Lost memories might be able to be restored, suggests research into marine snail
New research indicates that lost memories can be restored, according to new research into a type of marine snail called Aplysia. The findings offer some hope for patients in the early stages of Alzheimer's disease.

New technique reveals immune cell motion
Neutrophils, cells recruited by the immune system to fight infection, need to move through a great variety of tissues. New research shows how neutrophils move through confined spaces in the body. A new system can mimic tissues of different densities and stiffness, enabling improved development and testing of drugs.

Gene critical for proper brain development discovered
A genetic pathway has been found that accounts for the extraordinary size of the human brain. The research team has identified a gene, KATNB1, as an essential component in a genetic pathway responsible for central nervous system development in humans and other animals.

A vegetarian carnivorous plant
Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains.

A clear, molecular view of how human color vision evolved
Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a detailed and complete picture of the evolution of human color vision.

Cell-associated HIV mucosal transmission: The neglected pathway
Scientists are challenging dogma about the transmission of the human immunodeficiency virus type 1 (HIV-1). Most research has focused on infection by free viral particles, while this group of researchers proposes that HIV is also transmitted by infected cells.

Ibuprofen use leads to extended lifespan in several species, study shows
A common over-the-counter drug that tackles pain and fever may also hold keys to a longer, healthier life, according to a Texas A&M AgriLife Research scientist. Regular doses of ibuprofen extended the lifespan of multiple species.

550-million-year-old fossils provide new clues about fossil formation
A new study is challenging accepted ideas about how ancient soft-bodied organisms become part of the fossil record. Findings suggest that bacteria involved in the decay of those organisms play an active role in how fossils are formed -- often in a matter of just a few tens to hundreds of years. Understanding the relationship between decay and fossilization will inform future study and help researchers interpret fossils in a new way.

Using power of computers to harness human genome may provide clues into Ebola virus
New work is blending the power of computers with biology to use the human genome to remove much of the guesswork involved in discovering cures for diseases. A corresponding article describes how key genes that are present in our cells could be used to develop drugs for Ebola virus disease.

Protection of mouse gut by mucus depends on microbes
The quality of the colon mucus in mice depends on the composition of gut microbiota, reports a research team whose work suggests that bacteria in the gut affect mucus barrier properties in ways that can have implications for health and disease.
