Does Universe Iterates Through Infinite Numbers of Big Bangs?

conformal cyclic cosmology.

Researchers created nearly 5,000 simulations to find evidence of conformal cyclic cosmology.  The probability of finding new points (Hawking Points) in cosmic microwave background is less than 1/5000. Roger Penrose, a mathematical physicist, sees quantum mechanics in a different way. He is definitely not a big fan of the concept that universe underwent a quick ...

Gold Nanoparticles Can Enhance Solar Energy Storage

Enhance Solar Energy Storage

Gold nanostars could help increase solar energy use and combat climate change. When coated with a semiconductor, they produce hydrogen from water 4 times more efficiently than previous demonstrations. Colloidal gold nanoparticles have been used for decades due to their vibrant color producing capabilities after being introduced to visible light. These unique optoelectronic characteristics are now ...

The First Comprehensive Measurements Of Particle Beam

Measurements Of Particle Beam

A new method generates the first measurement of all 6 parameters of a particle beam.  This will help scientists build efficient, high-powered particle accelerators.  Particle accelerators are machines that use electromagnetic fields to propel charged or neutral particles to near speed of light. They are used in several fields, including high-energy physics research and cancer treatment. ...

New Class Of Endoscopic Imaging Catheter To Better Identify Diseases

new class of Endoscopic Imaging Catheter with metalens

A new form of endoscopic imaging catheters, named nano optic endoscopes are far efficient than existing catheters.  They could be used in any complex medium to obtain high-quality focusing and detect diseases, including cancer.  Diagnosing internal organ diseases mostly relies on biopsy samples taken from infected areas. However, the existing endoscopic imaging methods cannot precisely ...

WB5: A New Superhard Material With Exceptional Mechanical Properties

new superhard material

Researchers predict a new material made of tungsten boride, named WB5.  The material is thermodynamically stable at zero pressure and zero Kelvin temperature.  It has a 45 GPa of Vickers hardness and can possess nearly 4 MPa * m0.5 of fracture toughness.  Substances that have Vickers hardness greater than 40 GPa are called superhard material. Most superhard ...

A Model That Makes Stock Trading Behavior Comprehensible

anterior insular cortex regions

Researchers have built a new model for analyzing stock trading behavior.  It shows that the anterior insular cortex regions of the brain are more active among individuals who do not buy stocks.  Despite huge profit expectations in long-term, most people do not prefer to invest their hard-earned money in the stock market. Can you guess, ...

Scientists Levitate A Magnetic Stir Bar While It Rotates In A Fluid

levitating magnetic bar

Researchers discovered a technique of levitating a magnetic bar while it spins in a fluid.  This insight could aid in the design of bidirectional fluidic pumps and artificial swimmers. Levitation is a method of suspending something in stable mechanical equilibrium against gravity with the help of electric, magnetic or acoustic fields. Finding simple and inexpensive ...

Is It Possible To Learn Something New While You’re Sleep?

Learn Something New While You're Sleep

Human brain perceives sounds during sleep, but it’s unable to group these sounds in an appropriate sequence.  Scientists used magnetoencephalography to prove that speech cannot be recognized during non-rapid and rapid eye movement sleep.  The ability to learn during sleep, known as hypnopedia, was popularized in the late 1950s. It’s an attempt to convey information through ...

Cancer Treatment Could Be Improved By Using Game Theory

Cancer Treatment Could Be Improved

Researchers examined cancer treatment as a game played by the physician and tumor cells.  The physician, as a leader in the game, can regularly monitor cancer responses during each treatment cycle. This approach combined with a mathematical model could provide useful data to enhance the results of subsequent cycles.  Cancer can be treated by radiation therapy, ...
