Galantamine and Alzheimer's Disease: An extract of daffodils improves memory loss.
Rajini Rao originally shared:
Daffodils and Dementia

✿ It's spring time in Maryland, and in the words of the poet Wordsworth, my heart dances with the daffodils. Through the long winter, I conjured up memories of these cheerful blooms in my mind:

For oft, when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.

✿ But an estimated 44 million people world wide who suffer from Alzheimer's disease are robbed of their memories by a progressive dementia. As the 6th leading cause of death in the U.S., Alzheimer's cannot be cured or prevented. One of the handful of drugs available to improve memory loss in patients is galantamine, which is extracted from the leaves and bulbs of daffodils (Narcissus) and snowdrops (Galanthus). These extracts have been in use since ancient times. In Homer's Greek epic, Odysseus is said to have used snowdrops to clear his mind bewitched by Circe. In the 1950s, a pharmacologist observed inhabitants of a remote Bulgarian village rubbing the extracts on their forehead and shortly after, the drug was approved for medical use. Galantamine increases the action of the neurotransmitter acetylcholine in some parts of the brain, both by making the receptor more sensitive to its action and by slowing down its removal. The drug has other interesting properties: it is said to promote lucid dreaming, improve sleep quality, memory loss in brain damage, and some autistic symptoms (  

✿ No drug has yet stopped the inexorable progress of Alzheimer's. Early intervention is key to effective treatment: in my lab, for example, we are studying endosomal pathology which is the earliest sign of problems at the cellular level ( Yet lack of funding stifles productive research. As Newt Gingrich points out in his recent Op-Ed for New York Times, we spend only 0.8% of the estimated 154 billion dollars of annual medical costs related to Alzheimer's disease on research to cure or prevent it

Competitive Desalination -- It's not a sport; but it is a very cool way to get international teams to go head-to-head, solving one of the vexing problems of modern life: How to make brackish #water  drinkable. Oh, and there's something like $200k in #prize  money. A bit more in grants.  Read on!
Three Teams Take Top Honors in Desal Prize At the Bureau of Reclamation's Brackish Groundwater National Desalination Research Facility
ALAMOGORDO, N.M. - The Bureau of Reclamation and the U.S. Agency for International Development have announced the April 9 to 11 Desal Prize winners— +Massachusetts Institute of Technology (MIT)/+Jain Irrigation Systems, +UTEP- The University of Texas at El Paso Center for Inland Desalination System, and Green Desal.

Five finalist innovator teams had competed for $200,000 in prize funds in head-to-head demonstrations at Reclamation’s Brackish Groundwater National Desalination Research Facility in Alamogordo. However, only the top three teams will receive grant funds totaling $400,000 to implement pilot projects in late summer or early fall with small-holder rural farmers in a USAID mission region.

“The Bureau of Reclamation was proud to host this international competition at the Brackish Groundwater National Desalination Research Facility, which included 68 applications from 29 countries,” Reclamation Commissioner Estevan López said. “Providing a sustainable water supply is important for the west, the country and the world. The knowledge gained from this competition will not only assist in the goals of the prize competition, it will inform brackish groundwater treatment technologies here in the United States.”

The Desal Prize is a three-phase, incentivized competition that challenged worldwide innovators to create cost-effective, energy efficient and environmentally sustainable desalination technologies that can provide potable water for humans and water for crops in developing countries. After rigorous testing and evaluation by a panel of expert judges, the following are the Desal Prize top winners:

First Place: MIT and Jain Irrigation Systems designed a photovoltaic-powered electrodialysis reversal (EDR) system that desalinates water-using electricity to pull charged particles out of the water and further disinfects using ultraviolet rays. The system was designed for low energy consumption, limiting costs especially in off-grid areas.

Second Place: University of Texas at El Paso (UTEP) Center for Inland Desalination System designed a Zero Discharge Desalination (ZDD) technology that reduces water waste in the desalination of groundwater by conventional processes. Electrodialysis uses voltage to remove undesirable ions from water.

Honorable Mention: Green Desal, a team comprised of the Asian Institute of Technology & Management, National Center for Agricultural Research and Extension, State University of Ponta Grossa, Technion-Israel University of Technology, and University of North Texas, developed a high-percent recovery system that integrates proven technologies in reverse osmosis, ion exchange, nano-filtration, re-mineralization and disinfection.

The Desal Prize, launched in partnership with the Swedish International Development Cooperation Agency and the Ministry of Foreign Affairs of the Kingdom of The Netherlands, is the second “call” under the Securing Water for Food Grand Challenge for Development. The “first” call focused on innovation in later stages of the innovation lifecycle (market-driven product/business development and scaling/commercial growth).

From April 6-12, five Finalist teams descended on the U.S. Bureau of Reclamation's Brackish Groundwater National Desalination Research Facility to compete in a head-to-head demonstration of their innovative desalination technologies.

Great news. I grew up, in large part, on islands: In places where cisterns to capture rainwater were a necessity, and desalination plants took up ugly acreage near pristine shorelines...

Short bursts of showers, bottled drinking water: Par for course.

It'd be fantastic to see this tech developed to a degree that life, in the middle of the ocean, became even just a bit easier, for everyone...

GOOD LUCK, Participants! And: Thank you!

