This is the most accurate post about anxiety i have ever read. Extremely well explained and articulated. I live this everyday. Have since childhood:

1. They don’t hide their anxiety, they hide their symptoms. To have concealed anxiety isn’t to deny having it – only to do everything in your power to ensure other people don’t see you struggle.

2. They have the most anxiety about having anxiety. Because they are not comfortable letting people see them in the throes of an irrational panic, the most anxiety-inducing idea is… whether or not they’ll have anxiety at any given moment in time.

3. They come across as a paradoxical mix of outgoing but introverted, very social but rarely out. It is not that they are anti-social, just that they can only take being around others incrementally (which is mostly normal). Yet, on the surface, this may come across as confusing.

4. They make situations worse by trying to suppress their feelings about them. They are extremely uncomfortable with other people seeing them in pain, and they don’t want to feel pitied or as though they are compromising anyone’s time. Yet, they make things worse for themselves by suppressing, as it actually funnels a ton of energy into making the problem larger and more present than it already was.

5. They are often hyper-aware and highly intuitive. Anxiousness is an evolutionary function that essentially keeps us alive by making us aware of our surroundings and other people’s motives. It’s only uncomfortable when we don’t know how to manage it effectively – the positive side is that it makes you hyper-conscious of what’s going on around you.

6. Their deepest triggers are usually social situations. It’s not that they feel anxious in an airplane, it’s that they feel anxious in an airplane and are stuck around 50 other people. It’s not that they will fail a test, but that they will fail a test and everyone in school will find out and think they are incompetent and their parents will be disappointed. It’s not that they will lose love, but that they will lose love and nobody will ever love them again.

7. It is not always just a “panicked feeling” they have to hide. It can also be a tendency to worry, catastrophizing, etc. The battle is often (always?) between competing thoughts in their minds.

8. They are deep thinkers, and great problem-solvers. One of the benefits of anxiety is that it leads you to considering every worst case scenario, and then subsequently, how to handle or respond to each.

9. They are almost always “self-regulating” their thoughts. They’re talking themselves in, out, around, up or down from something or another very often, and increasingly so in public places.

10. They don’t trust easily, but they will convince you that they do. They want to make the people around them feel loved and accepted as it eases their anxiety in a way.

11. They tend to desire control in other areas of their lives. They’re over-workers or are manically particular about how they dress or can’t really seem to let go of relationships if it wasn’t their idea to end them.

12. They have all-or-nothing personalities, which is what creates the anxiety. Despite being so extreme, they are highly indecisive. They try to “figure out” whether or not something is right before they actually try to do it.

13. They assume they are disliked. While this is often stressful, it often keeps them humble and grounded at the same time.

14. They are very driven (they care about the outcome of things). They are in equal proportions as in control of their lives as they feel out of control of their lives – this is because they so frequently try to compensate for fear of the unknown.

15. They are very smart, but doubt it. A high intelligence is linked to increased anxiety (and being doubtful of one’s mental capacity are linked to both).

Trosku obsirnejsi clanok o cinskom satelite na kvantovu komunikaciu.

Je tam ale jedna pasaz ktorej nerozumiem - pisu ze posielaju redundantne pary kvantovo previazanych fotonov lebo su velke straty kvoli zrazkam s atmosferou. Ako potom zistia ci sa im foton zrazi so vzduchom a par kvantovo skolabuje, alebo ci im ho niekto odchytil a preto par kvantovo skolaboval?

1. Materials with Negative Poisson’s Ratio
Materials with a positive Poisson’s ratio contract when stretched, but those with a negative ratio actually expand when stretched, and while rare metamaterials are being engineered to create materials that possess this property of expanding when stretched This review article digs into the negative Poisson’s ratio materials that already exist as well as laying out avenues for exploring ever better materials with beneficial mechanical properties such as shear resistance, indentation resistance, and fracture toughness. I’d even just like to play with a strip of this stuff.

2. IBM’s Latest Lab on a Chip
IBM’s latest microfluidic lab on a chip devices are capable of size-based separation of biological particles down to 20nm, a scale that allows DNA, viruses, and cellular exosomes to be separated out Working with researchers they are examining exosome communication and signalling between cells, and working with clinicians they are using the new capability in a similar way to diagnose cancer and other diseases. The architecture of the device allows variable particle separations under continuous flow and can actually split a mixture of many different particle sizes into a spread of defined particle streams, analogous to a prism splitting light. Meanwhile other microfluidic systems are replicating the connections between neurons and muscle fibers

3. IBM’s Latest Neuromorphic Computing Device
IBM’s latest brain-like computing hardware has demonstrated chips that produce spiking neuromorphic features using phase-change materials to store and process data IBM’s phase-change technology platform has already demonstrated novel memory techniques, but these new neuromorphic applications can perform data correlation detection and also unsupervised learning at high speed and low energy; updating these phase-change neurons requires just five picojoules. When will we start to see these things appearing in robots?

