Recycled Li-ion batteries made with alfalfa seeds and pine resin

By - October 2, 2014 1 Picture
Thanks to their high power ratings and relative reliability, lithium-ion (Li-ion) batteries are an efficient and reliable source of power, widely used in modern electronic equipment. On the downside, however, expired Li-ion batteries are also difficult to dispose of, with their potentially toxic content and the complex methods required for their recycling. Researchers at Uppsala University’s Ångström Laboratory think that they may have a solution: combine the salvaged remnants of a Li-ion battery with completely organic materials derived from alfalfa and pine resin, to create a recycled biomaterial Li-ion hybrid battery.

Scientists make "Impossible Material" ... by accident

By - July 30, 2013 7 Pictures
In an effort to create a more viable material for drug delivery, a team of researchers has accidentally created an entirely new material thought for more than 100 years to be impossible to make. Upsalite is a new form of non-toxic magnesium carbonate with an extremely porous surface area which allows it to absorb more moisture at low humidities than any other known material. "The total area of the pore walls of one gram of material would cover 800 square meters (8611 sq ft) if you would 'roll them out'", Maria Strømme, Professor of Nanotechnology at the Uppsala University, Sweden tells Gizmag. That's roughly equal to the sail area of a megayacht. Aside from using substantially less energy to create drier environments for producing electronics, batteries and pharmaceuticals, Upsalite could also be used to clean up oil spills, toxic waste and residues.

Researchers alleviate PTSD in mice while they sleep

By - October 19, 2012 1 Picture
Though often associated with exposure to war, Post-Traumatic Stress Disorder (PTSD), is a severe anxiety disorder which can arise following exposure to any event which has caused psychological trauma. Those who suffer from PTSD are often subjected to re-living the source of their despair through nightmares and flashbacks, and current treatment results in only occasional success. However, researchers at Stanford University appear to have alleviated PTSD in mice while the rodents slept, by using a new technique which may prove applicable for humans in the future. Read More

Fear can be erased from the brain before its memory has been formed

By - October 5, 2012 2 Pictures
An old saying tells us not to dwell on an unpleasant event. A new clinical study suggests the saying has both psychological and neurological support for its validity. Along with his advisors, Thomas Ågren – a doctoral candidate in psychology at Uppsala University in Sweden – has shown that it is possible to erase newly formed emotional memories from the human brain.

Koenigsegg upgrades the Agera R to 1140 bhp (and plans to attempt 273 mph/440 km/h top speed run)

By - March 9, 2012 33 Pictures
Already one the world's fastest cars, the Koenigsegg Agera R has been reworked for the 2013 model year, raising peak horsepower from 1115 to 1140 bhp, giving it a top speed of 440 km/h (273.4 mph) - Koenigsegg intends to prove it sometime soon. The world's fastest production car is the Bugatti Veyron Super Sport at 431 km/h. Lots of new features in the new car. Read More

World's first hard X-ray free-electron laser images intact viruses

By - February 7, 2011 4 Pictures
An international team of scientists has obtained the world’s first single-shot images of intact viruses – a technology that could ultimately lead to moving video of molecules, viruses and live microbes. The team was also able to successfully utilize a new shortcut for determining the 3D structures of proteins. Both advances were achieved using the world’s first hard X-ray free-electron laser – the Linac Coherent Light Source (LCLS) – which scientists hope could revolutionize the study of life. Read More

Algae used to create a quick-charge, lightweight battery

By - September 13, 2009 2 Pictures
Algae blooms are unpleasant and unpredictable phenomena that arise quickly and strike seas and oceans, often causing serious problems to local ecosystems. But, in an effort to try and find a use for such algae, a research team from Uppsala University, Sweden, has recently managed to design a record-breaking "green" lightweight battery that is incredibly easy to produce and might just even out the environmental consequences of these blooms.
