Children's visual experience may hold key to better computer vision training

Science Daily - 01/06/2024
A novel, human-inspired approach to training artificial intelligence (AI) systems to identify objects and navigate their surroundings could set the stage for the development of more advanced AI systems to explore extreme environments or distant worlds, according to new research.

The Hindu:Science - 31/05/2024
As per IMD’s Thursday briefing, maximum temperatures in northwest and central India are predicted to fall gradually by 2-4 degrees C in the next five days.

Infants hear significantly more speech than music at home

Science Daily - 31/05/2024
A new study has compared the amount of music and speech that children hear in infancy. Results showed that infants hear more spoken language than music, with the gap widening as the babies get older.

Trout in mine-polluted rivers are genetically 'isolated'

Science Daily - 31/05/2024
Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.

New coral disease forecasting system

Science Daily - 31/05/2024
Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.

Glimpses of a volcanic world: New telescope images of Jupiter's moon Io rival those from spacecraft

Science Daily - 31/05/2024
Combining a new imaging instrument with the powerful adaptive optics capabilities of the Large Binocular Telescope, astronomers have captured a volcanic event on Jupiter's moon Io at a resolution never before achieved with Earth-based observations.

Novel mobile air monitoring technology yields greater insight into post-disaster pollution levels

Science Daily - 31/05/2024
A team has found that high resolution mass spectrometry could be a valuable tool for identifying and assessing air-borne contaminants produced by natural and human-made disasters.

Tiny worm helps uncover long-lasting prenatal effects from amphetamines

Science Daily - 31/05/2024
During pregnancy, the effects of therapeutical doses of amphetamine have been investigated on birth outcomes in humans. However, a thorough investigation of the mechanisms underlying the long-term effects of embryonal exposure to addictive doses of amphetamine remains largely unexplored. Using a tiny worm, researchers have revealed the underlying mechanisms of embryonal exposure to methamphetamine (Meth) and amphetamines, a psychostimulant used to treat a variety of brain dysfunctions.

'Ugly' fossil places extinct saber-toothed cat on Texas coast

Science Daily - 31/05/2024
This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.

In the brain at rest, neurons rehearse future experience

Science Daily - 31/05/2024
New research sheds light on how individual neurons in the hippocampus of rats stabilize and tune spatial representations during periods of rest following the animals' first time running a maze, offering first proof of neuroplasticity during sleep.

Light enables the generation of non-canonical amino acids

Science Daily - 31/05/2024
Researchers are building out the repertoire of chemical reactions, using light. They report a method using photobiocatalysis to produce non-canonical (not naturally occurring) amino acids that are valuable building blocks of peptide therapeutics, bioactive natural products and novel functional proteins.

Scientists develop most sensitive way to observe single molecules

Science Daily - 31/05/2024
A technical achievement marks a significant advance in the burgeoning field of observing individual molecules without the aid of fluorescent labels. While these labels are useful in many applications, they alter molecules in ways that can obscure how they naturally interact with one another. The new label-free method makes the molecules so easy to detect, it is almost as if they had labels.

How does 'not' affect what we understand? Scientists find negation mitigates our interpretation of phrases

Science Daily - 31/05/2024
When we're told 'This coffee is hot' upon being served a familiar caffeinated beverage at our local diner or cafe, the message is clear. But what about when we're told 'This coffee is not hot'? Does that mean we think it's cold? Or room temperature? Or just warm? A team of scientists has now identified how our brains work to process phrases that include negation (i.e., 'not'), revealing that it mitigates rather than inverts meaning -- in other words, in our minds, negation merely reduces the temperature of our coffee and does not make it 'cold.'

Gene variants foretell the biology of future breast cancers

Science Daily - 31/05/2024
In a finding that vastly expands the understanding of tumor evolution, researchers discover genetic biomarkers that can predict the breast cancer subtype a patient is likely to develop.

Medium and mighty: Intermediate-mass black holes can survive in globular clusters

Science Daily - 31/05/2024
New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars. The first ever star-by-star massive cluster-formation simulations revealed that sufficiently dense molecular clouds, the 'birthing nests' of star clusters, can give birth to very massive stars that evolve into intermediate-mass black holes.

People are altering decomposition rates in waterways

Science Daily - 31/05/2024
Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.

Historic iceberg surges offer insights on modern climate change

Science Daily - 31/05/2024
A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.

Scientists invent 'living bioelectronics' that can sense and heal skin

Science Daily - 31/05/2024
Reaserchers have created a prototype for what they call 'living bioelectronics': a combination of living cells, gel, and electronics that can integrate with living tissue. Tests in mice found that the devices could continuously monitor and improve psoriasis-like symptoms, without irritating skin.

Scientists develop visual tool to help people group foods based on their levels of processing

Science Daily - 31/05/2024
Scientists studying ultra-processed foods have created a new tool for assessing the rewarding and reinforcing properties of foods that make up 58 percent of calories consumed in the United States. The foods have been linked to a wide range of negative health outcomes.