4. Single Pixel Camera Advances
The latest advance in computational photography using single-pixel cameras now enables single-pixel camera devices to not only produce human-like foveated images in which the center is captured in high-resolution and periphery in low-resolution, but can now also move this foveated region around to follow objects in the field of view The system can produce two moveable foveated regions, works in visible and infrared, and might enable applications in terahertz imaging for which single pixel sensors are available and arrays are not, as well as allowing conventional trade-offs between resolution and framerate to be optimised on the fly for general imaging systems.

5. One Dimensional Magnetic Atom Chains
That’s a headline I didn’t expect to write this side of 2020. By combining a process of evaporating metals onto a surface with the controlled introduction of oxygen, one dimensional magnetic atom chains bordered by oxygen can now be created, and all via a process of self-assembly Metals explored as part of the proof-of-concept include Mn, Fe, Co, & Ni. The atom chains cover the entire surface, space 0.8nm apart, and up to 500 atoms long without a single structural defect. In the new one dimensional state the different metal atoms exhibit altered magnetic properties including non-magnetic, ferromagnetic, & anti-ferromagnetic. Such structures may have applications in high-density data storage but the advance will be a boon to studying and controlling one dimensional systems in general.

6. On-Chip LIDAR Systems
Recent advances in developing on-chip LIDAR systems for 3D mapping and ranging local environments using conventional semiconductor fabrication techniques look set to produce complete LIDAR systems smaller than a dime at less than $10 per unit While not only being orders of magnitude smaller than conventional systems, and orders of magnitude cheaper, the devices have 1,000 times faster image scanning. There is a roadmap to boost field of view from 50 to 100 degrees, from 2m to 10m soon and 100m later in range, and further boosting resolution. These systems are going to be absolute game changers for autonomous vehicles, robots, drones, and our smart devices generally, massively boosting their ability to move about in the real world. Spectrum shared a big drone sporting big LIDAR system navigating a barn this week, as part of

7. Smarter Bots Fix Malicious Code
New machine learning approaches are able to search hacker marketplaces and other hidden parts of the Web to help find and identify zero day exploits and other critical software vulnerabilities in order to drastically improve the ability of organisations to fix broken code and distribute patches before they can be exploited In related news DARPA’s Grand Cyber Challenge continues to encourage the development of ever-better software systems able to quickly find and fix a range of different software bugs better than human teams can

8. Spider Bots Monitor Airships
Lockheed Martin has developed a SPIDER bot platform that involves groups of robots that move around and inspect the skin of an airship for tiny pinholes that are difficult for humans to detect, which can then be quickly patched and sealed to prevent the leakage of Helium While this is a prototype autonomous inspection and repair system that should contribute to airship safety and cost reduction, the team hope that further development will allow such systems to function in-flight as needed in a range of conditions.

9. Resistant Productive Microbial Fermenters
To combat the problem of undesirable contaminant microbes growing in fermenters and bioreactors with productive microbes and so serving to decrease and contaminate yields, productive microbes are being engineered to be able to extract the vital growth nutrients nitrogen and phosphorous from unconventional xenobiotic compounds In some cases this involved the addition of six genes to provide the enzymatic processing network needed to extract nutrients from the xenobiotic compounds; contaminant microbes lacking these pathways are unable to use the nutrients and are massively outcompeted by the productive microbes.

10. Novel Electrical Materials
Some interesting new electrical materials and devices this week. First, nanoparticles of topological insulators appear to provide a platform for strong coupling between a single photon and a single electron that could be useful for photonics and optoelectronics in future Second, a layer of buckyballs proves important in creating tiny on-chip diodes that conduct electricity 1,000 times more effectively on one direction as opposed to the other Third, graphene appears to facilitate a novel property of electrons called pseudospin Finally, the ability to create and manipulate two-dimensional sheets of silicon, or silicene, for electronics applications takes a major step forward

1. Writing Data Atom by Atom
A scanning tunneling microscope has been used to produce re-writable data storage by positioning arrays of individual chlorine atoms in one of two defined positions (representing 0 or 1) The prototype successfully stored 1 kilobyte of data or 8,000 bits on a copper surface, and achieved a storage density of 500 Terabits per square inch. The array is organised into blocks of 64 bits but requires very clean vacuum conditions and liquid nitrogen temperatures to work. Still, a very impressive proof of concept.

