A newly discovered neural circuit mediates between navigational brain cells, acting as a sort of mental steering wheel.
The CRISPR system in bacteria serves as a warehouse for past infections by storing a part of the viral genetic material and incorporating it into its own, so the next time it is attacked, the bacteria is capable of recognising the virus and destroying it
This week Sci-Five’s quiz is on wetlands.
The satellite will spend at least three years studying the oceans from 420 miles (676 kilometers) up, as well as the atmosphere.
Scientists at C3S said the global mean temperature for the past 12 months (February 2023-January 2024) was the highest on record and 1.52 degrees Celsius above the 1850-1900 pre-industrial average
Research shows that phthalates, a class of chemicals associated with plastics, can shed from the wrapping, packaging and even from plastic gloves worn by food handlers into food. Once consumed during pregnancy, the chemicals can get into the bloodstream, through the placenta and then into the fetal bloodstream. The chemical can cause oxidative stress and an inflammatory cascade within the fetus, researchers noted. Previous literature has indicated that exposure to phthalates during pregnancy can increase the risk of low birth weight, preterm birth and child mental health conditions such as autism and ADHD.
African demand for rice is projected to more than double during the next 25 years because of population growth and increased rice consumption. A research project shows that the average yield for Africa's rice sector represents less than half the yield that could be achieved with improved agronomic practices. That means African farmers have the ability to significantly increase crop production without tilling more land.
A tiny microfluidic device can improve cell therapy techniques for spinal cord injury patients. The device can remove a large percentage of stem cells that have not yet fully become spinal cord cells, which could potentially form tumors after being transplanted into a patient.
The same phosphorus that fertilizes the thriving agriculture of the Midwest is also responsible for a vast 'dead zone' in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked -- and lingering -- problem.
Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.
Inspired by ChatGPT's popularity and wondering if this approach could speed up the drug design process, scientists decided to create their own genAI model. Scientists coded a model to learn a massive dataset of known chemicals, how they bind to target proteins, and the rules and syntax of chemical structure and properties writ large. The end result can generate countless unique molecular structures that follow essential chemical and biological constraints and effectively bind to their targets -- promising to vastly accelerate the process of identifying viable drug candidates for a wide range of diseases, at a fraction of the cost.
Researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user's earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.
A new BU CTE Center paper connects cognitive and behavioral symptoms to protein buildup in the brain that marks the disease.
A study in fruit flies reveals how the brain's compass and steering regions make course corrections.
Scientists discovered a novel self-perpetuating cancer mechanism in the lung microenvironment, wherein EGFR-driven lung adenocarcinoma cells exploit lung-resident macrophages -- remodeling them to provide nutrients, like cholesterol, to the cancer cells and stimulate tumor growth. Their findings provide new inspiration for lung adenocarcinoma interventions that disrupt this tumor cell-macrophage relationship, as well as suggest that existing EGFR inhibitor treatments may be more successful if paired with statins.
An international team of scientists has created a tool that can aid in increasing climate awareness and climate action globally by highlighting messaging themes shown to be effective through experimental research.
Tiny external structures in the wax coating of blueberries give them their blue color, researchers reveal.
Researchers have made a groundbreaking discovery: a new cell that remembers allergies.
The speed at which England's oldest adults became frailer accelerated during the UK Government's era of austerity politics, according to a new study.
The drugs used to treat erectile dysfunction may also be associated with a reduced risk of Alzheimer's disease, according to new research. The study does not prove that erectile dysfunction drugs reduce the risk of Alzheimer's disease. It only shows an association.
