3 Central role of water in biology

4 protein Excludes solutes, particles

5 gel gel Bulk Bulk water water plus plus particles particles Exclusion Exclusion Zone Zone EZ EZ µm µm

6 200 µm Another example

7 Basic finding confirmed Felix Blyakhman (Ural State Univ) Wei-Chun Chin (U. Cal. Merced) Toshio Hirai (Shinshu University) Mark Banaszak Holl (Univ. of Michigan) Tom Lowell (Vermont Photonics) Diedrich Schmidt (Tsukuba) Gerhard Artmann (Aachen) David Maughan (U. Vermont) Miklos Kellermayer (Budapest) Fettah Kosar (Harvard) Jacques Huyghe (Eindhoven) Nikolay Bunkin (Moscow) Federico Carpi (London) etc.

8 Getting to the basis Questions to Answer Is the exclusion phenomenon general? Does it really arise from water ordering? Can water ordering explain anomalies? What energy creates this order? Might these findings apply to health?

9 Question #1: Generality Surfaces: gels, polymers, biological surfaces, monolayers Solutes excluded: down to mw 100 and lower

10 Small solutes excluded ph-sensitive dye(s) H + H + Nafion dye excluded H +

11 Generality many solutes excluded many hydrophilic surfaces generate exclusion zones

12 Question #2 Is this zone physically different from bulk water? EZ

13 Evidence that exclusion-zone (EZ) water is physically different from bulk water EZ water molecules more constrained (NMR) EZ molecules more stable (infrared radiation) EZ has negative charge (electrical potential) EZ absorbs at 270 nm (light-absorption spectrum) EZ is more viscous (falling ball viscometry) EZ molecules aligned (polarizing microscopy) EZ molecular structure different (IR absorption) EZ optical properties different (refractive index) Zheng et al., Adv. Colloid and Interface Sci, 127: 19-27, 2006 Chai et al., J Phys Chem, 112: , 2008 Zheng et al., J. Coll. Interface Sci, 332: , 2009 Yoo et al. J. Phys. Chem. Letters 2: , 2011

22 Summary, so far may extend far Liquid crystalline Negative charge very Excludes solutes (Non-dipolar?) Fourth phase of water? (Sir Wm. Hardy, 1912)

23 Summary, so far may extend far Liquid crystalline Negative charge very Excludes solutes (Non-dipolar?) Fourth phase of water? (Sir Wm. Hardy, 1912)

24 Non-dipolar EZ Structure? Negative charge (dipoles neutral) 270-nm absorption (ring-like structures) Structure should have precedent

25 Precedent: ICE remove protons: negative charge; non solid

26

27 NOT H 2 O H 3 O 2

28

29

30 Advantages of Non-dipolar EZ Precedent Negative charge Ring-like structures (270-nm absorption) Able to accommodate helical structures Crystal-like structure can be solidified

31 Freeze-dry: Solid EZ water at room temperature Elia et al. WATER 2013 Elia et al. (in press)

32 Hypothesis: Information stored in EZ Water

33 Generic nucleator surface has no info

34 No information

35 Real nucleator surface contains info

36 Information from nucleating surface Defects project over many EZ layers INFORMATION

37 Another way of imparting information:

38 Electromagnetic energy Resonant vibratory modes Information out

39 Input Electromagnetic Energy can CREATE Information

40 EM waves can impact particular oxygen atoms Each oxygen five oxidation states Huge information-storage capacity

41 Will information storage in EZ water replace conventional info storage? Will information storage in EZ water impact health?

42 EZ layers

43 IR spectra liquid water

44

45 + uv

46

47 Answer to Question #2 Is EZ physically distinct from bulk? Yes Layered honeycomb structure with many implications

48 Question #3: Can crystalline water explain counter-intuitive anomalies? What behavior do we expect from a crystal?

49 Crystalline elements stick together

50 gelatin dessert (95% water) Why doesn t the water dribble out?

51 M Nydén, N Lorén, M Rudemo and M Kvarnström, Chalmers, Sweden

52 Crevices are filled with EZ water EZ water is gel-like.

53 Crystals can be pretty stiff

54 Water forming a bridge? Water forming a bridge? Elmar Fuchs, Wetsus

55 Water structure stiff enough to keep bridge from collapsing

56 Answer to Question #3 Yes Liquid crystalline water explains (many) anomalies

57 Question #4 What charges the water battery? (Incident radiant energy)

58 3.2 Most powerful: infrared 0 EZ-size ratio Wavelength (nm)

59

60 hydrophilic material EZ water

61 Answer to Question #4 Energy? EZ buildup powered by photonic energy Orders water Charges the water battery

62 Can this energy be harvested?

63 Energy can be harvested Nafion tube or PAA-gel tube water

64

65 nafion exclusion zone exclusion zone nafion

66 Polyacrylic acid gel PAA PAA gel gel EZ EZ PAA gel EZ EZ EZ Light 5x velocity Light: 5x speed increase

67 work done -- energy required energy absorption NECESSARY water transduces light energy

68 E = H 2 O

69 Question #5 Is all of this important for health? Foundational for any/all science involving water, molecules, and light Foundational for biological function, health

70 Does Human Biology Use Radiant Energy?

71

72 Pedro Cabrales UCSD

73 Radiant energy drives flow Might radiant energy help drive blood flow?

74 Absorbed external energy may assist blood flow* *Mice: flow continues 1 hour post mortem

75 Blood velocity (μm/s) Chick embryo - 3 days 200 Preliminary data stopped heart 150 IR Control IR Time (seconds)

76 Cell EZ water has negative charge

77 protein

78 with EZ no EZ

79

80 food light absorbed by water

81 Light matters Water matters

82 Water: raw material for building EZ water Green juicing: plant-cell water contains EZ Turmeric, coconut water, etc.: build EZ Sunshine: light builds EZ Sauna: infrared light builds EZ Grounding: negative charge builds EZ
