How To Find Bed Bugs - How To Know If You Have Bed Bugs
Bed Bugs Appearance and Life Cycle
Knowing what to look for is the first step in identifying and controlling bed bugs. There are many bugs that look like bed bugs, so an accurate identification is a critical first step to avoid costly treatment for the wrong bug. The types of bugs that look like bed bugs will vary somewhat depending on your region of the country, but photos and descriptions of common look-alikes have been compiled by researchers:
Adult bed bugs, in general, are:
about the size of an apple seed (5-7 mm or 3/16 - 1/4 inch long);
long and brown, with a flat, oval-shaped body (if not fed recently);
balloon-like, reddish-brown, and more elongated (if fed recently);
a “true bug” (characteristics of true bugs include a beak with three segments; antenna that have four parts; wings that are not used for flying; and short, golden-colored hairs); and
smelly, with a “musty-sweetish” odor produced through glands on the lower side of the body.
Young bed bugs (also called nymphs), in general, are:
smaller, translucent or whitish-yellow in color; and
if not recently fed, can be nearly invisible to the naked eye because of coloring and size.
Bed bug eggs, in general, are:
tiny, the size of a pinhead;
pearl-white in color; and
marked by an eye spot if more than five days old.

How a bee stinger works
How a bee stinger works
A bee sting is the wound and pain caused by the stinger of a female bee puncturing skin. Bee stings differ from insect bites, with the venom of stinging insects having considerable chemical variation. The reaction of a person to a bee sting may vary according to the bee species. While bee stinger venom is slightly acidic and causes only mild pain in most people, allergic reactions may occur in people with allergies to venom components.
Stinging insects use stingers for two main purposes: defense and predation. Honey bees and bumble bees use their stingers strictly for defense. Bees that are away from the hive foraging will rarely sting unless they are stepped on or unnecessarily aggravated. They are usually too busy searching for pollen and nectar to be bothered by a curious observer or passerby

One dead, 30 injured from severe turbulence on aircraft
One dead, 30 others injured due to severe turbulence on board a Boeing aircraft from London to Singapore
What Is Turbulence?
In so many words, it’s the drink spiller, the luggage shaker, the nerve jerker. Turbulence occurs when an airplane hits a strong wind current that can push or pull the plane. Most commercial jets fly high enough to avoid these wind patterns, but gusts can happen at any altitude. There are different types of turbulence an aircraft may experience.
What Causes Airplane Turbulence?
Many environmental factors contribute to airplane turbulence, but the number one factor that causes turbulence is a change in the atmosphere. The following are also common causes of turbulence in an aircraft:
https://www.sheffield.com/airplane-turbulence
One person has died and 30 more people are injured as a Boeing 777-300ER flying from London to Singapore plunged some 7,000 feet in six minutes while encountering severe turbulence.
turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers.
Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This increases the energy needed to pump fluid through a pipe.
The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping in a fluid flow. However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence create a very complex phenomenon. Richard Feynman described turbulence as the most important unsolved problem in classical physics

Coal Blasting Gone Wrong
Coal Blasting Gone Wrong
Blasting
Blasting is an integral part of surface mining operations. To uncover coal reserves, the rocks overlying the coal are broken with explosives and excavated with various types of large earth-moving equipment. Without blasting, a vital part of the nation's energy reserve would be inaccessible
The Surface Mining Control and Reclamation Act of 1977 (SMCRA) requires that coal mining be conducted in a manner that prevents injury to people and damage to public or private property during blasting. The side effects of blasting include:
Flyrock - a rock or rocks moving through the air or along the ground after a blast and travel beyond the blast area (security zone).
Ground vibrations - a seismic wave that moves through the ground following a blast.
Airblast - a concussion (or pressure) wave that moves through air following a blast.
Fumes - the gaseous byproducts that are the result of an explosives detonation.
Dust - small particles of earthen material that may be temporarily suspended in air.
The most dangerous and apparent of these is flyrock. Injury or death to people and property damage may happen when a piece of rock is thrown beyond the permit boundary. The blaster is responsible for preventing flyrock and controlling ground vibration, airblast and fumes. OSMRE oversees the only national program to certify blasters. Training provided for blaster certification addresses the control of flyrock, vibrations, airblast and fumes by the appropriate use of explosives and hazard recognition in the field.
Ground vibrations and airblast may cause people's homes to shake. When people feel their homes shake, they may associate damage to their homes as being a direct result of blasting at a surface coal mine.
https://www.osmre.gov/programs/regulating-active-coal-mines/blasting
Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests

Woman crashes into lamppost, flips car during driving test
A driving test (also known as a driving exam or driver's test in some places) is a procedure designed to test a person's ability to drive a motor vehicle. It exists in various forms worldwide, and is often a requirement to obtain a license to drive a vehicle independently. A driving test generally consists of one or two parts: the practical test (sometimes called a road test in the United States), used to assess a person's driving ability under normal operating conditions,[1] and a theory test (written, oral or computerized) to confirm a person's knowledge of driving and relevant rules and laws.

