Chicks prove vision and touch linked at birth

Study reveals that newly hatched chicks can instantly recognise objects with their vision, even if they've only ever experienced them by touch.

2024-04-03
(Press-News.org) Newly hatched chicks raised in darkness and allowed to touch either a smooth or bumpy cube for 24 hours instantly recognised the object with their vision upon first exposure to light.  

This suggests chicks can link touch and vision without any prior experience combining these senses, challenging the long-held belief that such integration requires learning.  

The discovery implies a pre-wired ability in the brain for cross-modal perception, potentially redefining our understanding of animal cognition and sensory processing. 

In a study published in Biology Letters, researchers at Queen Mary University of London have cracked a centuries-old philosophical question about sight and touch. Led by Dr Elisabetta Versace, the team used chicks to finally answer the question posed by William Molyneux in 1688: can someone born blind instantly recognize objects by sight after gaining vision? 

Molyneux proposed a scenario where a person blind from birth learns to distinguish a cube from a sphere by touch. Would they then be able to recognise these shapes visually upon gaining sight? Studying this question in humans is ethically challenging. However, Dr Versace and her team used chicks, which hatch with well-developed sensory systems. 

"Unlike humans and other mammals," explains Dr Versace, Senior Lecturer at the School of Biological and Behavioural Sciences, chicks hatch with developed sensory systems. This allowed us to raise them in darkness and expose them to either a smooth or bumpy object for the first 24 hours of their lives – their first ever tactile experience." 

Remarkably, when exposed to light for the first time, chicks that had touched a smooth object preferentially approached the visual representation of a smooth object, and vice versa. This suggests that chicks can inherently link touch with sight, even without any prior visual experience. 

"This finding contradicts traditional theories," says Dr Versace. "It suggests our brains are pre-wired to make connections between different senses, even before we have ever used them together." 

This breakthrough opens exciting new avenues in understanding how our brains process information across different senses. It could also lead to a deeper understanding of how our senses develop and interact with the world around us.

Researchers propose new step in tectonic squeeze that turns seafloor into mountains
2024-04-03
Scientists use tiny minerals called zircons as geologic timekeepers. Often no bigger than a grain of sand, these crystals record chemical signatures of the geological environment where they formed. In a new study led by scientists at The University of Texas at Austin, researchers used them to describe what could be an overlooked step in a fundamental tectonic process that raises seafloors into mountains.   In a study published in the journal Geology, the researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated ...

Double trouble: the risks of mixing alcohol and sports wagering
2024-04-02
It turns out that money isn’t the only thing sports gamblers are risking. According to a new study, bettors who wager on sporting events, esports, and daily fantasy sports are much more likely than other individuals to binge drink. The findings, compiled by a research team from UNLV and the University of New Mexico, were published this week in the journal JAMA Network Open. Over the course of three weeks in spring 2022, researchers surveyed more than 4,300 adults across the U.S. Nearly 3,300 self-reported past year alcohol use, while about 1,800 identified themselves as gamblers who had bet on sports in the past year. Researchers ...

Far-UVC light can virtually eliminate airborne virus in an occupied room

2024-04-02
NEW YORK, NY--Far-UVC light is a promising new technology for reducing airborne virus levels in occupied indoor spaces, but its effectiveness has not been evaluated in real-life scenarios.  A new study by Columbia researchers now shows that far-UVC light inactivated nearly all (>99%) of an airborne virus in an occupied work environment, showing that the technology can work as well in a real-life scenario as in the laboratory.  “The results show that far-UVC is highly effective at reducing airborne pathogens in an ordinary occupied room, and so it’s practical to use far-UVC light in indoor areas where people are going about their business,” says David ...

A new estimate of U.S. soil organic carbon to improve Earth system models

2024-04-02
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate change, in addition to being vital to soil health and agricultural productivity. Measuring soil carbon, however, is a painstaking, expensive process. Samples must be dug from the ground and sent to a lab for analysis, making upscaling measurements on a large spatial scale ...

First results from BREAD experiment demonstrate a new approach to searching for dark matter

2024-04-02
One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it’s no minor thing—currently, scientists think it makes up about 85% of all the mass in the universe. A new experiment by a collaboration led by the University of Chicago and Fermi National Accelerator Laboratory, known as the Broadband Reflector Experiment for Axion Detection or BREAD, has released its first results in the search for dark matter in a ...

Ultra-intense ultrashort lasers are powerful tools used in various fields like physics, national security, industry, and healthcare. They help researchers delve into strong-field laser physics, laser-driven radiation sources, particle acceleration, and more. “Peak power” measures the intensity of these lasers, like the Nova laser (Lawrence Livermore National Laboratory, California, USA) with 1.5 petawatts of peak power, the Shanghai Super-intense Ultrafast Laser Facility (SULF, China) with 10 petawatts, or the Extreme Light Infrastructure – Nuclear Physics (ELI-NP, Romania) with a peak ...

Combining food taxes and subsidies can lead to healthier grocery purchases for low-income households

Chapel Hill, NC, April 2, 2024 — A new study that models the combined effects of a sugar-based tax on beverages and targeted subsidies for minimally processed foods and drinks found that under these policies, low-income consumers would purchase less sugar-sweetened beverages and more fruits, vegetables, and healthier drinks, particularly in households without children.   Researchers at the University of North Carolina at Chapel Hill developed a model to simulate what would happen if national-level taxes on less-healthy, ...
