Scientists say there’s a 50/50 chance that our Milky Way galaxy will collide with the Andromeda galaxy. Would you take those odds?
Researchers are developing an innovative device designed to deliver chemotherapy directly to the surgical site, aiming to reduce the risk of pancreatic cancer recurrence.
Approved a new initial treatment for advanced non-small-cell lung cancer after clinical trials showed patients lived longer without disease progression, compared to the standard treatment currently…
Scientists have created the world’s fastest microscope, which they hope will answer fundamental questions about how electrons behave.
Designed to mimic human decision-making and physical interaction, the Astribot S1 robot can handle tasks that would traditionally require human dexterity and judgment.
Launched by Stardust Intelligence, a Chinese company, the robot has a human-like upper body structure mounted on a wheeled base.
During its first technical demonstration, the robot was seen folding clothes, sorting items, flipping pans while cooking, vacuuming, and cup stacking, attracting widespread attention in the industry.
Presented in a complete form in a new video, the robot is seen accurately serving tea in a cup. If you are feeling sad and want to listen to any music, the innovative machine can play musical instruments as well.
The search for extraterrestrial life has profound physical, mental and spiritual implications, says Nathalie Cabrol in The Secret Life of the Universe —and it belongs to everyone.

A new study, funded by the National Institute of Mental Health and the National Institute of Neurological Disorders and Stroke, describes a promising way to carry genetic material into the brain to reach cellular targets.
The city is considering whether to spend federal funds to offer personalized transcranial magnetic stimulation, or PrTMS, to public safety personnel who may feel groggy from poor sleep or want to improve interactions with the public.
Dr. Kevin Murphy explained the drug-free, noninvasive therapy at workshops Monday in Turlock. Therapy performed in a clinic directs magnetic pulses to stimulate electrical activity in neurons in the brain to regulate moods and restore mental well-being. The treatment is tailored for each individual based on an EEG and mapping of brain activity.
Murphy said the benefits for first responders will be fewer injuries and complaints, better sleep and employee satisfaction. The doctor said improved sleep is a common denominator for people who come into the clinic struggling with different issues.
“the Cauchy stress tensor completely defines the state of stress at a point inside a material in the deformed state”
The Cauchy Stress Tensor.
Imagine you’re holding a rubber band in your hands and stretching it.
The SI base units of both stress tensor and traction vector are newton per square metre (N/m2) or pascal (Pa), corresponding to the stress scalar. The unit vector is dimensionless.
The Cauchy stress tensor obeys the tensor transformation law under a change in the system of coordinates. A graphical representation of this transformation law is the Mohr’s circle for stress.
The Cauchy stress tensor is used for stress analysis of material bodies experiencing small deformations: it is a central concept in the linear theory of elasticity. For large deformations, also called finite deformations, other measures of stress are required, such as the Piola–Kirchhoff stress tensor, the Biot stress tensor, and the Kirchhoff stress tensor.
