Research finds global emissions of several banned ozone-destroying chemicals are increasing
2023-04-03
The research, published today in Nature Geoscience and led by the University of Bristol and National Oceanic and Atmospheric Administration (NOAA), puts the rise in part down to the chemicals, known as chlorofluorocarbons or CFCs, being used to make other ozone-friendly alternatives to CFCs. This is an exception allowed under the Montreal Protocol, but contrary to its wider goals.
Lead author Dr Luke Western, a Research Fellow at the University of Bristol and researcher at the NOAA’s Global Monitoring Laboratory (GML), said: “We’re paying attention to these emissions now because of the success of the Montreal Protocol. CFC ...
Early menopause, later start to hormone therapy may increase risk of Alzheimer’s disease
2023-04-03
BOSTON — Women are more likely than men to develop Alzheimer’s disease (AD), with women making up two-thirds of the population living with AD. A new study, led by Mass General Brigham researchers, sheds light on the relationship between the risk of Alzheimer’s disease and age of menopause and use of hormone therapy (HT). The results, published in JAMA Neurology, indicate that early age at menopause may be a risk factor for AD dementia, but that women who were prescribed HT around the age of menopause onset did not show increased risk.
“HT is the most reliable way to ameliorate severe menopause symptoms, ...
Comparison of postpartum opioid prescriptions before vs during pandemic
2023-04-03
About The Study: In this study of 460,000 privately insured postpartum women, patients who gave birth to a single, live newborn after March 2020 were more likely to fill more potent and more frequent opioid prescriptions than patients who gave birth prior to March 2020. Increases were larger for patients delivering via cesarean birth than those delivering vaginally. Increases in opioid prescriptions may be associated with increased risk of opioid misuse, opioid use disorder, and opioid-related overdose among postpartum women.
Authors: Shelby R. Steuart, M.P.A., of ...
Genetics of preterm birth and pregnancy length clarified
2023-04-03
New knowledge of the genetic factors behind premature delivery and gestational duration has now emerged. Findings presented by a major international study under the aegis of the University of Gothenburg include the ways in which, before birth, the woman’s and the unborn child’s genes have mutually antagonistic effects.
These results, now published in the journal Nature Genetics, enhance the potential for long-term development of drugs to induce parturition (birth) and — even more importantly — achieve the goal of preventing preterm births.
Globally, preterm (or premature) birth is the most frequent immediate cause of death among newborns and children ...

2023-04-03
The number of prostate cancer patients in the U.S. choosing active surveillance over surgery or radiation has rapidly increased since 2010, rising from 16% to 60% for low-risk patients and from 8% to 22% for patients with favorable intermediate-risk cancers, according to a study published today in JAMA Internal Medicine.
Active surveillance includes actively monitoring prostate cancer for progression, with the intention to intervene with surgery or radiation therapy if the cancer progresses.
It is the preferred treatment option for men with low-risk ...
Double-slit experiment that proved the wave nature of light explored in time
2023-04-03
Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space.
The experiment relies on materials that can change their optical properties in fractions of a second, which could be used in new technologies or to explore fundamental questions in physics.
The original double-slit experiment, performed in 1801 by Thomas Young at the Royal Institution, showed that light acts as a wave. Further experiments, however, showed that light actually ...

Anticancer drugs with fewer side-effects: scientists decode the crystal structure of a key cell cycle protein
2023-04-03
Anticancer drugs are pivotal to cancer treatment, but their toxicity may not always be limited to cancer cells, resulting in harmful side-effects. To develop anticancer therapies that have fewer adverse effects on patients, scientists are now focusing on molecules that are less toxic to cells. One such group of drugs is the "kinesin inhibitors." These inhibitors prevent cancer progression by explicitly targeting kinesin motor proteins, which are required for the division of cancer cells. Centromere-associated protein E (CENP-E), a member of the kinesin motor protein, is a promising target for inhibitor therapy, as it is essential for tumor cell replication. However, determining the ...
Researchers reviewed recent progress of organic room-temperature phosphorescent materials towards application
2023-04-03
Organic materials with room-temperature phosphorescence (RTP) emission have attracted extensive attention due to extraordinary properties including long lifetime, large Stokes shift, stimuli-responsiveness, and so on, and show bright prospects in broad fields. However, the energy of the excited state of organic phosphors is easily consumed through thermal radiation and collision deactivation. Therefore, numerous design strategies such as creating a rigid environment through crystallization and supramolecular assembly are employed to improve the luminescent characteristics of RTP materials by restricting nonradiative transition, enhancing intersystem crossing, and so forth. A team ...

Jet lag’s harmful health impacts found to be caused by biological clock misalignment
2023-04-03
New research at the University of Massachusetts Amherst zeroes in on the root cause of adverse health effects from disruption of the body’s circadian rhythms, which typically occurs from jet lag and rotating work shifts.
The research, published in the journal eNeuro, also shows that the circadian clock gene Cryptochrome 1 (Cry 1) regulates adult neurogenesis – the ongoing formation of neurons in the brain’s hippocampus. Adult neurogenesis supports learning and memory, and its disruption has been linked to dementia and mental illness.
“Circadian disruption impacts a lot of things,” says lead author Michael Seifu Bahiru, a Ph.D. candidate in the ...

Older adults perceive artificial intelligence as more human-like than younger adults do
Toronto, April 3, 2023 – Artificial intelligence (AI) is increasingly present in all of our lives, from newer offerings like ChatGPT to more established voice systems such as automated phone services, self-checkouts, Apple’s Siri and Amazon’s Alexa. While these technologies largely benefit us, they can also be used in adverse ways – for instance, in fraudulent or scam calls – making it important for us to be able to identify them.
According to a recent Baycrest study, older adults appear to be less able to distinguish ...
E-health reduces patient pain, opioids in clinical study
2023-04-03
SPOKANE, Wash. – An online “e-health” program helped more people with chronic pain reduce their opioid medications and pain intensity than a control group that had only regular treatment in a recent clinical study.
In the study published in the journal Pain, about 400 participants who had been prescribed long-term opioid treatment for their pain were divided into two groups: one received treatment as usual and another received treatment and access to a self-guided, e-health program. Of the e-health group, more than half, 53.6%, were able to reduce their ...
Purified curcumin instead of artificial additives can be used to preserve and enhance probiotic yogurt

Researchers have succeeded for the first time in adding a highly purified form of curcumin to yogurt in a way that ensures it remains dissolved in the dairy product and preserves it, while tasting good.
Their discovery, which is published today (Monday) in Frontiers in Nutrition, makes it possible to create a probiotic yogurt that contains no artificial preservatives but that still has a long shelf life and properties that may enhance good health.
Curcumin is a naturally-occurring chemical that provides the yellow colour in turmeric. Studies have shown that it has anti-inflammatory and anti-oxidative properties, that it can inhibit the growth ...
English language pushes everyone – even AI chatbots - to improve by adding
2023-04-03
A linguistic bias in the English language that leads us to ‘improve’ things by adding to them, rather than taking away, is so common that it is even ingrained in AI chatbots, a new study reveals.
Language related to the concept of ‘improvement’ is more closely aligned with addition, rather than subtraction. This can lead us to make decisions which can overcomplicate things we are trying to make better.
The study is published today (Monday 3rd April) in Cognitive Science, by an international ...
Privately sponsored refugees likely to receive better prenatal care than government-assisted refugees in Canada
2023-04-03
Government-assisted refugees were less likely to receive adequate prenatal care than privately sponsored refugees, found a new study published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.221207.
