AX J1949.8+2534 is a supergiant fast X-ray transient, observations confirm

Based on the results from a set of telescopes, astronomers detected X-ray variability of the source AX J1949.8+2534 and confirmed that the object is a supergiant fast X-ray transient (SFXT). The finding is reported in a paper published April 22 on the arXiv pre-print repository.

The space rock that hit the moon at 61,000 kilometers an hour

Observers watching January's total eclipse of the Moon saw a rare event, a short-lived flash as a meteorite hit the lunar surface. Spanish astronomers now think the space rock collided with the Moon at 61,000 kilometres an hour, excavating a crater 10 to 15 metres across. Prof Jose Maria Madiedo of the University of Huelva, and Dr. Jose L. Ortiz of the Institute of Astrophysics of Andalusia, publish their results in a new paper in Monthly Notices of the Royal Astronomical Society.

Here's a hypothetical: a telescope detects an asteroid between 100 and 300 meters in diameter racing through our solar system at 14 kilometers per second, 57 million kilometers from Earth.

Dark matter exists: Observations disprove alternate explanations

As fascinating as it is mysterious, dark matter is one of the greatest enigmas of astrophysics and cosmology. It is thought to account for 90 percent of the matter in the universe, but its existence has been demonstrated only indirectly, and has recently been called into question. New research conducted by SISSA removes the recent doubts on the presence of dark matter within galaxies, disproving the empirical relations in support of alternative theories. The study, published in the Astrophysical Journal, also offers new insights into understanding the nature of dark matter and its relationship with ordinary matter.

Astronomers discover 2,000-year-old remnant of a nova

For the first time, a European research team involving the University of Göttingen has discovered the remains of a nova in a galactic globular cluster.

Alzheimer's in minibrains

In the majority of cases, dementia can be traced back to Alzheimer's disease. Its causes are not really understood yet. What is known is that plaques form from misfolded proteins and that there is an increase in neuronal cell death levels in the brain. However, the plaques don't necessarily go hand in hand with any symptoms. Dr. Thorsten Müller, Head of the research group Cell Signalling at the Chair of Molecular Biochemistry at Ruhr-Universität Bochum (RUB), suspects other deposits to cause the disease, namely ones that form in the nuclei. He intends to verify this hypothesis using tissue that resembles that of the brain. Rubin, the RUB's science magazine, published a report on his research.

Breaking open the gates of antibiotic resistance

Antibiotic resistance is a major health threat, with about two million people in the US getting an antibiotic-resistant infection per year, according to the Centers for Disease Control and Prevention (CDC). Gram negative bacteria, including types like E.coli and Salmonella, are often more difficult to kill because of their two-pronged defenses—they have two membranes rather than one, and also have numerous toxin pumps embedded in the membranes to expel any antibiotic that may have made it through. Now Jefferson researchers have uncovered how to target both of these defenses with one hit, which could help make antibiotics more effective.

US cities host more regionally unique species than previously thought

Scientists are analyzing a rare snapshot in time of urban plants and animals. To better understand whether rapidly growing cities are hosting the same species, a concept known as urban homogenization, a team from the California Academy of Sciences analyzed an immense volume of data gathered by citizen scientists during the four-day global City Nature Challenge. The 14 U.S. cities included in the study amassed more than 65,000 wildlife observations identified to species level through the mobile app iNaturalist. Study findings suggest that despite similarities across cities, urban biodiversity still strongly reflects the species that are native to a region. However, observations of shared "cosmopolitan" species like pigeons, white-tailed deer, and dandelions were more numerous than locally occurring species. The study, published today in the journal PeerJ: Life & Environment, highlights the value of citizen science data in addressing complex questions about rapid changes in urban ecology.
