Reaching the quantum ground state of sound in waveguides: Scientists move a step closer

Posted by in categories: particle physics, quantum physics

A team of scientists at the Max Planck Institute for the Science of Light led by Dr. Birgit Stiller has succeeded in cooling traveling sound waves in waveguides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the ultimate goal of reaching the quantum ground state of sound in waveguides.

Unwanted noise generated by the acoustic waves at can be eliminated. This experimental approach both provides a deeper understanding of the transition from classical to quantum phenomena of and is relevant to quantum communication systems and future quantum technologies.

The quantum ground state of an acoustic wave of a certain frequency can be reached by completely cooling the system. In this way, the number of quantum particles, the so-called acoustic phonons, which cause disturbance to , can be reduced to almost zero and the gap between classical and bridged.

Watch: Asteroid turns into fireball before crashing into Earth in Germany

Posted by in category: space

A small asteroid entered Earth’s atmosphere Sunday morning and lit up the sky over eastern Germany. Videos of the incident have gone viral on social media, depicting a glowing object descending over Europe. Experts later confirmed that the light came from a disintegrating meteorite.

According to astronomers and observers, the 2024 BX1 asteroid, which was temporarily designated as Sar2736, landed outside Berlin near Nennhausen at around 1:30 am local time. Hungarian astronomer Krisztián Sárneczky was the first one to discover the approaching asteroid several hours before its impact, according to The International Astronomical Union.

RSV shown to Infect Nerve Cells, cause Inflammation and Damage

Posted by in category: biotech/medical

Respiratory syncytial virus (RSV), a common infection in children and senior adults, can also infect nerve cells and trigger inflammation leading to nerve damage, according to a new Tulane University study.

RSV can cause mild symptoms such as coughing, sneezing and fever or lead to more severe conditions such as pneumonia or bronchiolitis.

But since the disease was first discovered in 1956, it has been thought to only infect the respiratory tract.

Unlocking the secrets of the universe through neutrinoless double beta decay

Posted by in category: particle physics

The discovery that neutrinos have mass was groundbreaking. However, their absolute mass remains unknown. Neutrinoless double beta decay experiments aim to determine whether neutrinos are their own antiparticles and, if so, provide a means to determine the mass of the neutrino species involved.

Determining the mass through neutrinoless double beta decay experiments using 76 Ge is only possible if scientists understand the properties of the decay of 76 Ge into selenium-76 (76 Se). A study published in Physical Review C provides key input for these kinds of experiments.

Germanium-based neutrinoless double beta decay (0νββ) experiments hold great promise for unraveling the mysteries surrounding neutrinos. The observation of this rare decay process not only offers the prospect of determining the nature of these enigmatic particles, but also the determination of their , provided the probability governing the decay is reliably known.

Cobalt-free batteries could power cars of the future

Posted by in categories: finance, sustainability, transportation

Many electric vehicles are powered by batteries that contain cobalt — a metal that carries high financial, environmental, and social costs.

MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries).

In a new study, the researchers showed that this material, which could be produced at much lower cost than cobalt-containing batteries, can conduct electricity at similar rates as cobalt batteries. The new battery also has comparable storage capacity and can be charged up faster than cobalt batteries, the researchers report.

A new drug candidate can shrink kidney cysts

Posted by in category: biotech/medical

Autosomal dominant polycystic kidney disease (ADPKD), the most common form of polycystic kidney disease, can lead to kidney enlargement and eventual loss of function. The disease affects more than 12 million people worldwide, and many patients end up needing dialysis or a kidney transplant by the time they reach their 60s.

Researchers at MIT and Yale University School of Medicine have now found that a compound originally developed as a potential cancer treatment holds promise for treating ADPKD. The drug works by exploiting kidney cyst cells’ vulnerability to oxidative stress — a state of imbalance between damaging free radicals and beneficial antioxidants.

In a study employing two mouse models of the disease, the researchers found that the drug dramatically shrank kidney cysts without harming healthy kidney cells.

The Green Spark: A Catalyst Transforming Water Into Energy Wealth

Posted by in categories: energy, sustainability

A stable, reactive, and cost-effective ruthenium catalyst for sustainable hydrogen production through proton exchange membrane water electrolysis.

Sustainable electrolysis for green hydrogen production is challenging, primarily due to the absence of efficient, low-cost, and stable catalysts for the oxygen evolution reaction in acidic solutions. A team of researchers has now developed a ruthenium catalyst by doping it with zinc, resulting in enhanced stability and reactivity compared to its commercial version. The proposed strategy can revolutionize hydrogen production by paving the way for next generation electrocatalysts that contribute to clean energy technologies.
