Rare 3D fossils show that some early trees had forms unlike any you've ever seen

Science Daily - 02/02/2024
In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.

Science and research should move out of elite institutions: URSC Director

URSC is responsible for designing, developing and operationalising space projects, like Chandrayaan-3 and Aditya L-1 missions

How leafcutter ants cultivate a fungal garden to degrade plants and provide insights into future biofuels

Science Daily - 02/02/2024
Scientists developed a new method to map exactly how a fungus works with leafcutter ants in a complex microbial community to degrade plant material at the molecular level. The team's insights are important for biofuels development.

Disrupted cellular function behind type 2 diabetes in obesity

Science Daily - 02/02/2024
Disrupted function of 'cleaning cells' in the body may help to explain why some people with obesity develop type 2 diabetes, while others do not. A study describes this newly discovered mechanism.

A clutch stretch goes a long way

Science Daily - 02/02/2024
New results reveal a new mode of force transmission in which dynamic molecular stretching bridges the extracellular matrix and flowing F-actin moving at different speeds. This discovery underscores the necessity of molecular elasticity and random coupling for sufficiently transmitting force. The findings also call for revising the role of molecular unfolding.

Zebrafish navigate to find their comfortable temperature

Science Daily - 02/02/2024
Zebrafish are smaller than your little finger, with a brain no more than half the size of a pinhead. Yet these animals possess an efficient navigation system that enables them to find their way back to spots in the water where the temperature suits them.

Researchers use the eye as a window to study liver health

Science Daily - 02/02/2024
Researchers have developed a method to study liver function and disease without requiring invasive procedures. After transplanting liver cells into the eye of mice, the cornea can be used as a window into the body to monitor liver health over time.

Researchers 3D-print functional human brain tissue

Science Daily - 02/02/2024
It's an achievement with important implications for scientists studying the brain and working on treatments for a broad range of neurological and neurodevelopmental disorders, such as Alzheimer's and Parkinson's disease.

AI learns through the eyes and ears of a child

Science Daily - 02/02/2024
Researchers have been skeptical that recent AI advances can tell us much about human learning and development. To address this, a team training an AI model, not on massive data, but on the input that a single child receives. Their findings showed that the model could learn a substantial number of words and concepts using limited slices of what the child experienced.

Clown anemonefish seem to be counting bars and laying down the law

Science Daily - 02/02/2024
We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research suggests that our marine cousins may be more cognizant than we credit them for. Fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies.

The arrangement of bacteria in biofilms affects their sensitivity to antibiotics

Science Daily - 02/02/2024
Many bacteria form an antibiotic-resistant slime. Research detailing that slime's structure could help lead to new treatments.

Human cells building 'molecular highways' captured for first time

Science Daily - 02/02/2024
Researchers have captured the world's first high-resolution images of the earliest moments of microtubules forming inside human cells. The findings lay the foundations for potential breakthroughs in treating many different types of diseases ranging from cancer to neurodevelopmental disorders.

Diabetes and liver cancer: Study suggests new screening guidelines

Science Daily - 02/02/2024
A new study identifies an easily measured biophysical property that can identify Type 2 diabetics at increased risk for liver cancer who don't meet current screening guidelines.

Psychological care delivered over the phone is an effective way to combat loneliness and depression, according to a major new study

Science Daily - 02/02/2024
The results of the study, a major clinical trial carried out during the Covid pandemic, showed rapid and enduring improvements in mental health and quality of life when older people received weekly phone calls over eight weeks from a specially trained coach who encouraged them to maintain their social connections and to remain active.

Small RNAs take on the big task of helping skin wounds heal better and faster with minimal scarring

Science Daily - 01/02/2024
New findings report that a class of small RNAs (microRNAs), microRNA-29, can restore normal skin structure rather than producing a wound closure by a connective tissue (scar). Any improvement of normal skin repair would benefit many patients affected by large-area or deep wounds prone to dysfunctional scarring.

Why women are at greater risk of autoimmune disease

Science Daily - 01/02/2024
Research throws light on the mystery of why women are much more prone to autoimmune disorders: A molecule made by one X chromosome in every female cell can generate antibodies to a woman's own tissues.

Scientists discover a potential way to repair synapses damaged in Alzheimer's disease

Science Daily - 01/02/2024
While newly approved drugs for Alzheimer's show some promise for slowing the memory-robbing disease, the current treatments fall far short of being effective at regaining memory.

Active components of ginkgo biloba may improve early cognitive recovery after stroke

Science Daily - 01/02/2024
Adults treated with 14 days of intravenous injections of ginkgo diterpene lactone meglumine (GDLM) -- a combination of biologically active components of ginkgo biloba -- after an ischemic (clot-caused) stroke had better cognitive recovery at 14 days and 90 days.

Understanding rapid weight loss in older women: Message from the heart

Science Daily - 01/02/2024
Unexplained rapid weight loss in older people could be a sign of underlying disease and can be linked with increased risk of falls and fractures, as well as a poorer long-term prognosis.

Photonics-based wireless link breaks speed records for data transmission

Science Daily - 01/02/2024
Researchers demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.
