Temporary increase in dopamine levels initiates sleep state transitions

Historically, the neurological mechanisms underlying sleep-cycle generation have been elusive. But now, researchers from Japan have uncovered new information about how the brain transitions from one sleep state to another.

Malaria drug could help treat chemotherapy-resistant head and neck cancers

A new study suggests that the malaria drug hydroxychloroquine inhibits pathways that drive resistance to the chemotherapy agent cisplatin in head and neck cancers and restores tumor-killing effects of cisplatin in animal models.

Exposure to room lighting during sleep can impair glucose and cardiovascular regulation

Close the blinds, draw the curtains and turn off all the lights before bed: Exposure to even moderate ambient lighting during nighttime sleep, compared to sleeping in a dimly lit room, harms your cardiovascular function during sleep and increases your insulin resistance the following morning, reports a new Northwestern Medicine study published in PNAS.

Tumor cells’ 'ferroaddiction' can be exploited to deliver powerful anticancer drugs

Researchers at the University of California, San Francisco, have discovered that cells carrying the most common mutation found in human cancer accumulate large amounts of ferrous iron and that this "ferroaddiction" can be exploited to specifically deliver powerful anticancer drugs without harming normal, healthy cells.

Damage to the inner ear system linked to fall risk among Alzheimer’s patients

A Johns Hopkins Medicine study of about 50 people with Alzheimer's disease has added to evidence that damage to the inner ear system that controls balance is a major factor in patients' well-documented higher risk of falling.

Interdisciplinary researchers team up on $15 million NSF grant to establish an institute in ‘imageomics’

Researchers in three different disciplines at Virginia Tech are partnering in a $15 million grant from the National Science Foundation to establish an institute in the new field of "imageomics," aimed at creating a new frontier of biological information using vast stores of existing image data, such as publicly funded digital collections from national centers, field stations, museums, and individual laboratories.

Illinois Tech receives $2.17 million NIH grant to develop drug treatments for cholera

Illinois Institute of Technology is receiving a four-year grant from the National Institutes of Health to fund research to develop drug treatments for cholera and other multi-drug-resistant strains of disease-causing bacteria.

Intersectional, anterograde transsynaptic targeting system used to reveal two different brain circuits

Osaka Metropolitan University uses new “intersectional, anterograde transsynaptic targeting system” to reveal two different mouse brain circuits: the retina/primary visual cortex to the superior colliculus and the bilateral motor cortex to the dorsal striatum.

Study explores immune escape mutations caused by prolonged viral shedding in immunocompromised COVID-19 patient

A new study examined a unique case of extended viral shedding in an immunocompromised patient that produced a series of SARS-CoV-2 immune escape mutations over a seven-month period.

How have human organoids been used in research to study SARS-CoV-2?

In a recent review published in the journal Organoids, scientists have presented an overview on the use of human stem cell-derived organoids in understanding functionality and cellular tropism of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), a deadly beta-coronavirus responsible for the ongoing coronavirus disease 2019 (COVID-19) pandemic.

Study identifies two types of brain cells involved in organizing discrete memories

Researchers have identified two types of cells in our brains that are involved in organizing discrete memories based on when they occurred.

Community-based approach to genetic testing may have beneficial effects, study finds

In 2010, scientists discovered that African Americans who are born with certain variants of a gene called apolipoprotein L1 (APOL1) have a higher-than-average risk for experiencing chronic kidney disease (CKD).

Increased levels of dopamine play an important role in transition to REM sleep, mice study suggests

What triggers the mammalian sleep cycle's shift between non-rapid eye movement (NREM) and rapid eye movement (REM) sleep? A new study in mice suggests increased levels of dopamine in a key region of the brain during NREM sleep play an important role in this transition.

Discovery provides a more precise picture of the retina's optical properties

Researchers at the National Eye Institute (NEI) have discovered that power-producing organelles in the eye's photoreceptor cells, called mitochondria, function as microlenses that help channel light to these cells' outer segments where it's converted into nerve signals.

Covid expert joins exodus into business, where science parlays into profits

Millions of free covid-19 rapid tests arriving in Americans' mailboxes are long-awaited vindication for Dr. Michael Mina, who, as a Harvard assistant professor, had been advocating for two years that the best way to limit covid is to identify it quickly, cheaply, and widely with rapid antigen tests so infected people know to isolate themselves.

To be one in a million: ‘Who thinks it’s going to be you?’

Monica Melkonian wanted the Johnson & Johnson covid vaccine. It was only one shot and then she would be protected against the virus. So she was thrilled when the vaccination clinic at the Deschutes County Fair & Expo Center on April 7 had her first choice.

A ubiquitous protein may be key to the survival of neurons most impacted by glaucoma

A ubiquitous protein called sigma 1 receptor, which is known to protect cells from stress, appears key to the function and survival of the neurons most impacted by glaucoma, scientists report.

J&J-vaxxed, mRNA-boosted, and pondering a third shot

Yes, we are all exhausted by the covid pandemic. Flummoxed by the constantly shifting science and guidelines. Worried about a succession of scary new variants, each with its own name, like hurricanes.

Study identifies olfactory dysfunction as an early symptom of COVID-19

In a new study, scientists researched olfactory loss and dysfunction among COVID-19 patients to objectively characterize it as a symptom of COVID-19.

Alcohol consumption may be a modifiable risk factor for age-related macular degeneration

Even though Dry January is over, new research suggests you may want to consider keeping the no-alcohol challenge going all year, especially if you're among the nearly 2 million Americans who have age-related macular degeneration (AMD), a sight-threatening eye condition.
