The world population is predicted to reach 12.3 billion by 2100. Previous claims had stated that population growth would stabilize and the number of people on Earth would plateau by 2100,but new research has stated that increased fertility rates and life expectancy, particularly in Africa, is the reason for the rise.As a result, renewed population policies may have to be proposed.
Renewable energy gets a boost
A new type of battery has been made that could be invaluable to future renewable energy production. The lithium-antimony-lead liquid metal battery has the ability to store vast amounts of electricity. Utilising a negative electrode, the battery has a much lower operating temperature than previous designs and will maintain around 85 per cent of its original efficiency even after a decade of daily use.
Scientists create a shape-shifting metal
Scientists have created a new type of liquid metal. Formed from an alloy of gallium and indium, the material has a bright future and is being predicted to self-repair electronic structures and circuits. A liquid at room temperature, the alloy is the shape of a ball, but goes flat when exposed to voltage
New truck will save lives
Senior lecturers from Lough borough University have designed a new type of lorry that could save cyclist and pedestrian lives. The new-look cab will eliminate blind spots and increase the driver’s fi eld of vision. The model created by the team will have a cab that is 80 centimetres (31.5 inches) longer with a more rounded front. The emphasis will be on sight with a smaller dashboard but larger and more windows.
There’s a new treatment to regenerate bones
Osteoporosis a condition that weakens bones–could be combated by an injection of calcium phosphate. This paste will contain stem cells encased in microspheres. Stem cells of ten struggle to survive when entering the body,but the casing will aim to safely transport the cells to the bones.
All-electric Formula E begins
Electric racing cars took to the streets of Beijing as the first-ever Formula E Championship began.The first of its kind, the competition will look to provide the same thrill ride as Formula 1, but without the carbon emissions. It will run until June 2015.
Brains have their own (free) ‘calorie counters’
Our brains naturally works out the calorie content of different foods when we look at a menu. That’s according to neuro imaging research, which sought to determine how our awareness of calories infl uenced the brain. The study found that although calorie estimations were off the mark, people were willing to pay high prices for high-calorie food, showing their desire to consume it.
There are three types of Europeans
New research has suggested that the European different peoples:blue-eyed hunters,brown-eyed farmers and an in flux of groups from Siberia.The findings were discovered by analysing genomes and shows that Europe was originally an area of blue-eyed hunter-gatherers before the arrival of brown-eyed farming communities from the east around 7,500 years ago.
We could build a lift to space
A real stairway to heaven could be made in the future using the extraordinary properties of diamond nano threads. The new material was developed by researchers at Penn State University, USA and is composed of a string of carbon atoms. Created under extreme pressure, the nano thread is extremely tough and one of the main hopes for the breakthrough is to create a space-lift system.
There’s a new trip to Mars
The latest NASA mission to Mars is named MAVEN and took ten months to reach Martian orbit. The satellite’s task will be to monitor the planet’s atmosphere in an attempt to find out why it is so devoid of air. MAVEN will look to find out what effects the Sun has had on the Red Planet’s climate throughout history and why Mars has lost all of its water.