2. Advances in Imaging Technology
First, new nuclear magnetic resonance microscope comprises a very thin wire connected to a tiny magnetic ball is able to achieve an imaging resolution of less than 10nm, a 100-million fold improvement in the volume resolution of bulk NMR Second, a new technique for energy-filtered transmission electron microscopy is now claiming subatomic resolution and the ability to obtain clear images of electron orbitals within an atom . . . which is a headline I never expected to see for a long time to come. Finally, manipulation of plasmonics on surfaces now allow optical microscopes to perform like electron microscopes with 65nm resolution

3. One-Dimensional Transistors
By studying two-dimensional atomically-thin transistors made out of molybdenum disulfide a group has discovered that just the edges of the device, which are essentially one-dimensional, might be used as a transistor The current flowing through the device starts first (at very low voltages) by flowing along the edge, and only leaks into the middle of the device as the voltage is boosted to much higher levels; by making purer, defect-free devices the edges should be able to carry the entire current - meaning the bulk of the device isn’t needed and transistor switching requiring much lower power.

4. DARPA’s Modular Chiplets
A new DARPA program aims to reimagine the standard printed circuit board as a modular integrated platform that not only allows further miniaturisation and speed improvements, but also provides standard lego-like size and architecture specifications for which specialised chiplets are able to be dropped into in order to perform some desired electronic or computational function I think of this as Project Ara for integrated circuits: instead of swapping mobile phone components into a standard platform, this program will allow the rapid design of complete circuits with chiplets for sensing, processing, memory, ASICs, GPUs, antennas, signal processors, etc, all while getting around the main limitations of PCBs.

5. New Drone Tops 70mph
A new consumer quadcopter drone called Teal is set to become the fastest available with a top speed of 70mph and stability in winds up to 40mph Boasting a teraFLOP of onboard processing power for machine learning, autonomous flying, image recognition, the group hope to include obstacle avoidance in the near future. The GPS system on board enables 50cm positional accuracy. Of interest: Teal is designed to enable programmers to easily create Apps that make use of or control Teal. Also included this week due to the comment discussion on the linked page - worth a read and serious consideration.

6. Synthetic Biology Programs Compute Stimuli
Another important step in the development of synthetic biology, cells can now be programmed to remember and respond to a series of events This is a scalable system with the proof-of-concept creating cells that can remember the correct order of three different inputs, and which might allow the recording of complex cell histories. These are like biological state machines. “These recombinase-based state machines open up the possibility of cells being engineered to become recorders of temporal information about their environment, and they can be built to lead the cells to take actions in response to the appropriate string of inputs.”

7. Most Detailed Brain Map Ever
A new MRI measurement study, part of the Human Connectome Project, and using scans of 210 different healthy human brains has produced the most accurate cortical brain map ever The map identifies 180 distinctly different areas of the cortex, which include 83 previously reported brain areas and 97 new ones. The scans themselves collected data across a range of variables including cortical thickness, brain function, regional connectivity, cellular topographic organisation, and levels of myelin and it was well defined differences between this factors that helped delineate one area from another.

8. Tactile Intelligence and Robotic Grasping
This is a good overview of the state of the art and future developments expected for robotic grasping facilitated by tactile intelligence rather than vision and various visual-grasping intelligence approaches After discussing some of the shortfalls of focusing exclusively on vision for grasping we get a presentation of the new CoRo Lab tactile grasping system that combines a robotic hand, UR 10 arm, multimodal tactile sensors, and a kinect for initial targeting that can predict grasp failure 83% of the time and predict object slippage 92% of the time. Both are complex and are facilitated by unsupervised machine learning algorithms that learn over many trials what signal features are important. Such a system would also be very applicable to prosthetics.

9. Placenta on a Chip
Continuing the development of organ-on-microfluidic chip technology we now have a very basic placenta on a microfluidic chip that fully models the transport of nutrients across the placental barrier While this and other organ on chip systems are initially being developed as research and drug development tools, with thoughts of future advances enabling artificial organs, in this case such an artificial placenta hints at the future ability to build artificial wombs. In related reproductive health advances menopause can now be reversed to restore periods and produce viable eggs

10. Injectable Biosensors & Oxygen
A couple of interesting injectable treatments or enhancement technologies this week. First, a DARPA sponsored project has produced an injectable, implantable biosensor made of hydrogel that can produce a different fluorescent signal when different molecules are present, and which also overcomes the immune rejection problem Second, tiny gas-filled lipid microparticles have been developed as an injectable oxygen substitute that in tests was able to keep organs oxygenated and keep animals alive for 15 minutes without taking a single breath Reminds me of a basic, dumb precursor to respirocytes that would enable enhanced athletic performance across a range of measures and activities.

