New semiconductor material AlYN promises more energy-efficient and powerful electronics

Posted by in categories: chemistry, energy, physics

Due to its excellent material properties and its adaptability to gallium nitride (GaN), AlYN has enormous potential for use in energy-efficient high-frequency and high-performance electronics for information and communications technology.

Aluminum yttrium nitride (AlYN) has attracted the interest of many research groups around the world due to its outstanding material properties. However, the growth of the material has been a major challenge. Until now, AlYN could only be deposited by magnetron sputtering.

Researchers at the Fraunhofer Institute for Applied Solid State Physics IAF have now succeeded in fabricating the new material using metal-organic chemical vapor deposition (MOCVD) technology, thus enabling the development of new, diverse applications.

‘Mirror’ nuclei help connect nuclear theory and neutron stars

Posted by in categories: nuclear energy, particle physics, space

Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom’s electrons, known as isotope shifts. Scientists can use precision measurements of these energy shifts to measure the radius of the nucleus of an isotope.

Coherence entropy unlocks new insights into light-field behavior

Posted by in categories: biotech/medical, internet

Light technology is at the heart of many cutting-edge innovations, from high-speed internet to advanced medical imaging. However, transmitting light through challenging environments, such as turbulent atmospheres or deformed optical systems, has always posed a significant hurdle. These complexities can distort and disrupt the light field, making it difficult to achieve clear and reliable results. Scientists have long sought ways to overcome these limitations, and a new breakthrough may hold the key to advancing practical applications.

Cricket physics: Wind tunnel experiments reveal why bowling with a near horizontal arm makes for tough batting

Posted by in category: physics

Key to winning a cricket match is tricking the other team’s batters—no small feat, as bowlers bowl cricket balls nearly 100 miles per hour. In recent years, a bowling technique that has become popular involves keeping the arm almost entirely horizontal during delivery, notably used by Sri Lankan stars Lasith Malinga and Matheesha Pathirana. The aerodynamics of such deliveries have perplexed sports physicists.

New massive eccentric brown dwarf discovered

Posted by in category: space

An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a highly eccentric orbit. The finding was detailed in a paper published August 8 on the pre-print server arXiv.

Engineering Toxoplasma gondii secretion systems for intracellular delivery of multiple large therapeutic proteins to neurons

Posted by in categories: biotech/medical, engineering, neuroscience

Bracha et al.


Toxoplasma gondii culture and maintenance.

Type I RH and type II Pru and ME49 strain T. gondii were grown in HFF in high-glucose Dulbecco’s modified Eagle’s medium (DMEM) supplemented with 4 mM l-glutamine, 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin or 20 μg ml−1 gentamicin antibiotics (‘complete DMEM’) at 37 °C with 5% CO2. Cultures were monitored daily and T. gondii were passaged by transferring 1–3 drops (20–100 μl) of the supernatant of a lysed dish (containing extracellular parasites) into a fresh dish with confluent HFF cells. Type I RH and type II Pru strains were validated by PCR–restriction-fragment length polymorphism (primers described in Supplementary Table 1)81 or by passage into Cre Reporter cell lines to confirm Cre recombination as previously described16.
