A breakthrough astrophysics code rapidly models stellar collisions
- ScienceDaily
- 21/4/23 22:28
A new breakthrough astrophysics code, named Octo-Tiger, simulates the evolution of self-gravitating and rotating systems of arbitrary geometry using adaptive mesh refinement and a new method to parallelize the code to achieve superior speeds. This new code to model stellar collisions is more expeditious than the established code used for numerical simulations.
Body's natural pain killers can be enhanced
- ScienceDaily
- 21/4/23 22:28
A study in cells and mice finds a opioid-receptor modifying compound works to relieve pain using the body's own pain-killers, with fewer side effects than opioids.
Flexible diet may help leaf-eating lemurs survive deforestation
- ScienceDaily
- 21/4/23 20:13
A new study sequencing the genome of four species of sifakas (Propithecus), a genus of lemurs found in Madagascar's forests, reveals that these animals' taste for leaves runs all the way to their genes, which are also more diverse than expected for an endangered species. But they can also thrive on fruit and flowers, which may be an advantage over being strictly leaves-only or fruit-only in the...
High school junior's consumer seismometer delivers low-cost earthquake early warning

- 21/4/23 19:02
A deep spatiotemporal neural network trained on more than 36,000 earthquakes offers a new way of quickly predicting ground shaking intensity once an earthquake is underway, researchers report.
Force transmission between cells orchestrates collective cellular motion
- ScienceDaily
- 21/4/23 19:02
How do the billions of cells communicate in order to perform tasks? The cells exert force on their environment through movement - and in doing so, they communicate. They work as a group in order to infiltrate their environment, perform wound healing and the like. They sense the stiffness or softness of their surroundings and this helps them connect and organize their collective effort. But when...
Synthetic gelatin-like material mimics lobster underbelly's stretch and strength
- ScienceDaily
- 21/4/23 19:02
Researchers fabricated a synthetic hydrogel that mimics the stretch and strength of a lobster's underbelly. The material could provide a blueprint for stretchy protective fabrics and artificial tissues.
Research shows pain relieving effects of CBD
- ScienceDaily
- 21/4/23 19:02
In an experimental pain study of CBD in humans, researchers conclude that CBD pain relief is driven by both pharmacological action and psychological placebo effects.
Newly discovered immune cell function vital to healing
- ScienceDaily
- 21/4/23 19:01
Cardiovascular disease, the most common cause of death, is the result of oxygen deprivation as blood perfusion to affected tissue is prevented. To halt the development of the disease and to promote healing, re-establishment of blood flow is crucial. Researchers have now discovered that one of the most common immune cells in the human body, macrophages, play an important role in re-establishing and...
Heartbeat can help detect signs of consciousness in patients after a coma
- ScienceDaily
- 21/4/23 19:01
A new study shows that heart brain interactions, measured using electroencephalography (EEG), provide a novel diagnostic method for patients with disorders of consciousness.
Muscle gene linked to type 2 diabetes
- ScienceDaily
- 21/4/23 19:01
People with type 2 diabetes tend to have poorer muscle function than others. Now a research team has discovered that in type 2 diabetes, a specific gene is of great importance for the ability of muscle stem cells to create new mature muscle cells.
First description of a new octopus species without using a scalpel
- ScienceDaily
- 21/4/23 19:01
A biologist brought a new octopus species to light from depths of more than 4,000 meters in the North Pacific Ocean. Researchers have now published the species description and named the animal 'Emperor dumbo' (Grimpoteuthis imperator). Just as unusual as the organism is the researchers' approach: in order to describe the new species, they did not dissect the rare creature, but instead used...
Travel paths of primates show how their minds work
- ScienceDaily
- 21/4/23 19:01
Using data from 164 wild primate populations, the global survey examines the mental abilities that primates, including ourselves, use to know where and when to travel in the most efficient way.
Fight or flight response may hinge on protein in skeletal muscular system
- ScienceDaily
- 21/4/23 19:01
Researchers say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful situations.
Climate change affects deep-sea corals and sponges differently
- ScienceDaily
- 21/4/23 19:01
Corals and sponges are important foundations in ocean ecosystems providing structure and habitats that shelter a high number of species like fish, crabs and other creatures, particularly in the seamounts and canyons of the deep sea. Researchers have discovered that when it comes to climate change not all deep-sea corals and sponges are affected the same and some could be threatened if average...
Defense mechanisms in aphids can become a double-edged sword, sharpened by the seasons
- ScienceDaily
- 21/4/23 19:01
Scientists examined the biological variations in pea aphids, insects that reproduce frequently enough to evolve before our eyes, by tracing the prevalence of their protective endosymbiont, Hamiltonella defensa, which the insects use to ward off parasitoid wasps.
Skeletal defects may be ameliorated after immobility in the womb
- ScienceDaily
- 21/4/23 19:01
Researchers have discovered that some skeletal defects associated with a lack of movement in the womb during early development may still be ameliorated after such periods of immobility if movement resumes. The discovery was made using chicken embryos, which develop similarly to their human equivalents and which can be easily viewed as development takes place - raising hopes that the finding may...
The largest assessment of global groundwater wells finds many are at risk of drying up
- ScienceDaily
- 21/4/23 19:01
'Jack and Jill went up the hill to fetch a pail of water.' It's a silly rhyme, but one that highlights a simple fact: Humans have long relied on wells -- such as the one visited by Jack and Jill -- for their primary drinking water supply.

Red Sea is no longer a baby ocean
- ScienceDaily
- 21/4/23 15:54
The Red Sea is a fascinating and still puzzling area of investigation for geoscientists. Controversial questions include its age and whether it represents a special case in ocean basin formation or if it has evolved similarly to other, larger ocean basins. Researchers have now published a new tectonic model that suggests that the Red Sea is not only a typical ocean, but more mature than thought...

- ScienceDaily
- 21/4/23 15:54
Researchers have investigated how philosophical approaches can be used to think in new ways about pain and its management. The researchers advocate not merely reducing chronic pain management to searching and treating underlying physical changes but instead adopting an approach that focuses on the person as a whole.

Bacteria and viruses infect our cells through sugars: Now researchers want to know how they do it
- ScienceDaily
- 21/4/23 15:54
Most infectious bacteria and viruses bind to sugars on the surface of our cells. Now researchers have created a library of tens of thousands of natural cells containing all the sugars found on the surface of our cells. The library may help us understand the role played by sugars and their receptors in the immune system and the brain, the researchers behind the study explain.
