Study reveals why AI models that analyze medical images can be biased

Science Daily - 28/06/2024
Researchers have found that artificial intelligence models that are most accurate at predicting race and gender from X-ray images also show the biggest 'fairness gaps' -- that is, discrepancies in their ability to accurately diagnose images of people of different races or genders.

Climate change to shift tropical rains northward

Science Daily - 28/06/2024
Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.

Depictions of depression are often misleading

Science Daily - 28/06/2024
A recent study shows that people are commonly given misleading information about depression. According to the researchers, the inaccurate information makes it harder for people to understand the causes of their distress.

Researchers develop fastest possible flow algorithm

Science Daily - 28/06/2024
Computer scientists have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum transport costs for any type of network. It thus solves a key question in theoretical computer science. The superfast algorithm also lays the foundation for efficiently computing very large and dynamically changing networks in the future.

A dog's puppyhood can cause 'puppy blues' reminiscent of baby blues

Science Daily - 28/06/2024
Bringing a puppy home is usually a happy event, but sometimes the life change that comes with it can provoke significant negative emotions. Researchers found that almost half of dog owners experience anxiety, weariness or frustration during their dog's puppyhood stage.

Chemo drug may cause significant hearing loss in longtime cancer survivors

Science Daily - 28/06/2024
A new study tracked a cohort of testicular cancer survivors who received cisplatin-based chemotherapy for an average of 14 years, revealing that 78% experience significant difficulties in everyday listening situations, negatively impacting their quality of life.

Crohn's discovery could lead to better treatments for devastating condition

Science Daily - 28/06/2024
The new research suggests answers to why children with relapsing Crohn's endure repeated bouts even after appearing to recover. Doctors may be able to target this underlying cause to better treat Crohn's -- or even cure it.

Creating supranormal hearing in mice

Science Daily - 28/06/2024
A new study has produced supranormal hearing in mice, while also supporting a hypothesis on the cause of hidden hearing loss in people.

Too many missing satellite galaxies found

Science Daily - 28/06/2024
Bringing us one step closer to solving the 'missing satellites problem,' researchers have discovered two new satellite galaxies.

Breakthrough research makes cancer-fighting viral agent more effective

Science Daily - 28/06/2024
Researchers have made a significant breakthrough by discovering that the drug 4-OI can enhance the effectiveness of a cancer-fighting viral agent. This may lead to treatment of cancers that are otherwise resistant to therapies.

New class of Mars quakes reveals daily meteorite strikes

Science Daily - 28/06/2024
An international team of researchers combine orbital imagery with seismological data from NASA's Mars InSight lander to derive a new impact rate for meteorite strikes on Mars. Seismology also offers a new tool for determining the density of Mars' craters and the age of different regions of a planet.

New model could help provide expectant mothers a clearer path to safe fish consumption

Science Daily - 28/06/2024
Research creates a framework to better balance the nutritional benefit of fish consumption with the risk of mercury exposure to the developing brain.

Visual explanations of machine learning models to estimate charge states in quantum dots

Science Daily - 28/06/2024
To form qubit states in semiconductor materials, it requires tuning for numerous parameters. But as the number of qubits increases, the amount of parameters also increases, thereby complicating this process. Now, researchers have automated this process, overcoming a significant barrier to realizing quantum computers.

The future of metals research with artificial intelligence

Science Daily - 28/06/2024
A research team has developed an optimal artificial intelligence model to predict the yield strength of various metals, effectively addressing traditional cost and time limitations.

Adults conceived by donors left behind by fertility industry

Science Daily - 28/06/2024
Children conceived by using egg or sperm donors have the same well-being outcomes as non-donor conceived people.

Analysis suggests 2021 Texas abortion ban resulted in increase in infant deaths in state in year after law went into effect

Science Daily - 28/06/2024
Researchers use statistical modeling to estimate infant deaths expected if one of the country's most stringent state abortion laws had not been enacted. The study estimates that infant deaths in Texas increased more than expected in the year following the state's 2021 ban on abortion in early pregnancy, especially among infants with congenital anomalies.

A heart of stone: Study defines the process of and defenses against cardiac valve calcification

Science Daily - 28/06/2024
The human body has sophisticated defenses against the deposition of calcium minerals that stiffen heart tissues, researchers at the University of Illinois Urbana-Champaign and collaborators at UCLA Health and the University of Texas at Austin found in a new study that provides the first detailed, step-by-step documentation of how calcification progresses.

Materials research revolutionized by a small change

Science Daily - 28/06/2024
Scientists develop the next generation of highly efficient memory materials with atom-level control.

Synthetic fuels and chemicals from CO2: Ten experiments in parallel

Science Daily - 28/06/2024
Why do just one experiment at a time when you can do ten? Researchers have developed an automated system, which allows them to research catalysts, electrodes, and reaction conditions for CO2 electrolysis up to ten times faster. The system is complemented by an open-source software for data analysis.

Light-controlled artificial maple seeds could monitor the environment even in hard-to-reach locations

Science Daily - 28/06/2024
Researchers have developed a tiny robot replicating the aerial dance of falling maple seeds. In the future, this robot could be used for real-time environmental monitoring or delivery of small samples even in inaccessible terrain such as deserts, mountains or cliffs, or the open sea. This technology could be a game changer for fields such as search-and-rescue, endangered species studies, or infrastructure monitoring.
