While the impact of wildfires on terrestrial life has been well studied, only recently has research started to examine the effects of wildfire ash on aquatic organisms. New research reveals that wildfire ash can have lethal consequences on Australian water ecosystems. Wildfires are becoming more prevalent due to the warming and drying effects of climate change, with Australia becoming especially vulnerable to dangerous bushfires. “Therefore, many Australian species may be threatened by fires,” says Miss Jenelle McCuaig, a Masters student at the University ...

Researchers have recently developed a flexible-yet-sturdy morphing structure inspired by the starfish skeleton that exhibits 4D morphing features with promising applications for robotics, aviation, and medical devices. “Starfish possess the remarkable ability to effortlessly hold themselves in any body posture by changing the stiffness of their endoskeleton,” says Raman, a PhD student in the Biological Structures and Biomimetics workgroup at Hochschule Bremen - City University of Applied Sciences Bremen, Germany.  Ossicles are calcite microstructures inside starfish bodies that are connected in a ...

Chicago (July 2, 2024) — A new study found that school-aged children who consumed more isoflavones from soy foods exhibited better thinking abilities and attention. These findings pave the way for future research aimed at unraveling how soy foods can positively impact children's cognitive abilities. Isoflavones are naturally occurring compounds found in various plants, particularly soybeans and soy products. Although previous research in adults has suggested that soy isoflavones can improve memory, the ...

The journal is published in the Lippincott portfolio by Wolters Kluwer.  "Despite an upward trend in reconstruction, AI/AN women continue to be less likely to undergo breast reconstruction," comments Jane Hui, MD, MS, ...

A modeling study suggests that influential neighbors can be as effective as despotic leaders at promoting social cooperation. Prosocial behaviors can be difficult to sustain in large societies over the long term, as people give into the temptation to defect to strategies that prioritize the wellbeing of themselves and their immediate family. Stefani Crabtree and colleagues constructed a general theoretical framework to explore how cooperation could arise and be maintained in a large society. The authors explore three possible ...

Mill Valley, CA – June 18, 2024 SRF has established a dedicated account to support research regarding SYNGAP1 missense variants.  This account is being launched with a $10,000 donation from Dennis and Janet Nordmoe. This is a cause close to their hearts, as their granddaughter Olivia was diagnosed with SYNGAP1-Related Disorder (SRD) caused by a missense variant earlier this year. Missense Research: Neglected to Date “Most diagnosed SYNGAP1-Related Disorder (SRD) patients have protein truncating variants (PTV) as opposed to missense variants. Virtually all PTVs are assumed to have the ...

Three-dimensional (3D) imaging of organs and tissues is vital as it can provide important structural information at the cellular level.  3D imaging enables the accurate visualization of tissues and also helps in the identification of pathological conditions. However, achieving successful 3D imaging necessitates specific prerequisites, including the preparation of 'cleared' tissue samples—biological specimens rendered transparent by removing light-scattering components like lipids to ...

In recent decades, single-use plastics have pervaded modern societies, causing a significant surge in plastic pollution that exacts a heavy toll on our environment. Addressing this issue requires prioritizing sustainable alternatives to single-use plastics wherever feasible. Disposable menstrual products are a notable contributor to plastic waste, with billions of sanitary napkins and tampons being discarded every year. Despite the availability of sustainable options like menstrual cups (MCs), consumer preference for single-use products ...

Who’s stronger? A solitary leopard or cackle of hyenas? And which is best at getting along with humans? University of Copenhagen researchers closely studied this in a large East African natural area surrounded by rural settlements. The study demonstrates that the presence of humans has a direct impact on the competitive relationship between the two large predator species: leopards (Panthera pardus) – the iconic spotted feline and the spotted hyena (Crocuta crocuta) – a kleptoparasite and pack hunter known for its comical ...

The reality of the climate impact of long-distance passenger travel has been revealed in new research from the University of Leeds. Despite only accounting for less than 3% of all trips by UK residents, journeys of more than 50 miles (one way) are responsible for 70% of all passenger travel-related carbon emissions. The disparity is even greater when international travel is singled-out: international journeys are only 0.4% of total trips but are responsible for 55% of emissions. The new research, published today in the journal Nature Energy, also shows ...

Whole genome sequencing has improved clinical care of some children with cancer in England by informing individual patient care. New research from the Wellcome Sanger Institute, Cambridge University Hospitals NHS Trust, Great Ormond Street Hospital, and the University of Cambridge, supports the efforts to provide genome sequencing to all children with cancer and shows how it can improve the management of care in real-time, providing more benefits than all current tests combined. The study, published today (2 July) in Nature Medicine, ...

