SAN ANTONIO – Patients with early-stage, node-negative, hormone receptor (HR)-positive, HER2- negative breast cancer who have a high risk of recurrence based on the OncotypeDX genomic test had better outcomes when treated with adjuvant anthracycline- plus taxane-based chemotherapy regimens compared with those receiving adjuvant taxane-based chemotherapy regimens alone, according to results presented at the San Antonio Breast Cancer Symposium (SABCS), held December 10-13, 2024. “HR-positive, HER2-negative is the most common type of breast cancer in the United States and we frequently need to decide whether or not adjuvant chemotherapy ...

SAN ANTONIO – The ZEST clinical trial, designed to evaluate niraparib (Zejula) for the prevention of breast cancer recurrence in patients with circulating tumor DNA (ctDNA), failed to accrue enough patients positive for ctDNA, according to results presented at the San Antonio Breast Cancer Symposium (SABCS), held December 10-13, 2024. As some of the lessons learned from this trial, investigators suggest beginning ctDNA testing during treatment rather than waiting for treatment completion as done in ZEST, and including patients with high- risk ...

SAN ANTONIO – A machine learning (ML) model incorporating both clinical and genomic factors outperformed models based solely on either clinical or genomic data in predicting which patients with hormone receptor (HR)-positive, HER2-negative metastatic breast cancer would have better outcomes from adding CDK4/6 inhibitors to endocrine therapy as first-line treatment, according to results presented at the San Antonio Breast Cancer Symposium (SABCS), held December 10-13, 2024. While the use of CDK4/6 inhibitors combined with endocrine therapy have significantly improved outcomes in patients with HR-positive, ...

More than six million Americans are affected by Alzheimer’s disease, a form of dementia marked by accumulation of amyloid-β within the brain. Amyloid-β is a relatively small protein that forms toxic plaques in the brain contributing to the harmful effects of Alzheimer's disease. Another protein, hyperphosphorylated tau (pTau), also accumulates as toxic neurofibrillary tangles. Together, amyloid-β plaques and pTau tangles result in brain damage, neuroinflammation and ultimately brain death. Gene expression studies have already identified ...

(Carlisle, Pa.) — A new study in the journal Scientific Reports offers a rare glimmer of hope in the face of climate change, suggesting glacial rivers and lakes may play a crucial role in mitigating the effects of  methane, a powerful greenhouse gas that recent studies have shown emerging as glaciers melt in warming global temperatures. This new study, led by Dickinson College Associate Professor of Environmental Studies Kristin Strock, looked at what happens when glaciers melt and release trapped methane, a potent greenhouse gas that contributes to climate change. Strock, a 2019 National Geographic Explorer, led an all-female team of researchers ...

Over the last decade, the global market for plant-based beverages has seen remarkable growth, with oat, almond, soy and rice drinks emerging as popular alternatives to cow’s milk in coffee and oatmeal during this time. One of the likely reasons for millions of liters of plant-based drinks ending up in the shopping baskets of consumers is that their climate footprint is often lower than that of cow’s milk. But consumers would be mistaken if they considered plant-based beverages healthier than cow’s milk. This is highlighted in a new study conducted by the University of Copenhagen in collaboration with the University ...

The findings were published today by the journal Nature ...

Also known as Virgo A or NGC 4486, M87 is the brightest object in the Virgo cluster of galaxies, the largest gravitationally bound type of structure in the universe. It came to fame in April 2019 after scientists from EHT released the first image of a black hole in its center. Led by the EHT multi wavelength working group, a study published in Astronomy and Astrophysics Journal presents the data from the second EHT observational campaign conducted in April 2018, involving over 25 terrestrial and orbital telescopes. The authors report the first observation of a high-energy gamma-ray flare in over a decade from the supermassive black hole M87, based on nearly ...

A new database of African hippo populations has revealed huge gaps in our knowledge of where the megaherbivores live and thrive, with populations fragmented and reliant on protected areas. Hippos are classified as “vulnerable to extinction” by the International Union for the Conservation of Nature (IUCN) Red List and have been called the “neglected megafauna”, with a lack of scientific attention and much less research into their lives and habitats than other large mammals. University of Leeds School of Biology Postgraduate Researcher Hannah Lacy ...

