Hand-drawn maps imitating the printed maps in the 1st days of Hispano-American cartography

Eurekalert.org 

From the start of the colonisation, the Spanish Crown needed to know and represent the overseas territories under its control. In the last third of the sixteenth century, surveys were carried on to get to know this territories. Among these documents, the researchers have found a set of maps that are characterised by a peculiar style, as they try to imitate the style of maps that were drawn up in Europe in this period.

Study offers insight into how people judge good from bad

Eurekalert.org 

New research sheds light on how people decide whether behavior is moral or immoral. The findings could serve as a framework for informing the development of artificial intelligence and other technologies.

The first drywood termite known to use snapping stick-like mandibles to defend its colony

Eurekalert.org 

First-of-a-kind new species and genus of drywood termite was collected from two localities in Cameroon. With its soldier caste sporting a unique set of long, slender, stick-like 'jaws', the previously unknown insect is the first drywood termite known to rely on the so-called snapping mandibles as a defense strategy. The discovery, published in the open access journal ZooKeys, poses a whole set of questions about the origin of the termite and its key feature.

Robot masters human balancing act

Eurekalert.org 

By translating a key human physical skill, whole-body balance, into an equation, engineers at UT Austin used the numerical formula to program their robot Mercury.

Making mice a tiny bit more human to study preterm birth

Eurekalert.org 

Preterm birth remains a global epidemic linked to a lifetime of potential health complications. It also is difficult to study in living creatures -- especially the uniquely precise biology of preterm birth in humans. Researchers report in PLoS Biology successfully inserting just enough human DNA into transgenic laboratory mice that it allowed the team to study a unique part of human pregnancy compared to other animals.

Sleep research uncovers dire consequences to deprivation

Eurekalert.org 

Researchers at Michigan State University conducted the largest experimentally controlled study on sleep deprivation to date, revealing just how detrimental operating without sleep can be in everything from bakers adding too much salt to cookies to surgeons botching surgeries.



The faint glow of cosmic hydrogen

Eurekalert.org 

A study published recently in Nature magazine, in which Ana Monreal-Ibero, a researcher at the Instituto de Astrofísica de Canarias (IAC) is a participant, reveals the presence of a hitherto undetected component of the universe: large masses of gas surrounding distant galaxies.

New tool helps scientists better target the search for alien life

Eurekalert.org 

An EPFL scientist has developed a novel approach that boosts the chances of finding extraterrestrial intelligence in our galaxy. His method uses probability theory to calculate the possibility of detecting an extraterrestrial signal (if there is one) at a given distance from Earth.

University of Minnesota Medical School researchers have discovered how to slow aging

Eurekalert.org 

Previous research published earlier this year involving University of Minnesota Medical School faculty and Mayo Clinic investigators, showed it was possible to reduce the burden of damaged cells, termed senescent cells, and extend lifespan and improve health, even when treatment was initiated late in life. They now have shown that treatment of aged mice with the natural product Fisetin, found in many fruits and vegetables, also has significant positive effects on health and lifespan.

Whole-brain connectome maps teach artificial intelligence to predict epilepsy outcomes

Eurekalert.org 

Medical University of South Carolina (MUSC) neurologists have developed a new method based on artificial intelligence that may eventually help both patients and doctors weigh the pros and cons of using brain surgery to treat debilitating seizures caused by epilepsy. This study, which focused on mesial temporal lobe epilepsy (TLE), was published in the September 2018 issue of Epilepsia. This work also highlights how artificial intelligence is driving change in the medical field.

Cobra cannibalism more prevalent than previously thought

Eurekalert.org 

Researchers in South Africa's Kalahari Desert found a large male cape cobra devouring another smaller male of the same species. Surprised by the thought-to-be-rare event, they decided to investigate how common and widespread cannibalism was in cobras.

The rise of science from prehistory to the far future

Eurekalert.org 

(Springer) Infants are often dubbed 'young scientists' because in order to survive they need to find out about the world around them as quickly as possible. Some who never lose their childhood curiosity go on to become adult scientists. The Rise of Science charts and discusses the body of scientific knowledge that humanity has accumulated -- certainly one of our greatest achievements.

The immune system of the alpaca reveals a potential treatment for cancer

Eurekalert.org 

(Institute for Research in Biomedicine (IRB Barcelona)) The natural world often provides the answer to unsolved medical problems. On this occasion, the solution to a challenge posed by cancer has come about from the immune system of camelids. A study headed by the Institute for Research in Biomedicine (IRB Barcelona) and the Vrije Universiteit Brussel (VUB), in Belgium, describes a number of therapeutic tools that have the capacity to block the activity of EGF, a growth factor that is dysregulated in cancer cells.

Breaking supersymmetry

Eurekalert.org 

(Kanazawa University) Supersymmetry predicts a relationship between the fundamental particles fermions and bosons. An extended version of a pioneering model of non-relativistic supersymmetry -- the Nicolai supersymmetric fermion lattice model -- is studied. Previously, it was verified that supersymmetry of the model breaks down only when the adjustable constant g > g0 ? 4/π. A researcher at Kanazawa University removed the restriction on g and showed that the extended version of the Nicolai supersymmetric... Читать дальше...

Secondary forests have short lifespans

Eurekalert.org 

Secondary forests only last an average of 20 years. The finding presents a major problem for large-scale restoration policy, which often focuses on commitments to restore a certain number of hectares by a given year. But the benefits of restoration depend on those forests persisting. It takes much longer than 20 years for a secondary forest to absorb large amounts of carbon, or to provide habitat for many forest species, research shows.

Black holes ruled out as universe's missing dark matter

Eurekalert.org 

If dark matter consists of a plethora of primordial black holes, then their gravitational lensing -- magnifying and brightening distant objects -- should be detectable. UC Berkeley physicists analyzed 740 known supernovas to find the handful that should have been magnified and brightened by black holes, and found none. This puts a strong upper limit, 40, on the percent of dark matter that can consist of black holes, and suggests that none of it is.

Professor, MSD high school senior collaborate on homicide trends

Eurekalert.org 

An FAU professor and a high school senior from MSD have published a study on homicide rates in Baltimore and New York City. They note marked differences between these 'peer' cities according to 19 population-based characteristics from the US Centers for Disease Control and Prevention. The root causes for these differences are complex and multifactorial, and raise several major clinical and contemporary medical policy issues. The vast majority of these US homicides are attributable to firearms.