Caesalpinia bonduc L. is an important medicinal plant threatened by overexploitation. In the present study, the impact of climate on seed morphology, germination capacity, seedling and plant growth of C. bonduc were evaluated. A total of 2000 seeds were collected in Sudanian and Guinean climate zones of Africa and their length,
width, thickness, weight and color were recorded. A hierarchical classification and canonical discriminant analysis were applied to the above traits of seeds from the different climatic zones. An analysis of variance with repeated measures was applied to seeds morphotypes identified by the hierarchical classification to test for the effect of these morphotypes on seed germination, seedling and plant growth. Hierarchical classification helped to identify four seed morphotypes. Canonical discriminant analysis performed on these morphotypes revealed highly significant differences. Morphotypes 1 and 3 comprised green seeds mainly from Sudanian zone while morphotypes 2 and 4 gathered grey seeds mainly from Guinean zone. Morphotype 3 had the longest seeds while the shortest seeds were from morphotype 1. The heaviest seeds were found in morphotype 4 whereas the lightest ones were from morphotype 1. Seeds of morphotype 4 were the thickest and widest, while the slimmest and most narrow ones were grouped in morphotype 1. Moprhotype 3, consisting of large green seeds mainly from Sudanian zone, was superior in terms of seedling and plant growth among all morphotypes and should be the best choice for planting purposes of the species.

There are 111 essentially different ways to decompose a regular octagon neatly into convex, centrally symmetric tiles. What exactly does this mean? Find out more below.
Tiling an octagon with centrally symmetric pieces

It is easy to cut an equilateral triangle into four smaller equilateral triangles, or to cut a square into four smaller squares, or to cut a regular hexagon into six equilateral triangles (think of a Trivial Pursuit playing piece). Less obviously, it is possible to cut a regular octagon into polygon-shaped pieces that are both centrally symmetric and convex. Some of these are illustrated in this picture.

The picture comes from the recent paper Decompositions of a polygon into centrally symmetric pieces by Júlia Frittmann and Zsolt Lángi ( The introduction of the paper gives a brief survey of some related problems. For example, it is trivial to cut a square into a set of triangles of the same area as each other, as anyone who has tried to cut a square piece of bread into triangles will know. (Note, however, that the resulting triangles will probably not be centrally symmetric.) Given this, it may be surprising to discover that that P. Monsky proved in 1970 that it is impossible to cut a square into an odd number of triangles, all of the same area.

Frittmann and Lángi's paper illustrates all 111 irreducible edge-to-edge decompositions of a regular octagon into convex polygonal pieces (tiles), where each tile is rotationally symmetric about its centre. The 18 decompositions shown in the picture are among the 111 irreducible decompositions.

In order for this classification to make complete sense, some terms need to be defined. A decomposition is called edge-to-edge if each edge of each tile either lies in the boundary of the surrounding polygon, or if it meets the edge of some other tile along the entire length of the edge. A shape is called convex if, whenever two distinct points are chosen within the shape, the straight line connecting the two points lies entirely within the shape. A decomposition with n tiles is called irreducible if, whenever at least 1 but at most n–2 tiles are removed from the decomposition, the remaining tiles form a non-convex shape. 
If A and B are tilings of the same polygon, we say that A is equivalent to B if there is a one to one correspondence between the set of tiles of A and the set of tiles of B, in such a way that two tiles of A touch each other in the same way that the corresponding two tiles of B touch each other. [Precise definition for mathematicians: two tilings are equivalent if the face lattices of the corresponding CW-decompositions are isomorphic.] There are infinitely many ways to tile an octagon under the constraints mentioned above, but there are only finitely many different ways up to equivalence. 

The main result of Frittmann and Lángi's paper generalizes this result to the case of a polygon with an even number, 2k, of sides, where k is at least 4. It turns out that in order for such a decomposition to be possible at all, the big polygon needs to be centrally symmetric. The authors show that up to equivalence, there will be a finite number of irreducible edge-to-edge decompositions of a centrally symmetric polygon into centrally symmetric, convex, polygonal parts. For an octagon, this number is 111, and G. Horváth proved in 1997 that the corresponding number for a hexagon is only 6. In their paper, Frittmann and Lángi give an upper bound for the number of decompositions for larger values of k.

It would be interesting to know what happens in the case where the big polygon has an odd number of sides. As I mentioned in the first paragraph, it is clearly possible to do something analogous for an equilateral triangle, although I don't know what would happen in the case of, say, a regular pentagon.

I mentioned CW decompositions above. These are associated to a CW complex, which is an important type of topological space. The “CW” is not somebody's initials, or an American TV channel, but rather stands for “closure-finite” and “weak topology”. The definition of a CW complex is rather technical, but it can be found here:

Seismometer - indispensable Instrument at times of earthquakes

At the moment, the entire Himalayan region is slowly recovering from a devastating earthquake that registered the magnitude 7.8 on Richter Scale.

In a tragic event caused by an earthquake, a simple instrument plays a key role in recording the shocks, estimating its power while assigning a corresponding number on the Ritcher Scale and above all calculating the epicenter of the earth quake. It is the seismograph.

A seismograph consists of a seismometer that is in contact with the ground - and then record the movement.

The following animation uses a mechanical seismoter fixed the ground.

You can read more on that here:

A few weeks ago physicists reported that they'd found what might be intelligent messages in extra-galactic fast radio bursts (FRBs) detected by radio telescopes. They ignored the even stranger signals similar to FRBs, known as Perytons. The signals' namesake, Peryton, is a mythical flying elk that casts the shadow of a human.
The Perytons were particularly odd because they seemed to come from all directions at once. A week later, the mysterious origin of the Perytons was discovered.

NurdRage has some of the most educative chemistry experiment videos on YouTube. In this one he presents various interesting chemistry topics: oxidation states, coordination chemistry, and comproportionation.
What I particularly like about the NurdRage videos:
- the experiments are well-prepared and thought out in minute detail.
- the commentary is clear and contains all the important scientific facts.
- the presentation style is extremely clear and informative, so the experiment is very easily rerproducible.
- no dumbing-down, no hand-waving, no BS.
