Dr. Rupert Sheldrake believes that memory is inherent to nature, and has spent the last forty years of his career investigating slippery, esoteric phenomena at the very edges of empiricism. Some of the results are intriguing — dogs that know when their owners have started the long journey home, crosswords that become easier to solve a few days after they’ve been published in the papers, IQ scores increase generation after generation. His work is ongoing, the territory marginal, and the implications immense.

The experimental realization of a recently proposed technique points to new possibilities for imaging molecules using x rays.

Hanbury Brown and Twiss (HBT) interferometry [1] is a versatile technique widely used in various fields of physics, such as astronomy, quantum optics, and particle physics. By measuring the correlation of photon arrival times on two detectors as a function of the photons’ spatial separation, HBT interferometry enables the determination of the size and spatial distribution of a light source. Recently, a novel x-ray imaging technique based on the HBT method was proposed to image the spatial arrangement of heavy elements in a crystal or molecule by inducing those elements to fluoresce at x-ray wavelengths [2].

A new study published in The Astrophysical Journal Letters.

The Astrophysical Journal Letters (ApJL) is a peer-reviewed scientific journal that focuses on the rapid publication of short, significant letters and papers on all aspects of astronomy and astrophysics. It is one of the journals published by the American Astronomical Society (AAS), and is considered one of the most prestigious journals in the field.

Morphological study of open clusters can provide observational evidence for tracing the formation mechanism of star clusters and help to explore the evolution of star clusters.

The morphology of open clusters on the two-dimensional (2D) projection planes mostly conforms to the core-shell structure. However, whether this layered structure actually exists in three-dimensional (3D) space is not known.

Recently, researchers from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences proposed a rose diagram overlaying method based on Gaia data to study the 3D layered structure of open samples within 500 parsec (pc) near the sun.

Tesla received a large order for Model 3s from an Emirati taxi company, Arabia Taxi Dubai, helping the company to cut its carbon footprint.

Tesla’s retail consumer pressure is undeniably large. Still, the automaker has also grown in popularity in the commercial space, especially from customers looking to cut operating costs while reducing their carbon footprints. Predominantly, these orders have been coming from ride-hailing companies and car rental services. Now, a Dubai-based taxi company is also looking to capitalize on the cut-cutting opportunity.

According to the announcement from Arabia Taxi Dubai, it will buy 269 Tesla Model 3s to become part of its taxi fleet in the United Arab Emirates. Currently, Arabia Taxi advertises itself as the largest taxi fleet in Dubai and one of the largest in the country. With this new purchase, it looks to double down on that lead.

As well as showing Deimos in more detail — including the first images of its far side — insights have been gained about its makeup and structure. The new observations challenge the longstanding theory that Mars’ moons are captured asteroids, and instead point to a planetary origin. In other words, both Deimos and Phobos likely came from Mars itself, possibly ejected from a large impact.

The science team behind the Emirates Mars Mission has revealed ground-breaking imagery and data that advances our understanding of Deimos.

Deimos is one of the two small moons of Mars, the other being Phobos. Discovered in 1,877, and named after the Ancient Greek god of terror, this rocky and irregularly shaped moon has a mean radius of 6.2 km (3.9 mi) and orbits at 23,500 km (6.9 Mars radii), making it the smaller and outermost natural satellite.

Using the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST), astronomers from the University of Padua, Italy, and elsewhere have observed a metal-poor globular cluster known as Messier 92. The observations deliver crucial information regarding multiple stellar populations in this cluster. Results were published April 12 on the arXiv pre-print server.

Studies show that almost all (GCs) exhibit star-to-star abundance variations of light elements such as helium (He), oxygen (O), nitrogen (N), carbon © and calcium (Na). This indicates self-enrichment in GCs and suggests that are composed of at least two stellar populations.

Located some 26,700 away in the constellation of Hercules, Messier 92 (or M92 for short) is a GC with a metallicity of just-2.31 and a mass of about 200,000 . The cluster, estimated to be 11.5 billion years old, is known to host at least two stellar generations of stars—named 1G and 2G. Previous studies have found that Messier 92 has an extended 1G sequence, which hosts about 30.4% of cluster stars, and two distinct groups of 2G stars (2GA and 2GB).
