Saturn’s rings are raining down particles on its atmosphere
New research using the Hubble Space Telescope shows that Saturn's icy rings actually heat up its upper atmosphere......»»
Modified nano-sized cell particles found to boost cancer immunotherapy, reduce side effects
Immunotherapy is a type of cancer treatment that uses the body's own immune system to help fight cancer. This is by stimulating the immune response to recognize and attack cancer cells more effectively. The treatment involves using substances that bo.....»»

A remarkable photo taken by an astronaut aboard the ISS shows SpaceX’s Polaris Dawn Crew Dragon capsule entering Earth’s atmosphere at high speed on Sunday......»»
So what are we to make of the highly ambitious, private Polaris spaceflight?
They flew high, they walked in space, and finally early on Sunday, they landed. Enlarge / Crew Dragon enters Earth's atmosphere on Sunday morning as recovery boats await. (credit: SpaceX) A white spacecraft, lightly toas.....»»
Antarctic research finds exceptional warm air intrusions and omnipresent aerosol layers in the stratosphere
Extremely clean air on the ground, warm air intrusions and sulfate aerosol at high altitudes—a Leipzig research project has gained new insights into clouds in Antarctica. From January to December 2023, the vertical distribution of aerosol particles.....»»
Exploring ternary metal sulfides as electrocatalysts for carbon dioxide reduction reactions
One of the most promising avenues for actively reducing CO2 levels in the atmosphere is recycling it into valuable chemicals via electrocatalytic CO2 reduction reactions. With a suitable electrocatalyst, this can be achieved under mild conditions and.....»»
Researchers identify novel approach to minimize nitrogen loss in crops
While agriculture producers apply nitrogen fertilizer to supply nutrients to their crops, they can't always keep those nutrients in the soil for maximum efficiency, often losing them into the atmosphere or water supply as nitrates and nitrous oxide......»»
Microbe dietary preferences found to influence effectiveness of carbon sequestration in deep ocean
The movement of carbon dioxide (CO2) from the surface of the ocean, where it is in active contact with the atmosphere, to the deep ocean, where it can be sequestered away for decades, centuries, or longer, depends on a number of seemingly small proce.....»»
NASA"s EZIE mission set for 2025 launch
In 2025, NASA will launch its first mission to image the magnetic fingerprint of intense electrical currents that flow high in our atmosphere when auroras shimmer above Earth's poles......»»
Pollution of the potent warming gas methane soars and people are mostly to blame
The amount and proportion of the powerful heat-trapping gas methane that humans spew into the atmosphere is rising, helping to turbocharge climate change, a new study finds......»»
First publication of J.R.R. Tolkien"s collected poems offers new insights into author"s personality
If you have read The Lord of the Rings, there is a good chance that you skipped over one or more of the 75 songs and poems in J.R.R. Tolkien's fantasy epic. Yet long before he was the "father of modern fantasy", Tolkien's great ambition was to be a p.....»»
Study finds tire abrasion particles threaten fresh water habitats
A research team led by Prof. Dr. Markus Pfenninger from the Senckenberg Biodiversity and Climate Research Center Frankfurt (SBiK-F) has investigated the effects of tire-abrasion particles on freshwater ecosystems......»»
Unprecedented heat wave on the Tibetan plateau: Study highlights land-atmosphere interactions
Heat waves are generally thought to occur in hot, lowland regions—but what happens when extreme heat strikes the frigid, high-altitude Tibetan Plateau? Is the definition of a heat wave the same at 5,000 meters above sea level as it is in the plains.....»»
New dense sub-Saturn exoplanet discovered
Using the Transiting Exoplanet Survey Satellite (TESS), astronomers from the Physical Research Laboratory (PRL) in Ahmedabad, India and elsewhere, have detected a new sub-Saturn exoplanet with a relatively high density. The finding was reported in a.....»»
Researchers find live fungi, bacteria and viruses high in the Earth"s atmosphere
A team of climate, health and atmospheric specialists in Spain and Japan has found abundant live fungi, bacteria and viruses high in the Earth's atmosphere. In their study published in the Proceedings of the National Academy of Sciences, the group co.....»»
Fluctuating hydrodynamics theory could describe chaotic many-body systems, study suggests
Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics?.....»»
The case for adding iron to the ocean for carbon dioxide removal
While the urgent reduction of carbon dioxide (CO2) and other greenhouse gas emissions is needed as the primary activity to curb climate change, there is broad agreement for the need to remove CO2 already in the atmosphere. Given its outsized role in.....»»
New mass spectrometry technology could transform tiny sample analysis
Mass spectrometry is a powerful technique that allows scientists to break down and identify the building blocks of just about anything by measuring the mass of the tiny particles of which something is comprised. It has a major limitation, however—a.....»»
Greenpeace sounds alarm on microplastics ingested by Hong Kong wildlife
Microplastic particles turned up in the vast majority of waste samples taken from Hong Kong wildlife in a Greenpeace study, the group said Monday, suggesting that animals still ingest plastics even if they are not feeding in urban areas......»»
Old satellite to burn up over Pacific in "targeted" re-entry first
After 24 years diligently studying Earth's magnetic field, a satellite will mostly burn up over the Pacific Ocean on Sunday during a "targeted" re-entry into the atmosphere, in a first for the European Space Agency as it seeks to reduce space debris......»»
Physicists capture images of atoms flowing along a boundary without resistance despite obstacles in their path
Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls......»»
