Hide and seek: Revealing camouflaged bacteria
A research team at the Biozentrum of the University of Basel has discovered an protein family that plays a central role in the fight against the bacterial pathogen Salmonella within the cells. The so called interferon-induced GTPases reveal and eliminate the bacterium's camouflage in the cell, enabling the cell to recognize the pathogen and to render it innocuous. The findings are published in the current issue of the science magazine Nature.

Sperm meets egg: Protein essential for fertilization discovered
Fertilisation occurs when an egg and a sperm recognise each other and fuse together. Until now, the biology behind this interaction, fundamental to life, has remained a mystery. In a study published in Nature, scientists from the Wellcome Trust Sanger Institute have discovered the first fundamental biological interaction between the sperm and the egg. This discovery may help to improve fertility treatments and the development of new contraceptives. Here is a link to an additional explanatory video: https://www.youtube.com/watch?v=LJNuZQCwWaU.

Medieval slave trade routes in Eastern Europe extended from Finland and the Baltic Countries to Asia
The routes of slave trade in Eastern Europe in the medieval and pre-modern period extended all the way to the Caspian Sea and Central Asia. A recent study completed at the University of Eastern Finland suggests that persons captured during raids into areas which today constitute parts of Finland, the Russian Karelia and the Baltic Countries ended up being sold on these remote trade routes.

Ancient shark fossil reveals new insights into jaw evolution
The skull of a newly discovered 325-million-year-old shark-like species suggests that early cartilaginous and bony fishes have more to tell us about the early evolution of jawed vertebrates -- including humans -- than do modern sharks, as was previously thought. The new study, led by scientists at the American Museum of Natural History, shows that living sharks are actually quite advanced in evolutionary terms, despite having retained their basic 'sharkiness' over millions of years.

Searching for dark energy with neutrons
It does not always take a huge accelerator to do particle physics: First results from a low energy, table top alterative takes validity of Newtonian gravity down by five orders of magnitude and narrows the potential properties of the forces and particles that may exist beyond it by more than one hundred thousand times. Gravity resonance spectroscopy, a method developed at the Vienna University of Technology, is so sensitive that it can now be used to search for Dark Matter and Dark Energy.

Masculine boys, feminine girls more likely to engage in cancer risk behaviors
The most 'feminine' girls and 'masculine' boys -- are more likely than their peers to engage in behaviors that pose cancer risks, according to a new study led by Harvard School of Public Health researchers. The most feminine teenage girls use tanning beds more frequently and are more likely to be physically inactive, while the most masculine teenage boys are more likely to chew tobacco and smoke cigars compared with gender-nonconforming peers.

Warm US West, cold East: A 4,000-year pattern
Last winter's curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East. A University of Utah-led study shows that pattern became more pronounced 4,000 years ago, and suggests it may worsen as Earth's climate warms.

Celldex's Phase 1 study of CDX-1401 published in Science Translational Medicine
Celldex Therapeutics Inc. announced today that final data from its Phase 1 study of CDX-1401 in solid tumors, including long-term patient follow-up, have been published in Science Translational Medicine. The data demonstrate robust antibody and T cell responses and evidence of clinical benefit in patients with very advanced cancers and suggest that CDX-1401 may predispose patients to better outcomes on subsequent therapy with checkpoint inhibitors.

Scientists explain how memories stick together
Scientists at the Salk Institute have created a new model of memory that explains how neurons retain select memories a few hours after an event. This new framework provides a more complete picture of how memory works, which can inform research into disorders liked Parkinson's, Alzheimer's, post-traumatic stress and learning disabilities.

Irrigated agriculture -- precious habitat for the long-billed curlew
Despite the recent rainfall, California is still in a drought, so not only are water supplies limited, but demand for water is increasing from a variety of uses. In a recent study published by Point Blue Conservation Science (Point Blue) and Audubon California in the journal Western Birds, scientists document the importance of irrigated agricultural crops in California's Central Valley to a conspicuous shorebird.

New Geosphere series: The St. Elias Erosion/Tectonics Project in Southern Alaska
GEOSPHERE has added a new themed issue to its roster: 'Neogene tectonics and climate-tectonic interactions in the southern Alaskan orogeny.' Interest in Alaskan tectonics has varied over time, propelled mostly by geologic hazards. In 1964, the great Alaskan earthquake focused attention on Alaska and was a major factor in the establishment of the concept of subduction in the early days of plate tectonics.

The human food connection: A new study reveals more about our relationship to food
Tucked away in Hartford, Conn., a Puerto Rican community is creating a tropical home away from home through cuisine that is so authentic it has caught the attention of scientists. David W. Taylor (University of Portland) and Gregory J. Anderson (University of Connecticut) took a close look at the fresh crops in the Puerto Rican markets of Hartford and uncovered evidence that gives new meaning to a phrase that food lovers have been using for years: home is in the kitchen.

Scholars propose new standards for gauging muscle decline in older adults
Sarcopenia -- the age-related loss of muscle mass and strength -- may put up to 50 percent of seniors at greater risk for disability, yet there is no consensus within the medical community for how this condition should be measured. However, a new collection of articles appearing in the Journals of Gerontology, Series A: Biological Sciences and Medical Sciences lays out an empirically derived set of criteria for diagnosing sarcopenia.

New technique will accelerate genetic characterization of photosynthesis
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. We do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism. A team developed a highly sophisticated tool that will transform the work of plant geneticists on this subject.
