsors which studies and high fidelity analyses have predicted will have a four percent reduction in fuel burned for large transport class subsonic cruise aircraft. Funded by NASAs Advanced Air Transport Technology (AATT) Project, this work has necessarily comprised the efforts of inlets, turbomachinery, aeromechanics, nozzles, propulsion airframe integration and acoustics technical...

Imagine Puerto Rico, times 50.

What explains the global resurgence of populism and the rise of political actors on the right? And what are the effects on longstanding alliances, international institutions, and accepted norms? Don't miss this lively conversation with Leon Botstein, president of Bard College, and international affairs expert Walter Russell Mead.

Abstract: There is increasing evidence that a large fraction of asteroids, and even Phobos, have such low densities (

Abstract: Full seven-equation Reynolds stress turbulence models are a relatively new and promising tool for todays aerospace technology challenges. This paper uses two stress-omega full Reynolds stress models to evaluate challenging flows including shock-wave boundary layer interactions, separation and mixing layers. The Wilcox and the SSG/LRR full second-moment Reynolds stress models have been implemented into the FUN3D (Fully Unstructured Navier-Stokes Three Dimensional) unstructured Navier-Stokes...

Abstract: This investigation pertains to distributed propulsion system. Basically, the jet exhaust is divided and channeled through multiple compartments or septa. In one version of the concept each septum is to be driven by an electric fan, the power being supplied by engines suitably mounted on the airframe. In the latter hybrid case the need for heavy power trains is eliminated and system studies indicate a net benefit in efficiency. From aeroacoustics point of view, however, there are concerns.

Abstract: The SCaN Testbed is an advanced integrated communications system and laboratory facility installed on the International Space Station (ISS) in 2012. The testbed incorporates a set of new generation of Software Defined Radio (SDR) technologies intended to allow researchers to develop, test, and demonstrate new communications, networking, and navigation capabilities in the actual environment of space. Qascom, in cooperation with ESA and NASA, is designing a Software Defined Radio GalileoGPS... Читать дальше...
