The ageing is caused by gradual failing of the complex maintenance system of cells. Doctor Lorna Harries from unveristy of Exter thinks that it is because of the stresses accumulated in the cells and by changing some points we can manipulate the cells live Juan Carlos Izpisúa Belmonte, a professor at the Salk Institute in San Diego is working on a controversial experiment It is conducted on prematurely aging mice. Then they were given an “elixir” that could stop aging and make mice more active and  undo signs of aging. It is actually a technique called epigenetic  reprogramming and it is about stripping away key molecular tags. It is like cleaning all the things in the cells and bringing them back to factory setting. However it can have many complications for example mice developed tumorous and died. It is causing imbalance and can confuse the organism. Doctor Lorna explains that switching the switch is hard and everything has its effects in complex biology. She found genes in mitochondira of human cells However it is not about making  us live longer but help with reverse ageing in specific tissues.

 

Inevitably – something that will happen no matter what

We will all die, it is inevitable 

Rejunavate – make look younger

Hey, I bought a rejunavating face mask for our grandma last week

Maintenance – keeping, making work

We need water to maintain our life functions

Implication -involvment

Switch- change

 Astronomers have calculated that there must be five times as much invisible ‘dark matter’ as ordinary stuff in the cosmos. So, they tried to detect the elusive stuff.

 

 In the article we learn that attempts have been made to find dark matter particles, but with zero success.

As we dig more into the text, we find out that now the dark matter is thought to be placed deep beneath our feet. So far, most attempts to directly detect dark matter have focused on hypothetical particles known as WIMPs.

 

How do we know where to look for it?

 The answer is in the new idea, look for it in ancient rocks. It is thought that WIMPs colliding with the atomic nuclei in certain rock minerals could, create tiny changes to the minerals’ crystal structure.

 

The plan for now is to dig up rocks from 10 kilometres under the surface. Then by using techniques such as helium-ion beam microscopy to look for the tracks. The first results are expected in 2025.

 

We learn about  the research from Dr Katherine Freese and  Sebastian Baum who are taking part in it.

 

If the founding works out, it’ll solve one of the biggest mysteries in science.

Yale School of Medicine researchers have revived the brains of 32 pigs. Brains, it seemed, could be brought back to life. The dead organs were infused with a bood subtitute called BrainEx,which allows cells to recover after oxygen deprivation, and helped maintain the brain's structure and restart partial brain functions. They also found out that electrical activity between brain cells had started up again.

 This is the biggest commotion about brain reanimation since Mary Shelley. According to Prof Nenad Sestan the process of cell death is a gradual, stepwise process, some of those processes can be either postponed, preserved or even reversed. Sestan started off trying to revive animal brain cells as a means to understand brain networks which has raised far-reaching scientific and ethical questions.

How do we define death? Are current guidelines on brain death in need of revision? Should we even be conducting research that raises the smallest possibility of creating consciousness? The Swiss scientist says his team is considering its next set of experiments, but it would be premature to reveal details "even in abstract terms".

Dr Lorna Harries said that cellular ageing is due to accumulated cellular stresses over a lifetime. Moreover there are „master control points” that regulate molecular stress response. These „swichtes” might have consequences when using that Harries and her team are still workoing on. 

Stopping or reversing agening is truly unbelivable- although it is going to have many consequenses. However scientists are in some way simpler goal- to keep us healthier for longer as we age. First therapies are likely to reverse age ing in specific tissues, such as retina or joints. 

Prematurely- before the usual/normal time 

Rejuvenated- someone look or feel young and energetic again

Gradual- progressing slowly

               Scientists from Yale School of Medicine have made the biggest milestone in bringing brains back to life. They found out that a blood substitute called BrainEX is able to reboot some brain functions such as producing energy and remove waste. They are saying that the process of cell death can be postponed, preserved or even reversed. They reported that they had revived the brains of 32 pigs right after they have been killed. The found out that electrical activity of brain restarted, sadly there were no signs of consciousness whatsoever. To achieve that they have been asking themselves a lot of questions about death and the whole process of dying. 

               All in all, we are still far away from being immortal or bringing people back to life, but this is surely a big achievement and further research can be developed from it.

When scientists manage to obtain the samples, they plan to use a very specific method of research called imaging techniques such as helium-ion beam microscopy to thoroughly analyze the black matter which particles can be 1000 times thinner than a width of a human hair. 

Astrophysicists are hoping to get a founding to this huge project. If they receive one the first results will appear by 2025. But if not and they won’t find WIMPs everyone will be constrained to theorize again. Anyway, let’s hope for the best and keep our fingers crossed for solving one of the biggest mysteries of the world.

They do not understand cause and effect. They cannot properly link words such as “chair” or  “vehicle” to real physical objects, because they never experience reality how we do it. 

Over time computers might closer to us. Maybe people’s succeed programed computers to feel feelings, but the gap between us will likely always by there. Computers didn’t interrupt what people, maybe will never acquire  this skills

Children born couple weeks before the planned date of birth often die or suffer from many diseases. The construction of artificial womb is a hope to save such a premature child. Scientists from one of the Dutch universities have recently announced that they had received a lot of money to develop prototype of this invention. Already in 2017, scientists from Philadelphia transferred foetal lambs into a so-called biobag and animals developed correctly. Then in 2019 Australian Japanese research team did the same but with younger foetuses and in a different system. 

The Dutch group plans to introduce this prototype in five years, while the Australian doctor who worked on it in 2019 says it will take much longer. Previously created artificial womb can’t replace the real one. 

The article also presents the artificial womb as a helpful device for people who cannot get pregnant.

Despite the many benefits, some people believe this is associated with legal concerns and is not safe.

As we all know the brain is our most important organ, if it dies, we die. Without blood, your brain cells begin to die and after about 6 minutes you’re gone. But what if there was a way to bring back neurological function to your brain?

