دراسة: طلاء أسطح المباني بالأبيض يخفف أثر ارتفاع حرارة الأرض

أشارت نتائج دراسة عن المناخ إلى أن طلاء أسطح المباني في مدن العالم باللون الأبيض قد يخفض درجات الحرارة في مناطق الحضر بشكل كبير وربما يؤدي إلى تخفيف اثر ارتفاع حرارة الأرض.

وقال كيث اوليسون المشرف على الدراسة إن البحث الجديد يظهر أن الأسطح البيضاء من الناحية النظرية على الأقل قد تكون طريقة فعالة في الحد من درجات الحرارة بمناطق الحضر مضيفا أن هذه الفكرة تتطلب المزيد من البحث ورؤية ما إذا كان ممكنا بالفعل طلاء أسطح مباني المدن باللون الأبيض.
واستخدم الباحثون نماذج الكمبيوتر لإجراء محاكاة لحجم الأشعة الشمسية التي ستمتصها الأسطح في المناطق الحضرية وقدروا أنه في حال طليت أسطح المدن في كل أنحاء العالم بالكامل باللون الأبيض فإن ذلك يؤدي إلى خفض اثر جزر الحرارة بواقع 33 في المئة وبالتالي انخفاض حرارة المدن بنحو أربع درجات مئوية وسطيا.
كما تعمل الأسطح البيضاء على إبقاء حرارة المباني من الداخل أكثر لطفا.
وكشفت تجربة المحاكاة أنه في منطقة نيويورك ستعمل الأسطح البيضاء على تلطيف درجات حرارة المدينة الأمريكية بعد الظهر في الصيف بواقع درجة مئوية.
وفي عالم الواقع يصعب طلاء أي سطح باللون الأبيض بالكامل بسبب منافذ التسخين والتبريد والفتحات الأخرى.
بدوره أيد ستيفن شو وزير الطاقة الأمريكي الحائز على جائزة نوبل في الفيزياء فكرة الأسطح البيضاء التي اعتبرها بعض المنتقدين خيالية العام الماضي كما أشار بحث لعلماء بالمركز الوطني الأمريكي لبحوث المناخ إلى أن الفكرة محتملة.

ويؤثر تغير المناخ على المدن بشكل أكبر من القرى لأن الكثير من المسطحات فيها ومنها الطرق الممهدة بالإسفلت ذي اللون الداكن والأسطح المغطاة بالقار تمتص حرارة الشمس أكثر وهذا يخلق ما يسمى ب جزر الحرارة حيث تكون درجات الحرارة أعلى بما يتراوح بين درجة وثلاث درجات مئوية من الريف.

ومن شأن الأسطح البيضاء والطرق الأفتح لونا أن تعكس هذه الحرارة بدلا من امتصاصها.

Plustek helps you create audio books.


"Do scanners merely turn printed text into digital format? Apparently the answer is no, as the ‘BookReader’ launched by Cerritos, CA-based manufacturer Plustek Technology Inc also reads the book for you. Mainly aiming at visually impaired users who still want to read books, the device not only uses the optical character recognition software to convert printed books or documents into digital formats, but adopts the text-to-speech recognition software to translate them into audio files. So simply put a book page on the scanner, press the button and then you can listen to the page. That’s cool!
The device could scan in three different modes: plain text, a grayscale PDF scan and a color scan." inewidea.com

“Blue Collar” Lamp


Though we’re now in a modern era, unexpectedly we’ve kept looking back to find something traditional and to rebuild them with a new look. And this so-called“Blue Collar” lamp is rightly a perfect example. It looks like a hurricane lamp, but the lampshade is comparatively more gorgeous, either gold-plated or chrome-plated. Very nice.

Smart clothes could take photos

Clothes could one day take snaps of everything happening around whoever is wearing them.
US researchers have made smart fabric that can detect the wavelength and direction of light falling on it.
The research team has found a way to accurately place sensors in each fibre and co-ordinate the electrical signals they send when light falls on them.
The results were a step towards "ambient light imaging fabrics" said the researchers.
Led by Dr Yoel Fink from the Massachusetts Institute of Technology, the researchers have extended earlier work that placed sensors in relatively large polymer fibres.
Dr Fink and colleagues found a way to stretch the 25mm strands of polymer into much thinner fibres while maintaining the relative positions of the sensors.
This earlier work has led to the creation of very long and flexible light and temperature sensors that may find a role in smart fabrics for soldiers or those working in hostile environments.
In their latest work, described in a paper in Nano Letters, these thinner strands were woven into a 0.1m square section of fabric. The careful creation of the fibres and positioning of the light-sensitive elements meant that the team knew which signals were being sent by which sensors.
This enabled the team to reconstruct, albeit crudely, an image projected onto the small square of fabric. The researchers said their work was an "important step" towards finding ways to get many nanoscale devices working together.

