Destructive winds during storms and cyclones often cause tree failures, especially through uprooting and stem breakage. However, how trees respond to wind under various forest configurations and weather conditions remains unclear. A recent study on Cryptomeria japonica plots shows that trees dissipate wind energy by switching between two swaying behaviors at specific wind speeds, offering insights that may help in improved forest management to minimize damage caused by storms. Extreme weather events, such as tropical and extratropical cyclones and tornadoes, can cause widespread damage to forests, leading to environmental and financial ...

Bioprinting is a technology used to create three-dimensional structures, such as human tissues or organs, using bio-inks made of cells and hydrogels. However, conventional inkjet technology has difficulty dispensing bio-inks that are sensitive to temperature due to the heat generated during operation. Furthermore, conventional 3D bioprinting mainly utilizes simple syringe-type printing devices with a single needle, making it time-consuming to produce artificial organs like the brain, lungs, and heart. The Bionics Research Center team, led by Dr. Byung Chul Lee at the Korea Institute of Science and Technology (KIST, President Sang-Rok Oh), in ...

People inherit two copies of each gene — one from each parent — an evolutionary fail-safe to ensure survival even when one of them doesn’t function. For cancer-suppressor genes like BRCA1, researchers have long hypothesized that a single healthy copy could still guard against tumor development. Yet women with one harmful BRCA1 mutation are far more likely to develop breast cancer — a risk traditionally explained by a second mutation that arises later in life, damages the healthy copy of the gene, ...

AMES, Iowa – In their long strings of nucleotides, DNA molecules hold massive troves of genetic data providing instructions for how living organisms should function – the blueprint of life. How the blueprint is stored, however, impacts how it is read and used. As cells divide and replicate, DNA strands coiled around proteins – chromatin – are in tightly bundled chromosomes. After division, the chromosomes loosen and chromatin is less compact. How and where the chromatin fiber folds and ...

Adolescents who meet the recommended guidelines of nine to 11 hours of sleep per day were shown to have a significantly lower risk of hypertension, according to a new study from UTHealth Houston.   Recently published in the Journal of the American Heart Association, the research revealed that adolescents had a 37% lower risk of developing incidents of high blood pressure by meeting healthy sleep patterns, and underscoring the importance of adequate sleep behavior.

How would you summarize your study for a lay audience?  T helper (TH) cells are essential immune cells that help other immune cells function effectively. When activated in response to environmental stimuli, these cells can differentiate into either TH1 cells, which fight against viruses and intracellular pathogens, or TH2 cells, which fight against extracellular pathogens like bacteria and parasites. However, scientists haven’t fully understood whether infected tissue itself has any role in directing the optimal T cell differentiation in response ...

Current guidelines recommend that pregnant people receive a vaccine against respiratory syncytial virus (RSV)—which typically causes mild, cold-like symptoms in most adults but can be deadly for infants—during weeks 32–36 of pregnancy. New research led by investigators at Mass General Brigham suggests that vaccination earlier in that timeframe, closer to 32 weeks, could provide the best protection for newborns against RSV. The findings are published in the American Journal of Obstetrics & Gynecology. “Receiving ...
