Recently, a joint Chinese–American research team led by Dr. HU Han from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and Dr. Jingmai O’Connor from the Field Museum of Natural History (Chicago

A joint Chinese-American research team has discovered the smallest known Archaeopteryx specimen, acquired by the Field Museum in 2022. The study provides crucial insights into the evolution of the skull and adaptations for flight during the transition from non-avian dinosaurs to birds.

Stretched in a cross pattern: Our neighboring galaxy is pulled in two axes

Researchers at Nagoya University discovered that Cepheid variable stars in the Small Magellanic Cloud are moving in opposing directions along two distinct axes, indicating the galaxy is being stretched by multiple external gravitational forces. The findings challenge previous theories of the galaxy's structure and dynamics.

Large study traces prehistoric human expansion into South America, where genomic studies have been lacking

A large genomic study reveals distinct ancestry patterns and early diversification of Indigenous South American populations. The study suggests northern and southern Native American groups diverged between 17,500 and 14,600 years ago, with human presence in southernmost South America confirmed by 14,500 years ago.

Successful snus cessation led to increased body weight and blood pressure

Researchers found that snus cessation led to a clinically significant rise in blood pressure, averaging 3.7 mm Hg, and weight gain of 1.8 kilos in a group of 33 participants. The study suggests that healthcare professionals should monitor blood pressure after snus cessation, especially for individuals with cardiovascular problems.

“Chicago archaeopteryx” unveiled: New clues on dinosaur–bird transition revealed by Chinese–American research team

The study provides crucial insights into the evolution of the skull and adaptations for flight in the critical transition from non-avian dinosaurs to birds. The Chicago Archaeopteryx specimen reveals an almost completely preserved skull with a palatal region intermediate between troodontids and more derived Cretaceous birds.

Implanting Ag nanoparticles in SiOC ceramic nanospheres for exceptional electromagnetic wave absorption and antibacterial performance

Scientists have created a new class of materials that absorb electromagnetic waves and exhibit strong antibacterial properties. The researchers used liquid phase method to implant Ag nanoparticles in SiOC ceramic nanospheres, achieving an absorption performance of -58.03 dB and effective antibacterial ability against E. coli and S.aureus.

How do plants “otify” their neighbors in danger?

When plants are infected by pathogens, attacked by herbivores, or suffer from mechanical damage, mycorrhizal fungi can transmit warning signals to neighboring individuals via extensive symbiotic relationships. This process allows plants to activate defense mechanisms and reduces the risk of being attacked.

Study suggests loss of lung capacity begins between the ages of 20 and 25

A study published in The Lancet Respiratory Medicine found that lung capacity develops in two phases: rapid growth during childhood and slower growth until peak lung function. Lung function starts to decline after the peak age, contrary to previous models. Persistent asthma and smoking affect lung function differently than thought.

UT MD Anderson and Texas Children’s Hospital announce $150 million gift from Kinder Foundation to launch Kinder Children’s Cancer Center

The $150 million gift from Kinder Foundation will create a joint venture between UT MD Anderson Cancer Center and Texas Children's Hospital, aiming to end childhood cancer. The center will be the nation's largest and most comprehensive pediatric cancer center focused exclusively on children.

Genetic ancestry and parental smoking linked to new genetic changes in children

Research reveals that different ancestry groups have varying rates of new genetic mutations passed to children, with African groups showing a higher rate. Additionally, parental age, especially paternal age, significantly impacts the number of new genetic mutations, while parental smoking is linked to a small increase in mutation count.

VR flight experience reduces fear of heights by action-based prediction of safety

A VR flight experience has been shown to reduce both physiological and subjective fear responses to heights. The degree of fear reduction correlates with the extent to which participants felt they could transition to a safe state through self-initiated actions.

Autistic people communicate just as effectively as others, study finds

Researchers found that social difficulties faced by autistic individuals are primarily due to differences in communication styles, rather than a lack of social ability. Autistic people often communicate more directly, but struggle with reading social cues, leading to varying conversation dynamics compared to non-autistic peers.
