Patients with stage 2 or stage 3 triple-negative breast cancer (TNBC) who had a pathologic complete response (pCR) after presurgery chemotherapy had increased event-free and overall survival compared with those who had more than minimal residual invasive disease at surgery following presurgery chemotherapy, according to results from the randomized phase II CALGB/Alliance 40603 clinical trial presented at the 2015 San Antonio Breast Cancer Symposium, held Dec. 8-12
An ongoing phase IIR/III clinical trial presented at the 2015 San Antonio Breast Cancer Symposium seeks to answer an important question in the treatment of early metastatic breast cancer: Should surgery or stereotactic body radiation be used to “weed the garden” of a few sites of metastasis while continuing treatment that may still be controlling the initial tumor? read more

The Ceratopsia family is growing again. Researchers have described a new species of plant-eating dinosaur, Hualianceratops wucaiwanensis , that stood on its hind feet and was about the size of a spaniel
Prior to the rise of modern day mammalian carnivores (lions and tigers and bears, as well as weasels, raccoons, wolves and other members of the order Carnivora), North America was dominated by a now extinct group of mammalian carnivores – the hyaenodontids. While fossils of hyaenodontids are relatively common from the early Eocene (between 50 and 55 million years ago), most of these are specimens of teeth
For the first time, a litter of puppies was born by in vitro fertilization, thanks to work by Cornell University researchers. read more
Heart medication taken in combination with chemotherapy reduces the risk of serious cardiovascular damage in patients with early-stage breast cancer, according to results from a new landmark clinical trial.
Explosives detection is important for ensuring the safety of public spaces, transportation and water systems, but it can be challenging to carry out. Now scientists report in the journal ACS Nano a new step toward a more efficient monitoring method that uses quantum dots to quickly sniff out and identify five dangerous compounds, including the powerful explosive hidden in ‘shoe bomber’ Richard Reid’s footwear
A new test for detecting multiple explosives simultaneously has been developed by UCL scientists. The proof-of-concept sensor is designed to quickly identify and quantify five commonly used explosives in solution to help track toxic contamination in waste water and improve the safety of public spaces. read more
A new study involving UT Dallas researchers shows that vagus nerve stimulation (VNS) technology could help improve the lives of hundreds of thousands of people who suffer weakness and paralysis caused by strokes. read more
Climate scientists at the National Center for Atmospheric Research (NCAR) present evidence in a new study that they can predict whether the Arctic sea ice that forms in the winter will grow, shrink, or hold its own over the next several years.
Porcine Reproductive and Respiratory Syndrome (PRRS) virus was first detected in the U.S. in 1987.
@OrbitalATK’s #Cygnus spacecraft is moving toward its capture point at the International Space Station as astronauts maneuver the Canadian-built robotic arm to reach out for dramatic vehicle grappling on Dec. 9, 2015
Emissions controls on coal-fired power plants are making a difference in reducing exposure of mercury to people, especially in the western Maryland community. A study of air quality from the University of Maryland Center for Environmental Science found that levels of mercury in the air from power plant emissions dropped more than half over a 10-year period, coinciding with stricter pollution controls
The temple of Angkor Wat was much larger and more complex than previously thought, University of Sydney archaeologists have discovered. read more
Biologists at UC San Diego have found that a method they developed to identify and characterize new antibiotics can be employed to screen natural products quickly for compounds capable of controlling antibiotic resistant bacteria. read more
The spectacular aftermath of a 360 million year old cosmic collision is revealed in great detail in new images from ESO’s Very Large Telescope at the Paranal Observatory.
The train to Tsukuba, Japan often carries workers with briefcases and travelers with overnight bags, but recently a group of scientists took an unusual bit of luggage on board: a suitcase with an ultrahigh vacuum chamber to store air-sensitive clusters of platinum metal.
Cancer Research UK scientists have found that five in six women with increased risk of breast cancer turn down drugs likely to prevent the disease, according to research published in Annals of Oncology . read more
It is well documented that a healthy diet and exercise are key in cancer prevention and management, but the exact mechanism hasn’t been clear. Now, Yale Cancer Center researchers have found an explanation in the tiny protective ends of chromosomes called telomeres.