Sometimes, moving just a few inches can go a long way. Osaka Metropolitan University researchers have developed a promising technique for head and neck reconstruction that shifts the placement of transferred tissue with blood vessels attached, offering a safer, faster option for patients with complex tissue defects, especially those at high risk. Head and neck reconstruction plays a crucial role in the treatment of patients with head and neck cancer. The goal is to preserve functions vital for breathing, ...

Precursor lesions of pancreatic cancer are very difficult to characterise with magnetic resonance imaging (MRI). But now, in a new study, researchers led by Noam Shemesh and Carlos Bilreiro – respectively head of the Preclinical MRI lab at Champalimaud Research and a doctor at the Champalimaud Clinical Centre’s Radiology Department – have shown, for the first time, that a particular form of MRI, called Diffusion Tensor Imaging (DTI), is capable of robustly detecting pre-malignant lesions in the pancreas. ...

New research from Karolinska Institutet in Sweden highlights the possibility of screening people with type 2 diabetes for liver damage at the same time as they undergo screening for eye disease. The study is published in Lancet Gastroenterology and Hepatology. More than half of all people with type 2 diabetes have steatotic (or fatty) liver disease, but most do not realise it since liver disease rarely causes any symptoms in the earlier stages. Over time, liver fibrosis can develop. This is a type of scarring of the liver that can lead to cirrhosis or liver cancer in some patients. International ...

New research finds that giraffes much prefer flat terrain and do not traverse slopes of more than 20°, which severely limits the areas in, and outside, protected reserves they can access. The findings, which is are yet to be published, will be presented at the British Ecological Society’s (BES) Annual meeting in Liverpool on the 13th December. A new study analysing the movements of 33 GPS collared giraffes in South Africa has found that they avoid steep terrain and are unable to navigate slopes with a gradient of more than 20° , most likely due to the energy required and the risk of falling. The researchers from the University of Manchester ...

1. A research team from NIMS and UTokyo has proposed and demonstrated that the transverse magneto-thermoelectric conversion in magnetic materials can be utilized with much higher performance than previously by developing artificial materials comprising alternately and obliquely stacked multilayers of a magnetic metal and semiconductor. 2. When a temperature gradient is applied to a magnetic conductor, a charge current is generated in a direction orthogonal to directions of both temperature gradient and magnetization of the magnetic conductor. This transverse magneto-thermoelectric phenomenon, ...

-With images-   Durham University scientists have made a groundbreaking discovery in marine geoscience, revealing unprecedented insights into the dynamics of Earth’s longest runout sediment flows.   By using seabed seismographs placed safely outside the destructive paths of powerful underwater avalanches of sediment, researchers have successfully monitored turbidity currents—a natural phenomenon that shapes deep-sea landscapes, damages telecommunication cables, and transports large quantities of sediment and organic carbon to the ocean floor.   The study recorded two massive turbidity ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific controversy.  Taking a fresh approach at an old problem, Sawsan Wehbi, a doctoral student in the Genetics Graduate Interdisciplinary Program at the University of Arizona, discovered strong evidence that the textbook version of how the universal genetic code evolved needs revision. Wehbi is the first author of a study published in the journal PNAS suggesting the order with which amino acids – the code's building blocks –  were recruited is at odds with ...

CHAMPAIGN, Ill. — The Midwest played a central role in the growth of Black freedom movements in the 20th century. It was a key site for incubating and expanding the ideas of political activist Marcus Garvey, not only in the U.S., but globally, said University of Illinois Urbana-Champaign professor of African American studies and history Erik S. McDuffie. McDuffie examined the influence of Garvey and the importance of the Midwest in the growth of Black internationalism and radicalism in his new book, “The Second Battle for Africa: Garveyism, the U.S. Heartland and Global Black Freedom.” McDuffie ...

In most research labs, the scientists are on the same page about why they’re pursuing a research project. But the Rubin Lab at HHMI's Janelia Research Campus isn’t an ordinary research lab. The lab is examining how aggression affects vision in female fruit flies, but Janelia Senior Group Leader Gerry Rubin doesn’t care too much about the specific answer. Instead, he simply wants to see if the neuroscience research tools that he spent the last decade building are adequate to uncover the underlying mechanisms at play.    Postdoc Katie Schretter, on the other hand, is interested in understanding how neurons in the fly brain ...
