Four crewmembers at the International Space Station (ISS) enjoyed a short ride aboard SpaceX’s Crew Dragon Endeavour on Saturday, moving the spacecraft to a different port to make way for a cargo ship arriving in June.

SpaceX Crew-6 members Stephen Bowen and Woody Hoburg of NASA, along with Sultan Alneyadi of the United Arab Emirates and Andrey Fedyaev of Russia, undocked from the Harmony module’s space-facing port at 7:23 a.m. before flying the short distance to the same module’s forward port.

Stinging of Hymenoptera can induce IgE-mediated hypersensitivity reactions in patients with venom allergies, ranging from local to severe systemic reactions and even fatal anaphylaxis. Allergic patients’ quality of life can be primarily improved by injecting increased venom doses to alter their immune response to tolerate venom. This venom-specific immunotherapy is very effective and well tolerated, especially in the administration of vaccines. Creative Biolabs is a world leader in the field of vaccine development. With our extensive experience and advanced platform, we are therefore confident in offering the best vaccine development services for allergic disease.

Creative Biolabs provides vaccine development services for bee venom allergy according to customer’s detailed requirements.

Floating life (neuston) is a core component of the ocean surface food web, but the Sargasso Sea in the North Atlantic is the only known region of high neustonic abundance. This study reveals high densities of floating life in the plastic-rich Great Pacific Garbage Patch, suggesting that this area could be an important marine habitat.

A new low-temperature growth and fabrication technology allows the integration of 2D materials directly onto a silicon circuit, which could lead to denser and more powerful chips.

Researchers from MIT

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.

With the advantages of scalability, enhanced performance and cost-effectiveness, cloud platforms have evolved as a substitute for legacy data warehouses and data lakes. Data warehouse modernization is often the top priority for businesses in present times.

According to Gartner, by 2025, 95% of digital workloads will be hosted in the cloud, which means almost all of us are busy building our cloud migration strategy. However, when developing a seamless cloud migration strategy, people often overlook ETL migration or treat it as an afterthought. This is where you unintentionally invite problems with performance and costs. If you fail to modernize your ETL processes, your company’s analytical data platform could be doomed.

Optical AI chips have struggled to implement a crucial algorithm used to train neural networks–backpropagation. But in a new paper in the journal Science, a team from Stanford University has described the first ever implementation of the training approach on a photonic chip.

A new kind of 3D optical lattice traps atoms using focused laser spots replicated in multiple planes and could eventually serve as a quantum computing platform.

Researchers have produced 3D lattices of trapped atoms for possible quantum computing tasks, but the standard technology doesn’t allow much control over atom spacing. Now a team has created a new type of 3D lattice by combining optical tweezers—points of focused light that trap atoms—with an optical phenomenon known as the Talbot effect [1]. The team’s 3D tweezer lattice has sites for 10,000 atoms, but with some straightforward modifications, the system could reach 100,000 atoms. Such a large atom arrangement could eventually serve as a platform for a quantum computer with error correction.

3D optical lattices have been around for decades. The standard method for creating them involves crossing six laser beams to generate a 3D interference pattern that traps atoms in either the high-or low-intensity spots (see Synopsis: Pinpointing Qubits in a 3D Lattice). These cold-atom systems have been used as precision clocks and as models of condensed-matter systems. However, the spacing between atoms is fixed by the wavelength of the light, which can limit the control researchers have over the atomic behavior.

Twenty years ago, Ferenc Krausz, Theodor Hänsch, and their collaborators used a femtosecond near-infrared (NIR) laser to compel neon atoms to emit pulses of extreme ultraviolet (XUV) light that lasted a few hundred attoseconds. The landmark feat depended on the laser’s strong oscillating electric field, which tore away the atoms’ valence electrons and hurled them back half a cycle later. Now Tobias Heldt of the Max Planck Institute for Nuclear Physics in Germany and his collaborators have developed a new experimental technique that is, in a sense, a mirror image of the 2003 demonstration: they used attosecond XUV pulses to free the valence electrons and to then track their response to femtosecond NIR laser pulses [1].

When a few-cycle femtosecond NIR pulse passes through helium gas, the atoms’ dipole moments fluctuate as the electrons move away and then recollide. Those fluctuations in turn are manifest in the gas’s absorption spectrum. Heldt and his collaborators set out to measure the fluctuations and, from them, infer the electrons’ trajectories.

The attosecond XUV pulse in their experiment did double duty. It ionized the helium atoms to bring the electrons under the influence of the NIR pulse. It also interfered with the fluctuating dipole moments. As a result, the XUV pulse carried away the dipoles’ spectral imprint, which the team measured with a grating spectrometer.
