Cure Pregnancy Problems Fast



Having problem conceiving? Have you gone to the doctor but found no viable solution for what you’re going through? Are you tired of having to hear one disappointing news after another? This is an experience of many. In the U.S alone, 10% of married couples are trying to cope with infertility. Advancement in technology has allowed Western medicine to come up with sophisticated infertility treatments like In Vitro Fertilization (IVF) and Intrauterine Insemination (IUI) but they’re barely affordable even for the more well-off couples. Additionally, the chances of succeeding at conceiving using these infertility cures are low. These technologies are invasive. I am a firm believer in natural treatments; that they’re always the best solution. Pregnancy Miracle by Lisa Olson is one book that deals with infertility naturally so I highly recommend it.
Pregnancy Miracle’s goal is to treat infertility in the most natural way possible. Books of this kind usually involve steps that follow TCM or Traditional Chinese Medicine. Pregnancy Miracle’s premise is that the body, when in an imbalanced state, would have a hard time priming up for conception. Increase your chances of conceiving significantly by bringing your body back to its balanced state. In fact, this infertility treatment has a high success rate than any other forms. I would recommend going for options like Pregnancy Miracle and The Personal Path to Pregnancy by Beth Kiley first before choosing to go for Western infertility treatments.
Even though Western fertility treatments are popular, you can’t discount the fact that they have disadvantages and that you should take it upon yourself to know them. Consider Cycloid, for instance. It’s arguably the most preferred fertility treatment for the following reasons: You orally take it so it’s simple to employ. Two, it’s the solution for the most common cause of infertility, ovulation. Three, it seems to be the safest out of all fertility treatments as its side effects are lesser than the rest. Four, it is relatively less expensive than IVF and other infertility solutios. But even as a safe pill, taking too much Cycloid can create irreversible damage to your uterus and your cervical mucus. It could give you a thin uterus wall and a cervical mucus that cannot accommodate sperms because it might be too hostile of an environment for them. So while fertility drugs may be the first recommendation of many doctors, it is simply far better to back out on them and go for TCM-based treatments instead.

What is Inside of E-Cigarette Cartridges?



An e-cigarette or electronic cigarette is a specialized unit that’s purposely intended to be an alternative way of providing doses of nicotine to the smoker. By heating up the contents of the cartridge of the e-cigarette, transforming it directly into vapor, that’s after that taken in by the smoker. The electronic tobacco cigarette gadget consists of different parts that works collectively to imitate the way the conventional cigarette functions and is used by a smoker.
Very different from normal tobacco cigarettes available today, the e-cigarette doesn’t only use high tech parts, it’s supply of nicotine is very different to ordinary cigs. Rather than using the tar as well as the leaves from the tobacco plant to derive the nicotine, which is a highly addicting ingredient, the e-cigarette has cartridges used to keep the liquid nicotine that’s going to be vaporized and then converted to a mist.
There are a few types of e-cigarette cartridges that also have a built in atomizer or heating system gadget. A brand new permanent atomizer is expensive. Naturally, this kind of cartridge for the e-cigarette could have a moderately higher price tag compared to normal cartridges nevertheless, it may provide you with significant personal savings in the long term, as there won’t be a need to buy a brand new one. Operating as the mouthpiece for the entire gadget is the e-cigarette cartridge. This particular section of the e-cigarette cartridges also provides a tube like filter similar to a tobacco cigarette end. The e-cigarette cartridges use a sensor that is also run via the battery that detects when the user would like to breathe in a bit of vapor thereby initiating the atomizer to heat up the fluid nicotine within the holding chamber. The vapor that will come out via a different tube coming out of the unit is then able to be inhaled by the e-cigarette smoker.
In an effort to help make the entire e-cigarette smoking experience more like smoking cigarettes a conventional cigarette, some manufacturers build in LED lights on the end of the unit, near the mouthpiece, which lights up once the end user inhales smoke from the unit.
The liquid nicotine that is enclosed inside the e-cigarette cartridges is commonly created from vegetable glycerin or propylene glycol. These types of compounds are commonly seen in a few processed foods sold in the market today because it is permitted for use as a food preservative. The compounds are combined with a calculated measure of the nicotine, thereafter they’re placed in the cartridges of the e-cig. It is possible to make use of a nicotine free version of e-cig cartridge. This is especially very important to individuals wanting to stop smoking but who want to continue the sense of using cigarettes.

