Probiotics may help treat acne

A recent analysis published in Dermatologic Therapy suggests that probiotics may be an effective alternative to traditional treatments for acne. The study found that probiotics can reduce inflammation and help the skin's natural defenses against acne, but further research is needed to confirm these findings.

Online education platforms could scale high-quality STEM education for universities

A multi-site study found that online and blended instruction produced similar learning outcomes to traditional in-person classes, with students scoring higher on course assignments but reporting slightly lower satisfaction. The study also showed significant cost savings, with blended instruction lowering costs by 15-19% and fully onlin...

The Lancet Gasteroenterology & Hepatology: First clinical trial finds probiotic treatment with dead bacteria is better than placebo at alleviating symptoms of irritable bowel syndrome

A new 12-week clinical trial found that heat-inactivated Bifidobacterium bifidum MIMBb75 improved IBS symptoms by at least 30% in 34% of patients compared to 19% on placebo. The treatment was also associated with a strong placebo effect, but the dead bacterial cells were still significantly better than placebo.

Cancer mutation in dual role

Researchers at the University of Freiburg have discovered that cancer-causing mutations in the KRAS gene lead to inflammation and slow down tumor growth. The study, led by Prof. Dr. Robert Zeiser, shows that K-Ras plays a dual role in both cancer development and immune response.

Amazonian crops domesticated 10,000 years ago

Researchers confirm early plant cultivation in southwestern Amazonia, dating back to 10,350 years ago, with evidence of manioc and squash. The discovery suggests that the earliest inhabitants were not just hunter-gatherers but also engaged in plant cultivation.

Putting remdesivir to the test for COVID-19

Scientists are closely monitoring remdesivir trials for COVID-19 treatment, despite caution from infectious disease experts about difficult-to-interpret results. The antiviral drug blocks RNA polymerase used by SARS-CoV-2 to replicate, showing promise in lab experiments and animal studies.

Knowledge of cancer diagnosis may affect survival

Patients with lung cancer in China who knew their diagnosis survived longer than those who did not, with a median survival time of 18.33 months versus 8.77 months. The study suggests that full disclosure of cancer diagnoses can benefit patients in the long term with proper communication and support.

A bad egg does good for its mother

Researchers at Northwestern University found that a damaged fertilized egg sends a molecular signal to the mother that protects her from cellular stress and environmental damage. This allows the mother to live longer and produce healthier eggs.

Rice chemist wins grant to simplify drug design

László Kürti, a Rice University chemist, has received a prestigious grant to speed up drug design by simplifying the synthesis of essential precursors. The five-year grant will support research into amines and their derivatives, which are present in most drug molecules. This could lead to more environmentally friendly drug development.

Is autoimmunity on the rise?

A study published in Arthritis & Rheumatology found a significant increase in autoimmunity prevalence in the US population between 1988 and 2012. The prevalence of antinuclear antibodies (ANA) rose from 11.0% in 1988 to 15.9% in 2011-2012, affecting an estimated 41 million individuals.

The Lancet: Modelling study estimates impact of relaxing control measures on possible second wave of COVID-19 in China

A modelling study suggests that relaxing control measures in regions outside Hubei province could lead to a second wave of COVID-19 infection, with cases potentially exceeding 1 and resulting in higher health and economic loss. The study advises policymakers to fine-tune control measures using real-time monitoring of transmissibility a...

X-ray vision through the water window

Researchers at ETH Zurich have developed a high-repetition-rate laser source producing coherent soft x-rays spanning the entire 'water window', enabling new applications in chemistry and biology. The system, capable of 100 kHz repetition rates, demonstrates a significant improvement over existing sources.

The effects of inflammatory bowel disease on pregnancy

Women with IBD had higher rates of Caesarean section and intrauterine growth retardation compared to those without IBD. Those with mild Crohn's disease did as well during pregnancy as women without IBD, but those with more severe disease experienced increased miscarriage and low birth weight.

Extreme action costs popular support for protest movements, new study finds

A new study found that social movements lose popular approval when action is disruptive. Researchers conducted six experiments to understand the 'activist's dilemma' and how movements can overcome it. The findings suggest that activists should weigh their options carefully to achieve their objectives.
