You'll find seahorses in the world's tropical and temperate coastal waters, swimming upright among seaweed and other plants. Seahorses use their dorsal fins (back fins) to propel slowly forward. To move up and down, seahorses adjust the volume of air in their swim bladders, which is an air pocket inside their bodies.

Tiny, spiny plates cover seahorses' bodies all the way down to their curled, flexible tails. The tail can grasp objects, helpful when seahorses want to anchor themselves to vegetation.

A female seahorse lays dozens, sometimes hundreds, of eggs in a pouch on the male seahorse's abdomen. After seahorse moms make their eggs, they pass them over to the males to carry until the young are released. When it's time to give birth, the dad pumps water through the pouch, releasing hundreds of fry, or baby seahorses, in just a few minutes. Called a brood pouch, it resembles a kangaroo's pouch for carrying young. Seahorses young hatch after up to 45 days in the brood pouch. The baby seahorses, each about the size of a jelly bean, find other baby seahorses and float together in small groups, clinging to each other using their tails. Unlike kangaroos, baby seahorses do not return to the pouch. They must find food and hide from predators as soon as they're born.

Take this fun quiz to see how much you know about seahorses.

Tiger sharks are named for the dark, vertical stripes found mainly on juveniles. As these sharks mature, the lines begin to fade and almost disappear.

Shark Attacks

These large, blunt-nosed predators have a duly earned reputation as man-eaters. They are second only to great whites in attacking people. But because they have a near completely undiscerning palate, they are not likely to swim away after biting a human, as great whites frequently do.

Hunting

They are consummate scavengers, with excellent senses of sight and smell and a nearly limitless menu of diet items. They have sharp, highly serrated teeth and powerful jaws that allow them to crack the shells of sea turtles and clams. The stomach contents of captured tiger sharks have included stingrays, sea snakes, seals, birds, squids, and even license plates and old tires.

Population

Tiger sharks are common in tropical and sub-tropical waters throughout the world. Large specimens can grow to as much as 20 to 25 feet in length and weigh more than 1,900 pounds.

Threats to Survival

They are heavily harvested for their fins, skin, and flesh, and their livers contain high levels of vitamin A, which is processed into vitamin oil. They have extremely low repopulation rates, and therefore may be highly susceptible to fishing pressure. They are listed as near threatened throughout their range.

DIY robot turns plastic bottles into filament

# data[].attributes.attachment_link.readable_text
A new robot called PetBot automates the plastic recycling process by cutting PET bottles into tape before turning it into filament, a report by Hackaday explains.

The robot, built by JRT3D, carries out the two separate processes at the same time using the same stepper motor.

In a video (below) that reminds us of a Rube Golberg or Wallace and Gromit machine, you can see PetBot cutting the bottles at the same time as turning it into filament further along in the process.

To start off, the user cuts a bottle in half and pushes the open rim between two bearings where a cutter slices the plastic into tape.

The tape is moved by a driven spool to the second part of the machine, which drives the plastic through an extruder where it's heated up just enough so it can be pulled through without breaking.

While the machine looks great in action, it does have its limitation. One example is that the machine doesn't fully automate the cutting process, meaning that someone has to be at hand to cut the bottles and place a new one when the previous bottle has run out.

Joining a long list of DIY recycling projects

Still, while some might be disappointed that PetBot isn't, in fact, a dog-like pet robot, this is a pretty impressive project that could help in the much-needed race for new innovations in plastic recycling.

As 10 million tonnes of plastic waste end up in the ocean every year, according to the World Economic Forum, a machine similar to PetBot would undeniably make a worthwhile DIY project.

JRT3D's PetBot joins a long list of other similar machines, such as DIY powerwalls made out of recycled laptop batteries and a homemade shower loop for reduced water waste.

JRT3D is selling the machine for $400 on the website of Precious Plastic an organization that enables people to start plastic recycling businesses with homemade inventions, and the inventor also says in his YouTube videos that a Kickstarter campaign is coming soon.

