(MEMPHIS, Tenn. – May 29, 2023) St. Jude Children’s Research Hospital scientists discovered how the current epizootic H5N1 avian influenza virus (bird flu) gained new genes and greater virulence as it spread west. Researchers showed that the avian virus could severely infect the brains of mammalian research models, a notable departure from previous related strains of the virus. The researchers genetically traced the virus’ expansion across the continent and its establishment in wild waterfowl populations to understand what makes it so different. The study was recently published in Nature Communications.   “We ...

Less than two percent of the human genome codes for proteins, with the rest being noncoding and likely helping with gene regulation. Mutations in the noncoding genome often trigger trait changes that cause disease or disability by altering gene expression. However, it can be hard for scientists to track down which of numerous variants associated with a disease or other complex trait are the causal ones and to understand the mechanism of their effects. Researchers at the Brigham developed a new computational approach that hones in on small regions of the noncoding genome that genome-wide association studies (GWAS) identified ...

With a warmer climate creating more humid conditions in the Northeast, extreme precipitation events — defined as about 1.5 or more inches of heavy rainfall or melted snowfall in a day — are projected to increase in the Northeast by 52% by the end of the century, according to a new Dartmouth study. The findings are published in Climatic Change. "As climate change brings warmer temperatures, you have more water vapor in the atmosphere, which creates the right conditions for extreme precipitation," says first author Christopher J. Picard '23, an earth sciences major and undergraduate researcher in the Applied Hydroclimatology Group ...

A little-known bacterium — a distant cousin of the microbes that cause tuberculosis and leprosy — is emerging as a public health threat capable of causing severe lung infections among vulnerable populations, those with compromised immunity or reduced lung function. Recent research found that various strains of the bacterium, Mycobacterium abscessus, were genetically similar, stoking fears that it was spreading from person to person. But a new study by Harvard Medical School researchers published ...

An experimental “decoy” provided long-term protection from infection by the pandemic virus in mice, a new study finds. Led by researchers at NYU Grossman School of Medicine, the work is based on how the virus that causes COVID-19, SARS-CoV-2, uses its spike protein to attach to a protein on the surface of the cells that line human lungs. Once attached to this cell surface protein, called angiotensin converting enzyme 2 (ACE2), the virus spike pulls the cell close, enabling the virus to enter the cell and hijack its machinery to make viral copies.  Earlier in the pandemic, pharmaceutical ...

Plant growth is driven by light and supplied with energy through photosynthesis by green leaves. It is the same for roots that grow in the dark – they receive the products of photosynthesis, in particular sucrose, i.e. sugar, via the central transportation pathways of phloem. Dr. Stefan Kircher and Prof. Dr. Peter Schopfer from the University of Freiburg’s Faculty of Biology have now shown in experiments using the model plant Arabidopsis thaliana (thale cress) that the sucrose not only guarantees the supply of carbohydrates to the roots, it also acts as a signal transmitter for ...

One of the primary drivers of climate change is excess greenhouse gases like carbon dioxide in the atmosphere. Mitigating climate change in the coming century will require both decarbonization — electrifying the power grid or reducing fossil fuel-guzzling transportation —  and removing already existing carbon dioxide from the atmosphere, a process called carbon dioxide removal. Researchers at the Georgia Institute of Technology and Yale University are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves — known as blue carbon ecosystems — naturally capture ...

HOUSTON – (May 30, 2023) – Conventional implantable medical devices designed for brain stimulation are often too rigid and bulky for what is one of the body’s softest and most delicate tissues. To address the problem, Rice University engineers have developed minimally invasive, ultraflexible nanoelectrodes that could serve as an implanted platform for administering long-term, high-resolution stimulation therapy. According to a study published in Cell Reports, the tiny implantable devices formed stable, long-lasting and seamless tissue-electrode ...

DARIEN, IL – A new study to be presented at SLEEP 2023 found that teens with greater variability in their sleep patterns have a higher risk for school-related problems. Results show that the teens with greater night-to-night variability in the time they fell asleep were 42% more likely to have been suspended or expelled in the past two years, 29% more likely to have received a D or F in any course, and 26% more likely to have ever failed a course. The likelihood of suspension or expulsion was also 31% higher in teens with greater variability in sleep duration. “Variability in sleep duration and later sleep ...

Today’s substance use prevention efforts ignore individual genetic risk, but Rutgers research suggests DNA test results may eventually enhance prevention and treatment and improve outcomes. Investigators recruited 325 college students, provided them with varying levels of information about alcohol use disorder and how genetics affect addiction risk and asked them how they would react to learning they had high, medium and low genetic tendencies toward alcoholism. The results provided two significant supports for eventually using real genetic risk scores in actual addiction prevention efforts. First, participants understood what those scores indicated; they recognized that higher ...

