Small biodegradable circuits for the release of painkillers inside the body

August 9, 2019

Patients with orthopedic prostheses usually experience severe pain after surgery. To relieve pain, the surgeon injects painkillers into the tissue during surgery. When this disappears a day or two later, the patient is given morphine through a catheter near the spine.

Researchers found ALMA Dives into Black Hole’s Sphere of Influence

August 8, 2019

Latest observations with Atacama Large Millimeter / Submillimeter Array (ALMA) giving an unprecedented close-up view of a cold interstellar spinning disk spinning around a supermassive black hole. This disc is located in the center of NGC 3258 a giant elliptical galaxy around 100 million light years from Earth.

A new study found the dead planets can shine for up to a billion years

August 8, 2019

In a recent study from the University of Warwick, scientists identified the best candidates for finding relics on planets, based on the possibility of stars hosting the planet’s core that is still alive and the strength of radio signals that we can rely on. This study examines the survival of planets orbiting white dwarfs, stars […]

Entropy explains the degree of diffusion of RNA in cells

August 8, 2019

Recent studies have shown that in yeast cells and bacteria, the diffusion rates of complex RNA-protein molecules, which transmit important information into cells, are distributed in a typical exponential model. As it turns out, these models show the highest level of perturbation or entropy of all possible diffusion processes in cells.

The Synthesizing of single crystalline hexagonal graphene quantum dots emit blue light

August 8, 2019

Researchers have developed a new strategy for the synthesis of single-crystal quantum dots that emit stable blue light. The research team confirmed that the display of quantum dots of graphene which he synthesized succeeded in emitting blue light with a stable electric pressure, reportedly overcoming the long-standing challenge of blue light on the screens produced.

Astronomers thinks maybe the dark matter is warm not cold

August 8, 2019

Astronomers are aware that dark matter is the dominant component of matter in the universe. However, it greatly influenced the evolution of galaxy structures and the distribution of cosmic microwave background radiation (CMBR). Extraordinary agreement between the values of important spatial parameters such as the rate of expansion.

The Moon is Older Than Scientists Previously Thought

August 7, 2019

New research by scientists at the University of Cologne’s Institute of Geology and Mineralogy shows that the moon is older than the giant impact hypothesis itself. Their research is based on a chemical analysis of Apollo’s moon samples and shows that the moon only forms 50 million years after the solar system, isn’t it 150 […]
