NIST team builds hybrid quantum system by entangling molecule with atom

Physicists at the National Institute of Standards and Technology (NIST) have boosted their control of the fundamental properties of molecules at the quantum level by linking or 'entangling' an electrically charged atom and an electrically charged molecule, showcasing a way to build hybrid quantum information systems that could manipulate, store and transmit different forms of data.

Noninvasive brain stimulation with ultrasonic waves controls monkeys' choices

Noninvasive pulses of ultrasound waves aimed at specific regions in the brains of macaque monkeys can give some control over the monkeys' choices, scientists report. These findings indicate that ultrasonic brain stimulation could provide a noninvasive, drug-free avenue to study and potentially treat decision-making disorders such as addiction.

Oldest connection with Native Americans identified near Lake Baikal in Siberia

Using human population genetics, ancient pathogen genomics and isotope analysis, a team of researchers assessed the population history of the Lake Baikal region, finding the deepest con-nection to date between the peoples of Siberia and the Americas. The current study, published in the journal Cell, also demonstrates human mobility, and hence connectivity, across Eurasia during the Early Bronze...

Overcoming challenges of individuals with autism during the COVID-19 pandemic

Dr. Adrien Eshraghi and Miller School coauthors published a new correspondence titled COVID-19: overcoming the challenges faced by individuals with autism and their families in The Lancet Psychiatry. In this commentary, the authors address specific challenges patients with autism and their families might encounter during the pandemic, as well as what healthcare providers should know and do to...

Potentially treatable genetic mutations revealed in subset of prostate cancer patients

Prostate cancer patients resistant to PSMA-targeted therapy often have potentially treatable mutations in their DNA damage-repair genes, according to research published in the May issue of The Journal of Nuclear Medicine. In an exploratory study using a relatively new technique--targeted next-generation gene sequencing--researchers found mutations in six out of seven patients with metastatic...

Primary care physicians experience more burnout and anxiety than other health professions

Health care professionals experience high rates of anxiety and burnout, a growing public health concern, particularly in light of projected physician shortages and the COVID-19 pandemic. New research led by Dr. Debora Goldberg of George Mason University's College of Health and Human Services before the COVID-19 pandemic found that primary care physicians reported burnout at twice the rate of other...

Quantum leap: Photon discovery is a major step toward at-scale quantum technologies

A team of physicists at the University of Bristol has developed the first integrated photon source with the potential to deliver large-scale quantum photonics. The development of quantum technologies promises to have a profound impact across science, engineering and society. Quantum computers at scale will be able to solve problems intractable on even the most powerful current supercomputers, with...

Release of a new soil moisture product (2002-2011) for mainland China

A gridded soil moisture product for mainland China from 2002 to 2011 was released in a recent paper in 'Science China Earth Sciences'. This new dataset, which was generated by assimilating passive microwave satellite data, is proven to outperform existing remote sensing products and expected to better support regional climate and eco-hydrological studies.

Researchers may have uncovered the Achilles heel of viruses

A new research study headed by the Department of Biomedicine at Aarhus University, Denmark, identifies how viruses avoid the body's immune system and cause infections and diseases. The new knowledge could pave the way for the treatment of viral diseases such as COVID-19.

Scientists find a new way to reverse symptoms of Fragile X

MIT scientists have identified a potential new strategy for treating Fragile X syndrome, a disorder that is the leading heritable cause of intellectual disability and autism. In a study of mice, the researchers showed that inhibiting an enzyme called GSK3 alpha reversed many of the behavioral and cellular features of Fragile X.

Scientists find out which of the metazoans has the smallest known genome

Researchers at St Petersburg University have deciphered the Intoshia variabili gene, the smallest representative of the parasite from the Orthonectida group. At present, its genome is proved to be smallest among all metazoans and includes only 5,120 genes. Phylogenetic relationships of Orthonectida have remained controversial for a long time. According to recent data from St Petersburg University...

Should tomatoes go in the fridge?

There is much debate about the correct storage of tomatoes. Should tomatoes be in the fridge or kept at room temperature? Researchers from the University of Göttingen investigated whether there are differences in the flavour of ripe tomatoes depending on how they are stored, taking into account the chain of harvesting from farm to fork. No difference was found: the variety of tomato is much...

Spring rains are a surprising source of pollen

Spring rains washes away some pollen, but not all. University of Iowa researchers have found tree pollen fragments can remain airborne for hours after a storm. The tiny pollen particles can exacerbate allergies because they can reach deep in the lungs.
