Most were discovered by accident or are merely synthetic versions of blues already found in nature. In 2009, a chemist stumbled on the first new inorganic blue pigment in 200 years. Today, other researchers are continuing that quest by methodically using physics, chemistry, and genetics to create new blues to dazzle us with.Imported wolves settle in as Lake Superior island teems with mooseThirteen new radio-collared wolves are now scouting Isle Royale in Michigan and feasting on moose, whose numbers this winter reached 2060—the second highest estimate since ecologists began to study predators and prey on the island in 1958. The new wolves, imported to help restore the U.S. national park from overbrowsing by moose, are largely avoiding the territory of the remaining two wolves of the original Isle Royale population. Twenty female moose are also sporting radio collars, allowing biologists to watch both wolf and moose movements online.This shrimplike creature makes aluminum armor to survive the deep sea’s crushing pressureAmphipods—small, shrimplike crustaceans in most aquatic ecosystems—start to fall apart once they hit depths of 4500 meters. There, a combination of crushing pressures, low temperature, and higher acidity causes the calcium carbonate in their exoskeletons to dissolve, making them vulnerable to pressure and predators. Now, scientists have discovered how one species, Hirondellea gigas, can survive in the deepest part of the ocean: with aluminum suits of armor.Neanderthals may have trapped golden eagles 130,000 years agoThe golden eagle has been hunted and revered by human cultures for thousands of years. Yet this may not have been a uniquely human devotion—Neanderthals, too, may have targeted these impressive birds of prey some 130,000 years ago, according to new research. What’s more, modern humans may have learned their eagle-catching techniques from their hominin cousins. Sign up for our daily newsletter Get more great content like this delivered right to you! Country Researchers may have an antidote for the deadliest jellyfish sting on EarthThe sting of a box jellyfish can kill a person in minutes. Scientists have long sought to figure out the secret of its fast-acting venom, which also causes agony, inflammation, and heart attacks. A new study may have the answer—and a potential antidote.Meet the blue crew, scientists trying to give food, flowers, and more a color rarely found in nature Country * Afghanistan Aland Islands Albania Algeria Andorra Angola Anguilla Antarctica Antigua and Barbuda Argentina Armenia Aruba Australia Austria Azerbaijan Bahamas Bahrain Bangladesh Barbados Belarus Belgium Belize Benin Bermuda Bhutan Bolivia, Plurinational State of Bonaire, Sint Eustatius and Saba Bosnia and Herzegovina Botswana Bouvet Island Brazil British Indian Ocean Territory Brunei Darussalam Bulgaria Burkina Faso Burundi Cambodia Cameroon Canada Cape Verde Cayman Islands Central African Republic Chad Chile China Christmas Island Cocos (Keeling) Islands Colombia Comoros Congo Congo, the Democratic Republic of the Cook Islands Costa Rica Cote d’Ivoire Croatia Cuba Curaçao Cyprus Czech Republic Denmark Djibouti Dominica Dominican Republic Ecuador Egypt El Salvador Equatorial Guinea Eritrea Estonia Ethiopia Falkland Islands (Malvinas) Faroe Islands Fiji Finland France French Guiana French Polynesia French Southern Territories Gabon Gambia Georgia Germany Ghana Gibraltar Greece Greenland Grenada Guadeloupe Guatemala Guernsey Guinea Guinea-Bissau Guyana Haiti Heard Island and McDonald Islands Holy See (Vatican City State) Honduras Hungary Iceland India Indonesia Iran, Islamic Republic of Iraq Ireland Isle of Man Israel Italy Jamaica Japan Jersey Jordan Kazakhstan Kenya Kiribati Korea, Democratic People’s Republic of Korea, Republic of Kuwait Kyrgyzstan Lao People’s Democratic Republic Latvia Lebanon Lesotho Liberia Libyan Arab Jamahiriya Liechtenstein Lithuania Luxembourg Macao Macedonia, the former Yugoslav Republic of Madagascar Malawi Malaysia Maldives Mali Malta Martinique Mauritania Mauritius Mayotte Mexico Moldova, Republic of Monaco Mongolia Montenegro Montserrat Morocco Mozambique Myanmar Namibia Nauru Nepal Netherlands New Caledonia New Zealand Nicaragua Niger Nigeria Niue Norfolk Island Norway Oman Pakistan Palestine Panama Papua New Guinea Paraguay Peru Philippines Pitcairn Poland Portugal Qatar Reunion Romania Russian Federation Rwanda Saint Barthélemy Saint Helena, Ascension and Tristan da Cunha Saint Kitts and Nevis Saint Lucia Saint Martin (French part) Saint Pierre and Miquelon Saint Vincent and the Grenadines Samoa San Marino Sao Tome and Principe Saudi Arabia Senegal Serbia Seychelles Sierra Leone Singapore Sint Maarten (Dutch part) Slovakia Slovenia Solomon Islands Somalia South Africa South Georgia and the South Sandwich Islands South Sudan Spain Sri Lanka Sudan Suriname Svalbard and Jan Mayen Swaziland Sweden Switzerland Syrian Arab Republic Taiwan Tajikistan Tanzania, United Republic of Thailand Timor-Leste Togo Tokelau Tonga Trinidad and Tobago Tunisia Turkey Turkmenistan Turks and Caicos Islands Tuvalu Uganda Ukraine United Arab Emirates United Kingdom United States Uruguay Uzbekistan Vanuatu Venezuela, Bolivarian Republic of Vietnam Virgin Islands, British Wallis and Futuna Western Sahara Yemen Zambia Zimbabwelast_img