Ancient Lava Reveals Earth's Magnetic Field

Ancient Lava Reveals Earth's Magnetic Field

# data[].attributes.attachment_link.readable_text
We know that Earth's magnetic field is always shifting in its direction and its strength. Just how quickly these changes are happening is of great interest, considering this planetary feature keeps us all protected from violent cosmic radiation.

Now, a new analysis of ancient lava flows in eastern Scotland - filling in some crucial blanks in our magnetic field history - has backed up previous research pointing to a 200-million-year cycle during which the field weakens and then strengthens again.

The team also used the magnetic history they found buried in the geological record to double-check other measurements made over the last few decades, and to chart a history of Earth's magnetic field going back some 500 million years.

"Our findings, when considered alongside the existing datasets, support the existence of an approximately 200-million-year long cycle in the strength of the Earth's magnetic field related to deep Earth processes," says paleomagnetist Louise Hawkins, from the University of Liverpool in the UK.

"As almost all of our evidence for processes within the Earth's interior is being constantly destroyed by plate tectonics, the preservation of this signal for deep inside the Earth is exceedingly valuable as one of the few constraints we have."

Thermal and microwave paleomagnetic analysis techniques were used on rock samples from the ancient lava flows, with the alignment of mineral crystals inside them revealing the state of Earth's magnetic field at the time they were originally formed.

The team discovered that between 332 and 416 million years ago, there was a dip in the magnetic field that matches up with another one from 120 million years ago. During the earlier period, now called the Mid-Palaeozoic Dipole low (MPDL), the field surrounding Earth was around a quarter of the strength that it is today.

Those dates match up with the 200-million-year cycle, and give experts some important new insights into how the magnetic field was behaving more than 300 million years ago, in the lead up to a notable Superchron - the name given to an extended period of time when the field stays stable.

"This comprehensive magnetic analysis of the Strathmore and Kinghorn lava flows was key for filling in the period leading up the Kiman Superchron, a period where the geomagnetic poles are stable and do not flip for about 50 million years," says Hawkins.

If this cycle holds true, and the magnetic pole flips or reversals tend to happen every 200,000-300,000 years, we're actually due for another one - much to the concern of scientists, who aren't sure what the effect will be on all the technology and gadgets we obviously didn't have last time it happened.

The more we know about the history of Earth's magnetic field in general, the better we can predict what it's going to do next. If our force field against space radiation starts to develop problems, we need to know about it as early as possible.

There was another bonus finding to the research too: it has previously been thought that flips in the magnetic field's orientation happen when the field is weaker, and this is another hypothesis that the new data backs up.

"Our findings also provide further support that a weak magnetic field is associated with pole reversals, while the field is generally strong during a Superchron, which is important as it has proved nearly impossible to improve the reversal record prior to around 300 million years ago," says Hawkins.

The research has been published in .

Officials are urging members of the public to come forward with information after two sea turtle nests on a Florida beach were vandalized over the Fourth of July weekend.

Members of the Escambia County Sea Turtle Patrol, a group that is part of the county's conservation program, found one loggerhead nest enclosure on Pensacola Beach was destroyed, and another appeared to have been dug at, according to an Escambia County press release. The county, which shared photos of the disturbed nests on its Facebook page, said the eggs appeared to be unharmed.

Pensacola Beach currently has eight loggerhead nests, while another is on Perdido Key around 27 miles away. Loggerheads, which are deemed a threatened species in Florida, are among the five types of sea turtle that inhabit the state's waters and use its beaches to nest. The others are the green, leatherback, Kemp's ridley and hawksbill, which are all endangered.

Log into Facebook to start sharing and connecting with your friends, family, and people you know.

To protect these animals, enclosures are put up to keep beachgoers away. Only designated volunteers are allowed to check on them and ensure they have not been disturbed.

