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.
URSC is responsible for designing, developing and operationalising space projects, like Chandrayaan-3 and Aditya L-1 missions
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 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.
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 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 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.
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.
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.
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.
Many bacteria form an antibiotic-resistant slime. Research detailing that slime's structure could help lead to new treatments.
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.
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.
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.
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.
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.
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.
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.
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.
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.
