Making a difference: Efficient water harvesting from air possible

Harvesting water from the air and decreasing humidity are crucial to realizing a more comfortable life for humanity. Water-adsorption polymers have been playing a key part in atmospheric water harvesting and desiccant air conditioning, but desorption so that the polymers can be efficiently reused has been an issue. Now, Osaka Metropolitan University researchers have found a way to make desorption of these polymers more efficient. Usually, heat of around 100°C is required to desorb these polymers, but Graduate School of Engineering student Daisuke Ikegawa, Assistant Professor Arisa Fukatsu, ...

World’s most common heart valve disease linked to insulin resistance in large national study

A large new population study of men over 45 indicates insulin resistance may be an important risk factor for the development of the world’s most common heart valve disease – aortic stenosis (AS). Published today in the peer-reviewed journal Annals of Medicine, the findings are believed to be the first to highlight this previously unrecognised risk factor for the disease. It is hoped that by demonstrating this link between AS and insulin resistance – when cells fail to respond effectively to insulin and the body makes more than necessary to maintain normal glucose ...

Study unravels another piece of the puzzle in how cancer cells may be targeted by the immune system

Effective immunity hinges on the ability to sense infection and cellular transformation. In humans, there is a specialised molecule on the surface of cells termed MR1. MR1 allows sensing of certain small molecule metabolites derived from cellular and microbial sources; however, the breadth of metabolite sensing is unclear. Published in PNAS, researchers at the Monash University Biomedicine Discovery Institute have identified a form of Vitamin B6 bound to MR1 as a means of engaging tumour-reactive immune cells. The work involved an international collaborative team co-led by researchers from the University of Melbourne. According ...

Long-sought structure of powerful anticancer natural product solved by integrated approach

A collaborative effort by the research groups of Professor Haruhiko Fuwa from Chuo University and Professor Masashi Tsuda from Kochi University has culminated in the structure elucidation and total synthesis of anticancer marine natural products, iriomoteolide-1a and -1b. These natural products were originally isolated from the marine dinoflagellate collected off the Iriomote Island, Okinawa, Japan. Because of its potent anticancer activity, iriomoteolide-1a is an intriguing natural product that attract immense attention from the chemical community around the globe. ...

World’s oldest lizard wins fossil fight

A storeroom specimen that changed the origins of modern lizards by millions of years has had its identity confirmed. The tiny skeleton, unearthed from Triassic-aged rocks in a quarry near Bristol, is at least 205 million years old and the oldest modern-type lizard on record. Recently, the University of Bristol team’s findings came under question, but fresh analysis, published today in Royal Society Open Science, proves that the fossil is related to modern anguimorphs such as anguids and monitors. The discovery ...

Simple secret to living a longer life

If everyone in the United States population was as active as the top 25 per cent, individuals over the age of 40 could add five years to their life, according to a new study led by Griffith University researchers. Physical activity has long been known to be good for health, however estimates have varied regarding how much benefit could be gained from a defined amount of activity, both for individuals and for populations. This latest study used accelerometry to gain an accurate view of the population’s physical activity levels instead of relying on survey responses as per other studies, and found the benefits were around twice as strong ...

Same plant, different tactic: Habitat determines response to climate

Plants need light to grow, but too much light can induce damage to the photosynthetic complex known as photosystem II. It is known that plants adapted to growing under full sun repair this light-induced damage more. But this repair activity slows down in colder temperatures. An Osaka Metropolitan University-led international research team has now found some clues to how plants survive in colder regions. Graduate School of Science Associate Professor Riichi Oguchi and colleagues from Australia, Austria, and Japan grew Arabidopsis thaliana (commonly ...

Drinking plenty of water may actually be good for you

Public health recommendations generally suggest drinking eight cups of water a day. And many people just assume it’s healthy to drink plenty of water. Now researchers at UC San Francisco have taken a systematic look at the available evidence. They concluded that drinking enough water can help with weight loss and prevent kidney stones, as well as migraines, urinary tract infections and low blood pressure. “For such a ubiquitous and simple intervention, the evidence hasn’t been clear and the benefits were not well-established, so we wanted to take a closer look,” said senior and corresponding author Benjamin Breyer, MD, MAS, the Taube ...

Men at high risk of cardiovascular disease face brain health decline 10 years earlier than women

Men with cardiovascular disease risk factors, including obesity, face brain health decline a decade earlier—from their mid 50s to mid 70s—than similarly affected women who are most susceptible from their mid 60s to mid 70s, suggest the findings of a long term study, published online in the Journal of Neurology Neurosurgery & Psychiatry. The most vulnerable regions of the brain are those involved in processing auditory information, aspects of visual perception, emotional processing and memory, with ...

Irregular sleep-wake cycle linked to heightened risk of major cardiovascular events

An irregular sleep-wake cycle is associated with a heightened risk of major cardiovascular events, such as heart attack and stroke, even for those who clock up the recommended nightly hours of shut-eye, finds research published online in the Journal of Epidemiology & Community Health. Most studies looking at the impact of sleep on health have focused on sleep length and less is known about the impact of sleep patterns, in particular the impact of irregular sleep—defined as variations in the time a person goes to sleep and wakes up. To explore this further, the researchers drew on 72,269 people aged 40 to 79, taking part in the UK ...

Depression can cause period pain, new study suggests

Women are twice as likely as men to suffer from depression and often experience more severe physical symptoms. This gender difference is particularly evident during reproductive years and dramatically impacts the lives of hundreds of millions of people worldwide. However, although links between mental health and reproductive health have been found, the associations have remained underexplored. In a new study published in Briefings in Bioinformatics, researchers from China and the UK have found that depression can increase the chances of a person experiencing menstrual pain (dysmenorrhea).

Congenital heart defects caused by problems with placenta

Congenital heart defects are the most common form of human birth defect, but we still don’t fully understand what causes them. Previous research had suggested that some heart defects could be triggered by problems with the placenta, the organ that provides oxygen and nutrients to the developing embryo. Now, researchers at Nanjing University, China have confirmed this link by focusing on a protein whose levels are reduced in many patients with congenital heart defects, called SLC25A1. SLC25A1 plays a key role in transporting ...
