Longitudinal study of SARS-CoV-2 antibodies following vaccination

A longitudinal study of IgG antibody levels in vaccinated healthcare workers was recently uploaded to the preprint server medRxiv*, suggesting that IgG levels could be a reliable indicator of successful vaccination.

Testing unavailability may influence public behaviors and facilitate SARS-CoV-2 transmission

A team of scientists from the University of California, Los Angeles, USA, recently conducted a survey investigating the association between availability of testing facilities and COVID-19-related behavioral aspects. Their findings reveal that testing unavailability independently influences certain COVID-19-related behaviors that may increase the risk of SARS-CoV-2 transmission.

Occupation not a reason for high COVID-19 rates among immigrants in Norway, finds study

A new study has found that the disproportionate rate of COVID-19 among immigrant groups in Norway may not be a result of occupational risks.

New mathematical model identifies role of super-spreaders in SARS-CoV-2 variant emergence

Researchers have developed a new mathematical model which helps characterize factors responsible for the emergence of new SARS-CoV-2 variants and their predominance.

AI study on aggressive form of cancer could improve patient outcomes

International genomics research led by the University of Leicester has used artificial intelligence (AI) to study an aggressive form of cancer, which could improve patient outcomes.

COVID-19 pandemic lockdown measures have caused body weight increases in U.S., finds study

Researchers from the University of California, San Francisco, studied the body weight changes of a longitudinal cohort during the initial SIP (shelter-in-place) orders to better understand the possible downstream health implications of a prolonged SIP. They found a significant increase in body weight over the post-SIP period at a rate of roughly a pound and a half weight gain per month following SIP.

COVID-19 long haulers report persistent neurological symptoms

Researchers at Northwestern University, USA, analyzed "long hauler" patients whose symptoms lasted at least six weeks. They found persistent neurological symptoms, including brain fog and headache.

Can COVID-19 cause hearing loss, vertigo, and tinnitus?

Researchers at the University of Manchester, UK, aimed to systematically review the literature to provide evidence on SARS-CoV-2 and audio-vestibular symptoms. They found that COVID-19 has been tied to hearing loss, vertigo, and tinnitus.

Study measures language-skill improvement by tracking brain activity

A study with first-time learners of Japanese has measured how brain activity changes after just a few months of studying a new language. The results show that acquiring a new language initially boosts brain activity, which then reduces as language skills improve.

Study: Wisdom and loneliness can influence the gut microbial diversity

It may take guts — or more precisely, a diverse gut microbiome — to achieve wisdom and fend off loneliness. Or perhaps it’s the other way around, report UC San Diego researchers.

Size is the only difference between male and female brains, shows study

How different are men and women's brains? The question has been explored for decades, but a new study led by Rosalind Franklin University neuroscientist Lise Eliot is the first to coalesce this wide-ranging research into a single mega-synthesis. And the answer is: hardly at all.

DAPK3 slows tumor growth by activating fierce-sounding STING pathway

The glow of a panther's eyes in the darkness. The zig-zagging of a shark's dorsal fin above the water. Humans are always scanning the world for threats.

Biologists compare pelvic sex differences in humans with chimpanzees

Fossil remains of the human pelvis are rare because the pelvic bones do not preserve very well. Therefore, it has remained unclear when human sex differences in the pelvis evolved: jointly with upright walking, or later, together with the large human brains.

Scientists identify new genetic clues to treat “silent’ stroke

Scientists have identified new genetic clues in people who've had small and often apparently 'silent' strokes that are difficult to treat and a major cause of vascular dementia, according to research funded by the British Heart Foundation (BHF) and published in The Lancet Neurology.

Newly identified pathway controls dangerous overreactions in the body's immune system

Scientists at Sinai Health say they have discovered a new pathway that controls dangerous overreactions in a body's immune system, including deadly forms of hyper-inflammation.

New study may shed light on inflammatory bowel disease

Researchers have found an unexpected synergy between a T-cell stimulatory protein -- the ICOS ligand -- and interleukin-10, an immunoregulatory cytokine, to prevent inflammatory bowel disease in mice.

Researchers use new process to improve deep brain stimulation

Despite having remarkable utility in treating movement disorders such as Parkinson's disease, deep brain stimulation (DBS) has confounded researchers, with a general lack of understanding of why it works at some frequencies and does not at others.

DNMT3a plays a key role in regulating HSC responses to infections

Humans are born with tens of thousands of hematopoietic stem cells (HSCs) that collectively ensure lifelong production of blood and immune cells that protect us from infections.

Taking fish oil provides health benefits only if you have the right genetic makeup, shows study

Fish oil supplements are a billion-dollar industry built on a foundation of purported, but not proven, health benefits. Now, new research from a team led by a University of Georgia scientist indicates that taking fish oil only provides health benefits if you have the right genetic makeup.

Study reveals colorectal cancer risk does not rise after bariatric surgery

Colorectal cancer risk does not rise after bariatric surgery, a study from the University of Gothenburg shows. This finding is important for patients with obesity, and their healthcare professionals, when deciding upon such an operation.
