Well, he won’t be phoning home anytime, say astronomers comparing the mininfrared brightness from 93 unusually bright local galaxies. A study of the galaxies’ emissions at radio wavelengths finds that superadvanced alien civilizations probably don’t exist in our cosmic neighborhood.Siberian cave was home to generations of mysterious ancient humans 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 Zimbabwe Sign up for our daily newsletter Get more great content like this delivered right to you! Country New state-of-the-art DNA analysis on molars reveals that Denisovans not only occupied Denisova Cave in Siberia, Russia, but that they occupied the site over more than 100,000 years with multiple visits, at least 65,000 years apart. The findings also show that the Denisovans weren’t the only ones that took a pit stop at the cave; Neandertals and modern humans checked in as well over the years.Coffee disrupts the body’s internal clockYou may want to think twice about ordering a double red-eye grande latte to help boost your evening energy. Little was known about how caffeine affects the circadian clock, but researchers have discovered that drinking the equivalent of a double espresso 3 hours before bedtime sets your circadian clock back by an average of 40 minutes. The best time for an evening double red-eye is after a long flight west.   A better way to burn calories on your bikeSlow and steady wins the race. This statement seems to hold true based on researchers’ recent discovery of a new equation to describe cycling performance. Ten cyclists’ performances were analyzed based on oxygen uptake but included resistive force with the pedaling rate. So, if you feel more winded on the exercise spinning bike wheeling your legs uncontrollably with no resistance than you do when you turn that resistance knob up and pedal slowly, this new equation helps us understand.Blueprint in hand, NIH embarks on study of a million peopleHoping to avoid the potholes that recently wrecked a similarly ambitious study of children, a panel of human geneticists, medical researchers, and other experts today proposed a blueprint for the National Institutes of Health’s plan to recruit 1 million Americans for a long-term study of genes and health. The study, which hopes to recruit its first volunteers next year and could last a decade or longer, may become the largest national study of this kind in the world.Unless nations act, air pollution deaths will double by 2050, study concludesThe annual death toll from outdoor air pollution could double to 6.6 million globally by 2050 without new antipollution measures, a new study suggests. But policymakers seeking to reduce the death toll will need to clamp down on a wide array of potentially hard-to-control pollution sources—including household furnaces and agricultural activities—that are expected to play a growing role, researchers report.center_img Click to view the privacy policy.