Non-invasive brain surgery proves successful

Not many patients can imagine having a glass of champagne with their surgeons straight after brain surgery but that is exactly what is happening at a Zurich hospital.
Swiss doctors have successfully carried out the world's first non-invasive brain surgery with use of high-intensity focused ultrasound (HIFU). Ten adult patients, who were awake during the revolutionary painless procedure, have been treated at University Children's Hospital Zurich since September 2008 as part of a clinical study. The results were published this week.
All interventions were completed successfully and without complications under the direction of professors Daniel Jeanmonod and Ernst Martin.
"This fully non-invasive procedure opens new horizons for neurosurgery and the treatment of different neurological brain disorders," Ernst Martin, director of the hospital's Magnetic Resonance Centre told swissinfo.ch. The list of diseases and conditions which could be treated with this safe and effective technique includes Parkinson's, Alzheimer's, epilepsy, brain tumour and stroke.

Martin and Jeanmonod have been working on patients with neuropathic pain due to functional brain disorders. Specifically, they are people who experienced pain in amputated or paralysed parts of the body.
"The origin of the pain does not exist anymore but the brain projects the pain so that is why we operate on the brain," Martin explained. The patients have all remained pain-free since their operations.
HIFU has been used for some years in the treatment of uterine fibroids and tumours of the prostate gland. The ultrasound beams heat up the problem area, creating a lesion and rendering it inactive.
This is the first time that the technique has been applied to the brain through the intact skull for non-invasive neurosurgery.

Charge on single atoms measured


The amount of electric charge on single atoms has been measured by researchers reporting in Science.

While individual atoms' charges have been measured before, the prior method required that the atoms be on the surface of a conducting material.
The new approach used a tiny tuning fork-like device that was deflected minuscule amounts by the attraction or repulsion of the atoms.
The approach will aid in the design of devices such as solar cells.
Gerhard Meyer of IBM's Zurich research laboratory first showed in 2004 that individual atoms' charge could be measured using a device known as a scanning tunnelling microscope (STM).
An STM has a tiny metallic tip - ending in one or a few atoms - which measures physical properties of microscopic-scale samples by passing a small current through them and measuring how this current varies across a sample.
However, an STM requires that the samples be at the surface of a conducting material, so that charges can move around or be lost entirely to this conducting substrate.

The new work hinges on the use of a research tool called an atomic force microscope, or AFM, which as its name implies can measure forces at the atomic level.

Molecular electronics, like this transistor, require atomic precision
An AFM employs a similar tiny tip, ending in just one atom. The tip is suspended from a cantilever - a beam just a few billionths of a metre across that acts like a diving board.
The researchers attach a small voltage to the diving board and set it vibrating near its natural resonant frequency.
When the tip comes close to a charged sample, the vibration's frequency changes slightly as the "opposite charges attract" principle gets to work on the single-atom level, changing the force acting on the tip and the cantilever.
The deviations of the cantilever are less than an atom's diameter, and the team can measure whether a gold or silver atom has a single extra electron or lack of one.

It is an unthinkably precise measure; more than a billion billion electrons pass through a 60W light bulb every second.
Yet the fine details of the movement of individual charges are critically important, both for existing pursuits such as solar cells and for the nascent field of "molecular electronics", in which molecules act as circuit elements.
The charge transfer processes that ultimately determine a solar cell's efficiency will be easier to optimise knowing the exact movements of charge within materials.
"That is what makes this technique so important; it's not only the charge state of an atom but we want to go further and investigate molecules and measure distribution of charges," IBM's Leo Gross told the BBC.
The approach will also allow researchers to see at the most fundamental level how electric charge transfers in catalysts, or how charges get separated in molecular complexes such as some of the machinery of photosynthesis.
"We're not directly aiming at making a photovoltaic cell or a computer in our system," Dr Gross said. "We're trying to understand the basics of the processes in such devices."

Man-made star to unlock cosmic secrets

When the world's most powerful laser facility flicks the switch on its first full-scale experiments later this month, a tiny star will be born on Earth.

The National Ignition Facility (NIF) in California aims to demonstrate the feasibility of nuclear fusion, the reaction at the heart of the Sun and a potentially abundant, clean energy source for the planet. But whilst many eyes at the facility will be locked on the goal of satisfying humanity's energy demands, many scientists hope to answer other fundamental questions for mankind. "In recreating the process of fusion it was always understood that we could pursue three areas of interest and value," explained Dr Erik Storm of the Lawrence Livermore National Laboratory (LLNL), the home of NIF. First and foremost, NIF has been built for national security purposes, to study the conditions that exist in nuclear explosions and the way that nuclear weapons perform.

