The Future Laboratory (not to be mistaken with the Near Future Laboratory) imagined for Nikon the future of imaging: Context-cameras that can read a photographer’s emotions, devices that enable continuous, spontaneous hands-free image capture and visuals that deliver a full multi-sensory experience (interesting for VR health applications) are the main emerging trends according to the trend forecasters and experts from different fields.
The report is way better than the images above. Be sure to take a look.
We seldom consider the force with which our hearts beat through every moment of our lives. Most of us will only ever feel the dampened strength of these muscles at the arteries of the wrist or neck, perhaps through a stethoscope or in moments of excitement, exertion and fear. Take a moment to consider it now, if you will.
New Technique Lets Scientists See Through Whole Organisms
by Michael Keller
Seeing is believing when it comes to understanding how organisms work. For biologists trying to learn about what’s going on inside a body, one of the biggest obstacles is not being able to put their eyeballs on a part or system without other objects getting in the way. The answer is usually going in with one invasive tool or another, which ends up damaging or destroying the thing they’re trying to investigate.
Now California Institute of Technology scientists say they have improved upon a solution to clearing up the picture. The technique builds on work that garnered widespread attention last year. In that effort, assistant professor of biology Viviana Gradinaru and her team used detergent and a polymer to make a rodent brain transparent for study in unprecedented detail.
This is where the oxygen-exchange with the surrounding tissue happens: In capillaries. Red blood cells give away their oxygen-loaded hemoglobin, receive the produced CO2 and are transported back to the lungs in order to get packed with new oxygen for the hungry tissue. From big arteries, the vessels turn into small arterioles and then capillaries, where the blood oxygen/CO2 gets exchanged. The capillaries lead into venules (little veins) and then back to big veins leading back to the lungs.
Demonstration of LIDAR laser imaging tech developed by Heikki Hyyti features two rotating sensors working simultaneously. The video embedded below shows a data capture using the device whilst moving:
Sensor fusion with inertial and LIDAR data to estimate the position and velocities in real time. The current 3D point cloud is compared to the previous one to reduce errors caused by the integration of noisy and uncertain inertial measurements. The visualization shows two adjacent 3D point clouds on top of each other as the device, attached to an all-terrain vehicle, is driven around a parking lot and a young forest. The color of point cloud is determined by its height. Higher points are colored more lighter and greener as lower points are brownish. The visualization uses open source Point Cloud Library (http://pointclouds.org/) to present 3D data.
Real time LIDAR tech is already used in various ways (one example is in Austrailia, robotic “shepherds” are being trialed to remotely check on cattle), but this is the first example I have seen online using this method.

Galileo and Brahe and Newton, oh my! Some of our favorite manuscript treasures stopped by our Digital Imaging Center last week. Some of them may be making their way to the Smithsonian transcription center soon…
Neuron cell body (purple) with numerous synapses (blue) magnified 80,000x under a scanning electron microscope.
Everone talks about synapses even though some seem to use it to sound cool without actually knowing what it is. So for those persons (and everyone willing to become a bit more educated), here’s a simple explanation.
Information from one neuron flows to another neuron across a synapse. The synapse contains a small gap separating neurons.
The synapse consists of:
a presynaptic ending that contains neurotransmitters, mitochondria and other cell organelles,
a postsynaptic ending that contains receptor sites for neurotransmitters,
a synaptic cleft or space between the presynaptic and postsynaptic endings.
At the synaptic terminal (the presynaptic ending), an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane. The vesicle membrane will fuse with the presynaptic membrane releasing the neurotransmitters into the synaptic cleft.
Occult Chemistry: Atomic Imaging Through the Third Eye
At the turn of the 19th century before the advent of atomic microscopy, a group of theosophists collectively known as “occult chemists” purported to divine the structure of chemical elements through clairvoyant observation. Assisted by the “microscopic vision of the third eye,” the practicioners, led by Annie Besant, C.W. Leadbeater and Curuppumullage Jinarajadasa, carried out a series of observations between 1895 and 1933. The results were published in the lengthily-titled book Occult Chemistry: Investigations by Clairvoyant Magnification into the Structure of the Atoms of the Periodic Table and Some Compounds. Among other “discoveries” was the fundamental particle of the universe, dubbed the Anu after the Sanskrit word for “atoms.” Bearing a notable resemblance to the human heart, the Anu appeared to be composed of vibrating coils swirling in a vortex of energy.
Recently, a fourth-year student at the Museum’s Richard Gilder Graduate School, Phillip Barden, and Curator and Professor David Grimaldi, his graduate advisor, discerned nine “new” species of extinct ants preserved in Burmese amber (which, by the way, is fossilized tree resin).
Two of these species exhibit tusk-like mandibles, and appear to have been quite ferocious, possibly impaling prey with their uniquely expanded mouthparts.
