Massachusetts Institute of Technology can photograph a trillion frames
per second. Compare that with a conventional film camera which takes a
mere 24. This new development in photographic technology has given
scientists the power to photograph the motion of the fastest thing in
the Universe, light. In the video below, you’ll see experimental
footage of light photons traveling at approximately 965
million-kilometers-per-hour (that’s roughly 600 million mph) through
water. The actual event occurred in a mere nano second, but the camera
has the ability to slow it all the way down to twenty seconds. For some
perspective, according to New York Times author, John Markoff,
“If a bullet had been tracked in the identical fashion moving through
the same fluid, the ensuing film would last 3 years.”

A brand new camera developed at Massachusetts Institute of Technology can photograph a trillion frames per second. Compare that with a conventional film camera which takes a mere 24. This new development in photographic technology has given scientists the power to photograph the motion of the fastest thing in the Universe, light.

For some perspective, according to New York Times author, John Markoff, “If a bullet had been tracked in the identical fashion moving through the same fluid, the ensuing film would last 3 years.”
It’s not possible to directly record light so the camera takes millions of scans to recreate each picture. The method has been called femto-photography and according to Andrea Velten, a researcher involved with the project at MIT, “There’s nothing within the universe that looks fast to this camera.”

Virtual reality has been a very long time coming, however probably the most notable strides have come in the past few years. Oculus has led a revitalization in Virtual Reality tech, the development of which had slowed considerably over the previous decade. Now, a resurgence in consumer VR products has resulted in great strides, and inexpensive virtual reality kits like the Samsung Gear VR make virtual reality accessible to almost anybody.
However there is still one key piece missing from the virtual reality puzzle that prevents the consumer from being really immersed in a VR experience. That will soon change, however, because of work being carried out by some researchers in Germany.
A group of researchers from the Human-Computer Interaction (HCI) lab at Germany’s Hasso Plattner Institute have created working prototypes of a device they call Impacto. The gadget is integrated into a band that may be worn on the arm, leg or foot of a virtual reality person. When mixed with a VR experience that incorporates the HCI researchers’ special software, Impacto simulates contact on the wearer so that she or he can really feel objects virtual reality. At least, to an extent.
Examples demonstrated by the group include a boxing sport where the consumer can actually feel the impact from blocked punches on his or her arm, and a game where the participant bounces a soccer ball on his or her foot and can really feel every strike.
Of note, Impacto isn’t a simple vibrate motor shoved into a plastic box. The machine combines a haptic vibration engine with electrical muscle stimulation to actually create a sensation of pushing or pulling, therefore more closely mimicking the sensation of contact from actual physical objects.
“The key concept that allows the small and lightweight impacto device to simulate a powerful hit is that it decomposes the stimulus: it renders the tactile aspect of being hit by tapping the skin utilizing a solenoid; it adds impact to the hit by thrusting the person’s arm backwards utilizing electrical muscle stimulation,” the team, led by Pedro Lopes, stated in an summary covering its research paper on Impacto. “The device is self-contained, wireless, and sufficiently small for wearable use, thus leaves the person unencumbered and able to walk around freely in a virtual environment. The gadget is of generic form, permitting it to even be worn on legs, in order to enhance the experience of kicking, or merged into props, such as a baseball bat.”
Here’s a video of the HCI team’s Impacto prototype in action:
Use cases for Impacto are limited in the meanwhile because of the device’s shape and size, however it’s totally possible to use the same technology in both smaller and bigger units. As a result, different Impacto modules could possibly be combined to form a suit of sorts that may give the wearer multiple contact points. So, rather than only being able to feel a jab to the arm or a soccer ball bouncing off of a foot, virtual reality users may feel contact from VR objects throughout their bodies. The researchers mentioned that they already have plans to create new Impacto modules for the stomach area and shoulders.

Cuba achieved food security with out destroying its environment, and the remainder of the world has finally noticed.
Cuba is presenting a number of of its unique bio-technologies at a global business fair this week, drawing further attention to a sector of the Cuban economy that’s been producing substantial interest overseas.
The Cuban Center for Genetic Engineering and Biotechnology presented numerous biotechnological improvements at the fair: all eco-friendly and biodegrable alternatives to traditional technologies, which may assist the transition towards a more sustainable model of agriculture.
Amongst them was an immunogen called “Gavac,” that provides for better control over ticks and tick-related infections in cattle, according to Dr. Hector Machado of Cuba’s Heber Biotec firm.
Gavac’s formulation reduces the usage of chemical pesticides, stated Machado, while diminishing the danger of diseases being transmitted by ticks, enhancing an animal’s natural capacity to respond to an infection with out increasing their resistance to treatment.
Gavac has already been commercialized in Venezuela, Mexico, Colombia and Brazil. Its awaiting approval to be used in Nicaragua, Panama and Costa Rica.
Other biotechnological merchandise included Acuabio’s range of nutritional complements used in aquaculture in order to boost the growth of larva and enhance their immune systems till they develop into adults, providing them better defences against infections.
The HeberNem eco-friendly pesticide against roundworms, or nematodes, is also increasingly well-liked inside Cuba, and shall be introduced in the fair this year.
The fair – one of the largest business events within the Caribbean – aims to draw investment in Cuba. This year, a number of U.S. corporations are attending the fair, the first time U.S. firms will be attending since the fair was launched 33 years ago.
Cuba has been attracting attention in recent years for its model of agriculture, because it has been able to develop low cost and eco-friendly technologies which have helped the nation to achieve a certain degree of food security with out damaging the environment. With the environmental and financial challenges the world is now facing, the Cuban model – built in a time of crisis, after the United States sanctions – is seen as offering potential solutions to many countries in the world.
