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

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.
A creature of mystery: New Zealand’s love-hate relationship with eels
Native species have been revered, feared, hunted and tamed. Now experts hope revulsion can give way to fascinationFor many years, the top-rated attraction in the Tasman district of New Zealand was a cafe famed for its rural setting, seafood chowder – and tame eels.For a few dollars you could buy a pottle of mince and a wooden stick to take down to the stream, where a blue-black mass was shining,...
US and Iranian researchers collaborate on Lake Urmia restoration
In a rare exchange, scientists and water resources engineers from Iran and Utah are collaborating on a bold scientific study to restore one of the world's largest saline lakes.
‘No data’ linking Covid vaccines to menstrual changes, US experts say
Some have reported changes amid vaccine rollout but experts say ‘one unusual period is no cause for alarm’Experts are trying to assuage concerns and combat misinformation about how the Covid-19 vaccines may affect menstrual cycles and fertility, after anecdotal reports that some people experienced earlier, later, heavier or more painful periods following the jab.“So far, there’s no data...
Biden’s Climate Summit Made Progress. But We Won’t Reach Net Zero by 2050 Without Those Who Weren’t Invited
The United States convened 40 heads of state in a virtual climate summit this week, with the goal of eliciting commitments from attendees for radical reductions in carbon emissions.
The U.S. pledged 50% reduction below 2005 levels by 2030, and others announced their own new targets — with the overall goal of putting the planet on track to carbon neutrality by 2050, the minimum needed to...
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...
Flexible diet may help leaf-eating lemurs resist deforestation
Fruits and veggies are good for you and if you are a lemur, they may even help mitigate the effects of habitat loss.
From corals to crops: How life protects the plans for its cellular power stations
An international team of researchers led by the University of Bergen has uncovered how organisms from crops to corals may avoid deadly DNA damage during evolution.
High school junior's consumer seismometer delivers low-cost earthquake early warning
A Southern California high school junior has built a low-cost seismometer device that delivers earthquake early warnings for homes and businesses. Costing less than $100 for her to make today, the seismometer could someday be a regular household safety device akin to a smart smoke detector, says its inventor Vivien He.
New alloy can directly reduce the weight of heat removal systems by a third
The new alloys created by NUST MISIS scientists in cooperation with LG Electronics will help reduce the weight of radiators and heat removal systems in electric vehicles and consumer electronics by one third. The research results are published in the Journal of Magnesium and Alloys.
Response options should be at the center of climate risk assessment and management
A team of researchers from the Africa Climate and Development Initiative (ACDI) led a global team of 21 climate risk scholars to better understand and inform decision making around climate change risks in Africa and globally by examining how the drivers of risk interact.
Climate change affects deep-sea corals and sponges differently
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 at the University of New Hampshire have discovered that when it comes to climate change not all deep-sea corals and sponges are affected the same and some...
Fiber optic cable monitors microseismicity in Antarctica
At the Seismological Society of America's 2021 Annual Meeting, researchers shared how they are using fiber optic cable to detect the small earthquakes that occur in ice in Antarctica.
Seismicity on Mars full of surprises, in first continuous year of data
The SEIS seismometer package from the Mars InSight lander has collected its first continuous Martian year of data, revealing some surprises among the more than 500 marsquakes detected so far.
DeepShake uses machine learning to rapidly estimate earthquake shaking intensity
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 at the Seismological Society of America (SSA)'s 2021 Annual Meeting.
