The Hero of Little Streetby Gregory Rogers
written for ages 2-7 | recommended
published in 2012 | Roaring Brook Press | 32 pages



This is a favorite because it has a Dutch flavor, and so do I. The story begins with our hero – a little boy with a Charlie Brown-esque look about him – managing to lose a trio of bullies by popping into a museum. And since he's there anyway, the boy decides to take a look. 
After he contemplates some modern art pictures and sculptures he comes across a room full of masterpieces, including Jan van Eyck's Portrait of Giovanni Arnolfini and his Wife. While passing by the piece our hero catches the eye of the Giovanni's little dog, and down he comes, right out of the painting! 
The two of them then dance and jump and chase one another through the museum, until they come across a sheet of music lying on the ground. Where did it come from? Ah, wait! The two of them notice that it must have been dropped by that lady at the piano - that lady in Jan Vermeer's painting Girl at Piano. So in they jump, right into the picture, and return the music to the grateful girl. This leads to some more dancing, accompanied by the girl at her piano, before our hero and his dog head off further and deeper into this painting, opening a door and entering Little Street, Delft in seventeenth century Holland!
To say this is an inventive book doesn't suffice! An art-loving parent could use this to introduce their children to some of the masters, and anyone of Dutch heritage could use it to show what the Netherlands looked like three centuries ago. Young children will love it for the sheer rollicking adventure. It ends with our hero back in modern day, but now equipped by his time-traveling artistic adventure with just the tool he needs to help him with those bullies.

"HPV vaccine is cancer prevention". That is the official word from the US government's leading health body, the Centres for Disease Control and Prevention. Well, the CDC gets a B+ for good will, a C- for accuracy, and a F for truthfulness.  
The vaccine prevents HPV, not cancer. As Carolyn Moynihan argues in today's lead article, "'No' is the best vaccine and there are still people who protect their physical and emotional health in that way." What the CDC knows and should be saying is that promiscuity spreads HPV and makes it more dangerous. So why aren't they campaigning against promiscuity? Your guess is as good as mine. Any suggestions?

NASA's Cassini spacecraft is set to make its first dive through the narrow gap between Saturn and its rings on April 26, 2017. Because that gap is a region no spacecraft has ever explored, Cassini will use its dish-shaped high-gain antenna (13 feet or 4 meters across) as a protective shield while passing through the ring plane. No particles larger than smoke particles are expected, but the precautionary measure is being taken on the first dive. The Cassini team will use data collected by one of the spacecraft’s science instruments (the Radio and Plasma Wave Subsystem, or RPWS) to ascertain the size and density of ring particles in the gap in advance of future dives. As a result of its antenna-forward orientation, the spacecraft will be out of contact with Earth during the dive.
Below is a list of milestones expected to occur during the event, if all goes as planned:
-- 5 p.m. PDT (8 p.m. EDT) on April 25: Cassini is approaching Saturn over the planet’s northern hemisphere in advance of its first of 22 planned dives through the gap between the planet and its rings.
-- 1:34 a.m. PDT (4:34 a.m. EDT) on April 26: As it passes from north to south over Saturn, Cassini begins a 14-minute turn to point its high-gain antenna into the direction of oncoming ring particles. In this orientation, the antenna acts as a protective shield for Cassini’s instruments and engineering systems.
-- 2 a.m. PDT (5 a.m. EDT) on April 26: Cassini crosses the ring plane during its dive between the rings and Saturn. The spacecraft’s science instruments are collecting data, but Cassini is not in contact with Earth at this time.
-- No earlier than around midnight PDT on April 26 (3 a.m. EDT on April 27): Earth has its first opportunity to regain contact with Cassini as the giant, 230-foot (70-meter) Deep Space Network antenna at Goldstone, California, listens for the spacecraft’s radio signal.
-- Likely no earlier than 12:30 a.m. PDT (3:30 a.m. EDT) on April 27: Images are scheduled to become available from the spacecraft.
As Cassini engineers monitor the status of the spacecraft, updates to these milestones will be added at:
Updates will also be posted on social media at:

