President Trump and first lady test positive for COVID-19

President Donald Trump and first lady Melania Trump have tested positive for the coronavirus, he said Friday. The positive test comes a month until the election and after the president has spent the year largely downplaying the threat of the virus.

Why do people respond differently to the same drug?

Scientists at Scripps Research have comprehensively mapped how a key class of proteins within cells regulates signals coming in from cell surface receptors.

Laundry lint can cause significant tissue damage within marine mussels

Microscopic fibers created during the laundry cycle can cause damage to the gills, liver and DNA of marine species, according to new research.

Researchers discover a rare genetic form of dementia

A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain—which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer's Disease—that could be targeted for new therapies. The study was published today in Science.

15-year trend persists in disparate insulin pump use in children

Insulin pumps are widely used in the management of type 1 diabetes (T1D) and reviews have shown insulin pump therapy to be associated with improved glycemic control, fewer severe hypoglycemia events, and improved quality of life. Yet, non-Hispanic white children (NHW) are more than twice as likely as non-Hispanic Black children (NHB) to use this technology.

Bright light bars big-eyed birds from human-altered landscapes

New research shows the glaring light in human-altered landscapes, such as livestock pastures and crop fields, can act as a barrier to big-eyed birds, potentially contributing to their decline.

Researchers unveil sensor that rapidly detects COVID-19 infection

One feature of the COVID-19 virus that makes it so difficult to contain is that it can be easily spread to others by a person who has yet to show any signs of infection. The carrier of the virus might feel perfectly well and go about their daily business—taking the virus with them to work, to the home of a family member, or to public gatherings.

Researchers test brain stimulation in zero gravity

"It's exciting. I love this stuff!" said Bashar Badran, Ph.D. "This is so fun."

Research may curb economic losses to power plants after earthquakes

Sitting atop power transformers are wavy shaped bushing systems that play a critical role in supplying communities with electricity. However, these objects are also susceptible to breaking during earthquakes. Once damaged, bushings can cause widespread outages and burden the state with expensive repairs.

Vaccine opposition online uniting around 'civil liberties' argument

Anti-vaccination discourse on Facebook increased in volume over the last decade, coalescing around the argument that refusing to vaccinate is a civil right, according to a study published today in the American Journal of Public Health. This finding could have serious public health implications as vaccine opponents who unite around a single argument could quickly mobilize into a political movement able to lobby state lawmakers for vaccine exemptions, the researchers say.

Are organ transplant recipients at greater risk of death from COVID-19?

A new study, published in Transplantation, finds that risk of death from COVID-19 in organ transplant recipients may be based upon how the patient was treated.

Tool helps clear biases from computer vision

Researchers at Princeton University have developed a tool that flags potential biases in sets of images used to train artificial intelligence (AI) systems. The work is part of a larger effort to remedy and prevent the biases that have crept into AI systems that influence everything from credit services to courtroom sentencing programs.

Influence of bots on spreading vaccine information not as big as you think

The influence of bots on vaccine-related discussions on social media is a lot smaller than we think, with only a minor fraction of information from bots reaching active social media users.

Enhancing blood sugar control boosts brain health for people with type 2 diabetes

Controlling blood sugar levels improved the ability to clearly think, learn and remember among people with type 2 diabetes who were overweight, a new study shows. But losing weight, especially for people who were obese, and increasing physical activity produced mixed results.

HER2+ breast cancer patients live longer if drugs given before surgery eradicate tumour

Final analysis of results from a randomised clinical trial of lapatinib and trastuzumab given before surgery in patients with early HER2-positive breast cancer has found that women who had no signs of residual disease after treatment (known as a pathological complete response, pCR) survived longer without the cancer returning than patients who did not. This was more likely to happen in patients who received the two anti-cancer drugs together, rather than as single agents.

Researchers reveal which benign breast disease is most likely to develop into cancer

Benign breast diseases (BBD), which are non-cancerous disorders of the breast, such as lumps, are known to increase the chances of subsequent breast cancer. Now a team of Spanish researchers have found that the way BBD is detected as part of a national screening programme is an indication of which are more likely to become cancerous.

Risk of heart disease in breast cancer patients can be predicted from routine scans

Automated analysis of breast cancer patients' routine scans can predict which women have a greater than one in four risk of going on to develop cardiovascular disease, according to research presented at the 12th European Breast Cancer Conference.

Face masks unlikely to cause over-exposure to CO2, even in patients with lung disease

New research findings contradict statements linking wearing face masks to carbon dioxide poisoning by trapping CO2. During the COVID-19 pandemic the wearing of face masks has become a highly political issue with some individuals falsely claiming that wearing face masks may be putting people's health at risk. The study published in the Annals of the American Thoracic Society shows otherwise.
