![]() Eventually, it is possible that we will develop economically viable means for sucking carbon out of the atmosphere and burying it in the Earth. Ruan’s white paint can play a role in cutting temperatures, as can techniques for reducing the acidity of the ocean and increasing its absorption of CO2. In any case, there is simply no way to improve climatic conditions, rather than merely constraining their degradation, without some form of geoengineering. But they are (almost certainly) less hazardous than tolerating more than 1.5 degrees Celsius of warming above preindustrial levels. Consciously manipulating the reflectivity of the Earth’s surface and atmosphere, or the alkalinity of its oceans, are risky endeavors. Nevertheless, Ruan’s invention calls attention to the fact that humanity has the capacity to not just mitigate future warming, but actually reduce global temperatures through feats of engineering. Relying exclusively on reflected sunlight to compensate for the greenhouse effect would be perilous. Rather, you would need to distribute giant expanses of white paint at strategic locations around the planet.Įven if humanity could execute such a quixotic plan, doing so still wouldn’t actually obviate the need for decarbonization. And you wouldn’t actually want to concentrate such paint in a single contiguous area, as this would have severely disruptive implications for the regional climate. You would therefore need to cover a land mass roughly the size of the United States in ultrawhite paint in order to stop the planet from absorbing more heat than it emits and stabilize global temperatures. After all, 71 percent of the Earth’s surface is water. Of course, this is not an especially practical proposition. The substance redirects so much light and heat back into space that, according to one calculation, it could offset the impact of ongoing carbon emissions if we could somehow pour it over 1 to 2 percent of the entire planet. More stunning than these local effects are the paint’s potential global ones. Such paint would thereby enable that building to use up to 40 percent less air-conditioning to achieve the same internal temperature. Now, Ruan’s team has engineered a shade that reflects 98 percent of sunlight.Ĭover a building in Ruan’s white paint, and you’ll render its surface eight degrees cooler than the air temperature by day, and 19 degrees cooler by night. ![]() A researcher at Purdue University, Ruan has spent years trying to develop a maximally reflective type of white paint, one that could bounce upwards of 95 percent of the sun’s rays off of any given surface and then back out into deep space, cooling the planet in the process. This week, the New York Times reported on Xiulin Ruan’s extraordinary feat of pigmentary engineering. Unless we just need to dump 139 billion gallons of extremely white paint across roughly 2 percent of the Earth’s surface. We must build vast constellations of wind and solar farms, lace continents with high-voltage transmission lines, replace all internal combustion engines with batteries, decarbonize heavy industry, increase the energy efficiency of our buildings, expand mass transit, and promote housing density, among myriad other things. To stabilize global temperatures, humanity needs to replace the energy basis of industrial modernity. Photo: Bing Guan/Bloomberg via Getty Images

This allows the user to capture more vivid and brilliant images, regardless of the environment they are shooting in, in real-time.Īlthough the Galaxy S5 also had live-HDR, the Galaxy S6 and S6 edge have this feature in both the front and rear cameras. The Samsung Galaxy S6 and S6 edge will feature a powerful, real-time HDR function in both the front and rear camera, an unprecedented achievement in smartphone camera technology. In addition, HDR could not be incorporated into video recordings during early adaptations, due to the complexity of real-time lighting comprehension. Incorporating HDR into smartphone cameras is not new, however, the HDR image took a while to be created as several separate images had to be edited together. Typically, multiple images consisting of high, low and mid exposures are required to create an HDR image. HDR combines a series of high-exposure and low-exposure images to find the perfect balance, creating an effect similar to the human eye. High Dynamic Range (HDR) is a powerful photographic tool that allows the photographer to capture the richest and most vibrant colors from both their environments and subjects. With the Galaxy S6 and S6 edge, taking pictures with the front camera will rival the quality of the main camera in most other smartphone models. With a larger image sensor, a clearer picture can be captured and easily adapted to any media, keeping the quality of shared images high. The Galaxy S6 and S6 edge’s front camera also contains a CMOS camera image sensor that is 1.4 times larger than its predecessor. Now boasting a 5MP camera that supports wide-angle images and an enhanced beauty mode – capturing the perfect Wide Selfie shot has never been this easy, or rendered so beautifully. Some of the more notable camera improvements in the new Galaxy S6 and S6 edge can be found in the front camera. With this in mind, Samsung has greatly improved both the quality and usability in the front and rear cameras of the Galaxy S6 and S6 edge to achieve pictures that more closely simulate how the human eye sees the visible world a first in smartphone camera technology. Samsung has been at the forefront of smartphone camera innovation and technology, and this year’s flagship model was no exception. ![]() Users are constantly requiring features that can be more easily tailored to their photographic needs. Of course there is always Beastgrip and other universal "cages", but those are quite bulky.Consumer habits around smartphone camera usage have been drastically increasing – and there are no signs of slowing down. It has killer cameras and the 108mp sensor would lend itself so well to a