10 Amazing Scientific Discoveries Made Recently

Unless you’re a chemistry major or a science geek, you probably don’t even remember half

the elements of the periodic table taught to you in school. As a refresher, the number

of protons an element has distinguishes it from others, so an atom with eight protons

will always be oxygen. The heaviest element that can commonly be found in nature is element

92, uranium, and elements beyond that are mostly man-made. In 2010, element 117 was

successfully created by a team of researchers, filling the void between elements 116 and

Temporarily being called ununseptium, producing such a heavy element was no easy task. Not

only does it need a lot of energy to create, but finding the right combination of elements

to get a 117-proton element is also a huge problem. Heavier elements also appear to have

shorter half-lives — element 118 only lasted a few milliseconds before decaying. But creating

these heavy elements helps ever-curious scientists find out just how large can an atom go.

Electrons are the negatively-charged particles that orbit a nucleus. They’re so small that

accurately measuring theire mass is no easy task. For years, scientists have been using

the Committee on Data for Science and Technology’s recommended value, which was adopted in 2006.

But recently the mass has been measured at a more precise value of 0.000548579909067

of an atomic mass unit. Or to give you a better idea how small that is, about 9.1 x 10-31

kg. Yes, that’s 30 zeros after the decimal place. Although there’s little difference

between the previously known mass and the new, more precise mass, it has a huge impact

on various fields of science, especially particle physics.

For years, scientists had been experimenting on transforming skin cells into cells of other

organs. So far these experiments have fallen short because the cells produced were immature

versions of the organ cells, but a new study found that it could be possible to produce

mature liver cells from skin cells. The new liver cells were able to thrive on their own

after being transplanted to mice that had been engineered with liver problems.

Scientists were able to make the experiment work by using skin cells at an intermediate

state which have a potential to mature into working liver cells. Although the new liver

cells aren’t 100% matured, tests done on mice with liver problems showed a potential

that this experiment could work on humans in the future. This could help solve the huge

problem of limited donor organ availability.

After decades of wait, we could finally be closer to achieving an unlimited source of

energy without the threat of pollution, greenhouse gases and radioactive waste. This would be

possible with nuclear fusion, a natural process in stars. Fusion happens when atoms fuse into

each other and release energy. When a large quantity of atoms fuse, more energy capable

of sustaining the process is released. This is called ignition, and it’s what’s needed

for a fusion power plant. Scientists believe that it will take many more years before this

could be achieved on a large scale, but recent tiny successes with fusion represent a huge

milestone that could benefit future generations.

Breast cancer is one of the most common types of cancer in the world, affecting hundreds

of thousand people in the United States alone. Recently, a study found a connection between

cholesterol level and breast cancer. The study found that women with higher cholesterol levels

have a higher risk of acquiring breast cancer.

But there may now be a drug that not only lowers your cholesterol, but can also treat

your breast cancer. After an anti-cholesterol drug was injected in mice, proteins that cause

tumors were exterminated. The drug was also effective in reducing the growth of breast

cancer cells and can even kill the cells after it was administered to breast cancer cells

outside the human body. Further tests are needed, but hopefully it’s a step in the

right direction of fighting both high cholesterol and breast cancer.

5. Antibiotic-Resistant Bacteria’s Weakness

The world has been facing the ever-growing problem of antibiotic-resistant bacteria,

which poses an enormous threat to public health because it renders some antibiotics useless.

Antibiotics have been one of the keys that allow us to live longer by fighting bacteria

that cause some of the most common infectious diseases. But some of these bacteria have

adapted to create barriers against antibiotic drugs.

Scientists recently found a possible way to combat these walled bacteria by specifically

attacking the walls instead of the bacteria itself, which just causes the organisms to

find another defense. This gives us the chance to defeat these bacteria and ensure healthier

In the past, living things were divided into two divisions: prokaryotes (single-celled

organisms) and eukaryotes (multi-celled organisms, including us). The prokaryote division was

then further divided into two more domains: bacteria and archaea. And for years we thought

that all life on earth falls into these three categories.

But a fourth domain just might be added after scientists found two viruses in Chile and

Australia bigger than anything found before. Pandoraviruses, named after the Greek figure,

are so alien to us that only 7% of their genes match with all the previously known lineage

in nature. The discovery of these viruses (which are harmless to us) show how little

we still know about microscopic life here on Earth.

Remember when the states of matter were just solid, liquid and gas? Then came plasma, then

Bose-Einstein Condensate, and the list goes on. What could be a new state was recently

discovered, and where else would it be found but in your favorite food, chicken. You might

feel stupid and weird if you look closely into a chicken’s eye, but some researchers

did just that and found the new state of matter known as “disordered hyperuniformity.”

It was named that because the cells found in a chicken’s retina appear to be arranged

randomly, and yet at the same time appear to be somewhat uniform. The materials in this

new state have the efficiency of crystals in the way the density of particles are kept

consistent, and they also have the flexibility of liquid. The new discovery will be a great

help in the development of light-transmitting devices since the cells found in the bird

Our lifelong dream of teleportation that we only see in sci-fi movies looks like it’s

on the verge of becoming… well, not true, but a very distant possibility. Instant teleportation

from the United States to Japan is still impossible, but what scientists achieved was spectacular

enough. Physicists from the Netherlands were able to teleport quantum data regarding an

electron’s spin state to another election located three meters away.

This achievement might be able to prove the existence of “quantum entanglement,” which

Albert Einstein called “spooky action at a distance” and implies that our current

understanding of quantum mechanics is wrong. This truly spooky action allows quantum data

to be transferred from one point to another so fast that it should be even faster than

the speed of light. Quantum teleportation could be the key to quantum computing, which

could give us groundbreaking computing power.

Our planet is already full of water, covering roughly 71% of our surface. But a new ocean,
