The study looked at 116 children ages 7 through 12 .
Twenty-one of the children with ASD spoke more than one language, and 35 of the typically developing children were multilingual.
The researchers tested the children’s executive function abilities and asked parents to fill out questionnaires assessing autism symptoms.

The fastest supercomputer in the world has officially launched at the Lawrence Livermore National Laboratory ( LNNL ) in California .
The supercomputer, called " El Capitan ," cost $600 million to build and will handle various sensitive and classified tasks including securing the U.S. stockpile of nuclear weapons.
Research will primarily be focused on national security, including material discovery, high-energy-density physics, nuclear data and weapon design.
El Capitan is powered by just over 11 million processing and graphics cores packed into 44,544 AMD MI300A accelerated processing units.

Hawaii is the rainbow capital of the world. Here's what that means

Hawaii ’s sunshine, short rain showers and clean air together create some of the planet's best conditions for viewing rainbows.
University of Hawaii professor calls the state the “rainbow capital of the world” Right now it's the winter rainy season in the islands, which means the odds of seeing a rainbow are even higher than usual.
Rainbows emerge so often in Hawaii they've become popular symbols of island life.
Scientists believe rainbows will continue to be plentiful in Hawaii , but in the coming decades , longer dry spells might lead to fewer rainbows on the arid, leeward sides of the islands.
Maui and the Big Island might be particularly affected.
“Rainbows are a cultural touchstone for us,” professor says.

Scientists discover mitochondria's role in shaping memory circuits

Mitochondrial dysfunction is a major contributor to neurological disorders such as Alzheimer's disease, autism, schizophrenia, and depression.
The research in mouse models examines the hippocampal CA2 region, a specialized area in the brain's memory center essential for social recognition memory.
The researchers deleted the MCU gene in CA2 neurons of genetically engineered mice.
This caused a disruption in plasticity at the outermost synapses, leading to problems with thinking and memory.

Life on Earth Depends on Networks of Ocean Bacteria

Prochlorococcus bacteria are likely the most abundant photosynthetic organism on the planet.
They create a significant portion—10 percent to 20 percent of the atmosphere’s oxygen.
Biologists once thought of these organisms as isolated wanderers, adrift in an unfathomable vastness.
But biologists now think bacteria have been making these structures all along unnoticed.
Researchers from the University of Córdoba , Spain , have discovered nanotubes in marine bacteria.
Scientists watched cells sprout from the tubes and then investigated what they carried.
Moving across these bridges from cell to cell were substances such as amino acids, the basic building blocks of proteins and enzymes and toxins.
Bacteria with streamlined genomes sometimes form interdependent communities with organisms that produce what they need and need what they produce.
Researchers have found that nanotubes can support cooperation among groups of bacteria.
This kind of cooperation is probably more common than people realize, says Conrad Mullineaux , a microbiologist.

Is the moon still geologically active? Evidence says it's possible

Scientists have found 266 "wrinkle ridges" on the lunar far side of the moon.
These ridges appear to have formed during the past 160 million years in volcanic plains on the far side.
The moon may still be geologically active, says planetary geologist Jaclyn Clark of the University of Maryland .
The findings were published on January 21 in The Planetary Science Journal .
If moonquakes are severe enough in some parts of the Moon , they could pose a hazard to human activity on the lunar surface.
Astronauts would have to avoid those areas in order to stay safe.

Radio signals, artificial light, and nitrogen dioxide emissions are Earthâs most detectable up to 12,000 light-years away.
The closer an alien civilization is to Earth , the more technosignatures it would detect, such as radio signals.

The Moon Might be Older Than We Previously Thought

Scientists have a collection of Moon rocks, which they can measure the age of.
The oldest rocks are all about 4.35 billion years old, which is roughly 200 million years after the birth of the solar system.
The Moon would have raised gigantic tides on the early Earth , which itself was mostly molten and spinning rapidly.
These tides took energy from the Earth ’s spin and transferred some to the Moon ’s orbit, slowly pushing the Moon away from Earth .
This motion continues today .
Very often in Earth and planetary sciences, geochemists and geophysicists end up with different and contradictory hypotheses. This happens partly because these fields use different kinds of measurements, but also because they speak very different scientific languages. Overcoming this language barrier is hard. Our study is an example of how sometimes bridging that linguistic and scientific divide can benefit researchers on both sides.
