Often described

as

'smile

a

carcumzenithal

arc

occurs when

the

sun

shines

at a

right

angle

through

high clouds

(approximately

6100

7600 metres

high) made

of

ice crystals

about

the

size

of

salt

grains,

which refract

the light into

a brilliant

spectrum

of

colour.

The

arc

is

only

visible when

the sky is

free

of

low-level

clouds

and

when

the

sun

sits

less

than about 33

degrees above

ln 1609,

Galileo Galilei

made

an

improved telescope.

Unfortunately,

the

final

image

through Galileo's

telescope

was upside-down.

Modern

telescopes

for

use

on

Earth

have

a different

lens

system

so

that the

final

image

is the

right way

up.

A similar

system is used

for

binoculars.

However,

using

this

lens

system

blurs

the

image very slightly.

Astronomers

looking

Many

metals can be beaten

into

shape.

We say

they are

malleable.

Gold

is

the

most

malleable

metal as

it

can be

beaten

into very thin

gold

leaf.

Gold

is also the

most ductile

metal, as

it

can

pulled

very

fine wire

without

breaking.

Gold

was

once

used

to make

coins,

but

its

main use

today

is

in

jewellery.

Since

gold

is so

prized,

it is called

a

precious

metal. Silver

is another beautiful

precious

metal

that

has been

used

for

jewellery

since

ancient

times.

However,

its main

use

today

is

Children's

that

is

present

at

The

most common

types of children's

hernias

are

umbilical

and indirect inguinal.

Umbilical hernias

may heal without

surgery,

but

indirect inguinal

hernias

probably

will not. Both

umbilical

and

inguinal

hernias

will

Avian

close contact

with sick birds

surfaces.

As

there

is no confirmed

Influenza

viruses,

however, mutate

Scientists

public

experts

fear that

an

avian

flu

strain

might

strike

a

person

who is already

infected

with

a

human

variant

of influenza.

The

two

variants

could

swap, or combine,

their

viral components in the infected

person

before

spreading

to other

people.

This combination

of virus

components

could

even

take

place

in

a susceptible

mammal.

The

result

could

be

a novel

ear has

dog.

Re-attachment

vital to

re-attach

the ear using microsurgical

It takes

an

ordinary

sponge to

take on

a slimy

biofilm.

US

researchers

have

found one

up

to the challenge.

Biofilms

so

when they

discovered

a sponge

in an

otherwise

lifeless section

of ocean,

they

were

amazed.

They noticed

the sponge

growing

unaffected

in a bed

of dead

coral that

was completely

biofouled.

This

led

them to believe

that

the

sponge

produced

compounds

to

fight

off

biofouling,

biofilms

and

bacterial

infections.

When analyzing

the sponge

in the

lab,

the

The

increased

exposure

to

air

increases

the

amount

of

oxygen

available

for

combustion.

For

example,

people

often

use

small

twigs

and

pieces

of

wood

called

kindling

to

start

a

campfire. Kindling

has

a large

amount

of

surface

area

compared

to

its

volume

which

means

that

kindling

heats

and

ignites

more

easily

than

thicker

pieces

of

wood.

Once

ignited,

kindling

Amphibians

tend

to

have

smaller

ranges

and

less

tolerant

of environment

change

than

birds

and

mammals,

making

them

more

vulnerable

to

habitat

loss

and

over-hunting.

Yet

neither

factor

is

responsible

for

their

drastic

population

decline.

Scientists

blame

these

enigmatic

declines

on

the

fungal

disease

chytridiomycosis,

yet

the

fungus

was

present

well

over

a

decade

before

the

sudden

declines

began.

Scientists

suspect

that

environmental

stresses

are

making

amphibians

more

susceptible

to the

fungus.

but

until

today

it

has not

been

used officially

as

anti-cancer

as one

of the

components

of traditional herb for
