Researchers from Australia's nuclear science agency have suggested that the unique immune system of alpacas could help in curing coronavirus.
The Australian Nuclear Science and Technology Organization (ANSTO) and Walter and Eliza Hall Institute (WEHI) said on Tuesday that they are studying alpaca antibodies in the search for therapies for COVID-19, reports Xinhua.
By immunising alpacas with the spike protein from SARS-CoV-2, researchers have been able to isolate nanobodies and screen them for the ability to inhibit the virus.
They have then been able to use the Microfocus Crystallography (MX2) Beamline at ANSTO's Australian Synchrotron to study how an alpaca's immune system can fight infection by COVID-19.
Michael James, ANSTO's Australian Synchrotron senior principal research scientist, said the Synchrotron - a type of particle accelerator - has also been used to study human proteins responsible for the replication of the virus within cells and the structure of the virus that causes COVID-19.
"Since March, we've been operating a COVID-19 Rapid Access program to enable Australian and international researchers to solve the atomic structure of SARS-CoV-2 viral proteins," he said in a statement.
"We're looking at proteins either by themselves or bound to other biological molecules or anti-viral drugs that can help fight the virus or prevent its spread. In this instance, MX2 is being used to determine the structure of these inhibitory nanobodies in complex with the key region of the spike protein to understand the structural mechanism of inhibition," James said.
"These structures will provide invaluable information that will allow further development of antibody therapies against COVID-19."
Japanese giant Toshiba will not make PCs or laptops as it has sold its final stake in the personal computer maker Dynabook.
Sharp bought 80% of Toshiba's personal computing arm in 2018 for $36m (£27m), and has now bought the remaining shares, Toshiba said in a statement.
Toshiba's first laptop, the T1100, was launched in 1985 only in Europe with an annual sales target of 10,000 units, according to website of Toshiba Science Museum, reports BBC.
In 2011 Toshiba sold more than 17m PCs but by 2017 this had fallen to 1.9m, reported Reuters.
In 2016, it had ceased making consumer laptops for the European market, focusing only on hardware for businesses.
Recent years have been difficult for the conglomerate as in 2015, it posted a full year loss of $318m, later in 2019, it wrapped up its nuclear business NuGen in UK after failing to find a buyer for it.
Consumer demand for laptops has soared in the last few months because of the Coronavirus pandemic and global lockdowns, but overall, the market for personal computers has been tough for quite a while, said analyst Marina Koytcheva from the firm CCS Insight.
The adventure-loving persons are getting bored during the pandemic situation. What if, you can feel the thrill of adventure in the virtual world? Try Minecraft! Released in 2011, this sandbox video game was developed by Mojang Studios. Though this game was initially designed for personal computers, now it is compatible with diverse platforms. For its versatile gaming interface and creative design, Minecraft has acquired its position among the top-selling video games worldwide. Around 126-million people are playing this game around the world every month in 2020. In this article, we are going to discuss some beginner tips and tricks for the Minecraft game. Stay with Us!
If you are playing the Minecraft Pocket Edition, you have to choose between two game modes: Creative or Survival. Pick the one which suits your personality.
In the ‘Survival’ mode you find a 3D interface. This random setting won’t give you any provisions. In this gaming mode, you have to start the hunt for mining with limited health. The enemies or hostile mobs would come out after sunset. To survive and excavate treasure, you have to act skillfully.
On the other hand, the ‘Creative’ mode offers you the opportunity to build the world of your own using diverse crafty items, architectural techniques as well as unlimited resources. Unlike the survival mode, in creative mode, you don’t need to be bothered about enemy attacks!
In the world of Minecraft, you can be whatever you desire to be. Isn’t it exciting? From the settings, you can choose your virtual character browsing the provided options of ready-made skins. What if, you do not like the pre-built skins and want to design a unique character? Thanks to Minecraft designers for allowing the players to customize their own characters following respective dreams. Certainly, you can play this video game with both fun and creativity.
In the Minecraft game, each player needs to collect resources for survival. Initially, you have to start gathering resources from your nearby places. For instance, you can collect wood, stone, or even dirt. You can easily gather resources by tapping and holding on a specific block. Try to collect resources at your best capacity. During the quest for resources, do not forget that you have to survive at any cost.
