Researchers uncover protein-based 'cancer signature'

Mon, 05/12/2016 - 1:59pm
A research team has investigated the expression of ribosomal proteins in a wide range of human tissues including tumors and discovered a cancer type specific signature. This “cancer signature” could potentially be used to predict the progression of the disease.

ALMA measures size of seeds of planets

Mon, 05/12/2016 - 1:59pm
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA), have for the first time, achieved a precise size measurement of small dust particles around a young star through radio-wave polarization. ALMA’s high sensitivity for detecting polarized radio waves made possible this important step in tracing the formation of planets around young stars.

Role of molecular modification in determining physical activity levels revealed

Mon, 05/12/2016 - 1:59pm
Researchers show modification of a gene product results in greater physical activity and reduced body weight in mice, thus boosting understanding of how physical activity is regulated at the cellular level in the nervous system.

Highly efficient genome engineering in flowering plants

Mon, 05/12/2016 - 1:59pm
Plant biologists have developed a genome editing method to knockout target genes in a model plant with high efficiency. The team reports a new CRISPR/Cas9 vector for the model plant that can strongly induce inheritable mutations. This method is expected to become a powerful molecular tool for genome engineering in various plant species.

Stress-hormone differences identified among gay men

Sat, 03/12/2016 - 8:45pm
Increased stigma and discrimination can affect circadian HPA-axis functioning, say researchers. The majority of previous studies have been conducted among white heterosexuals, with very little research examining HPA-axis functioning between different minorities. Individuals who identify as both sexual and racial minorities may experience increased stigma and discrimination that can affect this HPA-axis functioning. Now, researchers have examined differences in diurnal cortisol rhythm between young, self-identified, white gay men and black gay men.

Relationships between chemicals found on comets

Sat, 03/12/2016 - 8:45pm
A new study has revealed similarities and relationships between certain types of chemicals found on 30 different comets, which vary widely in their overall composition compared to one another. The research is part of ongoing investigations into these primordial bodies, which contain material largely unchanged from the birth of the solar system some 4.6 billion years ago.

Biomarker may predict which formerly treated cancer patients will develop highly fatal form of leukemia

Sat, 03/12/2016 - 8:45pm
Patients successfully treated for breast, colon and other cancers can go on to develop an often-fatal form of leukemia, sometimes years after completion of treatment, due to a genetic mutation leading to secondary malignancies known as therapy-related myeloid neoplasms (t-MNs).

After one dose of gene therapy, hemophilia B patients maintain near-normal levels of clotting factor

Sat, 03/12/2016 - 8:45pm
Researchers are reporting the highest and most sustained levels to date of an essential blood-clotting factor IX in patients with the inherited bleeding disorder hemophilia B. After receiving a single dose of an experimental gene therapy in a clinical trial, patients with hemophilia produced near-normal levels of clotting factor IX, allowing them to stop clotting factor infusions and to pursue normal activities of daily life without disabling bleeding episodes.

CD19-targeting CAR T-cell immunotherapy yields high responses in treatment-resistant CLL

Sat, 03/12/2016 - 8:45pm
In a small, early phase trial, a high percentage of patients who had exhausted most traditional treatments for chronic lymphocytic leukemia saw their tumors shrink or even disappear after an infusion of a highly targeted, experimental CAR T-cell immunotherapy.

Natural nomads, leatherback turtles opt to stay in place

Fri, 02/12/2016 - 8:29pm
Endangered leatherback sea turtles are known for their open-ocean migratory nature and nomadic foraging habits -- traveling thousands of miles. But a naturalist and his colleagues have discovered an area along the Mozambique coast that the turtles have made their permanent home, according to a study.

New aspect of atom mimicry for nanotechnology applications

Fri, 02/12/2016 - 8:20pm
In nanotechnology, control is key. Control over the arrangements and distances between nanoparticles can allow tailored interaction strengths so that properties can be harnessed in devices such as plasmonic sensors. Now researchers use dendrimers that mimic the electron valency of atoms and link them into arrays using molecules that coordinate with the dendrimer as they would form a covalent electron pair in their valence shell - "electron pair mimicry".

Exotic insulator may hold clue to key mystery of modern physics

Fri, 02/12/2016 - 8:08pm
Experiments using laser light and pieces of gray material the size of fingernail clippings may offer clues to a fundamental scientific riddle: What is the relationship between the everyday world of classical physics and the hidden quantum realm that obeys entirely different rules?
