Smartphone sensor data has potential to detect cannabis intoxication

A smartphone sensor, much like what is used in GPS systems, might be a way to determine whether or not someone is intoxicated after consuming marijuana, according to a new study.

Researchers develop new method for detecting superfluid motion

Researchers are part of a new study that could help unlock the potential of superfluids -- essentially frictionless special substances capable of unstopped motion once initiated.

When it comes to communication skills, maybe we’re born with it?

A neuroscientist and speech pathologist, led a study that uncovered how neural networks in infants influence their language learning skills in early childhood.

3D nano-inks push industry boundaries

A new, 3D-printable polymer nanocomposite ink developed by engineers has incredible properties like conducting electricity and high tensile strength -- and many applications in aerospace, medicine and electronics.

The origin and legacy of the Etruscans

Researchers present comprehensive ancient DNA data retrieved from peoples culturally affiliated with the iconic Etruscans, settling a long-lasting debate on the origins of this highly skilled and enigmatic culture.

In a gene tied to growth, scientists see glimmers of human history

A new study delves into the evolution and function of the human growth hormone receptor gene, and asks what forces in humanity's past may have driven changes to this vital piece of DNA.

Guiding microbes along their path

The direction of movement of a microbe directly depends on the curvature of its environment, according to new findings. The researchers investigated the navigation of a model microbe, a small self-propelling microalga, in confined compartments with different shapes. They also developed theoretical models to predict the probability flux of that microswimmer which was confirmed by experiments. With this model available, it is now possible to pre-define the average trajectory of such microbes by manipulating the curvature of the compartments which directly affects their movement.

New technique speeds measurement of ultrafast pulses

Researchers have developed a time-domain single-pixel imaging technique to speed the measurement of ultrafast pulses in infrared and far infrared wavelengths.

In the race to reduce car emissions, don't forget longevity

The debate on green vehicles often focuses on fuel efficiency and alternative fuels, with the transition to fuel alternatives commonly being considered better for the environment the faster it is. A new study shows that keeping and using existing fuel-efficient cars a little longer can actually reduce CO? emissions even with gasoline cars. Thus, a gradual transition and policies that encourage a change in consumption patterns are also key for reducing overall emissions.

Insights from our genome and epigenome will help prevent, diagnose and treat cancer

In 2020, an estimated 10 million people lost their lives to cancer. This devastating disease is underpinned by changes to our DNA -- the instruction manual for all our cells.

Gamma rays and neutrinos from mellow supermassive black holes

The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles' origins remain unexplained.

New cause of inherited heart condition discovered

The discovery provides a new causal explanation for 1-2% of adults with the condition.

Tiny lasers acting together as one: Topological vertical cavity laser arrays

An international research team uses topological platform to demonstrate coherent array of vertical lasers.

Observations confirm that aerosols formed from plant emitted compounds can make clouds brighter

An observational study confirms a prevailing theory that volatile organic compounds emitted by vegetation form atmospheric aerosols which make clouds more reflective.

Radiation therapy reprograms heart muscle cells to younger state

New research suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure.

Machine learning uncovers 'genes of importance' in agriculture and medicine

Machine learning can pinpoint 'genes of importance' that help crops to grow with less fertilizer, according to a new study. It can also predict additional traits in plants and disease outcomes in animals, illustrating its applications beyond agriculture.

Lab grown tumor models could improve treatment for pancreatic cancer

An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments.

Systems approach helps assess public health impacts of changing climate, environmental policies

Scientists offer an alternative way to understand and minimize health impacts from human-caused changes to the climate and environment.

Novel small molecule potently attenuates neuroinflammation in brain and glial cells

In a preclinical study show that their small molecule drug, SRI-42127, can potently attenuate the triggers of neuroinflammation. These experiments in glial cell cultures and mice now open the door to testing SRI-42127 in models of acute and chronic neurological injury.

If endangered primates disappear, so will their parasites. That's actually a problem

People are more aware of the plight of endangered gorillas than of gorillas' gut worms, and are understandably more enamored with mouse lemurs than their mites. Half of the world's roughly 500 primate species are at risk of extinction due to human activities such as hunting, trapping and deforestation. But the demise of the world's threatened primates could also trigger even more extinctions for the parasites that lurk within them, finds a new study.
