The Burj Khalifa in Dubai currently holds the title of world’s tallest building, but its architects are now looking to overtake it with a new project in Saudi Arabia. Known as the Jeddah Tower, or Kingdom Tower, the building will rise at least 3,280 feet when it’s completed in 2018, making it the world’s first to reach a full kilometer into the air. (The Burj Khalifa is 2,716 feet tall.) This week, the Saudi government announced that $2.2 billion in funding had been secured to build Jeddah City, including the tower.

The tower was designed by Adrian Smith + Gordon Gill Architecture, and construction up to the 26th floor has already been completed. But there’s still a lot to be done. When completed, the $1.23 billion project will have 200 floors that will be used for offices, apartments, and a Four Seasons hotel. It will also overlook the Red Sea, which posed engineering challenges due to the nearby saltwater and high wind levels. That explains its deep, 200-foot foundations, and its angular, wind-shielding shape.

Smith and Gill say they also incorporated some of the design language from the Burj Khalifa, with its moat and cluster of surrounding towers. “Its specific form comes more from the image of a new palm about to spread its fronds,” Smith told The Guardian earlier this year.

Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air.

Phases are distinct forms of the same material. Graphite is one of the solid phases of ; diamond is another.

“We’ve now created a third solid phase of carbon,” says Jay Narayan, the John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State and lead author of three papers describing the work. “The only place it may be found in the natural world would be possibly in the core of some planets.”

A ‘head-up’ display for passenger vehicles developed at Cambridge, the first to incorporate holographic techniques, has been incorporated into Jaguar Land Rover vehicles.

Cambridge researchers have developed a new type of head-up display for vehicles which is the first to use laser holographic techniques to project information such as speed, direction and navigation onto the windscreen so the driver doesn’t have to take their eyes off the road. The – which was conceptualised in the University’s Department of Engineering more than a decade ago – is now available on all Jaguar Land Rover vehicles. According to the researchers behind the technology, it is another step towards cars which provide a fully , or could even improve safety by monitoring driver behaviour.

Cars can now park for us, help us from skidding out of control, or even prevent us from colliding with other cars. Head-up displays (HUD) are one of the many features which have been incorporated into cars in recent years. Alongside the development of more sophisticated in-car technology, various companies around the world, most notably Google, are developing autonomous cars.

Well if we do have a major SHTF event even though we don’t have many skilled tool makers any more. Then at least the remains of society should be able to teach itself tool making.

A new study from the University of Exeter has found that teaching is not essential for people to learn to make effective tools. The results counter established views about how human tools and technologies come to improve from generation to generation and point to an explanation for the extraordinary success of humans as a species. The study reveals that although teaching is useful, it is not essential for cultural progress because people can use reasoning and reverse engineering of existing items to work out how to make tools.

The capacity to improve the efficacy of tools and technologies from generation to generation, known as cumulative culture, is unique to humans and has driven our ecological success. It has enabled us to inhabit the coldest and most remote regions on Earth and even have a permanent base in space. The way in which our cumulative culture has boomed compared to other species however remains a mystery.

It had long been thought that the human capacity for cumulative culture was down to special methods of learning from others — such as and imitation — that enable information to be transmitted with high fidelity.

Engineers at the University of California, San Diego developed a new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood. The technology could serve as a general tool to separate and recover nanoparticles from other complex fluids for medical, environmental, and industrial applications.

Nanoparticles, which are generally one thousand times smaller than the width of a human hair, are difficult to separate from plasma, the liquid component of blood, due to their small size and low density. Traditional methods to remove from typically involve diluting the plasma, adding a high concentration sugar solution to the plasma and spinning it in a centrifuge, or attaching a targeting agent to the surface of the nanoparticles. These methods either alter the normal behavior of the nanoparticles or cannot be applied to some of the most common nanoparticle types.

“This is the first example of isolating a wide range of nanoparticles out of plasma with a minimum amount of manipulation,” said Stuart Ibsen, a postdoctoral fellow in the Department of NanoEngineering at UC San Diego and first author of the study published October in the journal Small. “We’ve designed a very versatile technique that can be used to recover nanoparticles in a lot of different processes.”

Cornell biomedical engineers have developed specialized white blood cells they call “super natural killer cells” that seek out cancer cells in lymph nodes with only one purpose: to destroy them, halting the onset of cancer tumor cell metastasis.

“We want to see lymph-node metastasis become a thing of the past,” said Michael R. King, the Daljit S. and Elaine Sarkaria Professor of Biomedical Engineering and senior author of a paper in the journal Biomaterials.

The G-Cans project is the largest flood protection in the world. Its official name is Metropolitan Area Outer Underground Discharge Channel, but it is most known as G-Cans Underground Temple because of its support pillars and interior that reminds the visitor of a giant cave. The purpose of this facility is to protect the city of Tokyo from floods. The northern edge of G-Cans touches Kasukabe, a city located in Saitama Prefecture, 30 km north of Tokyo. The necessity of building such facility originated from the danger of overflowing of the rivers and main waterways during typhoons and rain periods.

I had read about Singapore in genetic engineering way back in the 90’s. I think they were 1st or 2nd in making immortal skin cells at the time.

Singapore scientists have unravelled a mystery that could pave the way for turning back the clock on ageing.

A recent study led by Dr Ng Shyh Chang of the Genome Institute of Singapore at the Agency for Science, Technology and Research (A*Star) has found a gene in human egg cells that suppresses an enzyme causing cells to age.

This is the Tcl1 gene, and by increasing the protein it produces, the researchers found they could suppress the enzyme that causes mitochondria — the cells’ batteries — to age over time.

There’s filtration and then there’s filtration. Engineers in the US have been working on the latter, coming up with a new markedly more energy-efficient way of taking the salt out of seawater, which could deliver huge advantages in terms of providing people with access to drinking water and help combat problems like drought.

The researchers have developed a material that allows high volumes of water to pass through extremely tiny holes called ‘nanopores’ while blocking salt and other contaminants. The material they’re using – a nanometre-thick sheet of molybdenum disulphide (MoS2) riddled with these nanopore holes – is the most efficient of a number of thin-film membranes that the engineers modelled, filtering up to 70 percent more water than graphene.

“Even though we have a lot of water on this planet, there is very little that is drinkable,” said Narayana Aluru, a professor of mechanical science and engineering at the University of Illinois and leader of the study. “If we could find a low-cost, efficient way to purify sea water, we would be making good strides in solving the water crisis.”
