10:05 AM | Working at a treadmill desk boosts your memory and concentration, researchers claim
Image from Labonté-LeMoyne et al.We're told sitting is the new smoking and that we should consider working at standing desks, or perhaps better still, treadmill desks. Indeed, the health benefits of treadmill desks are indisputable, say neuroscientists in Canada, led by Élise Labonté-LeMoyne. More contentious, these researchers explain, is the evidence for the psychological effect of such set-ups on our work performance.For instance, one study found impaired maths […]

8:00 AM | Would You Have Sex For Science?
Who volunteers to have sex in a laboratory? I was struck by this question when reading about an experimental study of ideal sexual positions for men with back pain. For the purpose of the research, couples were filmed using motion capture and infra-red technology while they had sex.The researchers were in a separate booth where they could hear, but not see, the participants. Electrodes were used to record muscle activity in certain parts of the body, to get an idea of force. read more

6:12 AM | Isolated Attosecond Pulse Generation At The Carbon K-edge - First Proof
In a recent study, "Spatiotemporal isolation of attosecond pulses in the soft X-ray water window " published in Nature Communications by the Attoscience and Ultrafast Optics Group, led by ICREA Professor at ICFO Jens Biegert, the generation of isolated attosecond pulses at the carbon K-edge at 284 eV (4.4 nm), within the water window range, was achieved. Carbon is one of the most abundant elements in the Universe and the building block of life on earth. It is a fundamental element for both […]

5:09 AM | Alzheimer's: Tau, Not Amyloid, Is The Primary Driver
An examination of over 3,600 postmortem brains has concluded that the progression of dysfunctional tau protein drives the cognitive decline and memory loss seen in Alzheimer's disease. That means amyloid, the other toxic protein that characterizes Alzheimer's and builds up as dementia progresses is not the primary culprit.There has been an ongoing debate about the relative contributions of amyloid and tau to the development and progression of cognitive dysfunction in Alzheimer's but the […]

4:31 AM | Obese Women With Gestational Diabetes Who Add Weight 40X More Likely To Get Type 2 Diabetes
New research published in Diabetologia shows that in women who have developed gestational diabetes mellitus (GDM) during pregnancy, being obese before the pregnancy and putting on more weight after it massively increases the risk of later developing type 2 diabetes (T2D). read more

2:32 AM | Canadian Immigrants Are In Better Health Than Citizens - Until They Stay A While
Research has shown that the health of immigrants is generally better than that of citizens of their host country, at least on their arrival and for some time afterwards. But a team of researchers in Montreal has found that this is not true of all groups of immigrants; children and older people, for example, may be exceptions. "Our analysis suggests that immigrant health policies should not be 'one size fits all' in type, and that they need to take account of immigrants' ages and the indicators […]

2:32 AM | In Latin America, Educated Women Having Kids Outside Marriage Are Increasingly Popular
In Latin America, consensual (common-law) unions are traditionally associated with poorer or indigenous populations. But recent research is turning this conventional wisdom on its head, finding that that in the past 30 years or so consensual unions have become increasingly popular throughout Latin America, including in higher-income groups. In certain countries, such as Panama, common-law partnerships are now as widespread as in Quebec. read more

12:32 AM | Atlantic Meridional Overturning Circulation Shows 10 Years Of Changing UK Winters
A 10 year project to observe and analyze regular data about ocean circulation and how it impacts on Britain’s climate has provided new insight into Atlantic Meridional Overturning Circulation (AMOC), a major system of currents in the North Atlantic.10 years is too short a time to be meaningful but it is an important milestone. Since 2004, the project team has been monitoring the AMOC at 26.5N degrees, near where it carries its maximum heat, using instruments moored at 30 locations across […]

8:21 PM | Wandering Jupiter, Did Our Solar System Once Have Super-Earths?
We may have Jupiter to thank for our unusual solar system. Before the inner planets we now call  Mercury, Venus, Earth, and Mars formed, a great inward-and-then-outward journey that Jupiter made early in the solar system's history may have torn apart a number of super-Earths - planets larger than Earth but smaller than Neptune - and caused their giant remnants to fall into the sun billions of years ago.read more

7:02 PM | The neurological basis for anorexia nervosa
Most of us know about dieting, and if not first hand, have seen in the news or from friends how hard sticking to a diet long-term can be. This is because adults (regardless of their weight_ resolve to lose weight. Yet, more often than not, that chocolate lava cake is too enticing and that resolve vanishes. This behavior […]

5:46 PM | Facial Movements Of Unborn Babies Show Effects Of Maternal Smoking?
High-definition scans lead a team of researchers to conclude that the harmful effects of smoking during pregnancy may be reflected in the facial movements of mothers' unborn babies.In the small pilot study, the scholars observed 4-d ultrasound scans and found that fetuses whose mothers were smokers showed a significantly higher rate of mouth movements than the normal declining rate of movements expected in a fetus during pregnancy. The researchers suggested that the reason for this might be […]

5:19 PM | End Of Latency: Musicians Rehearse 1,000 Miles Apart With No Delay
Latency is so ingrained into modern communication we almost forget about it but in live or recorded events, like performances or rehearsals over a long distance, it is crippling. When recording a soundtrack over a pre-recorded base, the latency is perceptible to the human ear if a delay of 15-20 milliseconds occurs - the track seems displaced from the rest, giving the sense of being poorly played. To resolve displacement over long distances, elements such as sound capture, sound coding and […]

4:57 PM | Phonons Controlled: Magnets Manipulate Sound Too
Researchers have discovered proof that acoustic phonons, the elemental particles that transmit both heat and sound, have magnetic properties. In a new paper, the authors describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by 12 percent. But because the phonons reacted to the magnetic field, the particles must be sensitive to magnetism.  read more

4:31 PM | Migraine Headaches And Carpal Tunnel Syndrome Linked
Patients with carpal tunnel syndrome are more than twice as likely to have migraine headaches, according to data derived from nearly 26,000 Americans responding to a national health survey. Among other questions, participants were asked whether they had had carpal tunnel syndrome during the past year or "severe headache or migraine" during the past three months. Patients with carpal tunnel syndrome have symptoms such as hand numbness and weakness, resulting from pressure on the median nerve in […]

4:23 PM | Cosmic Building Block Dust From An Ancient Supernova Found
One of astronomy's big questions is why galaxies forming as recently as 1 billion years after the Big Bang contain so much dust. The leading hypothesis is that supernovae, stars that explode at the end of their lives, contain large amounts of metal-enriched material that, in turn, harbors key ingredients of dust, like silicon, iron and carbon.read more

4:09 PM | Geoengineering: Ocean Pipes Would Make Climate Worse
To combat possible climate change due to greenhouse gases, a mix of alternative energy sources (except nuclear for the United States) and geoengineering schemes have been proposed. One idea proposes that ocean pipes could facilitate direct physical cooling of the surface ocean by replacing warm surface ocean waters with colder, deeper waters. A new study from a group of Carnegie scientists determines that these types of pipes could actually increase global warming quite

4:00 PM | Nova Vulpeculae 1670 - Colliding Stars Explain 17th Century Explosion
In 1670, the greatest astronomers, including Cassini and Hevelius, the father of lunar cartography, documented the appearance of a new star in the skies. Hevelius described it as nova sub capite Cygni — a new star below the head of the Swan — and now it is officially known it by the name Nova Vulpeculae 1670.  It lies within the boundaries of the modern constellation of Vulpecula (The Fox), just across the border from Cygnus (The Swan) and is also referred to as Nova Vul 1670 […]