Sea turtles are protected under both federal and state law, and individuals who harass or disturb adults, their hatchlings, eggs, or nests can be hit with fines or prison time.

Escambia County alerted the Florida Fish and Wildlife Commission (FWC) and Escambia County Sheriff's Office about the incident, but said enforcing laws can be tough when little information is available.

It asked anyone with information about the vandalism to call the FWC's Wildlife Alert Hotline at 1-888-404-3922.

The incident comes ahead of the Pensacola Beach Air Show, held between July 7 and 10, featuring the U.S. Navy's Blue Angels flight demonstration squadron. The event can attract huge crowds.

Marine resources division manager captain Robert Turpin said in a statement: "With the upcoming Pensacola Beach Blue Angels Air Show, Escambia County Marine Resources Division urges boaters and beachgoers to watch out for sea turtles, shorebirds and other coastal wildlife.

"Beachgoers should respect sea turtle and shorebird nests and stay out of posted areas. Boaters should keep a sharp lookout for turtles and manatees resting on the surface and be aware of shallow seagrass areas.

"Both boaters and beachgoers can help protect coastal wildlife by properly stowing trash and remembering to 'Leave No Trace' at the end of their day."

The Leave No Trace initiative asks beachgoers to keep the beach as they found it, and turn off lights that can confuse hatchlings during the spring and summer months. This prevents the reptiles from being disturbed during their nesting season, which runs between May and October 31. During this period, thousands of endangered turtles lay eggs on beaches on the shore of the Atlantic and Gulf Coast.

In its news release announcing the vandalism of the nests, Escambia County said those who find sea turtles on the beach should keep away, turn of any lights, and not to touch the animals.

If any wildlife appears to be injured or in danger, the Escambia County Marine Resources can be reached at (850) 554-5869 or (850) 426-1257, or FWC's Wildlife Alert Hotline at 1-888-404-3922.

If you're in Tampa Bay, Florida, and you want to spend the day at the beach, you might want to wait for a few months. Right now, the beaches in the area are covered in dead, rotting fish.

"The bay is really hurting right now," Maya Burke, who lives in Pinellas County, told . "It's significant numbers of dead fish all up and down the food chain, from small forage fish all the way up to tarpon, manatees, dolphins. ... If it's swimming in the bay, right now it's washing up dead."

According to reports, the fish were killed by a severe Florida red tide. The bloom of toxic algae arrives every year in Florida's Gulf coast, but this year, it's different. The algae that causes red tides are called Karenia brevis, and they call the Gulf of Mexico home. Generally, however, the Tampa Bay area doesn't see blooms of this severity in the summer. In fact, the worst of them usually begin occurring around autumn and are gone by January - but the summer blooms have been happening with more frequency in recent years.

Since the 1990s, there have only been four summertime blooms in the area. One in 1995, another a decade later in 2005 and, most recently, in 2018. "This is not normal," Richard Stumpf, an oceanographer at the National Oceanic and Atmospheric Administration, explained to NPR. "The fact that it's been three years since the last one is not good."

This #RedTide is something serious 🤮 pic.twitter.com/73G5Kt1WZV

- Evan Ligon (@legacysportsmed) July 12, 2021

The first of the dead fish showed up in early June, dying at the site of the algae blooms, gathering in huge, floating groups before washing to shore en masse. As of this reporting, the reason for the red tide's severity hasn't been pinpointed, but researchers are theorizing that a catastrophic, 215 million-gallon wastewater spill in April where toxic water was dumped into the estuary from the an old fertilizer plant at Piney Point could be playing a part. Experts also suspect that Tropical Storm Elsa, the earliest fifth-named storm on record in the Atlantic that hit in early July, has something to do with the massive amount of dead fish piling up in the bay.

So far, Floridian officials have cleaned up an astounding 600 tons of dead fish, much of it from the St. Petersburg area. And there's no end in sight. "We scrape the beaches," said St. Petersburg's emergency manager Amber Boulding during a news conference. "We get it cleaned up, but as soon as those tides change, we have fish right back in. We don't know the end of it."

