NASA and NOAA rank 2024 ozone hole as 7th-smallest since recovery began
Healing continues in the atmosphere over the Antarctic: a hole that opens annually in the ozone layer over Earth's southern pole was relatively small in 2024 compared to other years. Scientists with NASA and the National Oceanic and Atmospheric Admin.....»»
This ancient tadpole fossil is the oldest ever discovered
Scientists have discovered the oldest-known fossil of a giant tadpole that wriggled around over 160 million years ago......»»
Scientists describe how mycobacteria evade the effects of antibiotics
One of the main challenges of contemporary medicine is posed by the resistance of pathogens to antibiotics. An important step in countering it has now been made by researchers from IOCB Prague, in collaboration with colleagues from the Institute of M.....»»
AI training method can drastically shorten time for calculations in quantum mechanics
The close relationship between AI and highly complicated scientific computing can be seen in the fact that both the 2024 Nobel Prizes in Physics and Chemistry were awarded to scientists for devising AI for their respective fields of study. KAIST rese.....»»
Study models dinoflagellate light in breaking waves
A new study led by Scripps Institution of Oceanography demonstrates, for the first time, how scientists can use computer simulations to quantify the light emitted by dinoflagellates when they flash in breaking waves and create stunning displays of bi.....»»
Changing climate could increase mobility of toxic metals in soils, experimental study shows
The changes scientists expect in the climate could cause toxic metals naturally occurring in soils to become more mobile, destabilize ecosystems and increasingly enter the human food chain via agriculture. Such scenarios are particularly likely to oc.....»»
Compact in-incubator imaging device allows real-time remote monitoring of cell growth
Unlike most cells in the human body, stem cells have the unique ability to divide indefinitely. This property makes them especially appealing to scientists exploring ways to extend human lifespans or develop new methods for repairing damaged tissues......»»
A new genetic web tool can help restore climate-resilient marine ecosystems
In the face of increased human pressures and climate change, a team of Australian scientists led by Dr. Georgina Wood at Flinders University has launched a new online tool to assist marine managers and restoration experts to bolster the resilience of.....»»
Scientists identify gene that regulates pod width in snap beans
iSnap bean (Phaseolus vulgaris L.) is a significant vegetable crop globally, with its immature pods harvested as the edible part. Pod dimensions–length, width, and thickness–affect the size and ease of harvest. This is particularly for manual plu.....»»
Modified metal-organic framework can capture benzene in the atmosphere to tackle a major health risk
Scientists have developed a new material capable of capturing the harmful chemical benzene from the polluted air, offering a potential solution for tackling a major health and environmental risk......»»
Mars may have been habitable much more recently than thought
Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for scientists investigating wh.....»»
New image recognition technique for counting particles provides diffusion information
A team of scientists have invented a new technique to determine the dynamics of microscopic interacting particles by using image recognition to count the number of particles in an imaginary box. By changing the size of the observation box, such count.....»»
Scientists provide direct evidence of breakdown of spin statistics in ion-atom charge exchange collisions
Since the first X-ray image of a comet was reported using an X-ray telescope in 1996, the investigation of charge exchange in collisions between highly charged ions and atoms or molecules has emerged as a hot research topic......»»
Scientists uncover key mechanism in pathogen defense, paving way for new antimicrobial strategies
Researchers have made a significant breakthrough in understanding how certain pathogens defend themselves against the host's immune system......»»
eROSITA survey unveils asymmetries in temperature and shape of our Local Hot Bubble
Our solar system dwells in a low-density environment called the Local Hot Bubble (LHB), filled by a tenuous, million-degree hot gas emitting dominantly in soft X-rays. A team led by scientists at the Max Planck Institute for Extraterrestrial Physics.....»»
Pesticides: Farming chemicals make insects sick at non-deadly doses—especially in hot weather
The various regulatory systems for approving pesticides in operation around the world are crude and flawed. This has long been clear to scientists and it is deeply worrying, as this regulation is supposed to protect people and the environment from ha.....»»
Scientists demonstrate precise control over artificial microswimmers using electric fields
In a new study in Physical Review Letters, scientists have demonstrated a method to control artificial microswimmers using electric fields and fluid flow. These microscopic droplets could pave the way for targeted drug delivery and microrobotics......»»
Scientists create a molecular switch that can control cell division on demand outside of a living system
