When it comes to starting a family, timing is everything

2023-09-15
The review, conducted jointly with researchers from Oxford University, the Royal Berkshire Hospital in Reading, and the Princess Anne Hospital in Southampton, included seven randomised controlled trials involving 2,464 women or couples who had been trying to conceive. Each month there is a narrow window for successful conception due to the limited lifespan of the sperm and egg, which begins from around five days before ovulation (egg release) and lasts until several hours afterwards. The period of a woman’s cycle can be identified by different methods, including urine ovulation tests (dipstick ...

Are us teenagers more likely than others to exaggerate their math abilities?

2023-09-15
A major new study has revealed that American teenagers are more likely than any other nationality to brag about their math ability. Research using data from 40,000 15-year-olds from nine English-speaking nations internationally found those in North America were the most likely to exaggerate their mathematical knowledge, while those in Ireland and Scotland were least likely to do so. The study, published in the peer-reviewed journal Assessment in Education: Principles, Policy & Practice, used responses from the OECD Programme for International Student Assessment (PISA), in which participants took a two-hour maths test alongside a ...

Women receiving inflated risks from genetic testing could undergo unnecessary breast surgery

2023-09-15
Women could be opting to have unnecessary surgery to avoid breast cancer, after being told they are at high risk from genetic test results which do not take family history into account.  The authors of new research led by the University of Exeter have warned that women who discover,  outside of a clinical setting, that they carry a disease-causing variant in one of the BRCA genes (BRCA1 or BRCA2) may be told their risk of breast cancer is 60-80 per cent. In fact, the risk could be less than 20 per cent if they do not have a close relative with the condition.  The warning has emerged in a paper published today in the Lancet journal eClinical Medicine. Until recently, women who ...

Scientists uncovered mystery of important material for semiconductors at the surface
2023-09-14
A team of scientists with the Department of Energy’s Oak Ridge National Laboratory has investigated the behavior of hafnium oxide, or hafnia, because of its potential for use in novel semiconductor applications. Materials such as hafnia exhibit ferroelectricity, which means that they are capable of extended data storage even when power is disconnected and that they might be used in the development of new, so-called nonvolatile memory technologies. Innovative nonvolatile memory applications will pave the way for the creation of bigger and faster computer systems by alleviating the heat generated from the continual ...

New evidence indicates patients recall death experiences after cardiac arrest

New evidence indicates patients recall death experiences after cardiac arrest
2023-09-14
Philadelphia, September 14, 2023 – Up to an hour after their hearts had stopped, some patients revived by cardiopulmonary resuscitation (CPR) had clear memories afterward of experiencing death and had brain patterns while unconscious linked to thought and memory, report investigators in the journal Resuscitation, published by Elsevier. In a study led by researchers at NYU Grossman School of Medicine, in cooperation with 25 mostly US and British hospitals, some survivors of cardiac arrest described lucid death experiences that occurred while they were seemingly unconscious. Despite immediate treatment, fewer than 10% of the 567 patients studied, ...

Clinical whole genome sequencing test developed at JAX

Clinical whole genome sequencing test developed at JAX
2023-09-14
Until quite recently, it was extremely difficult to detect the variants underlying many genetic disorders. In the absence of a defined cause, clinicians have little to guide treatment for those left without a genetic diagnosis, forcing patients and families to embark on a diagnostic odyssey with no guarantee of finding answers. A decade ago, sequencing centers began offering clinical whole exome sequencing, but these only cover the portion of the genome that codes for proteins – approximately 1.5 percent of the entire genome. While relatively successful, the diagnostic yield for most clinical exome sequencing programs is roughly 25 percent, leaving 75 percent of cases without ...

2023-09-14
PHILADELPHIA (September 14, 2023) – High rates of firearm injury among urban Black men in the U.S. can lead to long physical and psychological recovery times, worsened by limited access to mental health services. In the face of firearm injury, urban Black men may feel they have lost control over their lives, leading to fear, paranoia, lack of forgiveness, and different dimensions of mental health challenges, which can be difficult to overcome. In a pilot study from the  University of Pennsylvania School of Nursing ...

In the ā€œIā€ of the beholder: People believe self-relevant artwork is more beautiful

2023-09-14
People have fairly consistent preferences when it comes to judging the beauty of things in the real world—it’s well known, for example, that humans prefer symmetrical faces. But our feelings about art may be more personal, causing us to prefer art that speaks to our sense of self, research in Psychological Science suggests.  “When there is personal meaning in an image, that can dominate your aesthetic judgments way more than any image feature,” said Edward A. Vessel (The City College of New York) in an interview. Though self-relevant ...