ROCHESTER, Minn. — Drugs that selectively kill senescent cells may benefit otherwise healthy older women but are not a "one-size-fits-all" remedy, Mayo Clinic researchers have found. Specifically, these drugs may only benefit people with a high number of senescent cells, according to findings publishing July 2 in Nature Medicine. Senescent cells are malfunctioning cells in the body that lapse into a state of dormancy. These cells, also known as "zombie cells," can't divide but can drive chronic inflammation and tissue dysfunction linked to aging and chronic ...

New Lab Test to Detect Persistent HIV Strains in Africa May Aid Search for Cure A multinational team led by Weill Cornell Medicine investigators developed a test that will help measure the persistence of HIV in people affected by viral strains found predominantly in Africa—a vital tool in the search for an HIV cure that will benefit patients around the world. The study, published in Nature Communications on July 2, helps fill a major gap in human immunodeficiency virus (HIV) research. Most HIV studies have focused on strains circulating in Western countries, predominantly ...

Milan, July 2, 2024 - Combating future pandemics through data analysis of recombinant virus genomes. A study published in the prestigious journal Nature Communication presents the promising results of RecombinHunt, a new data-driven method developed by the Department of Electronics, Information and Bioengineering of the Politecnico di Milano and the University of Milan, which can identify, with high accuracy and computational efficiency, recombinant SARS-CoV-2 genomes with one or two breakpoints.

The sea worm Platynereis dumerilii is only a few centimetres long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm’s tail, a research team led by a CNRS scientist1 has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis. Even more surprising, the team found that this ability of gut cells to regenerate other tissue varies according to their location: the closer they are to the posterior end of the ...

Genoa (Italy)/Grenoble (France) – 2nd July, 2024 - The correct functioning of cells relies heavily on the ability to finely control gene expression, a complex process by which the information contained in DNA is copied into RNA to eventually give rise to all the proteins and most of the regulatory molecules in the cell. If DNA can be imagined as a dense technical manual, gene expression is the method by which the cell extracts useful information from it. Researchers at the Istituto Italiano di Tecnologia (IIT) in Genoa and the European Molecular Biology Laboratory (EMBL) in ...

Like most primates, humans are remarkably touchy-feely. Starved of touch, we release more of the stress hormone cortisol, which causes the immune system to be down-regulated and the heart rate and blood pressure to go up. On the other hand, touch causes the brain to be flooded by natural opioids, the ‘bonding hormone’ oxytocin, and the ‘feel-good’ neurotransmitters dopamine and serotonin. It is generally assumed that our sense of touch worsens with age, just like our vision and sense of hearing. However, new results are good news for those who wished they could stave off age-related decline forever: they show for the first time that a deterioration ...

Tumors arising in the base of the skull are among the most difficult to remove in neurosurgery. The current treatment method is to perform surgical removal by what is known as the microscopic anterior transpetrosal approach (ATPA). Seeking to lessen the risk of damage and postoperative complications, as the skull base is densely packed with nerves, blood vessels, and other tissues, not to mention the brain stem, an Osaka Metropolitan University medical research team is taking a new approach. Led by Dr. Hiroki Morisako, a lecturer in ...

Transgender, nonbinary, and gender-diverse people face barriers to accessing surgery and to the health system in general, describe authors in two new research papers published in CMAJ (Canadian Medical Association Journal). In many areas of life, people who identify as transgender, nonbinary, and gender diverse experience discrimination even where there are laws to protect transgender human rights. Health systems also pose barriers for transgender, nonbinary, and gender-diverse people, who are more likely to delay obtaining ...

Extreme weather events such as hurricanes and storms have increased in both frequency and severity in recent years. With that has come heightened public interest, resulting in often dramatic footage being live-streamed on platforms such as YouTube, TikTok and Discord. Now, a new study conducted at the University of Plymouth has for the first time analysed what might be motivating people to watch these streams – in some instances for up to 12 hours at a time. The research centred around the live-streaming ...

A new study of coral reefs in Papua New Guinea shows ocean acidification simplifies coral structure, making crucial habitat less appealing to certain fish species. While much media attention has focused on heat stress-induced coral bleaching, this finding, by a University of Adelaide research team led by Professor Ivan Nagelkerken, adds nuance to concerns about how global warming affects coral reefs. Ocean acidification is caused by an increase in the level of carbon dioxide in oceanwater, leading to a reduction in pH. This makes calcium carbonate less available in the ocean, which corals use to build and repair their skeleton. Professor Nagelkerken and ...

Athletes and sporting teams have frequently used the Olympics and other sporting events to make political statements through boycotts and protests. Ahead of the Paris Olympics kicking off this month and amidst the current UEFA (Union of European Football Associations) European Football Championship (Euro 2024), researchers are asking – should sport be a platform for promoting social justice issues? The 2024 Paris Olympics, like the Euro 2024 soccer tournament, will be watched by billions of people and command media attention around the globe. ...
