When it comes to monarchs, fall migration matters

New research shows that a critical piece of the butterfly's annual cycle was missing -- the fall migration.

Bartonella and sudden-onset adolescent schizophrenia

In a new case study, researchers describe an adolescent human patient diagnosed with rapid onset schizophrenia who was found instead to have a Bartonella henselae infection (associated with cat scratch fever).

Algal library lends insights into genes for photosynthesis

To identify genes involved in photosynthesis, researchers built a library containing thousands of single-celled algae, each with a different gene mutation. The library, which took nine years to construct, has already helped researchers identify 303 genes associated with photosynthesis including 21 newly discovered genes with high potential to provide new insights into this life-sustaining process.

World’s oldest semen still viable

Ram semen stored for 50 years has been used to successfully impregnate 34 ewes, with fertility rates as high as recently stored semen.

Dormant viruses activate during spaceflight

Herpes viruses reactivate in more than half of crew aboard Space Shuttle and International Space Station missions. While only a small proportion develop symptoms, virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond.

Nitrogen pollution’s path to streams weaves through more forests (and faster) than suspected

Scientists have completed one of the largest and longest examinations to trace unprocessed nitrate movement in forests. The team found that some nitrate occasionally moves too fast for biological uptake, resulting in 'unprocessed' nitrate bypassing the otherwise effective filter of forest biology.

Chemical probe can regulate signaling pathway and block cell invasion by arboviruses

Dysregulation of the signaling pathway known as the beta-catenin-dependent Wnt can also cause embryo malformation and contribute for the development of breast and cervical cancer.

A repellent odor inhibits the perception of a pleasant odor in vinegar flies

Scientists have discovered that repellent odors suppress the perception of pleasant smells. This happens because certain brain structures that respond to attractive odors are inhibited by a repellent one. These processes in the brain are also reflected in the behavior of the flies. This helps them to avoid spoiled or infected food sources, which would have fatal consequences for the flies and their offspring.

Higher egg and cholesterol consumption hikes heart disease and early death risk

Cancel the cheese omelet. A large, new study of nearly 30,000 people reports adults who ate more eggs and dietary cholesterol had a significantly higher risk of cardiovascular disease and death from any cause. People need to consume lower amounts of cholesterol to have a lower risk of heart disease, the study authors said.

Uncovering uncultivated microbes in the human gut

A human's health is shaped both by environmental factors and the body's interactions with the microbiome, particularly in the gut. Genome sequences are critical for characterizing individual microbes and understanding their functional roles. However, previous studies have estimated that only 50 percent of species in the gut microbiome have a sequenced genome, in part because many species have not yet been cultivated for study.