How a molecule deletes neural chat might help treat Angelman syndrome

How a molecule deletes neural chat might help treat Angelman syndrome
2023-09-14
Researchers from the University of Tokyo reveal how the presynaptic Ube3a E3 ligase, a causal factor in Angelman syndrome, eliminates neural chat. The study helps find a better drug target for the Angelman syndrome treatment.  Neurons chat through electrical signals, transmitting information via connection sites between neurons—the synapses. After birth, the number of synapses increases. During childhood, the brain starts to mature and removes many unnecessary synapses. But sometimes, the development of the nervous system goes awry, leading to developmental disorders.  Kotaro ...

In songbirds, complex vocal learning predicts problem-solving abilities and brain size

2023-09-14
Vocal learning complexity, or the ability to imitate sounds, is associated with better problem-solving abilities and larger brains in songbird species, according to a new study. Whether vocal learning complexity was linked with such cognitive phenotypes was previously unknown. The approach used in the study, to study a lineage of birds, serves as a model for testing similar patterns in other vocal learning species. Complex vocal learning – the ability to imitate heard sounds – is a crucial component of human spoken language and has been assumed to be associated with more advanced cognitive abilities. Outside of humans, it has ...

Governance reforms could strengthen the Sustainable Development Goal implementation

2023-09-14
In a Policy Forum, Frank Biermann and colleagues outline demanding – yet realistic – policy reforms to strengthen the governance and implementation of the United Nations’ (UN) ambitious Sustainable Development Goals (SDGs). In 2015, the UN General Assembly agreed on 17 SDGs with 169 targets intended to be achieved by 2030. However, recent research has shown that the political impact of these goals has been limited and has not yet succeeded in reorienting political systems, institutions, or societies ...

Switching off the cytokine storm

Switching off the cytokine storm
2023-09-14
Constant exposure of cells to stressing agents, such as pathogens, may disturb an organism’s normal functioning. To fight stress, cells have developed several coping mechanisms, including the inflammatory response.  While inflammation is necessary, too much of it can impair cell and organ function. This is the case with cytokine storms – inflammatory cascades during an infection that can spiral out of control and lead to severe disease and even death, as recently highlighted during the COVID-19 pandemic. In a new paper published in Science, EMBL Grenoble and University ...

Specialised gut immune cells pinpointed that can limit progression of inflammatory bowel disease

2023-09-14
Researchers at the Francis Crick Institute, King’s College London and Guy’s and St Thomas’ NHS Foundation Trust have characterised a specialised type of immune cell, which plays a key role in protecting and repairing the cells in the healthy human gut. These protective immune cells are depleted in inflammatory bowel disease (IBD), leaving patients vulnerable to disease progression and severe complications. The findings could lead to better clinical management and treatment options for people living ...

Researchers call for major reforms of the UN Sustainable Development Goals: SDG Summit a decisive moment

Researchers call for major reforms of the UN Sustainable Development Goals: SDG Summit a decisive moment
2023-09-14
On 18-19 September, the United Nations will convene a major summit to review the state of the Sustainable Development Goals (SDGs)—the 17 global goals that governments agreed upon in 2015 to guide action towards a prosperous and just future. With research showing that the SDGs have since then had little political impact, the UN Summit must pave the way for four major changes in how the SDGs are implemented and governed globally, argues an international group of experts in Science. The article, based on research led by Utrecht University in the Netherlands, brought together a group of scholars with broad expertise in global sustainability governance. “Our ...

Researchers discover tissue-specific protection against protein aggregation

Researchers discover tissue-specific protection against protein aggregation
2023-09-14
Key points:  Protein aggregation in certain tissues is a hallmark of diseases such as neurodegeneration and occurs during ageing, but little is known about how protein quality control mechanisms acting to prevent toxic protein build-up vary on a tissue-by-tissue basis.  Dr Della David and her team have discovered a safety mechanism that acts to lower levels of protein aggregation in C. elegans pharyngeal muscles, but is not active in body-wall muscles.  This new mechanism was identified by comparing protein accumulation in different tissues in ageing nematode worms when ...

Genetically modified bacteria break down plastics in saltwater

2023-09-14
Researchers have genetically engineered a marine microorganism to break down plastic in salt water. Specifically, the modified organism can break down polyethylene terephthalate (PET), a plastic used in everything from water bottles to clothing that is a significant contributor to microplastic pollution in oceans. “This is exciting because we need to address plastic pollution in marine environments,” says Nathan Crook, corresponding author of a paper on the work and an assistant professor of chemical and biomolecular engineering ...