Building on the ability to sequence DNA in space and previous investigations, Genes in Space-3 is a collaboration to prepare, sequence and identify unknown organisms, entirely from space. When NASA astronaut Kate Rubins sequenced DNA aboard the International Space Station in 2016, it was a game changer. That first-ever sequencing of DNA in space was part of the Biomolecule Sequencer investigation.
Although it’s not as exciting as a science fiction movie may depict, the walls and surfaces of the space station do experience microbial growth from time to time. Currently, the only way to identify contaminants is to take a sample and send it back to Earth.
“We have had contamination in parts of the station where fungi was seen growing or biomaterial has been pulled out of a clogged waterline, but we have no idea what it is until the sample gets back down to the lab,” said Sarah Wallace, NASA microbiologist and the project’s principal investigator at the agency’s Johnson Space Center in Houston.
“On the ISS, we can regularly resupply disinfectants, but as we move beyond low-Earth orbit where the ability for resupply is less frequent, knowing what to disinfect or not becomes very important,” said Wallace.
Developed in partnership by NASA’s Johnson Space Center and Boeing, this ISS National Lab sponsored investigation will marry two pieces of existing spaceflight technology, miniPCR and theMinION, to change that process, allowing for the first unknown biological samples to be prepared, sequenced and then identified in space.
The miniPCR (polymerase chain reaction) device was first used aboard the station during the Genes in Space-1, and, soon to be Genes in Space-2 investigations, student-designed experiments in the Genes in Space program. Genes in Space-1 successfully demonstrated the device could be used in microgravity to amplify DNA, a process used to create thousands of copies of specific sections of DNA. The second investigation arrived at the space station on April 22, and will be tested this summer.
Next came the Biomolecule Sequencer investigation, which successfully tested the MinION’s ability to sequence strands of Earth-prepared DNA in an orbiting laboratory.
“What the coupling of these different devices is doing is allowing us to take the lab to the samples, instead of us having to bring the samples to the lab,” said Aaron Burton, NASA biochemist and Genes in Space-3 co-investigator.
Crew members will collect a sample from within the space station to be cultured aboard the orbiting laboratory. The sample will then be prepared for sequencing, in a process similar to the one used during the Genes in Space-1 investigation, using the miniPCR and finally, sequenced and identified using the MinION device.
“The ISS is very clean,” said Sarah Stahl, microbiologist and project scientist. “We find a lot of human-associated microorganisms - a lot of common bacteria such as Staphylococcus and Bacillus and different types of familiar fungi like Aspergillus and Penicillium.”
In addition to identifying microbes in space, this technology could be used to diagnose crew member wounds or illnesses in real time, help identify DNA-based life on other planets and help with other investigations aboard the station.
“The Genes in Space-3 process will increase the scientific capacity of the ISS by facilitating state-of-the-art molecular biology research for both current and next generation ISS researchers,” said Kristen John, NASA aerospace engineer and Genes in Space-3 project engineer. “The team has put a strong focus on generating a spaceflight-certified catalog of general laboratory items and reagents, and developing common methods and easily customizable reaction conditions for miniPCR and the MinION to enable other ISS researchers to use this technology.”
This process will give scientists on the ground real-time access to the experiments going on in space, allowing for more accuracy and a more efficient use of the time on the space station.
“If you could get a snapshot of the molecular signatures of your research as it was occurring on the ISS, how would you change your experiment?” said Wallace. “Would you change your time points? Provide a different nutrient? Alter growth conditions? You can imagine how, if you had that data, you could adjust your experiment to enhance the insight being gained.”
Closer to home, this process can be used to provide real-time diagnosis of viruses in areas of the world where access to a laboratory may not be possible.

(Highlights: Week of April 17, 2017) - As the International Space Station welcomed two new crew members – NASA astronaut Jack Fischer and Russian cosmonaut Fyodor Yurchikhin -- and a resupply spacecraft, important science investigations continued, including another push to make space travelers more self-sufficient while exploring deep space.
A ground team commanded the Additive Manufacturing Facility (Manufacturing Device) on the space station to print two items over the course of the week. Installed on the station in 2015, the Manufacturing Device is a 3-D printer that uses additive manufacturing to build a part layer by layer using an engineered plastic polymer as raw material.
The Manufacturing Device is another step toward a permanent manufacturing capability on the space station. It will enable the production of components and tools on demand in orbit, which will allow further research into manufacturing for long-term missions. The station crew can use it to print a variety of items to perform maintenance, build tools and repair sections in case of an emergency, leading to a reduction in cost, mass, labor and production time. Further research will also help develop this advanced technology for use on Earth.
NASA astronaut Peggy Whitson performed maintenance on the Microgravity Experiment Research Locker Incubator (MERLIN), replacing some of the desiccant inside to keep the experiments contained inside dry. MERLIN is a locker that can provide a thermally controlled environment for investigations in orbit to both extremes – both as an incubator and as a freezer. It is designed to operate with minimal crew interaction by most of the controls being commanded from the ground.
Among the other human research investigations, Whitson completed another session with the Spaceflight Effects on Neurocognitive Performance: Extent, Longevity, and Neural Bases (NeuroMapping) investigation. This study looks at whether long-duration spaceflight causes any changes to the brain, including brain structure and function, motor control, and multi-tasking, as well as measuring how long it takes for the brain and body to recover from those possible changes. Previous research and anecdotal evidence from crewmembers returning from a long-duration mission have shown that movement control and cognition are affected in microgravity. The NeuroMapping investigation uses structural and functional magnetic resonance brain imaging to assess any changes to crewmembers after long-duration missions. This may also provide additional insight into research on the neural mechanisms associated with behavioral and physiological changes, as well as brain rehabilitation after injury.
Other human research investigations conducted this week include Actiwatch Spectrum, Fluid ShiftsHabitability, and Dose Tracker.
Progress was made on other investigations, outreach activities, and facilities this week, including Device for the study of Critical Liquids and Crystallization (DECLIC HTI-R), METEORCyclopsMCDA Cool Flames Investigation, and Fast Neutron Spectrometer.

