Study of material surrounding distant stars shows Earth's ingredients 'pretty normal'

The Earth’s building blocks seem to be built from ‘pretty normal’ ingredients, according to researchers working with the world’s most powerful telescopes. Scientists have measured the compositions of 18 different planetary systems from up to 456 light years away and compared them to ours, and found that many elements are present in similar proportions to those found on Earth. This will have implications for finding Earth-like bodies elsewhere.

Amish nemaline myopathy natural history study finds promise for gene therapy treatment

A new comprehensive natural history study about Amish nemaline myopathy (ANM) in the Old Order Amish population focuses on the promise of gene therapy for this lethal disorder. Amish nemaline myopathy (ANM) is an infantile-onset muscle disease linked to a mutation of the TNNT1 gene. The study summarizes genealogical records, clinical data, and molecular reports of one hundred and six ANM patients born between 1923 and 2017.

New study finds fake, low-quality medicines prevalent in the developing world

A new study found that substandard and falsified medicines, including medicines to treat malaria, are a serious problem in much of the world. In low- and middle-income countries, more than 13 percent of the essential medicines that satisfy the priority health care needs of the population fall in this category. When looking specifically at African countries, the portion of substandard and falsified medicines rises to almost 19 percent.

New study views cancer treatment as a game to find strategies that improve patient outcomes

Game theory can be utilized to identify potential flaws in current cancer treatment approaches and suggest new strategies to improve outcomes in patients with metastatic cancer, according to a new article. The study challenges the decades old standard of treatment for metastatic cancers in which drugs are typically administered continuously at the maximum-tolerated dose (MTD) until the tumor progresses.

Exercising for 90 minutes or more could make mental health worse, study suggests 

Exercising for 90 minutes or more could make mental health worse, study suggests Exercising for 90 minutes a day or more could make mental health worse, a major new research suggests. In the largest study of its kind researchers at Yale University and Oxford looked at the fitness regimes of 1.2 million people and compared them with how often they felt depressed or stressed. People who did no extra physical activity said they felt low an average of 3.4 days of the month, while those who exercised regularly reported just two days, a reduction of 43 per cent. However the researchers discovered that more exercise was not always better, with 45 minutes three to five times a week found to have the biggest benefits. People who exercised for periods of 90 minutes at a time suffered up to one day extra of poor mental health each month compared to those who stuck to 45 minute sessions. “Previously, people have believed that the more exercise you do, the better your mental health, but our study suggests that this is not the case,” said Dr Adam Chekroud, Assistant Professor of Psychiatry at Yale University. “Doing exercise more than 23 times a month, or exercising for longer than 90 minute sessions is associated with worse mental health. “It’s difficult to speculate what is driving the effect. It is easy to imagine why someone might have poor mental health if they are exercising more 6 or 7 days per week. They could be getting run down (physically exhausted) or burned out (mentally), both of which might make them feel stressed or depleted.” Exercise is known to reduce the risk of cardiovascular disease, stroke, diabetes, and early death from all causes, but its association with mental health is not so clear.  The study included all types of physical activity, ranging from childcare, housework, lawn-mowing and fishing to cycling, going to the gym, running and skiing. All types of exercise were associated with improved mental health, but the strongest benefits were seen for team sports, cycling, aerobic and gym exercise which saw a reduction in poor mental health days of 22.3 per cent, 21.6 per cent, and 20.1 per cent, respectively. Even completing household chores was associated with an improvement of around 10 per cent, or around half a day less depression or stress each month. People who exercised regularly had on average two fewer days of poor mental health each month Credit:  Courtney Keating Commenting on the study, which was published in The Lancet Psychiatry, Prof Stephen Lawrie, Head of Psychiatry at the University of Edinburgh, said: “I would summarise the results as indicating that activity, is good for mental health – but that one can do too much. Every second day for 45-60 mins might be optimal.   “Certainly, the results suggest that exercising every day is associated with worse mental health.  I suspect we all know people who seem ‘addicted’ to exercise and if this starts to impact on other aspects of life – like foregoing social activities because one has to be up at the crack of dawn to run several miles – it might actually be bad for people.” Dr Brendon Stubbs, NIHR Clinical Lecturer, King’s College London’s Institute of Psychiatry, added:” The message reinforces government guidelines which recommend people should seek to achieve over 150 minutes of physical activity per week, which could include 30 minutes 5 times a week.   “The good news is that lots of different types of physical activity appear to be associated with better mental health. Thus, the key message from this paper and the wider literature is that people should find a physical activity they enjoy and try and do it regularly but just getting started is key.”

Study illuminates genes behind beautiful 'glow' of Bermuda fireworms

A new study looks at the genes behind an incredible, luminous seasonal mating display produced by swarms of bioluminescent marine Bermuda fireworms. The new research confirms that the enzymes responsible for the fireworms’ glow are unique among bioluminescent animals and entirely unlike those seen in fireflies. The study also examines genes associated with some of the dramatic — and reversible — changes that happen to the fireworms during reproduction.

Unwise opioids for wisdom teeth: Study shows link to long-term use in teens and young adults

Getting wisdom teeth removed may be a rite of passage for many teens and young adults, but the opioid painkiller prescriptions that many receive could set them on a path to long-term opioid use, a new study finds. Young people ages 13 to 30 who filled an opioid prescription immediately before or after they had their wisdom teeth out were nearly 2.7 times as likely as peers to still be filling opioid prescriptions months later.