slick case-integrated adapter of external lenses. So yeah, my question is if there are any users of these previous products here and what they think of the prospects of properly designed addon lenses and threaded cases for the S22U. Ulanzi, same story, but I haven't found anything specific about S22, it's a Chinese company from what I gather so it's harder to get info, it's all a bit muddy. Moment still sells lenses and lens-compatible cases for S20/21 and some late Pixels and Onepluses, but they apparently didn't think it was profitable to do so for the S22 series. Moment decided to focus on Apple phones from now on, as their Apple-exclusive main competitor Sandmarc does. I realize this is a question that detracts from the software-oriented scope of this forum but I wanted to ask if any users of previous Galaxy S20 and 21 phones ever used these addon lenses (that come with dedicated cases with threads for 17mm or Moment's proprietary lens/filter mount, easy unobtrusive on the fly switching and looking heaps better than those ugly clip-ons). ![]() These frogs just lay over the mud of the bottom of the water. Since the aquatic frogs can not survive without water, these frogs hibernate at the bottom of the water body. Aquatic Frogs Hibernating PlaceĪlthough the terrestrial frogs get burrowed in hibernation, the aquatic frogs do not hide below the mud. You can also check out this article if you are curious about other reasons for frogs burrowing. Not to mention, these frogs follow the method of burrowing themselves to hibernate in the winter. Usually, the land-dwelling frogs or terrestrial frogs burrow themselves down under the frosting line of the forest. ![]() It depends on the species and types of frogs. Since frogs enter into hibernation during winter, they choose suitable places to stay over. For this reason, people do not see frogs in the winter months. Some frogs burrow under leaf litter during hibernation.īesides, the aquatic frogs spend the winter hibernating at the bottom of the water sources. So, some of these frogs remain burrowed below the frost line. To cope with the low temperature, frogs go into a hibernation state. When the temperature falls, frogs can not continue their regular activities. It means these amphibians depend on external sources to regulate their body temperature. You must be aware of the fact that frogs are cold-blooded animals. Usually, frogs break their hibernation state in spring. On the other hand, these frogs come out of hibernation when the temperature rises. So, frogs hibernate in winter when the temperature goes below freezing point. When the temperature falls, the activity of the frogs’ body goes into a resume state called hibernation. ![]() Since frogs can not regulate their body temperature, it becomes hard to survive in cold weather. Also, researchers found ice to be formed in the frog’s body cavity during winter. Although the vital organs of frogs remain protected, around more than 65% of the water in frogs’ bodies will freeze.Įspecially, aquatic frogs are not freeze-tolerant. It works as an anti-freeze protein and prevents the vital organs from freezing.īut, there is complexity too. A high concentration of glucose gets produced in the liver of frogs. Although they look frozen and dead outside, the internal body activities go on at a slower rate.įrogs do not get frozen in the winter. People might wonder why frogs do not get frozen, being ectothermic animals. Anti-freezing: Do Frogs Freeze In The Winter? In addition, if you’re curious about frogs breathing, you can check our article: how long can frogs hold their breath? 4. Moreover, frogs absorb water through the skin as they breathe during hibernation. So, frogs need not be active to breathe through nostrils in cold winter.īut, if the frog’s skin becomes dry, it will fail to breathe oxygen through the skin. Further, the oxygen gets passed to the body cells of the frog body.įor this, frogs need to choose the oxygen-riched area to hibernate where their skin also remains damp. They can filter the oxygen from the water and pass it through the vessels in the skin. You might know that frogs have specially designed permeable skin. But, all frogs breathe through their skin via cutaneous respiration when they hibernate.Īlmost all frogs continue to breathe the entire period of hibernation except a few frogs like the wood frog. Generally, frogs can breathe through their gills, lungs, and skin. Breathing Through Skin: How Do Frogs Breathe When They Hibernate? So, frogs utilize their stored body fats and energy slowly in this way.ģ. However, there remains a shortage of insects in winter. This slowing down of regular activities helps them save up their energies without ingesting foods.Īlso, frogs can not get out for hunting in cold temperatures. Not to mention that frogs slow down their respiratory rate, heart rate, and body temperature to survive the winter. As these frogs slow down their metabolic rate, they stop their movement, consuming foods, drinking, and other activities. The significant change in frogs is their slower metabolism during hibernation. Since frogs hibernate to survive in winter, they go through some physical and behavioral adaptations. You might assume a hibernating frog is a dead frog. During this hibernation period, frogs’ bodies go through dramatic changes that help them cope with the temperature fall. It is a common response for all cold-blooded animals for their survival. To survive in cold weather, frogs enter into a hibernation state which is more than just a winter nap. Also, the food sources get reduced in winter.įrogs can survive in cold weather by adapting a few survival strategies. So, it becomes difficult to regulate their body temperature in cold weather. Since frogs are ectothermic animals, these amphibians depend on the temperature of nature. ![]() Many of these programs offer a free version with limited features or a trial version that can recover a limited amount of data before you need to purchase the full version.

