Is forest harvesting increasing in Europe?

Apr 28 2021 - 00:04
Is forest harvesting increasing in Europe? Yes, but not as much as reported last July in a controversial study published in Nature.Forest harvest has increased by just 6% in recent years, not 69% as reported by the European Commission's Joint Research Centre. The errors are due to satellite sensitivity and natural disturbances according to a response paper authored by 30 scientists from 13 European countries.

Draining brain's debris enhances Alzheimer's therapies in mice

Apr 28 2021 - 00:04
Researchers at Washington University School of Medicine in St. Louis have found that improving the function of the brain's drainage network, known as the meningeal lymphatics, can make certain experimental Alzheimer's therapies more effective in mice.

Childhood air pollution exposure linked to poor mental health at age 18

Apr 28 2021 - 00:04
Childhood exposure to air pollution, such as nitrogen oxides and fine particulate matter, is a risk factor for mental illness at age 18. It is less of a factor than family history, but equal to lead. The finding comes from a cohort of 2,000 twins born in England and Wales in 1994-1995 and followed to young adulthood.

UChicago scientists harness molecules into single quantum state

Apr 28 2021 - 00:04
Being able to build and control systems of quantum particles, which are among the smallest objects in the universe, is the key to developing quantum technology. That goal is now a step closer thanks to University of Chicago scientist Cheng Chin, who just figured out how to bring multiple molecules at once into a single quantum state--one of the most important goals in quantum physics.

Researchers identify a psychedelic-like drug without the hallucinogenic side effects

Apr 28 2021 - 00:04
Psychedelic drugs have shown promise for treating neuropsychiatric disorders like depression and posttraumatic stress disorder. However, due to their hallucinatory side effects, some researchers are trying to identify drugs that could offer the benefits of psychedelics without causing hallucinations. In the journal Cell on April 28, researchers report they have identified one such drug through the development of a genetically encoded fluorescent sensor--called psychLight--that can screen for hallucinogenic potential.

Stress slows the immune response in sick mice

Apr 28 2021 - 00:04
The neurotransmitter noradrenaline, which plays a key role in the fight-or-flight stress response, impairs immune responses by inhibiting the movements of various white blood cells in different tissues, researchers report April 28th in the journal Immunity. The fast and transient effect occurred in mice with infections and cancer, but for now, it's unclear whether the findings generalize to humans with various health conditions.

Researchers develop comprehensive pregnancy care management plan among Chinese pregnant women type 1 diabetes

Apr 28 2021 - 00:04
The research team led by Prof. WENG Jianping from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has implemented a comprehensive preconception-to-pregnancy management plan, namely CARNATION study, for women with type 1 diabetes (T1D), to reduce the risks of adverse pregnancy outcomes and improve the pregnancy care since 2015. The study was published in Diabetes Care.

Brazilian coronavirus variant likely to be more transmissible and able to evade immunity

Apr 28 2021 - 00:04
A new study with the University of Copenhagen represented indicates that the coronavirus variant called P.1, which originated in Brazil, could pose a bigger threat than previously assumed. The researchers conclude that it is likely that P.1 is more transmissible than other strains of SARS-Cov2 and that might be able to evade immunity gained from previous infection with coronavirus.

New model may explain the mystery of asymmetry in Parkinson's disease

Apr 28 2021 - 00:04
Parkinson's disease (PD) is characterized by slowness of movement and tremors, which often appear asymmetrically in patients. The new model of PD described in this review article published in the Journal of Parkinson's Disease may explain these perplexing asymmetrical motor symptoms and other known variations such as different degrees of constipation and sleep disorders.

Job changes following breast cancer are frequent in some cases

Apr 28 2021 - 00:04
Breast cancer diagnosis: 88 percent of patients survive the dangerous disease in the first five years. Work is important for getting back to normality. Researchers from the University of Bonn and the German Cancer Society investigated how satisfied former patients are with their occupational development over a period of five to six years. About half experienced at least one job change during the study period. Around ten percent of those affected even report involuntary changes.

Socioeconomic deprivation modifies genetic influence on higher education

Apr 28 2021 - 00:04
A comprehensive study from Uppsala University demonstrates that socioeconomic deprivation modifies genetic effects on higher education and abstract reasoning. The paper illustrates how genes play a greater role in educational attainment in more socioeconomically deprived regions of the United Kingdom. The study was recently published in the American Journal of Psychiatry.
