Can taking statins after a bleeding stroke lower risk of another stroke?

People who have had a stroke called an intracerebral hemorrhage who take cholesterol-lowering drugs called statins may have a lower risk of having another stroke, especially ischemic stroke, compared to people who also had an intracerebral hemorrhage but were not taking statins.

Rare 14-ft smalltooth sand tiger shark washes up on Irish coast

Scientists believe a huge 14ft smalltooth sand tiger shark, which washed up at Kilmore Quay, Co. Wexford, earlier this year, represents the first of its species to have been found in Ireland's waters. Two other individuals of the same species also washed up on the UK coastline, suggesting this species' geographic range has shifted. The scientists believe these rare finds may offer a window into the future, with more and more species traditionally confined to more tropical waters expected to visit Irish and British waters.

Bat study reveals how the brain is wired for collective behavior

Researchers used wireless neural recording and imaging devices to 'listen in' on the hippocampal brain activity of groups of Egyptian fruit bats as they flew freely within a large flight room. The researchers were surprised to find that, in this social setting, the bat's 'place' neurons encoded not only the animal's location, but also information about the presence or absence of other bats, and even the identity of bats in their path.

How brucellosis -- which can jump from animals to humans -- impacts the brain

Brucellosis is a disease, caused by the members of bacterial Brucella family, that mainly infects cattle, goats and sheep, leading to pregnancy loss, which has caused billions of dollars in economic losses for livestock producers worldwide. The disease can also jump from animals to humans, mainly through consumption of unpasteurized dairy products or inhaling the spores from the tissues of infected animals. While the disease can cause arthritis, inflammation of the heart and flu-like symptoms in humans, the bacteria can also enter the brain and cause neurobrucellosis, which can lead to long-term neurological complications, headaches, nausea, disorientation, swelling of the brain and sometimes death. Now, a new study has highlighted the protective power of both innate lymphoid cells and specific signaling proteins, known as interferons, in reducing the harmful neurological effects of Brucella.

The research focuses on more recent technologies that produce images at a much closer scale, allowing for subcellular resolution (or multiple measurements per cell). While these techniques solve the resolution issue, they present new challenges because the resulting images are so close-up that rather than capturing 15 to 50 cells per image, they capture only a few genes. This reversal of the previous problem creates difficulties in identifying the individual components and determining how to group these measurements to learn about specific cells. It also obscures the big picture.

Remission from HIV-1 infection: Discovery of broadly neutralizing antibodies that contribute to virus control

Some HIV-1 carriers who have received an early antiretroviral treatment during several years are able to control the virus for a long term after treatment interruption. However, the mechanisms enabling this post-treatment control have not been fully elucidated. Scientists have now investigated and revealed how neutralizing antibodies, including those described as broadly neutralizing, contribute to virus control. A clinical trial involving the use of broadly neutralizing antibodies should begin in France before the end of 2023.

The war-damaged urban environment in Kharkiv is fatal for bats

Russia's war in the Ukraine has severe consequences not only for humans, it also has detrimental effects on populations of urban and semi-urban wildlife in the attacked cities and regions. Scientists recently examined the effects of war-related damages to buildings on urban populations of one important and widespread bat species, the Common Noctule (Nyctalus noctula), in the city of Kharkiv in north-eastern Ukraine. They showed that many buildings used by bats as roosts have been destroyed and approximately 7,000 bats were killed. In addition, partially destroyed buildings have become a death trap for bats, resulting in several thousand more victims.

Prenatal diagnosis matters: Linked to earlier surgery for congenital heart disease

A study has shown that prenatal diagnosis, or diagnosis before a baby is born, is associated with earlier surgery for babies with congenital heart defects, the most common birth defects affecting nearly 1% of all live births. The association was demonstrated for critical defects (when heart surgery is required before the infant leaves the hospital) and certain types of noncritical defects, which constitute about 75% of all congenital heart defects.

Researchers propose a data-driven strategy to stratify risk of progression from mild cognitive impairment to Alzheimer's disease

The projected cost of caring for millions of individuals who have Alzheimer's disease (AD) worldwide will exceed a $1 trillion in a few years. In addition to the enormous health burden, patients and their caregivers experience financial, physical and psychological strain. A theory regarding repeated drug failure in AD is that patients undergoing experimental therapies are selected too late in the disease process. Therefore, it is important to identify patients at a high risk of progression to AD in early stages of the disease. To help identify persons who could benefit from early interventions, researchers from Boston University have developed a deep learning framework that can stratify individuals with mild cognitive impairment (MCI) based on their risk of advancing to AD.

Continuous-flow manufacturing of essential antibiotic cefazolin: Flexible production while reducing costs

The antibiotic cefazolin is an essential drug according to the World Health Organization (WHO). It is usually produced via batch manufacturing, but this multistep process is time-consuming, wasteful and requires very specialized facilities. Now, researchers have manufactured cefazolin using the continuous-flow method. This method is cheaper, quicker, less wasteful and more flexible in terms of how much drug can be produced when it's needed. Improving access to cefazolin is vital for global health and particularly relevant for countries such as Japan, which experienced a shortage in 2019.

Potential new tool for early identification of dementia risk

By analyzing data from nearly 13,000 subjects who participated in a long-term aging study, researchers found that an interviewer's rating of a cognitively healthy person's memory successfully predicted the likelihood of developing dementia over a 15-year period.

Novel molecules fight viruses by bursting their bubble-like membranes

Antiviral therapies are notoriously difficult to develop, as viruses can quickly mutate to become resistant to drugs. But what if a new generation of antivirals ignores the fast-mutating proteins on the surface of viruses and instead disrupts their protective layers?

Score, then rank: Researchers propose an integrated approach to grant review assessments

The public funding of science is responsible for many of the biomedical and other scientific breakthroughs on which our lives depend. However, the process through which funding decisions are made, the peer review of grant proposals, has been historically understudied, and current approaches can lead to undesirable outcomes.

Sweet smell of success: Simple fragrance method produces major memory boost

When a fragrance wafted through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially deterring dementia.
