Fruit fly breakthrough may help human blindness research

For decades, scientists have known that blue light will make fruit flies go blind, but it wasn’t clear why. Now, a Purdue University study has found how this light kills cells in the flies’ eyes, and that could prove a useful model for understanding human ocular diseases such as macular degeneration.




Researchers Explore Psychological Effects of Climate Change

Wildfires, extreme storms and major weather events can seem like a distant threat, but for those whose lives have been directly impacted by these events, the threat hits much closer to home.




Wasatch Front Inversions Could Cause More Than 200 Cases of Pneumonia Each Year

Air pollution trapped along the Wasatch Front by winter inversions are estimated to send more than 200 people to the emergency room with pneumonia each year, according to a study by University of Utah Health and Intermountain Healthcare. Bad air quality especially erodes the health of adults over age 65, a population particularly vulnerable to the effects of pneumonia.

Rhythmic interactions between cortical layers underlie working memory

Working memory is a sort of “mental sketchpad” that allows you to accomplish everyday tasks such as calling in your hungry family’s takeout order and finding the bathroom you were just told “will be the third door on the right after you walk straight down that hallway and make your first left.” It also allows your mind to go from merely responding to your environment to consciously asserting your agenda.




Biologists' new peptide could fight many cancers

MIT biologists have designed a new peptide that can disrupt a key protein that many types of cancers, including some forms of lymphoma, leukemia, and breast cancer, need to survive.




Asthma Costs the U.S. Economy More than $80 Billion Per Year

Asthma costs the U.S. economy more than $80 billion annually in medical expenses, missed work and school days and deaths, according to new research published online in the Annals of the American Thoracic Society.

Math Can Predict How Cancer Cells Evolve

Applied mathematics can be a powerful tool in helping predict the genesis and evolution of different types of cancers, a study from the University of Waterloo has found.

How Incurable Mitochondrial Diseases Strike Previously Unaffected Families

Researchers have shown for the first time how children can inherit a severe – potentially fatal – mitochondrial disease from a healthy mother. The study, led by researchers from the MRC Mitochondrial Biology Unit at the University of Cambridge, reveals that healthy people harbour mutations in their mitochondrial DNA and explains how cases of severe mitochondrial disease can appear unexpectedly in previously unaffected families.




UCLA scientists make cells that enable the sense of touch

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have, for the first time, coaxed human stem cells to become sensory interneurons — the cells that give us our sense of touch. The new protocol could be a step toward stem cell–based therapies to restore sensation in paralyzed people who have lost feeling in parts of their body.




Flu Vaccine Spinout Secures a Further £20m in Funding

Vaccitech, an Oxford University spinout company developing a universal flu vaccine, among other vaccine-related products, has secured £20 million in Series A financing. 




Energy Drinks Can Negatively Impact Health of Youth

Over half of Canadian youth and young adults who have consumed energy drinks have experienced negative health effects as a result, according to a study from the University of Waterloo.

Research Shows Importance of Second Pediatric Blood Pressure Screening

Nearly one-quarter of children and teens who had their blood pressure screened at a primary care appointment showed a reading in the hypertensive range, but less than half of those readings could be confirmed after the blood pressure was repeated, according to a new Kaiser Permanente study released today in The Journal of Clinical Hypertension. The research shows the importance of taking a second blood pressure reading for those ages 3 to 17 years when the first reading is elevated.

Can Muesli Help Against Arthritis?

It is well known that healthy eating increases our general sense of wellbeing. Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered that a fibre-rich diet can have a positive influence on chronic inflammatory joint diseases, leading to stronger bones.

Restaurant, Bar Smoking Bans Impact Smoking Behaviors, Especially for the Highly Educated

Smoking risk drops significantly in college graduates when they live near areas that completely banned smoking in bars and restaurants, according to a new Drexel University study published in the American Journal of Epidemiology.




Surprise: A Virus-Like Protein Is Important for Cognition and Memory

A protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. The protein, called Arc, has properties similar to those that viruses use for infecting host cells, and originated from a chance evolutionary event that occurred hundreds of millions of years ago.




Babies Stir Up Clouds of Bio-Gunk When They Crawl

When babies crawl, their movement across floors, especially carpeted surfaces, kicks up high levels of dirt, skin cells, bacteria, pollen, and fungal spores, a new study has found. The infants inhale a dose of bio bits in their lungs that is four times (per kilogram of body mass) what an adult would breathe walking across the same floor.

Machine learning predicts new details of geothermal heat flux beneath the Greenland Ice Sheet

A paper appearing in Geophysical Research Letters uses machine learning to craft an improved model for understanding geothermal heat flux — heat emanating from the Earth’s interior — below the Greenland Ice Sheet. It’s a research approach new to glaciology that could lead to more accurate predictions for ice-mass loss and global sea-level rise.




Stanford mechanical engineers give breast cancer research a boost

One of the most puzzling questions in breast cancer research is why some tumors stay put, while rogue cells from others break free and spread to surrounding tissues, the first step toward creating a more lethal disease. Although researchers have found some signs in mutated genes or telltale proteins on the cell’s surface, those discoveries don’t tell the whole story.
