The T-Rex and their Sense of Smell

A new study finds that the well known predator the Tyrannosaurus Rex and its species had some of the most amazing sense of smell compared to the rest of the dinosaurs.
Proceedings of the Royal Society B tried to quantify roughly how many genes would have been included in the T- Rex's sniffing skills.
In 2008, researchers found that the t-rex and its siblings gave in large portions of their brains to the sense of smell.
Hughes and his colleague John were interested in the idea of researching a dinosaurs sense of smell and a living reference of them were birds, the last living dinosaurs.

Giant tiger sharks eat backyard birds, surprising study reveals

Tiger sharks have voracious appetites which means that they can eat anything from sea turtles to rubber tires.
new research suggests that baby tiger sharks have an even weirder item on their menu: common backyard birds.
a group of researchers including a researcher named Drymon brought a tiger shark on board and it barfed up feathers.
Other scientists had reported tiger sharks eating birds before, but these were rare.
Drymon and colleagues decided to investigate tiger shark diets as part of their project.

shark fin soup has been banned in 12 states such as California.
but, it can be found there for about 16 dollars.
cutting off the fin on a shark feels like the shark can just keep living without it, but the fin is important to a shark.
without the fin, the shark will die. they will sink to the bottom and, unable to swim and pass water over their gills, suffocate, die of blood loss, or get eaten by other predators.

Eating meat has ‘dire’ consequences for the planet, says report

lots of people diet, but as the human population is rising steadily, scientist are trying to figure out how to invent a dieting plan that can feed 10 billion people.
in a news report, the British medical journal The Lancet, it recommends a largely plant-based diet with small allowances for meat, dairy, and sugar.
Meat and sugar consumption around the world should drop by 50 percent

Elephant orphans face added challenge: bullying

Poaching elephants has caused many problems.
many young elephants have lost their mothers due to poaching, and are relying on their relatives.
this may not seem like a problem, but the young elephants aren't getting the nutrition they need from their mothers.
orphaned elephants take a lot of effort to grow when their biological mother isn't here to love them and take care of them.
they will have a hard time growing and reproducing.

Why Poison Is a Growing Threat to Africa’s Wildlife

the people of Kenya are tired of the lions eating their livestock. one solution is to hunt the lions using poisoned tipped arrows.
they set up a trap for he lions to come. when the lions finally do they get ready to shoot the tranquilizer.
soon the 2 lions that have been eating the livestock come in search of the lioness(the lion that they just tranquilized). the team darted one of the lion, but let the other one escape.
meanwhile other people wanted the lion attacks on their livestock to stop too, but instead they poisoned the animal's carcass and that killed the lions.
by the time the vet came to see the lions, the bodies had already rotted.
therefore if we keep using poison, instead of tranquilizers that just put the animals to sleep, many of the animals would die.

Mars is about to make its closest approach to Earth, and when that happens, its called "blood moon".
both the moon and mars will be seen on July 27 and into the morning of July 28 on July 27 and into the morning of July 28.
On the 27th, mars will reach the opposition.

Meet the World's Most Expensive Pet Fish

The Asian Arowana is the worlds most expensive fish. A woman named Emily Voigt spent all most her whole life searching for that fish. She even wrote a book about it called "the dragon behind the glass" with the picture of the Asian Arowana. This fish was a predator way from the age of the dinosaurs, and looks like a Chinese dragon kite. That spawned a belief that the fish is also good luck and prosperity.
So, because the Asian Arowana is colorful, is from the age of the dinosaurs, looks like a dragon, and belived to have good luck and prosperity, it is the most expensive fish in the world.

South Africa to Export 1,500 Lion Skeletons Per Year—Legally

South Africa is illegally trading lion bones.
Lions are facing a new threat. there is a demand for lion claws, teeth, and bones.
They can be used for medicine, and trinkets, mostly in Southeast Africa.
It is illegal to poach lions, but international trade in lion parts is prohibited.
Because of this, lions are being raised in captivity. some reports say that the lions are being treated badly in terrible conditions.
Therefore, our lion population will soon decrease just because South Africa is killing off lions for illegal trading.

What do animals do in a wildfire?

Some animals escape, while other species survive.
Many wildfires occurred around the world and took many lives and burned through buildings.
Many wildlife animals adapted to the wildfires. Fire is a natural part of a wildlife animal's life.
Many animals can escape the heat. Some birds can fly away, insects and amphibians can dig holes and stay there, other animals can go to lakes and steams.
Some predators can wait for the animals/insects to run out and catch them.
all in all, having a wildfire in a forest isn't so bad, because the animals can survive.

The Mystery of Left-Coiled Snails

Jeremy is a rare left-coiled snail
Dr. Davison discovered him and wanted to know if the cause of the left-coiled shell was due to genetics or was an accident.
Jeremy organs also had turned counterclockwise, which made it hard to mate with right-coiled snails.
Dr. Davison, who hoped to have Jeremy produce offspring, but, after the offspring was produced, it was observed that they all had right-coiled shells.
Jeremy soon died, but his genes were passed on to the University of Nottingham.

High Risk of Baldness for Short People

Short men may have an increased risk of becoming bald prematurely.
An international genetic study at least points in this direction. During the study, the scientists investigated the genetic material of more than 20,000 men. Their data show that premature hair loss is linked to a range of various physical characteristics and illnesses.
Researchers analyzed genetic data from around 11,000 men with premature baldness. Around 12,000 men with no hair loss served as a control. The participants came from seven different countries.

Can Humans Die from Apple Seeds?

Apple seeds are actually poisonous and can kill humans.
First, the amygdalin/poison, is accessible only if the seeds have been crushed or chewed; a whole unbroken seed will pass right through
But you would need a lot of crushed apple seeds.
When in the digestive system, this chemical degrades into highly poisonous hydrogen cyanide (HCN). A lethal dose of HCN can kill within minutes.
The human body can process HCN in small doses, so a couple of chewed seeds are usually completely harmless.
The average adult would need to eat anywhere from 150 to several thousand crushed seeds (depending on the apple variety) to be at risk of cyanide poisoning.
All in all, apple seeds are only dangerous if you eat a whole lot of crushed seeds, which hopefully, will never happen.

The Consequences of Zit Popping

Popping a zit or a pimple may seem like the right thing to do, but it can cause you even more problems.
By popping a zit, it will become an open wound, and potentially infectious bacteria will enter your body.
You can get a scar and picking at or popping any zit makes permanent marks more likely by increasing inflammation.
If you pop a zit and there is no infection or scar, you would still be spreading more zits around.
Therefore you should pop zits because it will end up badly.

Friendly Neighborhood Spider

Spiders might seem dangerous, and you might want to kill them on sight; but, spiders are mostly harmless and help the ecosystem.
Spiders may be providing services like eating pests—some even eat other spiders.
There’s even a species of jumping spider that prefers to eat blood-filled mosquitoes in African homes.
Although they are generalist predators, apt to eat anything they can catch, spiders regularly capture nuisance pests and even disease-carrying insects.
So killing a spider doesn’t just cost the arachnid its life, it may take an important predator out of your home.
All in all, you shouldn't be afraid of harmless spiders.Spiders might actually be useful in your houses, for they can get rid of other annoying, yet more dangerous, insects lurking around.