Place the panel against this section of the stud wall, raise it up until it is flush against the ceiling and use an offcut of plasterboard (around 15mm in width) at the base of the panel to wedge it in place until the adhesive has set. Alternative repair for when lime plastering has started to come away from the laths behind. ![]() Keep a gap of around 100mm between each line of adhesive. For brick/concrete wall: to glue plasterboard to brick wall, apply the adhesive to the rear of the panel, in wavy vertical lines that start and finish around 30mm from the top and bottom, as well as the sides.Place the panel against this section of the stud wall, raise it up until it is flush against the ceiling and use an offcut of plasterboard (around 15mm in width) at the base of the panel to wedge it in place until the adhesive has set. For stud wall: squeezing the caulk gun trigger carefully but firmly, apply a bead of adhesive along the centre of the horizontal and vertical studs that the panel of plasterboard will cover. ![]() Cut the tip off the adhesive cylinder’s nozzle at a 45-degree angle to create an aperture of around 10mm. When cutting, make sure every panel is around 15mm short of wall height, in order to give your plasterboard enough clearance to allow for floor expansion behind the skirting boards. Use as many whole sheets as possible to minimise cutting and waste of plasterboard. The Plaster Magic Homeowners Pack, adhesive repair system was designed specifically to reattach plaster to wood lath and masonry substrates (like brick. Measure the walls you are looking to cover and mark out where you will need to cut your plasterboard to fit. How to achieve the best fixing for plasterboard ![]() Leave it to Venus Williams to hit a grand slam in the mineral sunscreen world. Just to make things trickier, keep in mind that the FDA doesn’t regulate the terms “reef-safe” or “reef-friendly.” That means you need to check labels for two things - no oxybenzone, octocrylene, or octinoxate, and no nano-particles. If your goal is an eco-friendly option, a mineral sunscreen in a cream or lotion form is typically a better option than a mist or spray, and it’s certainly a better option than a chemical sunscreen. But it’s not because of their ingredients - it actually has to do with particle size.Ĭoral reefs can absorb nano-particles, or excessively small particle sizes, from sunscreens - no matter what ingredients they contain. This doesn’t mean mineral sunscreens are automatically a better environmental choice. Some of the ingredients in chemical sunscreens - looking at you, oxybenzone, octocrylene, and octinoxate - have been linked to the dying coral reefs. There’s also a serious environmental consideration at play. Troublesome ingredients aren’t the only debate in the physical versus chemical sunscreen decision. “For that reason, many of my patients prefer chemical sunscreens, because they’re easier to apply and wear,” Hale says. Mineral sunscreens also tend to be less water-resistant than chemical formulas, which means you may need to apply them more frequently, especially after swimming or sweating. This was particularly noticeable on darker complexions. Criticisms of mineral sunscreensĮarly versions of mineral sunscreens - and even some formulations floating around today - were chalky and hard to spread, and they left a noticeable white cast on skin. Sounds great, right? Unfortunately, there are downsides to mineral sunscreens. She also says they offer broad-spectrum protection against UVA and UVB rays, and they work to prevent UVA-related skin damage, like wrinkles and hyperpigmentation. “Zinc oxide sunscreens are often recommended for people with skin sensitivities (including acne), and they’re gentle enough to use on children,” Hale explains. Common mineralsĪs it happens, zinc oxide and titanium dioxide are the main ingredients in most mineral sunscreens. Until we know more, just two active ingredients currently used in sunscreens are generally recognized as safe and effective: zinc oxide and titanium dioxide. That’s a red flag, because the FDA doesn’t have enough information about if these lingering chemicals are causing harm. They are detectable on both the skin and in the blood up to 3 weeks after application. Nothing is finalized, even now, but the FDA reported on a clinical study that showed these six active ingredients entered the bloodstream after a single application and stayed there for a lengthy amount of time. Food and Drug Administration (FDA) proposed new rules and regulations that would update sunscreen requirements to ensure their safety and efficacy. ![]() If you’re side-eyeing some of those ingredients, you aren’t alone. “There are six types of chemical UV filters commonly used in sunscreens: oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate,” Hale says. If we’re being completely honest, the latter is typically recognized for its nicer texture. ![]()
