Aevum’s autonomous aircraft will deliver cargo and occasionally launch rockets

The company says space launch is only going to be a part-time job for Ravn X. WASHINGTON — Space launch startup Aevum on May 18 revealed that its Ravn X unmanned aircraft will be used to both deliver cargo and launch rockets, pending approval from the Federal Aviation Administration.  The Alabama-based company on May 4 received a patent for an “adaptive autonomous aircraft system with modular payload systems,” a technology that would allow Ravn X to be converted from a space launcher to a cargo delivery aircraft and vice versa. Before receiving this patent, Aevum had been vague about its

Solar Orbiter Images First Coronal Mass Ejections – See the Stunning Videos From Multiple Instruments

Combining imagery from three of Solar Orbiter’s remote sensing instruments – the Extreme Ultraviolet Imager (EUI), the Metis coronagraph, and Solar Orbiter’s Heliospheric Imager (SoloHI) – provides both close-up and wide views of the evolution of a coronal mass ejection (CME) on February 12-13, 2021. CMEs are eruptions of particles from the solar atmosphere that blast out into the Solar System. First Solar Orbiter movies showing coronal mass ejections (CMEs) A pair of CMEs were detected by multiple instruments during February’s close flyby of the Sun CMEs are eruptions of particles from the solar atmosphere that blast out into the

New Fixed-Wing Aircraft to Connect Suburbs and Cities

German eVTOL (electric vertical take-off and landing) company Volocopter designed a new fixed-wing aircraft specifically designed for suburb-to-city commutes, the company announced in a press statement on Monday, May 17. The VoloConnect is a four-seater aircraft with a range of 62 miles (approx. 100km), making it especially suited to “connect suburbs to cities” and complement “the company’s existing family of aircraft for the intra-city mission,” the company said in its statement. Volocopter explained that the VoloConnect aircraft’s hybrid lift and push design is expected to be certified within the next 5 years.

Cooking a Levitating Hot Dog in Mid-Air With Science

A levitating hot dog cooker that looks straight out of a Harry Potter movie is the invention you never thought you needed: Inspired by science host Bruce Yeany, Ben of NightHawkInLight uses an 80-gallon air compressor and a heat coil to accomplish the remarkable feat of getting the hot dog to dance in mid-air in this video. Ben uses a nichrome and copper coil and ditches the blowtorch to cook the hot dog, improving on Yeany’s compressed air levitation. At first glance, the video might seem bizarre; but before you judge it too quickly, have you ever thought about what

Scientists Found a Quasicrystal From a 1945 Nuclear Explosion

Researchers from the Los Alamos National Laboratory (LANL), which was founded during WWII for the design of nuclear weapons as part of the Manhattan Project, discovered a new quasicrystal created by the first-ever nuclear explosion at Trinity Site, New Mexico, on July 16, 1945. Their findings are published in the journal PNAS. The authors of the study stated that new discovery frames the quasicrystal’s creation by a nuclear weapon in the context of physical processes carried out over hundreds of millions of years in deep space. The material sample could, therefore, help future generations to better understand the chain of events set

Bacteria Colonize Our Gut During and After Birth, New Study Shows | Biology, Medicine

An international team of researchers from Germany and Canada has investigated whether bacteria could be detected in prenatal stool (meconium) samples. Kennedy et al. found that fetal gut colonization of healthy term infants does not occur before birth. Image credit: Darryl Leja, National Human Genome Research Institute, National Institutes of Health. Microbial colonization of the human intestine is a key developmental process since the order and timing of microbial exposure shape the development of the gut microbiome and impact host metabolism and immunity later in life. In humans, maturation of both intestinal barrier function and immunity occurs prenatally. The fetal

Novel intelligent vehicles to monitor water source safety for 2022 Winter Olympic Games

A water quality monitoring unmanned surface vehicle helps to improve the reservoir water environment. Credit: Yu Daoyang As the 2022 Beijing Winter Olympic Games are approaching, it’s a high priority to guarantee the water quality of Guanting Reservoir, one of the water resources of the Games. Recently, researchers from the Institute of Solid State Physics (ISSP), Hefei Institutes of Physical Science (HFIPS), and their collaborators developed a water quality monitoring unmanned surface vehicle, which has been put into trial operation in Guanting Reservoir. “We… Continue Reading News Source:

Grazing management of salt marshes contributes to coastal defense

Cow grazing enhanced this erosion resistance by compacting the soil by trampling. Credit: University of Groningen Combining natural salt marsh habitats with conventional dikes may provide a more sustainable and cost-effective alternative for fully engineered flood protection. Researchers of the University of Groningen (UG) and the Royal Netherlands Institute for Sea Research (NIOZ) studied how salt marsh nature management can be optimized for coastal defense purposes. They found that grazing by both cattle and small herbivores such as geese and hare and artificial mowing can reduce salt marsh erosion, therefore contributing to nature-based coastal defense. … Continue Reading News Source:

A meta-analysis of elective coronary revascularization vs. medical therapy alone

Credit: Unsplash/CC0 Public Domain A rigorous meta-analysis of randomized clinical trials (RCTs) that compared the effects of medical therapies alone with medical therapies plus revascularization in patients with stable ischemic heart disease (SIHD) was presented at EuroPCR on May 18, 2021. The study concluded that adding revascularization was associated with a statistically important reduction in cardiovascular death associated with a statistically important reduction in spontaneous myocardial infarction (MI), providing a biologically plausible explanation for the observed benefit. … Continue Reading News Source:
