Path to net-zero carbon capture and storage may lead to ocean
- ScienceDaily
- 23/3/31 19:15
Engineering researchers have developed a novel way to capture carbon dioxide from the air and store it in the 'infinite sink' of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e.,...

Mathematical model provides bolt of understanding for lightning-produced X-rays
- ScienceDaily
- 23/3/31 19:15
In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons -- the same type used for medical imaging. Researchers could recreate this phenomenon in the lab, but they could not fully explain how and why lightning produced X-rays. Now, two decades later, a team has discovered a new physical mechanism explaining naturally occurring X-rays associated...
A tighter core stabilizes SARS-CoV-2 spike protein in new emergent variants
- ScienceDaily
- 23/3/31 19:14
New research reveals that mutations in the stem of the SARS-CoV-2 spike protein led to the virus becoming progressively tighter over time, which may have improved the virus's ability to transmit through nasal droplets and infect host cells once in the body.
Ants took over the world by following flowering plants out of prehistoric forests
- ScienceDaily
- 23/3/31 18:06
Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the...
AI algorithm unblurs the cosmos
- ScienceDaily
- 23/3/31 18:06
Researchers adapted a well-known computer-vision algorithm used for sharpening photos and, for the first time, applied it to astronomical images from ground-based telescopes. While astrophysicists already use technologies to remove blur, the adapted AI-driven algorithm works faster and produces more realistic images than current technologies. The resulting images are blur-free and truer to life.
Microrobot technology: Externally connecting in vivo neural networks
- ScienceDaily
- 23/3/31 18:06
Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network research and the verification and analysis of cell therapy products.
Researchers discover birds with neurotoxin-laden feathers
- ScienceDaily
- 23/3/31 18:06
An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.

Form is (mal)function: Protein's shape lets bacteria disarm it
- ScienceDaily
- 23/3/30 23:22
Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system.
Fluid flow in the brain can be manipulated by sensory stimulation
- ScienceDaily
- 23/3/30 23:21
Researchers report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. The study demonstrates that manipulating blood flow in the brain with visual stimulation induces complementary fluid flow. The findings could impact treatment for conditions like Alzheimer's disease, which have been associated with declines in cerebrospinal fluid flow.
New, exhaustive study probes hidden history of horses in the American West
- ScienceDaily
- 23/3/30 23:21
Indigenous peoples as far north as Wyoming and Idaho may have begun to care for horses by the first half of the 17th Century, according to a new study by researchers from 15 countries and multiple Native American groups.
Scientists analyze sounds emitted by plants
- ScienceDaily
- 23/3/30 19:35
Researchers have recorded and analyzed sounds distinctly emitted by plants. The click-like sounds, similar to the popping of popcorn, are emitted at a volume similar to human speech, but at high frequencies, beyond the hearing range of the human ear.
Surprise finding shows that neutrophils can be key antitumor weapons
- ScienceDaily
- 23/3/30 18:28
White blood cells called neutrophils have an unappreciated role in eradicating solid tumors, according to a surprise discovery.
WPI-led team uncovers new details of SARS-COV-2 structure
- ScienceDaily
- 23/3/30 18:27
Researchers used computational modeling to reveal finer details surrounding the outer shell of the COVID-19 virus. The work expands the scientific community's understanding of SARS-COV-2, and could lead to more refined antiviral therapies and better vaccines.
'Taffy galaxies' collide, leave behind bridge of star-forming material
- ScienceDaily
- 23/3/30 16:24
The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF's NOIRLab, captured a dazzling image of UGC 12914 and UGC 12915, which are nicknamed the Taffy Galaxies. Their twisted shape is the result of a head-on collision that occurred about 25 million years prior to their appearance in the image. A bridge of highly turbulent gas devoid of significant star...

- ScienceDaily
- 23/3/30 16:22
A new analysis shows that, compared to similarly high-income European countries, the United States continues to have substantially higher death rates at all but the oldest ages, resulting in more 'excess deaths,' and this gap widened during the COVID-19 pandemic.

Earth prefers to serve life in XXS and XXL sizes
- ScienceDaily
- 23/3/30 16:22
Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