"That gives you an ability to maintain a credible nuclear deterrent in the absence of underground nuclear testing," said Dr Storm. "Then, we can study the physics of fusion - can you make a fusion power plant here on our planet? And we can do basic physics and planetary science."

Können Gehirnforscher unsere Gedanken lesen?

Eine leistungsstarke Abbildungs-Technologie hat zu einem besseren Verständnis geführt, wie unser Hirn funktioniert. Müssen wir nun besorgt sein, dass unsere Gedanken von Aussen kontrolliert werden?

In Genf diskutierten im Rahmen der Internationalen Woche des Gehirns (Brain Week) Neurowissenschafter über die Erschliessung der Geheimnisse in unseren Köpfen und etwaige daraus erwachsende ethische Probleme. Brain Week hat sich in den letzten 12 Jahren in Europa etabliert. In der europäischen Dana Allianz für das Gehirn (EDAB), welche die Brain Weeks jeweils koordiniert, sind über 170 Gehirnforscher aus 27 Ländern, darunter fünf Nobelpreisträger, organisiert. Der Verein hat sich zum Ziel gesetzt, die Öffentlichkeit über die Gehirnforschung zu informieren. In den vergangenen 15 Jahren hat sich die Neurowissenschaft spektakulär entwickelt. Sie konnte von der deutlich leistungsfähigeren und präziseren Magnet-Resonanz-Tomographie (MRT) profitieren, sagte Patrik Vuilleumier, Direktor des Neurowissenschaftlichen Zentrums der Genfer Universität vor 300 interessierten Zuhörern.

عالمان يصممان رحلة افتراضية داخل الثقوب السوداء

دبي، الإمارات العربية المتحدة (CNN) -- قام العالمان الأمريكيان، آندرو هاميلتون وغافن بوليموس، بتصميم برنامج، قاما من خلاله برحلة افتراضية داخل الثقوب السوداء التي يعج بها الكون، وذلك كما ورد على موقع هاميلتون الإلكتروني.
وفي أبحاثهما حول الرحلة الفضائية الافتراضية، كشف العالمان عن أن الكثير من التصورات التي يحملها الناس وأفلام الخيال العلمي ليست دقيقة على أقل تقدير، بحسب هاميلتون.
فباستخدام برنامج كمبيوتري ومعادلات معقدة، ترتبط بنظرية ألبرت آينشتاين عن النسبية العامة، تمكن العالمان من وضع تصور عما يمكن لإنسان أن يراه داخل ثقب أسود، رغم أنه بحاجة إلى ثلاثة عيون لتحقيق الرؤية الشاملة وليس فقط لعينين اثنتين.
وحول الثقوب السوداء، قال هاملتون: "إن الثقوب السوداء من أبسط الأمور في الكون، لكننا نفكر بها باعتبارها أموراً معقدة لأنها توصف بحسب مفاهيم رياضية معقدة."
وتوضيحا لطبيعة الثقوب السوداء، يوضح هاميلتون أنها "بسيطة غاية البساطة، فهي أبسط من بكثير من الشمس، وأبسط كذلك من النجوم، بل وأبسط حتى من البشر أنفسهم."
وأثبتت الرحلة الافتراضية، أن الذي يدخل في أحد تلك الثقوب، يتعرض لقوة جاذبية كبيرة جداً تشده إلى الأعلى وإلى الأسفل، ومن اليمين إلى اليسار وبالعكس، بحيث أنها قد تغير من طول الشخص وحجمه كي يصبح أطول وتتمدد أطرافه، هذا إن لم يتمزق بالكامل.
وعلى عكس ما يشاع، كما بين هاميلتون، فإن الرؤية في واحدة من الثقوب لا تكون منعدمة بل مشوشة للغاية، بحيث يحتاج المرء إلى ثلاث عيون كي يتمكن من الرؤية بداخلها بوضوح، ويحدد المسافات فيها فعلياً.
وتتركز رؤية الكون من حول الشخص الذي يدخل في ثقب أسود، بشريط حوله نظراً للسرعة الهائلة التي يتداخل فيها عنصرا الزمان والمساحة.
ويشبه هاميلتون الثقب الأسود وكأنه أحد شلالات الماء، التي نراها في الطبيعة، ولكن بدلا من أن يسقط الماء في الشلال فإن الفضاء المحيط به هو الذي يتداعى، ومن هنا تأتي فكرة امتصاص الثقوب السوداء للأشياء من حولها.
يذكر أن الثقوب السوداء عبارة عن أجرام في الكون، تتشكل بعد انهيار النجوم الهائلة الحجم وتصبح الجاذبية قها هائلة، بحيث أنها تمتص كل ما حولها، بما في ذلك الضوء.
ويعتقد البعض أن الثقب الأسود معتم، ربما بسبب الاسم، ولكنه في الواقع ليس كذلك فهذا الاعتقاد عبارة عن خطأ شائع.