In 2020 scientists from Yale School of Medicine managed to successfully revive the brains of 32 pigs 4 hours after their death. This raised huge interest among neuroscientists, as death has been thought to be impossible to oppose for many centuries. The method they used to revive them was very creative. Basically, they linked the dead organs to a system that infused them with BrainEx, which is a blood substitute that helps preserve the brain’s structure and allows the brain cells to produce energy. Marvelously, the scientists noticed that the electrical activity between those cells had restarted. This definitely proves that some post-death processes can be delayed, preserved, and even reversed. So now we have to ask ourselves, what is the true definition of death, and should we keep the research going to possibly create at least some form of consciousness in the future?

This one specific thing is interesting for many material scientists, designers, engineers . Because it can grow on simply every type of waste you can think of and can get any shape wanted. They can even soak up toxic heavy metals and can grow on radioactive waste. That is unbelievable. 

Mycelium is now used to make many things such as lightweight plastic and some designers are also thinking of a way to make clothes, shoes, vases, lamps, tables and other products with positive environmental impact from them. 

What is unimaginable about mushrooms is that they may grow on Mars. That means that they would be able to make life out there. This would really change the world and if anything happens we would have somewhere else to live. 

 materials scientists - study the structures and chemical properties of various materials to develop new products or enhance existing ones.

no-brainer - something that requires or involves little or no mental effort.

fungi - any of a group of spore-producing organisms feeding on organic matter, including moulds, yeast, mushrooms, and toadstools.

hospitable - friendly and welcoming to visitors or guests.

biotechnology - the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.

an immense - extremely large or great, especially in scale or degree.

In order to achieve that, they hooked up the organs to a system called BrainEx, which infused them with a blood substitute, therefore, a cell recovery. Brains connected to the system maintained the internal structure and rebooted some brain cell functions. Though no signs of consciousness were discovered, they found that electrical activity between brain cells restarted. 

Lead researcher Prof Nenad Sestan stated that death is gradual and some processes can be postponed, preserved or even reversed. He began his journey on an animal’s brain to learn how it works. Now he’s planning on carrying out further studies on the subject, but is reluctant to say what his next steps are. 

The interest in brain studies increases, and it will not be surprising to see Frankenstein headlines in the 2020s.

infuse - fill, soak

reluctant - unwilling and hesitant

reboot - to start something again or do something again, in a way that is new and interesting

hook up - to connect

substitute - replacement

preserved - kept in its original state

With no blood supply your brain starts dying, and if your brain dies, you die as well. However, scientists from Yale School of Medicine found out that brain could be brought back to life. They proved this by reviving the brains of 32 pigs four hours after they been slaughtered. Reaserchers connected dead organs with blood substitute called BrainEx, which recovers cells after oxygen deprivation. Prof Nenad Sestan says that the process of cell death is gradual and it could be postponed, preserved or even reversed. Sestan began trying to revive animal brain cells to understand brain networks and neurological disease. He ended up raising scientifical and ethical questions like: „How do we define death?”. BBC Science Focus found out that he and his research group are planning next set of experiments but it would be premature to reveal the terms, however they are going experiment on the cats. 

To sum up, the death process turned out to be gradual and reversible. Moreover, it is might be the begining of discovering the key to longevity.

This year scientists from Yale school revived the brains of 32 pigs hours after they were considered as dead. They have connected those brains to a BrainEx system, which boosts the regeneration of cells that are lacking oxygen. This system also helps to recreate the main functions of brain, that are necessary to live. Researchers discovered, that after using BrainEx there is ongoing electrical activity between cells in brain, although there aren’t any coordinated signals, so also no consciousness.
Prof Nenad Sestan explained, that cell death occuring splits into some stages, and some of those lesser processed are possible to be postponed, preserved or reversed.
Sestan stared this project trying to revive an animal brain cell to investigate the brain networking and it’s neurological aspects, but eventually ended with a promising invention that may mean a lot during future researches.
Sestan contacted the BBC Science Focus, bur refuses to say what are their conclusions or how are the preparations for continuation of research going now. He has only revealed, that period of next investigations probably reaches distant future and it’s now impossible to tell anything more about upcoming experiments.
Regardless of Sestan’s team actions there are a lot of scientists who are willing to dig more in this discovery.

It is well known that when our brain dies, we die. The irreversible loss of vital functions takes place (within a period of 5min). The scientists from Yale School of Medicine worked out the experiment that resuscitate 32 pigs four hours after their death. They infused them with a blood substitute, that should regenerate cells after deficiency of oxygen, so the organs can work, but not as successfully as before. There is lack of awareness and coordinated signals. In April 2019 Prof Nenad Sestan submitted the results of his project, which causes many consequences. BBC Science Focus get in contacted with him. The team of Sestan’s scientists is working on another projects, but it is too soon to disclose them. In the mean time Italian neurosurgeon assure, that he’s ready to proceed first transplant of human head. The summing up sentence is – “Mostly dead is slightly alive”.

The article starts with basic information about death and how long does it take for your brain to die. The author describes the way, in which scientists managed to reverse death of a pig’s brain, four hours after it’s been slaughtered. The researchers hooked up the dead organs to a technology called BrainEx, which infused them with blood. It resulted in cell recovery after oxygen deprivation and the brain regaining some of its usual functions. Unfortunately the consciousness didn’t come back. Scientists stated off trying to understand brain networks and ended up bringing up a very ethical questions, such as: “How do we define death?”, “Are current guidelines on brain death in need of revision?” or “Should they even be conducting research that raises the smallest possibility of creating consciousness?”. The text also mentions Sergio Canavero - an Italian surgeon, who’s biggest dream is to conduct a first human head transplant.
