These Robots Can Build Ikea Furniture

2018-04-22    0 views
Ikea furniture-building robots are here.

These researchers from Nanyang Technological University designed a pair of robotic arms that can assemble an IKEA chair in 20 minutes. The researchers reported their findings in the Journal of Science Robotics.

The robotic arms are equipped with 3D cameras, force sensors, are grippers. Researchers first programmed a manual into the robot — it then took 11 minutes to identify and match materials to the manuals and to come up with an action plan. From there it took 9 minutes to build the chair.

“If you think about it, it requires perception, it requires you to plan a motion, it requires control between the robot and the environment, it requires transporting an object with two arms simultaneously,” explained Dr. Quang-Cuong Pham, an assistant professor of engineering at the university and one of the paper’s authors to the New York Times. “Because this task requires so many interesting skills for robots, we felt that it could be a good project to push our capabilities to the limit.”'

Robots have built IKEA furniture, but nothing as complex as a chair. The researchers hope to design a robot that can build furniture by mimicking a human or with spoken instructions. Who knows, hopefully with creations like this robot, going through the annoyance and time of assembling will be a thing of the past.

Scientists in Italy are studying what effect
human emotions have on plants.

Stefano Mancuso, professor of Plant Physiology
at the University of Florence, is leading the study.

He’s joined with German artist Carsten Höller.

Höller said that it’s the first experiment of its kind.

The Florence Experiment will have people wear a belt with a bean plant in it.

they’ll go down a slide with the belt on.

When they reach the bottom, they’ll hand the plant to a researcher, who analyzes it.

The sliders will fill out a questionnaire, explaining how they felt during the way down.

Researchers will compare the emotions to the plant, using the Licor 6800 instrument.

It analyzes different photosynthetic parameters of the plant’s leaves and gas exchanges.

“Researchers analyze the photosynthesis—which is the engine, the heartbeat of plants,” said Mancuso.

“And then they analyze the Volatile organic compounds, that are messages sent by the plants."

Doctors from Audeara have designed headphones that reduce hearing loss by tailoring its sound to the user’s ability to hear.

Doctors Chris Jeffrey and James Fielding invented the device after getting fed up with their patients waiting for hearing tests.

The headphones enable users to monitor their hearing loss over time and upload their hearing profile onto devices via Bluetooth.

It also protects a user's hearing by reducing noise distortion and the need for them to turn the volume up.

Dr Fielding said, “the response from people who use the headphones for the first time is amazing. They’re usually overwhelmed at the difference in what they hear – and they wonder why they’ve been using off-the-shelf headphones for so long.”

The earphones were launched this month after a successful crowdfunding campaign that brought in a staggering £320,000 ($450,000 USD approx) in just 15 hours on Kickstarter.com.

A spokesman from Audeara said, “The headphones are designed by doctors and engineers to deliver perfect sound, always."

According to a report by Gizmodo, researchers from the University of Portsmouth and the US Department of Energy’s National Renewable Energy Laboratory were conducting an experiment on a naturally occurring plastic-munching enzyme when they discovered they discovered a synthetic version that is 20 percent more efficient. John McGeehan, lead author of the new study, in a statement, “Serendipity often plays a significant role in fundamental scientific research and our discovery here is no exception. Although the improvement is modest, this unanticipated discovery suggests that there is room to further improve these enzymes, moving us closer to a recycling solution for the ever-growing mountain of discarded plastics.”

Ancient Babylonian tablet - world's first trig table

2018-04-17    0 views
A 3,700-year-old Babylonian tablet was recently translated and might rewrite the history of math, suggesting that trigonometry may have been developed before the ancient Greeks.

The researchers said the tablet proves that the Babylonians developed trigonometry some 1,500 years prior to the Greeks.

“Our research reveals that Plimpton 322 describes the shapes of right-angle triangles using a novel kind of trigonometry based on ratios, not angles and circles,” Dr. Daniel Mansfield of the School of Mathematics and Statistics at the University of New South Wales Faculty of Science, said in a university news release. “It is a fascinating mathematical work that demonstrates undoubted genius. The tablet not only contains the world’s oldest trigonometric table; it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry.”