Home is your shelter where you can stay safe from enemies and take rest for the whole night until sunrise. Try to find a suitable place covering about two by two or one by three grid area to build your home. It is wise to create a simple home, instead of drowning energy and time in building a luxury one.
Your safe-house can be placed at mountain-side, small cube, or ground-hole. Apply available materials like wood, dirt, or stone to build your shelter. You can keep some open space on the roof portion of your home for watching the first rays of the sun.
While staying in your home, you can start crafting in no delay. By virtue of crafting skills, you would be able to create handy items that would facilitate your survival and excavation journey. Utilizing the inventory tools and gathered resources, you can create different items. Initially, the inventory offers you a four by four grid area. Now choose the wood and create plank. Then decide what kind of item you do require. For example, to build a crafting table, select a three by three grid area. Thus, getting skilled you can dare to build advanced items like tools, weapons, and armors.
Remember one thing that your enemies can appear only during the darkness. In order to guard your home, you can arrange torches. Try to place the torches sporadically around your safe house. Maintaining some distance among the torches, you can illuminate the surrounding space of your shelter. Thus, you can prevent the aggressive mobs from attacking your home and nearby area. However, the enemy can still roam around that place.
After sunset, do not waste all your energies in fighting the enemies. A healthy sleep during the nighttime can keep your body energetic for the next day's adventure. Try to craft a cozy bed for placing inside your sweet virtual home. Sleep may not be so easy in real life. But in Minecraft, all you need to do is to tap on the bed and you fall into sleep.
Health is wealth. The Minecraft game won’t let you forget it even in the virtual world! In this game, Food is considered an essential resource that restores the player’s health; especially when he gets injured. However, managing food requires some skills and hard work too. First, you need to hunt fish or animals (like cows, or chickens). Then cook the meat using a furnace. If you love farming, then grow diverse grains, vegetables, or fruits. You can also bake a cake or other delicious food.
You would find the real taste of adventure while excavating mines. Most of the precious treasures are hidden under the ground area. Like real life, you have to work hard to acquire those resources. On the journey of hunting, you would need diverse tools. First, craft essential tools like an ax. Then start the process of tunneling down utilizing the stair-like pattern.
It would be wise to carry torches wherever you move. If you find any resources, try to collect it. While searching the dungeon, caves, or mines, stay safe from the probable dangers like poisonous water or burning lava. Another essential thing this you have to know the pros and cons of different kinds of resources like wood, gold, or metal.
Australian researchers have developed a technology that can turn seawater safe to drink in less than 30 minutes by using only a high-tech filter and direct sunlight.
According to the Melbourne-based Monash University, the specially-designed filter is capable of generating hundreds of litres of drinkable water per day, reports Xinhua.
The technology requires only direct sunlight to purify, making the process energy-efficient, low-cost and sustainable.
Metal-organic frameworks (MOFs), a class of compounds consisting of metal ions that form a crystalline material with the largest surface area of any material known, are used in making the filters.
During the desalination process, a functionalised MOF filter firstly adsorbs salt from water, which consumes no energy, then the salt filled MOF can be put under sunlight to regenerate, taking less than four minutes, before it can absorb salt from water again.
Lead author of the research, Professor Huanting Wang from the Department of Chemical Engineering at Monash University, said desalination is a feasible option to address the pressing water shortage crisis around the world.
Desalination has been used to address escalating water shortages globally.
Due to the availability of brackish water and seawater, and because desalination processes are reliable, treated water can be integrated within existing aquatic systems with minimal health risks," Wang said.
"But thermal desalination processes by evaporation are energy-intensive, and other technologies, such as reverse osmosis, have a number of drawbacks, including high energy consumption and chemical usage in membrane cleaning and dechlorination."
With low energy consumption and no chemicals needed during the process, Wang said this highlights the durability and sustainability of this new technology for future clean water solutions.
"This study has successfully demonstrated that the photoresponsive MOFs are a promising, energy-efficient, and sustainable adsorbent for desalination," he said.