Transportation accounts for roughly one-third of U.S. greenhouse gas emissions, and adoption of electric vehicles are seen by many experts in government and the private sector as a vital tool in efforts to reduce carbon emissions. Roughly a decade ago, EVs accounted for a tiny fraction of overall car sales. As of March 2023, they make up 7% of new sales “What changed between then and now?” asks Kenneth Gillingham, professor of environmental and energy economics at the Yale School of the Environment. ...

DARIEN, IL – Cortisol levels in late pregnancy can predict the sleep of infants, according to a new study to be presented at the SLEEP 2023 annual meeting.  Results show that newborns with higher levels of cortisol in their hair samples took longer to fall asleep at 7 months of age. Neonatal hair cortisol is a measure of fetal cortisol in the last trimester of pregnancy.  “Although increases in cortisol across pregnancy are normal and important for preparing the fetus for birth, our findings ...

May 30, 2023 That’s Not Nuts: Almond Milk Yogurt Packs an Overall Greater  Nutritional Punch than Dairy-Based UMass Amherst food science major completes comparison of 612 plant-based and dairy yogurts AMHERST, Mass. – In a nutritional comparison of plant-based and dairy yogurts, almond milk yogurt came out on top, according to research led by a University of Massachusetts Amherst food science major. “Plant-based yogurts overall have less total sugar, less sodium and more fiber than dairy, but they have less protein, calcium and potassium than dairy yogurt,” ...

COLUMBUS, Ohio – While it can take years for the pharmaceutical industry to create medicines capable of treating or curing human disease, a new study suggests that using generative artificial intelligence could vastly accelerate the drug-development process.  Today, most drug discovery is carried out by human chemists who rely on their knowledge and experience to select and synthesize the right molecules needed to become the safe and efficient medicines we depend on. To identify the synthesis paths, scientists often employ a technique called retrosynthesis – a method for creating potential drugs by working backward from the wanted molecules and searching for chemical reactions ...

May 30, 2023, Mountain View, CA – Akshay Suresh, a graduate student at Cornell University, spearheads an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy. Suresh and his co-authors detail the project’s results thus far in a paper accepted for publication in the Astronomical Journal, “A 4–8 GHz Galactic Center Search for Periodic Technosignatures.” BLIPSS ...

“In this study, we present novel transcriptional dependencies between MALAT1 and MAPK-pathway-associated genes in melanoma.” BUFFALO, NY- May 30, 2023 – A new research paper was published in Oncotarget's Volume 14 on May 26, 2023, entitled, “Deconstructing the role of MALAT1 in MAPK-signaling in melanoma: insights from antisense oligonucleotide treatment.” The long non-coding RNA (lncRNA) MALAT1 is a regulator of oncogenesis and cancer progression. MAPK-pathway upregulation is the main event in the development and progression of human cancer, including melanoma and recent studies have shown that MALAT1 has a significant impact on the ...

The low blood oxygen levels of obstructive sleep apnea cause widespread changes in gene activity throughout the day, according to a new study in the open-access journal PLOS Biology by David Smith of Cincinnati Children’s Hospital Medical Center, US, and colleagues. The finding may lead to tools for earlier diagnosis and tracking of the disorder. Obstructive sleep apnea (OSA) occurs when the airway becomes blocked (usually by soft tissue, associated with snoring and interrupted breathing during the night), resulting in intermittent hypoxia (low blood oxygen) and disrupted sleep. ...

Since it was identified in 1984 as the cause of Acquired Immune Deficiency Syndrome (AIDS), the human immunodeficiency virus (HIV) has infected more than 80 million people and been responsible for some 40 million deaths worldwide, according to the World Health Organization (WHO). Currently, the WHO reports more than 38 million people globally live with the retrovirus, and each year, another 1 million new cases are diagnosed. While antiretroviral therapy helps keep HIV in check, patients must stay on their medication to prevent the development of AIDS. Scientists have spent years trying to develop an ...

INDIANAPOLIS—Researchers at Indiana University School of Medicine have discovered alternative gene splicing, which occurs during gene expression, can impact a person’s risk of alcohol use disorder (AUD). They recently published their findings in Molecular Psychiatry. “AUD is a common and complex genetic disorder that happens people experience problems related to excessive alcohol consumption,” said Rudong Li, PhD, a postdoctoral fellow in the YunLong Liu, PhD Laboratory and lead author of the paper. “This discovery has revealed ...