Power Your Gadgets with Water

Hook the “Self Generator" up to an available faucet and the water will turn a turbine and generate enough electricity to power an electric toothbrush, a shaver or a hair dryer. That’s the theory, at least. In practice, we doubt that Jin Woo Han’s concept design would do anything more than trickle-charge (sorry) the most undemanding of gadgets and, as you will see below, offer an almost unlimited supply of puns.
The idea is sound, though — the pressure that sprays the water from your taps is harnessed to drive a power outlet, rated at a rather optimistic 220 volts. Any unneeded juice is stored in a battery and the water itself drops from the tap at a reduced speed. There is also an indicator on the side of the generator to tell you just how much energy you have saved.
As a concept, it has potential (sorry again), but we feel impelled (ahem) to point out that electricity and water don’t mix. And that, despite Han’s claims, a “mixer" is not something found beside the faucet.

Ein Algorithmus gegen den Jetlag

Kommt die innere Uhr durcheinander, büsst der Körper meist mit Müdigkeit oder Schlaflosigkeit. Lichttherapien, basierend auf mathematischen Modellen aus der Regelungstechnik, könnten ein solches Ungleichgewicht schneller wieder einpendeln. Bioinformatiker entwickelten dazu die passenden Algorithmen.

Die Ferienzeit steht vor der Tür und so manchen plagt der Bammel vor dem bevorstehenden Flug. Einerseits ist da die Flugangst, andererseits der Jetlag, welcher gerade bei weiten Flugstrecken die ersten Ferientage durch Müdigkeit und Lustlosigkeit verderben kann. Millionen von Flugpassagieren leiden jährlich an einem Jetlag, weil ihr Körper Mühe hat, sich der neuen Zeitzone anzupassen. Für bestimmte Berufsgruppen, wie zum Beispiel Piloten, ist der Jetlag praktisch ein Dauerzustand. Auswirkungen sind Müdigkeit oder Schlaflosigkeit, in schlimmeren Fällen Depressionen und einige Forscher gehen sogar von einem Zusammenhang zwischen Jetlag und erhöhtem Krebsrisiko aus.

Zumba phone - COOL!



This so-called Zumba phone is claimed to be the first fully hands-free mobile phone. It is as small as a credit card and the real phone part is located at the back of the “credit card”. All the functions are controlled by your voice. In addition to this hands-free advantage, it seems that this phone is pretty secure as well. Since all the information is stored on a website called “Zumba Lumba”, even if someone get your phone they will not be able to control .

Bilder, die mit der Kraft der Sonne laufen


Seit knapp zwei Jahren sind Christof Seiler und Reto Schmid mit dem Cinéma Solaire unterwegs. Den Strom für die Filmprojektion liefert die Sonne. Jetzt haben sie den Solarpreis 2008 gewonnen.

Ein Segel mit flexiblen Solarzellen, eine "Lichtspeicherkiste", ein 16mm-Projektor: Das ist das Cinéma Solaire. Erfunden haben das Wanderkino der nachhaltigen Hightech-Sorte Christof Seiler und Reto Schmid. Für die Umsetzung ihrer bestechend einfachen Idee werden die beiden findigen Köpfe am 5. September mit einem der neun Schweizer Solarpreise 2008 ausgezeichnet.

"Am Tag sammeln wir Licht und lassen dies am Abend durch den Projektor frei", beschreibt Christof Seiler die Idee des Cinéma Solaire gegenüber swissinfo.

Keine Schildbürgerei
Die Anspielung auf die Schildbürger ist gewollt. Diese stellten tagsüber Eimer auf, um das Sonnenlicht einzufangen. Damit wollten sie ihr fensterloses prismenförmiges Rathaus beleuchten. Mit ihrem Vorhaben scheiterten die Schildbürger jedoch kläglich.

Anders der 27-jährige Winterthurer Interaktionsleiter Anders Seiler und der 29-jährige Bieler Architekt Reto Schmid: "Seit eineinhalb Jahren funktioniert unser Cinéma Solaire".

Herzstück des solaren Wanderkinos sind das Sonnensegel sowie die Lichtspeicherkiste. Auf dem fünf mal drei Meter grossen Segel sind flexible Solarzellen befestigt.

Monkey's brain controls robot arm

Monkeys have been able to control robotic limbs using only their thoughts, scientists report.
The animals were able to feed themselves using prosthetic arms, which were controlled by brain activity. Small probes, the width of a human hair, were inserted into the monkeys' primary motor cortex - the region of the brain that controls movement. Writing in Nature journal, the authors said their work could eventually help amputees and people who are paralysed.
