Olfactory receptors: New molecular targets detected in colorectal cancer cells

Science Daily - Thu, 23/03/2017 - 6:13pm
Growth of colorectal cancer cells can be inhibited with the odorant troenan, report scientists. The researchers detected the olfactory receptor OR51B4 in tumor cells taken from the rectum and colon cancer cell lines. They analyzed which odorant activates the receptor and in what way the activation affects the cells.

Promising results obtained with a new electrocatalyst that reduces the need for platinum

Science Daily - Thu, 23/03/2017 - 6:13pm
A group researchers has developed a manufacturing method for electrocatalysts that only uses one hundredth of the amount of platinum generally used in commercial products. The activity achieved using the new material is similar to that of commercial electrocatalysts. The method is based on the special characteristics of carbon nanotubes.

Stress may protect, at least in bacteria

Science Daily - Thu, 23/03/2017 - 6:13pm
Antibiotics harm bacteria and stress them. Trimethoprim, an antibiotic, inhibits the growth of the bacterium Escherichia coli and induces a stress response. This response also protects the bacterium from subsequent deadly damage from acid. Antibiotics can therefore increase the survival chances of bacteria under certain conditions.

Encouraging results for patients with aggressive brain cancer

Science Daily - Thu, 23/03/2017 - 6:13pm
Patients diagnosed with a glioblastoma, and who undergo current standard treatment, have a median survival of 16 months. Based on recent information on the mechanisms of chemotherapy, a team of researchers developed a new clinical approach overcome treatment resistance that increased the median survival to 22 months -- bringing much needed hope to those affected by this aggressive disease.

Senate Votes To Kill FCC's Broadband Privacy Rules

Slashdot - Thu, 23/03/2017 - 5:40pm
The Senate voted 50-48 along party lines Thursday to repeal an Obama-era law that requires internet service providers to obtain permission before tracking what customers look at online and selling that information to other companies. PCWorld adds: The Senate's 50-48 vote Thursday on a resolution of disapproval would roll back Federal Communications Commission rules requiring broadband providers to receive opt-in customer permission to share sensitive personal information, including web-browsing history, geolocation, and financial details with third parties. The FCC approved the regulations just five months ago. Thursday's vote was largely along party lines, with Republicans voting to kill the FCC's privacy rules and Democrats voting to keep them. The Senate's resolution, which now heads to the House of Representatives for consideration, would allow broadband providers to collect and sell a "gold mine of data" about customers, said Senator Bill Nelson, a Florida Democrat. Kate Tummarello, writing for EFF: [This] would be a crushing loss for online privacy. ISPs act as gatekeepers to the Internet, giving them incredible access to records of what you do online. They shouldn't be able to profit off of the information about what you search for, read about, purchase, and more without your consent. We can still kill this in the House: call your lawmakers today and tell them to protect your privacy from your ISP.

Scientists reveal hidden structures in bacterial DNA

Science Daily - Thu, 23/03/2017 - 5:25pm
Researchers have described the 3D structure of the genome in the extremely small bacteria Mycoplasma pneumoniae. They discovered previously unknown arrangements of DNA within this tiny bacteria, which are also found in larger cells. Their findings suggest that this type of organization is a universal feature of living cells.

Australia Shelves Copyright Safe Harbor For Google, Facebook

Slashdot - Thu, 23/03/2017 - 5:20pm
In a surprise setback for companies such as Google and Facebook that leverage user-generated content, Australia has dropped plans to extend its copyright safe harbor provisions. From a report: In a blow to Google, Facebook and others, the government dropped the amendments before they were due to be introduced to parliament yesterday. That came as a big surprise, particularly as Prime Minister Malcolm Turnbull had given the proposals his seal of approval just last week. "Provisions relating to safe harbor were removed from the bill before its introduction to enable the government to further consider feedback received on this proposal whilst not delaying the passage of other important reforms," Communications Minister Mitch Fifield said in a statement. There can be little doubt that intense lobbying from entertainment industry groups played their part, with a series of articles published in News Corp-owned The Australian piling on the pressure in favor of rightsholders.

Statins may provide treatment alternative for chronic liver disease

Science Daily - Thu, 23/03/2017 - 5:03pm
Statin drugs are widely used to manage high cholesterol and reduce the risk of cardiovascular disease. But in a new review of more than 50 studies, researchers cite reductions in liver inflammation and improvements in other related factors as reasons why statins make good candidates for treating chronic liver disease.

New study shows circular RNA can encode for proteins

Science Daily - Thu, 23/03/2017 - 4:55pm
Scientists have discovered a protein-encoding function for circular RNA, a form of RNA until now considered non-coding. This kind of RNA molecule is highly active in brain cells. By identifying the function of circRNAs, the research helps advance our understanding of molecular biology, and can be helpful in understanding aging or neuro-degenerative diseases.

Limiting protein reduces post-heart attack injury in mice

Science Daily - Thu, 23/03/2017 - 4:55pm
According to the Centers for Disease Control and Prevention, approximately 735,000 Americans experience a heart attack each year. Opening a blocked coronary artery to restore blood flow to the heart prevents sudden cardiac death. However, doing so also triggers cardiac damage through oxidative stress and inflammation, which eventually can lead to heart failure. Researchers have identified a protein that can be targeted to decrease post-heart attack injury and prevent heart failure in a mouse model.

Virtual environment education reduces anxiety prior to radiation therapy

Science Daily - Thu, 23/03/2017 - 4:54pm
Radiation therapists and physicians know that education can reduce anxiety before radiation treatment but lack a standardized tool. In an effort to solve this problem, a multidisciplinary team conducted a pilot study to see if a virtual environment education program could reduce some of the anxiety their patients face.
