    Listening to music extends exercise duration
    Listen to music during exercise - it improves your performance

    Researcher Waseem Shami, MD at the Texas Tech University Health Sciences has found that listening to music during a cardiac stress test might help extend the duration of exercise. This test is widely used to determine the effects of exercise on heart and the present study is the first of its kind to show that music helps motivate people to exercise longer which is extremely critical for overall heart health. Although the present study was conducted only on individuals undergoing stress testing, Dr Shami believes that these finding could be applied to the general population to help them motivate to exercise regularly.

    Search engines aren't as neutral as they claim to be

    Safiya Umoja Noble in her latest book, Algorithms of Oppression, recounts a horrifying experience in which her search of 'black girls' resulted in porn pages. Noble who is a USC communications professor has long argued that search engines aren't as neutral as they claim which might lead to biases against certain ethnic groups and genders. Since the public relies on search engines for the truth or credible news, throwing biased news towards them shapes thought and discussions towards unwanted directions. She argues that since machine learning algorithms already use biased data, the results as ought to be biased. The question now is: Is it too late to change all this?

    Most of the energy in buildings is lost through windows
    Clever coating for smart windows

    Researchers have developed a very thin self-regulating film made of vanadiumoxide that can be coated on windows to regulate indoors temperature. By passively changing the conductive properties of vanadiumoxide under influence of ambient temperature, the coating lets more heat in when it is cold, and blocks sunlight when it is cold. Coating of windows with this film is expected to spare significant amounts of energy for heating and cooling of buildings, resulting in major financial and environmental benefits.

    Giant atom containing other atoms created as a new form of matter - short science news

    In a standard atom there is a certain space between the nucleus and the surrounding electrons. A team of physicist decided it would be a good idea to fill this space with… well, other atoms! They used strontium ions which, using a laser, were converted into a Rydberg atom, an atom with a huge distance between the nucleus and the orbiting electron. Thus, the electron will orbit not only around its own nucleus, but also around many other normal strontium atoms that easily fit in this space. This new exotic state of matter, called Rydberg polarons, can only be detected at very low temperatures.

    Artificial eye with a metalens and an artificial muscle

    Researchers have advanced to a new generation of artificial eyes by combining a metalens with an artificial muscle. This new electronically controlled eye is thin and flat, and can focus in real time, just like the human eye. On top of this, the new metalens corrects for aberrations such as image shift and astigmatism to avoid image blurring. The new metalens may be used for zooming and autofocus in future cameras in e.g. cell phones or microscopes.

    A new device allows for collection of blood without using needles - science news

    A device that allows collecting of blood without the use of needles is being developed by a startup from EPFL, Switzerland. The device will allow people to collect blood samples at home, without pain. The company did not reveal information about how the device works, but it is known it allows drawing enough blood for most tests in a similar amount of time as conventional methods. The blood samples still need to be sent to a specialized laboratory for testing. Interestingly, the system is connected to the internet to ensure that each blood sample is traceable from the moment of the sample collection until the results are released.

    Photons interact to form new photonic matter. Physics short science news

    When two beams of light intersect, the photons from the two sources ignore each other and pass by without any interaction occurring. However, under special conditions the photons could be forced to interact. This is exactly what a new study reports: photons from two light sources were made to interact and this event resulted in the formation of a new kind of photonic matter. The physicists observed groups of three photons interacting when a weak laser was shone through a dense concentration of ultracold rubidium atoms. Besides the fundamental scientific importance of the discovery, there are also practical applications such as the field of quantum computers.

    Combining blockchain with genetic data. Image from pixabay.com
    Lets put your genetic code on the blockchain and share it

    Traditionally, when you do a DNA test, the company which does it owns the genetic data. However, Nebula Genomics has proposed to sequence the genome for $1000, give insights on it and then secure it on the blockchain. Pharma companies need large genetic databases to develop new drugs. This sets the way for individuals to sell their genomic data directly to these companies thereby foregoing middlemen. With the plans going underway soon, the implications are limitless.

    Volcanic ash may help reduce energy required to build cities Credit: MIT News
    Volcanic ash reduces the energy required to manufacture concrete

    Scientists have discovered that adding volcanic rock dust to concrete may be an effective additive, leading to a decrease in energy consumption. According to the study, it takes 16 percent less energy to construct 26 concrete buildings made with 50 percent volcanic ash, compared to traditional concrete. This makes possible the construction of sustainable cities with low environmental impact. Currently the manufacturing of traditional Portland cement is responsible for about 5 percent of the world’s carbon dioxide emissions. This raises the possibility that the cities of the future will be made of volcanic ash to reduce the environmental footprint.

    Surgeons see inside the body during surgeries using augmented reality

    A team from Imperial College London at St Mary’s Hospital used for the first time the Microsoft HoloLens augmented reality headsets to perform reconstructive lower limb surgeries. The headset overlays images from CT scans, including the 3D location of blood vessels and bones, onto the patient’s limbs. This allows for better precision during the identification and reconnection of the key blood vessels, ultimately improving the outcome of the surgeries. The surgical teams concluded that the HoloLens was a success and augmented reality technologies could soon be found in hospitals all over the world.

    New technique allows repeated change of color for 3D printed objects

    The present 3-D printing technology does not allow the modification of a printed object once it is finished. Researchers from MIT now present a revolutionary technique that allows repeatedly changing the color of a 3-D printed object, after fabrication. They used a proprietary ink which changes color when exposed to ultraviolet light. This allows the change in color to occur in about 20 minutes. Currently the method is optimized for plastic objects but the team is working on expanding this to other types of materials such as clothing.

    New artificial synapse works faster than synapses in the brain

    Researchers at the National Institute of Standards and Technology (NIST, USA) have developed a superconducting switch that works like a natural synapse in the brain , but a lot faster. It is designed to connect processors (like connecting brain cells) and to store memory (synaptic plasticity) in future computers that operate like the human brain. Like a synapse, the switch integrates multiple bits of information in stead of only 1 or 0 bits, processes this, and fires a burst of electricity depending on the outcome of information processing. Technical hurdles need to be taken, however, before the switch can be used for real computing.
