New research carried out by City, University of London data scientist, Dr Andrea Baronchelli, and colleagues into the dark web marketplace (DWM) trade in products related to COVID-19, has revealed the need for the continuous monitoring of dark web marketplaces (DWMs) especially in light of the current shortage and availability of coronavirus vaccines.

A new study further highlighting a potential physiological cause of clinical depression could guide future treatment options for this serious mental health disorder. Published in Frontiers in Psychiatry, researchers show differences between the cellular composition of the brain in depressed adults who died by suicide and non-psychiatric individuals who died suddenly by other means.

ANN ARBOR, Mich. - The suicide rate among American adolescents has rose drastically over the last decade, but many at-risk youths aren't receiving the mental health services they need.

In fact, one of the greatest challenges is identifying the young people who need the most help.

Mothers are at increased risk of mental health problems as they struggle to balance the demands of childcare and remote working in COVID-19 lockdowns, according to new research from an international team of researchers.

The findings, published in the journal Psychological Medicine, were drawn from a comprehensive, online survey of mothers in China, Italy and the Netherlands.

Changes to their working lives, family strife and loss of social networks emerged as common factors affecting the mental health of mothers in all three countries.

The COVID-19 pandemic has had a profound effect on higher education -- shifting classes online, canceling events, and putting financial strain on institutions.

In the wake of repeated school shootings across the United States, today's youth have been called the mass shooting generation. A new study examined public support for arming school employees. The study found consensus for arming school resource officers, but division over whether to arm teachers and nonteaching staff. The research has clear implications for policy, including the possibility that support for arming school staff may diminish over time as young people (who are less supportive) make up a larger share of voters.

In the first longitudinal study to follow Georgia pre-K students through middle school, Stacey Neuharth-Pritchett, associate dean for academic programs and professor in UGA's Mary Frances Early College of Education, found that participating in pre-K programs positively predicted mathematical achievement in students through seventh grade.

During the lockdown in the first wave of the COVID-19 pandemic in Spain, pregnant women had higher symptoms of depression and anxiety. The finding comes from a study published in Acta Obstetricia et Gynecologica Scandinavica, which also revealed that women with higher body mass index and lower social support were most affected.

A total of 204 women accepted to participate in the study, which involved completing questionnaires related to depression, anxiety, and social support.

Previous studies have linked sleep deprivation and frailty with depression. A new study published in the Journal of the American Geriatrics Society that examined their combined effect suggests that short sleep intensifies the impacts of frailty on depressive symptoms.

A brain-related visual impairment, which until recently was thought to be rare, may affect one in every 30 children according to new research investigating the prevalence of Cerebral Visual Impairment [CVI]. The University of Bristol-led findings published today [3 February] in Developmental Medicine and Child Neurology, aim to raise awareness of CVI among parents and teachers to help them identify signs of the condition earlier.

A study of factors associated with Post-Traumatic Stress Disorder (PTSD) has led to a number of novel findings linking nutrition to experiences of PTSD. Notable among them is the discovery that Canadians, between the ages of 45 and 85, were less likely to exhibit PTSD if they consumed an average of two to three fiber sources daily.

PROVIDENCE, R.I. [Brown University] -- Studies have shown that nearly half of all medical students in the U.S. report symptoms of burnout, a long-term reaction to stress characterized by emotional exhaustion, cynicism and feelings of decreased personal accomplishment. Beyond the personal toll, the implications for aspiring and practicing physicians can be severe, from reduced quality of care to increased risk of patient safety incidents.

Period poverty, a lack of access to menstrual hygiene products, and other unmet menstrual health needs can have far-reaching consequences for women and girls in the United States and globally.

Greenhouse gas (GHG) emissions from agriculture, forestry and other land uses (AFOLU sector) cover the 24% of global emissions, representing the second hot spot in the contribution to climate change after the energy sector.

The main drivers are CO2 emissions from deforestation, methane (CH4) emissions produced by ruminant livestock and by anaerobic fermentation of organic matter, mainly from rice crops, and nitrous oxide (N2O) emissions from fertilizer use. Thus, the land sector plays a crucial role in the contribution to climate change.

Chronic stress could be the prevailing condition of our time. In the short term, our jaws or stomachs may clench; in the long term, stress can lead to metabolic disease and speed up diseases of aging, as well as leading to more serious psychological disorders. The physical manifestations of stress originate in the brain, and they move along a so-called "stress axis" that ends in the adrenal glands. These glands then produce the hormone cortisol.
