Discovery of a Brown Dwarf Hotter than the Sun

Discovery of a space object hotter than the sun
Phased radial-velocity curves of WD 0032−317. a, trailed UVES spectrum for the H𝛼 line of WD 0032−317 (blue represents lower fluxes, and yellow represents higher fluxes), folded over the orbital period (𝑃 = 8340.9090 s). The primary absorption is clearly seen in blue. The emission from the companion (in yellow) appears in anti-phase with the primary, and is visible only from the irradiated day side, between orbital phases ∼ 0.2–0.8. Its “inverted” shape, evident especially near quadrature, is the result of non-local thermodynamic equilibrium (NLTE) effects [40]. b, radial velocity curves (top panel) of the white dwarf (blue circles) and the irradiated companion (red diamonds), folded over the orbital period (𝑃 = 8340.9090 s)...

Scientists develop Magnetically Controlled Soft Medical Robot inspired by the Pangolin

Pangolin the inspiration for medical robot
The pangolin-inspired untethered magnetic robot. A Conceptual illustration of the pangolin-inspired robot operating in the small intestine. Robot is actuated with a low-frequency magnetic field and heated remotely with a high-frequency magnetic field. The pangolin’s body consist of individual overlapping hard keratin scales. The robot inspired by this overlapping design is shown on the right. Images of pangolins used under Standard licence from Shutterstock. Credit: Max Planck Institute for Intelligent Systems Tübingen

Pangolins are fascinating creatures. This animal looks like a walking pine cone, as it is the only mammal completely covered with hard scales. The scales are made of keratin, just like our hair and nails...

Using data from the Spitzer space observatory, Dr. Susana Iglesias-Groth, a researcher from The Instituto de Astrofísica de Canarias (IAC), has found evidence for the existence of the amino acid tryptophan in the interstellar material in a nearby star-forming region. The research is published in Monthly Notices of the Royal Astronomical Society.

High amounts of tryptophan were detected in the Perseus molecular complex, specifically in the IC348 star system, a star-forming region that lies 1,000 light years away from Earth—relatively close in astronomical terms. The region is generally invisible to the naked eye, but shines brightly when viewed in infrared wavelengths.

Tryptophan is one of...

Elimination of Type of Bacteria Suggests Treatment for Endometriosis

A research group from the Graduate School of Medicine and iGCORE at Nagoya University in Japan, has discovered that using an antibiotic to target Fusobacterium reduced the formation of lesions associated with endometriosis, a gynecological disorder characterized by endometrial tissue usually found inside the uterus being found outside it. Their findings suggest an alternative treatment for this disorder. The study was published in Science Translational Medicine.

Endometriosis affects one in ten women between the ages of 15 and 49. The disorder can cause lifelong health problems, including pelvic pain and infertility...
