Short-Period Hot Jupiter Discovered Circling HAT-P-68

Posted on

Astronomers using data from the HATNet (Hungarian-made Automated Telescope Network) survey have discovered a transiting giant planet orbiting the K5-type dwarf star HAT-P-68. “The discoveries of planets with orbital periods shorter than 10 days provide advantages to resolving current theoretical challenges in the field,” said University of Washington astronomer Bethlee Lindor… […]

New Antibiotics Fight Multidrug-Resistant Gram-Negative Bacteria

Posted on

A group of compounds called IspH inhibitors are very potent against several multidrug-resistant Gram-negative bacteria, including those from the genera Acinetobacter, Pseudomonas, Klebsiella, Enterobacter, Vibrio, Shigella, Salmonella, Yersinia, Mycobacterium and Bacillus, and are elatively non-toxic to mammalian cells, according to new research from the Wistar Institute. A metabolic pathway called methyl-D-erythritol… […]

Is All Dark Matter in Universe Made of Primordial Black Holes?

Posted on

In a new paper in the journal Physical Review Letters, an international team of theoretical physicists described a scenario for the formation of primordial black holes from vacuum bubbles in the early Universe and discussed its intriguing realization that can naturally account for all of the dark matter. Primordial black holes… […]

Weddell Seals Can Produce Ultrasonic Vocalizations: Study

Posted on

Marine biologists from the University of Oregon and the University of New Brunswick have recorded common, previously unknown, ultrasonic vocalizations produced by Weddell seals (Leptonychotes weddellii), the world’s southernmost-ranging mammal. They’ve identified nine recurrent call types in more than one year (2017-2018) of broadband acoustic data obtained by a continuously recording… […]

Discovery boosts theory that life on Earth arose from RNA-DNA mix

Posted on

Chemists have made a discovery that supports a surprising new view of how life originated on our planet. They demonstrated that a simple compound called diamidophosphate (DAP), which was plausibly present on Earth before life arose, could have chemically knitted together tiny DNA building blocks called deoxynucleosides into strands of primordial… […]