Bats adjust squeaks to focus sonar


Human eyes, set as they are in front-facing sockets, give us a limited angle of view: we see what is directly in front of us, with only a few degrees of peripheral vision. But bats can broaden and narrow their 'visual field' by modulating the frequency of the squeaks they use to navigate and find prey, researchers in Denmark suggest today in Nature1.
Bats find their way through the night by emitting sonar signals and using the echoes that return to them to create a map of their surroundings — a process called echolocation. Researchers have long known that small bats emit higher-frequency squeaks than larger bats, and most assumed that the difference arises because the smaller animals must catch smaller insects, from which low-frequency sound waves with long wavelengths do not reflect well.
That didn't sound right to Annemarie Surlykke, a neurobiologist who studies bat echolocation at the University of Southern Denmark in Odense. “When you look at the actual frequencies, small bats would be able to detect even the smallest prey they take with a much lower frequency,” she says. “So there must be another reason.”
Surlykke and her colleagues decided to test the hypothesis by studying six related species of bat that varied in size. They captured the animals in the wild and set them loose in a flight room — a pitch-dark netted corridor 2.5 metres high, 4.8 metres wide and 7 metres long, rigged on all sides with microphones and infrared cameras. “It’s a pretty confined space, so this corresponds to flying close to vegetation,” says Surlykke.

Direct call

By measuring the time it took for a bat’s echolocation signals to hit different microphones, Surlykke’s team could pinpoint the exact location of the animals in flight. They could then analyse the intensity of each signal, as well as the size of each animal’s mouth, to reconstruct the width of the sound beam.
Under the specific conditions of the flight room, the researchers found, the animals adjusted the frequency of their signals and the openings of their mouths to come up with the same beam width for their echolocation calls — around 37°, no matter the animal's size. In past studies, two species tested in the field used different beam widths depending on whether they were scanning for prey from on high or about to dive in for the capture.
“That means that the small bats, we think now, are not forced to use the high frequency to detect their prey, but to keep the beam narrow,” says Surlykke. A lower-frequency vocalization would broaden the beam, making it hit more objects and increase the noise in the signal, which would make echolocation more difficult. So small species need to use high frequencies simply because their mouths are petite.

Out and about

Hans-Ulrich Schnitzler, who studies echolocation at the University of Tübingen in Germany, lauds the finding for bringing a previously unconsidered parameter to the discipline. “I really think it opens up a new field,” he says.
However, he thinks that the group’s conclusion is not yet definitive. “It now has to be documented for other species and for flying out in nature — in the open, in the forest, in different habitats,” says Schnitzler.
Surlykke notes that her group examined only bats that echolocate using their mouths. “One of the intriguing questions is how this works in nose-emitting bats,” she says.

The study raises the question of how bats perceive their environment, says Surlykke, and her group plans to look at this too.
“The fact that the beam is constant means the important thing is in the bat’s head — and not in the environment,” says James Simmons, a neurobiologist at Brown University in Providence, Rhode Island. “Ultimately,” he says, “it’s a psychological problem.”

MicroRNAs 103 and 107 regulate insulin sensitivity

Defects in insulin signalling are among the most common and earliest defects that predispose an individual to the development of type 2 diabetes123. MicroRNAs have been identified as a new class of regulatory molecules that influence many biological functions, including metabolism45. However, the direct regulation of insulin sensitivity by microRNAs in vivo has not been demonstrated. Here we show that the expression of microRNAs 103 and 107 (miR-103/107) is upregulated in obese mice. Silencing of miR-103/107 leads to improved glucose homeostasis and insulin sensitivity. In contrast, gain of miR-103/107 function in either liver or fat is sufficient to induce impaired glucose homeostasis. We identify caveolin-1, a critical regulator of the insulin receptor, as a direct target gene of miR-103/107. We demonstrate that caveolin-1 is upregulated upon miR-103/107 inactivation in adipocytes and that this is concomitant with stabilization of the insulin receptor, enhanced insulin signalling, decreased adipocyte size and enhanced insulin-stimulated glucose uptake. These findings demonstrate the central importance of miR-103/107 to insulin sensitivity and identify a new target for the treatment of type 2 diabetes and obesity.

