Scientists identify brain mechanism that drives our appetite for glucose-rich foods

Scientists have discovered a mechanism in the brain that may drive our appetite for foods rich in glucose and could lead to improved treatments for obesity.

Researchers freeze biological structures to illustrate DNA double-strand break process

Scientists from the Spanish National Cancer Research Centre, led by Guillermo Montoya, have developed a method for producing biological crystals that has allowed scientists to observe --for the first time-- DNA double chain breaks. They have also developed a computer simulation that makes this process, which lasts in the order of millionths of a second, visible to the human eye.

Study finds that disarray in methylation helps tumors adapt to changing circumstances

The genetic tumult within cancerous tumors is more than matched by the disorder in one of the mechanisms for switching cells' genes on and off, scientists at Dana-Farber Cancer Institute and the Broad Institute of MIT and Harvard report in a new study.

Researchers test new nanopore DNA sequencing technology to detect cause of antibiotic resistance

New nanopore DNA sequencing technology on a device the size of a USB stick could be used to diagnose infection - according to new research from the University of East Anglia and Public Health England.

Researchers develop nanomimics of host cell membranes that trick malaria parasites

Malaria parasites invade human red blood cells, they then disrupt them and infect others. Researchers at the University of Basel and the Swiss Tropical and Public Health Institute have now developed so-called nanomimics of host cell membranes that trick the parasites. This could lead to novel treatment and vaccination strategies in the fight against malaria and other infectious diseases.

BAZ2A protein directly influences the aggressiveness of prostate cancer

A protein that influences the epigenetic characteristics of tumor cells is directly linked to the grade of malignancy of prostate cancer. This key discovery has been made by a team of scientists from the German Cancer Research Center, the University of Zurich, Hamburg-Eppendorf University Hospital, Heidelberg University, and other institutes in a study of 7,700 samples of tumor tissue.

Johns Hopkins researchers discover new way to treat triple-negative breast cancer

Triple-negative breast cancer is as bad as it sounds. The cells that form these tumors lack three proteins that would make the cancer respond to powerful, customized treatments. Instead, doctors are left with treating these patients with traditional chemotherapy drugs that only show long-term effectiveness in 20 percent of women with triple-negative breast cancer.

Scientists identify brain mechanisms that turn unpleasant experiences into long-lasting memories

We know that everyday events can be easy to forget, but dangerous experiences that trigger fear can remain engraved in the brain for years. Now, scientists from New York University and Japan's RIKEN Brain Science Institute have added to our understanding how this occurs.

Case Western Reserve selected to lead $27.3 million international effort to identify causes of SUDEP

Case Western Reserve is one of two universities in the country selected to lead a $27.3 million international effort to identify the causes of a mysterious and deadly phenomenon that strikes people with epilepsy without warning.

Triple hormone reduces body weight, improves insulin sensitivity

Recently, the researchers had constructed several single molecules with dual hormone action. Now, for the first time, the researchers succeeded in designing a substance that combines three metabolically active hormone components (GLP-1, GIP and glucagon) and offers unmatched potency to fight metabolic diseases in pre-clinical trials.

Study shows seasonal flu vaccines may protect individuals against many different viruses

Seasonal flu vaccines may protect individuals not only against the strains of flu they contain but also against many additional types, according to a study published this week in mBio, the online open-access journal of the American Society for Microbiology.

MD Anderson study sheds light on miR569 gene

A genetic misfire called the 3q26.2 amplicon can cause real havoc. In fact, it is among the most frequent chromosomal aberrations seen in many cancers, including ovarian and breast cancers.

Study: Injectable 3D vaccines could help prevent cancer, infectious disease

One of the reasons cancer is so deadly is that it can evade attack from the body's immune system, which allows tumors to flourish and spread. Scientists can try to induce the immune system, known as immunotherapy, to go into attack mode to fight cancer and to build long lasting immune resistance to cancer cells.

McMaster University researchers identify hormone that contributes to obesity, diabetes

Researchers from McMaster University have identified an important hormone that is elevated in obese people and contributes to obesity and diabetes by inhibiting brown fat activity.

Screening system spots cancerous changes invisible to sequencing

A technique that can identify causes of cancer invisible to genetic sequencing has uncovered large sets of previously unknown pancreatic cancer genes. It is hoped that this study will boost research into a disease that is still poorly understood and for which five-year survival rates have stood at around 5 per cent for the past four decades.

Findings open new avenues for research to predict risk of therapy-related AML

For a small percentage of cancer patients, treatment aimed at curing the disease leads to a form of leukemia with a poor prognosis. Conventional thinking goes that chemotherapy and radiation therapy induce a barrage of damaging genetic mutations that kill cancer cells yet inadvertently spur the development of acute myeloid leukemia (AML), a blood cancer.

Study highlights causes of postpartum disorders in new mothers

In the days shortly after giving birth, most mothers experience a period of increased calmness and decreased stress responses, but around 20% of mothers experience anxiety. Some women may become depressed, and around one in a thousand can develop psychosis. The latest evidence indicates that these distressing responses to motherhood are still poorly understood, but that animal research could provide valuable clues to their causes.
