Ashkin was awarded for the invention of “optical tweezers” that grab particles, atoms, viruses and other living cells without damaging them, while Mourou and Donna were given the honour for creating the ultrashort high-intensity laser pulses.
Following the most precise test of gravity outside the Milky Way, an international team of astronomers has confirmed the validity of Albert Einstein’s general theory of relativity in another galaxy.
Famed theoretical physicist Stephen Hawking’s last theory about our universe which he worked on with Professor Thomas Hertog from KU Leuven, is based on string theory and it suggests that the universe is finite and much simpler, as compared to many other current theories on the big bang.
Stephen Hawking, one of the greatest theoretical physicists, has died at his home in Cambridge. He was 76. At the age of 21, Hawking was diagnosed with amyotrophic lateral sclerosis (ALS), a rare neurodegenerative disease commonly known as Lou Gehrig's Disease. It left him wheelchair-bound and totally paralyzed.
Light is made of individual photons, and these particles do not usually interact with each other. But a team of physicists from MIT and Harvard have successfully made three photons interact to create a new form of light - a breakthrough that could open a path toward using photons in quantum computing.
If you push something, it will move in the direction of force applied. But if you push an object with negative mass, it will move against the direction of applied force. Creating a particle with negative mass seems practically impossible. But now physicists have developed a device that can create particles with negative mass.
The first-ever observation of cataclysmic collision of two ultra-dense neutron stars, which generated infinitesimal ripples in the fabric of space and time called gravitational waves, has been voted the biggest Scientific Breakthrough of the year 2017.
Physicists have proven the existence of new form of matter called excitonium, almost 50 years after it was first theorized. Upon studying non-doped crystals of the transition metal dichalcogenide titanium diselenide (1T-TiSe2), the researchers were able to observe the material and its precursor soft plasmon phase called the "smoking gun" that proves the existence of this rare, exotic material.
Lightning is one of the most incredible natural phenomenons and there’s a lot we don’t know about it. Now, a study at Kyoto University, Japan has found that lightning strikes can set off photonuclear reactions in the atmosphere, and the gamma rays - emitted in lightning - react with the air to produce radioisotopes and even positrons (or, anti-electrons) - the antimatter partner of electrons.
