Researchers found a modified peptide carrier that was delivering the siRNA drug by adhering to and potentially moving along cell filopodia, leading to more efficient cell entry and improved gene silencing.

Mosquitoes are one of humanity's greatest nemeses, estimated to spread infections to nearly 700 million people per year and cause more than one million deaths.
Study shows risk doubles in women and goes up by 50 percent in men.
When a single gene in a cell is turned on or off, its resulting presence or absence can affect the function and survival of the cell. Researchers have now successfully catalogued this effect in the human neuron by separately toggling each of the 20,000 genes in the human genome.
Using DNA from greenhouse-grown plants representing all species and hundreds of varieties of watermelon, scientists discovered that watermelons most likely came from wild crop progenitors in northeast Africa. The study corrects a 90-year-old mistake that had previously tied watermelons to South Africa. The genetic research is consistent with newly interpreted Egyptian tomb paintings that suggest...
Clownfish are instantly recognizable by their white stripes, which appear as they mature from larvae into adults. But how these distinctive patterns form has long remained a mystery. Now, a new study has found that the speed at which these white bars form depends on the species of sea anemone in which the clownfish live. The scientists also discovered that thyroid hormones, which play a key role...
The first detailed cross-section of a galaxy broadly similar to the Milky Way reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt.
New research shows that concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are comparable to rivers in industrial China, an unexpected finding that is raising questions about the effects of glacial melting in an area that is a major exporter of seafood.
Scientists have shown that the presence of both immune-suppressive and non-suppressive bacteria in the plant root microbiota is crucial to strike a balance between plant growth and plant defense, and maintain plant-microbe homeostasis.
Researchers deciphered the cellular mechanisms through which tendons can adapt to mechanical stresses. People who carry a certain variant of a gene that is key to this mechanism show improved jumping performance.
A new study by ecologists warns that heat-induced male infertility will see some species succumb to the effects of climate change earlier than thought. Currently, scientists are trying to predict where species will be lost due to climate change so they can plan effective conservation strategies. However, research on temperature tolerance has generally focused on the temperatures that are lethal to...
Scientists have used a new conservation strategy to give the bridled nailtail wallaby a head start in life.
Scientists have discovered a new role for bile acids: they curb appetite by entering the brain. Their findings provide new insights into the signals and mechanisms by which satiety is controlled and may have implications for treating obesity.
A new low-cost and sustainable technique would boost the possibilities for hospitals and clinics to deliver therapeutics with aerogels, a foam-like material now found in such high-tech applications as insulation for spacesuits and breathable plasters.
Researchers report the climate clues that can be found by analyzing the magnetic fossil particles, or magnetofossils.
Scientists report that it is possible to detect and predict heat damage in crops by measuring the fluorescent light signature of plant leaves experiencing heat stress. If collected via satellite, this fluorescent signal could support widespread monitoring of growth and crop yield under the heat stress of climate change, the researchers say.
Researchers showed that adding gamification with either competition or support increased physical activity for patients with Type 2 diabetes.
Scientists have made significant progress in the development of a nasal spray treatment for patients with Parkinson's disease.
Researchers have uncovered a new role for a distinct inhibitory cell cluster in the amygdala, acting to dynamically modulate synaptic connections during fear learning.
Researchers at Lund University in Sweden have developed an algorithm that combines data from a simple blood test and brief memory tests, to predict with great accuracy who will develop Alzheimer's disease in the future. The findings are published in Nature Medicine.
Researchers proposed five strategies to untangle the impacts of colonialism on research and thinking in ecology.
As climate change intensifies, wildfires in the West are behaving in ways that were unimaginable in the past -- and the common disaster response approaches are woefully unprepared for this new reality. Researchers now proposed a framework for simulating dire scenarios, which the authors define as scenarios where there is less time to evacuate an area than is required.
Scientists analyzed ground movements measured by Interferometric Synthetic Aperture Radar (InSAR) satellite data and GPS stations to precisely model where magma intruded and how magma influx changed over time, as well as where faults under the flanks moved without generating significant earthquakes.
Absentee property ownership in many small college football towns has a negative impact on permanent residents of those communities, according to a new study. The research is the first known attempt to quantify and map local geographies of gameday home investments.
Researchers found that risk of subsequent moderate or worse hearing loss was up to 40 percent higher in study participants with osteoporosis or LBD.
