A new study has helped scientists settle a long-standing mystery of why popcorn makes the popping sound.

The French team settled the question of why popcorn pops through a series of high-speed camera observations, sound recordings and the theory of thermodynamics, the Guardian reported.

Harvard scientists have created a system that uses bacteria to convert solar energy into a liquid fuel.

The work integrates an “artificial leaf,” which uses a catalyst to make sunlight split water into hydrogen and oxygen, with a bacterium engineered to convert carbon dioxide plus hydrogen into the liquid fuel isopropanol.

“This is a proof of concept that you can have a way of harvesting solar energy and storing it in the form of a liquid fuel,” said Pamela Silver, Professor of Biochemistry and Systems Biology at Harvard Medical School (HMS).

If you love getting high, bad news for you, as scientists have found a significant link between cannabis use and the onset and exacerbation of mania symptoms.

Mental health researchers from Warwick Medical School conducted a review of scientific literature examining the effect of cannabis use. The literature sampled 2,391 individuals who had experienced mania symptoms.

A new study has recently revealed that menacing crocodiles are fun loving animal too as they also take pleasure in activities like piggyback rides, surfing waves and playing ball.

Research by a psychology professor at the University of Tennessee, Knoxville, has shown a softer side of the intimidating creatures, one that includes romping around with river otters and people. The findings could shed light on how intelligence has evolved.

An international study has documented one of the most rapid biological transitions ever with the extinction of a unique New Zealand penguin and its replacement by another breed.

Study leaders from the University of Otago said Tuesday that the team used carbon dating and ancient DNA analysis of archaeological penguin remains to determine that the process happened within just a few decades.

A new study has recently revealed that heart of Earth has its own “inner core.”

With the help of novel application of earthquake-reading technology, a research team at the University of Illinois and colleagues at Nanjing University in China have found that the Earth’s inner core has an inner core of its own, which has surprising properties that could reveal information about our planet .

A new research has revealed how magicians sway decision-making.

A team of researchers from McGill University has combined the art of conjuring and the science of psychology to demonstrate how certain contextual factors can sway the decisions people make, even though they may feel that they are choosing freely, a finding with potential implications even for daily decision-making.

A new study has found that serotonin-deficient brains are more vulnerable to social stress.

According to a Duke study, following exposure to stress, mice genetically deficient in serotonin did not respond to a standard antidepressant, fluoxetine (Prozac), which works by boosting serotonin transmission between neighboring neurons.

Neil Armstrong’s wife has discovered long-lost historic Apollo 11 mission’s artifacts after 40 years, it has been revealed.

The bag full of power cables and utility clamps may not have looked very interesting when Carol Armstrong found them stuffed in a closet in her Ohio home, the Independent reported.

Yet the items, which had lain hidden for more than four decades, were actually priceless mementos from the most famous space mission of all, during which her husband became the first person to walk on the Moon.

A new research has revealed that human languages exhibit a clear positive bias across cultures far and wide, suggesting that people use more positive than negative words.

A team of scientists at the University of Vermont and The MITRE Corporation the researchers found that movie subtitles in Arabic, Twitter feeds in Korean, the famously dark literature of Russia, websites in Chinese, music lyrics in English and even the war-torn pages of the New York Times and probably all human language, skew toward the use of happy words.

The US space agency has released a stunning video revealing the far side of the Moon that cannot be seen from the Earth.

Using data from the Lunar Reconnaissance Orbiter (LRO), NASA’s scientific visualisation studio produced a video of the far side that shows that there are many more and larger craters than on the side which faces the Earth.

What it does not have is large dark spots called maria.

Although “dark” is a misnomer, the side of the Moon humans cannot see is illuminated by the Sun in just the same way as the Earth.

Now you can test the possibility of developing dementia with a prick of a needle.

As opposed to cardiovascular diseases, where the level of cholesterol in our blood indicates the risk of cardiac arrest, there are no such trustworthy markers in our blood in terms of diagnosing the risk of dementia setting in. However, Scientists at Rigshopitalet, Herlev Hospital and the University of Copenhagen have now identified a new biomarker, measurable in a simple blood test, which will help predict the onset of dementia.

Scientists from the University of Southampton have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in man-made underwater vehicles.

Scientists have built a deformable octopus-like robot with a 3D printed skeleton with no moving parts and no energy storage device, other than a thin elastic outer hull.

Researchers have discovered a peptide that may hold cure for TBI, heart attack as well as stroke.

Strokes, heart attacks and traumatic brain injuries are separate diseases with certain shared pathologies that achieve a common end – cell death and human injury due to hypoxia, or lack of oxygen. In these diseases, a lack of blood supply to affected tissues begins a signaling pathway that ultimately halts the production of energy-releasing ATP molecules – a death sentence for most cells.
