New eclipsing binary millisecond pulsar discovered by FAST

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have discovered a new eclipsing binary millisecond pulsar in the globular cluster NGC 6341 (or M92). The newly found object received designation PSR J1717+4308A or M92A. The finding is detailed in a paper published February 24 on arXiv.org.

Milky Way's warp caused by galactic collision, Gaia suggests

Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with another, smaller, galaxy, which sends ripples through the galactic disc like a rock thrown into water.

Shedding new light on black hole ejections

Academics from the University of Cape Town (UCT) are part of a research group led by the University of Oxford's Department of Physics that has observed a black hole ejecting material at close to the speed of light out to some of the largest angular distances (separations) ever seen. These observations have allowed a deeper understanding of how black holes feed into their environment.

Globular cluster billowing in the galactic wind

The galactic magnetic field plays an important role in the evolution of the galaxy, but its small-scale behaviour is still poorly known. It is also unknown whether it permeates the halo of the galaxy or not. By using observations of pulsars in the halo globular cluster 47 Tuc, an international research team led by Federico Abbate from the Max Planck Institute for Radio Astronomy in Bonn, Germany who started this work at University of Milano Bicocca and INAF-Astronomical Observatory of Cagliari, could probe the galactic magnetic field at scales of a few light years for the first time. They discovered an unexpected strong magnetic field in the direction of the cluster. This magnetic field points perpendicularly to the galactic disk and could be explained by an interaction with the galactic wind. This is a magnetized outflow that extends from the galactic disk into the surrounding halo and its existence has never been proven before.

Milky Way galaxy 'reverse engineered'

New lithium batteries from used cell phones

Lithium-ion batteries are used around the world, and though over the last few years they have had some competition, such as sodium and magnesium, they continue to be indispensable due to their high density and capacity. The issue is this: this metal has major availability and concentration problems. Almost 85% of its reserves are located in what is known as the Lithium Triangle, a geographical area found on the borders of Argentina, Bolivia and Chile. In addition, it seems that demand will rocket over the next few decades because of the implementation of electric vehicles. Each car equals about 7,000 cell phone batteries, so reusing their different components has become an issue of utmost importance.

Artificial sweeteners combined with carbs may be more harmful than those sweeteners alone

The influence of artificial sweeteners on the brain and ultimately metabolism has been hotly debated in recent years. Some studies have found adverse effects on blood sugar and insulin levels, while others have not. In a study publishing March 3 in the journal Cell Metabolism, researchers say the discrepancies in these studies may be due to how the sweeteners are consumed—or, more specifically, what they are consumed with.

Boosting energy levels within damaged nerves may help them heal

When the spinal cord is injured, the damaged nerve fibers—called axons—are normally incapable of regrowth, leading to permanent loss of function. Considerable research has been done to find ways to promote the regeneration of axons following injury. Results of a study performed in mice and published in Cell Metabolism suggests that increasing energy supply within these injured spinal cord nerves could help promote axon regrowth and restore some motor functions. The study was a collaboration between the National Institutes of Health and the Indiana University School of Medicine in Indianapolis.

Fear of COVID-19 is more pervasive than infection

All over the world, thousands of people have now been infected with the coronavirus. China has seen the highest number of cases thus far, but the virus has also struck in Italy, France, the US, Canada, and Japan. Headlines such as "Coronavirus: how worried should we be?", and "Corona death toll rises" reflect people's growing fear of the virus. But is that fear justified? It's still difficult to answer that question in the short term, given that the disease is a new one. But there's nothing new about the rampant fear. The cause of this fear lies in various psychological heuristics (underlying principles that influence the choices people make).

On the path toward non-addictive painkillers

Opioid-containing painkillers are virtually indispensable in clinical practice and are typically used in postoperative patients and patients undergoing cancer treatment. In addition to having severe side effects, however, these drugs have also been associated with extensive misuse, particularly in the United States. Recent findings by a team of researchers from Charité - Universitätsmedizin Berlin represent a significant step towards the development of a new generation of painkillers. Published in Scientific Reports, their findings show that tissue acidity—or tissue pH—at the source of the pain (i.e. injury) is a crucial determinant in the development of new drugs. This is because the fine-tuning of an opioid molecule's acid dissociation constant (pKa) will determine its risk profile, including its addiction potential.

