No peers, no beers: Research shows youth substance use declined during the COVID-19 pandemic

Posted: 15 Jun 2022 10:08 AM PDT

With stay-at-home orders during the COVID-19 pandemic, youth spent more time at home with family and were more isolated from in-person interaction with peers. Largely due to this social isolation from peers, substance use among youth declined, according to researchers.

New perspective on RNA function: RNA regulates proteins and thereby can control cell growth, study shows

Posted: 15 Jun 2022 10:08 AM PDT

Scientists gained new insights into RNA-mediated regulation of proteins (riboregulation) and its role in controlling cell growth, and most importantly how undifferentiated cells (embryonic stem cells) transform into specialised cells (e.g., liver cells). They discovered this while studying how mRNA molecules bind to and regulate ENO1, an enzyme involved in glucose metabolism. This contrasts to most previous studies, which focused on how proteins regulate RNA, this one shows that an RNA regulates a protein. This new perspective on riboregulation may represent a more widespread and meaningful principle of biological control.

Androgen receptor signaling contributes to targeted therapy resistance in melanoma

Posted: 15 Jun 2022 08:32 AM PDT

Androgen receptor (AR) signaling affects response to BRAF/MEK inhibitor therapy in both males and females with melanoma, researchers have shown. The findings provide a new target to combat therapeutic resistance and one possible answer to why men face a poorer prognosis than women when diagnosed with melanoma.

Sampling surfaces for COVID-19 virus at public health laboratories

A new study shows that the methodology used to detect the COVID-19 virus in nasal swabs at public health clinics can be used to detect the virus on surfaces in indoor settings such as schools.

Preadolescents exposed to high levels of air pollution in their first years of life display changes in brain connectivity

Posted: 15 Jun 2022 08:32 AM PDT

Higher exposure to air pollution is associated with higher functional brain connectivity among several brain regions in preadolescents, while exposure to traffic noise was not, according to a study. The findings also identify the first years of life as the most sensitive period of exposure to air pollution.

Opioid use disorder: Flexible treatment at home proves effective

Posted: 15 Jun 2022 08:32 AM PDT

Initial results of the Canadian OPTIMA study comparing the efficacy of two models of care for treating opioid use disorder have been completed.

Origins of the Black Death identified

Posted: 15 Jun 2022 08:32 AM PDT

The Black Death, the biggest pandemic of our history, was caused by the bacterium Yersinia pestis and lasted in Europe between the years 1346 and 1353. Despite the pandemic's immense demographic and societal impacts, its origins have long been elusive. Now, scientists have obtained and studied ancient Y. pestis genomes that trace the pandemic's origins to Central Asia.

Previously hidden protoclusters could reveal new details of galaxy evolution

Posted: 15 Jun 2022 08:32 AM PDT

The ancestors of some of the largest galaxy clusters have been hiding in plain sight. New work demonstrates a new technique for identifying the precursors of the most extreme galactic environments.

Tumor 'signatures' could provide key to more accurate treatment for deadliest cancers

Posted: 15 Jun 2022 08:32 AM PDT

Scientists have found a way to identify and interpret 'signatures' that reveal the complex genetic causes of some of the deadliest cancers -- which often have a survival rate of less than 10%. The results could allow them to develop more accurate treatments and significantly improve survival rates.

What quantum information and snowflakes have in common, and what we can do about it

Posted: 15 Jun 2022 08:32 AM PDT

Qubits, the basic building blocks of quantum computers, are as fragile as snowflakes. Now, researchers have come up with a new way of reading out the information from certain kinds of qubits without destroying them in the process, potentially paving the way for a quantum internet.

New material paves the way for remote-controlled medication and electronic pills

Posted: 15 Jun 2022 07:29 AM PDT

Biomedicines are produced by living cells and are used to treat cancer and autoimmune diseases among other things. One challenge is that the medicines are very expensive to produce, something that limits global access. Now researchers have invented a material that uses electrical signals to capture and release biomolecules. The new and efficient method may have a major impact in the development of biomedicines and pave the way for the development of electronic pills and drug implants.

Cancer clinical trials bounce back after significant COVID-19 disruption: Data from two large US cancer centers

Posted: 15 Jun 2022 07:29 AM PDT

Data from two large cancer centres in the United States have shown that the COVID-19 pandemic caused substantial disruption to clinical trials for cancer treatment and care. After a 46% decrease in new patient accruals, and a 24% decrease in newly activated trials between March and May 2020, a bounceback was seen in 2021. The findings suggest ways of improving the running of clinical trials and improving patients access to them worldwide.

Cholesterol-lowering gene changes may increase the risk of cataracts

Posted: 15 Jun 2022 07:29 AM PDT

Researchers used large-scale genotyping and exome sequencing from the UK Biobank to gain insight into the expected effects of long-term statin use on cataract risk. The analysis found that common genetic variants in more than 402,000 people, who were not taking statins, that mimic the effects of LDL-cholesterol lowering statins are associated with a higher risk of cataracts and cataract surgery. They also found that rare genetic mutations in 169,172 people, mimicking statin treatment, increased the risk of developing cataracts by nearly five times.
