One avocado a day helps lower 'bad' cholesterol for heart healthy benefits

Move over, apples — new research from Penn State suggests that eating one avocado a day may help keep “bad cholesterol” at bay. According to the researchers, bad cholesterol can refer to both oxidized low-density lipoprotein (LDL) and small, dense LDL particles. In a randomized, controlled feeding study, the researchers […]

Signaling waves determine embryonic fates

Timing is everything for young cells waiting to determine their identities. Research by Rice University bioscientist Aryeh Warmflash and graduate student Sapna Chhabra shows homogenous colonies of human embryonic stem cells use dynamic molecular signaling waves that pass from cell to cell and trigger them to differentiate. Once prompted, the cells begin to organize […]

Crimped or straight? Lung fiber shape influences elasticity

Take a deep breath. Now exhale. Congratulations! You’ve just done something completely ordinary, yet so mysterious that scientists still don’t know everything about it. How oxygen and carbon dioxide enter and leave the bloodstream is well known, but scientists are just beginning to understand what happens to respiratory tissues as […]

Researchers Explore Spinal Discs' Early Response to Injury and Ways to Improve It

Researchers may have found a way to press pause on spinal disc injuries, giving doctors more time to treat them before worse issues develop. The Penn Medicine-led team discovered that cells in the outer region of spinal discs become stressed and kick off a subpar healing process after injuries, which […]

Consuming alcohol leads to epigenetic changes in brain memory centers

Triggers in everyday life such as running into a former drinking buddy, walking by a once- familiar bar, and attending social gatherings can all cause recovering alcoholics to “fall off the wagon.” About 40 to 60 percent of people who have gone through treatment for substance abuse will experience some […]

Clues to improve cancer immunotherapy revealed

Cancer immunotherapy drugs trigger the body’s immune system to attack tumors and have revolutionized the treatment of certain cancers, such as lymphoma, lung cancer, and melanoma. Yet, while some patients respond well to the drugs, others don’t respond at all. Cancer immunologists want to change that. A new study by […]

Autism: Origin Story

First evidence of immune response targeting brain cells in autism. Autism spectrum disorders affect one in 59 American children by age eight. With no known quantitative biological features, autism diagnoses are currently based on expert assessments of behavioral symptoms, including impaired social and communication skills, repetitive behaviors and restricted interests. […]

A New Actor in Cancer Immunity

The immune system must strike an exquisite balance between vanquishing infections and cancer, while at the same time restraining its activity to avoid inadvertently attacking the body’s healthy tissues and organs. This balancing feat is accomplished by a host of regulatory genes that calibrate the immune response. When this calibration […]

Advancing Early Cancer Detection Methods

An interdepartmental team at the University of Michigan obtains a prestigious NIH grant that will support an advanced imaging strategy to improve methods for early cancer detection. Worldwide, the incidence of cancer is steadily growing. Research has shown time and time again that this rise is often connected to the […]

Zebrafish discovery throws new light on human hearing disorders

A study of the genetic make-up of zebrafish has provided brand new insights into the cause of congenital hearing disorders in humans. A team including scientists from Cardiff University has identified how specific genes can dictate the patterns of the tiny cells – so-called hair cells – within our ears […]

Study finds beta blockers ineffective in stopping COPD flare-ups

Chronic Obstructive Pulmonary Disease (COPD), which includes lung diseases such as emphysema and asthma, is the third leading cause of death of people worldwide. COPD patients can experience exacerbations, or intense “flare-ups,” of their conditions leading to hospitalization, breathing tube intubation and even death. A new study co-led by University of Minnesota School of […]

Scientists found a virus that could be causing liver cancer in cats

Cancer is a terrible disease, affecting humans and animals. Its exact causes and mechanism is still poorly understood, but in some cases it can be triggered by a virus. For example, now scientists from The University of Sydney found that a virus may be causing liver cancer in companion cats. […]

Biologists build proteins that avoid crosstalk with existing molecules

Inside a living cell, many important messages are communicated via interactions between proteins. For these signals to be accurately relayed, each protein must interact only with its specific partner, avoiding unwanted crosstalk with any similar proteins. A new MIT study sheds light on how cells are able to prevent crosstalk […]

New study reveals why breast cancer spreads to the brain

Most cancers kill because tumor cells spread beyond the primary site to invade other organs. Now, a USC study of brain-invading breast cancer cells circulating in the blood reveals they have a molecular signature indicating specific organ preferences. The findings, which appeared in Cancer Discovery, help explain how tumor cells […]

Scientists pioneer new way of finding cancer-causing germs

Scientists at the University of East Anglia are pioneering a new way of finding the bacteria and viruses associated with cancer. Some infections have already been linked with cancers including stomach cancer and cervical cancer. New research published in Genome Biology shows how genomic data collected from tumours could be sequenced […]

Sequencing Plays Role in Treating High Risk Pediatric Brain Tumors

They’re among the most ruthless opponents for pediatric oncologists: brain tumors that can’t be surgically removed or that resist standard therapies. Doctors have limited weapons to fight them, contributing to why brain cancer is still the leading cause of cancer-related death in children. But some institutions are re-thinking their approach. […]

A ‘thoughtful’ workout goes beyond physical benefits

Running and lifting weights might be a crucial step in helping your body delay the effects of aging, but those exercises may be only part of the story. In a new article published in Psychological Bulletin, a University of Georgia researcher found that the type of activity you choose may also have […]

Research identifies earlier origin of neural crest cells

Neural crest cells — embryonic cells in vertebrates that travel throughout the body and generate many cell types — have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest stages of embryonic development. But the capacity of neural crest cells to […]

Yale Cancer Center scientists build genomic research platform to help treat cervical cancer

Yale Cancer Center scientists have built a powerful genomic research platform to study cervical cancer, a disease that often is untreatable if it progresses after surgery or primary chemo-radiation treatment. The work is described in a study published in the Proceedings of the National Academy of Sciences (PNAS). “We have identified […]

New organelle that helps prevent cancer discovered inside our cells

Scientists at the University of Virginia School of Medicine have discovered a strange new organelle inside our cells that helps to prevent cancer by ensuring that genetic material is sorted correctly as cells divide. The researchers have connected problems with the organelle (a subcellular structure) to a subset of breast cancer […]

High blood pressure at maximal exercise may signal good fitness

Is it dangerous to have high blood pressure when exercising? “It depends”, is the answer from a newly published study. One important parameter used to give a prognosis or diagnosis in several conditions is blood pressure during exercise. A new study led by LiU scientist Kristofer Hedman shows that high […]

New study may have the reason why heart medication gives muscle pain

A study from McMaster has found a potential mechanism explaining why some people who take drugs to lower their cholesterol develop sore, aching muscles. The use of statin drugs to significantly lower cholesterol, and ultimately reduce the risk of cardiovascular disease, has become widespread and large-scale studies suggest that nearly […]