International Criminal Court - ICC - seeks arrest warrants including PM Netanyahu, for war crimes
International Criminal Court seeks arrest warrants for Hamas and Israeli leaders, including PM Netanyahu, for war crimes
The prosecutor of the International Criminal Court has requested arrest warrants for Israel's Prime Minister Netanyahu and Defense Minister Gallant
In addition, the ICC prosecutor seeks arrest warrants against the Hamas leaders Yahya Sinwar, Mohammed Al-Masri, and Ismail Haniyeh
The International Criminal Court (ICC or ICCt)[2] is an intergovernmental organization and international tribunal seated in The Hague, Netherlands. It is the first and only permanent international court with jurisdiction to prosecute individuals for the international crimes of genocide, crimes against humanity, war crimes and the crime of aggression. The ICC is distinct from the International Court of Justice, an organ of the United Nations that hears disputes between states
Established in 2002 pursuant to the multilateral Rome Statute, the ICC is considered by its proponents to be a major step toward justice, and an innovation in international law and human rights. However, it has faced a number of criticisms from governments and civil society groups, including objections to its jurisdiction, accusations of bias, Eurocentrism and racism, questioning of the fairness of its case selection and trial procedures, and doubts about its effectiveness
The International Criminal Court (ICC) investigates and, where warranted, tries individuals charged with the gravest crimes of concern to the international community: genocide, war crimes, crimes against humanity and the crime of aggression. As a court of last resort, it seeks to complement, not replace, national Courts. Governed by an international treaty called the Rome Statute

1932 USA, Steam Train Crash, Roosevelt Hoover Train Collision, Iowa State Fair
1932 USA, Steam Train Crash, Roosevelt Hoover Train Collision, Iowa State Fair
The great train crash that saved the Iowa State Fair
Connolly’s idea? Lay a section of railroad track in front of the grandstand and create a head-on collision of two locomotives, causing an earth-shaking fireball explosion the likes of which no one had ever seen. No kidding.
The Fair got on board. Connolly bought a couple of old trains that were headed for the scrap heap, laid down some tracks, and set the trains on a crash course.
The prospect of witnessing of a huge train wreck was too much for anyone to pass up. The first explosion in 1896 was so successful that they did it again in 1922 and 1932. Each time, the Fair drew between 40,000 and 70,000 paying visitors—huge crowds for any event in that era.

Video - Scottie Scheffler arrested after he tried to drive past a police officer
World No. 1 golfer Scottie Scheffler was detained in handcuffs after he tried to drive past a police officer at the PGA Championship, ESPN reports
Scottie Scheffler arrested outside PGA Championship and charged with assault on police officer
World No. 1 golfer and Masters champion Scottie Scheffler is facing four charges following his arrest outside the PGA Championship in Louisville, Kentucky, Friday morning.
Scheffler was charged with second-degree assault on a police officer – a felony – along with lesser charges of third-degree criminal mischief, reckless driving and disregarding signals from officers directing traffic, Jefferson County court records show. He’s been released from jail, according to the Louisville Metro Department of Corrections.
https://amp.cnn.com/cnn/2024/05/17/sport/scottie-scheffler-detained
Scott Scheffler (born June 21, 1996) is an American professional golfer who plays on the PGA Tour. He is currently ranked world number one, first reaching the position in the Official World Golf Ranking in March 2022, and has held that ranking for over 80 weeks. He has won two major championships, both the 2022 and 2024 Masters Tournament.[4] He became the first player to win The Players Championship in back-to-back years in 2023 and 2024
Scheffler earned his 2019 Web.com Tour card through qualifying school.
On May 26, 2019, Scheffler fired a bogey-free, 9-under 63 — playing the back nine in 30 — to force a playoff with 54-hole leader Marcelo Rozo in the Evans Scholars Invitational. He then birdied the second extra hole for his first Web.com Tour victory.
On August 18, 2019, Scheffler won the Nationwide Children's Hospital Championship in Columbus, Ohio. Scheffler shot 4-under 67 in the final round at Ohio State University's Scarlet Course for a two-shot victory. He totaled a 12-under 272 for the week and finished two shots ahead of Brendon Todd, Beau Hossler and Ben Taylor. This event was part of the Korn Ferry Tour Finals (the Web.com Tour was renamed the Korn Ferry Tour in mid-season). Scheffler led both the Finals points list and the overall points list to earn a fully exempt PGA Tour card for the 2020 season. He was later named Korn Ferry Tour Player of the Year.