We can make predictions about relationships - but is this necessary?

New way to identify patients likely to return to hospital could reduce future readmissions

Recurrent, unplanned readmissions to the hospital—which happen when patients return shortly after discharge and are readmitted for the same or a related condition—are a challenge worldwide. Many researchers have examined how to predict them and how to understand the factors that contribute to them. A new study looked at how the risk of readmission progressed over multiple visits to emergency departments (EDs) in Israel by patients with chronic diseases. The study explored a way to identify distinct groups of patients who are more likely to be readmitted so medical professionals can intervene to prevent or reduce the possibility of future readmissions.

Study suggests guidelines to improve Youtube videos on chronic health care conditions

Many people with chronic health conditions search social media, including YouTube videos, to learn more about how to manage their diagnoses. But these videos differ in how well they communicate information and hold viewers' attention. A better understanding of how patients engage with medical information is important for improving the use of health care resources and the quality of care. A new study sought to understand how people engage with health information in YouTube videos on diabetes. In the study, researchers developed an approach to identify videos with differing levels of medical information and examined viewers' engagement with those videos.

Is intermittent fasting a quick fix?

One of the latest diet trends is intermittent fasting. There are two common approaches to fasting. One is to eat few calories on certain days and then eat normally the rest of the time. The other involves eating only during certain hours and skipping meals for the rest of each day. In this Mayo Clinic Minute, Dr. Donald Hensrud, director of the Mayo Clinic Healthy Living Program, explains the potential benefits and risks to intermittent fasting.

Interplay between states and federal government in implementing the ACA

The fierce national debate over health care reform includes deep divisions over the appropriate roles of the federal and state governments. For example, while Sen Bernie Sanders (I-VT) calls for expanding the federal Medicare program to cover all Americans, the Trump administration pushes for the states to have far greater authority. However, according to Michael Sparer, JD, Ph.D., chair of health policy and management at the Columbia Mailman School of Public Health, the Affordable Care Act (ACA) points towards a more effective inter-governmental partnership, one in which the states have significant policy and administrative discretion, bounded by strong national standards designed to limit unacceptable inequities.

Biology news

Study: Rapamycin has harmful effects when telomeres are short

In the past few decades, researchers discovered that the rate at which we age is strongly influenced by biochemical processes that, at least in animal models, can be controlled in the laboratory. Telomere shortening is one of these processes; another is the ability of cells to detect nutrients mediated by the mTOR protein. Researchers have been able to prolong life in many species by modifying either one of them. But what if they manipulate both?

Advances in computer modeling, protein development propel cellular engineering

Recent advances in bioengineering and computational modeling have given researchers the ability to examine complex biological processes with molecular-level detail.

Research: Evolution of life cycle of parasitic worm that takes over 'zombie ants'

It could be the plot of a B-horror movie: microscopic parasitic worms invade the brains of ants, and use mind control to make the "zombies ants" do their bidding.

A glitch in the Matrix: Using virtual reality to understand how fish predict the future

Scientists from the Friedrich group have developed a new virtual reality system that allows them to manipulate the sensory environment of adult zebrafish at will, while simultaneously analyzing neural activity. This approach can be used to explore how the brain processes complex sensory inputs and how it uses internal models of the world to control behaviors.

New Cas9 variant makes genome editing even more precise

CRISPR-Cas9 has revolutionized the field of genetics by its ability to cut DNA at defined target sites. Researchers are using the Cas9 enzyme to specifically switch off genes, or insert new DNA fragments into the genome. But no matter how specific the Cas9 enzyme is—sometimes it cuts where it shouldn't. Scientists at the Max Planck Unit for the Science of Pathogens in Berlin and the Faculty of Medicine of the Martin Luther University Halle-Wittenberg now report a Cas9 variant that increases the specificity of genome editing.

From crocodiles to krill, a warming world raises the 'costs' paid by developing embryos

Apart from mammals and birds, most animals develop as eggs exposed to the vagaries of the outside world. This development is energetically "costly." Going from a tiny egg to a fully functioning organism can deplete up to 60% of the energy reserves provided by a parent.

Study underscores importance of molecular highways for organ health

Turns out, even your cells hate traffic jams.