1. DNA Framework for Nanostructures
DNA origami techniques are being used to form precisely structured, self-assembled nanoparticle lattices with custom architectures The technique is based on forming modular lego-brick-like frames made of DNA that bind nanoparticles in the center of the frame and then link to other frames in precise orientations and positions, allowing custom 3D lattices to be formed as desired. There are very interesting possibilities here in forming interesting materials for optics (metamaterials), electronics, and other applications. In related news, precise modular molecular construction is becoming ever more sophisticated and

2. Machine Learning Advances
An interesting trio of machine learning applications this week. First, we have the demonstration of a system able to take a rough sketch (of a face for example) and generate a photo-realistic image as an output Second, a dashcam app for cars that tracks other cars on the roads, rates their driving, and warns users of dangerous or erratic drivers when nearby and which has interesting insurance and other implications Finally, a system that can perform accurate eye-tracking using just a smartphone camera and which should open up eye-tracking tools and applications for developers generally

3. Brain Structure Insights
A work shows why hierarchical networks appear so often in biology and particularly govern neurons in the brain Hierarchical networks contain fewer connections and the connections themselves - synapses in the case of the brain - are biologically expensive to build and maintain and so are ultimately driven by energy optimisation concerns. Such insights are expected to feed into designing better artificial neural networks. In related news birds turn out to have a much higher density of neurons in their brains, particularly the forebrain, compared to other animals including primates and in some cases match or exceed primate neuron counts, which helps to explain the intelligence exhibited by some bird species

4. Improving the Effectiveness of Gene Drives
It turns out the current gene drive technology, of ensuring that particular genes are carried throughout a population over many successive generations, and offering the possibility of wiping out traits or whole species, are imperfect and suffer from the evolution of resistance to their effects. Second and third generation gene drive technology is under development however that is far more sophisticated and designed to avoid this evolution of resistance and ensure traits are passed down or local populations of species wiped out regardless of attempts to evolve resistance

5. Never Ending Graphene Wonders
First, graphene is being used to produce and control a form of Cerenkov Radiation, in which light hitting the graphene surface is slowed to a point at which electrons travelling along the surface exceed the speed of light and produce a different burst of electromagnetic radiation Second, tiny graphene “drums” beating at 100Mhz might be used as highly sensitive mass detectors Third, graphene nanoribbons can now be fabricated wafer-scale in suspended non-contact structures Finally, another straintronics approach, squeezing graphene can control heat conduction through the material

6. Metagenomic Cross Genome Analysis
A metagenome is the total DNA content from many different microorganisms that inhabit the same environment, for example in the human gut. MetaFast is a new piece of software developed to quickly analyse and compare different metagenomes from both similar and different environments For example, MetaFast might quickly compare the metagenomes of the gut microflora from both healthy and unhealthy patients and feed this into personalised medicine applications, or otherwise rapidly characterise a person or environment as healthy or unhealthy, even without knowing the exact identity of all of the microorganisms being considered.

7. Opening Blood Brain Barrier with Pulsed Ultrasound
In recent work the blood brain barrier can be temporarily opened by using focused pulsed ultrasound to vibrate stabilised (but short-lived) microbubbles that have been injected into the bloodstream One of the current drawbacks is that the ultrasound device must be placed inside the skull; however in clinical trials the technique was able to deliver five times the amount of a cancer drug into the brain to treat glioblastoma tumours than would otherwise be possible. Such a platform, with further improvements, might be widely applicable to a range of brain and CNS treatments and interventions.

8. Phase-Locked Microlaser Arrays
A single-chip monolithic array of 37 microfabricated laser antennas produces one of the most advanced terahertz light sources created Each antenna is coaxed to phase-lock with its neighbours to produce a combined light source that is all in-phase, while lateral emissions are recaptured and re-emitted perpendicular to the array to form a very tight terahertz beam source with very low energy requirements. This is another important step in terahertz technology, bringing it closer to real world applications in security and medical diagnostics.

9. Sensors Invisible to Electronic Inspection
Sensors have been rendered invisible to thermal and electrical inspection with a new type of thin copper shell that mimics local thermal and electric fields, while still allowing the enclosed sensor to perform its function and receive appropriate signals from the outside Such a technology not only has important applications in the security and surveillance space, but also for sensing systems forced to operate in high voltage or high temperature environments.

10. Replacing and Boosting Stem Cells
It appears that most current stem cell treatments don’t involve the introduced cells integrating with target tissues, but rather temporarily alter the local stem cell niche and signalling environment to spur healthy activity in surrounding cells. More recent work is starting to achieve more permanent integration however, particularly with neural stem cells in neurodegenerative disorders Also, improved techniques for reprogramming adult stem cells appear to produce cells that are indistinguishable from embryonic stem cells
