Scientists from the International Centre for Radio Astronomy Research (ICRAR) and The University of Western Australia (UWA) have set a world record for the most stable transmission of a laser signal through the atmosphere.
In a study published today in the journal Nature Communications, Australian researchers teamed up with researchers from the French National Centre for Space Studies (CNES) and the French metrology lab Systèmes de Référence Temps-Espace (SYRTE) at Paris Observatory.
A new study from the Institut de Ciències del Mar (ICM-CSIC, Spain) and the National Oceanography Centre brings unprecedented insights into the environmental constraints and climatic events that controlled the formation of these reefs.
The results of this research will help understand how cold-water coral reefs can react to the effects caused by the present-day climate change.
Breast cancer investigators in the Lambe Institute at NUI Galway have collaborated on a pivotal international study into breast cancer risk which was published in the New England Journal of Medicine today (Wednesday, 20 January). The results of the study have identified that there are nine specific genes associated with breast cancer risk.
COVID-19 has been spreading rapidly over the past several months, and the U.S. death toll has now reached 400,000. As evident from the age distribution of those fatalities, COVID-19 is dangerous not only for the elderly but for middle-aged adults, according to a Dartmouth-led study published in the European Journal of Epidemiology.
A phase 2 clinical trial providing personalized treatments based on the genetic profile of metastatic tumors in gastroesophageal cancers has found that using customized treatment approaches, and adapting them over time as tumors become resistant, led to higher rates of survival compared to historical controls. The final results were published online on Jan. 21 in Cancer Discovery, a journal of the American Association for Cancer Research.
ROCHESTER, Minnesota -- A new multi-institution study led by Fergus Couch, Ph.D., a Mayo Clinic pathologist, provides more accurate estimates of breast cancer risk for U.S. women who harbor inherited mutations in breast cancer predisposition genes. The findings of the CARRIERS Consortium study, which were published Wednesday, Jan. 20 in the New England Journal of Medicine, may allow health care providers to better assess the risk of breast cancer in women ? many of whom have no family history of breast cancer ? and provide more appropriate risk management strategies.
PROVIDENCE, R.I. [Brown University] -- When sheets of two-dimensional nanomaterials like graphene are stacked on top of each other, tiny gaps form between the sheets that have a wide variety of potential uses. In research published in the journal Nature Communications, a team of Brown University researchers has found a way to orient those gaps, called nanochannels, in a way that makes them more useful for filtering water and other liquids of nanoscale contaminants.
TROY, N.Y. -- Warnings about misinformation are now regularly posted on Twitter, Facebook, and other social media platforms, but not all of these cautions are created equal. New research from Rensselaer Polytechnic Institute shows that artificial intelligence can help form accurate news assessments -- but only when a news story is first emerging.
Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it's not much fun for the trout.
Scientists at Oregon State University have found that sampling stream water for evidence of the presence of various species using environmental DNA, known as eDNA, can be more accurate than electrofishing, without disrupting the fish.
If you believe you are capable of becoming the healthy, engaged person you want to be in old age, you are much more likely to experience that outcome, a recent Oregon State University study shows.
"How we think about who we're going to be in old age is very predictive of exactly how we will be," said Shelbie Turner, a doctoral student in OSU's College of Public Health and Human Sciences and co-author on the study.
DAVIS, Calif., January 21, 2020 - A new peer-reviewed study reveals that the vast majority of U.S. infants may be suffering from a substantial deficiency in an important bacterium key to breast milk utilization and immune system development, as well as protection against gut pathogens linked to common newborn conditions such as colic and diaper rash.
Just like us, many insects need a decent night's sleep to function properly, but this might not be possible if they have been exposed to neonicotinoid insecticides, the most common form of insecticide used worldwide, suggests research by academics at the University of Bristol.
Two studies by scientists at Bristol's Schools of Physiology, Pharmacology and Neuroscience and Biological Sciences have shown these insecticides affect the amount of sleep taken by both bumblebees and fruit flies, which may help us understand why insect pollinators are vanishing from the wild.
Researchers from the University of Cambridge have discovered a fossil of the earliest starfish-like animal, which helps us understand the origins of the nimble-armed creature.
The prototype starfish, which has features in common with both sea lilies and modern-day starfish, is a missing link for scientists trying to piece together its early evolutionary history.
MINNEAPOLIS - A new study shows that intense immunosuppression followed by a hematopoietic stem cell transplant may prevent disability associated with multiple sclerosis (MS) from getting worse in 71% of people with relapsing-remitting MS for up to 10 years after the treatment. The research is published in the January 20, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study also found that in some people their disability improved over 10 years after treatment.
Methamphetamine overdose deaths surged in an eight-year period in the United States, according to a study published today in JAMA Psychiatry. The analysis revealed rapid rises across all racial and ethnic groups, but American Indians and Alaska Natives had the highest death rates overall. The research was conducted at the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.
