Coastal forests in Japan had predominantly been afforested with black pine (Pinus thunbergii), a shade-tolerant tree species that can withstand dry land ecosystems and harsh coastal environments. This afforestation initiative, dating back to the Edo period (1603~1867), aimed to mitigate the deleterious effects of robust winds and sand blowing. Subsequent to the Great East Japan Earthquake in 2011, interest shifted to the potential protective effects of coastal forests in reducing the destructive power of tsunamis. The Great East Japan Earthquake tsunami damaged a total of 2,800 hectares (ha; 10,000 square meters) of ...

D'Or Institute for Research and Education (IDOR) played an important role in the phase III LIBRETTO-431 multicenter study, which evaluated the efficacy and safety of selpercatinib compared to control treatment, which consisted of platinum-based chemotherapy associated or not with pembrolizumab (immune checkpoint inhibitor) in non-small cell lung cancer (NSCLC). The research was published in the New England Journal of Medicine (NEJM), one of the most important scientific publications in the medical field, and included Dr. Milena Perez Mak, IDOR researcher and clinical oncologist at ...

Compounds that obstruct the "landing gear" of a range of harmful viruses can successfully protect against infection by the virus that causes COVID-19, a study published today and led by Dana-Farber Cancer Institute scientists shows.  Based on the findings, researchers have launched a human clinical trial of one such compound made by chemically stabilizing a key coronavirus peptide. If the compound, called a stapled lipopeptide, proves effective as a nasal spray in the trial, it could be the basis for a new drug modality to prevent or treat COVID-19, say the authors of the study, posted online today in the journal Nature ...

With the start of a new year, smokers and vapers may have resolved to quit or cut back on the habit to improve their health. They may want to use caution, however, if their strategy involves switching from cigarettes to e-cigarettes, considered by some to be a less harmful alternative. A new study from the University of Louisville shows the nicotine in certain types of e-cigarettes may be more harmful than others, increasing risk for irregular heartbeat, or heart arrhythmias. A popular claim is that nicotine in ...

About The Study: This study of 620,000 children found that maternal type 1 diabetes was associated with increased risk for most types of congenital heart defects in offspring, while obesity and overweight were associated with increased risk for complex defects and outflow tract obstruction and decreased risk for ventricular septal defects. These different risk profiles of type 1 diabetes and overweight and obesity may suggest distinct underlying teratogenic mechanisms.  Authors: Riitta Turunen, M.D., Ph.D., and Emmi Helle, M.D., ...

A study carried out by CNRS1 scientists working with an international team has revealed that around 70 million years ago, when dinosaurs existed, the ancestors of primates most commonly lived in pairs. Only 15% of them opted for a solitary lifestyle. This discovery — that our ancestors adopted variable forms of social organization — challenges the hitherto commonly accepted hypothesis that at the time of dinosaurs, the ancestors of primates lived alone, and that pair living evolved much later. Most likely, pair living offered significant benefits, such as easier reproduction and reduced costs of thermoregulation by huddling in pairs. While several studies have already been conducted ...

What are the clouds of Venus made of? Scientists know it’s mainly made of sulfuric acid droplets, with some water, chlorine, and iron. Their concentrations vary with height in the thick and hostile Venusian atmosphere. But until now they have been unable to identify the missing component that would explain the clouds’ patches and streaks, only visible in the UV range. In a new study published in Science Advances, researchers from the University of Cambridge synthesised iron-bearing sulfate minerals that are stable under the harsh chemical conditions in the Venusian clouds. Spectroscopic analysis revealed that a combination of two minerals, rhomboclase and acid ferric ...

Air pollution significantly impacts human health, with Hainan Province in China aiming to achieve world-leading ambient air quality by 2035, despite already having relatively good air quality in China. The existing Ambient Air Quality Standards (AAQS) offer insufficient guidance for further enhancing air quality in Hainan, which stands at the forefront of China's environmental protection efforts. Consequently, it is imperative to develop Hainan's local AAQS. This initiative, responding to WHO's strengthened guidelines, aims to address unique regional challenges in air quality ...

