3D printed templates of filament networks can improve function of engineered living tissues

Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient's own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow.

Study illuminates key step in the journey of inflammation-producing immune cells

Like detectives seeking footprints and other clues on a television "whodunit," science can also benefit from analyzing the tracks of important players in the body's molecular landscape. Klaus Ley, M.D., a scientist at the La Jolla Institute for Allergy & Immunology, has done just that and illuminated a key step in the journey of inflammation-producing immune cells.

Researchers map significant portion of functional sequences of mouse genome

Popularly dubbed "the book of life," the human genome is extraordinarily difficult to read. But without full knowledge of its grammar and syntax, the genome's 2.9 billion base-pairs of adenine and thymine, cytosine and guanine provide limited insights into humanity's underlying genetics.

Researchers demonstrate power of single-molecule sequencing

The next "next-gen" technology in genome sequencing has gotten a major boost.

Study illustrates novel mechanical transduction properties of hematopoietic stem cells

A recent study led by Andrew Puca, Ph.D. under the supervision and direction of Antonio Giordano, M.D., Ph.D. set out to illustrate novel mechanical transduction properties of Hematopoietic Stem Cells in relation to defining the expression of humoral factors by facilitating paracrine/autocrine signalling via microgravity.

New toxicology testing method requires lesser number of fish

A new way of testing the safety of natural and synthetic chemicals has been developed by scientists with funding from the Biotechnology and Biological Sciences Research Council (BBSRC). Their research, published today in the journal Ecotoxicology, could reduce the number of fish needed to test the toxicity of a range of chemicals including pharmaceuticals and environmental pollutants.

Big challenges from antibiotic resistant bacteria

Antibiotic resistant bacteria are increasing and spreading at an alarming speed. The bacterial evolution is overwhelming our antibiotic defense. More and more bacteria are becoming resistant to antibiotics resulting in fatal consequences for millions of people. We need common action and responsibility for the development of new effective antibiotics and to stop antibiotic misuse.

Severe sleep loss jolts the immune system into action

Severe sleep loss jolts the immune system into action, reflecting the same type of immediate response shown during exposure to stress, a new study reports.

Genetic mutation that creates Ewing's sarcoma leads to high levels of protein EYA3

Ewing's sarcoma is a bone cancer commonly diagnosed in about 250 U.S. teenagers per year. If early chemotherapy is effective, improvement can be durable. But for children and teens who respond poorly to a first attempt at chemotherapy or if the disease spreads, long-term survival can be less than 10 percent.

Rapamycin enhances learning and memory in young mice

Cognitive skills such as learning and memory diminish with age in everyone, and the drop-off is steepest in Alzheimer's disease. Texas scientists seeking a way to prevent this decline reported exciting results this week with a drug that has Polynesian roots.

Bees help understand connection between taste perception and metabolic syndromes

Scientists at Arizona State University have discovered that honey bees may teach us about basic connections between taste perception and metabolic disorders in humans. By experimenting with honey bee genetics, researchers have identified connections between sugar sensitivity, diabetic physiology and carbohydrate metabolism. Bees and humans may partially share these connections.

Blocking bombesin/GRP receptor improves survival in sepsis animal models

Septic shock is the most severe outcome associated with pathogen infection in the bloodstream. It is a life-threatening condition invariably leading to multiple organ dysfunctions. Currently, septic shock is one of the most frequent causes of death in intensive care units worldwide.

Study details canonical Wnt signaling pathway

Many lung cancers are driven by mutations in the epidermal growth-factor receptor (EGFR), and so it makes sense that many successful modern treatments block EGFR activity. Unfortunately, cancers inevitably evolve around EGFR inhibition, and patients with lung cancers eventually relapse.

Researchers discover new gene mutations associated with megalencephaly

A research team led by Seattle Children's Research Institute has discovered new gene mutations associated with markedly enlarged brain size, or megalencephaly.

FOXO1 gene may play an important role in pathological mechanisms of Parkinson's

A recent study led by researchers at Boston University School of Medicine (BUSM) revealed that the FOXO1 gene may play an important role in the pathological mechanisms of Parkinson's disease.

Association between SCC and cutaneous HPV types

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida, the German Cancer Research Center in Heidelberg, and the International Agency for Research on Cancer in Lyon, France, conducted a case control study and found associations between having antibodies to certain types of cutaneous human papillomavirus (HPV) and a kind of skin cancer called squamous cell carcinoma (SCC).

Scientists successfully tag serotonin transporter to track movements of single molecules

In a process akin to belling an infinitesimal cat, scientists have managed to tag a protein that regulates the neurotransmitter serotonin with tiny fluorescent beads, allowing them to track the movements of single molecules for the first time.

Researchers develop first real-time, brain-scanning speller

Researchers have come up with a device that may enable people who are completely unable to speak or move at all to nevertheless manage unscripted back-and-forth conversation. The key to such silent and still communication is the first real-time, brain-scanning speller, according to the report published online on June 28 in Current Biology, a Cell Press publication.

UMass Amherst biochemist receives NIH grant to map molecular structure of bacterial needle

Biochemist Alejandro Heuck at the University of Massachusetts Amherst recently received a five-year, $950,000 grant from the National Institutes of Health to map the molecular structure of a needle-like tool used by deadly bacteria to drill holes in mammalian cell walls.

Blindsight in monkeys is available in everyday environments

The visual information from eyes is sent into the brain unconsciously even if you are not aware. One of examples of unconscious seeing is a phenomenon of "blindsight" [Subjects have no awareness, but their brains can see] in subjects with visual impairment, caused by the damage of a part of the brain called the visual cortex.
