Disordered eating is not only a disease of affluent girls

Science Daily - 31/01/2023
Predominant stereotypes about eating disorders suggest that it is a condition mainly associated with girls from wealthy backgrounds. However, a new study found that boys living in disadvantaged circumstances are at an increased risk for disordered eating, particularly if they have underlying genetic risk factors.

Artificial intelligence aids discovery of super tight-binding antibodies

Scientists developed an artificial intelligence tool that could accelerate the development of new high affinity antibody drugs.

Three or more concussions linked with worse brain function in later life

Science Daily - 31/01/2023
Experiencing three or more concussions is linked with worsened brain function in later life, according to major new research. The study -- the largest of its kind -- also found having just one moderate-to-severe concussion, or traumatic brain injury (TBI), can have a long-term impact on brain function, including memory.

Short-term bang of fireworks has long-term impact on wildlife

Science Daily - 31/01/2023
Popular fireworks should be replaced with cleaner drone and laser light shows to avoid the 'highly damaging' impact on wildlife, domestic pets and the broader environment, new research has found.

Monitoring an 'anti-greenhouse' gas: Dimethyl sulfide in Arctic air

Science Daily - 31/01/2023
Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can significantly affect weather and climate.

How to reduce the temptation to cheat: Empathy

Science Daily - 31/01/2023
Adopting a partner's perspective increases commitment and desire for the partner, while simultaneously decreasing sexual and romantic interest in alternative mates, according to a new study by a team of psychologists. The findings suggest that perspective taking discourages people from engaging in behaviors that may hurt their partners and damage their relationship.

This groundbreaking biomaterial heals tissues from the inside out

Science Daily - 31/01/2023
A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

New method to control electron spin paves the way for efficient quantum computers

Science Daily - 31/01/2023
Researchers have developed a new method for manipulating information in quantum systems by controlling the spin of electrons in silicon quantum dots. The results provide a promising new mechanism for control of qubits, which could pave the way for the development of a practical, silicon-based quantum computer.

Marburg vaccine shows promising results in first-in-human study

Science Daily - 30/01/2023
A new article shows that an experimental vaccine against Marburg virus (MARV) was safe and induced an immune response in a small, first-in-human clinical trial. The vaccine could someday be an important tool to respond to Marburg virus outbreaks.

Sports-related sudden cardiac arrest is rare in older adults

Science Daily - 30/01/2023
The annual incidence of sports-related sudden cardiac arrest in older adults is rare: 2 to 3 cases per 100,000 people.

Machine learning identifies drugs that could potentially help smokers quit

Science Daily - 30/01/2023
Medications like dextromethorphan, used to treat coughs caused by cold and flu, could potentially be repurposed to help people quit smoking cigarettes, according to a new study. Researchers developed a novel machine learning method, where computer programs analyze data sets for patterns and trends, to identify the drugs and said that some of them are already being tested in clinical trials.

New ancient 'marine crocodile' discovered on UK's Jurassic Coast -- and it's one of the oldest specimens of its type ever found

Science Daily - 30/01/2023
A new study has uncovered a new thalattosuchian -- an ancient 'sister' of modern-day crocodiles' ancestors.

Will machine learning help us find extraterrestrial life?

Science Daily - 30/01/2023
Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of interest.

Researchers make recommendations for diversifying syllabi in higher education

Science Daily - 30/01/2023
Researchers set up a structure that helps them systematically go through different types of resources and figure out if they meet the aims of diversifying syllabi.

Under pressure: Breakthrough new material solves problem of wearable sensors

Science Daily - 30/01/2023
Researchers have synthesized a new material that solves one of the most difficult problems in the quest to create wearable, unobtrusive sensitive sensors: the problem of pressure.

Tweezers untangle chemotherapeutic's impact on DNA

Science Daily - 30/01/2023
New research is providing a fresh view into the ways a common chemotherapy agent, etoposide, stalls and poisons the essential enzymes that allow cancer cells to flourish.

New insights on why improvements to Chesapeake Bay remain a challenge

Science Daily - 30/01/2023
A new look at the history of water quality in the Chesapeake Bay sheds light on how the estuary has responded to nutrient reduction efforts and why improvements have remained a major challenge. Environmental science researchers looked at the Bay's historic response to efforts to reduce nutrients to minimize dead zones -- areas with too little oxygen to support marine life -- and found there is a pollution threshold after which it takes twice the effort to make a change.

Powering wearable technology with MXene textile supercapacitor 'patch'

Science Daily - 30/01/2023
Researchers are one step closer to making wearable textile technology a reality. Materials scientists have reported a new design of a flexible wearable supercapacitor patch. It uses MXene to create a textile-based supercapacitor that can charge in minutes and power an Arduino microcontroller temperature sensor and radio communication of data for almost two hours.