el dispensador dice: a veces la duda conduce a una salida inadecuada... a veces el miedo induce a una puerta errada... a veces el instinto lleva el espíritu al lugar elegido... a veces la razón quiebra y destruye los sentidos... a veces la curiosidad abre la entrada al laberinto... a veces la urgencia destroza el pensamiento en equilibrio... a veces la decisión esmerila los caminos... a veces la confusión lleva hacia el desatino... el oficial era un joven sencillo... no se creía lo de los rangos y apenas si sentía jefe de sí mismo... sabía que todos los iguales no pueden ser distintos... sabía que lo diverso enseña el valor de ser igual mientras se es bien distinto... el experimento que los había capturado le estaba indicando que la realidad puede darse vuelta en un santiamén y que las visiones del barco no eran las mismas que había desde la isla... todo parecía indicar que dicha isla existía, pero no en el plano de lo humano... sus mentores habían insertado una realidad dentro de otra... o bien habían abstraído un contexto para utilizarlo como base operaciones de algo distinto... mientras las dudas le daban vueltas en su atribulada cabeza... logró llegar a la biblioteca con la esperanza de hallar algún indicio que le despertase las respuestas sobre qué les estaba pasando a ellos y qué era lo que allí sucedía... apenas ingresó al recinto de la biblioteca observó un libro sobre la mesa... dudó... lo tomó... quiso abrirlo por su tapa pero el libro se puso como piedra... recordó cómo funcionaban las cosas allí y alcanzando la contratapa logró abrirlo... el último párrafo decía: "y estos conocimientos no deben ser dejados en manos de los humanos, por motivo alguno... quien haya leído estas páginas será responsable por las consecuencias de dar a conocer estos contenidos a los humanos"... ¿por qué un libro terminaría así?... buscó el autor de dicho trabajo, pero no lo halló... movió el libro en distintos sentidos y como tantas otras veces, según su ubicación cambiaba el idioma... cuando intentó leer la página previa anterior, la misma casi no se movió, y apenas si pudo leer la palabra sótano... ¿decía sótano o decía sótanos?... intentó leer la hoja pero no hubo caso... algo lo impedía... no lo pensó y descendiendo por las escaleras internas se dirigió a los sótanos... sabiendo que había tantos sótanos como pisos sobre nivel... mientras bajaba iba tocando las paredes para asegurarse que las mismas no tenían puertas ocultas...

cuando alcanzó el primer sótano, que ya había visitado en otras oportunidades, empezó a descubrir que había una conexión a algo semejante a un laberinto... nunca antes lo había notado... ni siquiera recordaba hacerlo visto... y temiendo porque se tratase de una trampa... decidió dejar ese primer nivel de sótanos y bajar al siguiente... allí pudo escuchar con nitidez el ruido descrito por el marinero... había un sonido acompasado semejante a un motor de barco... se lo podía oír pero no había forma de ubicar el sentido de los sonidos... cuando creía acercarse, el compás se alejaba y se diluía... recorrió todos los recovecos posibles que estaban a su vista, pero todo estaba vacío... este nivel tenía muchas habitaciones que parecían haber tenido algún destino de taller, pero no había pañol de herramientas ni nada que indicase suciedad en los suelos o en las paredes... decidió entonces descender otro nivel... muchísimo más amplio que el anterior... tal vez el doble de espacios... le llamó la atención un extraño olor para nada desagradable que salía de alguna parte... miró hacia los techos y nada... comenzó a tocar cada milímetro de pared... su palma de la mano derecha recibía una sensación a seda... pero si tocaba la pared con la mano izquierda esta parecía ser papel de lija... paso a paso fue tocando la pared en las alturas que le daban sus brazos... y cuando ya se había cansado de tanto dar vueltas en espacios vacíos... en el fondo de una de las habitaciones, al tocar la pared, ésta se deformó como si fuese agua... asustado pegó un salto hacia atrás, pero la pared quedó vibrando sin que ninguna otra se moviera... luego de un rato, se acercó con precaución y volvió a tocarla, repitiéndose el fenómeno... se acercó más aún y cuando apoyó la mano, esta desapareció delante de sus ojos quedando inmersa la pared que estaba oscilando... la quitó... dudó... allí había una señal que podía aclarar las cosas... avanzó y al apoyarse con todo el peso de su cuerpo se dio cuenta que podía atravesarla... tuvo miedo de no poder regresar... retrocedió e intentó recordar la disposición de las habitaciones para saber cómo volver allí... su cabeza era un torbellino... descendió dos niveles más repitiendo el trabajo de tocar pared tras pared, sin demasiada precisión... finalmente alcanzó el nivel del mar donde estaba el embarcadero oculto que parecía haber sido diseñado para recibir a por lo menos dos submarinos de gran porte... había un túnel de casi cien metros o poco más de orilla a orilla... y desde al agua hasta el techo había una altura de no menos de cuarenta metros... se sentía impresionante... hasta el fondo de los túneles había como tres cuadras o más... y el fondo parecía ser la roca de la montaña donde todo estaba enclavado... se detuvo a mirar los pisos y las paredes y parecían cortados a espejo... pulidos donde todo se reflejaba... aún cuando no había sombras... raro, pero había que aceptarlo...
