More than 15 years after the discovery of fast radio bursts (FRBs) – millisecond-long, deep-space cosmic explosions of electromagnetic radiation – astronomers worldwide have been combing the universe to uncover clues about how and why they form.  Nearly all FRBs identified have originated in deep space outside our Milky Way galaxy. That is until April 2020, when the first Galactic FRB, named FRB 20200428, was detected. This FRB was produced by a magnetar (SGR J1935+2154), a dense, city-sized neutron star with an incredibly powerful magnetic field.  This groundbreaking discovery led some to believe that FRBs identified at cosmological distances outside ...

Since the insulin pump started widespread use in the early 1980s, it’s become the option of choice for type 1 diabetes patients to manage their glucose levels in a way that doesn’t require testing their blood sugar and injecting insulin multiple times daily. But now, a first-of-its kind study is looking at the issue of patients “running out of real estate” due to pump sites becoming fibrotic, irritated and less effective at delivering insulin. The UW Medicine-led study was published July 14 in the journal Diabetes Care, a publication of the American Diabetes Association. “No ...

BOSTON - A new multi-center study led by doctors at Boston Medical Center and Columbia University found that having a genetic variant in the prealbumin gene alone is not sufficient for diagnosis of transthyretin amyloid cardiomyopathy in older Black patients. Published in the Journal of the American Heart Association, researchers discovered that a blood test that measures the transthyretin or prealbumin protein might also be helpful in diagnosing transthyretin amyloid cardiomyopathy and could be used to trigger more definitive imaging testing. Transthyretin amyloid cardiomyopathy (ATTR‐CM) is an underdiagnosed cause of congestive heart failure among patients 60+ years of age. ...

CAMBRIDGE, MA -- When breast cancer is diagnosed in the earliest stages, the survival rate is nearly 100 percent. However, for tumors detected in later stages, that rate drops to around 25 percent. In hopes of improving the overall survival rate for breast cancer patients, MIT researchers have designed a wearable ultrasound device that could allow people to detect tumors when they are still in early stages. In particular, it could be valuable for patients at high risk of developing breast cancer in between ...

(Memphis, Tenn.—July 28, 2023) The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children’s Research Hospital have added a new layer of understanding to explain why and how flu viruses change. The “survival of the accessible” model provides a complementary view to the more widely recognized “survival of the fittest” way of evolving. The work was published today in Science Advances.     Viruses undergo a rapid evolutionary flux due to constant genetic mutations. This rapid flux is why people get a flu shot ...

CORVALLIS, Ore. – Four decades of conservation spending totaling more than $9 billion in inflation-adjusted tax dollars has failed to improve stocks of wild salmon and steelhead in the Columbia River Basin, according to Oregon State University research. The study led by William Jaeger of the OSU College of Agricultural Sciences is based on an analysis of 50 years of data suggesting that while hatchery-reared salmon numbers have increased, there is no evidence of a net increase in wild, naturally spawning salmon and steelhead.  Findings were published today in PLOS One. Jaeger, a professor of applied economics, notes that ...

ITHACA, N.Y. - When considering ways to sustainably generate environmentally friendly products, bacteria might not immediately spring to mind. However, in recent years scientists have created microbe-semiconductor biohybrids that merge the biosynthetic power of living systems with the ability of semiconductors to harvest light. These microorganisms use solar energy to convert carbon dioxide into value-added chemical products, such as bioplastics and biofuels. But how that energy transport occurs in such a tiny, complex ...

Raman spectroscopy — a chemical analysis method that shines monochromatic light onto a sample and records the scattered light that emerges — has caused frustration among biomedical researchers for more than half a century. Due to the heat generated by the light, live proteins are nearly destroyed during the optical measurements, leading to diminishing and non-reproducible results. As of recently, however, those frustrations may now be a thing of the past. A group of researchers with the Institute for Quantum Sciences and Engineering at Texas A&M ...

URBANA, Ill. – Common beans are important food sources with high nutritional content. Bean seeds also contain phenolic compounds, which have antioxidant and anti-inflammatory properties that promote health. A study from the University of Illinois Urbana-Champaign and CIATEJ in Guadalajara, Mexico, explored the composition of seed coat extracts from black and pinto bean varieties unique to the Chiapas region of Southern Mexico. “These beans are preserved among Mayan communities and grown by indigenous farmers. They are heirlooms from past generations and are important because of their cultural significance and contribution to biodiversity,” explained ...

A gene that plays a key role in regulating how bodies change across the 24-hour day also influences memory formation, allowing mice to consolidate memories better during the day than at night. Researchers at Penn State tested the memory of mice during the day and at night, then identified genes whose activity fluctuated in a memory-related region of the brain in parallel with memory performance. Experiments showed that the gene, Period 1, which is known to be involved in the body’s circadian clock, is crucial for improved daytime memory performance. The research demonstrates a link between the circadian system and memory formation ...

Growth over the coming decade is projected to take off in three growth poles, East Asia, Eastern ...

To study play behaviors in animals, scientists must be able to authentically simulate play-conducive environments in the laboratory. Animals like rats are less inclined to play if they are anxious or restrained, and there is minimal data on the brain activity of rats that are free to play. After getting rats comfortable with a human playmate, tickling them under controlled conditions, then measuring the rats’ squeaks and brain activity, a research team reports on July 27 in the journal Neuron that a structure in rat brains called the periaqueductal gray is essential for play and laughter. “We know that vocalizations such as laughter are very ...

Scientists have pinpointed a genetic cause for virgin birth for the first time, and once switched on the ability is passed down through generations of females. For the first time, scientists have managed to induce virgin birth in an animal that usually reproduces sexually: the fruit fly Drosophila melanogaster. Once induced in this fruit fly, this ability is passed on through the generations: the offspring can reproduce either sexually if there are males around, or by virgin birth if there aren’t. For most animals, reproduction is sexual - it involves a female’s egg being fertilised by a male’s sperm. ...

Neurons are the cells that constitute neural circuits and use chemicals and electricity to receive and send messages that allow the body to do everything, including thinking, sensing, moving, and more. Neurons have a long fiber called an axon that sends information to the subsequent neurons. Information from axons is received by branch-like structures that fan out from the cell body, called dendrites. Dendritic refinement is an important part of early postnatal brain development during which dendrites are tailored to make specific connections with appropriate axons. In a recently published paper, researchers present evidence showing how a mechanism within the neurons of a rodent involving ...

Kyoto, Japan -- Having control over how a dish is cooked is always a good idea. Taking a hint from the kitchen, scientists appear to have discovered a way to produce a true structure of the rare but naturally-occurring anti-HIV compound Lancilactone C from start to finish. Its non-cytotoxicity in mammals could make this triterpenoid an ideal candidate for treating AIDS if its biological activity were clear -- and if only it were abundant in nature. Now, a research group at Kyoto University has succeeded in ...