The last summertime red tide in the area was in 2018, and it was so bad it killed manatees and dolphins. In humans, a red tide can cause respiratory irritations, and it's of course a deterrent to tourists looking to enjoy the beaches.

Construction technology continues to evolve, including the creation of a variety of infrastructure, including three-dimensional (3D) prints. 3D printing allows you to create free-form structures in a single piece, which reduces the consumption of materials.

Now, the world's first 3D-printed steel structure, a 'living laboratory' bridge, has been unveiled by a robot in Amsterdam. This pedestrian bridge with smart sensors will replace the old bridge under external restoration for the next two years.

The 3D-printed footbridge, which is over four years in the making, is the result of a unique collaboration between MX3D, software company Autodesk, chief engineer Arup, steel giant ArcelorMittal, the City of Amsterdam, and the University of Twente, among others.

MX3D made this design possible by turning welding robots with intelligent software into industrial 3D printers. The entire bridge is made of stainless steel and weighs 6,000 kg. The footbridge will be extensively tested by Imperial College London, with the help of the University of Twente, before being installed.

Using its vast network of installed sensors, researchers will measure, monitor, and analyze the performance of the novel 12-meter-long structure as it handles pedestrian traffic. The data collected will enable researchers and engineers to measure the bridge's 'health' in real-time, monitor how it changes over its lifespan, and understand how the public interacts with 3D-printed infrastructure.

The data from the sensors will be put into a 'digital twin' of the bridge - a computerized version that will imitate the physical bridge with growing accuracy in real-time as sensor data come in. The performance and behavior of the physical bridge will be tested against the twin, which will help answer questions about the long-term behavior of 3D-printed steel, as well as its use in real-world settings and in future novel construction projects.

The data captured from the 3D-printed footbridge will be made available to other researchers worldwide who want to work with the Turing researchers in analyzing the data. Now the bridge is unveiled, the researchers will begin collecting data in real-time to monitor how it behaves.

Taxon: Freshwater fish

Range: Native to the Western United States; introduced throughout North America

Status: Not listed under the Endangered Species Act

Rainbow trout are coldwater fish that have long been associated with clear, healthy mountain streams and lakes in North America. Because of their ability to thrive in hatcheries, rainbow trout have been introduced into much of the United States and now inhabit many streams and lakes throughout the country. The popularity of rainbow trout among anglers has placed it among the top five sport fishes in North America, and it is considered by many to be the most important game fish west of the Rocky Mountains.

However, reduction of good quality trout habitat due to streambank and upland soil erosion, loss of riverside vegetation, water diversion, logging and mining activities, and pollution from municipal development and agriculture have significantly reduced the distribution and abundance of rainbow trout. In addition, construction of dams, road crossings, and other structures impede the ability of rainbow trout to migrate upstream and downstream, which is critical to successful completion of their life cycles. Consequently, nine different populations of steelhead (sea-run rainbow trout) have been added to the federal endangered species list.

Appearance

Rainbow trout are a North American game fish that get their name from the beautiful colors that shine on their skin. Coloration of the fish varies widely in relationship to sex, habitat, and maturity. Colors on the back of the fish can range from brown to olive to dark blue. Fish have a pinkish stripe/band running the length of their bodies, with a silvery underside that fades to pearl white. They have small black spots on their backs, fins, and tail. Average mature fish are around 16 inches long and weigh between 2 and 8 pounds. (The largest rainbow ever caught, however, was in Canada and weighed 48 pounds.)

Habitat

Rainbow trout can easily adapt to various aquatic habitats and environments. They prefer cool freshwater streams with gravel bottoms and natural cover, such as downed trees and boulders. These fish prefer water temperatures of 55 to 60 degrees Fahrenheit, but can tolerate temperatures that vary from 32 to 70 degrees Fahrenheit.

