Dark Energy Makes Time Move Forward

What is dark energy, and what does it cause in the universe? A new study published in Physical Review E has attempted to answer this very question. Dark energy remains elusive to the world of science. What is known is that it seems to have the opposite effect to gravity: it pushes space apart. Furthermore,

Interaction Between Earth and Sun Magnetic Fields Documented

Did you know that the magnetic field of the Earth and that of the sun interact with each other? While ours is meant to protect us from the latter, the interplay between the two can still lead to explosions in space, and can even affect our planet’s surface. A new study published in the journal

Quantum Spin Liquid – New State of Matter Discovered

A new state of matter has been spotted in a two-dimensional material called alpha-ruthenium that bears resemblance to graphene. It has been named “quantum spin liquid” state, and is said to come together with strange fermions. The findings are published in Nature Materials. The quantum spin liquid had been predicted by scientists decades ago; it

Pendulum Clock Synchronisation Mystery Sheds Light on Heart Beating

Unveiling the mystery of two pendulums synchronising could help understand biological rhythmic phenomenons like heart beating and breathing. The paper describing this relationship is published in the journal Scientific Reports. Why do pendulum clocks placed on the same wall influence each other such that a synchrony between them will be brought about after a certain

Electrical Current Applied In Brains Of Stroke Patients Boosts Their Recovery

Applying an electrical current to the brain of a stroke patient might boost his recovery, says a new study published in the journal Science Translational Medicine. The study focuses on the technique known as transcranial direct current stimulation (TDCS) with respect to rehabilitation training. TDCS entails the application of a low electrical current through the

Using Laser Weapon To Shield Earth From Asteroid Impacts

Scientists propose the use of laser weapons to shield the Earth from asteroid impacts. The possibility of asteroids impacting the Earth has kept some scientists busy with finding ways to avert such hazards. One such concept has recently been put in the spotlight: using a laser weapon to protect the planet from killer asteroids. Shielding

Mysterious Cause of Lightning Formation Revealed

The mysterious cause of lightning formation has  been discussed in a new paper. The unprecedented observations are documented in a paper published in Nature Communications. Scientists have delved further into the mystery of the formation of lightning. While it is established that lightning is an electric current flowing in the midst of a cloud, or between a cloud

World’s Thinnest & Lightest Solar Cells Developed by MIT Researchers

MIT researchers have invented super-thin and flexible solar cells that can convert light energy from the sun to electricity. The findings are published in the journal Organic Electronics. The thinnest (one-fiftieth the thickness of a human hair) and lightest solar cells have been developed by MIT researchers. They can be used on any material, from

In Depth: Time Actually Behaves Like A Crystal – Here’s How

Time has remained an evasive topic. The more scientists attempt to unveil its secrets, the more it gets away from their grasp. Some physicists have even questioned how we perceive its very existence: a team of researchers have investigated the very structure of time and claim that it behaves like a crystal. Their revised paper is
