Did rapid spin delay 2017 collapse of merged neutron stars into black hole?
Continuing X-ray observations by Chandra of the kilonova from the merger of two neutron stars to form a black hole hint at new processes. Initially, a gamma-ray burst and subsequent X-ray emissions told of a jet of material produced by the merger, but …
COVID in a cat
A study has confirmed what is believed to be the first published account of the delta variant of SARS-CoV-2 in a house cat. The viral sequence was a close match to strains circulating in the Philadelphia area at the same time, underscoring the virus’s …
Mutations in SARS-CoV-2 spike protein receptor-binding domains may result in escape variants resistant to therapeutics and vaccines
The SARS-CoV-2 virus is continuously evolving and structural changes to the virus may impact the efficacy of antibody therapies and vaccines. A study describes the structural and functional landscape of neutralizing antibodies against SARS-CoV-2 spike …
Investigating the effects of critical illness in early childhood on neurocognitive outcomes
Approximately 23,700 children in the U.S. undergo invasive mechanical ventilation for acute respiratory failure annually. Although most survive, little is known if they have worse long-term neurocognitive function than children who do not undergo such …
Study finds lower oxidative stress in children who live and study near green spaces
A study has analyzed the relationship between exposure to different green spaces and oxidative stress in children. The study concluded that greater exposure to vegetation is associated with lower levels of oxidative stress and that this association is …
SARS-CoV-2-infected individuals could have different variants hidden in different parts of the body
People suffering from COVID-19 could have several different SARS-CoV-2 variants hidden away from the immune system in different parts of the body, finds new research. The study’s authors say that this may make complete clearance of the virus from the b…
Why multiple myeloma returns
Multiple myeloma, the most common type of bone marrow cancer in Germany, almost always returns, even after initial treatment success. In the majority of cases, the reasons behind this treatment resistance (e.g., genetic mutations) and the subsequent re…
For new insights into aerodynamics, scientists turn to paper airplanes
A series of experiments using paper airplanes reveals new aerodynamic effects, a team of scientists has discovered. Its findings enhance our understanding of flight stability and could inspire new types of flying robots and small drones.
Wild baboons sacrifice sleep to meet pressing demands
Sleep study on a troop of wild baboons reveals that sacrificing sleep to meet pressing demands is common — and might even be part of our evolutionary history.
Booster critical as COVID-19 vaccine-induced antibodies wane in 6 months, don’t protect against omicron, researchers find
A new study using serum from human blood samples suggests neutralizing antibody levels produced by two-dose mRNA vaccines against the original and early variants of the SARS-CoV-2 virus wane substantially over time, and offer essentially no protection …
These solar panels pull in water vapor to grow crops in the desert
Using a unique hydrogel, scientists have created a solar-driven system that successfully grows spinach by using water drawn from the air while producing electricity. The proof-of-concept design offers a sustainable, low-cost strategy to improve food an…
Bacteria genes gave ancient plants traits to colonize land
Genes jumping from microbes to green algae hundreds of millions of years ago might have driven the evolution of land plants, researchers report. Their analysis reveals that hundreds of genes from bacteria, fungi, and viruses have been integrated into p…
Machine learning improves human speech recognition
To understand how hearing loss impacts people, researchers study people’s ability to recognize speech, and hearing aid algorithms are often used to improve human speech recognition. Researchers explore a human speech recognition model based on machine …
Cloth masks inferior for protection against airborne viral spread
A new study examines the efficacy of particle filtration by woven fabric, which consists of fibers twisted together into yarns. There are, therefore, two lengthscales: the diameters of the fiber and the yarn. Using 3D imagery produced by confocal micro…