Hubble Eyes a Loose Spiral Galaxy


The galaxy is viewed from an angle, allowing Hubble to reveal its spiral nature clearly. The faint, loose spiral arms can be distinguished as bluish features swirling around the galaxy's nucleus. This blue tinge emanates from the hot, young stars located in the spiral arms. The arms of a spiral galaxy have large amounts of gas and dust, and are often areas where new stars are constantly forming.
The galaxy's most characteristic feature is a bright elongated nucleus. The bulging central core usually contains the highest density of stars in the galaxy, where typically a large group of comparatively cool old stars are packed in this compact, spheroidal region.
One feature common to many spiral galaxies is the presence of a bar running across the center of the galaxy. These bars are thought to act as a mechanism that channels gas from the spiral arms to the center, enhancing the star formation.
Recent studies suggest that ESO 499-G37's nucleus sits within a small bar up to a few hundreds of light-years along, about a tenth the size of a typical galactic bar. Astronomers think that such small bars could be important in the formation of galactic bulges since they might provide a mechanism for bringing material from the outer regions down to the inner ones. However, the connection between bars and bulge formation is still not clear since bars are not a universal feature in spiral galaxies.
The galaxy ESO 499-G37 lies in the southern border of the constellation of Hydra, which is shared with Antlia.
ESO 499-G37 was first observed in the late seventies within the ESO/Uppsala Survey of the ESO (B) atlas. This was a joint project undertaken by the European Southern Observatory (ESO) and the Uppsala Observatory, which used the ESO 1-metre Schmidt telescope at La Silla Observatory, Chile, to map a large portion of the southern sky looking for stars, galaxies, clusters, and planetary nebulae.
This picture was created from visible and infrared exposures taken with the Wide Field Channel of the Advanced Camera for Surveys. The field of view is approximately 3.4 arcminutes wide.

Single photon could detect quantum-scale black holes


Space is not smooth: physicists think that on the quantum scale, it is composed of indivisible subunits, like the dots that make up a pointillist painting. This pixellated landscape is thought to seethe with black holes smaller than one trillionth of one trillionth of the diameter of a hydrogen atom, continuously popping in and out of existence.
That tumultuous vista was proposed decades ago by theorists struggling to marry quantum theory with Einstein’s theory of gravity — the only one of nature’s four fundamental forces not to have been incorporated into the standard model of particle physics. If it is true, the idea could provide a deeper understanding of space-time and the birth of the Universe.
Scientists have attempted to use the Large Hadron Collider, gravitational wave detectors and observations of distant cosmic explosions to determine whether space is truly grainy, but results have so far been inconclusive. Now, Jacob Bekenstein, a theoretical physicist at the Hebrew University of Jerusalem, has proposed a simple tabletop experiment to find out, using readily available equipment1.
As in previous experiments, Bekenstein’s set-up is designed to examine the problem on the scale of 1.6 × 10−35 metres. This 'Planck length' is thought to mark the scale at which the macroscopic concept of distance ceases to have meaning and quantum fluctuations begin to cause space-time to resemble a foamy sea.
No instrument can directly measure a displacement as small as 1035 metres. Instead, Bekenstein proposes firing a single particle of light, or photon, through a transparent block, and indirectly measuring the minuscule distance that the block moves as a result of the photon’s momentum.

Light and mass

The wavelength of the photon and the mass and size of the block are carefully chosen so that the momentum is just large enough to move the block’s centre of mass by one Planck length. If space-time is not grainy on this scale, then each photon will pass through the block and be recorded by a detector on the other side. However, if space-time is grainy, the photon is significantly less likely to make it all the way through the block. “I argue that the consequence of that crossing — the translation of the block by a Planck length or so — is something nature would not like,” says Bekenstein.
If quantum fluctuations in length are important on the Planck scale, a sea of black holes, each with a Planck-scale radius, will readily form. Anything that falls into one of those black holes will be unable to escape until the hole disappears. So if the centre of mass of the moving block falls into one of the holes, the block's movement will be impeded (the photons are much larger than the Plank length, and so are not bothered by the miniature black holes).
Conservation of momentum in the experimental set-up requires that the photon cannot make it through the block if the block fails to move by a Planck length. So if fewer photons than expected are seen by the detector, it would indicate that the block's movement has been impeded by black holes, and that space-time exhibits quantum features at the Planck scale.
Bekenstein’s design is simple, so the experiment could easily be put into practice using established methods of generating and detecting single photons, says Igor Pikovski, a quantum physicist at the Vienna Center for Quantum Science and Technology. Nevertheless, he adds, “distinguishing possible quantum gravitational effects from other effects will be very challenging”.
Earlier this year, Pikovski and his colleagues published2 another scheme for probing the graininess of space-time in the laboratory, using optical pulses and and the principles of quantum theory to drive a system from an initial configuration to the desired final state. “The truth is that we do not know at what exact scale quantum gravity will play a significant role,” says Pikovski. “There is plenty of room for granularity at much larger lengths [than the Planck length] and we do not have a full theory that could tell us the answer.” Experiments such as Bekenstein’s or his own may provide some of the first evidence for an answer, he adds.