Los cráneos de tiahuanacotas tienen rostro 3.000 años después

2018-04-15    0 views
(EFE) Los antiguos pobladores de Tiahuanaco, capital de un imperio prehispánico en Bolivia, han recobrado su rostro 3.000 años después, gracias a la reconstrucción en tres dimensiones de sus cráneos deformados, en un proyecto similar a la reconstrucción facial del libertador Simón Bolívar.
Tres milenios después aún se desconoce por qué deformaban sus cráneos de forma intencionada "a partir de los seis meses de edad, cuando según algunas teorías, ponían algunas tablas o telas apretando en la cabeza", comenta a Efe el antropólogo forense Luis Castedo.
Se queja del frío, ya que el laboratorio debe mantener en todo momento una temperatura baja y una ventilación adecuada para preservar los huesos de hace más de 3.000 años, pero eso no le impide trabajar con eficacia.
El trabajo de Castedo es minucioso y preciso, rodeado en todo momento de cráneos y herramientas para sacar los moldes exactos que logren entender esas cabezas alargadas de la cultura prehispánica.
"El proceso que se está siguiendo es el análisis del cráneo, donde se hace el estudio craneométrico, se toman las medidas, se van determinando los puntos faciales para luego tener todos los marcadores para poder poner el tejido blando del rostro", relata.
La reconstrucción, mantiene, "asegura un 96 por ciento de similitud", porque no se puede conocer "el color de ojos, el pabellón auditivo y el color de piel a partir del cráneo".
El objetivo es conocer cómo eran los rostros de estos habitantes de la zona andina a través de una tecnología que ya se ha utilizado en Perú, Venezuela o Brasil.
Las técnicas de reconstrucción, pioneras en Bolivia, "ya se habían realizado en el Perú por ejemplo, con la reconstrucción de San Martín de Porres -considerado el primer santo mulato en América- y en Venezuela con la reconstrucción facial del libertador Simón Bolívar".
Los venezolanos pudieron ver el rostro de Simón Bolívar (1873-1830), llamado El Libertador por haber liberado a Bolivia, Colombia, Ecuador, Panamá, Perú y Venezuela del imperio español, gracias al trabajo de la antropóloga Lourdes Pérez en 2012.
El forense necesitó seis meses para reconstruir los tres primeros cráneos y recibió la ayuda de una artista plástica, "que ayudó con la fisonomía", y dos antropólogos, "con el modelado".
El Museo Nacional de Arqueología de Bolivia, donde trabaja Salcedo, cuenta con 150 cráneos tiahuanacotas con deformación y la idea es reconstruir físicamente hasta unos 30 o 40 y el resto realizarlo de forma digital.
Luis Castedo, único antropólogo forense en Bolivia, ha sido el encargado de reconstruir los tres primeros cráneos, dos de adulto y uno de un infante de 2 años, para entender mejor el pasado boliviano.
"El objetivo de esta reconstrucción es conocer la fisonomía de los antiguos pobladores tiahuanacotas. A partir de esta gestión el impulso de la ministra -de Culturas, Wilma Alacona- es el interés de preservar el patrimonio cultural", comentó a EFE.
Este proyecto piloto surgió en 2015 gracias a la gestión del centro de investigaciones arqueológicas y antropológicas de Tihuanaco, con la elaboración y reconstrucción de moldes plásticos de cráneos con deformación intencionada.
El Ministerio de Culturas de Bolivia decidió entonces apostar por el programa para "preservar el patrimonio cultural", en palabras de la ministra.
Este proyecto piloto también servirá para conocer el coste total de reconstruir cada cráneo, por lo que el programa continuará en función de la cuantía, que todavía se desconoce, según el ministerio.
El trabajo de Castedo se mostrará en una exposición temporal, con fecha aún por determinar, y contará con un espacio para que los niños puedan conocer mejor a sus antepasados a través de figuras que podrán modelar.

3D-printed house unveiled

This is the first house ever built by 3-D printers
on-site for human habitation.

French engineers unveiled green social housing.

Two outside layers of a special polymer
called polyurethane, and a concrete inner layer
make for extremely effective insulation.
Once you've printed the material you've used very little material,
and produced zero waste. The other reason why
we can say the material is good, is that this material
once it's laid down allows us to achieve efficiency in the house
which means that the wall is so insulating,
you'll use very little energy to heat this house for 100 years."
Professor Benoit Furet, University of Nantes

Backers say it’s progress in green construction.

The first tenants are expected to move into this
five-room house in June 2018.

2018-04-13    0 views
The Metropolitan Transport Agency (MTA)
will launch the mobile application "MYmta."

The app will allow commuters to see in real time
the status of trains and elevator outages.

as well as locate nearest stations and bus stops.

The MTA asked two of its current employees to
test out the app ahead of its launch.

MTA spokesman Jon Weinstein says the app
will be available to commuters within weeks.


[[Michelle, New York Commuter]]
All I know is about the bus right now. So I don’t know about
any train apps yet. So yeah, that’d be good. Yeah, I think that’d be
helpful

Some commuters think the MTA should focus
on improving current services before offering
new ones.

[[Gervine Terry, New York Commuter]]
I have been stuck in Manhattan on the F for more than 45 minutes.
The 7 is a problem most of the time in the morning. They have
a lot of signal problems. We need a lot of repair. But they’re
constantly working on it. But I can't see the results.

In the wake of the Cambridge Analytica scandal, the hashtag "#DeleteFacebook" has trended, and you might even know people who cut ties with their Facebook account. According to a new study conducted by Techpinions, 9% of Americans say they have deleted their Facebook account altogether over privacy concerns. 35% say they're using Facebook less than they used to. Techpinions thinks that lower engagement is actually the real risk for Facebook, not necessarily people deleting their accounts.
