Study finds children distinguish between willingly given and coerced expressions of remorse. Findings suggest that exploring ways to help the child learn to have empathy for the victim, thus ensuring a sincere apology, is more constructive than immediately coercing a reluctant “I’m sorry.”


Babies kicking in the womb are creating a map of their bodies, suggests a new EEG study.


A nationwide study of more than 63,000 cases of cardiac arrest found that ambulances on average took nearly four minutes longer to handle calls from low-income areas than high-income communities.


Hospitals are overburdening doctors with high workloads, resulting in increasing physician burnout and suicide. A new study finds that burned-out physicians are 2x as likely to cause patient safety incidents and deliver sub-optimal care, and 3x as likely to receive low satisfaction ratings.

Study of more than 50,000 people finds 12 regions of DNA that seem to play a role in increasing ADHD risk, with correlations to risk of depression and anorexia. Some of the genes are involved in other neurological conditions, including speech and learning disabilities, depression, and schizophrenia.


A new study has found that burned-out physicians are twice as likely to be involved in patient safety incidents, twice as likely to deliver sub-optimal care to patients owing to low professionalism, and three times more likely to receive low satisfaction ratings from their patients.

"Children from high-income (top 1%) families are ten times as likely to become inventors as those from below-median income families. These gaps persist even among children with similar math test scores in early childhood."


Peacekeeping is extremely effective, far more so than previous studies have shown. If the UN had invested $200 billion in PKOs with strong mandates over the period 2001-2013, major armed conflict would have been reduced by up to two thirds and 150,000 lives would have been saved.


Older people can come to believe their own lies - New EEG research shows that within an hour of telling a falsehood, seniors may think it's the truth. Findings suggest that telling a falsehood scrambles older people’s memory so they have a harder time recalling what really happened.


Scientists have proposed 4 Days of Intensive Therapy Can Reverse OCD for Years. The therapy encourages patients to pay attention to the moments when they feel the urge to start taking control to reduce anxiety or discomfort


Despite an uptick in anti-vaccine legislation proposed by state lawmakers in recent years, pro-vaccine bills were more likely to be enacted into law, according to a new study. “It is reassuring to know that the legislative process is working in favor of public health.“


Patients with moderate to severe depression reported significant improvements in mood when researchers precisely stimulated a brain region called the orbitofrontal cortex (OFC), according to a UC San Francisco research study


Archaeologists discovered a cache of ancient stone blades in northern Tibet from some 30,000 years ago. It's the earliest evidence for people living at high altitude and means humans were living in the harsh conditions of the miles-high Tibetan Plateau much earlier than previously thought.


A new indicator of ancient CO2-levels, using the organic molecule phytane, has been developed providing the most continuous record of CO2-concentrations ever. The data show that present rises in CO2-levels that used to take millions of years, are now happening in a century.

Wound dressings that apply subtle electric pulses reduced healing times in mice to a mere three days compared to nearly two weeks for the normal healing process.


The Amazon is worth $8.2 billion a year if it’s left standing, finds a new study in Nature. In many parts of the rainforest, that economic benefit far outweighs the short-term gain of tearing it down. “The forest should unambiguously be saved when measured in a purely economic sense”.


Earliest evidence for humans on the 'roof of the world' found: Thousands of artifacts on the Tibetan Plateau showcase the resiliency of early humans, and could shed light on how DNA from Denisovans—a mysterious sister species of humans that lived in Siberia—may have helped modern Tibetans thrive.


2.4-million-year-old stone tool artifacts found in Algeria suggest that ancestral hominins inhabited the Mediterranean fringe in Northern Africa much earlier than previously thought.


The US government spent $27 billion to get hospitals and doctors adopt electronic health records. Now that they are nearly ubiquitous, EHR adoption has been found to cut costs and the average hospital visit by 4 hours — but only when hospitals meet the highest use standards.


CDC says life expectancy down as more Americans die younger due to suicide and drug overdose


In a controversial new study, researchers point to ancient cave paintings as proof that people who lived nearly 40,000 years ago had advanced knowledge of astronomy. If true, this theory would dramatically change the timeline of humanity’s understanding of the natural world.


NASA’s next Mars mission will have a helicopter onboard. The Mars 2020 mission, slated to launch in July 2020, is a rover designed to look for signs of past or present life on the Red Planet. NASA has just announced that another explorer called the Mars Helicopter will be hitching a ride.


Scientists have found a 33-million-year-old whale fossil that had neither teeth nor baleen. Based on its relationship to other whales, the findings suggest that whales lost teeth first, and only developed baleen later.

Researchers have created a way to convert plastic bottle waste into ultralight polyethylene terephthalate aerogels for a variety of useful applications, like heat and sound insulation, oil spill cleaning, carbon dioxide absorption, as well as fire safety applications.


New research (N = 9,205) shows that religious people know less about science, possibly because they view science less positively. Surprisingly, parental religious beliefs were related to their children's attitudes about science nearly 20 years later in life.

Extreme heat from climate change a 'medical emergency,' sickening tens of millions worldwide


Scientists demonstrate passive cooling setup (no power needed) which cools 6 degree C below ambient temperatures (potentially up to 20 C below) by using a shade against direct sunlight, and then radiating out diagonally at mid-infrared frequencies which are harder to trap with greenhouse gases


Easy to use 3D bioprinting technique creates lifelike tissues from natural materials - As a proof of concept, scientists used their method to create blood vessel networks capable of keeping a breast cancer tumor alive outside the body. They also created a model of a vascularized human gut.


A prosthetic arm that decodes phantom limb movements - About 75% of amputees exhibit mobility of their phantom limb. Researchers developed a prototype capable of detecting these movements and activating a prosthetic arm. The prosthesis does not require any surgery and patients do not need training.


This new bionic arm requires no surgery or extensive training, using instead a phenomenon called "phantom limb mobility" to control it


Human skin contains sensitive nerve cells that allow tactile interactions with the environment. To help robots and prosthetic devices attain these abilities, researchers created an ultrathin, stretchable electronic skin which could be used for a variety of human-machine interactions.


Using a mathematical model, researchers show how a society can become polarized, even if everybody is acting in good faith to pursue the truth.


New accelerator-based technology aims to reduce the side effects of cancer radiation therapy by shrinking its duration from minutes to under a second. Built into future compact medical devices, this technology could also help make radiation therapy more accessible around the world


Scientists have grown “mini placentas,” a development that could transform research into the underlying causes of miscarriage, stillbirth, and other pregnancy disorders. The mini placentas are so much like the real thing they can fool over-the-counter pregnancy tests.
