For the past 20 years, exoplanets known as 'hot Jupiters' have puzzled astronomers. These giant planets orbit 100 times closer to their host stars than Jupiter does to the Sun, which increases their surface temperatures. But how and when in their history did they migrate so close to their star? Now, an international team of astronomers has announced the discovery of a very young hot Jupiter orbiting in the immediate vicinity of a star that is barely two million years old -- the stellar equivalent of a week-old infant. This first-ever evidence that hot Jupiters can appear at such an early stage represents a major step forward in our understanding of how planetary systems form and evolve.
The US clothing industry is a multi-billion dollar industry, but for the millions of Americans with disabilities and their families, a lack of options in the apparel industry presents daily challenges. One researcher has found that the lack of adequate, accessible apparel created barriers for people with disabilities from engaging in their communities. She identified the need for innovation in design, production, distribution and sale of adaptive clothing.
Reader itwbennett writes: A person nicknamed AppleJ4ck, who has been previously been linked to Lizard Squad, a group notorious for DDoS attacks against gaming platforms, including the PlayStation Network and Xbox Live, has taken credit for server outages affecting gaming giant Blizzard (Alternate source: ZDNet) Monday morning. The outages led to authentication lockouts for gamers attempting to access Overwatch, Hearth Stone, World of Warcraft, Diablo, Heroes of the Stone, and others. During the outage, AppleJ4ck said Monday's problems were just a test, promising more outages in the future.
Mapping the molecular structure where medicine goes to work is a crucial step toward drug discovery against deadly diseases. Researchers have taken that critical first step by providing a crystal structure of the extracellular domain, or ECD, of ZIP4 -- the exclusive protein responsible for the uptake of zinc from food. The ZIP family consists of thousands of zinc/iron transporter proteins, and this work represents the first-ever structural information of the ZIP family at the atomic level.
Last month, a scientist harvested about 145 pounds of Purple Straw seed, which was grown from less than half a pound. Purple Straw is the only heirloom wheat to have been cultivated continually in the South from the Colonial Period into the last quarter of the 20th century.
New research has discovered peptides from two crop species that have antimicrobial effects on bacteria implicated in food spoilage and food poisoning. They are similar in structure to a human peptide used to guard against beer-spoiling bacteria.
Due to a subgroup effect, reviewers have found that there is an indication of a minor added benefit for patients with diabetes, and an indication of a considerable added benefit for patients without diabetes, when using Sacubitril/valsartan in heart failure.
Scientists have identified four new risk genes that are altered in patients with multiple sclerosis. The results point to a possible involvement of cellular mechanisms in the development of the disease, through which environmental influences affect gene regulation.
Three to 5 percent of the European population is allergic to insect venom, and many of them are at risk of anaphylaxis if they are stung. Some patients do not respond properly to immunotherapy and in some cases the treatment has reduced or no effect at all -- which can be fatal. Researchers are now developing artificial allergens and human antibodies in order to enable individualized immunotherapeutic treatment.
Birds of the species Parus Major (great tit) living in an urban environment are at greater risk of dying young than great tits living outside cities. Research results in Sweden show that urban great tits have shorter telomeres than others of their own species living in rural areas. According to the researchers, the induced stress that the urban great tits are experiencing is what results in shorter telomeres and thereby increases their risk of dying young.
Astronomers have discovered the youngest fully formed exoplanet ever detected. The newfound planet, K2-33b, is a bit larger than Neptune and whips tightly around its star every five days. It is only 5 to 10 million years old, making it one of a very few newborn planets found to date.
On Monday (June 20), the full moon will fall on the solstice for the first time since 1948. To celebrate this special occasion, the online Slooh Community Observatory will broadcast views of the moon live from the Canary Islands.