A microscopic tardigrade going for a stroll through some algae.
Tardigrades (/ˈtɑːrdɪɡreɪdz/) known colloquially as water bears or moss piglets, are a phylum of eight-legged segmented micro-animals.[2][6] They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who called them Kleiner Wasserbär ('little water bear').In 1777, the Italian biologist Lazzaro Spallanzani named them Tardigrada (/tɑːrˈdɪɡrədə/), which means "slow steppers"
Tardigrades are near-microscopic animals that can survive some of the most extreme conditions on Earth, including freezing temperatures, crushing pressures, and even the vacuum of space
Tardigrades, often called water bears or moss piglets, are near-microscopic aquatic animals with plump, segmented bodies and flattened heads. They have eight legs, each tipped with four to eight claws or digits, and somewhat resemble the hookah-smoking caterpillar from "Alice in Wonderland." Though tardigrades are disarmingly cute, they are also nearly indestructible and can even survive in outer space
https://www.livescience.com/57985-tardigrade-facts.html
The largest adults may reach a body length of 1.5 mm (0.059 in), the smallest below 0.1 mm (0.0039 in). Newly hatched tardigrades may be smaller than 0.05 mm (0.0020 in). For comparison, grass pollen is typically 0.025–0.04 mm (0.00098–0.00157 in).

Co-pilot of the plane that dropped the atomic bomb on Hiroshima meets a Japanese survivor
Co-pilot of the plane that dropped the atomic bomb on Hiroshima meets a Japanese survivor on a late night show called ‘This Is Your Life’, 1955
Hiroshima, a modern city on Japan’s Honshu Island, was largely destroyed by an atomic bomb during World War II. Today, Hiroshima Peace Memorial Park commemorates the 1945 event.
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days after the bombing of Nagasaki and the Soviet Union's declaration of war against Japan and invasion of Japanese-occupied Manchuria. The Japanese government signed the instrument of surrender on 2 September, effectively ending the war
In the early morning hours of August 6, 1945, a B-29 bomber named Enola Gay took off from the island of Tinian and headed north by northwest toward Japan. The bomber's primary target was the city of Hiroshima, located on the deltas of southwestern Honshu Island facing the Inland Sea. Hiroshima had a civilian population of almost 300,000 and was an important military center, containing about 43,000 soldiers

Real life size comparison between a female and male Kodiak bear
The size comparison between a female and male Kodiak bear
The Kodiak bear (Ursus arctos middendorffi), also known as the Kodiak brown bear, sometimes the Alaskan brown bear, inhabits the islands of the Kodiak Archipelago in southwest Alaska. It is one of the largest recognized subspecies or population of the brown bear, and one of the two largest bears alive today, the other being the polar bear. They are also considered by some to be a population of grizzly bears
Physiologically and physically, the Kodiak bear is very similar to the other brown bear subspecies, such as the mainland grizzly bear (Ursus arctos horribilis) and the extinct California grizzly bear (U. a. californicus), with the main difference being size, as Kodiak bears are on average 1.5 to 2 times larger than their cousins. Despite this large variation in size, the diet and lifestyle of the Kodiak bear do not differ greatly from those of other brown bears.
Kodiak bears have interacted with humans for centuries, especially hunters and other people in the rural coastal regions of the archipelago. The bears are hunted for sport and are encountered by hunters pursuing other species. Less frequently, Kodiak bears are killed by people whose property (such as livestock) or person are threatened.

Most trapdoor spiders are misleadingly named, as not all species make a door for their burrows.
Most trapdoor spiders, but not all, are misleadingly named, as not all species make a door for their burrows. For those species that do, these highly camouflaged entrances are almost undetectable, unless the door is open.
The common name covers several families of spiders, including the Idiopidae, Actinopodidae, Ctenizidae, Migidae and Cyrtaucheniidae. The Brown Trapdoor (Arbanitis sp) and the Spotted Trapdoor (Aganippe sp) spiders belong to the family Idiopidae. They include a wide variety of types, many of which are adapted to drier habitats.

