Darwin convinced the world, but was he the first to describe evolution?
2015-04-20
(Press-News.org) A new review of the ideas and work of Patrick Matthew, a little-known antecedent of Charles Darwin, argues that Matthew is under-appreciated even though he described the idea of large-scale evolution by natural selection decades before Darwin did. Some of his ideas were different from Darwin's but are equally valid.
"Patrick Matthew was a fascinating character--strong-willed and fiercely independent," said Dr. Michael Weale, author of the Biological Journal of the Linnean Society article. "Darwin used detailed, methodical force of argument to convince the world of evolution by natural selection. Matthew's reasoning was brilliant in a different way--a concise piece of deduction that is well worth reading even today." Dr. Weale has set up a website that acts as an online repository of the writings by and regarding Patrick Matthew.

For many students or junior academics--and even for senior investigators--initiating a new piece of research can be a daunting experience, and they often do not know where or how to begin. A recent Accounting and Finance article offers a simple new research tool that can act as a template designed for pitching research ideas to mentors or other experts.
The two-page pitching template includes 4 preliminary components: working title, research question, key papers, and motivation. Next is a '3-2-1 countdown' that is based on 3 elements - idea, data, and tools; 2 questions ...

Among soft-bodied cephalopods, vampire squid live life at a slower pace. At ocean depths from 500 to 3,000 meters, they don't swim so much as float, and they get by with little oxygen while consuming a low-calorie diet of zooplankton and detritus. Now, researchers reporting in the Cell Press journal Current Biology on April 20 have found that vampire squid differ from all other living coleoid cephalopods in their reproductive strategy as well.
While other squid reproduce all at once late in their lives, vampire squid appear to alternate between reproductive and resting ...

Household pets can transmit infection to people, especially those with weak immune systems, young children, pregnant women and seniors, according to an article in CMAJ (Canadian Medical Association Journal). Health care providers and pet owners should be aware of this risk to prevent illness in vulnerable people.
Surveys suggest that the general public and people at high risk for pet-associated disease are not aware of the risks associated with high-risk pet practices or recommendations to reduce them; for example, 77% of households that obtained a new pet following a ...

La Jolla, Calif., April 20, 2015 - A new research study has shown that pancreatic cancer cells can be coaxed to revert back toward normal cells by introducing a protein called E47. E47 binds to specific DNA sequences and controls genes involved in growth and differentiation. The research provides hope for a new treatment approach for the more than 40,000 people who die from the disease each year in the United States.
"For the first time, we have shown that overexpression of a single gene can reduce the tumor-promoting potential of pancreatic adenocarcinoma cells and reprogram ...

COLUMBUS, Ohio--As new medical diagnostics become available, researchers are increasingly discovering situations in which pets can transmit diseases to humans--especially when an owner's immune system is compromised.
At The Ohio State University and partner institutions, researchers have compiled the latest information from more than 500 studies worldwide to make recommendations on how families can minimize the risk of disease transmission by choosing the right type of pet, or by making small changes in how they enjoy the pets they already have.
The review was published ...

A new diagnostic method, namely spectral histopathology, facilitates marker-free detection of individual subtypes of lung cancers. It was developed by researchers at the PURE consortium at Ruhr-Universität Bochum (RUB). They have successfully applied it in collaboration with clinicians at the Ruhrlandklinik in Essen. It is an automatable imaging process which, by classifying specific forms of lung cancer, facilitates a prognosis regarding a tumour's aggressiveness. The team, headed by RUB Prof Dr Klaus Gerwert, compares the results of traditional diagnostic procedures ...

CLEMSON, S.C. -- In a groundbreaking achievement led by an international team that includes Clemson scientist Chris Saski, the intricately woven genetic makeup of Upland cotton has been decoded for the first time in the ancient plant's history.
Saski participated in sequencing the genome, which is a crucial stepping-stone toward further advancements of understanding the inner workings of one of the most complex and treasured plants on the planet.
The future implications of Saski's research in the short and long terms are both financial and holistic. Upland cotton, which ...

CORVALLIS, Ore. - Researchers at Oregon State University have invented a new technology that can increase the bandwidth of WiFi systems by 10 times, using LED lights to transmit information.
The technology could be integrated with existing WiFi systems to reduce bandwidth problems in crowded locations, such as airport terminals or coffee shops, and in homes where several people have multiple WiFi devices.
Experts say that recent advances in LED technology have made it possible to modulate the LED light more rapidly, opening the possibility of using light for wireless ...

NEW YORK (April 20, 2015) -- Genomic studies have illuminated the ways in which malfunctioning genes can drive cancer growth while stunting the therapeutic effects of chemotherapy and other treatments. But new findings from Weill Cornell Medical College investigators indicate that these genes are only partly to blame for why treatment that was at one point effective ultimately fails for about 40 percent of patients diagnosed with the most common form of non-Hodgkin Lymphoma.
The study, published April 20 in Nature Communications, suggests that global changes in cancer ...

A rigorous analysis of antimalarial drug quality conducted in Cambodia and Tanzania found no evidence of fake medicines, according to new research published in the American Journal of Tropical Medicine and Hygiene.
But researchers warn that routine surveillance is crucial as poor quality medicines exist, leaving malaria patients at risk of dying and increasing the risk of drug resistance.
Previous reports had suggested that up to one third of antimalarials could be fake. Researchers from the Artemisinin-based Combination Therapy (ACT) Consortium at the London School ...
