Could adding extra dimensions help solve the quantum gravity puzzle?

Posted by in categories: particle physics, quantum physics

Adding extra dimensions to a theory known as “fuzzy gravity” may help bridge the gap between quantum mechanics and relativity.

A recent study has made strides toward solving one of physics’ biggest puzzles: including all known particles and interactions into the theory of quantum gravity.

The solution is to modify the quantum description of gravity dubbed “fuzzy gravity” by introducing extra dimensions to spacetime. In this theory, spacetime is treated not as a continuous entity but by a grid of discrete points, and adding extra dimensions to this grid results in the occurrence of other fields and particles.

Scientists hope a new take on superconductivity could spark more advances in the field

Posted by in categories: computing, particle physics, quantum physics

Understanding this unique form of superconductivity is crucial and could lead to exciting applications, like functional quantum computers.

A newly synthesized material made from rhodium, selenium, and tellurium, has been found to exhibit superconductivity at extremely low temperatures.

“The scientists believe the material’s behavior might stem from the excitation of quasiparticles — disturbances within the material that behave like particles — making it a ” topological” superconductor. This is significant because these quasiparticles’ quantum states could potentially be more resilient, remaining stable even when the material or its environment changes.

Diamond helps build efficient 3D computer chips

Posted by in category: computing

Tackling heat transfer, diamond layers help build 3D circuits with lower power consumption, faster signaling, and increased performance.

Scientists have discovered that adding diamond layers to computer chips significantly boosts heat transfer, paving the way for faster, more powerful computers.

Their research revealed that this combination improves heat transfer by tenfold, a feat that could lead to more efficient designs like 3D circuits, where electronic components are stacked vertically, and heterogeneous integration, which combines different types of components in a single chip.

Magnetic fields from the beginning of time may resolve the Hubble tension

Posted by in category: space

By adding primordial magnetic fields to the Standard Model, researchers may solve the mystery of the Universe’s expansion.

Scientists have suggested a way to resolve a longstanding paradox known as the Hubble tension by taking primordial magnetic fields into account, which may have been generated in the early moments of the Universe.

“Primordial magnetic fields are the fields generated in the early Universe, such as during inflation, phase transitions, and other processes,” explained Yaoyu Li, a physicist at the Purple Mountain Observatory in China and one of the authors of the study. “These magnetic fields might evolve with the expansion of the Universe, be amplified and subsequently become galactic magnetic fields that we observe today.”

Report: Global drought threatens food supplies and energy production

Posted by in categories: energy, food, sustainability

In July 2024, global temperatures reached unprecedented levels, breaking historical records with an average of 17.16°C. This extreme heat has led soil water to evaporate, leaving the vegetation and biodiversity more fragile and under stress in many regions of the world.

Vision loss: Is gene therapy the answer?

Posted by in categories: biotech/medical, genetics, health

Diseases that affect the retina, the light-sensitive layer at the back of the eye, are a significant cause of visual impairment and blindness. Gene therapy holds promise for treating some of these conditions, and current research advances may soon shift the therapeutic landscape for eye health. However, many obstacles remain in place, as this Special Feature discusses.

Gene therapy uses genetic material, either DNA or RNA, to treat or prevent the progression of a disease. It often involves the introduction of genetic material into a person’s cells to replace a defective or missing gene.

Although early attempts at gene therapy have been effective in achieving the expression of the therapeutic gene in the target tissue, they have also been accompanied by severe adverse effects.

NASA Sets Coverage for Europa Clipper Launch to Jupiter Moon

Lee esta nota de prensa en español aquí.

NASA will provide live coverage of prelaunch and launch activities for Europa Clipper, the agency’s mission to explore Jupiter’s icy moon Europa. NASA is targeting launch at 12:31 p.m. EDT Thursday, Oct. 10, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Beyond Earth, Jupiter’s moon Europa is considered one of the solar system’s most promising potentially habitable environments. After an approximately 1.8-billion-mile journey, Europa Clipper will enter orbit around Jupiter in April 2030, where the spacecraft will conduct a detailed survey of Europa to determine whether the icy world could have conditions suitable for life. Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission. It carries a suite of nine instruments along with a gravity experiment that will investigate an ocean beneath Europa’s surface, which scientists believe contains twice as much liquid water as Earth’s oceans.