Six-Eyed Sand Spider Burying Itself
Six-Eyed Sand Spider Burying Itself
Hexophthalma hahni (synonyms Sicarius hahni and Sicarius testaceus), known along with other members of the genus as the six-eyed sand spider, is a member of the family Sicariidae, found in deserts and other sandy places in southern Africa. Due to their flattened stance and laterigrade legs, they are also sometimes known as six-eyed crab spiders. Its specific name honours Carl Wilhelm Hahn
the six eyed sand spider is one of the deadliest spiders in the world it can cause severe bleeding or even death.
The perfection of a sand spider’s ability to hide itself so completely is one of the most remarkable, and ingenious, examples of nature at work that we’ve heard of—offering the lowly sand spider both protection from predators and the ability to sneak up on her own prey almost completely undetected. Of course, she’s helped out quite a bit not just by her superior hiding skills, but also by the way her natural coloring blends so flawlessly with the color of the sand she’s hiding in. Don’t be fooled by this tiny, six eyed spider’s diminutive size, however! Although sand spiders are very shy (as is clearly demonstrated in this video), we’re told that they’re not only venomous, but among the most venomous of all spiders.
Fortunately for both us and the spider, however, sand spiders rarely come into contact with humans—and, when they do, they almost never bite. Which makes a video like this, with such up close and personal footage of a sand spider in action, as rare as it is fascinating. Some people are intrigued by spiders, but even if you’re not one of them, we think you’ll enjoy checking this video out. It’s not often that one finds such great footage of a creature so rarely seen by the human eye. So you should definitely hit the Play button now, and maybe even consider forwarding this along to anyone you know who’s interested in spiders—or in disguises and camouflage, or anyone who just enjoys watching the miracles of nature in action!
WHAT DO SPIDERS LOOK LIKE?
The world’s 40,000-plus spider species come in all shapes, sizes, and colors. But here are a few common characteristics to help you distinguish spiders from other insects:
All spiders have eight legs and six to eight eyes.
A Spider has two body regions: the cephalothorax and the abdomen.
Male spiders are normally smaller and have different color markings than females.

How A Gun Silencer Works
How A Gun Silencer Actually Works
A gun silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that suppresses the blast created when a gun (firearm or airgun) is discharged, thereby reducing the acoustic intensity of the muzzle report (sound of a gunshot) and jump, by modulating the speed and pressure of the propellant gas released from the muzzle. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle, or an integral part of the barrel.
A typical gun silencer is a metallic (usually stainless steel or titanium) cylinder containing numerous internal sound baffles, with a hollow bore to allow the bullet to exit normally. During firing, the bullet passes through the bore with little hindrance, but most of the expanding gas ejecta behind it is redirected through a longer and convoluted escape path created by the baffles, prolonging the release time. This slows down the gas and dissipates its kinetic energy into a larger surface area, reducing the blast intensity, thus lowering the loudness.

Substation Disconnect - Huge Electric Arc
Substation Disconnect Mammoth Electrical Arc
An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or by field emission.[1] After initiation, the arc relies on thermionic emission of electrons from the electrodes supporting the arc. An arc discharge is characterized by a lower voltage than a glow discharge. An archaic term is voltaic arc, as used in the phrase "voltaic arc lamp".

How to Change a Flat Tire - Change a flat car tire step by step
How to Change a Tire - Change a flat car tire step by step
A flat tire (British English: flat tyre) is a deflated pneumatic tire, which can cause the rim of the wheel to ride on the tire tread or the ground potentially resulting in loss of control of the vehicle or irreparable damage to the tire. The most common cause of a flat tire is puncturing of the tire by a sharp object, such as a nail or pin, letting the air escape. Depending on the size of the puncture, the tire may deflate slowly or rapidly.

Electrical Safety: Slow Motion 480 Volt Arc Flash
Electrical Safety: Slow Motion 480 Volt Arc Flash
An arc flash is the light and heat produced as part of an arc fault, a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system.
An arc flash is the light and heat produced from an electric arc supplied with sufficient electrical energy to cause substantial damage, harm, fire, or injury. Electrical arcs experience negative incremental resistance, which causes the electrical resistance to decrease as the arc temperature increases. Therefore, as the arc develops and gets hotter the resistance drops, drawing more and more current (runaway) until some part of the system melts, trips, or evaporates, providing enough distance to break the circuit and extinguish the arc. Electrical arcs, when well controlled and fed by limited energy, produce very bright light, and are used in arc lamps (enclosed, or with open electrodes), for welding, plasma cutting, and other industrial applications. Welding arcs can easily turn steel into a liquid with an average of only 24 DC volts. When an uncontrolled arc forms at high voltages, and especially where large supply-wires or high-current conductors are used, arc flashes can produce deafening noises, supersonic concussive-forces, super-heated shrapnel, temperatures far greater than the Sun's surface, and intense, high-energy radiation capable of vaporizing nearby materials.
Arc flash temperatures can reach or exceed 35,000 °F (19,400 °C) at the arc terminals.
