Tech makes it possible to digitally communicate through human touch

Researchers at Purdue University have developed a technology that enables digital communication through direct touch, allowing for secure payments and information transfer without biometric authentication. This innovation uses an "Electro-Quasistatic range" to confine signals within the body, preventing hacking and interception.

Most countries are violating international law during the COVID-19 pandemic: Legal experts

A new study by global health law scholars reveals that most countries are not fulfilling their international legal obligations during the COVID-19 pandemic. The researchers argue that the provisions of the International Health Regulations (IHR) are often misunderstood and may not be sufficient to guide governments' responses to pandemics.

The impact of Neandertal DNA on human health

Researchers analyzed Neandertal-associated phenotypes in Asian and European populations, finding shared variants increasing risk of autoimmune diseases like dermatitis and rheumatoid arthritis. In contrast, a specific gene variant in Asians had a protective effect against prostate cancer.

Gastric bypass surgery leads to long-term diabetes remission

A new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism found that gastric bypass surgery can lead to long-term diabetes remission in over half of adults with type 2 diabetes. The study suggests that weight loss is not the only factor contributing to improved blood sugar levels.

BIOS-SCOPE funding renewed

The BIOS-SCOPE program will continue its research into the microbial ecology of the Sargasso Sea, leveraging over 30 years of data from BATS and other sources. The program brings together researchers from different backgrounds using systems biology, genomics, and marine chemistry to study organic matter cycling and microbial interactions.

Flightless bird species at risk of extinction

A study of extinct bird species reveals that flightlessness developed in many cases due to human impact, with 29% of extinct species lacking the ability to fly. The researchers found that if humans had not caused some extinctions, there would be over 150 independently developed flightless bird groups.

Genetically engineered T cells could lead to therapies for autoimmune diseases

A novel T cell genetically engineered by University of Arizona Health Sciences researchers targets and attacks pathogenic T cells that cause Type 1 diabetes. The 5MCAR T cells, which mimic the evolutionary design of natural killer T cells, were tested in a non-obese diabetic mouse model with promising results.

What makes certain groups more vulnerable to COVID-19?

Researchers analyzed protein sequences of SARS-CoV2 virus and host cell receptors to find commonalities among animals susceptible to infection. Greater cellular oxidation may predispose the elderly and those with underlying health conditions to more severe infection.

Marine mammals' adaptations to low oxygen offer new perspective on COVID-19

A study by UC Santa Cruz professor Terrie Williams explores how marine mammals' physiological adaptations can help understand the effects of COVID-19. Marine mammals have evolved mechanisms to protect critical organs during low-oxygen conditions, which may inform strategies for humans to mitigate long-term damage from oxygen deprivation.

US state government crisis standards of care guidelines

State crisis standards of care (CSC) guidelines in the US allocate scarce healthcare resources among cancer patients, requiring careful consideration of prioritization methods. The guidelines include provisions for blood products and palliative care, highlighting the need for nuanced decision-making in resource allocation.

Ancient migration was choice, not chance

Researchers used satellite-tracked buoys to simulate ancient ocean migrations. They found that the vast majority failed to reach the Ryukyu Islands due to adverse weather conditions, suggesting intentional navigation. The study provides evidence of Paleolithic people's bold exploration and migration.

Drinking linked to a decline in brain health from cradle to grave

Research highlights three key periods of dynamic brain changes sensitive to alcohol's effects: gestation, later adolescence, and older adulthood. Low or moderate drinking during pregnancy is associated with poorer outcomes in offspring, while binge drinking in adolescence and aging affects brain volume and cognitive functions.

Chemists get peek at novel fluorescence

Rice University scientists have discovered a novel phenomenon in carbon nanotubes, where a delayed secondary fluorescence is emitted when triggered by a multistep process involving dye molecules and dissolved oxygen. The delay, only microseconds long, can be detected with specialized instrumentation.

For nationalistic regimes, similar COVID-19 policies are the sincerest form of flattery

A University of Texas at Arlington study reveals that nationalistic countries emulate each other's COVID-19 policies, favoring national identity over scientific data. The research suggests growing international cooperation among nationalist regimes and leaders, despite geographical distance and varying political systems.

How the vaginal microbiome may affect HIV prevention

A study found that vaginal bacteria associated with bacterial vaginosis can metabolize HIV prevention drugs, reducing their effectiveness. This imbalance can increase the risk of HIV transmission in women. The researchers highlight the need for better treatments and studies on women's health to improve HIV prevention efforts.
