You are never too old for an STI – more older adults being diagnosed with STIs such as gonorrhea and syphilis

2024-03-27
Infectious disease expert addresses how to manage the rise in sexually transmitted infections in older adults. STIs in Americans aged 55 to 64 years have more than doubled over the past decade; in England the number of over 45s diagnosed with gonorrhoea and syphilis doubled between 2015 and 2019. Availability of sildenafil (Viagra) in late 1990s had an impact on STIs in older men. Sexual health campaigns overlook the needs and experiences of the baby boom generation. Health professionals must be proactive in discussing sexual concerns and making sexual health a routine part of general health care for older adults. **Note: ...

Robot, can you say ‘cheese’?

Robot, can you say ‘cheese’?
2024-03-27
What would you do if you walked up to a robot with a human-like head and it smiled at you first? You’d likely smile back and perhaps feel the two of you were genuinely interacting. But how does a robot know how to do this? Or a better question, how does it know to get you to smile back? While we’re getting accustomed to robots that are adept at verbal communication, thanks in part to advancements in large language models like ChatGPT, their nonverbal communication skills, especially facial expressions, have lagged far behind. Designing a robot that can not only make a wide range ...

Long-period oscillations control the Sun’s differential rotation

2024-03-27
The Sun’s differential rotation pattern has puzzled scientists for decades: while the poles rotate with a period of approximately 34 days, mid-latitudes rotate faster and the equatorial region requires only approximately 24 days for a full rotation. In addition, in past years advances in helioseismology, i.e. probing the solar interior with the help of solar acoustic waves, have established that this rotational profile is nearly constant throughout the entire convection zone. This layer of the Sun stretches ...

A combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis

2024-03-27
BOSTON – Tuberculosis (TB) is often overlooked in developed countries such as the United States, but this bacterial infection remains one of the deadliest diseases globally and results in millions of deaths annually. Deaths can occur even with treatment, sometimes because of drug resistance in TB bacteria and other times due to poor delivery of TB-targeting drugs to patients’ infected lung tissue. To address the latter challenge, a team led by researchers at Massachusetts General Hospital (MGH) in collaboration with scientists at the National Institute of Allergy and ...

Reevaluating an approach to functional brain imaging
2024-03-27
A new way of imaging the brain with magnetic resonance imaging (MRI) does not directly detect neural activity as originally reported, according to scientists at MIT’s McGovern Institute. The method, first described in 2022, generated excitement within the neuroscience community as a potentially transformative approach. But a study from the lab of McGovern associate investigator Alan Jasanoff, reported March 27, 2024, in the journal Science Advances, demonstrates that MRI signals produced by the new method are generated in large part by the imaging process itself, ...

Food matters: Healthy diets increase the economic and physical feasibility of 1.5°C

2024-03-27
“We find that a more sustainable, flexitarian diet increases the feasibility of the Paris Agreement climate goals in different ways,” says Florian Humpenöder, PIK scientist and co-lead author of the study to be published in Science Advances. “The reduction of greenhouse gas emissions related to dietary shifts, especially methane from ruminant animals raised for their meat and milk, would allow us to extend our current global CO2 budget of 500 gigatons by 125 gigatons and still stay within the limits of 1.5°C with a 50 percent chance,” he adds. Putting a price on greenhouse gas (GHG) emissions ...

Land under water – what causes extreme flooding

Land under water – what causes extreme flooding
2024-03-27
There are several factors that play an important role in the development of floods: air temperature, soil moisture, snow depth, and the daily precipitation in the days before a flood. In order to better understand how individual factors contribute to flooding, UFZ researchers examined more than 3,500 river basins worldwide and analysed flood events between 1981 and 2020 for each of them. The result: precipitation was the sole determining factor in only around 25% of the almost 125,000 flood events. Soil moisture was the decisive factor in just over 10% of cases, and ...

Researchers turn back the clock on cancer cells to offer new treatment paradigm

Researchers turn back the clock on cancer cells to offer new treatment paradigm
2024-03-27
St. Jude Children’s Research Hospital scientists reversed an aggressive cancer, reverting malignant cells towards a more normal state. Rhabdoid tumors are an aggressive cancer which is missing a key tumor suppressor protein. Findings showed that with the missing tumor suppressor, deleting or degrading the quality control protein DCAF5 reversed the cancer cell state. These results suggest a new approach to curing cancer — returning cancerous cells to an earlier, more normal state rather than killing cancer cells with toxic therapies — may be possible. The results were published today in Nature.   “Rather than making a toxic event that kills rhabdoid ...
