Popeye’s secret: spinach provides key insight that might one day lead to artificial photosynthesis

Tue, Jul 29, 2014


While scientists have been studying and incrementally increasing solar cell efficiency, we’ve yet to reach nature’s magnitude of solar energy conversion through photosynthesis. Artificial photosynthesis is a goal in alternative energy research, yet the process is extremely difficult to mimic since, in nature, the process involves numerous stages and transformation of matter and energy. Purdue University […]

Why your battery is dying – the answer could vastly improve battery life

Tue, Jul 29, 2014


If you’ve owned a smartphone or laptop for more than two years and use the gadgets frequently, then you’ve most likely noticed, to your exasperation, how short the battery life is compared to when the product was first shipped. Rechargeable batteries have been around for more than 100 years, but it’s only recently that scientists […]

Adding lithium makes graphite both transparent and conductive. A great game changer for the industry

Thu, Jul 3, 2014


Materials found in nature often speak of at least one comprise. Metals for instance are highly conductive, but not transparent. Plastics on the other hand can be made to be transparent, but they’re very poor electrical conductors. This annoying tradeoff has aggravated scientists for some time in their efforts to design better solar cells or […]

Addiction is a disease that first starts with dopamine overcorrection in the brain

Wed, Jul 2, 2014


Drug and alcohol addiction affects millions of people around the world, but despite decades worth of research and billions of dollars, our understanding of addiction is still far from being complete. Brigham Young University professor Scott Steffensen and his team have recently contributed with a few pieces in the addiction puzzle, which are of vital […]

Link found between nearsightedness and years spent in school

Fri, Jun 27, 2014


A common stereotype is that people who wear glasses are labeled as nerds, but sooner than later most people from the developed world will end up wearing glasses, if the current trend continues. There are many reasons why more and more suffer from nearsightedness, ranging from urbanization, spending more time indoors and in front of […]

Supernova study might change how speed of light in vacuum is measured

Wed, Jun 25, 2014


Einstein’s theories suggest that light can not travel faster than c, a constant equal to the speed of light in a vacuum, which is 299,792,458 metres per second (by definition) or about 186,282.4 miles per second. All of our standing physical models are based on this assumption, and so far this idea has yet to […]

People who excessively share on facebook are more lonely and depressed

Tue, May 27, 2014


Researchers at  Charles Sturt University in New South Wales found a connection between excessive sharing of information on facebook and feeling lonely and/or depressed. This is the latest in a slew of studies that suggest the social network can cause serious emotional damage to some people. The researchers found that 79 percent of users who describe themselves […]

Astrobiologists testify before Congress that alien life will be encountered by 2034

Mon, May 26, 2014


This past week, a few scientists took the bench and gave the U.S. Congress a relative date by which they expect we’ll have discovered signs of intelligent life elsewhere in the universe. According to their estimates, by 2034 we should make first contact or 30 years ahead of Star Trek’s first contact. Whether this was […]

Ultra-sensitive chip can detect cancer fast from only a drop of blood

Tue, May 20, 2014


Most cancer diagnosis tools and procedures today involve detecting the disease on the microscopic level. There is no single test that can accurately diagnose cancer. The complete evaluation of a patient usually requires a thorough history and physical examination along with diagnostic testing – a lot and a lot of tests. If that wasn’t enough, […]

There probably is no such thing as gluten intolerance, study shows

Wed, May 14, 2014


This is one of those science stories where it gives to show that even scientists can be biased and, most of all, that it’s only when you stand-up and become willing to contradict yourself that you come closer to the truth. Peter Gibson, a professor of gastroenterology at Monash University and director of the GI […]
