Analogues of a natural product are drug candidates against malaria

Malaria is one of the most serious health problems worldwide, registering 200 million clinical cases and more than 600,000 attributable deaths per year, according to information from the World Health Organization in 2013. Given the emerging resistance to the standard treatment most widely used throughout the world, which is based on artemisinin and its analogs, there is a need for new antimalarial compounds.

Phenomenal fossil and detailed analysis reveal details about enigmatic fossil mammals

Mammals that lived during the time of the dinosaurs are often portrayed as innocuous, small-bodied creatures, scurrying under the feet of the huge reptiles. In reality, this wasn't the case, and a new fossil from Madagascar further underscores this point, revealing fascinating perspectives on the growing diversity of Mesozoic mammals. Vintana sertich had previously been described in a preliminary note in November of this year, but a new memoir in the Journal of Vertebrate Paleontology delves far deeper into the morphology and paleoecology of this amazing fossil animal.

Supplement could reduce heart disease risk in people of low birth weight

A simple supplement could be a safe and cost-effective way of reducing heart disease in individuals born with a low birth weight, suggests research from the University of Cambridge. The study, carried out in rats, also raises the possibility of developing a blood test to indicate how much damage there is in the aortas of these individuals.

New breast cancer classification based on epigenetics

Breast cancer is the most common in women. One in nine will suffer breast cancer over their lifetime. Progress in prevention and early detection, and the use of chemotherapy after surgery (adjuvant chemotherapy), have achieved significantly increase survival in this disease in the last ten years, but much remains to be done.

Breakthrough simplifies design of gels for food, cosmetics and biomedicine

Scientists at the University of Strathclyde and City University of New York have created methods that dramatically simplify the discovery of biological gels for food, cosmetics and biomedicine, as published in the journal Nature Chemistry.

Strathclyde's Dr Tell Tuttle and Professor Rein Ulijn, the director of nanoscience at City University New York's new advanced research centre who also holds a position at Strathclyde, believe their team's breakthrough dramatically simplifies discovery of functional gels that can be used in a wide range of applications.

Daclatasvir for hepatitis C: Added benefit not proven

The drug daclatasvir (trade name Daklinza) has been available since August 2014 for the treatment of adults with chronic hepatitis C (CHC) infection. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether this new drug offers an added benefit over the appropriate comparator therapy.

Disney Researchers use multiple photos to estimate lighting conditions of outdoor scenes

Techniques now used to reconstruct 3D models based on multiple photos of a building, object or scene can also be leveraged to automatically estimate illumination conditions depicted in a collection of photographs, scientists at Disney Research and Université Laval report.

Nuclear medicine treatment shows promise for cancer therapy

Reston, Va. (December 9, 2014) - Cancer therapy can be much more effective using a new way to customize nuclear medicine treatment, researchers say in the December 2014 issue of The Journal of Nuclear Medicine. The process could also be useful for other diseases that could benefit from targeted radiation.

Guidelines for treatment of Ebola patients are urgently needed

London, United Kingdom, December 9, 2014 - As the Ebola Virus Diseases (EVD) epidemic continues to rage in West Africa, infectious diseases experts call attention to the striking lack of treatment guidelines. With over 16,000 total cases and more than 500 new infections reported per week, and probable underreporting of both cases and fatalities, the medical community still does not have specific approved treatment in place for Ebola, according to an editorial published in the International Journal of Infectious Diseases.

With experience, people can tell bears apart

Studying the social interaction of bears through the use of camera traps and visual observations requires that humans be able to tell individuals apart. A study done using volunteers to study the vulnerable Andean bear indicates that people can learn to identify individual bears, given a little practice. The research, done by San Diego Zoo conservationists with international collaborators using photos spanning many years, also indicates that young bears usually retain many of their unique markings as they grow older.

German researchers propose better substances for treating the dengue virus

Researchers from Johannes Gutenberg University Mainz (JGU) and the Julius Maximilian University of Würzburg are proposing potential new active substances for treating the dengue virus. Just like Ebola, dengue fever is also caused by a virus for which there is currently no cure and no vaccine and can be fatal.

Immune function marker does not predict benefit of trastuzumab in HER-2+ breast cancer

JACKSONVILLE, Fla. -- A marker of immune function that predicts for better outcomes in patients treated with chemotherapy for triple negative breast cancer is also linked to improved prognosis in patients treated with chemotherapy for HER2-positive breast cancer.

Link between power lines and ill-health called into question

Several past studies have suggested that the magnetic fields created by phones, high-voltage power lines and other electrical equipment are harmful for humans.

Research first carried out in the 1970's and again subsequently, found an association between people living near overhead power lines and an increased risk of childhood leukaemia. Although some later studies have failed to find such a link, the International Agency for Research on Cancer has categorised low frequency magnetic fields as "possibly carcinogenic."

Drug developed at Pitt proves effective against antibiotic-resistant 'superbugs'

PITTSBURGH, Dec. 9, 2014 - A treatment pioneered at the University of Pittsburgh Center for Vaccine Research (CVR) is far more effective than traditional antibiotics at inhibiting the growth of drug-resistant bacteria, including so-called "superbugs" resistant to almost all existing antibiotics, which plague hospitals and nursing homes.

Can organic crops compete with industrial agriculture?

Berkeley -- A systematic overview of more than 100 studies comparing organic and conventional farming finds that the crop yields of organic agriculture are higher than previously thought. The study, conducted by researchers at the University of California, Berkeley, also found that certain practices could further shrink the productivity gap between organic crops and conventional farming.
