A new laser-based system has been developed to detect and measure the levels of all biomolecules, including proteins, sugars, fats, and their derivatives. This technique offers unparalleled sensitivity and can be used for all known classes of biomolecules, enabling the detection of precancerous and malignant cells in body fluids.
A new study assesses country and regional progress towards 17 UN Sustainable Development Goals (SDGs), revealing disparities between developed and developing regions. The study suggests that sustainability progress is dynamic and may involve tradeoffs, highlighting the need for a holistic approach to address these challenges.
Researchers from Oklahoma State University Center for Health Sciences studied two mid-sized, immature T. rex skeletons to understand the tyrant king's teenage years. The team found that the small T. rex were growing as fast as modern-day warm-blooded animals and underwent drastic changes as they matured.
Researchers from Washington University in St. Louis and Argonne National Laboratory have successfully reversed the flow of electrons in a purple photosynthetic bacteria, achieving a 90% yield on the B-branch side. This breakthrough discovery sheds light on the earliest light-driven events of photosynthesis and could aid in designing bi...
A new study refutes the idea that small Tyrannosaurus rex specimens represent a separate genus, instead revealing they were juvenile versions of their larger counterparts. The research found evidence of rapid growth in these young T. rexes, suggesting they likely played different roles in their ecosystems than adults.
A new noninvasive diagnostic method using circulating tumor DNA can detect colorectal cancer in at-risk patients with high accuracy. The technology, developed by Huiyan Luo et al., uses methylation markers to identify patients with a sensitivity and specificity of 87.5% and 89.9%, respectively.
New research reveals anti-abortionists using civil rights protections to lobby against early abortions. Pro-lifers compare fetuses to Black Americans and LGBTQIA people to strengthen their case, misrepresenting medical facts in the process.
A new study finds that tau protein is a more reliable predictor of brain atrophy in Alzheimer's patients than amyloid plaques. Tau PET imaging technology has the potential to accelerate clinical trials and improve individualized patient care.
Researchers found that intravenous BCG vaccination significantly increased protection against TB in rhesus macaques. The study showed that IV BCG elicited strong, sustained T cell responses in the lungs, leading to a high degree of protection against infection and disease.
A new study found that delivering the TB vaccine intravenously dramatically improves its potency, offering nearly full protection against TB in monkeys. The vaccine was highly effective when administered via injection into a vein, reducing bacterial burden by 100,000-fold and inflammation in lungs to near zero.
A new study has shown that a protein therapy called rhPDGF-AB can improve the quality of scar tissue after a heart attack, leading to the formation of new blood vessels and reduced rates of dangerous heart arrhythmia. The treatment has increased survival rates in animal models and holds promise for improving patient outcomes.
Researchers found that annual river ice cover will decline by about six days for every one degree Celsius increase in global temperatures, affecting communities and industries. The study also detected widespread declines in monthly river ice coverage, particularly in the Tibetan Plateau, eastern Europe, and Alaska.
