Chances of eliminating HIV infection increased by novel dual gene-editing approach
- ScienceDaily
- 23/5/2 21:54
Gene-editing therapy aimed at two targets -- HIV-1, the virus that causes AIDS, and CCR5, the co-receptor that helps the virus get into cells -- can effectively eliminate HIV infection, new research shows. The study combines a dual gene-editing strategy with antiretroviral drugs to cure animals of HIV-1.
'Golden' fossils reveal origins of exceptional preservation
- ScienceDaily
- 23/5/2 21:54
A recent study found that many of the fossils from Germany's Posidonia shale do not get their gleam from pyrite, commonly known as fool's gold, which was long thought to be the source of the shine. Instead, the golden hue is from a mix of minerals that hints at the conditions in which the fossils formed. The discovery is important for understanding how the fossils -- which are among the world's...

Stress causes the levels of Alzheimer's proteins to rise in females' brains but not males' brains, according to a new study. This difference may contribute to women's greater risk of developing Alzheimer's disease.
Upcycling method turns textile trash to functional coatings
- ScienceDaily
- 23/5/2 19:23
In an effort to make textiles more sustainable, a new method allows researchers to break old clothing down chemically and reuse polyester compounds to create fire resistant, anti-bacterial or wrinkle-free coatings that could then be applied to clothes and fabrics.
Joyful music could be a game changer for virtual reality headaches
- ScienceDaily
- 23/5/2 19:23
Listening to music could reduce the dizziness, nausea and headaches virtual reality users might experience after using digital devices, research suggests. Cybersickness -- a type of motion sickness from virtual reality experiences such as computer games -- significantly reduces when joyful music is part of the immersive experience, the study found. The intensity of the nausea-related symptoms of...
Self-folding origami machines powered by chemical reaction
- ScienceDaily
- 23/5/2 19:23
Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Scientists present evidence for a billion-years arms race between viruses and their hosts
- ScienceDaily
- 23/5/2 19:22
Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom and their hosts.
A stormy, active sun may have kickstarted life on Earth
- ScienceDaily
- 23/5/2 19:22
The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basic building blocks of proteins and organic life.
Fossil find in California shakes up the natural history of cycad plants
- ScienceDaily
- 23/5/2 19:22
According to researchers, a new analysis of an 80-million-year-old permineralized pollen cone found in the Campanian Holz Shale formation located in Silverado Canyon, California, offers a more accurate cycad natural history -- one where the plants diversified during the Cretaceous.
'Zero plant extinction' is possible, says plant ecologist
- ScienceDaily
- 23/5/2 19:22
Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect than animals and play a pivotal role in bolstering our food, fuel, and medical systems. A plant ecologist suggests an approach for preventing all future land plant extinctions across the globe which...
Researchers model 'link' between improved photosynthesis and increased yield
- ScienceDaily

Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Oil and gas infrastructure hurting nesting birds in globally important breeding area in arctic Alaska
- ScienceDaily
- 23/5/2 19:19
A new study that analyzed 17 years of migratory bird-nesting data in Prudhoe Bay, Alaska, revealed that nest survival decreased significantly near high-use oil and gas infrastructure and its related noise, dust, traffic, air pollution, and other disturbances.
Could wearables capture well-being?