The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fibreglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. This was revealed by a study, published on 3 January 2024 in the journal Nature Nanotechnology, conducted on glass nanofibers by a French-Chinese team including a CNRS chemist.1 The reason for this is the inability of the macrophages2 naturally present in pulmonary alveolar tissue to eliminate foreign bodies that are too large. The study was initially conducted in vitro with electrochemical nanosensors, and revealed that when confronted ...

In a recent tragic incident, approximately 100 elephants in Africa perished due to inadequate access to water. The United Nations Environment Programme (UNEP) issues a warning that around 2.5 billion people worldwide could face water scarcity by 2025. In the face of water shortages affecting not only human society but also the entire ecological community due to the climate crisis, it becomes crucial to adopt comprehensive measures for managing water quality and quantity to avert such pressing challenges.   A research team led by Professor Jonghun Kam and PhD candidate Kwang-Hun Lee from the Division of Environmental Science and ...

The recent cold spell has plunged the nation into a deep freeze, resulting in the closure of 247 national parks, the cancellation of 14 domestic flights, and the scrapping of 107 cruise ship voyages. While the cold snap brought relief by significantly reducing the prevalence of particulate matter obscuring our surroundings, a recent study indicates that, besides diminishing particulate matter, it is significantly contributing to the heightened uptake of carbon dioxide by the East Sea.   According to research conducted by a team of researchers ...

As concerns over the world’s declining bird population mount, animal ecologists developed an analytical approach to better understand one of the latest threats to feathered creatures: the rise of wind and solar energy facilities. “Bird mortality has become an unintended consequence of renewable energy development,” said Hannah Vander Zanden, an assistant professor of biology at the University of Florida. “If we want to minimize or even offset these fatalities, especially for vulnerable populations, we need to identify the geographic origin of affected birds. In other words, are the dead birds local or are they coming ...

Spintronic devices are electronic devices that utilize the spin of electrons (an intrinsic form of angular momentum possessed by the electron) to achieve high-speed processing and low-cost data storage. In this regard, spin-transfer torque is a key phenomenon that enables ultrafast and low-power spintronic devices. Recently, however, spin-orbit torque (SOT) has emerged as a promising alternative to spin-transfer torque. Many studies have investigated the origin of SOT, showing that in non-magnetic materials, a phenomenon called the spin Hall effect (SHE) is key to achieving SOT. In these materials, the existence of a “Dirac band” ...

A bit of weed before a workout can boost motivation and make exercise more enjoyable. But if performance is the goal, it may be best to skip that joint. That’s the takeaway of the first ever study to examine how legal, commercially available cannabis shapes how exercise feels. The study of 42 runners, published Dec. 26 in the journal Sports Medicine, comes almost exactly 10 years after Colorado became the first state to commence legal sales of recreational marijuana, at a time when cannabis-users increasingly report mixing it with workouts. “The bottom-line finding is that cannabis before exercise seems ...

For military veterans, many of the deepest wounds of war are invisible: Traumatic brain injuries resulting from head trauma or blast explosions are a leading cause of post-traumatic stress disorder, anxiety, depression and suicide among veterans. Few treatments have been effective at diminishing the long-term effects of TBI, leaving many veterans feeling hopeless.  Now, Stanford researchers have discovered that the plant-based psychoactive drug ibogaine, when combined with magnesium to protect the heart, safely and effectively reduces PTSD, anxiety and depression and improves functioning in veterans with TBI. Their new study, to be published ...

Ikoma, Japan – Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. It is marked by lung damage that is lasting and incurable, leaving lung transplantation as the only viable treatment option. Unfortunately, finding suitable lung donors is difficult. To compensate for this shortage of donors, regenerative medicine is making strides in developing lungs from pluripotent stem cells (PSCs), using interspecies animal models. Through a biological technique known as blastocyst complementation, PSCs, and embryonic ...

A new study led by researchers from the University of Helsinki, along with colleagues at the Massachusetts General Hospital and Broad Institute of Harvard and MIT, provides significant breakthroughs in our understanding of the genetics behind gestational diabetes. Gestational diabetes is a common pregnancy disorder annually affecting more than 16 million pregnancies worldwide, with substantial health implications for both mothers and their children. It is characterised by elevated blood sugar levels in pregnant women who did not have diabetes before becoming pregnant. Despite the fact that gestational diabetes constitutes a major global health problem, there is remarkably ...