Diet

Rainbow trout are opportunistic feeders and will eat anything from aquatic and terrestrial insects, to fish eggs, to small minnows, to crustaceans and worms.

Historical range

The historical range of rainbow trout extends from Alaska to Mexico and includes British Columbia, Washington, Oregon, California, Idaho, and Nevada. Rainbow trout found primarily east of the Cascade Mountains in the U.S. and in the Upper Fraser River of British Columbia are often called redbands. Native rainbow trout are generally found in watersheds west of the Cascades.

Most rainbow trout found outside their historical range are "domesticated" steelhead.

Current range

Rainbow trout distribution. Map by NRCS Wildlife Habitat Management Institute.

Due to popularity as a game fish, they have been introduced into streams and lakes all over North America.

Conservation challenges

Whirling disease has developed in the last several decades and is a threat to trout fisheries across the United States. Primarily affecting hatchery-raised rainbow trout and other salmonids, whirling disease is caused by a microscopic parasite that causes fingerling trout to grow with badly curved spines and other skeletal deformities that can result in high fingerling mortality. Found in 22 states to date, whirling disease made its most significant appearance in wild waters in 1994 in Colorado (upper Colorado River) and Montana (Madison River). Significant efforts are being made to understand whirling disease through research and management of hatchery-raised rainbow trout and wild trout populations with the goal of protecting rainbow trout and other native trout fisheries nationwide.

TALLAHASSEE, Fla. (AP) - The plight of endangered right whales took another sad turn Saturday, when a baby whale, possibly two months old, washed ashore dead on a Florida beach with telltale signs of being struck by a boat.

There are fewer than 400 north Atlantic right whales remaining, and any mortality of the species is a serious setback to rescuing the animals from extinction, according to federal biologists who expressed dismay over Saturday's discovery of the 22-foot (7-meter) male infant at Anastasia State Park near St. Augustine.

"This is a very sad event," said Blair Mase, a whale expert with the National Oceanic and Atmospheric Administration.

"Every mortality that occurs really has a devastating impact on the population as a whole, because they are one of our most critically endangered whales in the world," she said. "Every whale counts."

The infant whale is believed to be the first born of a 19-year-old whale biologists named "Infinity." Both were sighted off Amelia Island in northern Florida on Jan. 17.

The circumstances surrounding the whale's death are under investigation. But federal officials said it was clear that a vessel was involved. The whale suffered propeller wounds to the head and back.

Inclement weather kept biologists from immediately launching a search for the calf's mother to see if she might have also been injured by the collision with a boat.

It was the second calf mortality since the calving season. Another calf was found dead in November on one of North Carolina's barrier islands.

From November to April, right whales swim south from the frigid northern Atlantic to give birth in warmer waters off the northern coast of Florida.

The whales spend those months cruising through waters off the coast, sometimes coming within a couple hundred feet from beaches - which make them vulnerable to boaters and fishing vessels going in and out piers.

Mase said some 40 right whales have been sighted off the southeast coast of the United States, with 15 pairs of moms and their calves.

Federal laws prohibit people from harming the animals. And people are supposed to remain at least 500 yards (460 meters) away from the whales.

"If you're in this area, please give these animals space," said Allison Garrett, a NOAA spokesperson. "The rule is 500 yards - that's five football fields. That includes people, boats, drones, paddle boards - everything. That's the law."

Garrett urged people who come upon one of the rare whales to report the sighting to officials at (877) 942-5343 to help track their numbers.

Ocean vessels and fishing operations - as well as disease - have taken a toll on the whale's numbers.

Since 2017, the animals have been experiencing what biologists call an "unusual mortality event." In those years, at least 33 dead and 13 seriously injured whales have been found - accounting for more than a tenth of the remaining population.

Last month, conservation groups sued the federal government to force it to further accelerate action on proposals meant to protect the whales.

The groups want the government to impose stricter speed limit on ships traveling from Maine to Florida.
