Killer whales are so smart they can learn to speak "dolphin" Killer whales are smart, we already know that; they’re also really scary.
But a new study has shown that they are actually scary smart – up to the point where they can learn the language of another species. Killer Smart Killer whales are actually a species of dolphins found in all oceans, from the frigid Arctic and Antarctic regions to tropical seas. Mirror image processing in three marine mammal species: killer whales (Orcinus orca), false killer whales (Pseudorca crassidens) and California sea l... ¿Onda o partícula? Cockroaches Accumulate Light to See in the Dark. Cockroaches could inspire superheroes if they weren't so repulsive.
Some species can hold their breath for as long as 40 minutes. Others can survive blasts of strong radiation, subsist on paper and dried glue, or live for weeks without a head. Recently researchers discovered another superpower: the nocturnal creatures can see in near–pitch black by pooling light signals over time, like time-lapse photography. Physicists at the University of Oulu in Finland—where it is too cold for roaches to live outside of the laboratory—put about 30 American cockroaches through virtual-reality experiments to test their night vision. No, they did not make them wear tiny goggles. The scientists also harmlessly inserted a recording microelectrode into one of the roaches' nearly 360-degree compound eyes to record the electric blips triggered in the photoreceptor cells by photons, or particles of light. Usually such conditions are too dim for vision. Psychoactive Plant May Hold Key to Reversing Diabetes.
New research published in Nature Medicine may have unlocked a new line of treatment for diabetes.
The researchers honed in on the main culprits in diabetes: beta cells. These cells concentrate in the pancreas in little clusters called islets, and they produce the insulin necessary to keep the body’s blood sugar levels stable. “In children and adults with type 1 diabetes, they’ve lost 99 percent of their beta cells, so they cannot make enough insulin. That’s the cause of their diabetes,” said Andrew Stewart, director of the Diabetes, Obesity and Metabolism Institute at the Icahn School of Medicine at Mount Sinai, New York City and senior author of the study, in an interview with Healthline.

Stopping HIV with an artificial protein. For 30 years, researchers have struggled to determine which immune responses best foil HIV, information that has guided the design of AIDS vaccines and other prevention approaches.
Now, a research team has shown that a lab-made molecule that mimics an antibody from our immune system may have more protective power than anything the body produces, keeping four monkeys free of HIV infection despite injection of large doses of the virus. Intensive hunts are under way for natural HIV antibodies that can stop—or “neutralize”—the many variants of the constantly mutating AIDS virus. Researchers have recently found several dozen broadly neutralizing antibodies (bNAbs) that are highly potent and work at low doses. GNN - Genetics and Genomics Timeline.
Theodor Boveri (1862-1915) establishes the individuality and continuity of chromosomes Amidst much interest in cell structure and development, in 1887 Theodor Boveri began investigating chromosomes.
No Big Bang? Quantum equation predicts universe has no beginning. (Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity.
The model may also account for dark matter and dark energy, resolving multiple problems at once. The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a "Big Bang" did the universe officially begin.

Mind over Matter: Can You Think Your Way to Strength? Researchers explore the power of mental visualization in maintaining real-life muscle Bethesda, Md. (December 31, 2014)—Anyone who has worn a cast knows that rebuilding muscle strength once the cast is removed can be difficult. Now researchers at the Ohio Musculoskeletal and Neurological Institute (OMNI) at Ohio University have found that the mind is critical in maintaining muscle strength following a prolonged period of immobilization and that mental imagery may be key in reducing the associated muscle loss. Strength is controlled by a number of factors—the most studied by far is skeletal muscle.
Of the group with wrist-hand immobilization, half (14) were asked to regularly perform an imagery exercise, imagining they were intensely contracting their wrist for five seconds and then resting for five seconds. Physiology is the study of how molecules, cells, tissues and organs function in health and disease. Immanence and Deterritorialization: The Philosophy of Gilles Deleuze and Félix Guattari. 1. Introduction. Imagination, reality flow in opposite directions in the brain.
As real as that daydream may seem, its path through your brain runs opposite reality. Aiming to discern discrete neural circuits, researchers at the University of Wisconsin-Madison have tracked electrical activity in the brains of people who alternately imagined scenes or watched videos. "A really important problem in brain research is understanding how different parts of the brain are functionally connected.
WIFI-studies. Hawking contra Philosophy. Articles Christopher Norris presents a case for the defence. Stephen Hawking recently fluttered the academic dovecotes by writing in his new book The Grand Design – and repeating to an eager company of interviewers and journalists – that philosophy as practised nowadays is a waste of time and philosophers a waste of space. More precisely, he wrote that philosophy is ‘dead’ since it hasn’t kept up with the latest developments in science, especially theoretical physics.

Chemical engineering applies the natural sciences and life sciences together with mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy.
It also deals with the engineering of chemicals, energy and the processes that create and/or convert them. Modern chemical engineering is concerned with processes that convert raw materials or chemicals into more useful or valuable forms. They are also concerned with pioneering valuable materials and related techniques which are often essential to related fields such as nanotechnology, fuel cells and bioengineering. The varying aspects of chemical engineering play a vital role and the feature explains the chemical engineering aspects with the help of animations. Watch 80,000 Neurons Fire in the Brain of a Fish.
