Operationalizing the local environment for replicator dynamics

by Artem Kaznatcheev in Evolutionary Games Group

Recently, Jake Taylor-King arrived in Tampa and last week we were brainstorming some projects to work on together. In the process, I dug up an old idea I’ve been playing with as my understanding of the Ohtsuki-Nowak transform matured. The basic goal is to work towards an operational account of spatial structure without having to […]... Read more »

An apple a day may keep the children away: Pesticides and sperm count

by Dr. Jekyll in Lunatic Laboratories

Ever hear that old saying an apple a day keeps the Doctor away? Well it might have the right idea, just the wrong person. New research investigating the relationship between eating fruit and vegetables containing pesticide residues and the quality of men’s semen has shown a link with lower sperm counts and percentages of normally-formed sperm. So for people wanting children it may be time to rethink that produce.... Read more »

Ovulation changes women’s desire for variety in products

by Dr. Jekyll in Lunatic Laboratories

We know that hormones affect who we are, even when we aren’t aware of it. In the past scientists have found that people who are hungry tend to buy more things, no surprise for those of us who have shopped hungry. However, new research shows that women seek a greater variety of products and services, specifically when they are ovulating.... Read more »

Viruses and the Nucleolus: Coronavirus N, Cytokinesis and Autophagy

by thelonevirologist in Virology Tidbits

The nucleolus is a subnuclear structure not surrounded by a membrane, which is disassembled during mitosis and reformed during late telophase via the interaction of nucleolar proteins with loci of ribosomal DNA. At this point, the inhibition of CDK1 leads to the resumption of RNA Polymerase I (RNA Pol I) dependent transcription of rDNA, resulting in the expression of the pre-rRNA (18S, 5.8S, and 28S, with internal and external transcribed spacers) and the recruitment of the processing machinery,........

Moths Fondly Remember Plant Species Where They Lost Their Virginity

by Elizabeth Preston in Inkfish



Think real estate decisions are hard for humans? Imagine if the house you lived in were also your singles bar, your babies' nursery, and your shelter from large animals trying to eat you. And, while you were growing up, your food source, as you nibbled away its floors and shingles.

Moths face all these pressures each time they settle down on a plant. That may be why at least one type of moth uses pleasant associations to help with its choices. The plant species where an individual loses........ Read more »

Shields Up! Lay In A Course For Mars

by Mark E. Lasbury in The 'Scope

Deflector shields allowed Star Trek and other sci-fi franchises to have long space battles. Without them, one good strike and everyone was dead – that wouldn’t lend itself to sequels.

We don’t need shields for space battles yet, but we do need them to get to Mars. Cosmic radiation will kill or injure every astronaut unless we can deflect the radiation away from the spacecraft. We’re just about to build real deflectors, and our teachers are the magnetic fields we find ........ Read more »

African-Americans Receive Heart Transplants at Hospitals With Poor Performance Track Records

by Jalees Rehman in The Next Regeneration

About five million people in the US suffer from heart failure, and approximately half of them die within five years of being diagnosed. Only about 2,500 hundred people a year receive a heart transplant – the treatment of last resort. A new heart can be life-saving, but it is also life-changing. Even under the best conditions, the surgery is complex, and recovery carries a heavy physical and emotional burden.

How time pressure improves decision making in emergency situations

by BPS Research Digest in BPS Research Digest

A new simulation of a complex, realistic disaster event suggests that time pressure facilitates better decision-making among emergency responders. The two-day training exercise, overseen by Liverpool’s Centre for Critical and Major Incident Psychology, looked at the impact of a hypothetical aeroplane crash over a city. Nearly two hundred professionals were split into different rooms based on the agency they belonged to (14 agencies in all, including police, transport, health and science adviso........ Read more »

Fixing 'leaky' blood vessels to combat severe respiratory ailments and, perhaps, Ebola

by Jalees Rehman in Fragments of Truth

When you get an infection, your immune system responds with an influx of inflammatory cells that target the underlying bacteria or viruses. These immune cells migrate from your blood into the infected tissue in order to release a cocktail of pro-inflammatory proteins and help eliminate the infectious threat. During this inflammatory response, the blood vessel barrier becomes “leaky.” This allows for an even more rapid influx of additional immune cells. Once the infection resolves, th........ Read more »

How to improve memory five times in less than an hour?

by Usman Paracha in SayPeople

Main Point:

You can enhance your memory nearly five times with the help of 45-60 minutes of sleep.

Published in:

Neurobiology of Learning and Memory

Study Further:

Memory is the power of retaining, remembering, and recalling past experiences and knowledge. Normally, new information moves away from the mind quite rapidly as we are prone to forget things. Every one of us wants to have a good memory. Researchers are working on new techniques to improve memory that may range from exer........ Read more »

Is anhedonia a key component of depression comorbid to autism?

by Paul Whiteley in Questioning Answers

Anhedonia: the inability to experience pleasure from activities usually found enjoyable.Although by no means an expert on anhedonia (or much else), I believe that it is a concept quite important when it comes to making a diagnosis of depression although the precise hows and whys of connecting anhedonia to other symptoms are still the source of some discussion [1].The paper from Vicki Bitsika & Christopher Sharpley [2] brings the concepts of anhedonia and depression into v........

Welcome to the wikipedia for neurons

by Dr. Jekyll in Lunatic Laboratories

While the brain might not have more connections than stars in the universe (sorry guys), it is still complex. In fact, someone I respect defined a neuroscientist as “someone who knows how little we know about the brain.” Despite the decades worth of data that has been collected about the billions of neurons in the brain, we still don’t know much. So to help scientists make sense of the vast amount of information we already collected, researchers used data mining to create neuroelectro.org,........ Read more »
