Most cases of never-smokers’ lung cancer treatable with mutation-targeting drugs
- ScienceDaily
- 21/9/30 23:10
Despite smoking's well-known role in causing lung cancer, a significant number of patients who develop lung tumors have never smoked. While scientists are still working to understand what spurs cancer in so-called 'never-smokers,' a study suggests that 78% to 92% of lung cancers in patients who have never smoked can be treated with precision drugs already approved by the Food and Drug...

New treatment for inflammatory bowel disease: Opioids may cure that 'bad gut feeling'
- ScienceDaily
- 21/9/30 23:10
Opioid receptors play key roles in regulating our senses and emotions. Recently, their discovery outside the nervous system raised several questions about the effects of opioids on the immune system. Now, researchers have shown that KNT-127 -- a drug that targets delta opioid receptors -- can reduce pro-inflammatory signals in the colon. Their research highlights the immunomodulatory properties of...

Scientists used a nuclear dating technique to study the dynamics of the Floridan Aquifer. The findings show the promise of this emerging technique to help understand geological processes and to forecast the effects of climate change on coastal aquifers.
Study on African buffalo offers insights on persistence of highly contagious pathogens
- ScienceDaily
- 21/9/30 22:04
A new study on foot-and-mouth disease among buffalo in South Africa could help explain how certain extremely contagious pathogens are able to persist and reach endemic stage in a population, long after they've burned through their initial pool of susceptible hosts.

- 21/9/30 22:04
Engineers have achieved a practical mechanism for 'full-duplex nonreciprocity,' a property in metamaterials that allows for manipulation of both incoming and reflective beams of light.
Dynamic pregnancy intentions
- ScienceDaily
- 21/9/30 22:04
A study found that pregnancy intentions often change over as short as a 12-month time period, and that they specifically vary with partner status, household income, and employment status.
Looking beyond DNA to see cancer with new clarity
- ScienceDaily
- 21/9/30 20:07
Researchers have mapped out how hundreds of mutations involved in two types of cancer affect the activity of proteins that are the ultimate actors behind the disease. The work points the way to identifying new precision treatments that may avoid the side effects common with much current chemotherapy.
Toothy grins from the past: Ancient birds replaced their teeth like living crocodilians
- ScienceDaily
- 21/9/30 20:07
The first 3D reconstructions of extinct Cretaceous birds reveal a reptilian tooth replacement pattern.
Signaling from neighboring cells provides power boost within axons
- ScienceDaily
- 21/9/30 20:07
Nerve cells (neurons) send signals throughout the brain and the body along long processes called axons; these communication and information processes consume high levels of energy. A recent study shows that the support cells around axons provide a way to boost local energy production. The new findings help explain how long axons maintain sufficient energy levels and could have implications for the...
More effective treatment of Alzheimer’s
- ScienceDaily
- 21/9/30 20:07
Researchers have designed new antibodies that might provide more effective treatment methods for Alzheimer's disease. By designing antibodies that bind even to the smaller aggregates, or clumps, of the amyloid-beta protein, it may be possible to check the progress of the disease.
Safer treatment for deep-seated tumors
- ScienceDaily
- 21/9/30 20:07
Scientists have detailed the effects of copper cysteamine, a next-generation cancer photo-drug.
Connecting the dots between material properties and qubit performance
- ScienceDaily
- 21/9/30 20:07
Scientists studying superconducting qubits identified structural and chemical defects that may be causing quantum information loss -- an obstacle to practical quantum computation.
Movement of genes within cells helps organisms tell time
- ScienceDaily
- 21/9/30 20:07
Using the relatively simple clocks found in fruit flies, researchers reveal that the subcellular location of clock proteins and genes fluctuates with the daily passage of time, indicating that spatial information is translated into time-related signals.
Scientists reverse pancreatic cancer progression in ‘time machine’ made of human cells
- ScienceDaily
- 21/9/30 20:07
What makes pancreatic cancer so deadly is its covert and quick spread. Now, a 'time machine' has shown a way to reverse the course of cancer before it spreads throughout the pancreas.
Learning is more effective when active
- ScienceDaily
- 21/9/30 20:07
Engaging students through interactive activities, discussions, feedback and AI-enhanced technologies resulted in improved academic performance compared to traditional lectures, lessons or readings, faculty concluded after collecting research into active learning. The research also found that effective active learning methods use not only hands-on and minds-on approaches, but also hearts-on,...
New analytical technique helps researchers spot subtle differences in subcellular chemistry
- ScienceDaily
- 21/9/30 19:48
Researchers can now rapidly isolate and chemically characterize individual organelles within cells. The new technique tests the limits of analytical chemistry and rapidly reveals the chemical composition of organelles that control biological growth, development and disease.
AMD: Reading ability crucial indicator of functional loss
- ScienceDaily
- 21/9/30 19:48
In geographic atrophy, a late form of age-related macular degeneration (AMD), reading ability is closely related to the altered retinal structure. Reading speed makes everyday functional impairment measurable, which the most common functional test in ophthalmology -- the best-corrected visual acuity assessment - cannot reflect. Retinal imaging can be used to assess loss of reading ability even...
‘Planet confusion’ could slow Earth-like exoplanet exploration
- ScienceDaily
- 21/9/30 19:48
A new study finds that next-generation telescopes used to see exoplanets could confuse Earth-like planets with other types of planets in the same solar system.
New nanoparticle developed for intravenous cancer immunotherapy
- ScienceDaily
- 21/9/30 18:50
Cancer immunotherapy seeks to turn 'cold' tumors into 'hot' tumors -- those that respond to immunotherapy -- by awakening and enlisting the body's own immune system.
Scientists create material that can both move and block heat
- ScienceDaily
- 21/9/30 18:50
Scientists have invented a new way to funnel heat around at the microscopic level: a thermal insulator made using an innovative technique. They stack ultra-thin layers of crystalline sheets on top of each other, but rotate each layer slightly, creating a material with atoms that are aligned in one direction but not in the other. The result is a material that is extremely good at both containing...
Bigleaf maple decline tied to hotter, drier summers in Washington state, U.S.
- ScienceDaily
- 21/9/30 17:11
A new study has found that recent bigleaf maple die-off in Washington is linked to hotter, drier summers that predispose this species to decline. These conditions essentially weaken the tree's immune system, making it easier to succumb to other stressors and diseases.