Anti-evolution drug could stop antibiotic resistance

The spread of antibiotic resistance is partly due to the ability of bacteria to pick up DNA from their surroundings. A new study, which started at the University of Groningen, showed that drugs blocking this ability (which is called 'competence') in the bacterium Streptococcus pneumoniae can indeed stop the spread of resistance in mice. As competence is blocked without affecting cell growth, it will be difficult for the bacteria to evolve resistance to the blockade. The study was published online by the journal Cell Host & Microbe on 3 March.

Reef-building coral exhibiting 'disaster traits' akin to the last major extinction event

A study published Tuesday in Scientific Reports shows that stony corals, which provide food and shelter for almost a quarter of all ocean species, are preparing for a major extinction event.

Simulations show fundamental interactions inside the cell

Actin filaments have several important functions inside cells. For one, they support the cell membrane by binding to it. However, scientists did not know exactly how the actin interacts with the membrane lipids. Simulations performed at the University of Groningen, supported by experiments, provide a molecular view on this very fundamental process. The results were published in the journal Proceedings of the National Academy of Sciences on 2 March.

Imaging technique reveals 3-D forces exerted by tiny cell clusters

A team of researchers has developed a new technique to map the three-dimensional forces that clusters of human cells exert on their surrounding environment. The method could potentially help scientists better understand how tissue forms, how wounds heal or how tumors spread.

Evolution: That famous 'march of progress' image is just wrong

Evolution explains how all living beings, including us, came to be. It would be easy to assume evolution works by continuously adding features to organisms, constantly increasing their complexity. Some fish evolved legs and walked onto the land. Some dinosaurs evolved wings and began to fly. Others evolved wombs and began to give birth to live young.

'Sustainable gardening' includes many eco-friendly practices

"Sustainable" is one of gardening's trendiest buzzwords, yet it carries a range of definitions. Just what does it mean in practical terms, and how important is it to the average gardener?

African grey parrots help each other in times of need

People readily help each other. We donate blood and food or help old people across the street. Among non-human animals this propensity to help is very rare.

Common bee virus causes bees to forage prematurely

Honey bee pollination contributes roughly $15 billion to the U.S. agricultural industry each year, but diseases like deformed wing virus (DWV) can devastate bee health.

Zombie caterpillar fungus may contain anti-cancer drug – but there are still questions to be answered

Spores released by parasitic fungi of the group cordyceps infect insect hosts, causing the fungus to grow inside them. Eventually this kills the host, but a bizarre twist is that before they die their behaviour is changed to assist the release of new fungal spores.

Dragonflies consume hundreds of thousands of insects in a small area

A study led by the University of Turku has found that small, fiercely predatory damselflies catch and eat hundreds of thousands of insects during a single summer—in an area surrounding just a single pond. In terms of weight, this equates to a total prey mass of just under a kilo. Dragonflies mostly catch different kinds of midges, but also large numbers of other insects.

A tangled web: Teasing out the effects of CBD on canine seizures

Cannabidiol, popularly known as CBD, gained mainstream fame for treating seizures with a strain of hemp called "Charlotte's Web." It was named for Charlotte Figi, a child with Dravet syndrome whose family was so desperate for an effective therapy, they moved to Colorado in search of an answer. Her seizures were successfully treated with cannabis that contained high concentrations of CBD (a non-psychoactive component of cannabis) and very low concentrations of THC (the psychoactive component of cannabis).

I.Coast burns 3 tonnes of pangolin scales

Ivory Coast officials on Tuesday burnt three tonnes of scales of the pangolin, the most trafficked mammal on Earth.

Does your cat have degenerative joint disease?

With an estimated 10-15% of adults over the age of 60 having some degree of osteoarthritis, otherwise known as degenerative joint disease (DJD), many people will be familiar with, or will know someone who suffers from, this painful and debilitating condition. What is not well recognised is that DJD, where the protective cartilage that cushions the end of the bones wears down over time, affects a high proportion of pet cats of all age groups, but particularly those 10 years of age and over. A study published today in the Journal of Feline Medicine and Surgery (JFMS) provides a screening checklist to help veterinarians and owners to identify cats experiencing DJD-associated pain.
