Brain-imaging study reveals curiosity as it emerges

Science Daily - 09/07/2024
You look up into the clear blue sky and see something you can't quite identify. Is it a balloon? A plane? A UFO? You're curious, right? A research team has for the first time witnessed what is happening in the human brain when feelings of curiosity like this arise. The scientists revealed brain areas that appear to assess the degree of uncertainty in visually ambiguous situations, giving rise to subjective feelings of curiosity.

Stench of a gas giant? Nearby exoplanet reeks of rotten eggs, and that's a good thing

Science Daily - 09/07/2024
An exoplanet infamous for its deadly weather has been hiding another bizarre feature -- it reeks of rotten eggs, according to a new study of data from the James Webb Space Telescope.

Americans find hospital-at-home care appealing and safe, study suggests

Science Daily - 09/07/2024
The study found that most survey respondents felt they would recover faster if cared for at home, rather than in the hospital, and that they felt safe being treated at home.

Scientists discover how to improve vaccine responses to potentially deadly bacterium

Science Daily - 09/07/2024
Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.

Employees prefer human performance monitors over AI, study finds

Science Daily - 09/07/2024
Organizations using AI to monitor employees' behavior and productivity can expect them to complain more, be less productive and want to quit more -- unless the technology can be framed as supporting their development, research finds.

Study reveals environmental impact of artificial sweeteners

Science Daily - 09/07/2024
A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.

Novel compound offers improved defense against fentanyl overdoses

Science Daily - 09/07/2024
Researchers identified a novel compound aimed at improving the treatment of opioid overdoses.

Restored oyster sanctuaries host more marine life

Science Daily - 09/07/2024
Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.

Coral reefs: Battlegrounds for survival in a changing climate

Science Daily - 09/07/2024
Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs' smallest inhabitants.

New extremely fast carbon storage technology

Science Daily - 09/07/2024
A new way to store carbon captured from the atmosphere works much faster than current methods without the harmful chemical accelerants they require.

Combining popular diabetes drugs offers complementary heart and kidney benefits

Science Daily - 09/07/2024
New research shows combined use of sodium glucose co-transporter 2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP1-RAs) is likely to offer additional protection against heart and kidney disease in patients with diabetes.

Innovative, highly accurate AI model can estimate lung function just by using chest x-rays

Science Daily - 09/07/2024
An artificial intelligence (AI) model that can estimate with high accuracy a person's lung function just by using a chest radiograph has been successfully developed.

New bio-based tool quickly detects concerning coronavirus variants

Science Daily - 09/07/2024
Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.

Diamonds pose a quantum block to India’s research ambition

The Hindu:Science - 09/07/2024
India, despite being a formidable industry in cutting and polishing diamonds, has only just begun manufacturing diamonds

Scientists find proof pain-sensing cells are either male or female

The Hindu:Science - 09/07/2024
Unravelling the different mechanisms that drive pain-sensing will help us design sex-specific pain therapies

In an electric vehicle, what is regenerative braking? | Explained

The Hindu:Science - 09/07/2024
Regenerative braking is a system designed to convert the kinetic energy of the wheels to a form that can be stored and used for other purposes

Companies that mitigate climate change reduce their cost of capital

Science Daily - 08/07/2024
A recent study explored the relationship between corporate climate change mitigation actions and the cost of capital for 2,100 Japanese listed companies from 2017 to 2021. The findings reveal that companies that maintain lower carbon intensity and disclose more climate-related information can reduce their capital costs. Conversely, mere commitments to climate change without actionable measures do not significantly impact costs.

Hexagonal perovskite oxides: Electrolytes for next-generation protonic ceramic fuel cells

Science Daily - 08/07/2024
Researchers have identified hexagonal perovskite-related oxides as materials with exceptionally high proton conductivity and thermal stability. Their unique crystal structure and large number of oxygen vacancies enable full hydration and high proton diffusion, making these materials ideal candidates as electrolytes for next-generation protonic ceramic fuel cells that can operate at intermediate temperatures without degradation.
