Mystery of the "Big Bird" Neutrino --IceCube Observatory Detects One of the Most Dramatic Explosions in the Universe

Nearly 10 billion years ago in a galaxy known as PKS B1424-418, a dramatic explosion occurred. Light from this blast began arriving at Earth in 2012.Recently, the IceCube Neutrino Observatory at the South Pole found first evidence for a flux...

Has Political Correctness Gone Too Far?

Apparently not for the cry bullies and cowardly administrators at the University of Massachusetts, Amherst: UMass-Amherst students this week threw a mass temper tantrum to derail a forum that challenged the speech police. “The Triggering: Has Political Correctness Gone Too...

Worry and Regret and Time

Worry and regret form a pair in that each involves flight from the present; worry flees the present toward an unknown future, regret toward an unchangeable past. The door to Reality, however, is hinged on the axis of the Now....

An Indiscernibility Argument for Dualism: Does it Beg the Question?

Here is a simple indiscernibility argument for substance dualism, presented simply: 1. If two things are identical, then whatever is true of the one is true of the other, and vice versa. 2. It is true of me that I...

'Whose' and 'Of Which': How Punctilious is Too Punctilious?

Which of the following is correct? 'He presented an argument whose logical form is Modus Tollens.' 'He presented an argument the logical form of which is Modus Tollens.' The second. But it would be absurd to insist on a punctilio...

School days, school days

Q: Could you tell me the origin of the compound word “schoolteacher”? What is the reason for the redundancy? My first thought was that the phrase distinguished schoolteachers from Sunday school teachers. I later theorized that it might’ve come from the Germanic preference for compounds. Show More Summary

Birds of prey constrained in the beak evolution race

How birds' beaks evolved characteristic shapes to eat different food is a classic example of evolution by natural selection. However, new research from the Universities of Bristol, Sheffield, Madrid and York, published today in the journal...Show More Summary

Nanoparticles present sustainable way to grow food crops

Scientists are working diligently to prepare for the expected increase in global population -- and therefore an increased need for food production-- in the coming decades. A team of engineers at Washington University in St. Louis has found a sustainable way to boost the growth of a protein-rich bean by improving the way it absorbs much-needed nutrients. read more

Clay nanotube-biopolymer composite scaffolds for tissue engineering

The fabrication of a prototype tissue having functional properties close to the natural ones is crucial for effective transplantation. Tissue engineering scaffolds are typically used as supports which allow cells to form tissue-like structures essentially required for the correct functioning of the cells under the conditions close to the three-dimensional tissue. read more

Making precision medicine a reality: Genomics researchers unveil road map to disease origin

TUCSON, Ariz. - Researchers are one step closer to understanding the genetic and biological basis of diseases like cancer, diabetes, Alzheimer's and rheumatoid arthritis - and identifying new drug targets and therapies - thanks to work...Show More Summary

VIB/UGent researchers use viral particles to trap intact mammalian protein complexes

Belgian scientists from VIB and UGent developed Virotrap, a viral particle sorting approach for purifying protein complexes under native conditions. This method catches a bait protein together with its associated protein partners in virus-like particles that are budded from human cells. Show More Summary

Using oxygen to sterilize medical implants could save time and money

International researchers led by the University of Bath have demonstrated a cheap, effective and environmentally-friendly way to sterilise medical implants without changing their properties, in contrast to some techniques. This inexpensive...Show More Summary

Trauma in a bee

Jena (Germany) With the arrival of spring many insects leave their winter quarters. Presently swarms of the mining bee (Andrena vaga) emerge along sandy river valleys. These whitish-grey haired wild bees live in galleries and cavities in the ground. Show More Summary

CNIC Researchers identify a new signaling mechanism implicated in congenital aortic valve disease

Researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have demonstrated the crucial role of the NOTCH signaling pathway in the development of a fundamental heart structure, the heart valves. These valves ensure unidirectional bloodflow with each heartbeat, and open and close millions of times during a person's lifetime. read more

New data improve techniques for determining whether a jaw bone comes from a man or woman

The scientific breakthrough, carried out by researchers at UGR and the Spanish National Research Council, is of great significance to the field of biological anthropology. It also has further implications for paleoanthropology, paleodemographics, forensic science and orthodontics, among other disciplines. read more

Prion-like protein found in plants

CAMBRIDGE, Mass. - Whitehead Institute scientists have determined that a plant protein involved in the timing of flowering could in fact be a prion. This is the first time that a possible prion has been identified in plants. Infamous...Show More Summary

Spintronics for future information technologies

They thereby demonstrated that this class of materials is suitable for data processing based on spin. The work has been published in the renowned periodical Physical Review B and was selected as "Editor's Suggestion" article. read m...

Hormone and neurotransmitter systems disturbed in alcoholics' brains

The brain tissue of persons with alcohol dependence shows a variety of changes compared to non-alcoholic control persons. All alcoholics' brains share some characteristics, but some are exclusive to the brain tissue of anxiety-prone type 1 alcoholics or impulsive type 2 alcoholics, according to a recent study from the University of Eastern Finland. read more
