X-ray binary GX 3+1 investigated with AstroSat
Using the AstroSat spacecraft, Indian astronomers have investigated a low-mass X-ray binary known as GX 3+1. The study provided more insights into the properties of GX 3+1 and detected a thermonuclear burst from this source. The findings are reported.....»»
Dying stars" cocoons could be new source of gravitational waves
So far, astrophysicists have only detected gravitational waves from binary systems—the mergers of either two black holes, two neutron stars or one of each. Although astrophysicists theoretically should be able to detect gravitational waves from a s.....»»
New study explains interaction between quantized vortices and normal fluids
Osaka Metropolitan University scientists investigated numerically the interaction between a quantized vortex and a normal fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that.....»»
Study investigates the behavior of X-ray binary GX 349+2
Using the AstroSat spacecraft and the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), Indian astronomers have observed an X-ray binary known as GX 349+2. Results of the observational campaign, publish.....»»
Decline in wealth due to commission ban in Europe estimated at 375 billion euros annually

Gravitational-Wave Search Resumes after Three Years and Lots of Headaches
Researchers still hope to discover hundreds of new binary black hole mergers despite technical setbacks that have sidelined key detectors in Italy and Japan.....»»
For the first time, astronomers have detected a radio signal from the massive explosion of a dying white dwarf
When stars like our sun die, they tend to go out with a whimper and not a bang—unless they happen to be part of a binary (two) star system that could give rise to a supernova explosion......»»
Reading comprehension not worsened by noise, study finds
Researchers of the HSE Centre for Language and Brain have investigated the impact of both auditory and visual noise on semantic processing during reading to determine if it results in a more superficial reading style that emphasizes the meanings of i.....»»
MeerKAT radio telescope catches a "Mini Mouse" in the sky
Using the MeerKAT radio telescope, European astronomers have serendipitously discovered a new radio nebula during observations of the black hole binary GRS 1915+105. The newfound object, dubbed "the Mini Mouse," is a young radio pulsar escaping its b.....»»

The Clinic for Animal Reproduction, Faculty of Veterinary Medicine, Freie Universitaet Berlin in Germany, has investigated the intensive molecular changes that take place during dog pregnancy......»»
Jaw shapes of 90 shark species show evolution driven by habitat
An international research team led by Faviel A. López-Romero from the Department of Paleontology at the University of Vienna investigated how the jaw shape of sharks has changed over the course of evolution. They conclude that in the most widespread.....»»
Blazar 1ES 1959+650 investigated with Swift and XMM-Newton satellites
Using NASA's Swift observatory and ESA's XMM-Newton satellite, Indian astronomers have inspected a prominent high synchrotron peaked blazar known as 1ES 1959+650. Results of the study, published May 5 on the arXiv pre-print server, shed more light on.....»»
Nitrogen addition and mowing alter drought resistance and recovery of grassland communities
The effects of increased nitrogen input and mowing on the resistance and recovery of temperate grassland experiencing a three-year natural drought (from 2015 to 2017) were investigated based on a five-year field manipulative experiment......»»

Dodging justice: Characteristics of repeat child sex offenders
Many crimes are obvious, with those responsible soon apprehended, but with most sexual abuse (including child sexual abuse) remaining unreported or undetected, Griffith University researchers have investigated the characteristics of repeat offenders.....»»
Researchers describe mechanisms that could prevent infections with the influenza A and Ebola viruses
Viruses like influenza A and Ebola invade human cells in a number of steps. In an interdisciplinary approach, research teams from Heidelberg University and Heidelberg University Hospital investigated the final stages of viral penetration using electr.....»»
Star-forming activity in the interacting galaxy system NGC 5291 investigated with AstroSat
An international team of astronomers have employed India's AstroSat spacecraft to observe a system of interacting galaxies known as NGC 5291. Results of the observational campaign, published April 6 in the Monthly Notices of the Royal Astronomical So.....»»
Researchers investigate the role of long-chain fatty acids in cellular respiration
Cellular respiration is a complex and highly regulated process that allows cells to draw energy from nutrition. An international team of scientists in Finland, Germany and Poland have investigated the important role of long-chain fatty acids in guidi.....»»
