Camargue flamingos starved in freezing conditions in 1985 and 2012 mass mortalities

A 1985 mass mortality and a 2012 severe cold snap led to the deaths of nearly one-third of Camargue flamingo population. The study suggests that freezing temperatures increased the birds' energy demands, tipping them into starvation. The researchers found that the 2012 event had a lower death toll due to milder temperatures.

Brain surgery through the cheek

Researchers at Vanderbilt University have developed a robotic device that can treat severe epilepsy with a minimally invasive procedure. The system uses a shape-memory alloy needle steered by a robotic platform to destroy the area where seizures originate, avoiding drilling through the skull.

Slow and steady does not win the weight loss race

A new study published in The Lancet Diabetes & Endocrinology found that substantial weight loss is more likely achieved through rapid weight loss programmes. Researchers compared two groups: one following a 12-week rapid weight loss programme with an average weekly weight loss of 1.5kg, and the other on a 36-week gradual weight loss pr...

Personalized cellular therapy achieves complete remission in 90 percent of acute lymphoblastic leukemia patients studied

A personalized cellular therapy called CTL019 achieved complete remission in 27 of 30 patients with relapsed or refractory acute lymphoblastic leukemia, with 78% remaining alive six months post-treatment. The treatment involves infusing engineered immune cells that target cancer cells.

Three hours of life per euro

A study found that each additional euro spent on pensions and public health insurance in Eastern Germany increased life expectancy by 3 hours. Public health care had a greater impact, contributing 2.5 times more to life expectancy than pension payments.

Pattern recognition receptors may be potent new drug targets for immune-mediated diseases

The article highlights the role of pattern recognition receptors in regulating immune responses and their potential as novel targets for developing potent new therapies. The JAK/STAT signaling network also plays a crucial role in disease pathogenesis, and targeting these networks may lead to improved treatments for various diseases.

Risking your life without a second thought

An analysis of statements from 51 recognized civilian heroes found that most describe their acts as intuitive, rather than deliberate. This suggests that high-stakes extreme altruism may be largely driven by automatic, instinctual processes.

Rivers flow differently over gravel beds, study finds

Researchers found dramatic differences in flow velocity patterns and forces on river beds between gravel and sandy models, disproving a popular theory. The study's new parameters improve predictive models for nutrient and pollutant transport and provide insight into organism behavior in the narrow zone where rivers meet their beds.

Light pollution contributing to fledgling 'fallout'

A 15-year study found thousands of birds are attracted to artificial lights during their first flights, leading to high mortality rates. Turning street lights off decreased the number of grounded fledglings, suggesting a link between light pollution and bird deaths.

Extinct giant kangaroos may have been hop-less

New research suggests that extinct giant kangaroos likely walked instead of hopped, with stiff backs and strong joints supporting their body posture. The study analyzed anatomical differences in limb bones compared to other kangaroo species.

Ebola highlights disparity of disease burden in developed vs. developing countries

The study found that measles death rates were 197 times greater in developing countries than in developed countries, while syphilis death rates were 33-45 times higher. Ebola mortality rates were also significantly higher in developing countries, with 4,447 deaths compared to just two in developed nations.

Bullies in the workplace

A study by Iowa State University researchers found that workplace bullying victims often feel silenced due to fear of being disbelieved. Supportive co-workers and managers can help create a culture where victims feel heard and believed.

Change your walking style, change your mood

Researchers showed subjects a list of positive and negative words, then asked them to walk on a treadmill while measuring their gait and posture. The study found that those who walked in a depressed style recalled more negative words from the earlier list, suggesting a link between walking style and mood.

Blinded by science

A study by Cornell Food & Brand Lab found that trivial elements like graphs and formulas can lead consumers to believe products are more effective. The researchers concluded that presenting consumers with 'scientific looking' information increases product confidence because individuals trust the appearance of scientific validity.

The Lancet Diabetes & Endocrinology: Gradual weight loss no better than rapid weight loss for long-term weight control

A new study published in The Lancet Diabetes & Endocrinology found that gradual weight loss is not more effective than rapid weight loss for achieving long-term weight control. In the trial, participants who lost weight quickly were more likely to achieve target weight loss and had lower drop-out rates.

Tuning light to kill deep cancer tumors

A novel strategy combining nanoparticle technology with FDA-approved photodynamic therapy has been developed to effectively kill deep-set cancer cells in vivo. The treatment uses low-power, deep-tissue-penetrating light to activate the cancer-killing drug, showing improved destruction of tumors with minimal damage to surrounding tissue.

Study identifies risk factors for sexual assault, including age and alcohol consumption

A Danish study found that women aged 15-24 years old were more likely to be sexually assaulted, while those who consumed over 5 units of alcohol were at risk of being attacked by a stranger. The study highlights the need for awareness and education among healthcare professionals, police, and the general public to prevent sexual assault.
