180,000 bites later… we may have a trap for bedbugs
A brave biologist who endured 180,000 bedbug bites over a five-year period has helped uncover the chemical cocktail needed to lure and trap these pesky parasites before infestation.

The ability to create primates with intentional mutations could provide powerful new ways to study complex and genetically baffling brain disorders.
The ability to create primates with intentional mutations could provide powerful new ways to study complex and genetically baffling brain disorders.
"Last November, the female monkey twins, Mingming and Lingling, were born here on the sprawling research campus of Kunming Biomedical International and its affiliated Yunnan Key Laboratory of Primate Biomedical Research. The macaques had been conceived via in vitro fertilization. Then scientists used a new method of DNA engineering known as CRISPR to modify the fertilized eggs by editing three different genes, and they were implanted into a surrogate macaque mother. The twins’ healthy birth marked the first time that CRISPR has been used to make targeted genetic modifications in primates—potentially heralding a new era of biomedicine in which complex diseases can be modeled and studied in monkeys."

Engineered vaginas grown in women for the first time 10 April 2014 by Catherine de Lange
Tissue engineered hearts and lungs may be still at the laboratory stage, but replacement vaginas made from the patient's own cells have been around for a while. A paper in the Lancet confirms they continue to work years after surgery.
The four patients in the study had Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome, which affects women who are genetically and hormonally normal but have an absent or greatly shortened vagina. MRKH may also produce a missing or defective cervix and uterus. Sex is usually painful for women with the condition and more than half a million are affected worldwide.

Hormone Affects Distance Men Keep from Unknown Women They Find Attractive: Oxytocin May Promote Fidelity
Hormone Affects Distance Men Keep from Unknown Women They Find Attractive: Oxytocin May Promote Fidelity
ScienceDaily (Nov. 13, 2012) — Men in committed relationships choose to keep a greater distance between themselves and an unknown woman they find attractive when given the hormone oxytocin, according to new research in the November 14 issue of The Journal of Neuroscience. The findings suggest oxytocin may help promote fidelity within monogamous relationships.

Blind mole rats may hold key to cancer
Blind mole rats may hold key to cancer
The blind mole rat is a long-lived and cancer resistant rodent.

Rodents' cells commit mass suicide when overcrowded, preventing uncontrollable proliferation.
Rodents' cells commit mass suicide when overcrowded, preventing uncontrollable proliferation.
There's more than one way for long-lived subterranean rodents to avoid cancer, and they might hold cellular clues to effective treatments in humans.
Cell cultures from two species of blind mole rat,Spalax judaei and Spalax golani, behave in ways that render them impervious to the growth of tumours, according to work by Vera Gorbunova at the University of Rochester in New York and her colleagues1. And the creatures seem to have evolved a different way of doing this from that observed in their better known and similarly cancer-resistant cousin, the naked mole rat (Heterocephalus glaber).

One test may 'find many cancers'
By James Gallagher
Health and science reporter, BBC News
Targeting just one chemical inside cancerous cells could one day lead to a single test for a broad range of cancers, researchers say.
Targeting just one chemical inside cancerous cells could one day lead to a single test for a broad range of cancers, researchers say.
The same system could then be used to deliver precision radiotherapy.
Scientists told the National Cancer Research Institute conference they had been able to find breast cancer in mice weeks before a lump had been detected.

One Step Closer to Rollable, Foldable E-Devices
One Step Closer to Rollable, Foldable E-Devices
ScienceDaily (Oct. 30, 2012) — The next generation of electronic displays -- e-Readers, smartphones and tablets -- is closer thanks to research out October 31 from the University of Cincinnati.
Advances that will eventually bring foldable/rollable e-devices as well as no pixel borders are experimentally verified and proven to work in concept at UC's Novel Devices Laboratory. That research is published this week in the journal Nature Communications.
The UC paper, "Bright e-Paper by Transport of Ink through a White Electrofluidic Imaging Film," is authored by College of Engineering and Applied Science doctoral students Matthew Hagedon, Shu Yang, and Ann Russell, as well as Jason Heikenfeld, associate professor of electronic and computing systems. UC worked on this research with partner: start-up company Gamma Dynamics.
Could We One Day Switch Off Bad Habits in Our Brains?
Could We One Day Switch Off Bad Habits in Our Brains?
Imagine one day being able to consult with a doctor about “switching off” your smoking habit with a day of outpatient surgery.
That’s the possibility raised by a new studyconducted by MIT neuroscientists aimed at finding the master switch in the brain that controls habits. Researchers found that a small region of the brain’s prefrontal cortex, where most thought and planning occurs, is responsible for moment-by-moment control of which habits are switched on at a given time.

ScienceDaily (Oct. 2, 2012) — Greenhouse gas emissions up to now have triggered an irreversible warming of Earth that will cause sea levels to rise for thousands of years to come, new research has shown Irreversible Warming Will Cause Sea Levels to Rise for Thousands of Years to Come, New Research Shows
ScienceDaily (Oct. 2, 2012) — Greenhouse gas emissions up to now have triggered an irreversible warming of Earth that will cause sea levels to rise for thousands of years to come, new research has shown Irreversible Warming Will Cause Sea Levels to Rise for Thousands of Years to Come, New Research Shows
The results come from a study, published today (Oct. 2) in IOP Publishing's journal Environmental Research Letters, which sought to model sea-l
evel changes over millennial timescales, taking into account all of Earth's land ice and the warming of the oceans -- something which has not been done before.
The research showed that we have already committed ourselves to a sea-level rise of 1.1 metres by the year 3000 as a result of our greenhouse gas emissions up to now. This irreversible damage could be worse, depending on the route we take to mitigating our emissions.
If we were to follow the high A2 emissions scenario adopted by the Intergovernmental Panel on Climate Change (IPCC), a sea-level rise of 6
.8 metres could be expected in the next thousand years. The two other IPCC scenarios analysed by the researchers, the B1 and A1B scenarios, yielded sea-level rises of 2.1 and 4.1 metres respectively
