There is a common misperception that widespread marijuana use is limited to younger generations. However, the Baby Boomer generation has reported higher rates of substance use than any preceding generation.
A large analysis of current research shows that people who eat at least 20g of nuts a day have a lower risk of heart disease, cancer and other diseases.
A new scientific review of the winter floods of 2015/2016 confirms that the event was one of the most extreme and severe hydrological events of the last century.
A chemist has designed and synthesized a catalyst that flexibly molds the handedness of the reaction products with which it interacts.
A research team has investigated the expression of ribosomal proteins in a wide range of human tissues including tumors and discovered a cancer type specific signature. This “cancer signature” could potentially be used to predict the progression of the disease.
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA), have for the first time, achieved a precise size measurement of small dust particles around a young star through radio-wave polarization. ALMA’s high sensitivity for detecting polarized radio waves made possible this important step in tracing the formation of planets around young stars.
Researchers show modification of a gene product results in greater physical activity and reduced body weight in mice, thus boosting understanding of how physical activity is regulated at the cellular level in the nervous system.
Plant biologists have developed a genome editing method to knockout target genes in a model plant with high efficiency. The team reports a new CRISPR/Cas9 vector for the model plant that can strongly induce inheritable mutations. This method is expected to become a powerful molecular tool for genome engineering in various plant species.
How do you remember what happened today in the weeks and months that follow? Researchers have answered a piece of that question in a recent study.
Increased stigma and discrimination can affect circadian HPA-axis functioning, say researchers. The majority of previous studies have been conducted among white heterosexuals, with very little research examining HPA-axis functioning between different minorities. Individuals who identify as both sexual and racial minorities may experience increased stigma and discrimination that can affect this HPA-axis functioning. Now, researchers have examined differences in diurnal cortisol rhythm between young, self-identified, white gay men and black gay men.
A new study has revealed similarities and relationships between certain types of chemicals found on 30 different comets, which vary widely in their overall composition compared to one another. The research is part of ongoing investigations into these primordial bodies, which contain material largely unchanged from the birth of the solar system some 4.6 billion years ago.
A researcher wants to scrap the traditional electronic and paper survey approaches to gathering marketing and information systems data in favor of scanning your brainwaves.
Biomarker may predict which formerly treated cancer patients will develop highly fatal form of leukemia
Patients successfully treated for breast, colon and other cancers can go on to develop an often-fatal form of leukemia, sometimes years after completion of treatment, due to a genetic mutation leading to secondary malignancies known as therapy-related myeloid neoplasms (t-MNs).
After one dose of gene therapy, hemophilia B patients maintain near-normal levels of clotting factor
Researchers are reporting the highest and most sustained levels to date of an essential blood-clotting factor IX in patients with the inherited bleeding disorder hemophilia B. After receiving a single dose of an experimental gene therapy in a clinical trial, patients with hemophilia produced near-normal levels of clotting factor IX, allowing them to stop clotting factor infusions and to pursue normal activities of daily life without disabling bleeding episodes.
In a small, early phase trial, a high percentage of patients who had exhausted most traditional treatments for chronic lymphocytic leukemia saw their tumors shrink or even disappear after an infusion of a highly targeted, experimental CAR T-cell immunotherapy.
Endangered leatherback sea turtles are known for their open-ocean migratory nature and nomadic foraging habits -- traveling thousands of miles. But a naturalist and his colleagues have discovered an area along the Mozambique coast that the turtles have made their permanent home, according to a study.
In nanotechnology, control is key. Control over the arrangements and distances between nanoparticles can allow tailored interaction strengths so that properties can be harnessed in devices such as plasmonic sensors. Now researchers use dendrimers that mimic the electron valency of atoms and link them into arrays using molecules that coordinate with the dendrimer as they would form a covalent electron pair in their valence shell - "electron pair mimicry".
Researchers have recently developed a new ultra-low-friction sliding contact mechanism that uses chilled water to remove heat from a key component of a next-generation collider.
People with schizophrenia who have difficulty hearing subtle changes in pitch may be helped with auditory training exercises and a drug that targets NMDA receptors in the brain, report researchers.
Experiments using laser light and pieces of gray material the size of fingernail clippings may offer clues to a fundamental scientific riddle: What is the relationship between the everyday world of classical physics and the hidden quantum realm that obeys entirely different rules?
